Because truly secure systems are not yet an achievable goal, we must be able to trace a security breach to a responsible party. systems must keep records of their activities to permit later forensic analysis to trace security breaches or to aid in transaction disputes. This section outlines the core principles that form the foundation of designing secure software, derived from decades of real world experience in both defensive and offensive computer security. You’ll find many different types and definitions of computer security (e.g. information security, network security, application security, etc.). these exact definitions are less important to us.
