– Stops Virus Attacks: A firewall can prevent virus attacks from shutting down your digital operations.
8. How does a firewall protect a network?
A firewall is a security device — computer hardware or software — that helps protect your network by filtering traffic and blocking outsiders from gaining unauthorized access to the private data on your computer.
9. What are the strengths and weaknesses of a firewall?
Strengths: Firewalls can prevent unauthorized access and protect against external threats.
Weaknesses: Firewalls cannot stop users from accessing malicious websites, transfer of virus-infected files, prevent misuse of passwords, or protect if security rules are misconfigured.
10. What are the 3 main functions of a firewall?
The primary functions of a firewall are to secure the network and information by controlling network traffic, preventing unwanted incoming network traffic, and validating access by assessing network traffic for malicious things such as hackers and malware.
11. What are the pros and cons of firewalls?
Pros: Firewalls can protect systems from basic types of trojans and provide essential network security.
Cons: Firewalls may have limitations in protecting against other types of threats, misuse of passwords, and misconfigured security rules.
12. How do firewalls enhance network security?
By filtering network traffic, firewalls help prevent unauthorized access and block potential threats from entering the network, ensuring overall network security.
13. How often should firewalls be updated?
Firewalls should be regularly updated with the latest security patches and firmware to ensure they stay equipped to protect against emerging threats.
14. Can firewalls prevent all types of attacks?
While firewalls are an essential security measure, they cannot prevent all types of attacks. Other layers of security, such as intrusion detection systems and antivirus software, are also necessary for comprehensive protection.
15. Are firewalls necessary for both home and business networks?
Yes, firewalls are crucial for both home and business networks. They protect sensitive data, prevent unauthorized access, and provide a secure environment for online activities.

What are the 3 main functions of a firewall
Functions of Firewall
Therefore, a firewall's primary function is to secure our network and information by controlling network traffic, preventing unwanted incoming network traffic, and validating access by assessing network traffic for malicious things such as hackers and malware.
What are firewall pros and cons
Firewalls can protect systems from the basic types of trojans, but they are not capable of protecting systems from other types of malware, and possibly this malware can enter the system in the form of trusted data. To handle this type of problem, anti-malware software needs to be installed along with malware.
What are key facts about firewalls
It is used to protect internal networks and private or sensitive data. A firewall also logs information about network traffic, which can help an administrator understand and prevent attacks. Typically, a firewall allows no direct connection between the internal network and the Internet.
