Answer 1

A.

B.

C.

Step-by-step explanation:

A host-based firewall is a program that protects a single Internet-connected computer from intruders. It could do the following:

- Help prevent a system from being fingerprinted by port scans

- Restrict a computer from receiving network traffic.

- Stops attackers when they are outside of the company's internal network

Answer 2

Option b, c, d are true.

The correct statements are as follows:

b. Can restrict a computer from receiving network traffic

c. Stops attackers when they are outside of the company's internal network

d. Stop a process or application from launching

Step-by-step explanation:

Firewall can be defined as a wall or checkpoint that checks each entity before it accesses to go inside or outside a network.

A firewall:

• makes sure that the data inside a private network is safe by building a wall around it.
• restricts the malicious data to go inside the network.
• always ask about launching an application which is blocked by it due to suspicious activity.

A firewall can not:

• prevent a system from being fingerprinted by port scans.
• Disable an account.
