+Cybersecurity Forensics Lesson 1.2.3
+
+___
+### Physical Security Controls
+- Bollards
+- Access Control Vestibule
+- Fences and Signs
+- Video Surveillance
+- Security Guard
+- Access Badge
+- Lighting
+- Sensors
+
+### Bollards
+- Restricts access to a particular area
+- Channels people through a specific point but prohibits cars or trucks.
+- Other examples include moats, concrete barriers, and gravel pits.
+
+### Access Control Vestibule
+- Helps to enforce a “one scan, one entry guideline” for access to a restricted area.
+- Small space with two sets of interlocking doors installed in a way that the one set of doors must be closed before the other set can open.
+- Also known as sally port, air lock, or mantrap
+
+### Fences and Signs
+- A fence is a barrier, railing, or other upright structure that clearly defines the perimeter of the area.
+- Signs can deter some people, but for other malicious users, they can be a case of “x marks the spot”.
+
+### Video Surveillance
+- Closed Circuit Television (CCTV) is video surveillance you can use to see what is happening within your facility.
+- Ensure to use camera with the right properties including focal length, field depth, and lighting requirements.
+
+### Security Guard
+- Allow or disallow people through a security checkpoint.
+- Robot sentries
+- Receptionists
+- Two-person integrity
+
+### Access Badge
+- Logs movement through a central security system.
+- Correlates logs between the physical world and digital world
+
+### Lighting
+- Proper internal and external lighting are critical elements of physical security.
+- Dimly lit areas make it easier for intruders to easily execute illicit operations.
+
+### Sensors
+- Infrared
+	- Motion detection and night vision camera and can alert for possible movement within a given area.
+- Pressure
+	- Can detect pressure near a door or atmospheric pressure in a room.
+- Microwave
+	- Can automatically turn on lights in a room due to motion but also set off alarms from motion.
+- Ultrasonic
+	- Can be used for proximity and distance.
