Refers to a legal concept where a property owner or manager fails to provide adequate security measures to prevent foreseeable harm to individuals on their premises. This typically arises in cases where someone is harmed due to criminal activity such as assault, robbery, or vandalism, which could have been prevented or mitigated with appropriate security measures. Examples of negligent security might include insufficient lighting, broken locks, lack of security personnel, or failure to monitor surveillance
cameras. Victims of crimes on negligently secured premises may have grounds to seek compensation for their injuries and damages under premises liability law.
