Here is the first book to focus solely on Cisco network hacking, security auditing, and defense issues. Using the proven Hacking Exposed methodology, this book shows you how to locate and patch system vulnerabilities by looking at your Cisco network through the eyes of a hacker. The book covers device-specific and network-centered attacks and defenses and offers real-world case studies.
Harden perimeter routers with Cisco firewall functionality and features to ensure network security
* Detect and prevent denial of service (DoS) attacks with TCP Intercept, Context-Based Access Control (CBAC), and rate-limiting techniques
* Use Network-Based Application Recognition (NBAR) to detect and filter unwanted and malicious traffic
* Use router authentication to prevent spoofing and routing attacks
* Activate basic Cisco IOS filtering features like standard, extended, timed, lock-and-key, and reflexive ACLs to block various types of security threats and attacks, such as spoofing, DoS, Trojan horses, and worms
* Use black hole routing, policy routing, and Reverse Path Forwarding (RPF) to protect against spoofing attacks
* Apply stateful filtering of traffic with CBAC, including dynamic port mapping
* Use Authentication Proxy (AP) for user authentication
* Perform address translation with NAT, PAT, load distribution, and other methods
* Implement stateful NAT (SNAT) for redundancy
* Use Intrusion Detection System (IDS) to protect against basic types of attacks
* Obtain how-to instructions on basic logging and learn to easily interpret results
* Apply IPSec to provide secure connectivity for site-to-site and remote access connections
* Read about many, many more features of the IOS firewall for mastery of router security
The Cisco IOS firewall offers you the feature-rich functionality that you’ve come to expect from best-of-breed firewalls: address translation, authentication, encryption, stateful filtering, failover, URL content filtering, ACLs, NBAR, and many others. Cisco Router Firewall Security teaches you how to use the Cisco IOS firewall to enhance the security of your perimeter routers and, along the way, take advantage of the flexibility and scalability that is part of the Cisco IOS Software package.
Each chapter in Cisco Router Firewall Security addresses an important component of perimeter router security. Author Richard Deal explains the advantages and disadvantages of all key security features to help you understand when they should be used and includes examples from his personal consulting experience to illustrate critical issues and security pitfalls. A detailed case study is included at the end of the book, which illustrates best practices and specific information on how to implement Cisco router security features.
Whether you are looking to learn about firewall security or seeking how-to techniques to enhance security in your Cisco routers, Cisco Router Firewall Security is your complete reference for securing the perimeter of your network.
This book is part of the Networking Technology Series from Cisco Press, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.
A Cisco troubleshooting methodology. It includes coverage of: how to create, operate and use Cisco Access lists; how to secure a network when access occurs via a Cisco Router; and the TCP/IP Protocol and its use with Cisco routers. There are a number of security discussions too, and these include: public network and private network security threats and how to prevent them; how firewalls and proxy servers can be used as a first line of defence; how to configure Cisco Routers to accept only specific recognized incoming packets; using the Cisco PIX Firewall and the Centri firewall; and how to use the special security features built into Cisco routers.

Divided into four parts, LAN Switch Security provides you with steps you
can take to ensure the integrity of both voice and data traffic
traveling over Layer 2 devices. Part I covers vulnerabilities in Layer 2
protocols and how to configure switches to prevent attacks against those
vulnerabilities. Part II addresses denial-of-service (DoS) attacks on an
Ethernet switch and shows how those attacks can be mitigated. Part III
shows how a switch can actually augment the security of a network
through the utilization of wirespeed access control list (ACL)
processing and IEEE 802.1x for user authentication and authorization.
Part IV examines future developments from the LinkSec working group at
the IEEE. For all parts, most of the content is vendor independent and
is useful for all network architects deploying Ethernet switches.
After reading this book, you will have an in-depth understanding of LAN
security and be prepared to plug the security holes that exist in a
great number of campus networks.
- Use port security to protect against CAM attacks
- Prevent spanning-tree attacks

In the Age of Enlightenment the German philosopher Immanuel Kant encouraged people to use their own mind as the basis for reasoning instead of following dogmatic religious rules - Sapere aude! (dare to know!) - Today wireless communication networks are increasingly becoming aware of the conditions of its their component parts and surrounding environment. Cognition, a continuous process involving sensing, reasoning, understanding and reacting, can be applied to wireless networks in order to adapt the system to the highly dynamic wireless ecosystem. The ultimate goals are to enhance the efficiency in the use of radio resources as well as to improve both link and network performance. This book presents a detailed overview of a rapidly emerging topic in modern communications: cognitive wireless networks. The key aspects of cognitive and cooperative principles in wireless networks are discussed in this book. Furthermore, Cognitive Wireless Networks advocates the concept of breaking up the cellular communication architecture by introducing cooperative strategies among wireless devices. Cognitive wireless networking is the key to success in handling the upcoming dynamic network configurations and exploiting this cross-over to the fullest extent.
As wireless networks become pervasive, highly populated and increasingly complex, the essential preconditions for exploiting rich interactions among mobile devices are better fulfilled. Today, these trends are giving rise to new communications paradigms making use of cooperation and cognition as the main underlying principles. Cognition, together with its complementary principle cooperation, confer to the wireless networks some degree of consciousness or understanding about their own existence, such as internal structure, capabilities, relationships to the outside world, limitations, current use of radio resources and many more. Current wireless networks are aware of their surrounding environment to a very limited extent, but in future wireless networks this capability will be highly developed, as a consequence of exploiting jointly cooperative and cognitive principles. Especially for cooperative wireless networks, where the communication scenario is highly dynamic, the mobile devices need to adapt their capabilities in a flexible manner, taking advantage of cognitive principles.
