Top 5 Reasons on why you need Firewall
What is a Firewall?
A firewall is a network security device that monitors incoming and outgoing network traffic and allows or denies traffic based on a set of security rules. Its purpose is to create a barrier between trusted and untrusted networks, such as the internet, in order to block malicious traffic like viruses and hackers.
Firewalls help to prevent unauthorized access
Firewalls help prevent unauthorized remote access by filtering traffic and blocking outsiders from gaining access to your network. It can also block users from accessing specific websites and programs from unauthorized internet access.
A firewall can protect old PCs in the short term
There are still people using Windows XP and Windows 7 even though there are newer versions and some of them are using them without any firewall. This makes them vulnerable and easy targets for hackers. For those using Windows 7, install a proper firewall and get yourself protected.
