1
So if you have a cybersecurity interview tomorrow or
2
if you've been studying cybersecurity for a while and you want to see what interview questions we ask entry -level candidates,
3
then this video will have everything that you need.
4
I'm going to share with you 25 entry -level cybersecurity interview questions and answers from real cybersecurity professionals.
5
In each question, you will get the correct answer and the incorrect answer.
6
This way, you learn what to do and what not to do in an interview.
7
Now the video is divided into five sections.
8
Each section will contain five interview questions focusing on one cyber security specialization.
9
Now I didn't prepare all those questions.
10
I've prepared five questions with the focus on GRC.
11
I've reached out to four cyber security professionals each with expertise in different domains.
12
So for general entry -level cyber security questions,
13
my friend Sandra have prepared five questions and for questions focused on security operation center or SOC analyst skills my friend
14
Josh who is a highly experienced cyber security professional especially
15
when it comes to detecting and responding to cyber attacks have prepared five questions
16
and for network security I reached out to Royden who is a network security engineer
17
and he prepared five entry -level questions focused on network security
18
and finally for cloud security my friend William prepared really interesting cloud security focused questions.
19
Now after each section I will also be sharing with you five common interview mistakes
20
that I see entry -level candidates make all the time.
21
Now I've been a hiring manager for a long time
22
and trust me when I tell you this I see the same mistakes over and over.
23
So please make sure you don't skip watch the video until the end because it's packed with important information.
24
Starting with part one general cyber security questions.
25
Starting with question one, how do you stay current with cybersecurity threats and cybersecurity news?
26
And the wrong answer is?
27
Yeah, so I just scroll through Twitter and see what people are talking about.
28
If something big happens, I usually find out since someone will eventually tell me about it.
29
The correct answer would be?
30
So I subscribe to threat intelligence feeds like CISA and Krebs on Security.
31
I also actively follow CVE announcements and participate in cybersecurity communities like the Reddit NetSec and OWASP.
32
And I also run my own home lab environments to test emerging threats
33
so I can understand them hands -on and get some hands -on experience as well.
34
Question number two, explain the difference between a vulnerability, a threat, and risk.
35
And the wrong answer is?
36
I mean, they're all basically the same thing.
37
And the correct answer is?
38
So a vulnerability is a weakness in a system.
39
A threat is something that can exploit that vulnerability.
40
And the risk is the potential impact if that threat was successful.
41
For example, if an unpatched server is a vulnerability, ransomware is the threat, and the risk is data loss and downtime.
42
Question 3 is a practical question, so walk me through the steps that you will take to investigate a phishing incident.
43
And the wrong answer is?
44
I'd probably just tell the user to delete the email and move on.
45
It happens every day, so I can't respond to every single user that gets a phishing email.
46
And the correct answer is?
47
Okay, so first I'd isolate the affected user and then collect the email headers and content, and then I'd check the sender domain,
48
any links, any attachments that are in the email, using sandboxing tools.
49
If there is a compromise suspected, then I'll also review login activity for suspicious access, reset credentials, and also scan for persistence.
50
And then finally, I'd have to document all this into an incident
51
and deploy awareness messaging to prevent any reoccurrence for other future users that might be getting the same email.
52
Question number four is what would you do if you detect an alert at 2 a .m.?
53
And the wrong answer is...
54
I usually wait until morning unless it looks serious.
55
I mean, someone more senior on the team will eventually answer the alert before I ever do.
56
And the correct answer is...
57
Yeah, so this will depend on the severity classification.
58
So for critical alerts tied to high -risk assets, typically for these, I'll immediately investigate using any logs or SIM queries.
59
And if confirmed, then I'll follow the escalation runbook and notify the on -call team
60
and then for lower priority alerts i'll usually log them
61
and batch them for review during scheduled response hours question number five is tell me about a time
62
when you had to explain something technical to a non -technical stakeholder
63
and the wrong answer is uh i just told them they wouldn't understand
64
so i didn't even bother to explain and just handled it myself
65
and the correct answer is
66
so in a previous role a manager was frustrated about multi -factor authentication delays and instead of going deep into authentication protocols,
67
I basically explained to them that MFA acts like a second lock on their door.
