People often become confused over what type of online protection they need to remain safe from malicious web-users. This means that anti-virus, anti-spam, and firewall programs are often viewed as interchangeable. However, you need all three in order to remain safe.

Anti-Virus

An anti-virus program protects you against malware, particularly trojans. Trojans can cause incredible harm to your computer since they are often very difficult to detect. Just like a real virus, they often lie dormant for some time before activating. Once they do, they can take control of your system in a number of ways. This might involve something relatively noticeable, such as placing a harmful virus on your laptop, but more subtle trojans exist which begin attempting to steal your details by recording keystrokes. This method can be used to seize personal information such as banking details and passwords.

Anti-Spam

Spam might only seem like a minor annoyance, and has indeed been shown to lower productivity in the working environment, but the real costs can be far greater. Hackers soon realised that emails represent a weak spot through which to send malicious programs, so anti-spam should be thought of as a crucial part of your IT safety system. Spam email can contain viruses, and these often access your contacts to begin sending junk from your own account. From business accounts, this can be extremely embarrassing, and is a sure-fire way to appear unprofessional

Without a proper anti-spam program, you also leave yourself open to phishing attacks – the use of official looking forms to trick people into supplying sensitive information.

Firewall

Essentially, a firewall is your first line of defence against malicious attacks. If anti-virus represents a kind of cure, then you can think of your firewall as representing a kind of vaccination.

Your firewall will control both incoming and outgoing traffic based on security settings which you can monitor and customize yourself. However, it’s worth remembering that firewalls typically need to be updated regularly in order to remain effective. Hackers are constantly attempting to find ways through, so IT professionals regularly need to make alterations to ensure that security remains strong. If an icon appears telling you to update your firewall, don’t click it away.

 

Safeguarding your IT system is a necessity, so make sure you have these three types of protection installed.
