We're committed to practicing role minimization, ensuring that access rights align tightly with a user's job functions. Regular access reviews help to identify and rectify any unnecessary permissions that may have been granted inadvertently.

  • Role-Based Access Control (RBAC): Assigns permissions based on job role rather than individual discretion.
  • Principle of Least Privilege (PoLP): Limits user access to the bare minimum needed to accomplish their tasks.
  • Access Reviews: Conduct periodic audits to ensure access rights remain appropriate over time.
  • Segregation of Duties (SoD): Divides critical tasks among multiple individuals to prevent fraud and errors.

Regularly Update Security Protocols

We must consistently refresh our security protocols to guard against emerging cyber threats. Cybercriminals are always evolving their tactics, and we can't afford to fall behind. That's why patch management is central to our security strategy. By keeping software and systems up-to-date with the latest security updates, we're patching vulnerabilities that could be exploited.

Patch management isn't just about applying updates; it's about doing so in a timely and methodical way. We prioritize updates based on the level of threat they mitigate, ensuring the most critical patches are applied first.