68
It adds a few seconds but prevents any costly break -ins.
69
Then they immediately understood the trade -off and supported enforcing MFA org -wide.
70
So those are really common questions that we ask sometimes to just get to know the candidates,
71
how they talk, how they think and obviously Sandra was joking with some of those incorrect answers.
72
Now the first mistake that candidates make all the time
73
that I don't want you to make
74
which is really don't go to the interview unprepared and by preparation I mean know yourself stuff.
75
For example, the question about the difference between a vulnerability and a threat and a risk.
76
Really, really basic stuff.
77
And you'd be surprised how many candidates get that wrong.
78
Now as an entry level candidate, I always recommend that you do something like the Google Cyber Security set.
79
Why?
80
Because it actually covers all of these beginner concepts in an easy to understand manner.
81
They go into detail into these definitions, but they also teach you things like operating systems and networking, which are really common interview questions as well.
82
You can't bluff your way into the interview because we will quickly know whether you know your stuff or not.
83
And as an entry -level candidate, the Google Cybersecurity Cert actually gives you 30 % discount to get the CompTIA Security Plus,
84
which is a good combination that covers a lot of the concepts that we ask about in interviews.
85
I'll leave a link to all the resources in the description box below, so keep an eye out for any discounts or any offers.
86
Now part two of this video, we're gonna cover questions focused on Security Operations Center and the defensive side of cybersecurity.
87
However, remember, these are not advanced questions.
88
These are entry -level questions.
89
And for that, my friend
90
Josh has prepared the questions and answers.
91
Question number one, what are the key differences between patch management and vulnerability management?
92
And how do they work together in a cybersecurity program?
93
And the wrong answer is?
94
Yeah, so the key differences between patch management and vulnerability management, patch management just means applying the patches on the different computers,
95
where vulnerability management means remediating the vulnerabilities
96
and these things come together to make the environment more secure
97
and the correct answer is yeah so the key differences between vulnerability management
98
and patch management so patches are pretty much always counted as vulnerabilities it's
99
when an update or something comes out for an os
100
or a platform you apply a patch to it to kind of like fix the hole
101
or remediate whatever happened where vulnerabilities are not always patches vulnerabilities can be misconfigurations in an operating system, an open port on a firewall,
102
some out -of -date software.
103
It can be many different things.
104
So patches are like a subset of vulnerabilities and patch management
105
and vulnerability management come together to help reduce the overall risk of the organization
106
and keep it low through like an iterative patch management and vulnerability management life cycle.
107
Question number two, walk me through how you would detect and monitor cyber threats in a security
108
Operations Center, what tools and frameworks would you use?
109
And the incorrect answer is?
110
Yeah, so to monitor and detect potential threats in a SOC, we would use our SIM, we'd configure alert rules in there,
111
and then when an alert got triggered, we would just respond to it.
112
And then as far as frameworks go, we would probably just stick to NIST.
113
And the correct and better answer is?
114
Yeah, so how I would monitor, detect, and respond to potential threats in the Security Operations Center, as well as what frameworks I might utilize.
115
So in my personal environment, I use an EDR platform as well as a SIM, EDR being Endpoint Detection Response, and then SIM being
116
Security Information and Event Management System.
117
So basically the EDR platform, we use Microsoft Defender for Endpoints,
118
and we will install an agent on all the end user devices as well as the servers.
119
And these will collect logs and will send them to a centralized repository, which will be forwarded to the SIM and then both the EDR platform
120
and the sim has the ability to look at the logs like at a holistic level
121
and correlate events that are happening and
122
if something anomalous comes up we have the ability to spin up an alert
123
and the alert can be created like either in the EDR platform
124
or the sim we typically will use the sim as a more centralized area for incident management
125
and as far as working incidents we'll stick to NIST 861 the incident response the computer incident response lifecycle.
126
Pretty much all security incidents can be handled with this.
127
It basically goes like detection and then the analysis of the incident to make sure it's like a true positive.
