SONAR (Symantec Online Network for Advanced Response)utilizesSymantec Insightto help reduce false positives in malware detection. Symantec Insight provides a reputation-based system that evaluates the trustworthiness of files based on data gathered from millions of endpoints worldwide.
* How Symantec Insight Reduces False Positives:
* Insight assigns reputation scores to files, which helps SONAR determine whether a file is likely benign or potentially malicious. Files with high reputation scores are less likely to be flagged as threats.
* This reputation-based analysis allows SONAR to avoid marking trusted files (e.g., common, widely-used applications) as malicious, thus reducing the rate of false positives.
* Advantages Over Other Options:
* While virus and spyware definitions (Option A) provide detection signatures, they are static and do not offer the real-time, behavior-based analysis that Insight provides.
* TheFile Fingerprint list(Option B) andExtended File Attributes (EFA) table(Option D) are not used by SONAR specifically for false-positive reduction.
References: Symantec Insight's integration with SONAR enhances threat detection accuracy by minimizing false positives based on file reputation and prevalence.

In aSymantec Endpoint Detection and Response (SEDR)database search, an event labeled withoperation:1 corresponds 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.

Lateral Movementis the type of security threat used by attackers toexploit vulnerable applicationsand move across systems within a network. This technique allows attackers to gain access to multiple systems by exploiting vulnerabilities in applications, thereby advancing deeper into the network.
* Understanding Lateral Movement:
* Lateral movement involves exploiting software vulnerabilities to access additional systems and data resources.
* Attackers use this method to spread their influence within a compromised network, often leveraging application vulnerabilities to pivot to other systems.
* Why Other Options Are Incorrect:
* Privilege Escalation(Option B) focuses on gaining higher access rights on a single system.
* Credential Access(Option C) involves stealing login credentials rather than exploiting applications.
* Command and Control(Option D) refers to the communication between compromised devices and an attacker's server, not the exploitation of applications.
References: Lateral movement leverages application vulnerabilities to expand attacker access within an organization's network, making it a common threat vector in targeted attacks.

ForWindows 10 in S mode, applications and agents like theSymantec Endpoint Security Complete (SESC) Network Integrity agentmust be obtained from trusted sources, specifically theMicrosoft Store. Windows
10 in S mode restricts installations to apps from the Microsoft Store to enhance security, thus requiring the SESC agent to be distributed through this channel.
* Why the Microsoft Store:
* Windows 10 in S mode is designed to only allow apps verified by Microsoft to ensure a controlled and secure environment.
* By providing the Network Integrity agent through the Microsoft Store, Symantec ensures that it complies with S mode's security restrictions.
* Why Other Options Are Not Suitable:
* SESC Installation files(Option A),MDM distribution(Option B), andICDm package(Option D) do not comply with Windows 10 S mode requirements.
References: The Microsoft Store is the designated distribution source for apps in Windows 10 S mode environments.
