Security

For other uses, see Security (disambiguation).

Security means to prevent dangers or losses. In general, security is similar to safety. The difference between the two is that security cares more than general safety about dangers from the outside.^[1][2]

Airports and banks usually have a lot of security measures. Prison security is used mainly to stop prisoners from escaping. It is also used to stop prisoners from harming prison employees or other prisoners.

Maximum security is found in or around prisons or other types of places where people need to be kept in or kept out. It is the highest security level for a building or area.

The term is also used to refer to acts and systems whose purpose may be to provide security (security company, security police, security forces, security service, security agency, security guard, cyber security systems, security cameras, remote guarding). Security can be physical and virtual.^[3][2][4]