128
And then you move on to like the containment
129
and eradication of it and then the recovery phase
130
and then a postmortem to see like what you can fix and make it better in the future.
131
Question number three, tell me about the time
132
when you had to respond to a cybersecurity incident and what was the outcome of that?
133
And the wrong answer is?
134
Yeah, so responding to an incident.
135
One time at work, one of our virtual machines was exposed to the internet
136
and some hackers brute forced it and got logged into it
137
and ended up spreading crypto miner like ransomware all throughout the network.
138
We ended up getting a warning from Microsoft saying that there was Moses traffic coming from our organization.
139
In the end, I think we had to just delete a bunch of virtual machines
140
and then write a letter back to Microsoft.
141
And the correct answer would be?
142
Yeah, so a time when I had to respond to a cybersecurity incident.
143
So one time in our Azure subscription, one of the main network security groups, it's kind of like a firewall, had a misconfiguration in it.
144
And it was allowing all kinds of traffic inbound and outbound.
145
It was like a total, total mistake.
146
But eventually, of course, a lot of the virtual machines in our subscription were discovered on the public Internet.
147
And this happened really fast.
148
Like a brute force attack happened somebody got logged into one of the virtual machines
149
and then they spread laterally throughout the network and they installed crypto miners on probably like
150
it was like five virtual machines
151
and after this very quickly those five virtual machines would launch attacks outbound to the network
152
and they were attacking all sorts of different organizations
153
and microsoft actually noticed this because the organizations reported it and they sent a warning
154
to my personal email saying that we need to stop that
155
or the sub the whole subscription is going to be brought down, which had over like about 350 virtual machines inside of it,
156
as well as like almost a thousand users.
157
So very quickly, the task at hand was to immediately quarantine everything
158
and stop the inbound and outbound traffic as soon as possible.
159
So this basically involved me making an inbound firewall rule on
160
the network security group to prevent almost all traffic inbound
161
and then the outbound traffic was heavily heavily limited to tcp port 443
162
and then a couple other ports that were required
163
and then after this initial quarantine um
164
i led an investigation to figure out like where the actual
165
like uh compromise happened like the port of entry how far everything spread
166
and then what actually ended up getting affected
167
and then after everything was identified the machines were not really critical to what we were doing they're not business critical.
168
So we could easily like immediately shut them down and just wipe the virtual machines.
169
And then after everything was wiped, the firewall rules were verified that the inbound and outbound traffic was as it was supposed to be.
170
And then Microsoft was alerted of our remediation efforts and then operations returned to normal.
171
Question number four, how would you prioritize and communicate security risks to non -technical stakeholders?
172
And the wrong answer is?
173
Yeah.
174
So to prioritize and communicate security risks to a non -technical audience, we just do our best to use words that they're more likely to understand,
175
like less technical jargon.
176
We try to dumb it down as much as possible with the hopes that they understand.
177
And the correct answer is?
178
So to prioritize and communicate security risks to non -technical stakeholders and leadership, basically it just comes down to speaking their language.
179
And in order to do that, you have to understand what those particular groups of people care about.
180
So generally speaking for non -technical people,
181
you just want to relate what you're saying to some kind of easy to understand real life scenario the best
182
you can and then in terms of elite leadership
183
and then in terms of leadership
184
and especially senior leadership you want to quantify everything you're saying like put a dollar amount
185
or some kind of number on it
186
so they can understand they have to understand things at a really high level
187
and you can't be talking about like binaries like like really specific vulnerabilities
188
and stuff like that you have to like equate it to like the big picture
189
and put a number on it and then how it will affect the business from like a quantitative or a numbers standpoint.
190
Question number five, how do you see AI used to enhance cybersecurity defenses
191
and what potential risks would it introduce to the environment?
192
And the wrong answer is?
193
Yeah, so how I see AI being used to enhance cyber defense and the associated risks,
194
there's definitely going to be a lot of companies coming out with solutions
195
that use AI and machine learning to quickly find anomalies and raise alerts faster than a human analyst would.
196
And as far as risks go, I think a lot of jobs are at risk of being taken over by AI and machine learning,
197
especially in cybersecurity.
