About Hacking? Why we need Security?

About Hacking....

In the truest sense of the word, a "hacker" is a dedicated programming expert who believes in sharing his expertise and experiences with other hackers. A hacker does not believe in vandalizing or maliciously destroying data, or in stealing data of any kind. A "cracker" is a cyber burglar or vandal - an individual or group intent on causing malicious harm to a network or computer, or to steal information beneficial to themselves like passwords, credit card numbers and the like. For ease of use, the term "hacker" is used here to refer to either a hacker or cracker, as someone who enters or tries to enter your computer or network without authorization. In other words Hackers are people who try to gain unauthorised access to your computer. This is normally done through the use of a 'backdoor' program installed on your machine. You can protect yourself from these by using a firewall and a good up-to-date anti-virus program.

Why we need Security....

In the ever changing world of global data communications, inexpensive Internet connections, and fast-paced software development, security is becoming more and more of an issue. Security is now a basic requirement because global computing is inherently insecure. As your data goes from point A to point B on the Internet, for example, it may pass through several other points along the way, giving other users the opportunity to intercept, and even alter it. It does nothing to protect your data center, other servers in your network, or a malicious user with physical access to your EnGarde system.

Security is about defense in depth. Providing physical security as well as a well-designed network, control over the users and processes on the host itself, and regular maintenance can go a long way towards providing good security.

In the most basic sense, a system is secure if it does what it's supposed to do, even if its users attempt to do something they're not supposed to do. It protects the information stored in it from being modified either maliciously or accidentally or read or modified by unauthorized users.

Consider the security of your household. Perhaps you have an alarm system, but does it work if the intruder cuts the system power? Security involves trade offs. How much is your data worth? Does it make sense to protect your system with the level of security you might find protecting Fort Knox, or would that cost more than the data itself?
