One of the most sophisticated forms of cyberattacks is session hijacking. Hackers take over network, web, or service sessions—the valid interactions of unsuspecting users—in order to gain unauthorized access to data and systems and attack an organization from the inside. The root failure is weaknesses in common protocols. To prevent these attacks, IT security professionals need to know which protocols are vulnerable and how to test their systems for exposure.