198
I've been seeing a lot on Reddit about this lately.
199
And the correct answer is?
200
Yeah, so how I see AI enhancing cyber defenses?
201
I'm actually experimenting with this quite a bit.
202
I created a cybersecurity AI agent that uses ChatGPT's API endpoint
203
that will do a threat hunt against really large log sets
204
and try to correlate the data and see if anything anomalous or malicious comes out in the logs.
205
And I've come to find that it can analyze the logs
206
and create a threat report like 200 to 300 times faster than a human can do it, depending on the model that you use.
207
And it just works really, really well.
208
So there's a lot of applications for LLMs.
209
And as far as generative AI goes, there's a lot of applications for this as well.
210
But one of the ones that really stands out to me is being able to do really customized phishing campaigns.
211
You can prompt the AI to have it do certain scenarios
212
or certain levels of difficulty with different typos
213
or try to make it really, really hard
214
and we'll craft like a phishing campaign email
215
and you can use those to like test your users and then test your security awareness training and security posture.
216
But as far as risks go, there's a lot of risks as well.
217
Like some of them, when it comes to my, the agentic AI that I built for threat hunting,
218
like some of the risks around that are you have to provide guardrails for it
219
because if you just let the agent do whatever, it might end up spending too much money
220
if it uses the wrong model or
221
if it analyzes like.. really huge data set
222
that doesn't need to be analyzed um you could have excessive spend some other risks are depending
223
if you're like in -housing the model like
224
if you're using like i forget what it's called
225
but like open ai for azure for example where you can
226
in -house the model versus using open ai's like their model
227
like you don't want to be sending user data to
228
that public endpoint model because you don't you don't know what they're doing with it right
229
so you need to be considerate of that, like where you're sending the data, right?
230
And you need to be considerate of what kind of data that you're sending to the model.
231
Or if you're like training the model,
232
you don't really want to send PII to it or like some other data that could get you in trouble.
233
There's just a lot to worry about in terms of like data privacy and guardrails.
234
But yeah, that's been my experience with it.
235
So I think people are going to use generative AI specifically and large language models a lot for analysis in the future.
236
So I really like the way that
237
Josh has framed his answers, both the incorrect and the correct.
238
And if you noticed, a lot of the incorrect answers were actually correct.
239
However, the good answer was a lot better because in many instances, it actually had a lot of details.
240
And those details show that you have done the work.
241
Which brings me to the second big mistakes that people make in cybersecurity interviews,
242
which is just learning theory if someone have just learned theory through multiple choice based certifications and questions and answers, usually they answer the way that
243
Josh answered the wrong way, which is they have surface level answers and they probably have memorized them however, if you notice the way
244
Josh answered in a good way, he gave you a lot more details so when he talked about a cyber security incident he investigated,
245
he showed you a real example where he followed methodology
246
he was able to tell you precisely what framework he used and what he used it for.
247
This is not something that you can memorize.
248
This is something that you have to do it practically.
249
And the way to do that is by doing practical hands -on training that I talk about in my videos.
250
You cannot theorize your way into a cyber security job.
251
It's really easy for me
252
or any hiring manager to quickly find out whether you've done the work practically or you've just memorized stuff.
253
Now if you haven't worked in a security operation center and you don't have an example of an incident,
254
you can share an example of an incident that you've done in a practical hands -on lab using platforms that I recommend.
255
I covered all of this practical hands -on training in this video.
256
Please check it out and make sure you do everything in the video
257
if you want to have the confidence to pass cybersecurity interviews.
258
Now in part 3 of the video, I will share with you 5 cybersecurity GRC questions that we ask for entry -level candidates.
259
However, please note that these questions we also ask for general cybersecurity jobs.
260
So even if the job is not GRC, those are basic foundational knowledge that everyone in cybersecurity should know the answer to.
261
Let's unpack it in part 3 of this video, GRC.
262
Question 1.
263
What's the purpose of a risk register?
264
And the wrong way to answer this is to say something like,
265
the risk register is just a list of problems that we identified and we only updated when there is a cyber attack.
