Remediation, mitigation, notes, history and related intelligence
REMEDIATION
1. Application Log Monitoring
Detection: Monitor authentication logs for system and application login failures of valid accounts. If authentication failures are high, there may be a brute-force attempt to gain access to a system using legitimate credentials.
Remediation:
Implement Account Lockout Policies: Configure account lockout policies to temporarily disable accounts after several failed login attempts.
Strengthen Password Policies: Enforce strong password policies requiring complex and unique passwords.
Multi-Factor Authentication (MFA): Implement MFA to add an additional layer of security beyond just passwords.
Regular Audits: Conduct audits of authentication logs to identify and promptly respond to suspicious activities.
2. Command Execution Monitoring
Detection: Monitor executed commands and arguments that may use brute force techniques to access accounts when passwords are unknown or password hashes are obtained.
Remediation:
Limit Command Execution: Restrict the use of commands that are typically associated with brute force attempts, using role-based access control.
Security Patches: Ensure all systems are up to date with the latest security patches to prevent exploitation of known vulnerabilities.
Command Whitelisting: Implement command whitelisting to allow only authorized commands to be executed.
Incident Response Plan: Develop and maintain an incident response plan to quickly address and mitigate any detected brute force attempts.
3. User Account Authentication Monitoring
Detection: Monitor for many failed authentication attempts across various accounts that may result from password spraying attempts.
Remediation:
Account Lockout and Alerts: Set up account lockout mechanisms and alert systems to notify administrators of multiple failed login attempts.
User Education: Educate users on the importance of using unique passwords for different accounts and the risks associated with password reuse.
Implement Password Managers: Encourage password managers to help users create and manage complex passwords.
Network Segmentation: Segment the network to limit the access of compromised accounts and reduce the spread of attacks.
Review and Harden Authentication Mechanisms: Regularly review and strengthen authentication mechanisms using MFA and other advanced security measures.
