Network Segmentation

Architect sections of the network to isolate critical systems, functions, or resources. Use physical and logical segmentation to prevent access to potentially sensitive systems and information. Use a DMZ to contain any internet-facing services that should not be exposed from the internal network. Configure separate virtual private cloud (VPC) instances to isolate critical cloud systems.

Techniques Addressed by Mitigation

Domain ID Name Use
Enterprise T1098 Account Manipulation

Configure access controls and firewalls to limit access to critical systems and domain controllers. Most cloud environments support separate virtual private cloud (VPC) instances that enable further segmentation of cloud systems.

T1098.001 Additional Cloud Credentials

Configure access controls and firewalls to limit access to critical systems and domain controllers. Most cloud environments support separate virtual private cloud (VPC) instances that enable further segmentation of cloud systems.

Enterprise T1557 Adversary-in-the-Middle

Network segmentation can be used to isolate infrastructure components that do not require broad network access. This may mitigate, or at least alleviate, the scope of AiTM activity.

T1557.001 LLMNR/NBT-NS Poisoning and SMB Relay

Network segmentation can be used to isolate infrastructure components that do not require broad network access. This may mitigate, or at least alleviate, the scope of AiTM activity.

Deny direct remote access to internal systems through the use of network proxies, gateways, and firewalls.

Enterprise T1136 Create Account

Configure access controls and firewalls to limit access to domain controllers and systems used to create and manage accounts.

T1136.002 Domain Account

Configure access controls and firewalls to limit access to domain controllers and systems used to create and manage accounts.

T1136.003 Cloud Account

Configure access controls and firewalls to limit access to critical systems and domain controllers. Most cloud environments support separate virtual private cloud (VPC) instances that enable further segmentation of cloud systems.

Enterprise T1565 Data Manipulation
