Ensuring security when adding new features to legacy systems is crucial to protect sensitive data and maintain system integrity.

Updating legacy systems can be a daunting task, especially when security is a top priority. To ensure new features don't compromise your system's security, consider these strategies:

• Conduct thorough code reviews: Regularly review the code for vulnerabilities and outdated practices to ensure new features are secure.

• Implement robust testing: Use automated and manual testing to identify and fix security issues before deployment.

• Stay updated on security patches: Always apply the latest security patches and updates to both the legacy system and the new features.
