Overview

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.

Back cover copy 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 exposedsystems, 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. Plus, you'll get undocumented Cisco commands, security evaluation templates, and vital security tools.

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

How to Avoid Detection of Fake Serial or Cracked Operating Systems on Internet?

How to Avoid Detection of Fake Serial or Cracked Operating Systems on Internet?

Introduction

While using a duplicate or a cracked copy of operating systems or some application softwares, some time we get a message from the software vendor that "You Are Using A Duplicate Copy of XXXX Software!" and then the cracked SW or OS gets blocked or some features of the software gets blocked or the particular application software stops working! Now what to do? For solving this problem you may re-install the application software or you can re-install you OS, but if you maintain some simple steps, you may avoid this type of duplicate software detection!

What's the matter?

Actually, now-a-days, all the application software has a feature that allows updating it automatically! For this job, every time you connect to the internet, the SW connects it self to its server, so while it contacts with its server, every time it check the serial number or the registration info with the server's database! Now, the server holds two type of serial's database, one is of the original serials and another is of blacklisted serials which have detected previously by itself as fake serial! And if your serial or registration info belongs to the blacklisted database or not matched with the original database, then the software gives the message "You Are Using A Duplicate Copy of XXXX Software!"

What To Do?

Simply, you have to turn off the automatic updating feature, which is available at the 'options' of the SW! Now, here is another process to stop contacting the server of the SW, you need to re-configure your operating system's host file, which is a small database of website addresses and their IPs! To do so [In Windows] Go "My Computer -> C: -> Windows -> System32 -> Drivers -> Etc -> Open The "Host" File Using Notepad" Now, in every line, write the targeted
web address and then give a tab and write IP 127.0.0.1 - this will block this particular websites on your PC!
Now in case of operating systems, simply turn off the firewall and the automatic updating feature!
