Symantec 250-580 Exam With Confidence Using Practice Dumps

Calculating storage requirements for Symantec Endpoint Security (SES) involves gathering specific information related to data retention and event storage needs. The required information includes:

Number of Endpoints:Determines the scale of data to be managed.

EAR Data per Endpoint per Day:Refers to the Endpoint Activity Recorder (EAR) data generated by each endpoint daily, affecting storage usage.

Number of Days to Retain:Indicates the data retention period, which impacts the total volume of stored data.

Number of Endpoint Dumps and Dump Size:These parameters define the size and number of memory dumps, which are essential for forensic analysis and troubleshooting.

This information allows accurate calculation of storage needs, ensuring adequate capacity for logs, dumps, and activity data.

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​.

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​.
