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.”

Protecting againstmaliciousandmisconfigured domainsrequires two critical services:

Advanced Threat Prevention

Provides signature-based and advanced analysis to identify threats, including DNS-based attacks.

“Advanced Threat Prevention enables the NGFW to detect and prevent exploits and malware-based communications, including those leveraging DNS.”

Advanced DNS Security

Specifically designed to detect and sinkhole malicious and misconfigured DNS queries.

“DNS Security uses real-time intelligence to block DNS-based threats, protect against data exfiltration, and automatically sinkhole suspicious domain lookups.”

Bycombiningthese services in security policies, NGFWs ensure robust protection against domain-based threats and misconfigurations.

To fully leverageinline cloud analysisin Advanced Threat Prevention, security profiles (e.g., anti-spyware) must beupdated or newly createdto 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 ensuresreal-time protectionfrom sophisticated threats beyond static signatures.
