Antivirus
A variety of strategies are typically employed. Signature-based detection involves searching for known patterns of data within executable code. However, it is possible for a computer to be infected with new malware for which no signature is yet known. To counter such so-called zero-day threats, heuristics can be used. One type of heuristic approach, generic signatures, can identify new viruses or variants of existing viruses by looking for known malicious code, or slight variations of such code, in files. Some antivirus software can also predict what a file will do by running it in a sandbox and analyzing what it does to see if it performs any malicious actions.

Firewall
An application firewall is a form of firewall which controls input, output, and/or access from, to, or by an application or service. It operates by monitoring and potentially blocking the input, output, or system service calls which do not meet the configured policy of the firewall. The application firewall is typically built to monitor one or more specific applications or services (such as a web or database service), unlike a stateful network firewall which can provide some access controls for nearly any kind of network traffic. There are two primary categories of application firewalls, network-based application firewalls and host-based application firewalls.

Data Loss Prevention (DLP) is a computer security term referring to systems that identify, monitor, and protect data in use, data in motion, and data at rest through deep content inspection, contextual security analysis of transaction (attributes of originator, data object, medium, timing, recipient/destination and so on) and with a centralized management framework.

Taps & Aggregators
Test access ports or network taps are passive devices that enable tools such as protocol analyzers and security systems to monitor the data on a network link. Taps pass data transparently through their two network ports, while making copies of the data available on one or more monitoring ports. Aggregators are taps that copy multiple traffic streams to a single monitoring port. Port aggregators combine the traffic flowing in both directions on a network link into a single stream that is copied to the monitoring port. Link aggregators combine traffic from multiple network links or Span ports into a single stream that is copied to the monitoring port.

Wireless
is a wireless standard for connecting electronic devices. A Wi-Fi enabled device such as a personal computer, video game console, smartphone, and digital audio player can connect to the Internet when within range of a wireless network connected to the Internet. A single access point (or hotspot) has a range of about 20 meters (65 feet) indoors. Wi-Fi has a greater range outdoors and multiple overlapping access points can cover large areas. "Wi-Fi" is a trademark of the Wi-Fi Alliance and the term was originally created as a simpler name for the IEEE 802.11 standard. Wi-Fi is used by over 700 million people, there are over 4 million hotspots (places with Wi-Fi Internet connectivity) around the world, and about 800 million new Wi-Fi devices every year.

Web Filtering
Content-control software, also known as censorware or web filtering software, is a term for software designed and optimized for controlling what content is permitted to a reader, especially when it is used to restrict material delivered over the Web. Content-control software determines what content will be available. The restrictions can be applied at various levels: a government can attempt to apply them nationwide, or they can, for example, be applied by an ISP to its clients, by an employer to its personnel, by a school to its students, by a library to its visitors, by a parent to a child's computer, or by an individual user to his or her own computer.
