Your second line of defense is good antivirus software.Sometimes ransomware tricks you into encrypting your own hard drive by clicking on a file attachment that you thought was benign.Or maybe your company's accounts receivable files or your hospital's patient records. The particular ransomware making headlines is called Wanna Cry, and it's infected some pretty serious organizations. Your first line of defense is to diligently install every security update as soon as it becomes available, and to migrate to systems that vendors still support.Microsoft issued a security patch that protects against Wanna Cry months before the ransomware started infecting systems; it only works against computers that haven't been patched.Your third line of defense is to diligently back up your files. If your irreplaceable family photos are in a backup drive in your house, then the ransomware has that much less hold on you.There are systems that do this automatically for your hard drive. If your e-mail and documents are in the cloud, then you can just reinstall the operating system and bypass the ransomware entirely.Computers run our traffic lights and our power grids. The Mirai botnet exploited a vulnerability in internet-enabled devices like DVRs and webcams to launch a denial-of-service attack against a critical internet name server; next time it could just as easily disable the devices and demand payment to turn them back on.
There are computers in your cars and in the airplanes you travel on.
Antivirus software can often catch your mistake and prevent the malicious software from running.
This isn't perfect, of course, but it's an important part of any defense.
I know storing data in the cloud has its own privacy risks, but they may be less than the risks of losing everything to ransomware.
That takes care of your computers and smartphones, but what about everything else?
