How To Protect Your Security System Against Trojans?

Trojans are malicious, security-breaking programmes that come under the guise of something important/benign. In this way, a non-suspecting user installs or makes use of these programmes/files only to be attacked by the same; in ways that compromise data and security.

It gets the name from Trojan horse, the unsuspiciously sneaky war tactic that was used to disarm and defeat the unsuspecting enemy when at its weakest.

Types of Trojans one comes across:

1) Proxy: These allow the computer to be controlled by hackers.

2) Destructive: These type of Trojans destroy the core files of the computer.

3) Denial of Service (DoS): These type of Trojans gain access to the network bandwidth and cause the site to crash or malfunction.

4) Data sending: These Trojans gain information from your computer and send them across to the hacker.

How does a system get infected with Trojans?

1) Visiting already infected sites

2) Opening email attachments

3) Making use of non-suspecting freeware

4) Downloads that appear to be useful

How to protect your system against Trojans?

1) Firewalls are the most efficient ways to block the entry of Trojans and filter out the unnecessary spam stuff that is trying to make its way to your system.

2) Installing excellent anti-virus helps a lot too. The anti-virus must be kept updated all the time, with regular checks and screening to see if things are working alright or not.

3) It is essential to educate all about the idea of opening email, site links or attachments that are not from a verified or secure source. It is essential that one knows the difference between fake sites and legit ones. One cannot become the master of it overnight but a little vigilance can help protect your system from unnecessary damage.

4) In windows, there are certain extensions like “vbs”, “com”, “bat”, etc. that aren’t to be opened.

5) A server at the main level that segregates and separates the unwanted malware and virus scanner is what’ll get you through this.

Once a Trojan has installed itself in your system you can only pray that it doesn’t cause much damage and look for ways to secure your data and hence it is essential that you remain vigilant about it all the time so that you wouldn’t have to look for remedy options once the damage is done. Alertness is required.
