Techniques Addressed by Mitigation

Domain ID Name Use
Enterprise T1557 Adversary-in-the-Middle

Limit access to network infrastructure and resources that can be used to reshape traffic or otherwise produce AiTM conditions.

.002 ARP Cache Poisoning

Create static ARP entries for networked devices. Implementing static ARP entries may be infeasible for large networks.

Enterprise T1612 Build Image on Host

Limit communications with the container service to local Unix sockets or remote access via SSH. Require secure port access to communicate with the APIs over TLS by disabling unauthenticated access to the Docker API on port 2375. Instead, communicate with the Docker API over TLS on port 2376.[1]

Enterprise T1609 Container Administration Command

Limit communications with the container service to managed and secured channels, such as local Unix sockets or remote access via SSH. Require secure port access to communicate with the APIs over TLS by disabling unauthenticated access to the Docker API and Kubernetes API Server.[1][2] In Kubernetes clusters deployed in cloud environments, use native cloud platform features to restrict the IP ranges that are permitted to access to API server.[3] Where possible, consider enabling just-in-time (JIT) access to the Kubernetes API to place additional restrictions on access.[4]

Enterprise T1613 Container and Resource Discovery

Limit communications with the container service to managed and secured channels, such as local Unix sockets or remote access via SSH. Require secure port access to communicate with the APIs over TLS by disabling unauthenticated access to the Docker API and Kubernetes API Server.[1][2] In Kubernetes clusters deployed in cloud environments, use native cloud platform features to restrict the IP ranges that are permitted to access to API server.[3] Where possible, consider enabling just-in-time (JIT) access to the Kubernetes API to place additional restrictions on access.[4]

Enterprise T1610 Deploy Container

Limit communications with the container service to managed and secured channels, such as local Unix sockets or remote access via SSH. Require secure port access to communicate with the APIs over TLS by disabling unauthenticated access to the Docker API, Kubernetes API Server, and container orchestration web applications.[1][2] In Kubernetes clusters deployed in cloud environments, use native cloud platform features to restrict the IP ranges that are permitted to access to API server.[3] Where possible, consider enabling just-in-time (JIT) access to the Kubernetes API to place additional restrictions on access.[4]

Enterprise T1546 .008 Event Triggered Execution: Accessibility Features

If possible, use a Remote Desktop Gateway to manage connections and security configuration of RDP within a network.[5]

Enterprise T1133 External Remote Services

Limit access to remote services through centrally managed concentrators such as VPNs and other managed remote access systems.

Enterprise T1200 Hardware Additions

Establish network access control policies, such as using device certificates and the 802.1x standard. [6] Restrict use of DHCP to registered devices to prevent unregistered devices from communicating with trusted systems.

Enterprise T1542 Pre-OS Boot

Prevent access to file shares, remote access to systems, unnecessary services. Mechanisms to limit access may include use of network concentrators, RDP gateways, etc.

.005 TFTP Boot

Restrict use of protocols without encryption or authentication mechanisms. Limit access to administrative and management interfaces from untrusted network sources.

Enterprise T1563 .002 Remote Service Session Hijacking: RDP Hijacking

Use remote desktop gateways.

Enterprise T1021 Remote Services

Prevent access to file shares, remote access to systems, unnecessary services. Mechanisms to limit access may include use of network concentrators, RDP gateways, etc.

.001 Remote Desktop Protocol

Use remote desktop gateways.

.002 SMB/Windows Admin Shares

Consider disabling Windows administrative shares.

Enterprise T1552 Unsecured Credentials

Limit network access to sensitive services, such as the Instance Metadata API.

.005 Cloud Instance Metadata API

Limit access to the Instance Metadata API using a host-based firewall such as iptables.

.007 Container API

Limit communications with the container service to managed and secured channels, such as local Unix sockets or remote access via SSH. Require secure port access to communicate with the APIs over TLS by disabling unauthenticated access to the Docker API and Kubernetes API Server.[1][2] In Kubernetes clusters deployed in cloud environments, use native cloud platform features to restrict the IP ranges that are permitted to access to API server.[3] Where possible, consider enabling just-in-time (JIT) access to the Kubernetes API to place additional restrictions on access.[4]
