<span class="mw-page-title-main">Solitary confinement</span> Strict form of imprisonment

Solitary confinement is a form of imprisonment in which an incarcerated person lives in a single cell with little or no contact with other people. It is a punitive tool used within the prison system to discipline or separate incarcerated individuals who are considered to be security risks to other incarcerated individuals or prison staff, as well as those who violate facility rules or are deemed disruptive. However, it is also used as protective custody on incarcerated individuals whose safety is threatened by others in order to separate them from the general prison population.

Evin Prison is a prison located in the Evin neighborhood of Tehran, Iran. The prison has been the primary site for the housing of Iran's political prisoners since 1972, before and after the Islamic Revolution, in a purpose-built wing nicknamed "Evin University" due to the number of students and intellectuals housed there. Evin Prison has been accused of committing "serious human rights abuses" against its political dissidents and critics of the government.

chroot is an operation on Unix and Unix-like operating systems that changes the apparent root directory for the current running process and its children. A program that is run in such a modified environment cannot name files outside the designated directory tree. The term "chroot" may refer to the chroot(2) system call or the chroot(8) wrapper program. The modified environment is called a chroot jail.

Incarceration in the United States is one of the primary means of punishment for crime in the United States. In 2023, over five million people are under supervision by the criminal justice system, with nearly two million people incarcerated in state or federal prisons and local jails. The United States has the largest known prison population in the world. Prison populations grew dramatically beginning in the 1970s, but began a decline around 2009, dropping 25% by year-end 2021.

Linux-VServer is a virtual private server implementation that was created by adding operating system-level virtualization capabilities to the Linux kernel. It is developed and distributed as open-source software.

A military prison is a prison operated by a military. Military prisons are used variously to house prisoners of war, unlawful combatants, those whose freedom is deemed a national security risk by the military or national authorities, and members of the military found guilty of a serious crime. There are two types: penal and confinement-oriented, where captured enemy combatants are confined for military reasons until hostilities cease. Most militaries have some sort of military police unit operating at the divisional level or below to perform many of the same functions as civilian police, from traffic-control to the arrest of violent offenders and the supervision of detainees and prisoners of war.

The jail mechanism is an implementation of FreeBSD's OS-level virtualisation that allows system administrators to partition a FreeBSD-derived computer system into several independent mini-systems called jails, all sharing the same kernel, with very little overhead. It is implemented through a system call, jail(2), as well as a userland utility, jail(8), plus, depending on the system, a number of other utilities. The functionality was committed into FreeBSD in 1999 by Poul-Henning Kamp after some period of production use by a hosting provider, and was first released with FreeBSD 4.0, thus being supported on a number of FreeBSD descendants, including DragonFly BSD, to this day.

OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, called containers, zones, virtual private servers (OpenVZ), partitions, virtual environments (VEs), virtual kernels, or jails. Such instances may look like real computers from the point of view of programs running in them. A computer program running on an ordinary operating system can see all resources of that computer. However, programs running inside of a container can only see the container's contents and devices assigned to the container.

The Angola Three are three African-American former prison inmates who were held for decades in solitary confinement while imprisoned at Louisiana State Penitentiary. The latter two were indicted in April 1972 for the killing of a prison corrections officer; they were convicted in January 1974. Wallace and Woodfox served more than 40 years each in solitary, the "longest period of solitary confinement in American prison history".

authbind is an open-source system utility written by Ian Jackson and is distributed under the GNU General Public License. The authbind software allows a program that would normally require superuser privileges to access privileged network services to run as a non-privileged user. authbind allows the system administrator to permit specific users and groups access to bind to TCP and UDP ports below 1024. Ports 0 - 1023 are normally privileged and reserved for programs that are run as the root user. Allowing regular users limited access to privileged ports helps prevent possible privilege escalation and system compromise if the software happens to contain software bugs or is found to be vulnerable to unknown exploits.

<span class="mw-page-title-main">Prison</span> Institution in which people are legally physically confined

A prison, also known as a jail, gaolpenitentiary, detention center, correction center, correctional facility, or remand center, is a facility where people are confined against their will and denied a variety of freedoms under the authority of the state, generally as punishment for various crimes. Authorities most commonly use prisons within a criminal-justice system: people charged with crimes may be imprisoned until their trial; those who have pled or been found guilty of crimes at trial may be sentenced to a specified period of imprisonment.

<span class="mw-page-title-main">Solitary confinement in the United States</span> Form of strict imprisonment in the United States

In the United States penal system, upwards of 20 percent of state and federal prison inmates and 18 percent of local jail inmates are kept in solitary confinement or another form of restrictive housing at some point during their imprisonment. Solitary confinement (sometimes euphemistically called protective custody, punitive segregation (PSEG) or room restriction) generally comes in one of two forms: "disciplinary segregation," in which inmates are temporarily placed in solitary confinement as punishment for rule-breaking; and "administrative segregation," in which prisoners deemed to be a risk to the safety of other inmates, prison staff, or to themselves are placed in solitary confinement for extended periods of time, often months or years.
