When configuring a Virus and Spyware Protection policy with the actions to 'Clean risk' first and 'Delete risk' if cleaning fails, two important considerations are:

False Positives (C): There is a risk that legitimate files may be falsely identified as threats and deleted if the cleaning action fails. This outcome underscores the importance of careful policy configuration to avoid loss of important files.

Quarantine Copy (E): Even if a file is deleted, a copy might still remain in the quarantine. This backup allows for retrieval if the deletion was a false positive or if further analysis of the file is required for investigation purposes.

These considerations help administrators avoid unintended data loss and maintain flexibility for future review of quarantined threats.

To prevent ransomware variants, such as Cryptolocker, from executing with double executable file names, an administrator should enable SONAR (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.

An Indicator of Compromise (IOC), such as irregularities in privileged user account activity, can signal that a privileged account may be compromised and used maliciously. This can involve deviations from typical login times, unusual commands or requests, or access to resources not typically utilized by the user. Monitoring such anomalies can help detect when an attacker has gained access to a privileged account and is attempting to establish control within the environment.

Active Directory (AD) is commonly targeted in attacks because it serves as a central directory for user identities, applications, and resources accessible across the network. This visibility makes it an attractive target for attackers to exploit for lateral movement, privilege escalation, and reconnaissance. Once compromised, AD provides attackers with significant insight into an organization's internal structure, enabling further exploitation and access to sensitive data.

Symantec Insight technology can prevent the download of unknown executables through a browser session by leveraging a cloud-based reputation service. Insight assesses the reputation of files based on data collected from millions of endpoints, blocking downloads that are unknown or have a low reputation. This technology is particularly effective against zero-day threats or unknown files that do not yet have established signatures.

In Integrated Cyber Defense Manager (ICDm), a tenant can encompass multiple domains, allowing organizations with complex structures to manage security across various groups or departments within a single tenant. Each tenant represents an overarching entity, while domains within a tenant enable separate administration and policy enforcement for different segments, providing flexibility in security management across large enterprises.

When creating a block list entry in Symantec Endpoint Detection and Response (SEDR), the SHA256 hash is a valid file attribute. SHA256 uniquely identifies files based on their content, making it a reliable attribute for ensuring that specific files, regardless of their names or creation dates, are accurately blocked. This hashing method helps prevent identified malicious files from executing, regardless of their locations or renaming attempts by attackers.

In Symantec Endpoint Security (SES), Device Groups enable administrators to apply policies based on specific endpoint profiles. Device Groups categorize endpoints according to characteristics like department, location, or device type, allowing tailored policy application that meets the specific security needs of each group. By using Device Groups, administrators can efficiently manage security policies, ensuring relevant protections are applied based on the endpoint's profile.
