When a devicefails a Host Integrity checkin Symantec Endpoint Protection (SEP), it isquarantined. This means that the device's access to network resources may be restricted to prevent potential security risks from spreading within the network. Quarantine helps contain devices that do not meet the configured security standards, protecting the overall network integrity.
* Purpose of Quarantine on Host Integrity Failure:
* Host Integrity checks ensure that endpoint devices comply with security policies, such as having up-to-date antivirus signatures or required patches.
* If a device fails this check, quarantine limits its network connectivity, enabling remediation actions without exposing the network to possible risks from the non-compliant device.
* Why Other Options Are Less Suitable:
* Antimalware scans(Option A) anddevice restarts(Option B) are not default responses to integrity check failures.
* Administrative notifications(Option D) may be logged but do not provide containment as quarantine does.
References: Quarantining non-compliant devices is a standard response to Host Integrity check failures, ensuring network protection while remediation occurs.

To view all devices impacted by asuspicious file, the administrator should go to theDiscovered Items list, select the specific file, and then view the impacted devices from theDetails page.
* Steps to View Impacted Devices:
* Navigate to theDiscovered Items listwithin the management console.
* Locate and select the suspicious file in question to open itsDetails page.
* On the Details page, a list of devices associated with the file is displayed, providing insights into which endpoints are potentially impacted by the suspicious activity.
* Why Other Options Are Less Suitable:
* Options A and B do not provide the specific device list for a selected file.
* Option D is incorrect as it implies selecting by device first rather than by suspicious file.
References: The Discovered Items list and file-specific Details page allow administrators to trace a file's footprint across multiple devices.

In the Discovery phase of a cyber attack, attackers attempt to map the network, identify vulnerabilities, and gather information.FirewallandIntrusion Prevention System (IPS)are the most effective security controls to mitigate threats associated with this phase:
* Firewall:The firewall restricts unauthorized network access, blocking suspicious or unexpected traffic that could be part of reconnaissance efforts.
* IPS:Intrusion Prevention Systems detect and prevent suspicious traffic patterns that might indicate scanning or probing activity, which are common in the Discovery phase.
Together, these controls limit attackers' ability to explore the network and identify potential vulnerabilities.

Amedium-priority incidentin Symantec's framework indicates that the incidentmay have an impact on the business. This priority level suggests that while the incident is not immediately critical, it still poses a potential risk to business operations and should be addressed.
* Understanding Medium-Priority Impact:
* Medium-priority incidents are not severe enough to cause immediate operational disruption but may still affect business processes or data security if left unresolved.
* Prompt action is recommended to prevent escalation or downstream effects on business functions.
* Why Other Options Are Incorrect:
* Business outage(Option B) would likely be classified as high priority.
* No impact on critical operations(Option C) would suggest a lower priority.
* Safe to ignore(Option D) does not reflect the importance of addressing medium-priority incidents.
References: A medium-priority incident signifies a non-critical yet potentially impactful event, requiring appropriate attention to mitigate business risks.

TheProcess Viewfeature in Symantec Endpoint Detection and Response (EDR) provides a detailed and comprehensive view of activities associated with an infected endpoint. It displays a graphical representation of processes, their hierarchies, and interactions, which helps security teams understand the behavior and spread of malware on the system.
* Advantages of Process View:
* Process View shows the relationship between different processes, including parent-child structures, which can reveal how malware propagates or persists on an endpoint.
* This visualization is instrumental in tracking the full impact of an infection, helping administrators identify malicious activities linked to specific processes.
* Why Other Options Are Less Suitable:
* Entity Viewis more focused on broader data relationships, not specific infected process activities.
* Full DumpandEndpoint Dumprefer to memory or system dumps, which are useful for in-depth forensic analysis but do not provide an immediate, clear picture of endpoint activity.
References: Process View is designed within EDR for tracking endpoint infection paths and behavioral analysis.
