The Loss Prevention Standard (LSP 2082 : Issue 1.0), published by BRE Global in 2017, defines security as a: ‘State of being free from harm or fear of criminal activity.’ It defines security risk as: ‘The likelihood that a threat will be realised, together with a measure of the potential consequences associated with the realisation of the threat.’

It defines physical security as: 'A system of controls used to protect an organisation, its facilities and other assets (physical and cyber) from physical threats.'

For business and home owners, security can be very important. As well as the security of physical property it is also important to protect equipment, staff, visitors, and information. Security can also be an important consideration on construction sites.

Access control is the selective restriction of access to a particular place, building, room, resource or installation. To gain access to a restricted location an individual generally needs to have authorisation or to be given permission to enter by someone that already has authorisation. Perimeter security can be used to prevent intruders from penetrating a defined boundary between land, buildings or parts of buildings and gaining access to protected people, property or assets.

With regard to building regulations, Approved Document Q requires that reasonable provision is made to resist unauthorised access to new dwellings or to any part of a building from which access can be gained to a flat within that building. For more information, see Approved Document Q.

It can also refer to cyber security against cyber attacks or data breaches which poses an ever-greater risk with the emergent technologies of the Internet of Things and Big Data.

A security consultant can act as an adviser for a building owner, occupant or property developer in relation to the design and incorporation of the security solutions. Clients typically require security consultants to advise on potential security threats and potential breaches, and to create contingency protocols to safeguard their organisation or assets. For more information, see Security consultant.

The term ‘security’ can also be used in an economic context, i.e. ‘financial security’, meaning that a project has secure and adequate funding to be able to proceed. It can also refer to leaseholds, i.e. ‘security of tenure’, whereby a tenant has certain rights to continue occupying a property once the original lease has come to an end. For example, most tenants of commercial premises with a lease of more than six months, or if they have been in occupation for more than twelve months, have security of tenure.
