Spain is the seventh country in the world suffered from ransomware attacks. This type of malware infects computers and encrypt your files so you can’t access them. Until pay a ransom. Extortion, which brings millions of euros in losses, profits to scammers and involves loss of documents important, and that companies and individuals cannot continue their daily lives. If you do not take the initiative and apply the policy Backups according to the 3-2-1-1-0 rule.
In a previous article, I talked about the 3-2-1 rule. Thanks to her, Backups whatever you do, at home or in the office, will be safer and you will be able to use them if something happens to your computer. Due to computer problems or ransomware infection. But this rule can be improved. And security experts are already promoting an extended version known as the 3-2-1-1-0 rule. It starts with the same basics but improves upon it to defeat ransomware before it even infects your devices.
And it is that if it is already difficult to make backup copies, if in addition you do not save them correctly, then they will be of little use to you when you need them. restore them and thus recover your files and important documents. It is the access to backups that is the fastest solution if you ransomware victim.
Remember the 3-2-1 rule
Making a backup is not easy. You must decide what is worth being in this backup. Where will we store it? With what periodicity we’ll make it How many copies do we need? In part, this preliminary preparation is much more important than the copy itself. And there are many applications for make automatic backups. Hence the recommendations with the 3-2-1 rule or its extended version, the 3-2-1-1-0 rule.
When I discussed the 3-2-1 rule earlier, I explained that each number refers to a backup step. Thanks to this easy-to-remember rule, backups make more sense as they are easier to restore and are designed to deal with all sorts of disasters and unforeseen. It is better to spend some time and not need them than to regret later that you did not prepare them properly.
3 of the 3-2-1 rule refers to the creation three backups. The first copy and two additional ones. The more copies, the better. But three is enough. It would be possible to serve, but just as we can lose original filesYou can also lose your backup.
2 has to do with keeping backups in two different places. For example. If you keep your files and backup on the same device, if it gets lost, stolen, or stops working, you won’t be able to restore neither original nor copy. Solution? Place each backup in a different location than the original files you want to protect. And today it’s very easy select multiple fonts: optical discs, flash drives or USB drives, external drives, SD memory, online storage, dedicated servers, NAS devices…
Finally, the 1 of the 3-2-1 rule means storing the backup outside of the physical location where you have your files and one of the copies. The clearest example. You have files on your office computer and a backup in your desk drawer. What happens if someone hacks or if there is Fire? You will lose the original and the copy. But if you keep a second copy In your house or in the second office everything changes.
More secure copies with the 3-2-1-1-0 rule
Now that we have the 3-2-1 rule in mind, explain what is the improved version it does not take a lot of time. It basically adds two extra phases or elements to the equation. So in addition to 3 backups, 2 different locations, and 1 of them outside of the original, we can add two improvements.
The 3-2-1-1-0 rule adds two new elements. First, one of the backups is available offline. This is important because ransomware attacks originate from the Internet and consist of infecting any file that is visible from the network. Have at least one offline backup This will allow us to recover these important files and thus safely format computers affected by ransomware without fear of losing anything. Everything is in reserve.
The last digit of the 3-2-1-1-0 rule means zero backups unverified or erroneous. One detail we don’t take into account when creating backups is that the file copy may not be entirely reliable. That is, files may have been skipped, or some may have been copied incorrectly. causing: micro power outages, saturation or imperceptible stops in devices that send and receive data… The solution is included in the backup tools. After copying is complete check that it was done correctly and that there are no errors in it.
By applying the 3-2-1-1-0 rule to your home or office, if one day you encounter a ransomware infection, you won’t have to worry about paying a ransom or losing hours of work because you can’t access to your equipment. Disconnect them from the internet, format, reinstall everything, install patches and updates accordingly, check the absence of infection and finally restore the backups. Backing up according to the 3-2-1-1-0 rule takes time, but the process can be automated And it’s worth your time. At worst, there will come a day when these backups are needed. At best, you won’t have to deal with them.
