| Description | ||||
| The OTSDN switch must be capable of capturing frames that are not engineered to be in the network and send them to a Security Information and Event Manager (SIEM) or midpoint sensor for analysis. | ||||

Check Text (C-102367r1_chk)
Review the SEL-2740S to ensure that the "no match criteria" rule is set to capture the packet for analysis as a possible injection or intrusion.
If the SEL-2740S is not configured to with the "no match criteria" rules for the Security Information and Event Manager (SIEM), this is a finding.
Fix Text (F-98519r2_fix)
To configure to capture all packets without flow rule match criteria, do the following:
1. Log on to OTSDN Controller using Permission Level 3.
2. Click "Flow Entries" in Navigation Menu.
3. Click "Add Flow" button.
4. Enter a "no match" flow rule for given ports.
5. Click "Submit".
