Question
A security engineer is hardening existing solutions to reduce application vulnerabilities. Which of the following solutions should the engineer implement FIRST? (Choose two.)
A. Auto-update
B. HTTP headers
C. Secure cookies
D. Third-party updates
E. Full disk encryption
F. Sandboxing
G. Hardware encryption
Answer
A. Auto-update
B. HTTP headers
Explanation
To effectively harden existing solutions and reduce application vulnerabilities, a security engineer should prioritize implementing the following two solutions first:
A. Auto-update
B. HTTP headers
Auto-update is a crucial solution that ensures applications and systems are always up-to-date with the latest security patches and bug fixes. By enabling auto-update, the engineer can minimize the risk of known vulnerabilities being exploited by attackers. Keeping software up-to-date is one of the most effective ways to prevent security breaches and maintain a strong security posture.
Implementing secure HTTP headers is another essential step in hardening web applications. HTTP headers provide additional security controls and can help mitigate various web-based attacks. Some important HTTP headers to consider include:
- X-XSS-Protection: Enables browser’s built-in cross-site scripting (XSS) protection.
- X-Frame-Options: Prevents clickjacking attacks by controlling whether a page can be embedded in an iframe.
- Strict-Transport-Security (HSTS): Enforces secure HTTPS connections and prevents downgrade attacks.
- Content-Security-Policy (CSP): Defines approved sources of content and helps prevent cross-site scripting and other injection attacks.
By implementing these HTTP headers, the security engineer can add an extra layer of defense against common web application vulnerabilities and enhance the overall security posture of the application.
While the other options listed, such as secure cookies, third-party updates, full disk encryption, sandboxing, and hardware encryption, are also important security measures, prioritizing auto-update and secure HTTP headers will provide the most immediate and significant impact in reducing application vulnerabilities.
