1. Access Control Lists (ACLs): ACLs are used to provide access control to the router by defining if and what kind of packets can be allowed to or denied from passing through the router.
2. Firewall Solutions: Firewalls can be used to block potentially unwanted traffic from coming into and leaving the network.
3. Intrusion Detection System (IDS): This system can detect attempts to gain unauthorised access to the router or network.
4. Network Address Translation (NAT): NAT masks the internal IP addresses of computers on the network, making it harder for external threats to locate the computer.
5. Virtual Private Networks (VPN): VPNs are used to encrypt data between the router and other computers on the network.
6. Strong Passwords and Encryption: Strong passwords and encryption can be used to protect access to the router or other important components of the network.
