What IS IP Spoofing

Image
The term IP (Internet Protocol) address spoofing refers to the creation of IP packets with a forged (spoofed) source IP address with the purpose of concealing the identity of the sender or impersonating another computing system. Why it works ? IP-Spoofing works because trusted services only rely on network address based authentication. Since IP is easily duped, address forgery is not difficult. The main reason is security weakness in the TCP protocol known as sequence number prediction. How it works ? To completely understand how ip spoofing can take place, one must examine the structure of the TCP/IP protocol suite. A basic understanding of these headers and network exchanges is crucial to the process. Internet Protocol (IP) : It is a network protocol op...

What is ISDN? Part 1

ISDN, which stands for integrated services digital network, is a system of digitizing phone   networks which has been in the works for over a decade. This system allows audio, video,   and text data to be transmitted simultaneously across the world using end-to-end digital   connectivity. The original telephone system used analog signals to transmit a signal across telephone wires. The voice was carried by modulating an electric current with a waveform from a microphone. The receiving end would then vibrate a speaker coil for the sound to travel back to the ear through the air. Most telephones today still use this method. Computers, however, are digital machines. All information stored on them is represented by a bit, representing a zero or a one. Multiple bits are used to represent characters, which then can represent words, numbers, programs, etc. The analog signals are just varying voltages sent across the wires over time. Digital signals are represented and transmit...

Steganography

Image
-: Steganography :- The art and science of hiding information by embedding messages within other, seemingly harmless messages. Steganography works by replacing bits of useless or unused data in regular computer files (such as graphics, sound, text, HTML, or even floppy disks ) with bits of different, invisible information. This hidden information can be plain text, cipher text, or even images. Some common files used for hiding the data are .jpeg, .bmp, .jpg, .bmp, .pdf, .mp3, .wav, .gif, etc. The following example gives detailed overview on how data can be hide by steganography :- The tool used in this example is "S-Tools". Download S-Tool.zip (273 KB) 1) Prepare the secret file that you want to hide (eg. '.txt') 2) Launch the st...
