What Is Hacking?
Hacking is employing technology and software programming knowledge to obtain unauthorized access to digital networks, systems, or data. Hacking can be conducted with either positive or detrimental intent based on the hacker’s motivation. Positive hacking, commonly called “ethical hacking,” is locating security flaws in computer networks or systems to enhance security and thwart harmful intrusion attacks. Conversely, negative hacking entails taking advantage of flaws to access data or computer systems without authorization for self-benefit, such as compromising confidential information, interrupting services, or harming the network.
