The 10 Information Assurance Mitigation Strategies
The NSA Top 10 (2016) organizes cybersecurity mitigation strategies into 10 key areas that address the most common attack vectors and vulnerabilities. Each strategy provides specific guidance on defensive measures that prevent or mitigate common attack techniques.
1. Application Whitelisting
Application whitelisting prevents unauthorized software from executing on systems, blocking malware and other malicious code even when other security controls fail. Organizations must maintain approved application lists, configure systems to allow only approved applications to execute, and implement processes for managing application approvals. Application whitelisting provides strong protection against malware, unauthorized software, and other malicious code that may attempt to execute on systems.
Implementation requires organizations to identify approved applications, configure systems to enforce whitelisting policies, and establish processes for approving new applications. Organizations should implement whitelisting on critical systems first, then expand coverage progressively. Application whitelisting must be balanced with operational requirements, ensuring that legitimate business applications can execute while preventing unauthorized software. Regular review and updates of whitelists ensure that approved applications remain current and that unauthorized software is prevented from executing.
2. Patch Applications and Operating Systems
Timely patching of applications and operating systems addresses known vulnerabilities that adversaries exploit to compromise systems. Organizations must establish patch management processes that identify vulnerabilities, test patches, and deploy patches promptly. Patch management programs should prioritize critical vulnerabilities, maintain inventories of systems and applications, and implement processes for rapid patch deployment. Timely patching prevents adversaries from exploiting known vulnerabilities to gain unauthorized access.
Organizations should implement automated patch management where possible, conduct regular vulnerability assessments, and maintain patch deployment schedules that balance security needs with operational stability. Patch testing processes ensure that patches don't introduce operational issues, while rapid deployment processes ensure that critical vulnerabilities are addressed promptly. Patch management programs must address both operating system patches and application patches, ensuring comprehensive vulnerability coverage.
3. Minimize Administrative Privileges
Minimizing administrative privileges reduces the risk of privilege escalation attacks and limits the damage that can occur when accounts are compromised. Organizations must implement least privilege principles, granting users only the minimum privileges necessary to perform their job functions. Administrative accounts should be restricted, monitored, and used only when necessary. Regular access reviews ensure that privileges remain appropriate as roles change and employment relationships end.
Organizations should implement role-based access controls, separate administrative accounts from standard user accounts, and implement processes for requesting and approving elevated privileges. Administrative account usage should be monitored and logged, enabling detection of unauthorized administrative activities. Privilege minimization requires coordination between IT, security, and business units to ensure that users receive appropriate access while maintaining security.
4. Secure Configurations
Secure configurations ensure that systems are configured according to security best practices, reducing attack surface and preventing common misconfigurations that adversaries exploit. Organizations must establish secure configuration baselines, implement configuration management processes, and monitor systems for configuration drift. Secure configurations address default settings, unnecessary services, and security settings that protect systems from common attack techniques.
Organizations should use security configuration guides, implement configuration management tools, and conduct regular configuration audits that verify systems remain configured securely. Secure configuration baselines should be maintained and updated as threats evolve, ensuring that configurations address current security concerns. Configuration management processes should prevent unauthorized changes, detect configuration drift, and enable rapid recovery from configuration errors.
5. Network Segmentation
Network segmentation isolates systems and limits lateral movement by adversaries who gain initial access. Organizations must implement network segmentation that separates systems based on security requirements, isolates critical systems, and prevents unauthorized network access. Segmentation strategies should consider system criticality, data sensitivity, and security requirements when designing network architectures.
Organizations should implement firewalls, network access controls, and network monitoring that enforce segmentation policies and detect unauthorized network access. Segmentation should isolate critical systems, separate user networks from administrative networks, and prevent lateral movement between network segments. Network segmentation requires careful planning and design, with security considerations integrated throughout network architecture.
6. Continuous Monitoring
Continuous monitoring enables organizations to detect security events, identify anomalies, and respond to threats promptly. Organizations must implement security monitoring capabilities that collect security events, analyze events for threats, and alert security personnel to potential security incidents.

Organizations should implement security information and event management (SIEM) systems, intrusion detection systems, and log management capabilities that support continuous monitoring. Monitoring capabilities should detect common attack patterns, identify anomalies, and provide alerts that enable rapid response. Continuous monitoring requires ongoing attention and resources, with monitoring capabilities that evolve as threats change.
7. Incident Response Planning
Incident response planning enables organizations to respond effectively to security incidents, minimizing damage and supporting rapid recovery. Organizations must develop incident response plans that define procedures for detecting, containing, eradicating, and recovering from security incidents. Incident response plans should address common attack scenarios, define roles and responsibilities, and establish communication procedures.
Organizations should conduct regular incident response exercises that test procedures, identify gaps, and improve response capabilities. Incident response teams should be established, trained, and equipped to respond to security incidents effectively. Incident response planning requires coordination across organizational functions, with clear procedures that enable rapid response when incidents occur.
8. Data Protection
Data protection ensures that sensitive information remains confidential and available, protecting data from unauthorized access, disclosure, and loss. Organizations must implement data protection controls including encryption, access controls, and backup capabilities that protect sensitive information. Data protection should address data at rest, data in transit, and data in use, providing comprehensive protection throughout the data lifecycle.
Organizations should classify data based on sensitivity, implement encryption for sensitive data, and establish backup and recovery procedures that ensure data availability. Data protection controls should prevent unauthorized access, detect data breaches, and enable rapid recovery from data loss. Data protection requires coordination between IT, security, and business units to ensure that sensitive information receives appropriate protection.
9. Access Controls
Access controls ensure that only authorized users can access systems and data, preventing unauthorized access and protecting sensitive information. Organizations must implement strong authentication mechanisms, enforce access policies, and monitor access activities. Access controls should address both human users and system accounts, with particular attention to privileged accounts that possess elevated permissions.
Organizations should implement multi-factor authentication for high-risk access, conduct regular access reviews, and enforce access policies consistently. Access control implementations should prevent unauthorized access, detect access anomalies, and enable rapid access revocation when necessary. Access controls require ongoing management, with processes for provisioning, reviewing, and revoking access as organizational needs change.
10. Security Awareness and Training
