Do You have an Active Antivirus Software, Firewall or Internet security? Check If Its Working

This post gives you a complete insight on an active antivirus software. These days cybercrimes just keep rising very fast leaving  many digital device  users open to various forms of attack from viruses, malware and so on. These attacks are very bad because they can make the use of our devices very frustrating .When you dont have active antivirus software these viruses get access to our systems via an unsecure internet connection or downloads.Hence, this post is aimed at tackling this security issue, just sit back and enjoy it.

                            active antivirus software
At first, it may appear that the simplest way to see if you have an active antivirus software would be to gather up thousands of  crazy viruses, and to set them lose on a network. Then, you can go back and measure the percentage that were blocked in order to determine the effectiveness of your active antivirus software. However, these results are not foolproof since it might fail to expose critical flaws in your security.
Before attempting this kind of test, you must first check to make sure that your network security is actually working. A better way of doing this would be to test just one simple virus, and alter it in various ways to detect specific vulnerabilities.
You can get a benign test virus here. This file shouldn’t hurt your system, but it SHOULD trigger your antivirus.
Now that you have a virus for testing, you’ll also want to set up an external Linux web server, FTP server and email server to deliver the file. In order to truly test the capabilities of your security, you’ll also want to switch between different ports.
For example, you may want to set up web servers on port 80 and 242. And you may want to set up the POP server on port 110 and another on port 23 – which is normally used for Telnet.
Then, try and push the file into your network using different means, and hiding the file in different ways.
  • Try sending it as a simple email attachment.
  • Try compressing the virus into a ZIP file
  • Try making a ZIP file using a ZIP file containing the virus
  • Try to single and double ZIP the virus, and password-protecting it
  • Try unconventional compression formats like RAR or GZIP
  • Try changing the name of the file
  • Try changing the file extension so that it appears to be another type of document (.PDF, .JPG, .PPT)
  • Embed them into a document such as Word or Excel.
If you use your imagination, you could probably come up with a hundred variations. Once you’ve done this, you’re ready to start testing your active antivirus software.
Try emailing the file into your network, and also try sending it out from within your network.  Additionally, you’ll want to try sending it internally from one machine to another.
Post all of these files up on your web servers and FTP servers, and try downloading all of the files.
Set up an online message board on your web server and see if the virus files can be uploaded to the forum as an attachment. Also, try doing the same on your private, intranet if you have one in place.
Try downloading the files from other sources, such as Gmail or any other hosted applications that could potentially be used to distribute viruses.
As you grow your options, you’ll develop a wide matrix of potential vulnerabilities. Keep a spreadsheet of your results in order to spot patterns.
Once you’ve broadly secured your network against a single virus, exhaustively tested in every possible way, you’ll have much more to gain from more advanced testing.
 N.B- Always test offline, and never compromise a live, critical system.
