exploitation in denying access

In many cases, gaining access to a particular target system is impossible, exceedingly difficult, or not even desired by a hacker. At times, the goal of a hacker is simply to prevent legitimate users from accessing a website or network. This type of activity is known as denial-of-service (DoS). The purpose of conducting a DoS attack can vary. Since it is relatively simple to execute, it is often a beginner exercise for an inexperienced hacker (“newbie”, “n00b”, or “neophyte”) in the parlance) to earn some bragging rights. More experienced hackers can execute sustained DoS attacks that disrupt commercial or government servers for an extended period of time. Thus, organized groups of hackers often hold a website “hostage” and demand a ransom from the owners in exchange for halting the attack, all without ever having to gain access.
