To save time a company that is developing a new vpn solution - CompTIA CAS-005

Question

To save time, a company that is developing a new VPN solution has decided to use the OpenSSL library within its proprietary software. Which of the following should the company consider to maximize risk reduction from vulnerabilities introduced by OpenSSL?

Answers
  1. correct
Explanation

The correct answer is: D. Implement an ongoing, third-party software and library review and regression testing.

Using third-party libraries like OpenSSL introduces potential vulnerabilities that must be managed proactively. The best way to maximize risk reduction is by implementing a continuous process for reviewing, testing, and updating the third-party library:

  1. Ongoing reviews: Regularly monitor for updates, patches, and disclosed vulnerabilities in the OpenSSL library.
  2. Regression testing: Ensure that any changes or updates to the library or its integration with proprietary software do not introduce new vulnerabilities or break existing functionality.
  3. Proactive management: Incorporate a third-party review to evaluate library security practices and adherence to standards.

This approach ensures that vulnerabilities are identified and mitigated promptly while maintaining compatibility with the company's proprietary software.

Why the other options are incorrect:

Include stable, long-term releases of third-party libraries instead of using newer versions:

  • Incorrect: While stable, long-term releases reduce the likelihood of bugs, they may not include the latest security patches or performance improvements, which increases the risk of using outdated libraries.

Ensure the third-party library implements the TLS and disable weak ciphers:

  • Incorrect: Ensuring strong cryptographic settings (e.g., TLS with strong ciphers) is important but does not address vulnerabilities that may exist in the OpenSSL library itself.

Compile third-party libraries into the main code statically instead of using dynamic loading:

  • Incorrect: Static linking reduces runtime dependencies but can make patching more difficult since the library is embedded in the code. This approach does not maximize risk reduction from OpenSSL vulnerabilities.
