When threat hunting, it is important for anIncident Responderto search forsuspicious registry and system file changesbecause attackers can use these modifications toestablish persistencewithin an infected host. Persistence allows attackers to maintain control over the compromised system, even after reboots or security updates.

Persistence via Registry and System Files:

Attackers often modify registry keys or add malicious files in system directories to ensure their malware automatically starts with the system.

By establishing persistence, attackers can retain their foothold in the system, making it more difficult for security teams to fully eradicate the threat.

Why Other Options Are Incorrect:

While attackers may attempt totrick users(Option B),shadow sessions(Option C), or causeDNS anomalies(Option D), registry and system file changes are primarily associated with persistence techniques.

References: Checking for persistence mechanisms is a critical part of threat hunting, as these often involve registry and system file modifications​.

TheIntrusion Prevention System (IPS)provides asecond layer of defenseafter the Symantec firewall. While the firewall controls access and traffic flow at the network perimeter, IPS actively monitors and inspects incoming and outgoing traffic for signs of malicious activity, such as exploit attempts and suspicious network patterns.

How IPS Complements the Firewall:

The firewall acts as the first layer of defense, blocking unauthorized access based on rules and policies.

IPS then inspects allowed traffic in real-time, identifying and blocking attacks that may evade basic firewall rules, such as known exploits and abnormal network behaviors.

Why Other Options Are Less Effective:

Virus and Spyware(Option A) focuses on malware detection within files and programs, not network defense.

Host Integrity(Option B) is related to compliance, andSystem Lockdown(Option D) controls application execution but does not monitor network traffic.

References: Intrusion Prevention adds a critical layer of defense in Symantec’s network security stack, working in conjunction with the firewall for comprehensive protection​.

In aSymantec Endpoint Detection and Response (SEDR)database search, an event labeled withoperation:1corresponds to aFile Openaction. This identifier is part of SEDR’s internal operation codes used to log file interactions. When querying or analyzing events in the SEDR database, recognizing this code helps Incident Responders understand that the action recorded was an attempt to access or open a file on the endpoint, which may be relevant in tracking suspicious or malicious activities.

An administrator can add anew replication partnerduring theinitial installation of a new sitein Symantec Endpoint Protection Manager (SEPM). This timing is essential because:

Initial Setup of Replication:Configuring replication during installation ensures that the new site can immediately synchronize policies, logs, and other critical data with the existing SEPM environment.

Seamless Data Consistency:Setting up replication from the beginning avoids the need for complex data merging later and ensures both sites are aligned in real time.

Configuring replication at the installation stage facilitates a smoother integration and consistent data flow between SEPM sites.

To locate unmanaged endpoints within a specific network subnet, an administrator should utilize theDiscover and Deploysetting. This feature scans the network for endpoints without security management, enabling administrators to identify and initiate the deployment of Symantec Endpoint Protection agents on unmanaged devices. This proactive approach ensures comprehensive coverage across the network, allowing for efficient detection and management of all endpoints within the organization.

TheSystemalert rule category includesevents generated about the cloud console. These alerts relate to system-level activities within the management console, such as administrative actions, system health checks, and other essential notifications related to console operations.

Types of Alerts in System Category:

System alerts cover activities directly associated with the console and infrastructure, ensuring that administrators are informed of significant changes or issues affecting the management platform itself.

Why Other Options Are Incorrect:

Security(Option A) focuses on potential threats and security events.

Diagnostic(Option C) involves troubleshooting information but does not specifically cover console events.

Application Activity(Option D) pertains to application-specific events rather than console-level notifications.

References: System alerts provide visibility into cloud console-related events, crucial for managing and maintaining the console’s operational integrity​.

AnIndicator of Compromise (IOC), such asirregularities in privileged user account activity, can signal that a privileged account may be compromised and used maliciously. This can involve deviations from typical login times, unusual commands or requests, or access to resources not typically utilized by the user. Monitoring such anomalies can help detect when an attacker has gained access to a privileged account and is attempting to establish control within the environment.

In Symantec Endpoint Protection (SEP) Application Control policies, applications are managed through lists: an Allowed list (applications approved for use) and a Blocked list (applications restricted or prohibited). When a user encounters an application that is not explicitly on either the Allowed or Blocked list, it falls into a neutral category.

For accessing this application, the typical process includes:

Requesting an Override:The user can initiate a request to temporarily or permanently allow access to the application. This process usually involves contacting the administrator or following a specified override protocol to gain necessary permissions.

Administrator Review:Upon receiving the override request, the administrator evaluates the application to ensure it aligns with organizational security policies and compliance standards.

Override Approval:If deemed safe, the application may be added to the Allowed list, granting the user access.

This request mechanism ensures that unlisted appli

Symantec Endpoint Detection and Response (EDR) providesBlock Listing or Allow Listingof specific files as a rapid remediation action. This feature enables administrators to quickly contain or permit files across endpoints based on identified threat intelligence, thereby reducing the risk of further spread or false positives.

Use of Block Listing and Allow Listing:

Block Listing ensures that identified malicious files are immediately prevented from executing on other endpoints, providing containment for known threats.

Allow Listing, conversely, can be used for trusted files to prevent unnecessary interruptions if false positives occur.

Why Other Options Are Less Relevant:

Filtering for specific attributes(Option A) aids in identifying threats but is not a remediation action.

Detonating Memory Exploits(Option B) is a separate analysis action, not direct remediation.

Automatically stopping behaviors(Option C) pertains to behavior analysis rather than the specific action of listing files for rapid response.

References: The Block List and Allow List capabilities in Symantec EDR are key for efficient endpoint remediation and control over detected files​.
