This term is usually synomymous to the term "Countermeasure", "Safeguard" or "Measure". Controls are usually considered as means to mitigate risk.

UNISDR
UNISDR does not use the term "control". It defines two types of "measures": Structural and Non-structural measures [1].
- Structural measures: Any physical construction to reduce or avoid possible impacts of hazards, or application of engineering techniques to achieve hazard- resistance and resilience in structures or systems. Common structural measures for disaster risk reduction include dams, flood levies, ocean wave barriers, earthquake-resistant construction, and evacuation shelters.
- Non-structural measures: Any measure not involving physical construction that uses knowledge, practice or agreement to reduce risks and impacts, in particular through policies and laws, public awareness raising, training and education. Common non-structural measures include building codes, land use planning laws and their enforcement, research and assessment, information resources, and public awareness programmes.
Note that in civil and structural engineering, the term “structural” is used in a more restricted sense to mean just the load-bearing structure, with other parts such as wall cladding and interior fittings being termed non-structural.

Measure that is modifying risk [2] The standard notes that:
- Controls include any process, policy, device, practice, or other actions which modify risk.
- Controls may not always exert the intended or assumed modifying effect.
Each control is usually associated to a control objective, which is a statement describing what is to be achieved as a result of implementing the control.
