Data from Configuration Repository: Network Device Configuration Dump

ID Name
T1602.001 SNMP (MIB Dump)
T1602.002 Network Device Configuration Dump

Adversaries may access network configuration files to collect sensitive data about the device and the network. The network configuration is a file containing parameters that determine the operation of the device. The device typically stores an in-memory copy of the configuration while operating, and a separate configuration on non-volatile storage to load after device reset. Adversaries can inspect the configuration files to reveal information about the target network and its layout, the network device and its software, or identifying legitimate accounts and credentials for later use.

Adversaries can use common management tools and protocols, such as Simple Network Management Protocol (SNMP) and Smart Install (SMI), to access network configuration files. [1] [2] These tools may be used to query specific data from a configuration repository or configure the device to export the configuration for later analysis.

ID Mitigation Description
M1041 Encrypt Sensitive Information

Configure SNMPv3 to use the highest level of security (authPriv) available. [3]

M1037 Filter Network Traffic

Apply extended ACLs to block unauthorized protocols outside the trusted network. [3]

M1031 Network Intrusion Prevention

onfigure intrusion prevention devices to detect SNMP queries and commands from unauthorized sources. Create signatures to detect Smart Install (SMI) usage from sources other than trusted director. [1]

M1030 Network Segmentation

Segregate SNMP traffic on a separate management network [3]

M1054 Software Configuration

Allowlist MIB objects and implement SNMP views. Disable Smart Install (SMI) if not used. [4] [1]

M1051 Update Software

Keep system images and software updated and migrate to SNMPv3. [2]


ID Data Source Data Component
DS0029 Network Traffic Network Connection Creation
Network Traffic Content

Identify network traffic sent or received by untrusted hosts or networks. Configure signatures to identify strings that may be found in a network device configuration. [5]
