How to secure your network infrastructure
Securing your network infrastructure is crucial to protect against cyber threats and maintain data integrity. Here are some essential steps to enhance security:
- Segment and Segregate Networks:
- Divide your network into segments based on function (e.g., production, development, guest). Isolate critical systems from less sensitive ones1.
- Limit lateral communications between segments to minimize attack surface.
- Harden Network Devices:
- Configure routers, switches, and firewalls with secure settings. Disable unnecessary services and change default credentials1.
- Regularly update firmware and apply security patches.
- Secure Access to Infrastructure Devices:
- Use strong authentication mechanisms (e.g., multi-factor authentication) for device access1.
- Restrict physical access to network equipment.
- Perform Out-of-Band (OoB) Network Management:
- Set up a separate management network for device administration. OoB management ensures secure access even during network disruptions1.
- Validate Hardware and Software Integrity:
- Regularly verify the integrity of network devices. Detect any unauthorized changes or tampering1.
Remember, network infrastructure security is an ongoing process. Stay vigilant, monitor logs, and adapt to emerging threats
