Data Security Against Ransomware Attacks

Ransomware has dominated data protection over the past couple of years, but few people are aware that it is really the top of the iceberg. Everyone wants to safeguard their data from this new threat, but the majority of market-available solutions only prioritize relatively quick recovery (RTO) rather than detection, protection, and recovery. Recovery should actually be your last option.

More challenging to install than air gaps, immutable backup snapshots, and quick restore procedures are protection and detection mechanisms. These two phases of ransomware defense, however, bring up a world of new possibilities when done properly. They will eventually assist in protecting your data from cybersecurity risks like data exfiltration and modification, which are less frequent or, to put it another way, less noticeable in the news. Again, when I say that the incidences are less obvious, it's not only because they are not reported; frequently, no one even realizes they happened until it's too late!

Silos for security and data

The emergence of data silos is one of the main problems most organizations confront today because data growth has become commonplace. Sadly, new edge, multi-cloud, and hybrid infrastructures are doing little to change this. The proliferation of numerous, difficult-to-manage data infrastructure repositories in various places with various access and security policies is what we might refer to as "data silo sprawl." And because the environments are distinct and we don't have full control over them, there are frequently rules that don't always reflect the company's standards across these silos.

Many businesses still disregard various regulations, so you ought to give it some thought. Regulations like GDPR, CCPA, and others are now in effect everywhere and are quickly becoming a significant concern.

When authorities conduct an investigation, a corporation should be able to respond to a number of inquiries. They consist of:

• Can you properly protect data, especially personal information?
• Is it secure and well-defended against assaults?
• Is it kept in the proper nation or location?
• Do you have any idea who is using that data?
• When questioned, are you able to remove all the data you have on a person? The "right to be forgotten"

Can ransomware assaults be stopped?

Attacks do occur. The question is not whether, but rather when. Cybercriminals will continue to exploit weaknesses and devise novel ways to encrypt crucial data as long as they think your data has worth. Therefore, spending on rehabilitation is just as important as spending on prevention. Cyber resilience calls for integrating data protection within your cybersecurity system. Here are seven best practices that can lower your risk of a ransomware attack and prepare your company for a speedy recovery.

1. Utilize backup and disaster recovery tools

Every plan for cyber resilience should have a backup. Disaster recovery (DR) must be a part of the organization's plan because ransomware is a disaster scenario. Modern DR solutions offer fine-grained recovery checkpoints and the capacity to quickly restore entire sites or apps. Significantly lower recovery point objectives (RPOs) and quicker recovery time objectives are made possible by these technologies (RTOs).

It is still essential to use many layers of data protection utilizing the 3-2-1-1 rule. Keep three copies of your data, one offshore and the other offline, on two distinct types of media. Businesses that use backup and DR solutions to build an impenetrable, multi-layered defense can mitigate risks and resume operations much more quickly after encryption. You can easily adopt the 3-2-1-1 rule to secure data integrity and to maximize application uptime and data availability for your company using end-to-end data protection solutions, such as those provided by HPE.

2. Testing repeatedly to confirm recovery

Due to infrequent testing of their DR and backup solutions, the majority of enterprises are uncertain about their capacity to recover if an attack occurs. Organizations must rigorously test every recovery procedure, including failovers and file-level recoveries, in order to demonstrate their capacity for recovery. To ensure that administrators are adhering to procedures and documentation, especially during ransomware recovery simulations, mimic real disaster and recovery events.

3. Separate backup files

Encrypting, editing, or erasing an organization's data are the three sneaky methods that cybercriminals typically use to try and extract a ransom money. When ransomware modifies storage blocks for data, the altered, encrypted files are eventually backed up by your backup system.

Immutable backups effectively create a wall against ransomware assaults by keeping backed up data out of reach. Immutable backups are offered by systems like HPE StoreOnce Catalyst and cannot be encrypted, changed, or erased. The data is completely isolated by HPE's data protection solutions wherever it resides to guard against accidental or malicious tampering. These solutions are safe by default, preventing ransomware from seeing backup images and allowing data recoveries in the event of an attack. This ensures data integrity.
