You have undoubtedly learned that a large-scale computer attack was launched last week. Thousands of computers around the world have been affected by a ransomware ( Ransomware) particularly effective, notably WannaCry. It was specifically data security that was concerned. In fact, the software locks access to your files and requires you to pay substantial sums of money to unlock them.
We alerted you a few days ago to the reality of these data security breaches in this article. The phenomenon is indeed taking on increasingly significant proportions. For example, the graph below illustrates the increase in malicious spam.
Therefore, for data security, we always recall an obvious principle of good management. Do you think your money is safer in the bank? Well, your data is also safer in a professional cloud than under your mattress!
Let's detail the propagation of this ransomware and establish the tools that provide the best guarantees of protection.
The spread of WannaCry ransomware
Friday May 12, millions of computers running Windows XP found themselves contaminated by this ransomware. You will find here the propagation map produced by the New York Times.
Once introduced into your system, by email or network, the malware spreads to your files and blocks them. Le Monde offers here a summary of the attack and its consequences.
The victims are companies or individuals equipped with Windows XP who have not downloaded the most recent updates. If they had done them, they would have avoided contamination. Likewise, if they had Macs or PCs not equipped with XP, they would have avoided this attack as well. You can read about this this article in Free Belgium.
How to ensure the security of firm data
The propagation of viruses is based on a necessary condition: having an operating system. In this case it was Windows XP, but a large number of ransomwares work under other versions of Windows.
By using software like Jarvis Legal, which is entirely cloud-based, the security of the firm's data is guaranteed. Indeed, your data is stored on extremely protected servers and very little sensitive to this type of threat. Conversely, software requiring the installation of an .exe file or the storage of your data on your server (even if hosted) poses a risk to the firm.
To conclude:
- if you have your data locally or on your own hosted server, use the best antiviral solutions, rely on an experienced system administrator, and back up your data frequently. However, this risks increasing your IT budget!
- if you have your data in the cloud, check the commitments made by your supplier as well as their insurance. As far as we are concerned, the conditions are provided on our quotes :o)
