A Security Assessment Report (SAR) is a document that summarizes the findings and recommendations of a security assessment. A SAR should include the following sections: an executive summary, a scope and methodology, a threat and risk analysis, a vulnerability analysis, a security control assessment, and remediation recommendations. Remediation recommendations are the best practices that the SAR should include, as they provide the actions that need to be taken to address the identified security gaps and risks. Data classification policy, software and hardware inventory, and names of participants are not essential sections of a SAR, although they may be included as supporting information or appendices.

The retina, a thin nerve (1/50th of an inch) on the back of the eye, is the part of the eye which senses light and transmits impulses through the optic nerve to the brain - the equivalent of film in a camera. Blood vessels used for biometric identification are located along the neural retina, the outermost of retina's four cell layers.

Explanation:
Training is an administrative control, not a physical control.
Controls are put into place to reduce the risk an organization faces, and they come in three main flavors:
administrative, technical, and physical. Administrative controls are commonly referred to as "soft controls" because they are more management-oriented. Examples of administrative controls are security documentation, risk management, personnel security, and training. Technical controls (also called logical controls) are software or hardware components, as in firewalls, IDS, encryption, identification and authentication mechanisms. And physical controls are items put into place to protect facility, personnel, and resources. Examples of physical controls are security guards, locks, fencing, and lighting.
Incorrect Answers:
A: Lighting is an example of a physical control. Therefore, this answer is incorrect.
B: Fences are an example of a physical control. Therefore, this answer is incorrect.
D: Facility construction materials are an example of a physical control. Therefore, this answer is incorrect.
