What Is Hacking?
Hacking is a growing field that equips cybersecurity professionals to test and analyze online security systems. These experts often find and recommend ways to improve an organization’s ability to prevent data theft, financial fraud, or regulatory penalties. Cybersecurity professionals who specialize in ethical hacking can help companies protect their customers’ privacy and ensure compliance with industry security frameworks like PCI DSS, HIPAA, and GDPR.
Many people think of software when they hear about Hacking, and for good reason: controlling the brain or consciousness of a device (like a computer) allows an attacker to lock out the user, steal data, or cause havoc. But hardware hacking can be equally dangerous, requiring onsite access to a device and the ability to bypass its built-in protections. Hardware attacks also require specialized tools that are expensive, difficult to obtain, and delicate to use.
A more sophisticated method of attacking a device is to perform a side-channel attack. This involves observing how the device works in order to gain a more precise understanding of its modus operandi and vulnerabilities. For example, this might involve timing a program execution, analyzing acoustic feedback from failed executions, or gauging the amount of power consumed when the device processes certain types of information.
Achieving these goals requires a unique mix of skills and personality traits. Curiosity and Research Drive: Successful ethical hackers love to ask “what if” questions about the technologies they investigate and explore how they work below the surface level. Persistence Through Challenges: Security testing frequently encounters challenges, and the ability to continue methodically trying different techniques without getting frustrated is a key distinguishing trait of effective ethical hackers.