266
So it has a list of things like phishing attacks and compromised user accounts.
267
Now the correct way to answer this is to say the risk register is a document used to track risks,
268
their likelihood, their impact, their assigned owners, and any mitigation strategies or compensating controls.
269
It helps organizations manage risks.
270
It also gives visibility to senior stakeholders of all the risks that their systems or organization is exposed to,
271
and it helps ensure that risks are managed in line with the risk appetite of the organization.
272
Question number two, what's the difference between a policy and a procedure?
273
The incorrect answer is to say that a policy and a procedure are exactly the same thing.
274
It's just a way to tell people to do something.
275
For example, a policy or a procedure just tells you that the password should be 16 characters long.
276
Now, the correct answer is the policy sets a high level rule or expectation,
277
whereas the procedure tells you exactly how to implement that rule or that expectation.
278
For example, the policy will tell you that you need to have your data protected by certain encryption standards.
279
The procedure, however should tell you exactly how to encrypt the data
280
and what steps you need to take to protect that data.
281
The procedure will also have details about access levels and who can access what and the steps to implement that.
282
Question number three.
283
Why is compliance important in cyber security?
284
The incorrect answer is to say something like compliance is just paperwork
285
and tick the box exercise that we need to do because of auditors.
286
It doesn't actually provide any real security to the organization.
287
The correct answer is to say that compliance is something necessary for organizations to meet their contractual obligation,
288
their legal obligation, and their regulatory obligations.
289
It's an essential requirement for the organization to exist and do business.
290
Additionally, it provides a level of trust for their customers.
291
For example, providing an evidence that the application that you sell to customers is ISO 27001 certified.
292
will provide a level of assurance to the customers that your organization takes information security seriously.
293
Question number four is what is asset management and why is it important for organizations?
294
The incorrect answer would be to say
295
that asset management is simply having a list of all the serial numbers of all the tools
296
and devices that the organization have without really explaining why.
297
The correct answer would be to say that asset management is the process
298
that the organization should establish to identify and classify all of their assets.
299
Those assets could be information assets, they could be applications, they could be software, could be hardware, or they could be intellectual property,
300
or even key personnel with certain expertise.
301
Those assets should be classified as per criticality and sensitivity and the importance to the organization, and there should be an established process to identify
302
and regularly update an information asset register where we track all the assets based on their criticality and sensitivity.
303
We also need to use the asset register.
304
The asset register is also important for the organization to prioritize protecting certain assets.
305
For example, an application holding extremely sensitive data should be a priority for the organization to invest in protecting that application.
306
Whereas another application that doesn't hold sensitive data, the organization can afford not to put expensive security controls to protect that application.
307
Question number five, what's the difference between inherent risk and residual risk?
308
The incorrect answer would be to say
309
that the residual risk is the risk that's left after we implement something and we don't care about it,
310
while the inherent risk is something we cannot protect.
311
Now the correct answer would be the inherent risk is the risk that we have before we implement a control.
312
For example, if we have an application exposed to the internet,
313
well the inherent risk is that it will most definitely be attacked by bots and hackers and random attacks.
314
That's the inherent risk.
315
Now when we apply a control such as a web application firewall, we reduce that risk.
316
However, the risk is not going to be zero.
317
So there will be residual risk.
318
There will be other risk.
319
For example, we still need to manage user access to that application.
320
So that's another risk.
321
And therefore, we need to apply further controls.
322
And in the real world, no matter how many controls we apply, we will always have a level of residual risk.
323
We just need to determine what residual risk the organization is happy to accept in line with their risk appetite
324
now those grc questions believe it or not are actually entry -level
325
and we ask them to candidates even for jobs like sock analysts sometimes
326
or even cloud security professional
327
and the reason is as a cyber security professional you're expected to know what risks mean
328
and how to handle it especially
329
if the job is more of a generalist where you're expected to do more than one thing
330
this is really common for small to medium -sized organizations where
331
they can't afford to have someone who's dedicated to doing just one thing now the biggest mistake
332
that i see candidates make when it comes to entry -level interviews is
333
that they are hyper focused on one specialization for example i'll look at their resume
334
and all they've done is penetration testing or all they've done is incident response
335
or detection engineering this is all well
336
and fine however as i said a lot of jobs are looking for someone who's a generalist
337
so they have knowledge in more than one area
338
and therefore i highly encourage you to diversify your skills and add at least GRC and cloud security to your knowledge.
