Three types of physical security hardware are intrusion detection, surveillance systems, and access control systems. All three hardware systems a highly effective and prevent the intrusion of unwanted persons. Each system serves a different purpose that ensures the physical protection of data.

There are five types of intrusion detection systems, a few are Network-based intrusion detection systems, Host-based intrusion detection system, and Protocol-based. (What Is an Intrusion Detection System?, n.d.) Network based intrusion detection monitors all traffic flowing from and to devices on the protected network. This is valuable today due to the advanced malware that hackers use.

In today’s society it is imperative for surveillance systems. Surveillance systems use to be used on more of a commercial basis but since the introduction of affordable home surveillance like the Ring camera surveillance systems have become accessible to majority of consumers, allowing to monitor camera activities from the phone or computer.

Access control systems are physical hardware that has become indispensable. Access control systems set specific restrictions for access to areas of company property. Three types of access control systems are role-based access control, attribute access control and discretionary access control. (Locksmiths, 2023) All three systems are used to protect sensitive areas by only allowing users with those credentials to access the area.
