Pass the Symantec Endpoint Security 250-580 Questions and answers with CertsForce

To identify devices on a Mac, administrators can use theGatherSymantecInfotool when the device is connected. This tool collects system information and diagnostic data specific to Symantec Endpoint Protection, helping administrators accurately identify and troubleshoot devices. Using GatherSymantecInfo ensures comprehensive data gathering, which is crucial for managing and supporting endpoints in a Mac environment.

Host Integrityis a Symantec Endpoint Security (SES) feature that ensuresdevices are compliant with a company's security standards. It does this by verifying system configurations, checking for required software (like antivirus or firewall settings), and validating other compliance criteria specified by the organization.

Functionality of Host Integrity:

Host Integrity checks are designed to ensure that each endpoint meets the necessary security configurations before granting it network access.

If a device is non-compliant, Host Integrity can enforce remediation steps, such as updating software or alerting administrators, to bring the device into compliance.

Why Other Options Are Less Suitable:

Intensive Protection(Option B) andAdaptive Protection(Option D) focus on active threat detection but not compliance enforcement.

Trusted Updater(Option C) is for allowing specific software updates without triggering alerts, not for overall compliance checking.

References: Host Integrity is a key feature in SES that promotes adherence to security policies across devices, ensuring network-wide compliance​.

ReviewingRelated Incidents and Eventsis crucial for an Incident Responder when preparing anAfter Actions Reportbecause it ensures that the Incident is fully resolved and allows the responder toidentify the most effective remediation method. This process provides a comprehensive understanding of the incident’s impact and helps in implementing measures to prevent recurrence.

Benefits of Reviewing Related Incidents and Events:

By analyzing related incidents and events, the responder gains insights into the incident’s scope, underlying causes, and any connections to other incidents, which can inform a more targeted and effective remediation strategy.

This thorough review can also help uncover patterns or vulnerabilities that were exploited, guiding future preventative measures.

Why Other Options Are Less Comprehensive:

Options A and B focus on immediate resolution but do not cover the importance of identifying the best remediation methods.

Option C relates to closing the incident but does not address the broader need for detailed remediation strategies.

References: Reviewing related incidents is a best practice in incident response for comprehensive resolution and informed remediation in Symantec EDR environments​.

To improveaccess speed for client filesstored on a file server, the administrator shouldEnable Network Cachewithin the client’sVirus and Spyware Protection policy. This setting allows client machines to cache scanned files from the network, thus reducing redundant scans and increasing read speed from the server.

How Network Cache Enhances Read Speed:

When Network Cache is enabled, previously scanned files are cached, allowing subsequent access without re-scanning, which decreases latency and improves access speed.

Why Other Options Are Less Effective:

Adding the server to a trusted host group(Option B) does not directly impact file read speeds.

Creating a firewall allow rule(Option C) allows connectivity but does not affect the speed of file access.

Enabling download randomization(Option D) only staggers update downloads and does not relate to read speeds from a file server.

References: Enabling Network Cache optimizes file access by reducing scan-related delays for files stored on network servers​.

Symantec Insightis a technology that deliversreputation ratings for binary executables. This system leverages data from Symantec’s Global Intelligence Network, which aggregates information from millions of users worldwide. Here’s how it works:

File Reputation Database:Symantec Insight assigns a reputation score to each executable based on various factors, including prevalence, origin, and behavior.

Dynamic Decision Making:By consulting these ratings, SEP can dynamically determine if a file is safe or potentially harmful, allowing or blocking files accordingly.

Reduced False Positives:Insight helps reduce false positives, as it can distinguish between widely used legitimate files and rare, potentially risky files.

This reputation-based approach enhances protection by preemptively identifying suspicious files without relying on traditional signature-based detection alone.

To notify administrators when manual remediation is required on an endpoint, the administrator should set up aSingle Risk Event notificationin SEP, with the action specified as"Left Alone". This configuration allows SEP to alert administrators only when the system does not automatically handle a detected risk, indicating that further manual intervention is required.

Setting Up the Notification:

Navigate toNotificationsin the SEP management console.

SelectSingle Risk Eventas the notification type and specify"Left Alone"for the action taken.

Enable options to log the notification and send an email alert to system administrators.

Rationale:

This approach ensures that administrators are only alerted when SEP detects a threat but cannot automatically remediate it, signaling a need for manual review and action.

Other options (e.g., System event notification, New risk detected) are broader and may trigger alerts unnecessarily, rather than focusing on cases needing manual attention.

References: Setting up targeted notifications, such as Single Risk Event with “Left Alone” action, is a best practice in SEP for efficient incident management​.

Dark Cornersalarms are part of Threat Defense for Active Directory and are triggered when domain misconfigurations or hidden backdoors are detected within the directory environment. Here’s how this alarm functions:

Detection of Hidden Threats:Dark Corners identifies and alerts administrators to hidden vulnerabilities within the Active Directory, such as unauthorized access paths or misconfigurations that could be exploited.

Security Assurance:By identifying these issues, administrators can proactively address and rectify potential risks that are otherwise challenging to detect.

Improved Active Directory Security:The Dark Corners alarm helps ensure that backdoors and misconfigurations do not provide attackers with hidden access points, strengthening the overall security posture of Active Directory.

This feature allows for a deeper level of inspection within Active Directory, safeguarding against subtle yet critical security risks.

To ensure that clients checking in every 10 days receivexdelta content packagesinstead of full content packages,30 content revisionsmust be retained on the Symantec Endpoint Protection Manager (SEPM). Here’s why:

Incremental Updates:xdelta packages are incremental updates that only download changes since the last update, conserving bandwidth and speeding up client updates.

Content Revision Retention:SEPM needs to retain a sufficient number of content revisions to allow clients that check in intermittently (such as every 10 days) to download incremental rather than full content packages.

Default Retention Recommendation:Retaining 30 content revisions ensures that clients are covered for up to 10 days of updates, meeting the requirement for xdelta delivery.

This setup optimizes resource usage by reducing the load on network and client systems.

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​.

To ensure that users cannot inadvertently block acustom internal application, the Symantec Endpoint Protection (SEP) administrator should create anAllow Firewall rulefor the application and place itat the bottom of the firewall rules, above the blue line.

Explanation of Firewall Rule Placement:

Placing the allow rule above the blue line ensures it remains prioritized in SEP’s firewall policy, meaning that user-created rules cannot override it.

This setup guarantees that the internal application is allowed through the firewall without disruption, while users can still create other firewall rules without affecting this critical application.

Why Other Options Are Less Effective:

Placing the rule below the blue line (Option A) would allow user-created rules to override it.

Creating anAllow Allrule (Option C) could inadvertently allow other unnecessary traffic, which is a security risk.

Setting a rule based on network adapter type (Option D) does not guarantee that it will cover all instances of the custom application.

References: In SEP firewall configurations, placing critical allow rules above the blue line protects essential applications from being unintentionally blocked​.
