How can routers defend the attack of ransomware?

Routers can defend against ransomware attacks and prevent network-wide infiltration through the following methods:

1. Implement strong firewall rules: Configure routers to block unauthorized traffic and restrict access to critical network resources. Utilize intrusion prevention systems (IPS) to identify and block suspicious activities.

2. Regularly update router firmware: Keep router firmware up to date to patch known vulnerabilities that could be exploited by ransomware attackers.

3. Enable access controls: Utilize access control lists (ACLs) to restrict access to network devices and resources based on predefined rules. Implement strong password policies and consider multifactor authentication for added security.

4. Segment the network: Divide the network into separate segments or VLANs to contain potential ransomware infections and prevent lateral movement across the network.

5. Implement network monitoring: Use network monitoring tools to detect unusual or malicious activity, such as sudden spikes in traffic or unauthorized access attempts, and respond promptly to mitigate threats.

6. Enable DNS filtering: Utilize DNS filtering services to block known malicious domains and prevent ransomware from communicating with command and control servers.

7. Backup data regularly: Implement regular data backups and store them offline or in a secure location to ensure data recovery in case of a ransomware attack.

By implementing these measures, routers can help defend against ransomware attacks and prevent network-wide infiltration.
