To prevent ransomware variants, such as Cryptolocker, from executing withdouble executable file names, an administrator should enableSONAR (Symantec Online Network for Advanced Response). SONAR detects and blocks suspicious behaviors based on file characteristics and real-time monitoring,which is effective in identifying malicious patterns associated with ransomware. By analyzing unusual behaviors, such as double executable file names, SONAR provides proactive protection against ransomware threats before they can cause harm to the system.

ASLR (Address Space Layout Randomization)is a security technique used inMemory Exploit Mitigationthatrandomizes the memory address mapfor processes. By placing key data areas at random locations in memory, ASLR makes it more difficult for attackers to predict the locations of specific functions or buffers, thus preventing exploitation techniques that rely on fixed memory addresses.

How ASLR Enhances Security:

ASLR rearranges the location of executable code, heap, stack, and libraries each time a program is run, thwarting attacks that depend on known memory locations.

Why Other Options Are Incorrect:

ForceDEP(Option A) enforces Data Execution Prevention but does not randomize addresses.

SEHOP(Option B) mitigates exploits by protecting exception handling but does not involve address randomization.

ROPHEAP(Option D) refers to Return-Oriented Programming attacks rather than a mitigation technique.

References: ASLR is a widely used method in Memory Exploit Mitigation, adding randomness to memory locations to reduce vulnerability to exploitation​.

The Intrusion Prevention System (IPS) in Symantec Endpoint Protection operates by scanning inbound and outbound traffic packets against a defined list of signatures. This process aims to identify known attack patterns or anomalies that signify potential security threats.

When IPS detects a match in the traffic packet based on these custom signatures, the following sequence occurs:

Initial Detection and Match:The IPS engine actively monitors traffic in real-time, referencing its signature table. Each packet is checked sequentially until a match is found.

Halting Further Checks:Upon matching a signature with the inbound or outbound traffic, the IPS engine terminates further checks for other signatures in the same traffic packet. This design conserves system resources and optimizes performance by avoiding redundant processing once a threat has been identified.

Action on Detection:After identifying and confirming the threat based on the matched signature, the IPS engine enforces configured responses, such as blocking the packet, alerting administrators, or logging the event.

This approach ensures efficient threat detection by focusing only on the first detected signature, which prevents unnecessary processing overhead and ensures rapid incident response.

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.

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.
