The Cisco router NAC solves the problem. The so-called NAC is an architecture that allows multiple hardware and software components to work together to protect the user's network from adverse client attacks. 1. It is not easy to fully implement NAC, because the entire architecture contains too many different components from other vendors. For example, the architecture contains the NAC Policy Manager and mul

The following describes how to connect to a Cisco 2500 series router. In this section, assume that the router to be connected has received a basic configuration.Figure 1-6 shows the connection work that needs to be done after 2 5 0 1.

not encrypted during network transmission, strict control is required. For example, set a strong password, control the number of concurrent connections, strictly control the access address using the access list, and set user access control using AAA.8. We recommend that you use FTP instead of TFTP for iOS upgrade and backup and configuration file backup. For example:Router (config) # ip ftp Username blushinRouter (config) # ip ftp password 4tppa55w0rdRouter # copy startup-config ftp:9. Upgrade

A Cisco router is detected infected with a secret backdoor. Security company FireEye researchers reported that backdoor programs called SYNful knock were found on 14 Cisco routers in 4 countries. Cisco has confirmed this. The attack does not take advantage of the vulnerability of the product itself, but requires valid

. RPF reverse transmission path forwarding) is an input function activated on a network interface or sub-interface to process packets received by the router. It is very important to enable the CEF function on the vro, because RPF must rely on CEF. Unicast RPF is included in Cisco IOS 12.0 and later versions that support CEF, but does not support Cisco IOS 11.2 or
