Protection
The Secretary of the Interior’s Standards indicates that protection means “to effect the physical conditions of a property by defending or guarding it from deterioration, loss or attack, or to cover or shield the property from damage or injury.” In the case of buildings, it is generally temporary, anticipating future historic preservation treatment.

access control
The management of admission to system and network resources. It grants authenticated users access to specific resources based on company policies and the permission level assigned to the user or user group. Access control often includes authentication, which proves the identity of the user or client machine attempting to log in. See network access control, authentication, access control list and information security.antivirus program
Software that searches for viruses. Also known as a "virus scanner." As new viruses are discovered by the antivirus vendor, their binary patterns and behaviors are added to a database that is downloaded periodically to the user's antivirus program via the Web. Popular antivirus programs are Norton, McAfee, Sophos, Bitdefender, AVG and Kaspersky. Microsoft Defender is Microsoft's own antivirus software that comes with Windows, starting with Windows 8.Antivirus programs are used on all Windows machines, but most Mac users do not install them. However, as more Macs are acquired, the Mac has slowly but surely become a target of attacks, and Mac antivirus programs are being installed at a more rapid rate than in the past. See virus, quarantine, disinfect and scareware.
Multiple Detection Approaches
Early antivirus scanning matched the binary signature (pattern) of executable files against a database of known malware signatures before they were allowed to run. This "scanning" process was vastly speeded up by doing a one-time scan of all the executables in the computer and also when a new one is installed. If the executable is virus free, a checksum (hash) of its binary pattern is computed and stored in a checksum database. The next time the executable is launched by the user, its checksum is recomputed and compared with the virus-free checksum. If they match, the file was not adulterated.
Because malware may generate a unique signature each time it is downloaded to an unsuspecting user, antivirus programs also use behavior detection, which looks for suspicious activities such as copying and deleting files when launched (see behavior detection). See Symantec, McAfee, Sophos, Bitdefender, AVG, checksum, virus, polymorphic virus and Reputation-based Security.

| This is commonly used to speed up antivirus scanning, because computing and comparing an executable's checksum is considerably faster than analyzing the file each time it is loaded. |
endpoint security
(1) An umbrella term for security in the user's machine (client machine).(2) Diagnosing the status of a user's computer or mobile device when it connects to the network. Also called, "network access protection" (NAP), the security software is deployed in both the client and server side. It determines if the operating system, Web browser and other applications are up-to-date. It also checks the status of the antivirus, firewall and other security components. If a device is deemed non-compliant, it is either updated, or access to the network is declined. See network access control, lock down and vSentry.
firewall
The primary method for keeping a computer secure from intruders. A firewall allows or blocks traffic into and out of a private network or the user's computer. Firewalls are widely used to give users secure access to the Internet as well as to separate a company's public Web server from its internal network. Firewalls are also used to keep internal network segments secure; for example, the accounting network might be vulnerable to snooping from within the enterprise.In the home, a personal firewall typically comes with or is installed in the user's computer (see Windows Firewall). Personal firewalls may also detect outbound traffic to guard against spyware, which could be sending your surfing habits to a website. They alert you when software makes an outbound request for the first time (see spyware).
In the organization, a firewall can be a stand-alone machine (see firewall appliance) or software in a router or server. It can be as simple as a single router that filters out unwanted packets, or it may comprise a combination of routers and servers each performing some type of firewall processing. For more about the various firewall techniques, see firewall methods. See WAF.

| O'Reilly's "Building Internet Firewalls, 2nd Edition" by Zwicky, Cooper and Chapman is one of the best books written on Internet and Web security. It covers a huge range of firewall and related topics and should be a "must have" for anyone interested in the subject. (O'Reilly & Associates, Inc., 2000) |
information security
The protection of data against unauthorized access. Programs and data can be secured by issuing passwords and digital certificates to authorized users. However, passwords only validate that a correct number has been entered, not that it is the actual person. Digital certificates and biometric techniques (fingerprints, eyes, voice, etc.) provide a more secure method (see authentication). After a user has been authenticated, sensitive data can be encrypted to prevent eavesdropping (see cryptography).Authorized Users Can Be the Most Dangerous
Although precautions can be taken to authenticate users, it is much more difficult to determine if an authorized employee is doing something malicious. Someone may have valid access to an account for updating, but determining whether phony numbers are being entered requires a great deal more processing. The bottom line is that effective security measures are always a balance between technology and personnel management. See Parkerian hexad, information assurance, security scan, security audit, audit trail, NCSC, ICSA, access control, share-level security, user-level security and social engineering.
