Hacking refers to attempting to gain unauthorized access to computer systems or networks. There are different types of hackers, including white hat hackers who test security systems to help organizations, black hat hackers who access systems maliciously, and gray hat hackers whose activities fall between white and black. Common types of hacking include website, email, network, password, and computer hacking through techniques like sniffing passwords, spoofing addresses, cracking encryption, brute force guessing, and exploiting poor web application coding. Organizations can help prevent hacking by employing ethical hackers to test security, not exposing passwords to untrusted sites, closing internet access when not in use, and having basic internet knowledge.
