Least Privilege Access:
- Apply the principle of least privilege by ensuring that users and devices only have access to the resources they need.
- Regularly review and adjust access controls based on changes in roles or requirements.
2. Implement Strong Identity and Access Management (IAM)
Multi-Factor Authentication (MFA):
- Enforce MFA across all access points, including internal and external resources.
- Use a combination of factors such as something the user knows (password), something they have (token), and something they are (biometrics).
Single Sign-On (SSO):
- Implement SSO to streamline authentication and improve security by reducing password fatigue.
- Ensure that SSO integrates with MFA for added security.
Continuous Authentication:
- Adopt continuous authentication methods that verify user identities based on behavior, location, and device health throughout the session.
- Use tools that can detect anomalies and automatically trigger re-authentication or limit access.
3. Secure Devices and Endpoints
Endpoint Security:
- Deploy endpoint security solutions that include antivirus, anti-malware, and advanced threat detection.
- Implement Endpoint Detection and Response (EDR) to monitor and respond to suspicious activities on endpoints.
Device Health Checks:
- Enforce device health checks before granting access to network resources, ensuring devices are up-to-date and free of known vulnerabilities.
- Use tools like Microsoft Defender or Google’s BeyondCorp to assess device compliance.
Mobile Device Management (MDM):
- Implement MDM to secure and manage mobile devices accessing the network.
- Enforce security policies such as encryption, remote wipe, and app restrictions on all mobile devices.
4. Monitor and Analyze Network Traffic
