Questions and Answers

What is the purpose of using static test tools for source code?

  • To ensure the code is compiled correctly
  • To minimize the size of the source code
  • To debug the source code
  • To identify and address common vulnerabilities and issues in the code (correct)

    • What are some examples of failures that can result from insufficient transport layer protection?

  • Insecure cryptographic storage
  • Use of a one-way hash without a salt
  • Hard-coded credentials and missing encryption of sensitive data (correct)
  • Improper error handling

    • What is cryptographic agility?

  • The ability to break cryptographic algorithms without recompiling
  • The ability to encrypt data using multiple overlapping algorithms
  • The ability to decrypt data without knowing the cryptographic key
  • The ability to manage specific cryptographic functions embodied in configuration files (correct)
