Password Management Policy

1. Introduction

1.1 Purpose and Scope: This policy outlines the requirements and procedures for managing passwords across all organizational information systems, applications, and accounts. It aims to protect sensitive information by preventing unauthorized access and maintaining the confidentiality, integrity, and availability of organizational assets. This policy applies to all employees, contractors, and third-party users accessing organizational systems.

1.2 Relevance to ISO 27001/2022: This policy directly addresses several controls within the ISO 27001/2022 standard, including but not limited to:

  • 5.1 Information security: Establishes a framework for secure password management practices.

  • 5.2 Information security risks: Addresses the risks associated with weak or compromised passwords.

  • 5.3 Information security objectives: Defines objectives for password security and control.

  • 5.4 Information security policies: Provides a documented policy for password management.

  • A.12.1.1 Access control: Implements robust access control measures through strong password requirements.

  • A.12.1.2 Password management: Directly addresses this control objective.

  • A.12.1.3 Account management: Includes procedures for account lockouts and password resets.

2. Key Components

This Password Management Policy includes the following key components:

  • Password Complexity Requirements: Specifies minimum length, character types, and frequency of changes.

  • Password Storage: Defines how passwords are stored and protected.

  • Password Lifecycle Management: Outlines procedures for password creation, change, and expiration.

  • Password Reset Procedures: Describes processes for recovering lost or forgotten passwords.

  • Account Lockout Policy: Defines the policy for account suspension after multiple failed login attempts.

  • Privileged Account Management: Specifies enhanced security controls for accounts with elevated privileges.

  • Third-Party Access: Addresses password management for external users and vendors.

  • Training and Awareness: Details employee training on secure password practices.

  • Monitoring and Auditing: Describes mechanisms for monitoring password usage and identifying security breaches.

3. Detailed Content

3.1 Password Complexity Requirements:

  • In-depth explanation: Passwords must meet minimum complexity criteria to withstand brute-force and dictionary attacks.

  • Best practices: Passwords must be at least 12 characters long, include uppercase and lowercase letters, numbers, and special characters (!@#$%^&*). Avoid using easily guessable information like names, dates, or common words. Prohibit the reuse of previous passwords.

  • Example: "P@$$wOrd123!"

  • Common pitfalls: Using weak passwords, reusing passwords across multiple accounts, using easily guessable information.

3.2 Password Storage:

  • In-depth explanation: Passwords should never be stored in plain text. Hashing algorithms should be used to securely store passwords. Salting and peppering should also be implemented to enhance security.

  • Best practices: Use a strong, one-way hashing algorithm (e.g., bcrypt, Argon2) with appropriate salt and pepper values.

  • Example: Using bcrypt to hash passwords before storing them in the database.

  • Common pitfalls: Storing passwords in plain text, using weak hashing algorithms, failing to use salt and pepper.

3.3 Password Lifecycle Management:

  • In-depth explanation: This covers the entire lifespan of a password, from creation to expiration and deletion.

  • Best practices: Passwords should expire regularly (e.g., every 90 days). Users should be prompted to change their passwords upon expiration.

  • Example: All passwords must be changed every 90 days. System will automatically lock user accounts after 3 failed login attempts. Users will be notified via email 7 days before their password expires.

  • Common pitfalls: Infrequent password changes, lack of automated password expiration.

3.4 Password Reset Procedures:

  • In-depth explanation: A clear and secure method for resetting forgotten passwords.

  • Best practices: Implement a multi-factor authentication (MFA) process for password resets. Avoid using easily guessable security questions.

  • Example: Users can initiate a password reset through a self-service portal. The system will send a verification code to their registered email address or mobile phone for MFA.

  • Common pitfalls: Lack of MFA, easily guessable security questions, insecure reset process.

3.5 Account Lockout Policy:

  • In-depth explanation: To prevent brute-force attacks, accounts should be temporarily locked after multiple failed login attempts.

  • Best practices: Implement an account lockout policy with a configurable threshold (e.g., 3 failed attempts within 15 minutes).

  • Example: After 3 failed login attempts, the account is locked for 30 minutes. After 5 failed attempts, the account is locked for 24 hours and requires IT intervention to unlock.

  • Common pitfalls: Lack of account lockout, weak lockout thresholds.

3.6 Privileged Account Management:

  • In-depth explanation: Enhanced security measures for accounts with administrative or elevated privileges.

  • Best practices: Use separate, dedicated privileged accounts. Implement strong authentication methods (e.g., MFA, smart cards). Regularly audit privileged account activity.

  • Example: Privileged accounts require MFA and are subject to stricter password change frequency (e.g., every 30 days). Access to privileged accounts is logged and monitored.

  • Common pitfalls: Insufficient monitoring, weak authentication methods, lack of segregation of duties.

3.7 Third-Party Access:

  • In-depth explanation: Managing passwords for external vendors and contractors accessing organizational systems.

  • Best practices: Use secure access methods (e.g., VPN, MFA). Regularly review and update third-party access.

  • Example: All third-party users must utilize a VPN and MFA to access organizational systems.

  • Common pitfalls: Lack of MFA, inadequate access control, infrequent review of access rights.

3.8 Training and Awareness:

  • In-depth explanation: Educate employees on secure password practices.

  • Best practices: Regular training sessions, phishing simulations, and awareness campaigns.

  • Example: Annual security awareness training covering password best practices and phishing prevention.

  • Common pitfalls: Lack of training, inadequate awareness campaigns.

3.9 Monitoring and Auditing:

  • In-depth explanation: Regularly monitoring and auditing password management practices to identify and address vulnerabilities.

  • Best practices: Use security information and event management (SIEM) tools to monitor login attempts, password changes, and account lockouts.

  • Example: Regularly review security logs for suspicious activities, such as multiple failed login attempts from unusual locations.

  • Common pitfalls: Lack of monitoring, infrequent auditing.

4. Implementation Guidelines

1. Develop and disseminate the policy: Ensure all employees receive and acknowledge the policy.

2. Implement password complexity rules: Configure systems to enforce password complexity requirements.

3. Establish password reset procedures: Implement a secure and user-friendly password reset mechanism.

4. Configure account lockout policy: Set appropriate thresholds for account lockouts.

5. Implement privileged account management: Implement enhanced security controls for privileged accounts.

6. Establish procedures for third-party access: Define and implement procedures for managing third-party access.

7. Conduct security awareness training: Provide regular training on secure password practices.

8. Monitor and audit password management: Implement systems for monitoring and auditing password management activities.
