What is meant by the term Hacker? What do they and how?
A hacker can be anybody who uses their knowledge of computer coding to buy pass security measures on a computer, device or network. Early on viruses had various utilities and were engineered mostly by people in the computer science industry.
College students created viruses for research projects in order to help further their studies and fine-tune their coding skills. Hackers are generally categorized by the type of metaphorical hat they wear Whitehat, Greyhat, Blackhat, the term comes from the old spaghetti westerns where the bad guys wears the black cow boy hat and the good guy wears a white hat.
There are two main things that determine the type of hacker you dealing with, their motivations and whether or not they breaking the law. If we didn’t have white hat hackers seeking out threats and vulnerabilities before the Blackhats can find them then there probably would be a lot more cybercrime than there is now.
You shouldn’t worry unnecessarily about hacking programs. They’re quite rare on personal computers. It’s network managers who lose sleep over them.
The exclusion is if you run an everlasting (always-on) Internet connection, especially a broadband cable connection or DSL. Hackers just love to colonize these connections because they’re so useful. If you’ve got one of these you must install extra security like Norton Internet Security. Your service provider will be aware of the risk and should offer you advice on what kind of security you need.
