Shadowing Practice: Zero Trust Explained in 4 mins - Learn English Speaking with Video
Les maken...
1
Zero Trust is a security strategy that says you shouldn't grant implicit trust to a user,
2
device or an application based solely around some property about them, like their network location.
3
Over the next few minutes, I'll explain exactly what we mean by this and how IBM can help.
4
But let's be really clear upfront.
5
Zero Trust isn't something that can simply be delivered by implementing a new piece of technology, nor is it a point product or service that you can just go out and buy.
6
It's a security strategy that has three core principles.
7
But before I come on to those, let me explain why organisations are increasingly moving on from the previous popular model of perimeter security.
8
Firstly, there's this somewhat medieval notion
9
that you have a perimeter to your network where you build the walls as high as possible
10
and try and stop malicious actors at the gates.
11
This no longer works because employees are working from home more than they're working from the office,
12
and because hybrid cloud is now clearly the preeminent platform for enterprise infrastructure.
13
So it's an increasingly complex problem to even define a perimeter.
14
Secondly, the concept of trust is a very human one that we've taught computers to adapt to.
15
For example, if I see Helen every day in the office wearing her employee badge, I trust that she's an employee and is there for the right reasons.
16
In reality, I don't actually know that she wasn't let go last week for misconduct, and is now back in the office trying to steal corporate data.
17
So a computer security model based on a human definition of trust is inherently flawed,
18
particularly in a world where attackers are finding it easier than ever to steal credentials and disguise themselves as trustworthy.
19
Without a zero trust security model, once an attacker is in the corporate network, they can move laterally to new systems with relative ease.
20
This brings me on to the first defining principle of the Zero Trust model: Never trust Always verify.
21
Just because somebody's on your corporate network and is carrying
22
that badge with an employee name on it doesn't mean that they are who they say they are, or that they're necessarily well -intentioned.
23
So this always verified piece refers to the fact that every time something like a user, device or application tries to make a new connection attempt,
24
that attempt should be rigorously authenticated and authorised, and not simply trusted because it's coming from inside the corporate network, for example.
25
Implement least privilege is the second core principle of a zero trust architecture, which says you should only grant users and applications the minimum amount of access
26
that they need to perform their job effectively and no more.
27
Privileged access management is a great way of implementing least privilege for admin users, for example.
28
And then finally, assume breach.
29
This is my favourite of the zero trust principles
30
because it encourages teams to plan for the worst case scenario
31
and build robust and tested incident response plans so that when attacks do occur, the time to respond is rapid and well practised.
32
Not only this, but this principle encourages organisations to shrink the target
33
and the impact zone of an attack through networking principles like micro -segmentation.
34
So how can IBM security help?
35
We recognize that different clients will have different business drivers and priorities for why they want to deploy Zero Trust.
36
So we've created four actionable blueprints depending on where you want to start.
37
They are Reduce the risk of insider threat.
38
Secure the remote workforce.
39
preserve customer privacy, and protect the hybrid cloud.

- Begin op 0,75× snelheid, spreek zin voor zin na en ga terug naar normale snelheid zodra het makkelijk gaat.
- Neem jezelf op en vergelijk met het origineel; let daarbij op woorden als perimeter, attacker, authenticate.
Wat is de Shadowing-techniek?
Shadowing is een wetenschappelijk onderbouwde taalleermethode die oorspronkelijk is ontwikkeld voor professionele tolkentraining en gepopulariseerd door polyglot Dr. Alexander Arguelles. De methode is eenvoudig maar krachtig: je luistert naar native Engelse audio en herhaalt het onmiddellijk hardop — als een schaduw die de spreker volgt met slechts 1–2 seconden vertraging. In tegenstelling tot passief luisteren of grammaticadrills, dwingt shadowing je hersenen en mondspieren om echte spraakpatronen tegelijkertijd te verwerken en te reproduceren. Onderzoek toont aan dat het de uitspraaknauwkeurigheid, intonatie, ritme, verbonden spraak, luisterbegrip en spreekvaardigheid aanzienlijk verbetert — waardoor het een van de meest effectieve methoden is voor IELTS Speaking-voorbereiding en echte Engelse communicatie.
