Add a New Agent Settings Profile
Agent Settings Profiles enable you to customize Cortex XDR agent settings for different platforms and groups of users.
Agent Settings Profiles enable you to customize Cortex XDR agent settings for different platforms and groups of users.
- Add a new profile.
- From Cortex XDR, select.EndpointsPolicy ManagementProfiles+ New Profile
- Select the platform to which the profile applies andAgent Settingsas the profile type.
- Define the basic settings.
- Enter a uniqueProfile Nameto identify the profile. The name can contain only letters, numbers, or spaces, and must be no more than 30 characters. The name you choose will be visible from the list of profiles when you configure a policy rule.
- To provide additional context for the purpose or business reason that explains why you are creating the profile, enter a profileDescription. For example, you might include an incident identification number or a link to a help desk ticket.
- (Windows, Mac, and Linux only) Configure theDisk Spaceto allot for Cortex XDR agent logs.Specify a value in MB from 100 to 10,000 (default is 5,000).
- (Windows and Mac only) ConfigureUser Interfaceoptions for the Cortex XDR console.By default, Cortex XDR uses the settings specified in the default agent settings profile and displays the default configuration in parenthesis. When you select a setting other than the default, you override the default configuration for the profile.
- Tray Icon—Choose whether you want the Cortex XDR agent icon to beVisible(default) orHiddenin the notification area (system tray).
- XDR Agent Console Access—Enable this option to allow access to the Cortex XDR console.
- XDR Agent User Notifications—Enable this option to operate display notifications in the notifications area on the endpoint. When disabled, the Cortex XDR agent operates in silent mode where the Cortex XDR agent does not display any notifications in the notification area. If you enable notifications, you can use the default notification messages, or provide custom text for each notification type. You can also customize a notification footer.
- Live Terminal User Notifications—Choose whether toNotifythe end user and display a pop-up on the endpoint when you initiate a Live Terminal session. For Cortex XDR agents 7.3 and later releases only, you can choose toRequest end-user permissionto start the session. If the end user denies the request, you will not be able to initiate a Live Terminal session on the endpoint.
- (Cortex XDR agent 7.3 and later releases only)Live Terminal Active Session Indication—Enable this option to display a blinking light ( ) on the tray icon (or in the status bar for Mac endpoints) for the duration of the remote session to indicate to the end user that a live terminal session is in progress.
- (Android only) Configure network usage preferences.When the option toUpload Using Cellular Datais enabled, the Cortex XDR agent uses cellular data to send unknown apps to the Cortex XDR for inspection. Standard data charges may apply. When this option is disabled, the Cortex XDR agent queues any unknown files and sends them when the endpoint connects to a Wi-Fi network. If configured, the data usage setting on the Android endpoint takes precedence over this configuration.
- (Windows and Mac only) ConfigureAgent Securityoptions that prevent unauthorized access or tampering with the Cortex XDR agent components.Use the default agent settings or customize them for the profile. To customize agent security capabilities:
- EnableXDR Agent Tampering Protection.
- (Windows only) By default, the Cortex XDR agent protects all agent components, however you can configure protection more granularly for Cortex XDR agent services, processes, files, and registry values. With Traps 5.0.6 and later releases, when protection is enabled, access will be read-only. In earlier Traps releases, enabling protection disables all access to services, processes, files, and registry values.
- (Windows and Mac only) Set anUninstall Password.Define and confirm a password the user must enter to uninstall the Cortex XDR agent. The uninstall password is encrypted using encryption algorithm (PBKDF2) when transferred between Cortex XDR and Cortex XDR agents. Additionally, the uninstall password is used to protect tampering attempts when using Cytool commands.The default uninstall password isPassword1. A new password must satisfy thePassword Strengthindicator requirements:
- Contain eight or more characters.
- Contain English letters, numbers, or any of the following symbols:!()-._`~@#"'.
