The user can use theMalware Protection profileto configure malware protection in the Cortex XDR console. The Malware Protection profile defines the actions that Cortex XDR takes when it detects malware on your endpoints. You can configure different actions for different types of malware, such as ransomware, password theft, or child process. You can also configure the scan frequency and scope for periodic malware scans. The Malware Protection profile is part of the Endpoint Security policy that you assign to your endpoints.Reference:

Endpoint Security Policy

The outcome of creating and implementing an alert exclusion is that the Cortex XDR console will hide those alerts that match the exclusion criteria. An alert exclusion is a policy that allows you to filter out alerts that are not relevant, false positives, or low priority, and focus on the alerts that require your attention. When you create an alert exclusion, you can specify the criteria that define which alerts you want to exclude, such as alert name, severity, source, or endpoint. After you create an alert exclusion, Cortex XDR will hide any future alerts that match the criteria, and exclude them from incidents and search query results. However, the alert exclusion does not affect the behavior of the Cortex XDR agent or the security policy on the endpoint. The Cortex XDR agent will still create an alert for the event and apply the appropriate action, such as blocking or quarantining, according to the security policy. The alert exclusion only affects the visibility of the alert on the Cortex XDR console, not the actual protection of the endpoint.Therefore, the correct answer is B, the Cortex XDR console will hide those alerts12

To ensure that the same protection is extended to all your servers, you need to create Behavioral Threat Protection (BTP) rules to recognize and prevent the activity. BTP is a feature of Cortex XDR that allows you to create custom rules that detect and block malicious or suspicious behaviors on your endpoints, such as file execution, process injection, network connection, or registry modification. BTP rules can use various operators, functions, and variables to define the criteria and the actions for the rules.By creating BTP rules that match the behaviors of the supply chain attack, you can prevent the attack from compromising your servers12.

Let's briefly discuss the other options to provide a comprehensive explanation:

B) Enable DLL Protection on all servers but there might be some false positives: This is not the correct answer. Enabling DLL Protection on all servers will not ensure that the same protection is extended to all your servers. DLL Protection is a feature of Cortex XDR that allows you to block the execution of unsigned or untrusted DLL files on your endpoints. DLL Protection can help to prevent some types of attacks that use malicious DLL files, but it may not be effective against the supply chain attack that used a Trojanized DLL file that was digitally signed by a trusted vendor.DLL Protection may also cause some false positives, as it may block some legitimate DLL files that are unsigned or untrusted3.

C) Create IOCs of the malicious files you have found to prevent their execution: This is not the correct answer. Creating IOCs of the malicious files you have found will not ensure that the same protection is extended to all your servers. IOCs are indicators of compromise that you can create to detect and respond to known threats on your endpoints, such as file hashes, registry keys, IP addresses, domain names, or full paths. IOCs can help to identify and block the malicious files that you have already discovered, but they may not be effective against the supply chain attack that used different variants of the malicious files with different hashes or names.IOCs may also become outdated, as the attackers may change or update their files to evade detection4.

D) Enable Behavioral Threat Protection (BTP) with cytool to prevent the attack from spreading: This is not the correct answer. Enabling BTP with cytool will not ensure that the same protection is extended to all your servers. BTP is a feature of Cortex XDR that allows you to create custom rules that detect and block malicious or suspicious behaviors on your endpoints, such as file execution, process injection, network connection, or registry modification. BTP rules can help to prevent the attack from spreading, but they need to be created and configured in the Cortex XDR app, not with cytool. Cytool is a command-line tool that allows you to perform various operations on the Cortex XDR agent, such as installing, uninstalling, upgrading, or troubleshooting. Cytool does not have an option to enable or configure BTP rules.

In conclusion, to ensure that the same protection is extended to all your servers, you need to create BTP rules to recognize and prevent the activity. By using BTP rules, you can create custom and flexible prevention rules that match the behaviors of the supply chain attack.

JIT Mitigation is an Exploit Protection Module (EPM) that can be used to prevent attacks based on OS function. JIT Mitigation protects against exploits that use the Just-In-Time (JIT) compiler of the OS to execute malicious code. JIT Mitigation monitors the memory pages that are allocated by the JIT compiler and blocks any attempts to execute code from those pages. This prevents attackers from using the JIT compiler as a way to bypass other security mechanisms such as Data Execution Prevention (DEP) and Address Space Layout Randomization (ASLR).Reference:

The Broker VM is a virtual machine that acts as a data broker between third-party data sources and the Cortex Data Lake. It can ingest different types of data, such as syslog, netflow, database, and pathfinder. The Syslog Collector functionality of the Broker VM allows it to receive syslog messages from third-party devices, such as firewalls, routers, switches, and servers, and forward them to the Cortex Data Lake. The Syslog Collector can be configured to filter, parse, and enrich the syslog messages before sending them to the Cortex Data Lake. The Syslog Collector can also be used to ingest logs from third-party firewall vendors, such as Cisco, Fortinet, and Check Point, to the Cortex Data Lake. This enables Cortex XDR to analyze the firewall logs and provide visibility and threat detection across the network perimeter.Reference:
