Trojan horse (computing)In computing, a trojan horse or trojan is a kind of malware that misleads users as to its true intent by disguising itself as a normal program. Trojans are generally spread by some form of social engineering. Although their payload can be anything, many modern forms act as a backdoor, contacting a controller who can then have unauthorized access to the affected device. Ransomware attacks are often carried out using a trojan.Computer securityProtection of computer systems from information disclosure, theft or damageComputer security (also cybersecurity, digital security, or information technology (IT) security) is a subdiscipline within the field of information security.

SoftwareSoftware (SW) consists of computer programs that instruct the execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware.
Logic bombA logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met. For example, a programmer may hide a piece of code that starts deleting files (such as a salary database trigger), should they ever be terminated from the company.
Computer virusA computer virus is a type of malware that, when executed, replicates itself by modifying other computer programs and inserting its own code into those programs. If this replication succeeds, the affected areas are then said to be "infected" with a computer virus, a metaphor derived from biological viruses. Computer viruses generally require a host program. The virus writes its own code into the host program.
Computer wormA computer worm is a standalone malware computer program that replicates itself in order to spread to other computers. It often uses a computer network to spread itself, relying on security failures on the target computer to access it. It will use this machine as a host to scan and infect other computers.
Client (computing)In computing, a client is a piece of computer hardware or software that accesses a service made available by a server as part of the client–server model of computer networks. The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network.

This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients or performing computations for a client. A single server can serve multiple clients, and a single client can use multiple servers.
PrivacySeclusion from unwanted attentionBanksy's One Nation Under CCTV graffiti, adjacent to an actual CCTV cameraPrivacy (UK: , US: ) is the ability of an individual or group to seclude themselves or information about themselves, and thereby express themselves selectively. The domain of privacy partially overlaps with security, which can include the concepts of appropriate use and protection of information. Privacy may also take the form of bodily integrity.
PortmanteauIn literary studies, a portmanteau, also known in linguistics and lexicography as a blend word, a lexical blend, or simply a blend, is a word formed by combining the meanings and parts of the sounds of two or more words. English examples include smog, coined by blending smoke and fog, and motel, blending motor (or motorist) and hotel.pay-per-installRelated word or term.malwareRelated word or term.*As an Amazon Associate I earn from qualifying purchases.
