Ransomware Protection: Focus on Backup and Recovery

Ransomware protection has been one of the main challenges faced by companies of all types, sizes and segments, and technology teams must be ready to take all necessary measures to minimize risks and ensure high availability of operations.

In August this year (2021), global consulting firm Accenture suffered a ransomware attack that threatened sensitive data. This made it another victim in a long line of organizations that have suffered from this type of attack in recent months.

Accenture was “lucky”. Prior to the incident, the company implemented security controls and protocols to protect its IT infrastructure against these threats and prepared a response against ransomware attacks.

As far as the company knows, no customer data or sensitive information was compromised after the attack.

However, many other companies have not been so lucky. Ransomware attacks add up to millions in lost revenue, recovery costs and ransom payments.

Even companies with required ransomware protection actions can still fall victim to attacks, a threat that continues to increase as ransomware becomes more sophisticated and adept at infecting backup data.

IT is under increasing pressure to ensure protection against Ransomware

A big challenge for companies that still struggle to implement effective policies and actions that include security, backup and recovery.

This is shown in Veeam’s Data Protection 2021 report, which points out that 58% of enterprise backups fail, leaving data unprotected against cyberattacks and cybercriminals.

Indeed, data backups and recovery procedures are the first line of defense for protection against Ransomware and other threats, but these backups must be fully protected.

This not only includes physical protections such as video surveillance or entry-exit logging, but also comprehensive storage and network security, which can include a wide range of protections.

An IT team, for example, can use vulnerability scanning, network segmentation, multi-factor authentication, network monitoring, intrusion detection systems and anti-malware/anti-ransomware software to ensure the protection of backups performed during companies’ business operations.

For an effective Ransomware protection, keep at least two copies of each backup

Store them on different types of media and locate them somewhere other than the primary network. At least one of these backups should be immutable and kept offline.

With an immutable backup, data can be written only once, usually in a single session, and cannot be updated or deleted, a strategy often referred to as WORM (write once, read many).

Along with these protections, IT teams must also ensure that all systems are patched and updated in a timely manner.

Backup protection should be part of the prevention strategy against ransomware attacks

The first step in preventing ransomware attacks is to review and update backup policies. These policies should reflect what data the organization has, where it is, and the systems that IT teams should recover first in the event of an attack.

Effective policies detail and validate everything that businesses need to back up and when those backups should occur. Perform data backup operations regularly and frequently, with critical data most of the time.

Also, check and analyze backups for infections. In practice, policies should specify how long to retain backups. Remember that ransomware can remain in the background for quite some time.

An organization should have a comprehensive monitor and alert system that tracks the entire technology backend, including endpoint and network environment, looking for anomalies in traffic, data patterns, user behavior and access attempts.

The protection framework created for the backup should be able to automatically respond to ransomware attacks

Such as quarantine of infected systems. These systems can use machine learning and other advanced technologies to identify and mitigate threats.

Ensure end users receive the education and training they need to minimize risky behavior and know what to do if they suspect their machines have been infected.

Don’t forget that IT teams should take all possible measures to reduce the network attack surface and limit the possibility of end-user actions resulting in ransomware.

Finally, to ensure efficient ransomware protection, IT teams should bring clean systems online, check which backups can be safely restored, and then recover data from those structures.

Once the systems are up and running, they should document lessons learned and take all necessary measures to reduce the risk of subsequent ransomware attacks.
