Why You Need Intrusion Detection

Doors can be opened to hackers in varied ways. Two of the most common ways by which they can gain access to your computer is simply through emails, or Web pages that you visit that have spyware, or trojans (a file which looks innocent, but actually will later open doors to a hacker) attached to them. Other ways are robot spiders sent out over the Internet to find unprotected computers, and open doors. Some say that every computer attached to the Internet may be attacked by such a spider as many as 50 times each day. So, if you do not have an intrusion prevention system in place, up-to-date, then you may have regular unexpected visitors - and you may not even know it. Others say that 9 out of 10 computers have some sort of spyware, or malware on them. Could you be one of them? This article will show you what is available on the market for your protection - and much of it can be obtained for free.

The spider robots work automatically - looking for and identifying computers on the Internet that have doors, or ports, open to them. This information is then reported back to the hacker - knowing which computers to target - and which port to use. For this reason, every now and then, Microsoft will come out with a new patch for Windows, in order to close some faulty door that hackers have discovered and been using.

What Is Intrusion Detection?

Network Intrusion detection software is a must-have these days. Each company's software will vary somewhat (for copyright and originality purposes), but you do need one for your own network, or home computer. It differs from a firewall in that the purpose of a firewall is to stop unauthorized external contacts with your system. These offer hacker prevention largely for contacts from outside the network. Most of these will now notify the owner or network controller of intrusion attempts. Network intrusion detection systems, on the other hand, will give you warnings about events that take place within the network itself.

The second source is face to face reunions. Get into the internet and search for any hacker's meeting in your vicinity. You will be surprised to find that they meet quite regularly. Of course, do not expect to find a Matrix kind of reunion. This is serious, professional people that pay their rent by hacking. Drop by and make some questions on hacking tutorials.

What Is The Hackers Bible?

The hacker's bible has two possible sources, depending on whom do you ask. For some people, it is none other but the magazine 2600: The Hacker Quarterly. This magazine was created by Emmanuel Goldstein, and it focuses on aspects of different technologies. For example, it covers telecommunication devices as well as computers.

The magazine gives to its readers grey hacker's material. That means that it gives them information on how to augment the capacities of any electronic apparatus, such as a cell phone. This neutral posture is different to white hacking (were a hacker uses his abilities for a good cause, like detecting the vulnerabilities of a network) and black hacking (were a hacker uses his knowledge for selfish purposes, like creating a hotmail hacking guide).

The other Hacker's Bible is the Jargon File. This document is a glossary of hacker slang that has been collected since 1975, from the old days of the Arpanet (the precursor of the Internet).
