Add a new exceptions security profile

Create Cortex XSIAM exceptions security profiles for legacy endpoint policies.

You can configure exceptions that apply to specific groups of endpoints or you can add a global endpoint policy exception.

Important

Starting with version 1.3, Cortex XSIAM enables you to manage the exception security rules from a central location and easily apply them across multiple profiles in the Legacy Agent Exceptions management page.

To manage the exceptions from Exception Configuration, you must first migrate your existing exceptions configured via the exceptions security profiles.

To create new exception security profile rules using the Legacy Agent Exceptions management page, see Add a legacy exception rule for endpoints.

If you don't migrate the legacy exceptions, you can continue to create exceptions as described below.

How to create an endpoint-specific exception

1. Add a new profile.

   1. From Cortex XSIAM, select Inventory → Endpoints → Policy Management → Prevention → Profiles → +Add Profile and select whether to Create New or Import from File a new profile.

      Note

      New imported profiles are added and not replaced.
   2. Select the platform to which the profile applies and Exceptions as the profile type.
   3. Click Next.
2. Define the basic settings.

   1. Select a unique Profile Name to identify the profile. The name can contain only letters, numbers, or spaces, and must be no more than 30 characters. The name will be visible from the list of profiles when you configure a policy rule.
   2. To provide additional context for the purpose or business reason for creating the profile, specify a profile Description. For example, you might include a case identification number or a link to a help desk ticket.
3. Configure the exceptions profile.

Configure a process exception

1. Select the operating system.
2. Enter the process name.
3. Select the endpoint protection modules that allow the process to run.

   • Select All to apply the exception across all security modules.
   • Select Disable Injection to apply the exception across these exploit modules: APC Guard, CPL Execution Protection, DEP, DLL Hijacking Protection, DLL Security, EPM D02, Exception Heap Spray Check, Exception SysExist Check, Exploit Kit Fingerprinting Protection, Font Protection, Hot Patch Protection, JIT Mitigation, Library Preallocation, Memory Limit Heap Spray Check, Null Dereference Protection, Password Theft Protection, ROP Mitigation, SEH Protection, Shellcode Preallocation, and UASLR.
4. Click the adjacent arrow.
5. After adding all processes, select Create.

You can later edit these settings from the Process Execution profile.

Configure a support exception

1. Import the JSON file from Palo Alto Networks Support. Browse for it or drag it onto the page.
2. Click Create.

Configure module-specific exceptions for the selected profile platform

• Behavioral Threat Protection Rule Exception: Right-click a Behavioral Threat alert and select Create alert exception. Review the platform and rule name. Select CGO hash, CGO signer, CGO process path, or CGO command arguments as needed. Select Profile from Exception Scope, then click Create.
• Digital Signer Exception: Right-click a Digital Signer Restriction issue and select Create issue exception. Set Exception Scope to Profile, select the exception profile name, then click Add.
• Java Deserialization Exception: Right-click a benign Suspicious Input Deserialization issue and select Create issue exception. Set Exception Scope to Profile, select the exception profile name, then click Add.
• Local File Threat Examination Exception: Right-click a PHP file issue and select Create issue exception. Set Exception Scope to Profile, select the exception profile name, then click Add.
• Gatekeeper Enhancement Exception: Right-click the issue and select Create issue exception. Set Exception Scope to Profile, select the exception profile name, then click Add. This keeps enforcement active for other child processes.

At any point, click the Generating Issue ID to return to the issue that generated the exception. You cannot edit module-specific exceptions.

1. Apply profiles to endpoints.

   To remove an exceptions profile, go to the Profiles page, right-click the profile, then select Delete.
