testing, vulnerability testing, and information security best practices. This book covers everything from establishing your hacking plan to testing your systems to plugging the holes and managing an ongoing ethical hacking program. Realistically, for many networks, operating systems, and applications, thousands of possible hacks exist. I cover the major ones on various platforms and systems. Whether you need to assess security vulnerabilities on a small home office network, a medium-sized
industrial espionage or some other form of fraud against the organization they attack. Social engineering is different from physical security exploits, such as shoulder surfing and dumpster diving, but they are related and often are used in tandem. Here are some examples of social engineering: 62 Part II: Putting Ethical Hacking in Motion ✓ False support personnel claim that they need to install a patch or new version of software on a user’s computer, talk the user into downloading the
what about the ports that can be open but shouldn’t be? Some scanning tools can test for open ports and determine whether traffic is actually allowed to pass through the firewall. 131 132 Part III: Hacking the Network Netcat Netcat (http://netcat.sourceforge.net) can test certain firewall rules without having to test a production system directly. For example, you can check whether the firewall allows port 23 (telnet) through. Follow these steps to see whether a connection can be made through

Good scanners and exploitation tools will save you a ton of time and effort that you can spend on other, more important things, such as Facebook and Twitter.

extract the aircrack programs, the cygwin Linux simulation environment, and the supporting peek files from the project URL shown earlier and you’re ready to capture packets and crack away! A longer key length, such as 128 bits or 192 bits, doesn’t make WEP exponentially more difficult to crack. This is because WEP’s static key scheduling algorithm requires that only about 20,000 or so additional packets be captured to crack a key for every extra bit in the key length. The wireless industry has
