Security Principles & Strategies

Content Leader: Jess Garcia - Last Updated: January 23, 2007

Security Parameters

  • Confidentiality
  • Integrity
  • Availability

Security Principles & Strategies

  • Principle of least privilege.
  • Defense in depth - Layered Security.
  • Limited Trust: Trust no-one, nothing.
  • “Know Yourself & Know Your Enemy”.
  • Security through obscurity.
  • Biodiversity.


  • Identify critical/most exposed assets & put your efforts on defending them.
  • Mitigate Risk.
  • Defend from inside threats.
  • Review & Audit Policies, Processes & Technologies Periodically.
  • Plan for the worse and hope for the best.
  • Anything that makes security easier, probably creates a security flaw.
  • Good security is not characteristic of a product but of a deployment.

In the Real World

  • Nothing is secure.
  • Prevention is ideal but detection is a must.
  • Paranoia is your friend.
  • You can prove that a system is not secure; you just cannot prove that it is secure.
  • Security is a trade-off with usability.
  • Defenders have to "win" every single day; Attackers only have to win once.

The Human Factor

  • Educate Your Users.
  • Risk assumed by one is shared by all.
  • Never underestimate human stupidity.
  • Don’t forget about the Political Layer


  • How secure is secure enough?
  • "Sure, I'm paranoid, but am I paranoid enough?"