339
Now for GRC we cover all of this in detail in GRC Mastery
340
so go to grcmastery .com have a look at it.
341
It's fully practical fully hands -on with practical use cases using real companies reports.
342
So please check it out to give yourself a better chance at passing cyber security interviews.
343
Now part four of this video is focused on network security questions and again those are entry -level cyber security questions.
344
The questions are prepared by my friend Roy
345
and I'll put a link to his YouTube channel in the description box of this video
346
so please make sure to check it out and let's see the questions.
347
So question number one, what is the difference between a firewall and an IPS slash IDS?
348
So the incorrect answer is they're basically both the same thing
349
and they block hackers from entering your network and in theory you just need one of them to do the job.
350
The correct answer is A firewall filters traffic based on security rules, allowing or blocking traffic, and usually sits at the network perimeter.
351
An intrusion detection system usually is used to detect network threats and attacks and alerts the administrator,
352
whereas an IPS can block these attacks in real time.
353
For a layered defense approach, all three of them are highly recommended.
354
But in today's time, firewalls come with an IDS and IPS built in, and therefore they are called as next generation firewalls.
355
So question number two, what is the difference between symmetric and asymmetric encryption?
356
The incorrect answer is symmetric encryption is older and slower, whereas asymmetric encryption is the one that everyone uses today.
357
Symmetric encryption uses just one key, whereas asymmetric encryption uses two keys.
358
The correct answer is that symmetric encryption is the one that uses one key and is generally very fast.
359
However, it tends to be a little unsecure when it comes to actually sharing the key.
360
Asymmetric encryption, on the other hand, uses a public and private key pair.
361
The public key is used by the sender when it's encrypting a message,
362
whereas the message is then decrypted on the receiver's end using the private key.
363
SSL TLS uses a good combination of symmetric and asymmetric encryption.
364
All right, question number four.
365
What is a VPN? and why do we need it?
366
So the incorrect answer to this is, a VPN is mainly used to hide your IP so that you can watch Netflix from other countries.
367
Companies generally use VPNs so that users can connect into the office network.
368
The correct answer is that a VPN
369
or a virtual private network creates an encrypted tunnel from the user to the site that it's trying to access.
370
Companies use it because it helps protect data that's going through the tunnel from any eavesdropping or network -based interception attacks.
371
With regards to VPNs, you've got different types of VPNs like side -to -side VPNs, SSL VPNs, remote access VPNs, cloud VPNs, etc. Question number four,
372
what are the common types of network attacks?
373
An incorrect answer to this question is that hackers usually just guess passwords or use viruses.
374
But as long as you've got an antivirus installed, you should be good and you don't need to worry about it.
375
The correct answer for this is going to be network -based attacks are of different types, such as DOS or DDoS,
376
where you've got a lot of packets flooding the network, for example.
377
You've also got man in the middle where communications are intercepted by a hacker.
378
You've also got phishing attacks where hackers try to trick you into revealing your credentials, for example.
379
In order to evade these types of network attacks, you can have a lot of defenses in place such as network segmentation,
380
monitoring, as well as using strong encryption standards.
381
And question number five, how would you secure a company's
382
Wi -Fi network?
383
So the incorrect answer would be that just set a strong password so that nobody can guess it easily.
384
What you can also do is just hide the network SSID so that hackers can't find your wireless network.
385
The correct answer for this would be at start of by first using WPA3 encryption and also disable WPS.
386
I would also change the default credentials on all of the routers.
387
Along with this, I would look to enable
388
Mac filtering as well.
389
What I would then do is segment your network using VLAN segmentation and have them on different firewall zones,
390
one for a guest network and one for the staff or corporate network.
391
And finally, I would then use StackAx or Radius for authenticating users.
392
Now, as you can see, a lot of the answers that
393
Troy provided, the wrong ones weren't really wrong.
