When the ProxySG processes installed policy, how does it handle a rule that contains a syntax error?

When the ProxySG processes installed policy, if it encounters a rule that contains a syntax error, it flags the error during the compilation stage and does not install the rule. This is crucial because rules with syntax errors could lead to unexpected behavior or compromise the security and functionality of the proxy. By failing to install a rule that cannot be correctly interpreted, the system ensures that only properly defined rules are implemented, maintaining integrity in the policy configuration. This prevents any potential misuse or vulnerabilities that could arise from a faulty policy.

In system operation, compiling the rules and identifying errors before installation ensures that administrators can address any issues before the rules are actively applied, promoting stable and secure policy management.
