Limit Access to Resource Over Network
Prevent access to file shares, remote access to systems, unnecessary services. Mechanisms to limit access may include use of network concentrators, RDP gateways, etc.
Privileged Account Management
Manage the creation, modification, use, and permissions associated to privileged accounts, including SYSTEM and root.
Disable or Remove Feature or Program
Remove or deny access to unnecessary and potentially vulnerable software to prevent abuse by adversaries.
Multi-factor Authentication
Use two or more pieces of evidence to authenticate to a system; such as username and password in addition to a token from a physical smart card or token generator.
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...
User Account Management
Manage the creation, modification, use, and permissions associated to user accounts.
Audit
Perform audits or scans of systems, permissions, insecure software, insecure configurations, etc. to identify potential weaknesses.
Operating System Configuration
Make configuration changes related to the operating system or a common feature of the operating system that result in system hardening against techniques.
Behavior Prevention on Endpoint
Use capabilities to prevent suspicious behavior patterns from occurring on endpoint systems. This could include suspicious process, file, API call, etc. behavior.
Antivirus/Antimalware
Use signatures or heuristics to detect malicious software.
User Training
Train users to be aware of access or manipulation attempts by an adversary to reduce the risk of successful spearphishing, social engineering, and other techniques that involve user interaction.
Password Policies
Set and enforce secure password policies for accounts.
Application Developer Guidance
This mitigation describes any guidance or training given to developers of applications to avoid introducing security weaknesses that an adversary may be able to take advantage of.
Filter Network Traffic
Use network appliances to filter ingress or egress traffic and perform protocol-based filtering. Configure software on endpoints to filter network traffic.
Active Directory Configuration
Configure Active Directory to prevent use of certain techniques; use SID Filtering, etc.
Account Use Policies
Configure features related to account use like login attempt lockouts, specific login times, etc.
Credential Access Protection
Use capabilities to prevent successful credential access by adversaries; including blocking forms of credential dumping.
Privileged Process Integrity
Protect processes with high privileges that can be used to interact with critical system components through use of protected process light, anti-process injection defenses, or other process integrity enforcement measures.
Data Backup
Take and store data backups from end user systems and critical servers. Ensure backup and storage systems are hardened and kept separate from the corporate network to prevent compromise.
Restrict Web-Based Content
Restrict use of certain websites, block downloads/attachments, block Javascript, restrict browser extensions, etc.
Restrict Registry Permissions
Restrict the ability to modify certain hives or keys in the Windows Registry.
Restrict File and Directory Permissions
Restrict access by setting directory and file permissions that are not specific to users or privileged accounts.
Data Loss Prevention
Use a data loss prevention (DLP) strategy to categorize sensitive data, identify data formats indicative of personal identifiable information (PII), and restrict exfiltration of sensitive data.(Citation: PurpleSec Data Loss Prevention)
Application Isolation and Sandboxing
Restrict execution of code to a virtual environment on or in transit to an endpoint system.
Exploit Protection
Use capabilities to detect and block conditions that may lead to or be indicative of a software exploit occurring.
Vulnerability Scanning
Vulnerability scanning is used to find potentially exploitable software vulnerabilities to remediate them.
Update Software
Perform regular software updates to mitigate exploitation risk.
Software Configuration
Implement configuration changes to software (other than the operating system) to mitigate security risks associated to how the software operates.
Network Intrusion Prevention
Use intrusion detection signatures to block traffic at network boundaries.
Remote Data Storage
Use remote security log and sensitive file storage where access can be controlled better to prevent exposure of intrusion detection log data or sensitive information.
Limit Software Installation
Block users or groups from installing unapproved software.
Do Not Mitigate
This category is to associate techniques that mitigation might increase risk of compromise and therefore mitigation is not recommended.
