A.8.5 Secure Authentication would include:
-
Authentication Policies and Procedures: Documentation of formal authentication policies and procedures that define the organization's approach to secure authentication, including password complexity requirements, multi-factor authentication (MFA) usage, and account lockout policies.
-
User Account Management: Evidence of effective user account management practices, including user account creation, modification, and removal processes. This should include periodic review and removal of inactive or unnecessary accounts.
-
Password Management: Documentation of password management practices, such as password hashing and encryption, and controls in place to prevent password-related vulnerabilities, such as password reuse and storage in plain text.
-
Multi-Factor Authentication (MFA): Proof of implementation and usage of MFA or two-factor authentication (2FA) for accessing critical systems, applications, and sensitive data.
-
Access Control Mechanisms: Evidence of access control mechanisms implemented, such as role-based access control (RBAC), to ensure users have appropriate permissions based on their roles and responsibilities.
-
Strong Authentication Protocols: Documentation of the use of secure authentication protocols, such as OAuth, OpenID Connect, or SAML, to enable secure authentication and authorization across systems and applications.
-
Authentication Logs and Monitoring: Records of authentication logs and monitoring mechanisms used to track and detect suspicious or unauthorized access attempts.
-
User Training and Awareness: Evidence of user training and awareness programs that educate employees about secure authentication practices, password hygiene, and recognizing phishing attempts.
-
Incident Response Procedures: Documentation of incident response procedures specific to authentication-related incidents, outlining escalation paths and mitigation strategies.
-
Compliance with Standards and Regulations: Evidence of compliance with relevant security standards and regulations that address secure authentication requirements, such as ISO/IEC 27001 and industry-specific guidelines.
-
Third-Party Authentication Providers: Evidence of secure authentication practices when using third-party authentication providers or identity providers.
-
Regular Security Assessments: Documentation of periodic security assessments, including penetration testing and vulnerability assessments, to identify and address authentication-related vulnerabilities.
As an auditor, I would review these pieces of evidence to assess the organization's implementation of secure authentication practices. The goal is to ensure that the organization has robust authentication mechanisms in place to protect sensitive information, prevent unauthorized access, and minimize the risk of security breaches resulting from weak or compromised authentication methods.
