How To Protect Data From Ransomware
Ransomware is a form of malware that locks data and prevents users from accessing them. While this type of threat is not new, its rapid growth and ability to create chaos make it a serious concern. In addition to threatening businesses of all sizes, ransomware also causes significant revenue losses.
The best way to protect against ransomware is by using a robust backup system. This should be a priority for any organization with important data, as the loss of information can be devastating. Although data backups are not a foolproof protection against ransomware, it can provide peace of mind and limit the impact of an attack.
Another effective strategy for protecting against ransomware is to use multi-factor authentication. By using a unique password and additional authentication layers, such as iris scan or fingerprint, you can ensure that an attacker cannot access your information. However, this is only one part of a comprehensive security plan. You should also be aware of the most common ransomware tactics, such as phishing emails, and train employees to recognize these attacks.
Using a strong encryption solution is another great way to help protect against ransomware. A gold-standard data encryption solution can offer fine-grained access control and enforce policies, making it easier for organizations to protect against attacks like this. Also, these solutions often have application whitelisting capabilities, which helps ensure that critical applications can continue to operate smoothly after a hack.
Increasing your backup frequency can help minimize the impact of a ransomware attack. The number of backups you need to save depends on the size and importance of your data. For instance, if you have mission-critical data, it should be backed up at least once per hour. If your data is stored on cloud-based services, you should regularly back it up to an external storage device. Cloud-based services also let you restore older versions of files, which can be especially helpful in the event of an attack.
Other ways to reduce your risk of being hit with ransomware are to avoid clicking on links in emails or opening malicious attachments. Also, be careful of USB sticks that come from unknown sources. These devices often contain viruses and other malicious software. It’s also a good idea to update your NAS regularly.
If you do decide to protect your data against ransomware, be sure to implement a security protocol that will alert you when an attachment is malicious. This will give your employees the opportunity to assess whether an attachment is trustworthy before clicking on it.
The 3-2-1 rule is a general best practice for backup and recovery. This means that three copies of your data should be saved on two different types of media: the first should be an off-site backup and the second should be a local or network-connected backup. Having both of these backups available to you can provide the quickest and most reliable way to recover from an attack.
Using an automated threat detection system can help you maximize your chances of being protected, even when hackers are actively looking for new vulnerabilities. To get the most benefit from a security program, you should be monitoring your environment on a regular basis and performing frequent testing.
