What is subnetting and how does it enhance network security?

Subnetting is the process of dividing a network into smaller, manageable sub-networks. It enhances security by isolating segments, limiting broadcast traffic, and controlling access.

Can you explain how subnetting helps in controlling access?

Certainly! By creating subnets, you can implement access control lists (ACLs) to restrict traffic between different segments, ensuring that only authorized users can access sensitive areas.

What are the security risks of not using subnetting?

Without subnetting, a single breach can compromise the entire network. It also leads to increased broadcast traffic, making it easier for attackers to exploit vulnerabilities.

How do I determine the right subnet size for my organization?

To determine the right subnet size, consider the number of devices you need to accommodate, future growth, and the level of security required for different segments.
