to prevent unauthorized persons from gaining access to a private network
No - a firewall is a piece of hardware and/or software to prevent unauthorised access to your computer over the internet.
Firewalls cannot contain viruses. They can only try to prevent or block them from getting into your computer.
Firewalls are used to prevent users. The users will not be able to see the blocked content then.
Firewalls are a form of security. They prevent other users and PCs from accessing your PC. I say. Turn it on and leave it on.
i have just removed w32.mota.b@mm using pest patrol. firewalls prevent virusses. you need a anti-virus. probably most of them are able to.
The four basic types of firewalls are packet-filtering firewalls, stateful inspection firewalls, proxy firewalls, and next-generation firewalls (NGFW). Packet-filtering firewalls inspect packets and allow or block them based on predefined rules. Stateful inspection firewalls track the state of active connections and make decisions based on the context of the traffic. Proxy firewalls act as intermediaries between users and the internet, while next-generation firewalls combine traditional firewall features with advanced security functions, such as intrusion prevention and deep packet inspection.

There are many companies online that sells firewalls to other companies. Two companies that one can go to that sells firewalls is called Barracuda and Cisco Systems.
The three main types of firewalls are packet-filtering firewalls, stateful inspection firewalls, and proxy firewalls. Packet-filtering firewalls analyze data packets and allow or block them based on predefined rules, focusing on IP addresses, ports, and protocols. Stateful inspection firewalls maintain a record of active connections and make decisions based on the state of these connections, providing more security than simple packet filtering. Proxy firewalls act as intermediaries between users and the internet, forwarding requests and responses while hiding the user's IP address and providing additional security features.
Firewalls do not protect from viruses. Firewalls can help reduce the chances of being hacked, though an expert hacker might still find a way in. But it will be harder and take more time.
A firewall can help prevent DDoS attacks by monitoring incoming traffic and filtering out malicious requests that exceed predefined thresholds. By implementing rules that block or limit excessive traffic from specific IP addresses or geographic regions, firewalls can reduce the impact of an attack. Additionally, advanced firewalls can use anomaly detection to identify and mitigate unusual traffic patterns indicative of a DDoS attack. However, while firewalls are a crucial line of defense, they may not completely eliminate the risk, necessitating a layered security approach.
