TCP/IP model

The TCP/IP Model separates networking functions into discrete layers. Each layer performs a specific function and is transparent to the layer above it and the layer below it.The TCP/IP model is one of the two most common network models, the other being the OSI Model.
The TCP/IP network model breaks down into four (4) layers:

• Application Layer
• Transport Layer
• Internet Layer
• Network Access Layer

OSI model--open system interconnect

The Open Systems Interconnect (OSI) model has seven layers.The layers are stacked this way:

• Application
• Presentation
• Session
• Transport
• Network
• Data Link
• Physical

hiding data behind images.

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 disk ) with bits of different, invisible information. This hidden information can be plain text cipher text or even images.

Intrusion detection system

Intrusion Detection System (IDS)
A computer intrusion is the number of events that breaches the security of a system. Such number of events must be detected in proactive manner in order to guarantee the confidentiality, integrity and availability of resources of a computer system. An intrusion into an information system is a malicious activity that compromises its security (e.g. integrity, confidentiality, and availability) through a series of events in the information system. For example intrusion may compromise the integrity and confidentiality of an information system by gaining root level access and then modifying and stealing information. Another type of intrusion is denial-of-service intrusion that compromises the availability of an information system by flooding a server with an overwhelming number of service requests to the server over short period of time and thus makes services unavailable to legitimate users. According to D. Yang, A. Usynin & W. Hines, they describe intrusion and intrusion detection as: "Any action that is not legally allowed for a user to take towards an information system is called intrusion and intrusion detection is a process of detecting and tracing inappropriate, and incorrect, or anomalous activity targeted at computing and networking resources".

john the ripper(paswork cracking tool of linux)

John The Ripper:

Hello, and welcome to my guide on using John The Ripper. Today we will be cracking our own Linux password. Now before you get all jumpy and excited about what you are going to learn, let me just say this- THE CAPABILITIES OF ANY PASSWORD CRACKING TOOL ARE ONLY AS GOOD AS YOUR WORDLIST. In other words, if you have a wordlist with 5 words in it, don't expect to crack anything. It would be like trying to drive a car without a motor. If you have no idea what a wordlist is, then I'll tell you- a wordlist, or a dictionary file, is merely a .txt or .lst (these are usually the file formats) file with a bunch of words in it. On every line of the file there is only one word. Then on the next line, there is another word. Parsing these kinds of files is easy- any high level programming/scripting language can usually due this by using the .readline() method or something similar, then replacing the line that was just read with a .replace() method, or something similar

download youtube videos without any software

How to download Youtube videos on any OS without any Software

You can download the Youtube videos easily and for free without any software.
Just go to KeepVid ,savevid and then just type in or copy the Uniform Resource Locator or the URL of the video you want to download and then click on Download.

You will be shown with various formats in which you can download the specific video. You just need to select one and then the download will start!

Just remember that if your browser asks you for the permission to run the Java Applet, then, say yes.

In some cases you might not be able to download the video(just an assumption), if it happens then you need to try again after some time. If the problem still persists, then, I can't help it! :-)


I hope this was useful!

techniques to hack

There are some techniques through which you can be easily hack.So little knowledge about the techniques can prevent you from being hacked.

 Vulnerability scanner

A vulnerability scanner is a tool used to quickly check computers on a network for known weaknesses. Hackers also commonly use port scanners. These check to see which ports on a specified computer are "open" or available to access the computer, and sometimes will detect what program or service is listening on that port, and its version number. (Note that firewalls defend computers from intruders by limiting access to ports/machines both inbound and outbound, but can still be circumvented.)
