Add cookies, parameters and URLs

Add cookies

Cookie protections can be configured and managed directly within the policy editor by selecting the Cookies option.

Each cookie configuration includes:

  • Cookie Type: Explicit or Wildcard. For details on explicit and wildcard matching, see the Matching Types: Explicit vs Wildcard section.
  • Cookie Name: The name of the cookie to be monitored or protected
  • Enforcement Type:
    • Allow: Specifies that this cookie may be changed by the client. The cookie is not protected from modification
    • Enforce: Specifies that this cookie may not be changed by the client
  • Attack Signatures: Indicates whether attack signatures and threat campaigns are enabled, disabled, or not applicable
  • Mask value in logs: When enabled, the cookie’s value will be masked in the request log for enhanced security and privacy

For a complete list of configurable cookie properties and options, see the Cookie Configuration Parameters documentation under the cookies section.

Select Edit Configuration to configure cookie violations. The following violations can be configured for cookies:

  • VIOL_COOKIE_EXPIRED: Triggered when a cookie’s timestamp is expired
  • VIOL_COOKIE_LENGTH: Triggered when cookie length exceeds the configured limit
  • VIOL_COOKIE_MALFORMED: Triggered when cookies are not RFC-compliant
  • VIOL_COOKIE_MODIFIED: Triggered when domain cookies have been tampered with

For each violation type, you can:

  • Set the enforcement action
  • Toggle Alarm, Alarm and Block, or Disabled settings

For more details about enforcement modes, see the Glossary, specifically the entry: Enforcement mode.

See the Supported Violations for additional details.

  1. Choose Cookie Type:

    • Select either Explicit for exact cookie matching or Wildcard for pattern-based matching

  2. Configure Basic Properties:

    • Enter the Cookie Name
    • Choose whether to mask the cookie value in logs

  3. Set Enforcement Type:

    • Choose either Allow or Enforce

  4. Optional: Configure Attack Signatures

    • If enabled, you can overwrite attack signatures for this specific cookie
    • For details on signature configuration, refer to the documentation on Add Signature Sets

  5. Select Add Cookie to save your configuration

Add parameters

Parameter protections can be configured and managed directly within the policy editor by selecting the Parameters option.

Parameter properties and types

Each parameter configuration includes:

  • Parameter Type: Explicit or Wildcard. For details on explicit and wildcard matching, see the Matching Types: Explicit vs Wildcard section.
  • Parameter Name: The name of the parameter
  • Location: Where the parameter is expected (URL query string, POST data, etc.)
  • Value Type: The expected type of the parameter value (e.g., alpha-numeric, integer, email)
  • Attack Signatures: Whether attack signature checking is enabled for this parameter
  • Mask value in logs: When enabled, the parameter’s value will be masked in the request log for enhanced security and privacy. This sets sensitiveParameter property of the parameter item.

For a complete list of configurable parameter properties and options, see the Parameter Configuration Parameters documentation under the parameters section.

Parameter violations

Select Edit Configuration to configure parameter violations. The following violations can be configured for parameters:

  • VIOL_PARAMETER: Triggered when an illegal parameter is detected
  • VIOL_PARAMETER_ARRAY_VALUE: Triggered when an array parameter value is illegal
  • VIOL_PARAMETER_DATA_TYPE: Triggered when parameter data type doesn’t match configured security policy
  • VIOL_PARAMETER_EMPTY_VALUE: Triggered when a parameter value is empty but shouldn’t be
  • VIOL_PARAMETER_LOCATION: Triggered when a parameter is found in wrong location
  • VIOL_PARAMETER_MULTIPART_NULL_VALUE: Triggered when the multi-part request has a parameter value that contains the NULL character (0x00)
  • VIOL_PARAMETER_NAME_METACHAR: Triggered when illegal meta characters are found in parameter name
  • VIOL_PARAMETER_NUMERIC_VALUE: Triggered when numeric parameter value is outside allowed range
  • VIOL_PARAMETER_REPEATED: Triggered when a parameter name is repeated illegally
  • VIOL_PARAMETER_STATIC_VALUE: Triggered when a static parameter value doesn’t match configured security policy
  • VIOL_PARAMETER_VALUE_BASE64: Triggered when the value is not a valid Base64 string
  • VIOL_PARAMETER_VALUE_LENGTH: Triggered when parameter value length exceeds limits
  • VIOL_PARAMETER_VALUE_METACHAR: Triggered when illegal meta characters are found in parameter value
  • VIOL_PARAMETER_VALUE_REGEXP: Triggered when parameter value doesn’t match required pattern

For each violation type, you can:

  • Set the enforcement action
  • Toggle Alarm, Alarm and Block, or Disabled settings

For more details about enforcement modes, see the Glossary, specifically the entry: Enforcement mode.

See the Supported Violations for additional details.

Add a parameter to your policy

  1. Choose Parameter Type:

    • Select either Explicit for exact parameter matching or Wildcard for pattern-based matching

  2. Configure Basic Properties:

    • Enter the parameter Parameter Name
    • Select the Location where the parameter is expected
    • Choose the Value Type (alpha-numeric, integer, email, etc.)
    • Set the Data Type if applicable

  3. Set Security Options:

    • Choose whether to enable attack signatures
    Attack Signatures are only applicable when the Value Type is User Input or Array and the Data Type is either Alphanumeric or Binary

  4. Optional: Configure Attack Signatures

    • If enabled, you can overwrite attack signatures for this specific parameter
    • For details on signature configuration, refer to the documentation on Add Signature Sets

  5. Select Add Parameter to save your configuration

Add URLs

URL protections can be configured and managed directly within the policy editor by selecting the URLs option.

URL properties and types

Each URL configuration includes:

  • URL Type: Explicit or Wildcard. For details on explicit and wildcard matching, see the Matching Types: Explicit vs Wildcard section.

  • Enforcement Type:
    • Allow: Permits access to the URL with optional attack signature checks
    • Disallow: Blocks access to the URL entirely
  • Attack Signatures: Indicates whether attack signatures and threat campaigns are enabled, disabled, or not applicable
⚠️ Important: Attack Signatures are automatically shown as "Not Applicable" when Enforcement Type is set to Disallow since the URL is explicitly blocked and signature checking is unnecessary.

For a complete list of configurable URL properties and options, see the URL Configuration Parameters documentation under the urls section.

URL violations

Select Edit Configuration to configure URL violations. The following violations can be configured for URLs:

  • VIOL_URL: Triggered when an illegal URL is accessed
