TheHost Insights moduleprovides the best visibility to view vulnerabilities on your endpoints. The Host Insights module is an add-on feature for Cortex XDR that combines vulnerability management, application and system visibility, and a Search and Destroy feature to help you identify and contain threats. The vulnerability management feature allows you to scan your Windows endpoints for known vulnerabilities and missing patches, and view the results in the Cortex XDR console. You can also filter and sort the vulnerabilities by severity, CVSS score, CVE ID, or patch availability. The Host Insights module helps you reduce your exposure to threats and improve your security posture.Reference:

The Broker VM for Cortex XDR is a virtual machine that serves as the central communication hub for all Cortex XDR agents deployed in your organization. It enables agents to communicate with the Cortex XDR cloud service and allows you to manage and monitor the agents' activities from a centralized location. The system requirements for the Broker VM are as follows:

CPU: 4 cores

RAM: 8 GB

Disk space: 256 GB

Network: Internet access and connectivity to all Cortex XDR agents

The disk space requirement is based on the number of agents and the frequency of content updates. The Broker VM stores the content updates locally and distributes them to the agents. The disk space also depends on the retention period of the content updates, which can be configured in the Broker VM settings. The default retention period is 30 days.

You can star security events in Cortex XDR in two ways: manually star an alert or an incident, or create an alert-starring or incident-starring configuration. Starring security events helps you prioritize and track the events that are most important to you. You can also filter and sort the events by their star status in the Cortex XDR console.

To manually star an alert or an incident, you can use the star icon in the Alerts table or the Incidents table. You can also star an alert from the Causality View or the Query Center Results table. You can star an incident from the Incident View or the Query Center Results table. You can also unstar an event by clicking the star icon again.

To create an alert-starring or incident-starring configuration, you can use the Alert Starring Configuration or the Incident Starring Configuration pages in the Cortex XDR console. You can define the criteria for starring alerts or incidents based on their severity, category, source, or other attributes. You can also enable or disable the configurations as needed.

To manually upgrade the Cortex XDR agents, you can use theAsset Managementpage or theEndpoint Administrationpage in the Cortex XDR console. On the Asset Management page, you can select one or more endpoints and clickActions > Upgrade Agent. On the Endpoint Administration page, you can select one or more agent versions and clickUpgrade. You can also schedule automatic agent upgrades using theAgent Installationspage.Reference:

Ransomware is a type of malicious software, or malware, that encrypts certain files or data on the victim's system or network and prevents them from accessing their data until they pay a ransom. This is by far the most common tactic used by ransomware to shut down a victim's operation, as it can cause costly disruptions, data loss, and reputational damage. Ransomware can affect individual users, businesses, and organizations of all kinds. Ransomware can spread through various methods, such as phishing emails, malicious attachments, compromised websites, or network vulnerabilities. Some ransomware variants can also self-propagate and infect other devices or networks. Ransomware authors typically demand payment in cryptocurrency or other untraceable methods, and may threaten to delete or expose the encrypted data if the ransom is not paid within a certain time frame. However, paying the ransom does not guarantee that the files will be decrypted or that the attackers will not target the victim again.Therefore, the best way to protect against ransomware is to prevent infection in the first place, and to have a backup of the data in case of an attack1234

Answer : C

The ultimate goal of any exploit is to reach the kernel, which is the core component of the operating system that has the highest level of privileges and access to the hardware resources. Application exploits are attacks that target vulnerabilities in specific applications, such as web browsers, email clients, or office suites. Kernel exploits are attacks that target vulnerabilities in the kernel itself, such as memory corruption, privilege escalation, or code execution. Kernel exploits are more difficult to prevent and detect than application exploits, because they can bypass security mechanisms and hide their presence from the user and the system.Reference:
