Public security is the function of governments which ensures the protection of citizens, persons in their territory, organizations, and institutions against threats to their well-being – and to the prosperity of their communities.
To meet the increasing challenges in the public security area, responsible public institutions and organisations can tap into their own intelligence to successfully address possible threats in advance. They optimise their internal structures, use synergies, and carefully balance costs and benefits of their measures.
Public safety organizations include law enforcement, fire and emergency medical services. The public safety issues that a municipality, county, state, or federal jurisdiction might grapple with include narcotic use, trespassing, burglary, harassment, juvenile delinquency, unauthorized living, noise, littering, inappropriate social behavior, inebriation, and other quality of life issues. Generally organizations are involved in the prevention of and protection from events that could endanger the safety of the general public from significant danger, injury, or property damage, such as crimes or disasters (natural or human-made).
The latter has largely contributed to public security becoming an important political and economic issue, nationally as well as internationally. Politics, public organisations and businesses closely collaborate to guarantee public security and maintain a stable environment for economic prosperity.
Although public security significantly contributes to the attractiveness of a location, the productivity of its people, and hence the overall success of an economy, the sector frequently suffers from low budgets, limited resources, and inadequate information systems. Large events, pandemics, severe accidents, environmental disasters, and terrorism attacks pose additional threats to public security and order.
The police, federal police and border authorities nonetheless need to warrant the security of the country as a fundamental prerequisite for the domestic political ability to act. The quality and scope of potential threats have changed significantly, and the tasks and general framework for the police, federal police and border authorities have changed accordingly.