394
However, to really stand out, you need to provide a level of detail that show that you have true understanding, which as I said earlier,
395
only comes from practical hands -on learning.
396
Now the fourth big mistake that I see a lot of entry -level candidates make is
397
that they don't do enough research on the job.
398
Now this can get confusing, so let me clarify it for you.
399
For example, let's say you have an interview tomorrow with an insurance company.
400
What I want you to do is just research what the company does and what it's all about.
401
Now some people spend so much time doing this and they start reading financial reports.
402
Please don't do that, it's really not required.
403
It also doesn't really impress anyone.
404
Just know what the company does or I'm really passionate about policies because everyone knows that you're just making stuff up.
405
So you're not fooling anyone.
406
Be honest, be truthful and know your stuff.
407
That's the most important thing.
408
Now, part five is a favorite of mine, which is cloud security.
409
The questions are prepared by my friend William.
410
I'll leave a link to his Instagram account.
411
He posts a lot of good stuff about cloud security.
412
So please pay attention.
413
And remember, those questions are really common.
414
I ask them for most of my entry level cybersecurity interviews, even if the job is not specifically cloud security.
415
Let's go to part five, which is cloud security.
416
Hey nerds, W .J.
417
Pearce here.
418
Really excited to be on this Unix guy video.
419
I want to start with five beginner cloud security interview questions that I think you might be asked in an upcoming interview.
420
So for each one, I'm going to give you what I feel would be a really good and correct answer.
421
And then I'll give you a incorrect and maybe not so full picture answer.
422
So question one, What is Role -Based Access Control or RBAC and how is it implemented in a cloud platform?
423
So role -based access control is a security model effectively where permissions are assigned to roles rather than individual users
424
and users are then assigned to those roles based on their job function.
425
So in a cloud platform like AWS using IAM, RBAC is implemented by creating roles like developer,
426
security, auditor, database admin, and then specific permissions are assigned to those roles.
427
You then assign users or service accounts to those roles.
428
This kind of simplifies the whole permissions management
429
and ensures users only have access to what they need for what they're responsible for.
430
And that's also known as the principle of least privilege, which you've probably heard before.
431
A wrong answer here might be that RBAC means each user has their own custom role with specific permissions tailored to them.
432
And that's wrong because that's sort of the - opposite of what RBAC is.
433
RBAC uses like a shared standardized roles based on job functions, not user customization.
434
So the latter thing that you would be describing there is direct user permission assignment,
435
which is an option, but it doesn't really scale and it's very hard to manage.
436
Moving on to question number two, and I was actually asked this in my first ever cloud security interview.
437
What is the difference between encryption at rest and encryption in transit and of a cloud -based example.
438
So encryption at rest protects data while it's stored on a disk or a database, ensuring that if somebody does gain access to it,
439
you know, the storage or the backup media, they can't read the data without the encryption keys.
440
Now, you might already know that.
441
But encryption in transit, however, protects data while it's moving between two different locations,
442
like from a user's browser to a server or between two different cloud services.
443
And it effectively prevents successful eavesdropping attempts during transmission.
444
Now in the context of the cloud, at rest think about your files stored in AWS S3.
445
In a bucket they're encrypted using AES256 encryption on the disk.
446
And in transit when you upload those files to S3 they travel over HTTPS or TLS, encrypting the data as it moves across the internet.
447
Now a wrong answer here might be that encryption in transit is only needed for public internet connections.
448
Internal cloud traffic doesn't need it.
449
Now that's wrong because even within a cloud environment, traffic between two different services, it really should be encrypted.
450
Attackers who do gain access to your VPC or your network, they can intercept unencrypted traffic and then they could, you know, read it.
451
It's all about minimizing that blast radius
452
if an attacker does get into your network with encrypted internal traffic there's not much they can do.
453
Question three a real fundamental one here what is a security group
454
or a network security group and how does it work in a cloud based environment?
455
So a security group is a virtual firewall effectively that controls inbound
456
and outbound traffic to your cloud resources so like a virtual machine
457
or a container and it works by defining rules that specify
458
which traffic is allowed based on a couple of things protocol port and source and destination IP addresses.
