Question

1. What is the difference between infrastructure security and premises security?
2. List and describe three categories of physical threats caused by humans.
3. What are the two requirements for physical security?

Answer 1

Difference between infrastructure security and premises security:

• Infrastructure security protects the infrastructure of an environment. But, Premises security protects physical premises.
• Infrastructure security is comparatively cheaper than premises security.
• Infrastructure security needs no continuous monitoring. But premises security needs continuous monitoring.

3 categories of physical threads caused by human:

1.Natural events:

• Like flood, earthquake, etc
• Very hard to plan.
• Because it is unpredictable.
• Loss of resources and damage to property.
• In order to mitigate this, we should always stay alert by using equipment such as sensors, alarms, etc.

2.The intentional act of destruction:

• Like theft, vandalism, etc.
• Includes activities like the damage or destruction of the public or private property.
• We can predict the way of attack so some degree of accuracy.
• By using proper measures, we can reduce these kinds of threats.

3.Unintentionally destructive acts:

• Like bad plumbing, spilled drinks, etc
• Not done intentionally.
• That is without malicious intent.
• Careless behavior may lead to this.
• By doing everything carefully, we can reduce these kinds of threats.

Two requirements of physical security:

1.Understanding what you need to protect.

• First of all, we need to know or understand what we actually need to protect.
• Understand about the facilities also and know about what kind of facilities are available, which facilities are to be used and who need to use it.

2.Accessing physical security risks.

• We need to access the risk of each site that we use separately.
• And also we need to include them in the risk registers.