- (Windows only) ConfigureWindows Security Center Integration.The Windows Security Center is a reporting tool that monitors the system health and security state of Windows endpoints on Windows 7 and later releases:
When youEnablethe Cortex XDR agent to register to the Windows Security Center, Windows shuts down Microsoft Defender on the endpoint automatically. If you still want to allow Microsoft Defender to run on the endpoint where Cortex XDR is installed, you must Disable this option. However, Palo Alto Networks does not recommend running Windows Defender and the Cortex XDR agent on the same endpoint since it might cause performance issues and incompatibility issues with Global Protect and other applications.
- Enabled—The Cortex XDR agent registers with the Windows Security Center as an official Antivirus (AV) software product. As a result, Windows shuts down Microsoft Defender on the endpoint automatically, except for endpoints that are running Windows Server versions. To avoid performance issues, Palo Alto Networks recommends that you disable or remove Windows Defender from endpoints that are running Windows Server versions and where the Cortex XDR agent is installed.
- Enabled (No Patches)—For the Cortex XDR agent 5.0 release only, select this option if you want to register the agent to the Windows Security Center but prevent from Windows to automatically install Meltdown/Spectra vulnerability patches on the endpoint.
- Disabled—The Cortex XDR agent does not register to the Windows Action Center. As a result, Windows Action Center could indicate that Virus protection is Off, depending on other security products that are installed on the endpoint.
- (Windows and Mac only)Response Actions.If you need to isolate an endpoint but want to allow access for a specific application , add the process to theNetwork Isolation Allow List. The following are considerations to the allow list:
- When you add a specific application to your allow list from network isolation, the Cortex XDR agent continues to block some internal system processes. This is because some applications, for example ping.exe, can use other processes to facilitate network communication. As a result, if the Cortex XDR agent continues to block an application you included in your allow list, you may need to perform additional network monitoring to determine the process that facilitates the communication, and then add that process to the allow list.
- (Windows) For VDI sessions, using the network isolation response action can disrupt communication with the VDI host management system thereby halting access to the VDI session. As a result, before using the response action you must add the VDI processes and corresponding IP addresses to your allow list.
- +Addan entry to the allow list.
- Specify theProcess Pathyou want to allow and theIPv4orIPv6address of the endpoint. Use the*wildcard on either side to match any process or IP address. For example, specify*as the process path and an IP address to allow any process to run on the isolated endpoint with that IP address. Conversely, specify*as the IP address and a specific process path to allow the process to run on any isolated endpoint that receives this profile.
- Click the check mark when finished.
- (Supported on Cortex XDR agent 7.0 or a later for Windows endpoints and Cortex XDR agent 7.3 or later for Mac and Linux endpoints) Specify theContent Configurationfor your Cortex XDR agents.
If you disable or delay automatic-content updates provided by Palo Alto Networks, it may affect the security level in your organization.
- Content Auto-update—By default, the Cortex XDR agent always retrieves the most updated content and deploys it on the endpoint so it is always protected with the latest security measures. However, you canDisablethe automatic content download. Then, the agent stops retrieving content updates from the Cortex XDR Server and keeps working with the current content on the endpoint.
- If you disable content updates for a newly installed agent, the agent will retrieve the content for the first time from Cortex XDR and then disable content updates on the endpoint.
- When you add a Cortex XDR agent to an endpoints group with disabled content auto-upgrades policy, then the policy is applied to the added agent as well.
- Content Rollout—The Cortex XDR agent can retrieve content updatesImmediatelyas they are available, or after a pre-configuredDelayedperiod. When you delay content updates, the Cortex XDR agent will retrieve the content according to the configured delay. For example, if you configure a delay period of two days, the agent will not use any content released in the last 48 hours.
