A firewall is one key component of computer security protection. As a key component in security software, firewalls protect your devices specifically by doing the following:. You connect to the web through networks, and networks can be accessed by others.
Someone who gains access to your computer through the internet can access your valuable information. Remote access to your computer can mean cybercriminals can access sensitive files or your saved log-in information. In security software, firewalls help protect against unauthorized access and data going in and out of your computer.

Specific threats that firewalls protect against include:. Once the Smart Firewall lets permitted traffic in, IPS carefully examines the contents of the traffic that comes through. In Norton device security software, another part of the software called the Intrusion Prevention System, or IPS, uses machine learning to look at millions of data points of what good traffic and bad traffic does, and the IPS then informs the firewall with its learnings.
This is particularly important for security in the case of new attack methods that cyber criminals try to use to infiltrate computers or home networks, or to protect against attacks that use old malicious code re-purposed in different ways to bypass security filters. IPS and a firewall are part of the layer of security software that helps protect your computer at the network level, and they work in conjunction with other parts of security software like antivirus that protect in additional ways.
