Frequently Asked Questions About Firewalls
Enlisted below are the most commonly asked questions about Firewalls.
How do Firewalls Protect from Hackers?
Answer: Firewalls protect from hackers by blocking their access to your PC via Wi-Fi and the internet.
To access your PC and steal sensitive data such as browsing history, bank details, passwords, and other information, hackers use keylogging software and Trojan viruses to record your sessions and monitor your keystrokes. Keystrokes mean what you enter onto your PC or another device.
Hackers can run illicit activities using your computer even without your knowledge. The good news is that firewalls can help to stop them.
Can a Firewall be Hacked?
Answer: It is a rarity that a firewall can be hacked. Although a firewall is meant to protect your computer from hackers, the security of your system can be compromised if you misconfigure or inappropriately maintain a firewall. Cybercriminals can easily hack a firewall if it is not correctly tuned.
Also, regardless of how strong your firewall protection is, hackers can bypass the firewall if there are vulnerabilities in the systems and applications that the firewall protects. For instance, attackers can utilize several vulnerabilities in Windows to enter into your computer.
All they need to do is convince you to visit an infected web page. This makes it essential to have antivirus and anti-malware software installed alongside the firewall on your PC or systems.
Also, ensure all applications and operating systems are patched to the latest version. If you do this, there’s a little chance of a hacker gaining access to your system.
