An access token is a data structure that holds security information for a process to access protected objects or processes. It contains security identifiers, user privileges, and identifies its type. The token is verified by a security reference monitor before granting access to objects or processes. In computer operating systems and other software frameworks, an […]
The Network Access Point (NAP) system was developed by the National Science Foundation (NSF) to replace the NSFNet. It allowed different network service providers to exchange information and connect their networks, leading to the formation of the modern Internet. The NAPs were later replaced by Internet Exchange Points (IXPs). A network access point (NAP) is […]
Discretionary Access Control (DAC) allows select users to control program access and assign rights to different users, while mandatory access control sets restrictions by security policy administrators. DAC is flexible and easily customizable, allowing for easy changes in access rights. This limits the possibility of illegal use by unauthorized individuals. Discretionary Access Control (DAC) is […]
An online public access catalog (OPAC) allows library patrons to access information about the facility’s holdings from any computer with internet access. Patrons can also interact with their library account and request purchases. The design of catalogs is evolving, allowing for more advanced searches and navigation.

Wi-Fi Protected Access (WPA) uses encryption and authentication protocols to prevent unauthorized users from accessing wireless connections. It is commonly used in corporate and residential settings to restrict access to authorized devices. WPA eliminates the potential for unauthorized access and allows for temporary access to visitors with security codes. Wi-Fi Protected Access is a strategy […]
Internet access programs manage communication and protocols to retrieve/send information to servers. They act as a bridge between the internet and computer, with little functionality of their own. Different types of programs are used for different hardware, such as modems or wireless networks. An Internet access program is software on a computer or device that […]
A network access server provides remote access to various resources, including the internet, printers, and telecommunications systems. Users are authenticated with login credentials and a password. A NAS can connect to an ISP, join different computer networks, and provide telephony services. It is commonly used by companies with remote workers and is governed by standardized […]
Finland has made internet access a legal right, promising all citizens at least 1 Mbps of broadband access. By 2015, the goal is to guarantee 100 Mbps to all residents. More than 95% of Finns already have access to 95 Mbps or more. In contrast, 40% of US residents lack broadband access, while 30% have […]
A wireless access point broadcasts a Wi-Fi signal that mobile devices can connect to, often for free. They are found in businesses and can be created by consumers through their mobile carrier. Some are restricted for employee use and utility companies are implementing city-wide hotspots. A wireless access point, or hotspot, is a location that […]

Access point mapping, also known as war driving, is the unauthorized use of unsecured wireless LANs. GPS technology is used to locate open networks, which can be used for anything from checking email to obtaining business documents. To prevent access point mapping, businesses and individuals should use built-in security technology and set up a firewall. […]
Physical access security is important to prevent unauthorized access to IT systems. Measures include locks, biometric identification, security guards, cameras, and exterior security measures. Access control systems need to be properly secured as they can be vulnerable to hacking. Security layers can reduce the risk of a breach. Physical access security prevents people from coming […]
Rope access jobs involve working in high and hard to reach areas, with positions available in industrial safety, mountaineering, wind energy, geotechnical work, and offshore structures. Required qualifications vary by region, but generally workers need special training and certification. Companies typically supply equipment and may offer free training or certification. Experienced workers can become instructors […]
Uniform Memory Access (UMA) is a network architecture where all processors have equal access to memory. Each processor has a personal memory cache, and less programming is required. UMA is used in networks with two or more users, and standalone computers have access to uniform memory. Uniform Memory Access (UMA) is a type of network […]
Remote access allows users to connect to internal networks from a remote location and use resources hosted on the network. It requires internet access and login credentials. It benefits mobile employees, increasing productivity. Remote access can also refer to devices that allow remote operation, such as TV remotes and universal remotes. Remote access is the […]
The data access layer (DAL) is a part of a computer program that facilitates access between the program and permanent storage. It acts as an intermediary between the program and storage device, shuffling information back and forth. Programs that use a data access layer can be dependent or database agnostic. A data access layer (DAL) […]
