Symantec ProxySG providing intermediary services for FTP must inspect outbound FTP communications traffic for protocol compliance and protocol anomalies.

Description
Application protocol anomaly detection examines application layer protocols such as FTP to identify attacks based on observed deviations in the normal RFC behavior of a protocol or service. This type of monitoring allows for the detection of known and unknown exploits that exploit weaknesses of commonly used protocols. Since protocol anomaly analysis examines the application payload for patterns or anomalies, an FTP proxy must be included in the ALG. This ALG will be configured to inspect inbound and outbound FTP communications traffic to detect protocol anomalies such as malformed message and command insertion attacks.

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-104219r1_chk)

Determine whether FTP proxying is enabled to provide inspection. 1. Log on to the Web Management Console. 2. Browse to Configuration >> Services >> Proxy Services. 3. Click the "Standard", "Predefined Service Group" and verify that the FTP service is set to "Intercept". If Symantec ProxySG providing intermediary services for FTP does not inspect outbound FTP communications traffic for protocol compliance and protocol anomalies, this is a finding.

Fix Text (F-100381r1_fix)

Enable outbound FTP proxying to inspect this traffic for compliance and anomalies. 1. Log on to the Web Management Console. 2. Browse to Configuration >> Services >> Proxy Services. 3. Click the "Standard", "Predefined Service Group" and set FTP service to "Intercept". 4. Click "Apply".
