Protecting networks from remote code execution (RCE) attacks is now more important than ever, as thousands of end-of-life Cisco routers are exposed to these vulnerabilities. On June 10, 2020 research revealed that over 19,000 Cisco devices were still unpatched and vulnerable to RCE attacks. In this article we'll explore the security risk posed by RCE attacks on vulnerable Cisco routers, how to protect your network from these types of attacks, and what security measures to take to ensure your network's safety.
Cisco routers are an important component of any network infrastructure, used to route data traffic and facilitate communications. However, if these devices are not properly protected, cybercriminals can exploit RCE vulnerabilities to access, modify, or steal sensitive data. In order to protect your network, it is important to properly configure, patch and monitor your routers to ensure they are always secure.
Ensure you are running the latest version of the operating system on your Cisco routers. Check for any available updates, and apply any available security patches and updates where appropriate. Additionally, it is important to review and adjust your router's security settings and configurations regularly. Properly configure the router to protect against known RCE attack vectors, and consider creating and applying a security profile for the router. Additionally, be aware of any default user accounts and passwords and remember to change them when necessary.
Another important security measure to take is to use secure network protocols, particularly when transferring sensitive data. Network protocols such as Secure Socket Layer (SSL) and Transport Layer Security (TLS) provide added security by encrypting data transmissions. Additionally, network traffic analysis and monitoring can help detect RCE attacks and other suspicious activity. This activity can be monitored using security products and protocols such as Snort, Bro IDS, and Intrusion Detection Systems (IDS).
By following these security best practices and taking these measures, you can protect your Cisco routers from RCE attacks. As end of life Cisco routers are vulnerable, it is important to update your network often and be aware of any potential threats and security patches. Additionally, be sure to monitor your network and traffic regularly, and practice good network configuring and patching techniques to ensure your network is secure from RCE attacks.
