Computer security is a branch of computer technology known as information security as applied to computers and networks. The objective of computer security includes protection of information and property from theft, corruption, or natural disaster, while allowing the information and property to remain accessible and productive to its intended users. The term computer system security means the collective processes and mechanisms by which sensitive and valuable information and services are protected from publication, tampering or collapse by unauthorized activities or untrustworthy individuals and unplanned events respectively. The strategies and methodologies of computer security often differ from most other computer technologies because of its somewhat elusive objective of preventing unwanted computer behavior instead of enabling wanted computer behavior.

The technologies of computer security are based on logic. As security is not necessarily the primary goal of most computer applications, designing a program with security in mind often imposes restrictions on that program's behavior.

Don Jones (born 1923) is an American artist and art therapist, fourth American Art Therapy Association (AATA) President, Honorary Life Member of AATA, and one of five founders of the American Art Therapy Association.

Don Jones is recognized as one of the pioneers of art therapy.^{[citation needed]} Jones’ contributions to the field of art therapy include serving in professional and community positions. In addition, as one of the five founding members of American Art Therapy Association (AATA), he was influential in the formation of the ATAA. Jones also served as president, training influential art therapists and creating permanent pieces of artwork.

Don Jones almost drowned at the age of four but was rescued and resuscitated by his older brother. Jones first started drawing after his near-drowning. He credits art with helping him overcome the traumatic experience. For 16 years, he repeatedly drew and painted boats and different forms of water. He mastered visual representation of water surfaces by that time, which helped him to process the drowning incident by re-enacting it through his art. As a teenager, Jones taught himself to paint, starting with oils. He realized during the art process that it was different from the art curriculum he learned in school. Don felt release.

Bruce Schneier ( /ˈʃnaɪər/; born January 15, 1963) is an American cryptographer, computer security specialist, and writer. He is the author of several books on general security topics, computer security and cryptography, and is the founder and chief technology officer of BT Managed Security Solutions, formerly Counterpane Internet Security, Inc.

A son of Martin Schneier, a Brooklyn Supreme Court judge, Bruce grew up in Flatbush, attending P.S. 139 and Hunter High School. After receiving a physics bachelor's degree from the University of Rochester in 1984, he went to the American University in Washington, D.C. and got his master's degree in computer science in 1988. He was awarded an honorary Ph.D from the University of Westminster in London, England in November 2011. The award was made by the Department of Electronics and Computer Science in recognition of Schneier's 'hard work and contribution to industry and public life'.

In 1994, Schneier published "Applied Cryptography", which details the design, use, and implementation of cryptographic algorithms. More recently he published "Cryptography Engineering", which is focused more on how to use cryptography in real systems and less on its internal design. He has also written books on security for a broader audience. In 2000, Schneier published Secrets and Lies: Digital Security in a Networked World. In 2003, Schneier published Beyond Fear: Thinking Sensibly About Security in an Uncertain World.
