3:36 PMLEARN HACKING STEP BY STEP – INTRO
Hacker is a word that has two meanings:Traditionally, a hacker is someone who likes to tinker with software or electronic systems. Hackers enjoy exploring and learning how operate.|
, hacker has taken on a new meaning — someone who maliciously breaks into systems for personal gain. Technically, these criminals are crackers (criminal hackers). Crackers break into (crack) systems with malicious intent. They are out for personal gain: fame, profit, and even revenge. They modify, delete, and steal information, often making other people miserable.
The good-guy (white-hat) hackers don’t like being in the same category as the bad-guy (black-hat) hackers. (These terms come from Western where the good guys wore white and the bad guys wore black cowboy hats.) Whatever the case, most people give hacker a negative connotation.
Understanding the Need to Hack Your Own Systems
That’s the basis for ethical hacking.
Protecting your systems from the bad guys — and not just the generic vulnerabilities that everyone knows about — is absolutely critical. When you know hacker tricks, you can see how vulnerable your systems are.
You don’t have to protect your systems from everything. You can’t. The only protection against everything is to unplug your computer systems and lock them away so no one can touch them — not even you. That’s not the best approach to information security. What’s important is to protect your systems from known vulnerabilities and common hacker attacks.
