Blocking non-compliant SSH versions and failing certificate validations are fundamental security measures:

Block sessions when certificate validation fails

''The SSH Proxy profile should block sessions that fail certificate validation to ensure that only trusted hosts are allowed.''

Block connections using non-compliant SSH versions

Older SSH versions may have vulnerabilities or lack modern encryption algorithms.

''To enforce stronger security, block SSH sessions that use older or deprecated versions of the SSH protocol that do not comply with your security posture.''

Together, these measures minimize the risk of MITM attacks and secure SSH traffic.

To fully leverage inline cloud analysis in Advanced Threat Prevention, security profiles (e.g., anti-spyware) must be updated or newly created to enable local deep learning and inline cloud analysis models.

''To activate inline cloud analysis, update your Anti-Spyware profile to enable advanced inline detection engines, including deep learning-based models and cloud-delivered signatures.''

This ensures real-time protection from sophisticated threats beyond static signatures.

Dynamic Address Groups enable the firewall to automatically adjust security policies based on tags assigned dynamically (via log events, API, etc.). This eliminates the need for manual updates to policies when server roles or IPs change.

''Dynamic Address Groups allow you to create policies that automatically adapt to changes in the environment. These groups are populated dynamically based on tags, enabling automated security policy updates without manual intervention.''

When implementing SSL Forward Proxy decryption for outbound traffic, two key challenges that must be evaluated are:

Incomplete certificate chains: This occurs when the firewall cannot validate the entire certificate chain for a site, which may cause decryption failures.

Certificate pinning: Applications like banking apps may use certificate pinning to prevent MITM (man-in-the-middle) attacks, and these applications will break if SSL Forward Proxy is used.

''When decrypting outbound SSL traffic, you must consider incomplete certificate chains, which can cause decryption to fail if the firewall cannot validate the entire chain. Also, be aware of certificate pinning in applications that prevents decryption by rejecting forged certificates.''

Enterprise DLP Profile is specifically designed to detect and log data exfiltration attempts, including those involving confidential or sensitive data.

''Enterprise DLP logs capture incidents involving potential data exfiltration. They help identify sensitive data transfers, even in seemingly legitimate traffic.''

File Blocking and Vulnerability Protection handle files or exploit detection, while WildFire focuses on malware analysis---not direct data exfiltration.
