Implement bulletproof Cisco security the battle-tested Hacking Exposed way Defend against the sneakiest attacks by looking at your Cisco network and devices through the eyes of the intruder. Hacking Exposed Cisco Networks shows you, step-by-step, how hackers target exposed systems, gain access, and pilfer compromised networks. All device-specific and network-centered security issues are covered alongside real-world examples, in-depth case studies, and detailed countermeasures. It’s all here--from switch, router, firewall, wireless, and VPN vulnerabilities to Layer 2 man-in-the-middle, VLAN jumping, BGP, DoS, and DDoS attacks. You’ll prevent tomorrow’s catastrophe by learning how new flaws in Cisco-centered networks are discovered and abused by cyber-criminals. Use the tried-and-true Hacking Exposed methodology to find, exploit, and plug security holes in Cisco devices and networks. Locate vulnerable Cisco networks using Google and BGP queries, wardialing, fuzzing, host fingerprinting, and portscanning. Abuse Cisco failover protocols, punch holes in firewalls, and break into VPN tunnels
Use blackbox testing to uncover data input validation errors, hidden backdoors, HTTP, and SNMP vulnerabilities. Gain network access using password and SNMP community guessing, Telnet session hijacking, and searching for open TFTP servers. Find out how IOS exploits are written and if a Cisco router can be used as an attack platform Block determined DoS and DDoS attacks using Cisco proprietary safeguards, CAR, and NBAR. Prevent secret keys cracking, sneaky data link attacks, routing protocol exploits, and malicious physical access. |

While computers and other devices identify each other on networks or the Internet by using unique addresses made up of numbers, humans rely on the Domain Name System (DNS), the distributed database that allows us to identify machines by name. DNS does the work of translating domain names into numerical IP addresses, routing mail to its proper
destination, and many other services, so that users require little or no knowledge of the system. If you’re a network or system administrator, however, configuring, implementing, and maintaining DNS zones can be a formidable challenge. And now, with Windows Server 2003,
an understanding of the workings of DNS is even more critical. DNS on Windows Server 20003 is a special Windows-oriented edition of the classic DNS and BIND, newly updated to document the many changes to DNS, large and small, found in Windows Server 2003. Veteran O’Reilly authors, Cricket Liu, Matt Larson, and Robbie Allen explain the whole system in terms of the new Windows Server 2003, from starting and stopping a DNS service to
establishing an organization’s namespace in the global hierarchy. Besides covering general issues like installing, setting up, and maintaining the server, DNS on Windows Server 2003 tackles the many issues specific to the new Windows environment, including the use of the dnscmd program to manage the Microsoft DNS
Server from the command line and development using the WMI DNS provider to manage the name server programmatically. The book also documents new
features of the Microsoft DNS Server in Windows Server 2003, including conditional forwarding and zone storage in Active Directory application partitions. |
