On finding any suspicious traffic, the firewalls block them right there.

2-way firewalls even monitor outgoing and incoming traffic, so there occurs no information leak or theft. When you have installed a firewall, your network remains safe in a protected dome. Protecting your inside network infrastructure by blocking suspicious outgoing connections.Defense against outside threats by blocking unauthorized connection requests, which may be a potential hacker.A firewall can accept, deny, or drop traffic based on a set of security rules. It is installed between your internal network and the rest of the internet or external network to filter incoming and outgoing data or traffic. If you use a firewall, it monitors your network traffic while identifying and blocking unwanted data packets. This is how most worms, Trojan horses, or bad bots travel. These threats detect a computer with unpatched vulnerabilities or weak security settings, and when they do, they insert themselves into those systems.Ĭomputer and mobile devices get compromised, and cyber criminals manage to steal data, pose financial threats, or whatever they want. Threats move from one computer to another, and it happens while the users have no idea about it. Although it can detect new and known threats to protect your files, you can add a second layer of technology to complete the picture.Īnd the layer we are talking about is a firewall.Īn efficient firewall helps keep your data safe by restricting external threats to access your system and trouble you. Therefore, internet users must stay one step ahead of them to protect their data and privacy.

Thanks to technology, we have some methods and tools to mitigate such issues.īut here’s the catch, technology is evolving not only on our side but also for cyber crooks who continue deploying more advanced threats like malware, ransomware, etc. As online attacks are (in)famously common these days, having rock-solid security has become essential for Internet users.
