Using mod_rewrite to read/write stdin/stdout from an external program like this: ProxyRequests on If the Base64 violation occurs in the header, the system suggests disabling the violation orĭisabling the Base64 decoding for that header.I figured it out. Mandatory is missing, the system suggests disabling the violation or making the missing header If signature violations occur in the header, the system suggests disabling the signature thatĬause the violation, or disabling the signature check for that header. Header violation is a false positive, you can also disable normalization from the Evasion You can drill down and view the headers causing violations. If they are false positives, you can consider turning off evasion violations or You can examine the requests to see if they are legitimate or false HTTP header violations are listed under Evasion Techniques in the section Evasion Techniquesĭetected in Headers.

You can review suggestions related to violations that occur on the Traffic Learning screen. Request header matches one of the headers, the system performs the configured options for that Header to see if it matches any of the HTTP headers other than the wildcard header. When Application Security Manager™ receives requests, the system checks the Normalizing the header, select the Evasion Techniques

If you want evasion violations to be issued in case of problems while.

HTML, hex, and decimal codes, and other HTML extras. This option removes non-printable characters, comment delimiters, Which require backslash replacement or path parameter removal. That may include URLs with multiple slashes, directory traversal, or This option normalizes URLs in referer headers or custom headers Included in URL normalization and thus is not available when checking Include strings with encoded percent codes (%xx) that replace certainĬharacters, perform unescaping, and require other checks.

This option normalizes referer headers or custom headers that may

If you want to normalize this header, select the options you need.

Illegal Base64 Value violation occurs (if set to alarm or block). The system performs decoding on the header and if decoding fails, the You cannot delete any of the default HTTP headers. Normalization on the authorization header may impact performance. Therefore, the Base64ĭecoding check box is unavailable for this header. Generic Base64 setting should always be off.

ASM™ detects what and when to decode, so the This header the reason for this is that the user name (and password) are only part of theĪuthorization header value. YouĬannot change the settings, but you can configure the settings of a specific cookie byĪlthough the user name may be encoded as Base64, the Base64 decoding is always off for The other settings are not typically relevant for this header.Ĭookies have their own process for normalization and attack signature check and so theĬookie as a header is always excluded from the normalization and attack signature check. Violations are issued if problems are encountered during normalization. The system checks signatures against them, performs URL normalization, and validates the URL syntax. When requests have referer headers, they include URLs. The Base64 Decoding and Mandatory check boxes are unavailable for this header. Realize that enabling normalization on the wildcard header may impact performance. No normalization settings are selected by default, but you can edit them. This wildcard HTTP header checks signatures against all requests unless they match another HTTP header.
