The Symantec Endpoint Protection client Auto-Protect Scan Actions for Security Risks must be configured to Quarantine Risk if first action fails.


Overview

Finding ID Version Rule ID IA Controls Severity
V-42663 DTASEP042 SV-55391r1_rule Medium
Description
Malware may have infected a file that is necessary to the user. By configuring the antivirus software to first attempt to delete the infected file, availability to the file is not sacrificed. If a deleting attempt is not successful, however, quarantining the file is the only safe option so as to ensure the malware is not introduced onto the system or network.
