Abstract

Configure malware security profiles to control the actions taken by Cortex XDR agents when known malware, macros, and unknown files try to run.

Malware security profiles protect against the execution of malware including trojans, viruses, worms, and grayware. Malware security profiles serve two main purposes: to define how to treat behavior common with malware, such as ransomware or script-based attacks, and to define how to treat known malware and unknown files.

You can configure the action that Cortex XDR agents take when known malware, macros, and unknown files try to run on endpoints. By default, the Cortex XDR agent will receive the default profile that contains a pre-defined configuration for each malware protection capability supported by the platform. The default setting for each capability is shown in parentheses in the user interface. To fine-tune your malware security policy, you can override the configuration of each capability to block the malicious behavior or file, allow but report it, or disable the module.

For each setting that you override, clear the Use Default option, and select the setting of your choice.

Note

In this profile, the Report options configure the endpoints to report the corresponding suspicious files, actions, processes, or behaviors to Cortex XSIAM, without blocking them. The Disabled options configure the endpoints to neither analyze nor report the corresponding malware or behavior.

The tasks below are organized according to the operating systems used by your organization's endpoints.

  1. Add a new profile and define basic settings.

    1. From Cortex XSIAM, select EndpointsPolicy ManagementPreventionProfiles. Click +Add Profile, and select whether to create a new profile, or to import a profile from a file.

      Note

      New profiles based on imported profiles are added, and do not replace existing ones.

    2. Select the Windows platform, and Malware as the profile type.

    3. Click Next.

    4. For Profile Name, enter a unique name for 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.

    5. For Description, to provide additional context for the purpose or business reason for creating the profile, enter a profile description. For example, you might include an incident identification number or a link to a help desk ticket.

  2. Configure Portable Executable and DLL Examination. The Cortex XDR agent can analyze and prevent malicious executable files and DLL files from running on Windows endpoints.

    Note

    As part of the anti-malware security flow, the Cortex XDR agent leverages the operating system's capability to identify revoked certificates for executables, and DLL files that attempt to run on the endpoint by accessing the Windows Certificate Revocation List (CRL). To allow the Cortex XDR agent access the CRL, you must enable internet access over port 80 for Windows endpoints. If the endpoint is not connected to the internet, or you experience delays with executables and DLLs running on the endpoint, contact Customer Support.
