set appfw settings

Modifies the global application firewall settings. The global settings apply to all application firewall profiles.

Synopsys

set appfw settings [-defaultProfile <string>] [-undefAction <string>] [-sessionTimeout <positive_integer>] [-learnRateLimit <positive_integer>] [-sessionLifetime <positive_integer>] [-sessionCookieName <string>] [-clientIPLoggingHeader <string>] [-importSizeLimit <positive_integer>] [-signatureAutoUpdate ( ON | OFF )] [-signatureUrl <expression>] [-cookiePostEncryptPrefix <string>] [-logMalformedReq ( ON | OFF )] [-CEFLogging ( ON | OFF )] [-entityDecoding ( ON | OFF )] [-useConfigurableSecretKey ( ON | OFF )]

Arguments

defaultProfile

Profile to use when a connection does not match any policy. Default setting is APPFW_BYPASS, which sends unmatched connections back to the NetScaler appliance without attempting to filter them further.

Default value: AS_ENGINESETTINGS_DEFAULT_PROF_DEFAULT

undefAction

Profile to use when an application firewall policy evaluates to undefined (UNDEF).

An UNDEF event indicates an internal error condition. The APPFW_BLOCK built-in profile is the default setting. You can specify a different built-in or user-created profile as the UNDEF profile.

Default value: AS_ENGINESETTINGS_UNDEF_PROF_DEFAULT

sessionTimeout

Timeout, in seconds, after which a user session is terminated. Before continuing to use the protected web site, the user must establish a new session by opening a designated start URL.

Default value: AS_ENGINESETTINGS_SESSIONTIMEOUT_DEFAULT

Minimum value: 1

Maximum value: 65535

learnRateLimit

Maximum number of connections per second that the application firewall learning engine examines to generate new relaxations for learning-enabled security checks. The application firewall drops any connections above this limit from the list of connections used by the learning engine.

Default value: AS_ENGINESETTINGS_LEARN_RATE_LIMIT_DEFAULT

Minimum value: 1

Maximum value: 1000

sessionLifetime

Maximum amount of time (in seconds) that the application firewall allows a user session to remain active, regardless of user activity. After this time, the user session is terminated. Before continuing to use the protected web site, the user must establish a new session by opening a designated start URL.

Default value: AS_ENGINESETTINGS_SESSIONLIFETIME_DEFAULT

Maximum value: 2147483647

sessionCookieName

Name of the session cookie that the application firewall uses to track user sessions.

Must begin with a letter or number, and can consist of from 1 to 31 letters, numbers, and the hyphen (-) and underscore (_) symbols.

The following requirement applies only to the NetScaler CLI:

If the name includes one or more spaces, enclose the name in double or single quotation marks (for example, "my cookie name" or 'my cookie name').

Default value: NS_S_AS_DEFAULT_COOKIE_NAME

clientIPLoggingHeader

Name of an HTTP header that contains the IP address that the client used to connect to the protected web site or service.

importSizeLimit

Cumulative total maximum number of bytes in web forms imported to a protected web site. If a user attempts to upload files with a total byte count higher than the specified limit, the application firewall blocks the request.

Default value: AS_ENGINESETTINGS_IMPORTSIZELIMIT_DEFAULT

Minimum value: 1

Maximum value: 134217728

signatureAutoUpdate

Flag used to enable/disable auto update signatures

Possible values: ON, OFF

Default value: OFF

signatureUrl

URL to download the mapping file from server

Default value: AS_ENGINESETTINGS_SIGNATURES_UPDATE_URL

cookiePostEncryptPrefix

String that is prepended to all encrypted cookie values.

Default value: NS_S_AS_DEFAULT_CKI_POST_ENCRYPT_PREFIX

logMalformedReq

Log requests that are so malformed that application firewall parsing doesn't occur.

Possible values: ON, OFF

Default value: ON

CEFLogging

Enable CEF format logs.

Possible values: ON, OFF

Default value: OFF

entityDecoding

Transform multibyte (double- or half-width) characters to single width characters.

Possible values: ON, OFF

Default value: OFF

useConfigurableSecretKey

Use configurable secret key in AppFw operations

Possible values: ON, OFF

Default value: OFF

unset appfw settings

Use this command to remove appfw settings settings.Refer to the set appfw settings command for meanings of the arguments.
