A building is an enclosure, and every breach or break-point in that poses a hazard. Security in building is a concern of extraneous sources and due to the working of systems functioning in the interior of a building. It is the state of being or feeling secure. Security concerns arise when amenities or facilities require use of extra ordinary anthropometric and physiological capacities. This could be like a fast escape, opening a jammed door, negotiating by unusual means, etc.

Openings, height related hazards, fires and other high energy exposures, biological infections, fast-moving entities pose security problems. In most cases situations become hazardous due to deficient design, misuse and ignorance. Security hazards occur due to malicious use, such as in prisons and facilities for mentally challenged patients.

Windows of all types on exterior faces are security risk. Windows bring forth two sets of fears: someone breaking in through the window and someone or something falling out of it. A grill in the window frame provides protective cover for both the fears. The chances of forceful entry from outside reduce when a tall plinth and a high sill level are provided. A window placed on extreme outside face or with none or sloping ledges assures greater security. Security and strong rooms (for arms, ornaments, bank vaults) are placed away from the external edges, or have fewer, very small, or no openings.

Glazing is a very fragile material and was avoided in domestic buildings for a very long time. A glazed window is as safe as the outside conditions are politically reassuring. The post-Industrial age saw that large glazed windows were a functional necessity in industrial plants, hospitals, railway stations and commercial buildings. The security assurance for glazed building was provided by better manned security management of the estates. Large housing and commercial estates began to have manned surveillance. Large glass shop fronts without iron grills were possible due to community awareness and common surveillance systems. Post WW II production of toughened and layered glass heightened the security assurance. Police all over the world prefer a see-through shop for security assurance. A house with light seen through a window at night is considered safer. Electronic surveillance systems now allow remote and automatic monitoring and so provide even greater security assurance.
