✅What is the main purpose of a firewall in network security?
A firewall acts as a security gatekeeper between your private network and the public internet. It examines incoming and outgoing network traffic based on predefined security rules.

✅How do different types of firewalls differ from each other?
Firewalls vary primarily in their approach to inspecting data:
➡️Packet-filtering firewalls simply check data packets against known rules.
➡️Stateful inspection firewalls track the state of network connections and inspect both incoming and outgoing packets.
➡️Proxy firewalls filter network traffic at the application level, offering more detailed scrutiny.
➡️Next-generation firewalls (NGFW) combine the above features with additional capabilities like intrusion prevention, deep packet inspection, and application awareness for comprehensive security.

✅Can firewalls protect against all types of cyber threats?
Firewalls are crucial for network security but they are not foolproof against all cyber threats. They excel at blocking unauthorized access and managing network traffic. However, they work best alongside other security measures like antivirus software, intrusion detection systems, and secure web gateways
