Restrict File and Directory Permissions
Restrict access by setting directory and file permissions that are not specific to users or privileged accounts.
Execution Prevention
Block execution of code on a system through application control, and/or script blocking.
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.
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.
Code Signing
Enforce binary and application integrity with digital signature verification to prevent untrusted code from executing.
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.
Network Intrusion Prevention
Use intrusion detection signatures to block traffic at network boundaries.
Restrict Web-Based Content
Restrict use of certain websites, block downloads/attachments, block Javascript, restrict browser extensions, etc.
Privileged Account Management
Manage the creation, modification, use, and permissions associated to privileged accounts, including SYSTEM and root.
Audit
Perform audits or scans of systems, permissions, insecure software, insecure configurations, etc. to identify potential weaknesses.
User Account Management
Manage the creation, modification, use, and permissions associated to user accounts.
Limit Software Installation
Block users or groups from installing unapproved software.
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.
Disable or Remove Feature or Program
Remove or deny access to unnecessary and potentially vulnerable software to prevent abuse by adversaries.
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.
Password Policies
Set and enforce secure password policies for accounts.
Active Directory Configuration
Configure Active Directory to prevent use of certain techniques; use SID Filtering, etc.
Encrypt Sensitive Information
Protect sensitive information with strong encryption.
Credential Access Protection
Use capabilities to prevent successful credential access by adversaries; including blocking forms of credential dumping.
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.
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)
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...
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.
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.
Account Use Policies
Configure features related to account use like login attempt lockouts, specific login times, etc.
