Expert Advice on Keeping Your Network Safe by Blocking Dangerous Hacker Attacks
The stories go on and on about another individual having their personal information stolen from their computer by some hacker. While it is true that hackers do get people's information, and they will keep on getting that information,
it is also true that having intrusion detection software can help. And even better, to be hacker safe intrusion prevention system is by the same software.
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.
