Software Security

  1. The Do test: What does the program do? You should be able to read a clear description of what the program does. This description could be on the web site where you can download it or on the CD-ROM you use to install it. You need to realize that that if the program was written with malicious intent, the author/intruder isn’t going to tell you that the program will harm your system. Consider the source and consider whether you can trust that information.
  2. The Changes test: What files are installed and what other changes are made on your system when you install and run the program?
  3. The Author test: Who is the author? Make sure your using licensed and authenticated software.
  4. The Learn test: Has anybody else used this program, and what can you learn from him or her? Try some Internet searches using your web browser. Somebody has probably used this program before you, so learn what you can before you install it.
  5. The File Size test: look at the file size of the files that you want to download. For example, you want to download freeware software from a web site and you know that the software file size should be around 12 or 13 MB. But on that web site, it says 234 KB. You need to be very careful with this as it might be a virus or Trojan because the size is just not right.
  6. Use a Firewall: Use a firewall before downloading any software. If the software you've downloaded is trying to send privacy information to the hackers, it will not be able to do so because the firewall will block its outgoing traffic.
