Zero Trust Security for Dummies PDF
To begin, let us define what zero trust security is. It refers to a security architecture where every device on the network is treated as untrusted. Except for a defined list of approved devices, which are called Trusted Computing Base (TCB).
Then, the aim is to eliminate any single point of failure and provide strong security for the resources that reside within the organization. It uses a ‘deny all’ approach by default. And it provides access only when it is necessary.
Imagine a bank that has no security guards or cameras outside its main doors. In a Zero Trust Security scenario, this will not be possible because there will always be some level of risk. The same is true in the digital world.
Moreover, it eliminates the walls provided by firewalls and switches and protects the endpoint itself. This is by using micro-segmentation technology. It also uses a single sign-on (SSO) system that does not require users to keep entering their credentials every time they access a resource. Thus, this reduces the overall cost of operation significantly.
Additionally, it is not a replacement for the existing security measures but works alongside them and supplements them. It operates at the application layer of the OSI model, too. Thus, it is a good fit for cloud computing.
Furthermore, it is also designed in such a way that even if there are multiple failures, it will still be able to recover and continue working.
Implementing Zero Trust Security
There are various benefits of this security architecture as well. For example, it helps in faster detection in case of an attack. However, to implement this in your organization, you need to make any changes. This includes replacing all existing security controls with new ones. And ensuring that all the existing resources are made available through this new infrastructure.
Also, if you have a large organization, then implementing this across all your endpoints will be a huge task. Thus, most organizations prefer to start with a pilot project and implement it in parts.
Also, the standard practice is to hire skilled professionals for this task. However, if you have some experience in this field already, you can handle it yourself as well.
Aside from that, you can also start with a small project first. For example, you can restrict a sensitive server to only a few users. Then, slowly, increase the number of users who are allowed to access it. This will help you understand how the system works and what its limitations are.
Moreover, the biggest benefit of this system is that it reduces the overall cost while providing security to the endpoints. It is also beneficial in case of emergencies as it allows faster recovery.
