CompTIA Updated CAS-004 Exam Questions and Answers by jannah

HTTP Strict Transport Security (HSTS) is a web security policy mechanism that helps to protect websites against man-in-the-middle attacks such as protocol downgrade attacks and cookie hijacking. It allows web servers to declare that web browsers (or other complying user agents) should only interact with it using secure HTTPS connections, and never via the insecure HTTP protocol. Enabling HSTS would prevent attackers from redirecting users from a secure site to an unsecure or malicious one.

The scan output in line 06 indicates that OCSP Must-Staple is not supported. This vulnerability exposes the application to attacks where an attacker can exploit the trust relationship between the client and the server by forging certificate revocation statuses. When OCSP stapling is not enforced, a client cannot reliably check if a certificate has been revoked, potentially allowing attackers to exploit this gap. CASP+ discusses the importance of certificate validation mechanisms such as OCSP (Online Certificate Status Protocol) to prevent man-in-the-middle and trust-exploiting attacks.

A machine-learning-based data security service would best meet the pharmaceutical company’s requirements to discover data, monitor changes, and identify suspicious activity across thousands of independent resources in cloud object storage. Machine learning can analyze vast amounts of data, detect patterns, and alert administrators to anomalies or suspicious activities without manual intervention. Traditional file integrity monitoring or data classification might not scale well or adapt dynamically to the complexity and size of the company’s environment. CASP+ highlights the use of advanced technologies like machine learning for cloud security and monitoring.
