Natural access control is intended to deny access to crime targets and to create a perception of risks to offenders.
Access control reduces the opportunity and accessibility for crime.
Organized access control methods include the use of security guards. Windows may have protective glazing that withstands blows without breaking. Doors and window hardware may have special material and mountings that make them hard to remove or tamper with. Walls, floors, and doors may be specially reinforced in high-security areas with materials difficult to penetrate. Natural access control methods make use of spacial definition and circulation patterns.
