Zero Trust

What is Zero Trust?

Today’s modern IT environment typically has: remote workers, cloud and mobile devices making the traditional security model of a strong perimeter not adequate when you consider the diverse new cyber threats that appear regularly.
Zero Trust
Zero Trust starts with the premise:

  • Don’t trust anyone or anything
  • Assume compromise has happened
  • Assume there is no traditional network edge

All of the 3 leading security standards support Zero Trust:  ISO 27001, SOC 2 and NIST.  According to NIST 800-207, the key elements of Zero Trust are:

1. Continuous Verification

  • Provide access per session only for the time needed to perform the work and demand authentication for every device, user, application and network flow
  • Ensure continuous compliance to policies for both users and systems

2. Minimize the impact if a breach does occur

  • Use network segmentation to prevent spread
  • Always use the least privilege principle only providing users or system accounts enough rights to their task

3. Automate Monitoring, Collection of Information and Response Taking a Holistic View

  • Monitor continuously security throughout all layers: users, endpoints, network, applications, cloud
  • Monitor continuously user behavior: logins, unusual activities
  • Monitor workloads, data sources
  • Collect threat intelligence
  • Automate analysis and alerts and ensure reviews
  • Automate responses such as preventing a user access to an application, isolating suspected endpoint or disabling accounts
  • Implement dynamic policies by assessing risks and modifying for users, devices, etc.
