Description
Using older unauthorized versions or incorrectly configuring protocol negotiation makes the gateway vulnerable to known and unknown attacks that exploit vulnerabilities in this protocol. NIST SP 800-52 Rev2 provides guidance for client negotiation on either DOD-only or public-facing servers. Satisfies: SRG-NET-000062-VPN-000200, SRG-NET-000371-VPN-001650, SRG-NET-000530-VPN-002340, SRG-NET-000540-VPN-002350

Who does this work

8 NICE work roles and 7 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-258586r997505_chk)

Determine if the ICS uses TLS 1.2 to protect remote access transmissions. In the ICS Web UI, navigate to System >> Configuration >> Inbound SSL Options. 1. Under Allowed SSL and TLS Version, verify "Accept only TLS 1.2 (maximize security)" is checked. 2. Navigate to System >> Configuration >> Outbound SSL Options. 3. Under Allowed SSL and TLS Version, verify "Accept only TLS 1.2 (maximize security)" is checked. If the ICS does not use TLS 1.2, at a minimum, this is a finding.

Fix Text (F-62235r930445_fix)

Configure the ICS to uses TLS 1.2 to protect remote access transmissions. In the ICS Web UI, navigate to System >> Configuration >> Inbound SSL Options. 1. Under Allowed SSL and TLS Version, check the box for "Accept only TLS 1.2 (maximize security)". 2. Click "Save Changes". 3. Click "Proceed" for acceptance of Cipher Change. Navigate to System >> Configuration >> Outbound SSL Options. 1. Under Allowed SSL and TLS Version, check the box for "Accept only TLS 1.2 (maximize security)". 2. Click "Save Changes". 3. Click "Proceed" for acceptance of Cipher Change.
