Secure ShellThe Secure Shell Protocol (SSH Protocol) is a cryptographicnetwork protocol for operating network services securely over an unsecured network. Its most notable applications are remote login and command-line execution.
OpenBSDOpenBSD is a security-focused, free software, Unix-likeoperating system based on the Berkeley Software Distribution (BSD). Theo de Raadt created OpenBSD in 1995 by forkingNetBSD 1.0. The OpenBSD project emphasizes portability, standardization, correctness, proactive security, and integrated cryptography. The OpenBSD project maintains portable versions of many subsystems as packages for other operating systems.
Operating systemAn operating system (OS) is system software that manages computer hardware and software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, peripherals, and other resources.
Client–server modelThe client–server model is a form of messaging pattern in a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. Often clients and servers communicate over a computer network on separate hardware, but both client and server may be on the same device. A server host runs one or more server programs, which share their resources with clients.
TelnetTelnet (sometimes stylized TELNET) is a client-serverapplication protocol that provides access to virtual terminals of remote systems on local area networks or the Internet. It is a protocol for bidirectional 8-bit communications. Its main goal was to connect terminal devices and terminal-oriented processes. The name "Telnet" refers to two things: a protocol specifying how two parties are to communicate and a software application that implements the protocol as a service.

Proprietary softwareProprietary software is software that grants its creator, publisher, or other rightsholder or rightsholder partner a legal monopoly by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting their freedoms.Computer networkNetwork that allows computers to share resources and communicate with each otherMetricsAlgorithmsCentralityGroup centralityDegreeMotifClusteringDegree distributionAssortativityDistanceModularityEfficiency ModelsListsCategoriesTopicsSoftwareNetwork scientistsIn computer science, computer engineering, and telecommunications, a network is a group of communicating computers and peripherals known as hosts, which communicate data to other hosts via communication protocols, as facilitated by networking hardware.
Fork (software development)In software development, a fork is a codebase that is created by duplicating an existing codebase and, generally, is subsequently modified independently of the original. Softwarebuilt from a fork initially has identical behavior as software built from the original code, but as the source code is increasingly modified, the resulting software tends to have increasingly different behavior compared to the original.Secure channelIn cryptography, a secure channel is a means of data transmission that is resistant to overhearing and tampering. A confidential channel is a means of data transmission that is resistant to overhearing, or eavesdropping (e.g., reading the content), but not necessarily resistant to tampering (i.e., manipulating the content). An authentic channel is a means of data transmission that is resistant to tampering but not necessarily resistant to overhearing.
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.*As an Amazon Associate I earn from qualifying purchases.
