The surge in ransomware attacks over the last 12 months has made the threat a ‘when’ rather than an ‘if’. Ransomware is a threat to organisations of all sizes and with the increase in remote working organisations can no longer rely on a company firewall to protect their data and applications.
A holistic approach to ransomware defence is crucial to help keep your organisation protected and ensuring you have an immutable architecture can help accelerate your recovery should you be compromised.
Backups are one of the most, if not the most, important defences against a ransomware attack but it is vital that your backups are clean and up to date to ensure you can recover data effectively. It is best practice to use immutable backups to protect against them being compromised, encrypted or deleted.
Knowing that backups are an organisations best defence and that many organisations do not have the right solutions in place to protect them, malicious attackers are targeting backups. If they can encrypt or delete backups, then their victims have little choice but to pay the ransom.
But with the right protection and defences in place, organisations can strengthen their security posture and ensure that their backups are safeguarded. So should they fall victim to a breach they can restore their data and be back up and running in little time.
MTI partner Rubrik delivers a uniquely immutable filesystem natively to prevent unauthorised access to backups to help organisations make a rapid recovery following a ransomware breach – with minimal business disruption and without paying hefty ransoms.
Immutable backups
By design the Rubrik Ransomware Recovery utilises multi-layered data security by encrypting all data at rest and in transit. Data is transferred to and from a protection client using strong randomised password authenticated APIs. Leveraging the TLS 1.2 protocol for both data transfers and node-to-node communication certification.
All data is then stored in an immutable format, meaning that it can’t be altered and prevents ransomware from accessing, encrypting or deleting the backups. True immutability is critical for an effective ransomware protection strategy.
Instant recovery
The longer an organisation takes to get hold of the situation and recover from a ransomware attack the more damage it is likely to do financially and to their reputation. It is crucial that organisations have the solutions in place that can help them recover quickly.
Rubrik keep the recovery time objective (RTO) to a minimum through incremental-forever backups and point-in-time recovery options, making it quick and easy to restore data. With just a few clicks, Rubrik Ransom Recovery can restore data to the most recent clean state, whether you need to perform a full or partial system restore.
Having the ability to recovery rapidly will reduce business downtime and can help to achieve productivity savings. Rubrik Ransom Recovery can also integrate Radar and Sonar into popular SIEM, Syslog or security automation frameworks using APIs for automated recoveries and enriched intelligence.
Impact visibility
Knowing the exact point-in-time copy that is deemed clean from all malware is essential for a speedy recovery. This fast, accurate visibility determines the backup to restore and can save valuable time.
Following an attack, Rubrik automatically diagnoses its impact scope to provide a clear view of which data has been compromised and where it resides. It can also identify if certain personally identifiable information or protected health information has been exposed so the necessary actions can be taken quickly.
While Radar isn’t need for ransomware recovery, it does provide a higher level of visibility into recovery options and a greater level of intelligence to make recovery faster. Radar also monitors behaviours and creates a baseline that behaviours can be measured against to detect anomalies and highlight potential breaches.
Build a robust ransomware remediation plan
Having clean backups is one of the best defences your organisation can have to protect against ransomware attacks. Should you suffer a breach, backups enable you to recover quickly and effectively with minimal disruption or damage, and without having to pay a ransom.
Building a robust ransomware remediation plan can help ensure that your organisation has the right processes and plans in place to accelerate recovery.
