What is the difference between Intrusion Detection System $($IDS$)$ and Firewall?

Firewalls focus on preventing unauthorized access to the network, while Intrusion Detection Systems $($IDS$)$ focus on identifying and responding to potential security breaches and malicious activities within the network.

Firewalls analyze network packets to determine whether to allow or block traffic based on predefined rules, while Intrusion Detection Systems $($IDS$)$ detect and alert on suspicious activity within the network.

Intrusion Detection Systems $($IDS$)$ actively block unauthorized access attempts, while firewalls passively monitor network traffic.

Intrusion Detection Systems $($IDS$)$ are typically deployed at network boundaries, while firewalls should be deployed at each workstations in the internal network to monitor traffic between different zones.
