Learning from zero trust security case studies is the way to go if you want to implement this kind of security within your company. Let us see some samples below.
Zero Trust Security Case Studies
NSA
One of the case studies in using zero trust security is the National Security Agency (NSA). The NSA is the provider of signals intelligence for the United States and is one of the biggest intelligence organizations in the world. It has to deal with large amounts of data every hour which is why it has to implement a zero trust security policy.
The NSA has several servers, each with high-security levels. The servers are connected by a WAN (Wide Area Network) and are responsible for serving different parts of the world.
The zero trust security case studies of the NSA include:
- It does not trust its internal network as it could be infiltrated by an outsider. It relies on its network, but only for necessary internal purposes.
- Then, it trusts all connections coming from the outside world since they cannot be controlled by anyone else but itself.
- Moreover, it uses a mix of IPS (intrusion prevention system) and IDS (intrusion detection system) to secure its network and server. A firewall is also used to filter all connections coming from outside.
- Finally, its servers are not connected so if one is attacked or corrupted, it will not affect others.’
This kind of security was implemented to prevent a possible breach in any part of the network. This could lead to huge amounts of data being stolen or destroyed by hackers.
Another company that uses zero trust security is Google, a multinational company that provides services. Such as search engines, cloud computing, software development tools, online advertising technologies, and much more.
Google relies on cloud computing as it allows them to connect their different servers regardless of location. And still gives them control over their data once it reaches their servers based on location. So, this means that if a hacker attempts to breach the server, they will not be able to reach data from different locations.
Further, Google also uses a zero trust security tool that monitors all devices coming from outside to the internal network. This is done by scanning the device and checking for the software installed on it to prevent any malicious software from entering the network.
Also, it uses a WAF (web application firewalls) which is responsible for securing its servers. It also uses a proxy server. This is used to filter connections coming in and out of Google’s network. It also implements encryption on all data that passes through its servers as well as double-encryption on all data stored on its servers.
Then, it identifies users based on their principles and assigns them a group that suits their access level.
Zero Trust Security: Conclusion
So, if your company is considering implementing a zero trust security policy, you should consider these case studies. They will help you in implementing the right policy and will also prevent your company from a possible breach.
