computer network hardening

Question

what policies should be implemented for computer network hardening?

Answer 1

A few steps to harden computer networks involves

1. Configuring firewalls correctly and pruning rules (preferably every quarter),
2. Regularly monitoring CVE's and updating security patches for switches and other network devices,
3. Managing IAM user permissions (setting permissions on auto-expire and auto-review works best),
4. Monitoring network traffic for suspicious activities,
5. Monitoring, scanning and closing unused ports and encrypting data flows,
6. If possible, setting up Zero Trust within the whole network inward and outward with practical and sustainable rules, which - while laborious and difficult to implement, can be the touchstone for ultimate network hardening.

Answer 2

Many things can be done, but few major ones are

1. Proper firewall usage and settings
2. Disabling unnecessary, services, port, protocols
3. Patching your server
4. Implementing UTM security devices
