Security police protect their agency's facilities, properties, personnel, users, visitors and operations from harm and may enforce certain laws and administrative regulations. Most security police have at least some arrest authority. The law enforcement powers of security police vary widely, in some cases limited to those of private persons yet in others amounting to full police powers equivalent to state, provincial, or local law enforcement.
As distinct from general law enforcement, the primary focus of security police is on the protection of specific properties and persons. This causes some overlap with functions normally performed by security guards. However, security police are distinguished from guards by greater authority, often higher levels of training, and correspondingly higher expectations of performance in the protection of life and property.
In other countries, 'security police' is the name given to the secret security and intelligence services charged with protecting the State at the highest level, including responsibilities such as personal protection of the head of state, counter-espionage, and anti-terrorism.
Types of security police and similar organizations 
Security police may include:
- Campus police, who are often hired and sworn in as state law enforcement officers, such as the Los Angeles School Police Department or City University of New York Public Safety Department
- Housing police, such as the New York City Housing Authority Police Department, who protect publicly owned housing or "housing projects"
- Airport police such as the Los Angeles Airport Police
- Hospital police such as the New York City Department of Health and Hospitals Police
- Park police, with full state police officer powers such as the New York State Park Police, who primarily protect the often vast properties of their employing agency
- Certain federal police agencies such as the U.S. Capitol Police, whose officers are sworn in as federal law enforcement officers with the duty to provide police and security services to federally owned buildings
- Capitol police, who protect state properties such as legislative and executive buildings, which can also include executive protection functions
- County police, such as the former Los Angeles County Office of Public Safety, who provide full, limited or restricted services to local governments
- Special police, in the protection of public properties, such as the United States Holocaust Memorial Museum which is protected by sworn Special Police Officers as authorized by D.C. Code, § 4-114 (1981)
- Court officers, such as New York State Court Officers, who provide police and security services at court houses
- Company police to provide security police services on company or private property by contract, where local law permits private organizations to contract for police powers; this for example includes railway police
All security police derive their authority from two sources:
- the laws of their nation, territory and/or municipality
- the property rights of their employing or contracting agency or activity, which may be public or private or a mixture of both
These powers might include the power to detain, arrest, investigate criminal offenses, carry weapons, employ force, and/or take other actions to protect life and property beyond that of the ordinary citizen. One key distinction is between "sworn" (or bound by oath or affirmation to uphold the laws even at personal risk), and "non-sworn" or "civilian" who are ordinary employees with normal obligations to an employer.
Some security police are full-fledged peace officers with the same powers as regular police. Others have enhanced powers which are limited by law to the properties they protect, or a specified radius or distance. In some cases these powers are expanded by a Memorandum of Understanding or other legal document where other policing agencies delegate additional powers to enforce local law.
Some security police have the more limited powers of security guards in compliance with the laws of their jurisdiction.
These distinctions are of particular importance to security police and their employers.

The Polizei beim Deutschen Bundestag (Polizei DBT, commonly known as Bundestagspolizei) is the smallest and least known police agency in Germany. It is responsible for the protection of the premises of the Bundestag in Berlin.

There are ten companies whose employees are sworn in as constables under section 79 of the Harbours, Docks, and Piers Clauses Act 1847. As a result, they have the full powers of a constable on any land owned by the harbour, dock, or port and at any place within one mile of any owned land. Additionally, there are also some forces created by specific legislation such as the Port of Tilbury Police (Port of London Act 1968), Mersey Tunnels Police (County of Merseyside Act 1989) and the Epping Forest Keepers (Epping Forest Act 1878), Kew Constabulary (section 3 of the Parks Regulation Act 1872).

United States 
In the United States, the laws concerning peace officers vary widely from state to state within a larger federal system. Each state legislature with approval from the governor has the ability to modify the powers of peace officers in their state through legislation.
Most, if not all, of the federal government's non-land management agency uniformed police officers are security police who primarily serve to protect federal property and personnel. An example would be the Federal Protective Service who protect federal buildings. See Federal law enforcement in the United States for a list of US Government security police forces.
By States 
Some major cities such as Washington DC, Los Angeles, San Francisco and Boston have a security police service separate from their city police. These may be employees of a public agency or private contractors.
The complexity of special policing and special police authority is illustrated by these examples, which are not meant to be exhaustive.
In California, peace officer powers are granted by the California Penal Code under a number of different code sections. Cities, counties and special districts are authorized to form their own law enforcement agencies. Peace officer training is regulated by a state agency, Peace Officer Standards and Training or POST. This training can consist of as little as a 40 hour PC 832 course (for park rangers, probation officers or fire investigators who might make an arrest in the course of their duties), or as much as a 700 hour POST Basic Academy (for entry level peace officers).
Security guards (including off duty peace officers) may only carry firearms in private employment if licensed by the state licensing authority, the Bureau of Security and Investigative Services. Persons regularly employed by public agencies as security guards, however, may be exempt from BSIS regulation, if they have completed POST-certified training in accordance with PC 832 or other Penal Code sections. However, security guards employed by a private employer are still regulated by BSIS even though the client may be a public agency.

Los Angeles 
In the Los Angeles metropolitan area, there are numerous examples of security police with different levels of authority and responsibility.
- Los Angeles County Sheriff's Department - The Los Angeles County Sheriff's Department employs Security Assistants (Security Officer I) and Security Officers (Security Officer II) who assist Deputy Sheriff's in the protection of various county government facilities. The LASD absorbed the Los Angeles County Office of Public Safety Police on June 30, 2010.

Security Officers assigned to the Community College Division provide campus security to the county's community colleges. Additionally Security Officers may also be assigned to provide security at other county facilities.
- Sheriff's Security Officers in compliance with applicable laws and regulations, such as peace officer ("POST") training, have limited peace officer powers while on duty and are outside the authority of the state security guard licensing agency, the Bureau of Security and Investigative Services (BSIS) with respect to their work for the County.
- Los Angeles County Metropolitan Transportation Authority - Los Angeles County Metropolitan Transportation Authority Transit Security Officers are under the full Los Angeles County Sheriff's Department/Transit Services Bureau supervision, uniformed, non-sworn personnel, who serve the MTA (Metro) by providing security for critical transportation infrastructure and internal revenue protection. Transit Security Officers undergo a selection process that is similar to that for police (including an identical background investigation, as well as a psychological review and physical agility test), as well as a 600-hour internal training program, which includes completion of (BSIS) Guard and Firearm training.
Many Transit Security Officers have advanced training to serve in specialized functions, such as that of a dispatcher, K-9 handler, rangemaster, or armorer. Furthermore, several officers represent the department in IPSC and USPSA competition through their officially sanctioned shooting team.
Transit Security personnel often work in conjunction with deputies of the Los Angeles County Sheriff's Department's Transit Services Bureau, which has been the exclusive contract provider of dedicated law enforcement services for Metro since 2003.
