Overview

Finding ID Version Rule ID IA Controls Severity
V-1174 WN08-SO-000031 SV-48063r1_rule ECSC-1 Low
Description
Open sessions can increase the avenues of attack on a system. This setting is used to control when a computer disconnects an inactive SMB session. If client activity resumes, the session is automatically re-established. This protects critical and sensitive network data from exposure to unauthorized personnel with physical access to the computer.