459
Now security groups are stateful, which means if you allow inbound traffic,
460
the return traffic is automatically allowed without needing a separate outbound rule.
461
If you remember one thing from my section of this video, it's the difference between stateful and stateless security groups.
462
So a wrong answer here would be that a security group encrypts traffic that's passing through it.
463
Now I've heard that answer before and it's wrong.
464
Why is it wrong?
465
Well security groups only control whether traffic is allowed or denied.
466
They don't actually encrypt or decrypt or even inspect the contents of the traffic.
467
Question four and a personal favorite of mine really important if you want to be a cloud security engineer.
468
What is infrastructure as code or IEC and what are the security benefits?
469
So infrastructure as code is the practice of managing infrastructure through code rather than manual configuration.
470
Now there's a ton of security benefits that you get from this
471
and some of them might include consistency which is going to help you minimize
472
that human error that you typically get from a manual setup.
473
Next you get version control and that means you can track all your changes and who made them.
474
You get automated security scanning if you configure it mean
475
that you can start detecting those security misconfigurations before deployment and finally you get repeatability,
476
which means all those security controls that you've spent a long time building up, they're applied consistently across all your cloud environments.
477
Now, a wrong answer here would be that IAC is mainly for automation and speed.
478
It doesn't really improve security.
479
Now, that's wrong, and it's wrong because IAC significantly improves security through that consistency and the ability to catch misconfigurations early.
480
Now, manual configurations are super error -pone and really hard to audit.
481
IEC makes security controls repeatable and verifiable.
482
Finally, the last question here and something I consistently talk about, one of the most important questions,
483
what is the purpose of secrets management in a cloud -based environment?
484
Now, a really good answer here I think would be
485
that secrets management is the practice of securely storing and accessing and managing sensitive information.
486
So what do we mean by that?
487
So think about things like password, API keys, database credentials and tokens.
488
The purpose here is to prevent secrets from being hard -coded into application code or configuration files.
489
They provide a place of centralized control and they enable automatic rotation of credentials, which is pretty cool.
490
They ensure secrets are encrypted both at rest and in transit.
491
And long story short, proper secrets management reduces the risk of credential exposure and credential based attacks.
492
Now if you want to set this up you can make use of something like HashiCorp Vault or AWS Secrets Manager.
493
Seriously, if you learn one thing from this video, learn secrets management.
494
And a not so good answer here would be that secrets management is just about encrypting passwords in a database.
495
Now that's not entirely wrong, but it's not the full picture.
496
Secrets management is a much broader topic and it includes things like secure storage, access, control, auditing, logging, automatic rotation,
497
distribution to applications, and lifecycle management.
498
It's not just about encryption, it's the entire process of handling sensitive credentials.
499
That's all for me.

If you're interested in a career in cloud security, drop a comment below
501
because I think it's really cool to see how many people are actually passionate about this field these days.
502
I've been W .J.
503
Pearce.
504
I'm now going to pass it back to Unix guy.
505
Now, as you can see, William has given you so much detail and information that's really important for anyone who wants to work in cybersecurity.
506
Now, the fifth and in my opinion, the biggest mistake that entry -level candidates make in interviews is,
507
believe it or not, coming unprepared especially with knowledge i know i said at the beginning know your stuff
508
but what i see is sometimes candidates only do one certification for example they'll only do comp day security plus
509
and that's it and then they are surprised
510
when we ask them questions about cloud or grc
511
or network security yes the google cyber security certificate is a great start however this is just a starting point
512
if you are a minimalist and you just want to do one
513
or two training courses then you are going to be disappointed.
514
Yes, some people will be able to land the job with just one training course.
515
However, most of us had to do a lot more.
516
Cybersecurity is a new field for you and you need to give yourself a chance to land the job.
517
Therefore, I highly, highly recommend you follow this roadmap
518
because I lay out a progressive step -by -step plan for you to follow
519
that will build your skills and will enable you to pass any cybersecurity interview.
520
Check it out and I'll see you there.
