How to Safeguard Your Backups Against Ransomware: Proven Strategies

Ransomware attacks have surged by over 150% in recent years, with backup systems being prime targets. Without proper protection, ransomware can encrypt or delete backups, leaving businesses with no way to recover critical data. In fact, 70% of organizations affected by ransomware experience significant downtime due to unprotected backups.

Ensuring your ransomware backup is safe is essential to maintaining business continuity. This guide covers proven strategies.

Don't wait until it's too late – secure your backups now to stay protected from evolving ransomware threats.

Ransomware and Backup Security

Ransomware is a type of malicious software that encrypts or locks files on a computer system, making them inaccessible to the user until a ransom is paid to the attacker. Ransomware attacks have become increasingly prevalent and sophisticated, posing a significant threat to individuals and organizations alike.

Backups are a primary target for ransomware attacks because they represent a critical line of defense against data loss. By encrypting or deleting backups, ransomware attackers can significantly increase the pressure on victims to pay the ransom, as they may have no other means to recover their data.

How Ransomware Infiltrates Backups

Ransomware can penetrate backups through different strategies, making it possible for the virus to encrypt or delete them and make them useless. An approach often witnessed is developing a weakness in the backup software or in the operating systems that contain the backups. Hackers are constantly on the prowl for security vulnerabilities that will enable them to gain access to backup storage depots.

Another strategy is to penetrate user accounts or exploit misconfiguration, which allow ransomware to obtain the rights needed to read and modify backup files. Phishing, brute force, and stolen or weak passwords are the common causes of this type of unauthorized access.

When ransomware penetrates a backup environment, it can use different tricks to make backups ineffective.

Proven Strategies to Safeguard Your Backups

Regularly Scheduled Backups

They serve as a protective measure against data loss due to ransomware intrusion or any other system calamity. Frequent backups minimize the risks of data loss in case of an attack or any other disruption. Synchronization’s key use stems from its ability to provide up-to-date data for use in contingencies. Both automatic and manual backup options are available. The system initiates the backup daily, weekly, or monthly, and there is no likelihood of human interference. Other settings also increase, ensuring backups do occur, which are set and then run independently of the user’s input.

Implementing the 3-2-1 Backup Rule

One of the best and longest-standing methods of safeguarding backup is the 3-2-1 rule. This approach suggests that you should have three copies of your data: the original and two backups. These backups should be saved separately on at least two different storage media (DVDs, external drives, cloud services, etc.); one of these copies should be kept in a different physical location or isolated from the main system.

Use of Immutable Backups

Immutable backups are set ones that cannot be changed, deleted, or encrypted, regardless of the ransomware attacks. Once data has been written, it cannot be modified and remains permanently embedded in the medium in which the writing took place. This renders ransomware unable to access or modify these backups, giving a dependable reference point in instances of attack.

Air-Gapped Backups

An air-gapped system is not connected to any network to ensure that ransomware and other forms of cyber threats cannot tamper with the backup. More often, in the air-gapped network environment, backup copies are created on devices that are not connected to the internet or the local network and are thereby safe.

Encryption and Secure Access Controls

Encryption is a necessary security measure for backing up. This ensures that even if attackers manage to penetrate your network and encrypt your data or get their hands on your backups, they cannot use the data effectively due to its encrypted nature.

Regularly Testing Backup Integrity

It is crucial to always have a backup plan in place, but it is equally essential to perform periodic tests that would confirm the effectiveness of the backup. This way, you are assured that the backups that you are working with are not only full, recent, and uncorrupted.