- EnableAgent Auto Upgradefor your Cortex XDR agents.To ensure your endpoints are always up-to-date with the latest Cortex XDR agent release, enable automatic agent upgrades. For increased flexibility, you can choose to apply automatic upgrades to major releases only, to maintenance releases only, or to both. It can take up to 15 minutes for new and updated auto-upgrade profile settings to take effect on your endpoints. To control the agent auto upgrade scheduler and number of parallel upgrades in your network, see Configure Global Agent Settings.Automatic upgrades are not supported with non-persistent VDI and temporary sessions.
- (Supported on Cortex XDR agent 7.0 or a later for Windows endpoints and Cortex XDR agent 7.3 or later for Mac and Linux endpoints) Specify theDownload Sourcefor agent and content updates.To reduce your external network bandwidth loads during updates, you can choose theDownload Source(s)from which the Cortex XDR agent retrieves agent release upgrades and content updates: from a peer agent in the local network, from the Palo Alto Networks Broker VM, or directly from the Cortex XDR server. If all options are selected in your profile, then the attempted download order is first using P2P, then from Broker VM, and lastly from the Cortex Server.
Limitations in the content download process:
- (Requires Cortex XDR agents 7.4 and later for P2P agent upgrade)P2P—Cortex XDR deploys serverless peer-to-peerP2Pdistribution to Cortex XDR agents in your LAN network by default. Within the six hour randomization window during which the Cortex XDR agent attempts to retrieve the new version, it will broadcast its peer agents on the same subnet twice: once within the first hour, and once again during the following five hours. If the agent did not retrieve the files from other agents in both queries, it will proceed to the next download source defined in your profile.To enable P2P, you must enable UDP and TCP over the definedPORTinDownload Source. By default, Cortex XDR uses port 33221. You can configure another port number.
- (Requires Cortex XDR agents 7.4 and later releases and Broker VM 12.0 and later)Broker VM—If you have a Palo Alto Networks Broker VM in your network, you can leverage the Local Agent Settings applet to cache release upgrades and content updates. When enabled and configured, the Broker retrieves from Cortex XDR the latest installers and content every 15 minutes and stores them for a 30-days retention period since an agent last asked for them. If the files were not available on the Broker VM at the time of the ask, the agent proceeds to download the files directly from the Cortex XDR server.If you enable the Broker download option, proceed to select one or more available brokers from the list. Cortex XDR enables you to select only brokers that are connected and for which the caching is configured. When you select multiple brokers, the agent chooses randomly which broker to use for each download request.
- Cortex Server—To ensure your agents remain protected, theCortex Serverdownload source is always enabled to allow all Cortex XDR agents in your network to retrieve the content directly from the Cortex XDR server on their following heartbeat.
- When you install the Cortex XDR agent, the agent retrieves the latest content update version available. A freshly installed agent can take between five to ten minutes (depending on your network and content update settings) to retrieve the content for the first time. During this time, your endpoint is not protected.
- When you upgrade a Cortex XDR agent to a newer Cortex XDR agent version, if the new agent cannot use the content version running on the endpoint, then the new content update will start within one minute in P2P and within five minutes from Cortex XDR.
- EnableNetwork Location Configurationfor your Cortex XDR agents.(Requires Cortex XDR agents 7.1 and later releases) If you configure host firewall rules in your network, you must enable Cortex XDR to determine the network location of your device, as follows:
If the Cortex XDR agent detects a network change on the endpoint, the agent triggers the device location test, and re-calculates the policy according to the new location.
- A domain controller (DC) connectivity test— WhenEnabled, the DC test checks whether the device is connected to the internal network or not. If the device is connected to the internal network, then it is in the organization. Otherwise, if the DC test failed or returned an external domain, Cortex XDR proceeds to a DNS connectivity test.
- A DNS test—In the DNS test, the Cortex XDR agent submits a DNS name that is known only to the internal network. If the DNS returned the pre-configured internal IP, then the device is within the organization. Otherwise, if the DNS IP cannot be resolved, then the device is located elsewhere. Enter theIP AddressandDNS Server Namefor the test.
