Usually when we admin a network, we need to know what are the protocols used more frequently, and why not, discover if someone are using improper P2P software; so we can use SPAN.
The Switched Port Analyzer (SPAN) feature, which is sometimes called port mirroring or port monitoring, selects network traffic for analysis by a network [...]

Two categories of protocol exist at the network layer: routed and routing.

On September 24, 2008, at about 16:00 GMT, the The Cisco Product Security Incident Response Team (PSIRT) has published 12 new vulnerability advisories. Mainly these vulnerabilities are DOS attack.

The configuration register can be used to change router behavior in several ways, such as:

how the router boots (into ROMmon, NetBoot)
options while booting (ignore configuration, disable boot messages)
console speed (baud rate for a terminal emulation session)

To view the current setting of the configuration register, use the show version command:

The Cisco On-Stage TelePresence Experience was an ambitious collaboration between Cisco and Musion Systems, which took place during [...]

Cisco Router HTTP Administration CSRF Remote Command Execution Universal Exploit. Replace “10.10.10.1″ with the IP address of the target router, embed this in a web page and hope for the best. This is only for test use.

Cisco routers with the HTTP administration interface enabled are vulnerable to an CSRF (Cross-Site Request Forgery) vulnerability that can yield remote command execution with level 15 privileges.
An attacker can execute ANY command on the router with level 15 (root, same as enable) privileges (usually level 15 user by default) by getting a target user (administrator [...]

In a network environment, it is a good practice monitor Cisco devices.
One of the most famous protocol to control and manage Cisco devices is SNMP (Simple Network Management Protocol).
SNMP exposes management data in the form of variables on the managed systems, which describe the system configuration. These variables can then be queried (and sometimes set) [...]
