ISO/IEC 27000 standards for information technology is a series of security techniques that can improve the overall information security of an organization. The standard defines requirements for your information security management system (ISMS). In short, if your organization is compliant with ISO 27000, your personal data and business sensitive data are in safe hands.

Here are a few information security controls that you can implement with WSO2 Identity Server to protect personal data and for overall information security risk management.

Multi-Factor Authentication of WSO2 Identity Server Enables Compliance with ISO 27000 - 9. Access Control

Relying only on one authentication factor puts your information security at risk with a single point of failure. If your knowledge, device, or biometric pattern is compromised, anyone who has it can impersonate the user, leading to a significant data breach. By using two-factor authentication, you create an additional layer of protection against anyone seeking unauthorized access, because although one factor is compromised, your information assets will be protected unless the second factor is exposed.

Security controls of ISO 27000

Rationale

9.1.1 Access Policy Control

9.4 System and application access control

9.4.1 Information access restrictions

9.4.2 Secure log-on procedures

● The need for two-factor authentication will vary with the business requirement. Based on the requirement, Role-Based Access Control and Attribute-Based Access Control can be achieved with WSO2 CIAM, Multi-Factor Authentication, and Adaptive Authentication.

● Adaptive Authentication will provide dynamic control over the authentication flow to provide more security in a user-friendly manner.

● The solution’s Adaptive Authentication can connect with an Open Policy Agent (OPA) or Analytics Server and control access based on the decisions given.

Identity Provisioning and Deprovisioning of WSO2 Identity Server Enables Compliance with ISO 27000 - 9. Access Control

Users can be provisioned or registered to WSO2 Identity Server in three ways.

  • Users can self-register
  • The administrator can invite users to register
  • Users can be provisioned just-in time during federation

The provisioning and de-provisioning in WSO2 Identity Server can be controlled by enforcing policies or changing permission levels required to achieve each task.

To enforce policies during provisioning and deprovisioning in WSO2 Identity Server:

  • WSO2 Identity Server ships with an inbuilt XACML engine to enforce XACML policies to achieve Rule Based Access Control or Role-Based Access Control during provisioning/registration or deprovisioning
  • Provisioning patterns can be configured in WSO2 Identity Server to outbound provision users in third-party systems
  • WSO2 Identity Server ships with an inbuilt workflow engine to activate a workflow during provisioning and deprovisioning. This will control the provisioning and deprovisioning by an approval process (multi-step or uni-step approvals)

Security controls of ISO 27000

Rationale

9.2 Responsibilities for assets

9.2.1 User registration and de-registration

9.2.2 User access provisioning

● Controlling provisioning identities depends on the business requirement. WSO2 Identity Server enables organizations to customize the existing features to achieve this requirement via extension points.

● Provisioning and deprovisioning of users, groups can be controlled through XACML policies and workflows

Password/Tokens/Secret Management of WSO2 Identity Server Enables Compliance with ISO 27000 - 9. Access Control

 Password Management

There are several ways to change the password using WSO2 Identity Server

  • Reset password or forgot password
  • Reset password through challenge questions
  • Administrator forcefully resets user's password in a critical situation
  • The user has to reset the password periodically and cannot reuse the same password
  • The password policy authenticator prompts the user periodically to reset the password and does not allow reusing of passwords

To secure user's password:

To secure WSO2 Identity Server passwords in files:

The plaintext passwords in configuration files can be encrypted using the secure vault implementation built into WSO2 Identity Server. Outside parties will not see the plaintext password. The keystore password and private key password of the product's primary keystore will serve as the root passwords for the secure vault. This is because the keystore passwords are needed to initialize the values encrypted by the secret manager in the secret repository. Therefore, the secret callback handler is used to resolve these passwords.

Security controls of ISO 27000

Rationale

9.4.3 Password management system

● Passwords can be encrypted or hashed with a salt as per requirement

● Passwords can be changed regularly with complex policies

Tokens and Secret Management

Best practices:

Key Management Features of WSO2 Identity Server Enables Compliance with ISO 27000 - 10.1 Cryptographic Control

Best Practices:

Two keystore can be maintained:

  • Internal keystore - used for encrypting/decrypting internal data. By default, the primary keystore is used as the internal keystore. The key rotation of the internal keystore can have a longer period compared to TLS keystores.
  • TLS Keystore - used for TLS communication. By default, the primary keystore is used as the TLS keystore. Key rotation of TLS key stores can be done frequently as these keys are exposed to outside systems more frequently.

Security controls of ISO 27000

Rationale

10.1 Cryptographic Controls

10.1.1 Policy on the user of Cryptographic controls

10.1.2 Key Management

● Tokens and secrets can be symmetrically encrypted(faster than Asymmetric encryption and industry-standard) with the internal keystore

● Separate keystores can be used for internal and TLS communications with frequent key rotations

Auditing and Logging Capabilities of WSO2 Identity Server Enables Compliance with ISO 27000 - 12.4 Logging and Monitoring

The Following logs can be monitored through WSO2 Identity Server:

  • Audit logs
  • Access Logs
  • DEBUG/WARN/ERROR Logs

WSO2 Identity Server supports logging capabilities for tracking down latencies due to database calls. See Working with Product Observability for instructions on how to configure and use this capability.

Digital evidence such as events and logs can be published to any popular SIEM for further analysis. E.g., SPLUNK integration

WSO2 Identity Server ships with its own Analytics Server to view login and session analytics in a dashboard. Dashboard details can be downloaded in a PDF format.

Best Practices:
