Infra Router and Switch Security Overview Router and Switch Security Overview "You are only as secure as your weakest link." Network security professionals often encounter this adage. While an attack on a web server can just render it unoperational, an attack on the edge router can cut off the entire network from its users. Throughout this chapter, the term router refers to Cisco IOS-based devices. Securing Cisco Routers The most common causes of security breaches in routers are as follows: Weak passwords— This is the most common cause of security breaches; even encrypted passwords are not secure because IOS uses a simpler and reversible encryption algorithm. Unneeded services— Unnecessary services or features can introduce related vulnerabilities or provide platforms for launching attacks. Protocol and OS vulnerabilities— Vulnerabilities in the implementation of protocols such as Hypertext Transfer Protocol (HTTP), H.323, or Simple Network Management Protocol (SNMP) can be exploited to crash the router.
