What does a firewall protect against?
an antivirus if I have a firewall? While a firewall can provide some level of protection against unauthorized access and certain types of threats, it is not a substitute for antivirus software. Antivirus software is designed to detect, prevent, and remove malicious software, including viruses, malware, and spyware. It scans files, emails, and websites for known threats and can also detect and block suspicious behavior. A firewall, on the other hand, primarily works at the network level, monitoring and controlling network traffic to prevent unauthorized access. It cannot detect or remove malware that may already be present on a system. Therefore, it is recommended to have both a firewall and antivirus software installed on your computer to provide comprehensive protection against a wide range of threats.
Here are some key points about firewalls:
1. A firewall is a security device or software that acts as a barrier between a private internal network and the public Internet.
2. The main purpose of a firewall is to allow non-threatening traffic in and keep dangerous traffic out.
3. Firewalls can prevent unauthorized access to your network and alert you to intrusion attempts.
4. Firewalls can block network traffic based on IP protocols, IP addresses, and port numbers.
5. They can also block malicious software and worms from infecting your computer.
6. Firewalls are not anti-malware tools and cannot detect or remove different kinds of malware.
7. Traditional antivirus software scans files and emails for threats but cannot prevent them from entering the network.
8. A firewall can be a hardware device or software that runs on a server or other device.
9. There are different types of firewalls, including packet-filtering firewalls, application-level gateways, and next-generation firewalls.
10. It is recommended to have both a firewall and antivirus software installed on your computer for comprehensive protection against threats.
Here are some frequently asked questions about firewalls:
1. Does a firewall protect against hackers?
Firewalls can help secure your computers from hackers by preventing unauthorized access to your network and alerting you to intrusion attempts.
2. What is the purpose of a firewall?
The main purpose of a firewall is to create a barrier between a private internal network and the public Internet, allowing non-threatening traffic and keeping dangerous traffic out.
3. Does a firewall protect IP?
A packet-filtering firewall can block network traffic based on IP protocols, IP addresses, and port numbers, offering a basic form of protection for smaller networks.
4. Does a firewall protect against viruses?
Firewalls can not only block unwanted traffic but also help block malicious software and worms from infecting a computer, providing protection against viruses.
5. Can a firewall detect malware?
While a firewall is not an anti-malware tool, it can prevent unauthorized parties from accessing your computer and dropping malware on your system.
6. Do you need a firewall if you have an antivirus?
While antivirus software scans files and emails for threats, it cannot prevent threats from entering the network. A firewall is a preventative measure that secures your network perimeter against viruses, trojans, and data theft.
7. What are the 3 main functions of a firewall?
The main functions of a firewall are to control network traffic, prevent unwanted incoming traffic, and validate access by assessing network traffic for threats.
8. What are 3 uses of a firewall?
Firewalls monitor and filter all network traffic, including outgoing traffic, application-layer traffic, online transactions, communications, and connectivity.
9. Can a firewall hide your IP address?
A NAT firewall can hide your private IP address, but not your public IP address. Devices connected to a NAT-enabled router share a public IP address, and the firewall prevents communication not initiated from a private IP address.
10. What are the 3 types of firewalls?
The three types of firewalls are hardware-based firewalls, software-based firewalls, and cloud/hosted firewalls.
Remember, having both a firewall and antivirus software is crucial to ensure comprehensive protection against various threats.

Can firewall detect malware
A firewall isn't an anti-malware tool — a basic firewall can't remediate or hunt different kinds of malware. However, a firewall can prevent unauthorized parties that intend to drop malware on your system from accessing your computer.
Do you need a firewall if you have an antivirus
Traditional antivirus will scan files and emails once the threat is already inside your network. It cannot prevent threats from entering the network. A firewall is a preventative measure that secures your network perimeter against viruses, trojans and data theft, and prevents these threats from entering your network.

A hardware firewall acts as a gatekeeper and antivirus solution for your server. It sits directly behind the router and can be configured to analyze incoming traffic, filtering out specific threats as they come across the device.
Does a router go behind the firewall
It's more likely that you'll need a router between your firewall and the Internet. In this location, a router can screen out an Internet stream's obvious "junk traffic" before it reaches the firewall. You can use the router to apply broad firewall rules across the enterprise.
