What are the two functions of the firewall in the network?

Firewalls primarily serve two crucial functions within a network: preventing unauthorized access and protecting against malicious content.

Core Firewall Functions

A firewall acts as a security guard for your network, controlling what can enter and leave. It's essential for safeguarding your systems and data.

Function	Description
Prevent Unauthorized Access	Firewalls prevent unwanted intrusions by blocking unauthorized access to your network from outside sources (e.g., hackers) and even from within your network by insiders. This helps to ensure that private data and vulnerable systems remain secure. Controls network traffic based on pre-defined rules. Blocks suspicious connections and access attempts. Protects against internal and external threats.
Prevent Malicious Content	Firewalls filter incoming data and block harmful content, preventing malware and other unwanted material from entering your environment. This protects devices and data within your network from threats like viruses, spyware, and ransomware. Scans network traffic for harmful software. Prevents the download of malicious files and applications. Reduces the risk of infections and data breaches.

In essence, a firewall acts as the first line of defense in your network's security infrastructure.
