  • Cisco IOS XR Security
    07_1587052717_ch06.qxp 5/15/09 11:21 AM Page 159 CHAPTER 6 Cisco IOS XR Security It is important to control access to the router to prevent unauthorized or malicious use that might take the router offline or use it to launch an attack on the rest of the network. Cisco IOS XR provides the authentication, authorization, and accounting (AAA) frame- work that helps provide secure access via the logical vty and the physical tty ports. Fur- thermore, ensuing sections in this chapter discuss the concepts of task-based authorization and familiarize the user with IOS XR concepts such as admin and SDR planes as well as the uniqueness of user groups and task group configuration. Forwarding plane refers to the components involved in the various stages during packet forwarding. Forwarding plane refers not only to the flow of a packet through the router but also to the packets destined to the router. Protection of forwarding plane is important and necessitates controlling the type of traffic that traverses the router, and limiting the amount of traffic that’s destined to the router itself so that the router does not become a victim of a denial of service (DoS) attack. You might well be familiar with access control lists (ACL) and Unicast Reverse Path Forwarding (uRPF) as popular forwarding plane secu- rity features. Additionally, IOS XR has a concept of Local Packet Transport Service (LPTS). LPTS provides protection against traffic destined to the router. This type of traffic is usually related to routing protocols that typically run on the route processor (RP) of the router, though Telnet, SNMP, NTP, ping, traceroute, and various other services create traf- fic that can be destined to a router’s line card or RP CPU.

  • Memory Forensics Analysis of Cisco IOS XR 32 Bits Routers
    Memory forensics analysis of Cisco IOS XR 32 bits routers Abstract Attackers are constantly developing new techniques to bypass current security measures, and they are researching new targets to attack. The "Shadow Brokers" case illustrates that advanced attackers now target network devices such as routers. These core devices handle large amounts of data and are generally not audited by the security team, nor protected by specific security solutions, making them very interesting targets for attackers. This paper explains Cisco IOS XR routers internal, relevant to forensics analysis. As no forensics tool exists on this platform, we develop a tool for dumping the memory of the routers and another one, amnesic-sherpa, to analyze the memory dumps. Also, we demonstrate that by using an automated process based on these tools, we can determine if a router was compromised.
