Adversaries may target the Management Information Base (MIB) to collect and/or mine valuable information in a network managed using Simple Network Management Protocol (SNMP). The MIB is a configuration repository that stores variable information accessible via SNMP in the form of object identifiers (OID).
If this is happening now
Checklists and playbooks to open while the alert is still live.
Playbook for this stage
Suspected data theft by an insider
A resignation with unusual file access, a DLP alert, or an unexplained large transfer.
how MITRE says to see it
Detection Strategy for SNMP (MIB Dump) on Network Devices
- Defenders may observe suspicious SNMP MIB enumeration through abnormal queries for large sets of OIDs, repeated SNMP GETBULK/GETNEXT requests, or queries originating from non-administrative IP addresses.
what reduces it
- M1031 Network Intrusion Prevention. Configure intrusion prevention devices to detect SNMP queries and commands from unauthorized sources.
- M1037 Filter Network Traffic. Apply extended ACLs to block unauthorized protocols outside the trusted network.
- M1030 Network Segmentation. Segregate SNMP traffic on a separate management network.
- M1054 Software Configuration. Allowlist MIB objects and implement SNMP views.
- M1051 Update Software. Keep system images and software updated and migrate to SNMPv3.
- M1041 Encrypt Sensitive Information. Configure SNMPv3 to use the highest level of security (authPriv) available.
