Hackers are attackers outside of an organization who exploit security weaknesses in computer systems or networks to gain unauthorized access to information, cause mischief, or make changes to files, settings, or systems. Hackers have become increasingly sophisticated over the years, and many are experts on a variety of computer systems and software.
With the increase in cyberattacks and data security lapses, many organizations have changed their overall approach to data security and are taking a risk-based approach to data security.
