+description:
+  - Manages Signature Sets on ASM policy.
+version_added: 2.8
+options:
+  name:
+    description:
+      - Specifies the name of the signature sets to apply/remove to the ASM policy.
+      - Apart from built-in signature sets that ship with the device, users can create and use
+        their own signature sets.
+      - When C(All Response Signatures), configures all signatures in the attack signature
+        pool that can review responses.
+      - When C(All Signatures), configures all attack signatures in the attack signature pool.
+      - When C(Apache Struts Signatures), configures signatures that target attacks against
+        the Apache Struts web servers. Only available in version 13.x and up.
+      - When C(Apache Tomcat Signatures), configures signatures that target attacks against
+        the Apache Tomcat web servers. Only available in version 13.x and up.
+      - When C(Cisco Signatures), configures signatures that target attacks against Cisco systems.
+        Only available in version 13.x and up.
+      - When C(Command Execution Signatures), configures signatures involving attacks perpetrated by executing commands.
+      - When C(Cross Site Scripting Signatures), configures signatures that target attacks caused
+        by cross-site scripting techniques.
+      - When C(Directory Indexing Signatures), configures signatures targeting attacks that browse directory listings.
+      - When C(Generic Detection Signatures), configures signatures targeting well-known
+        or common web and application attacks.
+      - When C(HTTP Response Splitting Signatures), configures signatures targeting attacks that
+        take advantage of responses for which input values have not been sanitized.
+      - When C(High Accuracy Detection Evasion Signatures), configures signatures with a high level of accuracy
+        that produce few false positives when identifying evasion attacks. Only available in version 13.x and up.
+      - When C(High Accuracy Signatures), configures signatures with a high level of accuracy
+        that produce few false positives when identifying evasion attacks.
+      - When C(IIS and Windows Signatures), configures signatures that target attacks against IIS
+        and Windows based systems. Only available in version 13.x and up.
+      - When C(Information Leakage Signatures), configures signatures targeting attacks that are looking for system data
+        or debugging information that shows where the system is vulnerable to attack.
+      - When C(Java Servlets/JSP Signatures), configures signatures that target attacks against Java Servlets
+        and Java Server Pages (JSP) based applications. Only available in version 13.x and up.
+      - When C(Low Accuracy Signatures), configures signatures that may result in more false positives
+        when identifying attacks.
+      - When C(Medium Accuracy Signatures), configures signatures with a medium level of accuracy
+        when identifying attacks.
+      - When C(OS Command Injection Signatures), configures signatures targeting attacks
+        that attempt to run system level commands through a vulnerable application.
+      - When C(OWA Signatures), configures signatures that target attacks against
+        the Microsoft Outlook Web Access (OWA) application.
+      - When C(Other Application Attacks Signatures), configures signatures targeting miscellaneous attacks
+        including session fixation, local file access, injection attempts, header tampering,
+        and so on that could affect many applications.
+      - When C(Path Traversal Signatures), configures signatures targeting attacks that attempt to access files
+        and directories that are stored outside the web root folder.
+      - When C(Predictable Resource Location Signatures), configures signatures targeting attacks that attempt
+        to uncover hidden website content and functionality by forceful browsing, or by directory and file enumeration.
+      - When C(Remote File Include Signatures), configures signatures targeting attacks that attempt to exploit
+        a remote file include vulnerability that could enable a remote attacker to execute arbitrary commands
+        on the server hosting the application.
+      - When C(SQL Injection Signatures), configures signatures targeting attacks that attempt to insert (inject)
+        a SQL query using the input data from a client to an application.
+      - When C(Server Side Code Injection Signatures), configures signatures targeting code injection attacks
+        on the server side.
+      - When C(WebSphere signatures), configures signatures targeting attacks on many computing platforms
+        that are integrated using WebSphere including general database, Microsoft Windows, IIS,
+        Microsoft SQL Server, Apache, Oracle, Unix/Linux, IBM DB2, PostgreSQL, and XML.
+      - When C(XPath Injection Signatures), configures signatures targeting attacks that attempt to gain access
+        to data structures or bypass permissions or access when a web site uses user-supplied information
+        to construct XPath queries for XML data.
+    required: True
+  policy_name:
+    description:
+      - Specifies the name of an existing ASM policy to add or remove signature sets.
+    required: True
+  alarm:
+    description:
+      - Specifies whether the security policy logs the request data in the Statistics screen,
+        if a request matches a signature that is included in the signature set.
+    type: bool
+  block:
+    description:
+      - Effective when the security policy's enforcement mode is Blocking.
+      - Determines how the system treats requests that match a signature included in the signature set.
+      - When C(yes) the system blocks all requests that match a signature,
+        and provides the client with a support ID number.
+      - When C(no) the system accepts those requests.
+    type: bool
+  learn:
+    description:
+      - Specifies if the security policy learns all requests that match a signature
+        that is included in the signature set.
+    type: bool
+  state:
+    description:
+      - When C(present), ensures that the resource exists.
+      - When C(absent), ensures the resource is removed.
+    default: present
+    choices:
+      - present
+      - absent
+  partition:
+    description:
+      - This parameter is only used when identifying ASM policy.
+    default: Common
+notes:
+  - This module is primarily used as a component of configuring ASM policy in Ansible Galaxy ASM Policy Role.
