Access controls are security features that are usually considered the first line of defense in asset protection. They are used to dictate how subjects access objects, and their main goal is to protect the objects from unauthorized access. These controls can be administrative, physical, or technical in nature and should be applied in a layered approach, ensuring that an intruder would have to compromise more than one countermeasure to access critical assets. Explain each of these controls of administrative, physical, and technical with examples of real-world applications.
