What is antivirus software?

Antiviruses are software programs that prevent certain pieces of malware from infecting users’ endpoint devices. In general, antivirus solutions  follow a signature-based approarch. That is, their objective is to identify certain patterns, behaviors or unauthorized alterations in the files or devices.

How does antivirus work?

The pattern or process is always the same. Consists of constantly comparing software databases or malicious programs with system files. When there is a match, a certain event is triggered. It can either be to repair the file, quarantine it, delete it or analyze its behavour, among others

Are antiviruses solving current problems?

In recent times we are seeing how different factors are coming together to form the “perfect storm”:

  • Malware is increasingly complex. Some variants of malware are even able to transform themselves.
  • After so many years, hackers know well how to bypass traditional security perimeters. As a result, they have learned how to design malware pieces to evade antovirus protection systems.
  • Every day, hundreds of thousands of new malicious programs are registered.
  • Changing and complez environment: mobile users, remote workers, applications in the cloud, compliance obligations, etc.

All this is leading to an accelerated obsolescence of traditional antivirus. Hackers are innovating faster than traditional defenses can be maintained, and it is increasingly difficult to find the needle in the hay stack.

Also, there is something antivirus solutions will never be prepared for: protect companies against naive employees. A simple click on a malicious attachment or URL is enough to compromise the entire network.

A study conducted by Ponemon Institute reveals that 69% of companies recognize that antivirus systems do not provide adequate protection for their systems.

How can we solve the problem?

With traditional solutions, we either stop or block threats, but the problem is always the same: it is too late. They have already entered into our system and the damage is already done.

Therefore, the solution must not be reactive (react to something that has already happened) but proactive (prevent something from happening). That is, stop investing time and resources in mitigating the damage done and dedicate them to neutralize it.

In every cyberattack there are two elements: the hacker and the victim. Trying to control the hacker is a mistake. In fact, it is something that is becoming increasingly challenging to the point that most of the time it is impossible.

However, there is something we can do: eliminate the attack surface. Only then can we be sure that no piece of malware can reach its target. Regardless of the changing environment or the complexity of attacks, the organization will be completely protected.

All this is possible with RITech, the web isolation technology that creates air gaps or air spaces between the Internet and the corporate network. Since there is no direct communication between users and the Internet, no web-based malware can ever reach the corporate systems.
