The term "need to know", when used by government and other organizations (particularly those related to the military or espionage), describes the restriction of data which is considered very sensitive. Under need-to-know restrictions, even if one has all the necessary official approvals (such as a security clearance) to access certain information, one would not be given access to such information, or read into a clandestine operation, unless one has a specific need to know; that is, access to the information must be necessary for the conduct of one's official duties.
As with most security mechanisms, the aim is to make it difficult for unauthorized access to occur, without inconveniencing legitimate access. Need-to-know also aims to discourage "browsing" of sensitive material by limiting access to the smallest possible number of people.
The Battle of Normandy in 1944 is an example of a need-to-know restriction. Though thousands of military personnel were involved in planning the invasion, only a small number of them knew the entire scope of the operation; the rest were only informed of data needed to complete a small part of the plan. The same is true of the Trinity project, the first test of a nuclear weapon in 1945.
"Need To" is a song written and recorded by American nu metal band Korn for their self-titled debut album. It was released as the album's second single in April 1995.
The song features elements of an older Korn song, "Alive", which was found on their demo tape, Neidermeyer's Mind. "Alive" was eventually reworked and re-recorded for the band's sixth studio album, Take a Look in the Mirror.
The song was performed frequently during the band's early shows. After several years of being absent from the setlist, it returned as part of the song "Alive" during the 2003 Back 2 Basics Tour. It was also played during the 2006 See You on the Other Side Tour within a medley. The song was part of the band's 2010 Ballroom Blitz Tour setlist, leading into "Coming Undone".
Staind covered this song during a live performance on the 2000 Sick and Twisted Tour which also featured Korn and Mindless Self Indulgence.
Mark William Calaway (born March 24, 1965) is an American professional wrestler better known by his ring name The Undertaker. He is signed to WWE and is the company's most tenured competitor. Calaway began his wrestling career with World Class Championship Wrestling (WCCW) in 1984. He joined World Championship Wrestling (WCW) as "Mean" Mark Callous in 1989. When WCW did not renew Calaway's contract in 1990, he signed with the World Wrestling Federation in October and, after shortening his name from Kane the Undertaker to simply The Undertaker, has remained with the company since.
The Undertaker has two contrasting personas. The first is the role of The Deadman, an undead, occult-like figure, which has consisted of many different styles. He debuted his original Deadman persona during his own on-camera debut at Survivor Series (1990). At this event, the Undertaker was clad as a Western mortician. Next, in October of 1998, the Undertaker appeared as the leader of the Ministry of Darkness (with similar apparel). Since WrestleMania XX, the Undertaker has appeared as a hybrid version of the Deadman character, using elements of the previous Deadman incarnations.
