Question 620
At Harborview Biotechnology, the FortiGate 7.6 security administration team encounters the following authorized operational case: FortiGate continues to trust an obsolete internal intermediate after the issuing CA changes, causing inconsistent SSL inspection results. They need a defensible FortiOS configuration, diagnosis, validation or prevention decision. Which recurring review is most relevant to the same root risk?
Explanation
Correct Answer
Synchronize inspection trust stores with PKI lifecycle changes. This recurring practice addresses expired intermediate after ca rotation because certificate verification depends on an up-to-date chain rather than just the hostname or leaf validity. It reinforces the supported change to replace obsolete issuing-chain references and test new certificates end to end rather than relying on an unrelated periodic audit.
Incorrect Answers
Audit profile references for every VLAN internet rule reduces recurrence of web filter profile not applied, rather than the observed expired intermediate after ca rotation issue. The relevant preventive control for Harborview Biotechnology is: Synchronize inspection trust stores with PKI lifecycle changes. This distinction matters because certificate verification depends on an up-to-date chain rather than just the hostname or leaf validity.
Test both direct and proxied paths after client configuration changes reduces recurrence of https explicit proxy browser access, rather than the observed expired intermediate after ca rotation issue. The relevant preventive control for Harborview Biotechnology is: Synchronize inspection trust stores with PKI lifecycle changes. This distinction matters because certificate verification depends on an up-to-date chain rather than just the hostname or leaf validity.
Retain web-filter logs with relevant category and rule fields reduces recurrence of web-filter log category evidence, rather than the observed expired intermediate after ca rotation issue. The relevant preventive control for Harborview Biotechnology is: Synchronize inspection trust stores with PKI lifecycle changes. This distinction matters because certificate verification depends on an up-to-date chain rather than just the hostname or leaf validity.
