Firewall or Antivirus – Who should you trust?

Last time we compared the effectiveness and the practical applications of the hardware firewall border securityfirewall 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

What Firewall Should You Use – Hardware or Software?

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.

Hardware firewall

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

Problem-Solving Is the Problem

The ideal scenario of preventing problems altogether needs to be reached

In a business, just as anywhere else, problems will arise. It’s human nature to forget, to be careless and to be fatigued. What’s important is to not accept it as a matter of fact. Progress, in itself, implies overcoming one’s limitations – being more that you were a minute ago. If humans would have accepted the fact that only birds can soar through the sky and only fish can scour the depths of the ocean, we never would have even invented the wheel. So instead of accepting errors, we need to be able to look past them.

No matter how quickly it’s applied, a solution implies that an error has occurred. So if finding a solution IS the problem, how do we solve this? We invest more time and resources in to a prevention system, and less in to an “it’s-broken-quick-we-need-to-stich-this-up” system. Continue reading

The Importance of a Structured IT Network Inside a Company

A company is a very intricate system. It’s complicated, it’s elaborated and it’s vast. There are dozens of departments, each of them acting as a pillar that holds the company above sea-level, well afloat. And for every person in the company there’s a computer that enables them to do the work that is required of them.

The human half of the system, can, to a certain degree manage itself. If things start going downhill, a human’s self-preservation instinct kicks in and makes sure that any threats are eliminated or avoided entirely. (We take a vacation; we drink ourselves silly until our mind is a blank) Continue reading
