Understanding Network Hacks: Attack and Defense with Python
Format: PDF / Kindle (mobi) / ePub
This book explains how to see one's own network through the eyes of an attacker, to understand their techniques and effectively protect against them. Through Python code samples the reader learns to code tools on subjects such as password sniffing, ARP poisoning, DNS spoofing, SQL injection, Google harvesting and Wifi hacking. Furthermore the reader will be introduced to defense methods such as intrusion detection and prevention systems and log file analysis by diving into code.
Content-Length defines the length of the content body in bytes, Content-Type the MIME type. Other important request options are Referer , that includes the URL that generated this request, Authorization , which is used by HTTP-Auth to implement login functionality and Cookie, that includes all cookies. Fig. 7.1HTTP-request-header Cookies are name/value pairs, that the server asks the client to save and resend with every request. You can read more about cookies in Sect. 7.6 about cookie
broken and has been able to be cracked in seconds since over 5 years. On average it takes an attack about 10 min executed on suboptimal signal strength from outside of buildings. Don’t use it. Reading about WEP security one always stumbles over IVs and Weak IVs. The key that WEP uses to encrypt the frames is either 64 or 128 bit long. In reality the applied key is only 40 or 104 bit, because the first 24 bit include the so called initialization vector (IV), that ensures that it is not always the
