Zero trust definition in Cybersecurity

Zero Trust is a way of keeping computer systems safe that doesn't automatically trust anyone or anything, both inside and outside of a company's network. Instead, it checks everything trying to connect to the system before letting it in. This helps keep the bad guys out and the important information safe.

Here's how Zero Trust works?

  • Never trust, always verify: Don't just trust anyone. Make sure who or what is trying to connect is really supposed to be there, every single time.
  • Least privilege access: Only give people or systems the bare minimum they need to do their job. If they don't need access to something, they shouldn't have it.
  • Microsegmentation: Break up the network into smaller, separate parts so if one part gets attacked, the others are still safe.
  • Multi-factor authentication (MFA): Use more than one way to check if someone is who they say they are, like a password plus a code sent to their phone.

Zero Trust helps make sure that the only people and systems that can get into the network are the ones that are supposed to be there, making everything a lot more secure.
