 "Security is
protection from, or resilience against, potential harm
(or other unwanted coercion). Beneficiaries (technically referents)
of security may be persons and social groups, objects and institutions,
ecosystems, or any other entity or phenomenon vulnerable to unwanted
change. Security mostly refers to protection from hostile forces,
but it has a wide range of other senses: for example, as the absence of
harm (e.g., freedom
from want); as the presence of an essential good (e.g., food
security); as resilience against
potential damage or harm (e.g. secure foundations); as secrecy (e.g., a secure
telephone line); as containment (e.g., a secure
room or cell);
and as a state of mind (e.g., emotional
security).Security is both a feeling and a state of reality. One
might feel secure when one is not actually so; or might feel insecure
despite being safe. This distinction is usually not very clear to
express in the English language.]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."
