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

In Symantec Endpoint Security (SES), when an administrator edits and saves an existing policy, the system creates a new version.All previous versions of the policy are added to the policy archive list. This allows administrators to retain a historical record of policy configurations, which can be referenced or reactivated if needed.

Purpose of Policy Versioning and Archiving:

The policy archive provides an organized history of policy changes, enabling administrators to track adjustments over time or roll back to a previous version if necessary.

Why Other Options Are Incorrect:

Dormant until reactivated(Option A) implies temporary inactivity but does not match the archival system in SES.

Deleted after 30 days(Option B) would result in loss of policy history.

Active and assignable(Option C) is incorrect as only the latest version is typically active for assignments.

References: The SES advanced policy versioning system archives previous versions for historical reference and policy management​.

In Symantec Endpoint Protection (SEP), when files are blocked by hash in the deny list policy,SHA256is supported in addition to MD5. SHA256 provides a more secure hashing algorithm compared to MD5 due to its longer hash length and higher resistance to collisions, making it effective for uniquely identifying and blocking malicious files based on their fingerprint.

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.

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.

For centralized control overcontent types and versions, the organization should use anInternal LiveUpdate Server. This content distribution method allows administrators to centrally manage which updates and definitions are available for endpoints, providing flexibility and control over update timing and content.

Benefits of an Internal LiveUpdate Server:

This server enables administrators to decide which content versions to distribute to endpoints, ensuring that all clients are updated consistently according to the organization’s policies.

It supports Windows environments efficiently, distributing required updates without relying on external sources.

Why Other Options Are Less Suitable:

Management Server(Option A) can provide content updates but does not offer the same centralized version control.

Group Update Provider(Option B) distributes content locally within groups but lacks centralized control over content versions.

External LiveUpdate Server(Option D) pulls updates directly from Symantec, limiting internal control over version and content type.

Push Notificationis the communication method used within Symantec Endpoint Security (SES) to facilitatereal-time management. This method enables:

Immediate Updates:SES can instantly push policy changes, updates, or commands to endpoints without waiting for a standard polling interval.

Efficient Response to Threats:Push notifications allow for faster reaction times to emerging threats, as instructions can be delivered to endpoints immediately.

Reduced Resource Usage:Unlike continuous polling, push notifications are triggered as needed, reducing network and system resource demands.

Push Notification is crucial for achieving real-time management in SES, providing timely responses and updates to enhance endpoint security.

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.

If an administrator has enabled the setting to manage policies from the cloud and needs to reverse this, they must follow these steps:

Unenroll the SEPM (Symantec Endpoint Protection Manager)from the cloud management (ICDm).

Disable the cloud policy management settingwithin the SEPM.

Re-enroll the SEPMback into the cloud if required.

This process ensures that policy control is reverted from cloud management to local management on the SEPM. By following these steps, administrators restore full local control over policies, disabling any cloud-based management settings previously in effect.

In antimalware solutions,Level 5intensity is defined as a setting where the software blocks files that are considered either most certainly malicious or potentially malicious. This level aims to balance security with usability by erring on the side of caution; however, it acknowledges that some level of bothfalsepositives(legitimate files mistakenly flagged as threats) andfalse negatives(malicious files mistakenly deemed safe) may still occur.

This level is typically used in environments where security tolerance is high but with an understanding that some legitimate files might occasionally be flagged. It provides robust protection without the extreme strictness of the highest levels, thus reducing, but not eliminating, the possibility of false alerts while maintaining an aggressive security posture.

Threat Defense for Active Directory(TDAD) provides protection primarily at theAttack Surface Reductionstage in the Attack Chain. TDAD focuses on minimizing the exposure of Active Directory by deploying deceptive measures, such as honeypots and decoy objects, which limit the opportunities forattackers to exploit AD vulnerabilities or gather useful information. By reducing the visible attack surface, TDAD makes it more difficult for attackers to successfully initiate or escalate attacks within the AD environment.

Function of Attack Surface Reduction:

Attack Surface Reduction involves implementing controls and deceptive elements that obscure or complicate access paths for potential attackers.

TDAD’s deception techniques and controls help divert and confuse attackers, preventing them from finding or exploiting AD-related assets.

Why Other Options Are Incorrect:

Attack Prevention(Option B) andDetection and Response(Option C) occur later in the chain, focusing on mitigating and reacting to detected threats.

Breach Prevention(Option D) encompasses a broader strategy and does not specifically address TDAD’s role in reducing AD exposure.

References: TDAD’s role in reducing the attack surface for Active Directory supports preemptive measures against potential threats in the early stages of the attack chain​.
