Last time we compared the effectiveness and the practical applications of the hardware firewall and the software firewall. This time, we’re going to analyze the advantages and disadvantages of antivirus applications and firewall.
We’ve already covered the main aspects of a firewall, but let’s try to look at it put side by side with an antivirus.
The mail goal of a firewall is to handle data traffic security. It makes sure that no malicious data enters your computer and that no sensitive information leaves your computer without your permission. It acts as a prevention system, meant to intercept and attack before it can do any damage. If anything, you can compare it to border patrol, a security team that checks every package going both in and out. Continue reading →
The most obvious answer is, of course, to use both, since they don’t exclude one another and they CAN work together. But using both at the same time might not be necessary. To understand what configuration better fits which scenario, let’s first take a look at both firewall types and see their strong and weak points.
This is the firewall that is present inside a physical device, and is the one typically found inside broadband routers. This firewall makes use of packet filtering, a process that looks at a packet’s header to collect information about it, like its source and its destination. It then compares this information with its in-build database (or with a user designated rule set) to determine whether the incoming internet traffic contains any threats. Continue reading →
