Secure Routing Protocol for Integrated UMTS and WLAN Ad Hoc Networks

The integrated UMTS and WLAN ad hoc networks are getting more and more popular as they hold substantial advantages by next generation networks. We introduce a new secure, robust routing protocol specifically designed for next generation technologies and evaluated its performance. The design of the SNAuth_SPERIPv2 secure routing protocol takes advantage to the integrated network, maintaining Quality of Service (QoS) under Wormhole Attack (WHA). This paper compares performance of newly developed secure routing protocol with other security schemes for CBR video streaming service under WHA

Con los conocimientos obtenidos y puestos en práctica se busca obtener el desarrollo de la actividad final como prueba de habilidades, donde mediante los escenarios propuestos se coloca en habilidad los conocimientos previamente aprendidos realizando configuraciones como: IPv4 e IPv6, seguridad de switches, routing entre VLAN, el protocolo de routing dinámico RIPv2 y OSPF, el protocolo de configuración de hosts dinámicos (DHCP), la traducción de direcciones de red dinámicas y estáticas (NAT), listas de control de acceso (ACL) y el protocolo de tiempo de red (NTP) servidor/cliente, encapsulamiento PPP y su autenticación. Durante la realización de las configuraciones, se probará y registrará la red mediante el uso de comandos en la Interfaz de línea de comandos (CLI) y algunos ajustes usando la interfaz grafica de los dispositivos.The National Open and Distance University, during the learning process of the CISCO in-depth course (design and implementation of integrated LAN / WAN solutions) using the Cisco Packet Tracer simulation software, which is a program that allows us to simulate the networks, seeks to experience the different configuration parameters of a network topology. In the development of the modules CCNA1 (CCNA R&S: Introduction to Networks) and CCNA2 (CCNA R&S: Routing and Switching Essentials), the theoretical and practical bases for learning technology are obtained. With the knowledge obtained and put into practice, the aim is to obtain the development of the final activity as a test of skills, where by means of the proposed scenarios the previously learned knowledge is placed in skill, making configurations such as: IPv4 and IPv6, switch security, routing between VLANs , RIPv2 and OSPF dynamic routing protocol, dynamic host configuration protocol (DHCP), dynamic and static network address translation (NAT), access control lists (ACLs), and network time protocol ( NTP) server / client, PPP encapsulation and authentication. During the setup, the network will be tested and logged using commands in the Command Line Interface (CLI) and some settings using the graphical interface of the devices

A Security Framework for Routing Protocols

With the rise in internet traffic surveillance and monitoring activities, the routing infrastructure has become an obvious target of attack as compromised routers can be used to stage large scale attacks. Routing protocols are also subjected to various threats such as capture and replay of packets that disclose the network information, forged routing control messages that may compromise a connection by deception, disruption of an on-going connection causing DoS attacks and spreading of unauthentic routing information in the network. Presently, strong cryptographic suites and key management mechanisms (IPsec and IKE) are available to secure host-to-host data communication but none of them focus on securing routing protocols. Today's routing protocols use a shared secret to perform mutual authentication and authorization, and depend on manual keying methods. For message integrity, they either rely on some built-in or external security feature that uses the same shared secret. The KARP working group of the IETF identified that the work is required to tighten the security of the routing protocols and demonstrated that automated key management solutions are needed for increasing security. Towards this goal we propose the RPsec framework. RPsec provides a common baseline for development of KMPs for the routing protocols, supports both automated and manual key management, and overcomes the weakness of existing manual key methods

Report of the IAB Security Architecture Workshop

On 3-5 March 1997, the IAB held a security architecture workshop at Bell Labs in Murray Hill, NJ. We identified the core security components of the architecture, and specified several documents that need to be written. Most importantly, we agreed that security was not optional, and that it needed to be designed in from the beginning
