Security means safety, as well as the measures taken to be safe or protected. In order to provide adequate security for the parade, town officials often hire extra guards.

A small child will sometimes latch on to a blanket or stuffed animal that gives him or her the feeling of security. Often this word is used in compounds such as a security measure, security check or security guard. The security department in a business is sometimes just called security.
