• Access Control
• The ability to do something with a computer resource (e.g., read, create, modify or delete a file,
  execute a program, or use an external connection).
• Accountability
• The ability to identify who or what was responsible for taking a particular action. Typically requires
  a logging system to record activity and authentication to verify that the user was actually the originator/instigator.
• Administration
• Tools to help enforce user access security policies.
• AES
• Advanced Encryption Standard - A newly developed standard symmetric encryption algorithm aimed to replace DES.
• AIS
• Automated Information System - any equipment of an interconnected system or subsystems of
  equipment that is used in the automatic acquisition, storage, manipulation, control, display, transmission, or reception of data and includes software, firmware, and hardware.
• Algorithm
• A mathematical function used in encryption to increase the difficulty of retrieving the information if not authorised.
• Application
• A program or system that allows you to process certain types of data.
• Antivirus
• Antivirus (or "anti-virus") software is a class of program that searches your hard drive and floppy disks
  for any known or potential viruses. The market for this kind of program has expanded because of
  Internetgrowth and the increasing use of the Internet by businesses concerned protecting their
  computer assets.
• Audit trail

  Users are less likely to attempt to circumvent security policy if they know their name will show up in an audit log.
• ATM
• Automated teller machine, a machine that bank customers use to make transactions without a human teller.
• Authentication
• Authentication is the process of determining whether someone or something is, in fact, who or what it is declared to be. In private and public computer networks (including the Internet), authentication is commonly done through the use of logon passwords. Knowledge of the password is assumed to guarantee that the user is authentic. Each user registers initially (or is registered by someone else), using an assigned or self-declared password. On each subsequent use, the user must know and use the previously declared password. The weakness in this system for transactions that are significant (such as the exchange of money) is that passwords can often be stolen, accidentally revealed, or forgotten. For this reason, Internet business and many other transactions require a more stringent authentication process. The use of digital certificates issued and verified by a Certificate Authority (CA) as part of a public key infrastructure is considered likely to become the standard way to perform authentication on the Internet. Logically, authentication precedes authorization (although they may often seem to be combined).
• Authorization

• Media stored on tapes or diskettes and maintained in an offsite location to be used to restore an automated system in the event of a disaster.
• Baseline Security
• Method of selecting security measures for implementation within a company based upon measures used in similar companies that are generally accepted to be well-run. Implementation of Baseline Security throughout a company provides a common basis for units to develop, implement and measure effective information security management and practice, and also provides confidence in inter-unit/inter-company trading. The British Standard for Information Security management, BS 7799 (now ISO 1-7799) provides a list of baseline controls which should be implemented in all circumstances, and it is salutary to see how many of these basic principles apply to the smallest of organisations, not just large companies.

  Unlike a nuisance virus or computer attack that results in a denial of service, a cyberterrorist attack is designed to cause physical violence or extreme financial harm. According to the U.S. Commission of Critical Infrastructure Protection, possible cyberterrorist targets include the banking industry, military installations, power plants, air traffic control centres, and water systems.
  Cyberterrorism is sometimes referred to as electronic terrorism or information war.
• Decryption
• The reserve process of encryption to turn scrambled data back into original form.
• Demutualization
• The process through which a member-owned company becomes shareholder-owned; frequently this is a step toward the initial public offering (IPO) of a company. Insurance companies often have the word "mutual" in their name, when they are mutually owned by their policy holders as a group. In recent years, however, there has been a strong trend for these companies to demutualize, converting to a shareholder ownership base. Worldwide, stock exchanges have offered another striking example of the trend towards demutualization, as the London Stock Exchange (LSE), New York Stock Exchange (NYSE), Toronto Stock Exchange (TSE) and most other exchanges across the globe have either recently converted, are currently in the process, or are considering demutualization.
• Distributed Denial of Service (DDOS)
• On the Internet, a distributed denial-of-service (DDoS) attack is one in which a multitude of compromised systems attack a single target, thereby causing denial of service for users of the targeted system. The flood of incoming messages to the target system essentially forces it to shut down, thereby denying service to the system to legitimate users.
  A hacker (or, if you prefer, cracker) begins a DDoS attack by exploiting a vulnerability in one computer system and making it the DDoS "master." It is from the master system that the intruder identifies and communicates with other systems that can be compromised. The intruder loads cracking tools available on the Internet on multiple -- sometimes thousands of -- compromised systems. With a single command, the intruder instructs the controlled machines to launch one of many flood attacks against a specified target. The inundation of packets to the target causes a denial of service.
  While the press tends to focus on the target of DDoS attacks as the victim, in reality there are many victims in a DDoS attack -- the final target and as well the systems controlled by the intruder.
