Multiple choice technology architecture

Consider application security measures such as encryption, SSL, authentication and authorization. What is the relation between Performance and Security in an application?

  1. They are not related to each other in any way

  2. High Security generally results in high performance

  3. High performance is a pre-requisite for secure systems

  4. Security and Performance are inversely proportional

  5. Low performance systems cannot be secure

D Correct answer
Explanation

Security measures (encryption, SSL, authentication) add computational overhead, causing encryption/decryption delays, additional network round-trips for handshakes, and CPU resources for cryptographic operations. This creates an inverse relationship - increasing security generally decreases performance. High security doesn't improve performance, performance isn't a prerequisite for security, and low-performance systems can still be secure (just slower).
