Backups are an important aspect of a recovery plan after a virus and ransomware disaster. When your organization is hit with ransomware, you can use backups to recover the system without much hassle.
However, backups are not immune to virus and ransomware attacks. There are advanced forms of ransomware that contain mechanisms intended to encrypt backup stored both in the cloud and locally. If your backups get encrypted, you might have no other option but to pay the ransom demanded by the attackers.
There are different approaches that you can implement to protect your backups from ransomware and virus attacks. They include:
Having Offline Backups
Having offline backups helps in protecting your business from intrusions and attacks. Attackers are always on the lookout for network attached storage (NAS) devices, such as an external hard drive. This threatens the security of your backup data.
Before, NAS devices were not a viable attack target but as ransomware is always evolving, you need to be on guard as attacks can happen when you least expect them. A constant state of readiness is the best protection. Therefore, to protect your backup, you need to have offline backups.
Restricting Traffic Over VPN
If you choose to back up your data on the cloud, you can lock down the storage for a given duration. This is called making the data immutable. You can limit traffic to a specific IP address and regulate VPN traffic by using access rules.
Once you finish backing up your data, the information cannot be changed for a period within which your data is safe. This solution will work with select storage providers.
Implementing the 3-2-1 Strategy
When you have more backups, you lower the risk of losing your business data. You should aim to maintain a minimum of three copies of your data. In case you lose any copy to ransomware and virus attacks, you will still have other copies.
