Password Policies: Set and enforce secure password policies for accounts to reduce the likelihood of unauthorized access. Strong password policies include enforcing password complexity, requiring regular password changes, and preventing password reuse. This mitigation can be implemented through the following measures:
Windows Systems:
- Use Group Policy Management Console (GPMC) to configure:
- Minimum password length (e.g., 12+ characters).
- Password complexity requirements.
- Password history (e.g., disallow last 24 passwords).
- Account lockout duration and thresholds.
Linux Systems:
- Configure Pluggable Authentication Modules (PAM):
- Use
pam_pwquality to enforce complexity and length requirements.
- Implement
pam_tally2 or pam_faillock for account lockouts.
- Use
pwunconv to disable password reuse.
Password Managers:
- Enforce usage of enterprise password managers (e.g., Bitwarden, 1Password, LastPass) to generate and store strong passwords.
Password Blacklisting:
- Use tools like Have I Been Pwned password checks or NIST-based blacklist solutions to prevent users from setting compromised passwords.
Regular Auditing:
- Periodically audit password policies and account configurations to ensure compliance using tools like LAPS (Local Admin Password Solution) and vulnerability scanners.
Tools for Implementation
Windows:
- Group Policy Management Console (GPMC): Enforce password policies.
- Microsoft Local Administrator Password Solution (LAPS): Enforce random, unique admin passwords.
Linux/macOS:
- PAM Modules (pam_pwquality, pam_tally2, pam_faillock): Enforce password rules.
- Lynis: Audit password policies and system configurations.
Cross-Platform:
- Password Managers (Bitwarden, 1Password, KeePass): Manage and enforce strong passwords.
- Have I Been Pwned API: Prevent the use of breached passwords.
- NIST SP 800-63B compliant tools: Enforce password guidelines and blacklisting.
Privileged Account Management: Privileged Account Management focuses on implementing policies, controls, and tools to securely manage privileged accounts (e.g., SYSTEM, root, or administrative accounts). This includes restricting access, limiting the scope of permissions, monitoring privileged account usage, and ensuring accountability through logging and auditing.This mitigation can be implemented through the following measures:
Account Permissions and Roles:
- Implement RBAC and least privilege principles to allocate permissions securely.
- Use tools like Active Directory Group Policies to enforce access restrictions.
Credential Security:
- Deploy password vaulting tools like CyberArk, HashiCorp Vault, or KeePass for secure storage and rotation of credentials.
- Enforce password policies for complexity, uniqueness, and expiration using tools like Microsoft Group Policy Objects (GPO).
Multi-Factor Authentication (MFA):
- Enforce MFA for all privileged accounts using Duo Security, Okta, or Microsoft Azure AD MFA.
Privileged Access Management (PAM):
- Use PAM solutions like CyberArk, BeyondTrust, or Thycotic to manage, monitor, and audit privileged access.
Auditing and Monitoring:
- Integrate activity monitoring into your SIEM (e.g., Splunk or QRadar) to detect and alert on anomalous privileged account usage.
Just-In-Time Access:
- Deploy JIT solutions like Azure Privileged Identity Management (PIM) or configure ephemeral roles in AWS and GCP to grant time-limited elevated permissions.
Tools for Implementation
Privileged Access Management (PAM):
- CyberArk, BeyondTrust, Thycotic, HashiCorp Vault.
Credential Management:
- Microsoft LAPS (Local Admin Password Solution), Password Safe, HashiCorp Vault, KeePass.
Multi-Factor Authentication:
- Duo Security, Okta, Microsoft Azure MFA, Google Authenticator.
Linux Privilege Management:
- sudo configuration, SELinux, AppArmor.
Just-In-Time Access:
- Azure Privileged Identity Management (PIM), AWS IAM Roles with session constraints, GCP Identity-Aware Proxy.
User Training: User Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques. Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures:
Create Comprehensive Training Programs:
- Design training modules tailored to the organization's risk profile, covering topics such as phishing, password management, and incident reporting.
- Provide role-specific training for high-risk employees, such as helpdesk staff or executives.
Use Simulated Exercises:
- Conduct phishing simulations to measure user susceptibility and provide targeted follow-up training.
- Run social engineering drills to evaluate employee responses and reinforce protocols.
Leverage Gamification and Engagement:
- Introduce interactive learning methods such as quizzes, gamified challenges, and rewards for successful detection and reporting of threats.
Incorporate Security Policies into Onboarding:
- Include cybersecurity training as part of the onboarding process for new employees.
- Provide easy-to-understand materials outlining acceptable use policies and reporting procedures.
Regular Refresher Courses:
- Update training materials to include emerging threats and techniques used by adversaries.
- Ensure all employees complete periodic refresher courses to stay informed.
Emphasize Real-World Scenarios:
- Use case studies of recent attacks to demonstrate the consequences of successful phishing or social engineering.
- Discuss how specific employee actions can prevent or mitigate such attacks.
