Securing valuable business data is a top concern for organizations, and many have turned to cloud computing as a solution. However, recent incidents have highlighted the vulnerabilities of cloud-based storage, emphasizing the need for businesses to rethink their data management strategies.
One notable example occurred in May 2024 when an Australian financial service provider experienced a misconfiguration issue that resulted in the deletion of their Google Cloud account. This incident left over half a million customers without access to their financial data for an entire week. This demonstrates that even the most reputed cloud computing services are susceptible to data mismanagement and its consequences.
Another incident involved a ransomware attack on Finland-based cloud service provider Tietoevry. This cyberattack affected private companies, universities, and government authorities across Sweden, showcasing the wide-ranging impact of cloud vulnerabilities.
These incidents serve as a reminder that data stored in the cloud is not immune to risks, just like locally stored data. Cloud computing services rely on servers housed in data centers, which are susceptible to physical threats like fires and cyber threats like cyberattacks. It is crucial for businesses to recognize these risks and take steps to mitigate them.
The evolving regulatory landscape further emphasizes the importance of proper data management. Regulatory authorities are implementing stricter measures to ensure the handling of data and digital infrastructure is secure. For example, the Digital Operational Resilience Act (DORA) and the Network and Information Systems Directive (NIS2) in the European Union aim to enhance cybersecurity in critical sectors. Companies that fail to comply with these regulations can face significant penalties and damage to their reputation.
To address these challenges, businesses must reevaluate their data management strategies. Relying solely on third-party cloud storage solutions without implementing internal controls is no longer sufficient. Adopting a zero-trust approach to data backup is essential for protecting valuable data.
A robust backup strategy should not only protect against data loss due to data center outages but also safeguard against ransomware and cross-site scripting attacks. Businesses should retain backups that are older than six months to ensure historical data and logs are readily available for forensic purposes. Employing a combination of base backups, Write Ahead Log (WAL) backups, full system snapshots, and full data dumps ensures incremental data security.
In addition to the type of backups used, the geographical location of backups is also important. Storing identical backups in different geographical locations, ideally at least 25 miles apart, minimizes the risk of localized cyberattacks or disasters like fires.
However, implementing technical measures alone is not enough. Access to backups should be restricted to authorized personnel, and encryption should be applied to maintain data integrity and confidentiality. Keeping a detailed log of all backup instances aids in tracking and auditing purposes.
Regular assessments are crucial to ensuring the reliability and consistency of backup processes. Monthly verification of backup systems and an annual full recovery test are necessary to validate the effectiveness of the backup strategy. Simulating realistic disaster recovery scenarios annually helps identify potential gaps in the backup plan, allowing businesses to address vulnerabilities proactively.
By embracing these measures, businesses can enhance the security of their data assets while complying with stringent regulations. Achieving true data security in the cloud requires a zero-trust approach, which means trusting no one and implementing rigorous internal controls.
In conclusion, the safety of data stored in the cloud is not guaranteed. Businesses must be proactive in implementing robust data management strategies to protect against potential risks and comply with evolving regulations. This requires a combination of technical measures, such as secure backups and encryption, as well as stringent internal controls. Taking these steps will ensure the security and resilience of valuable business data in an increasingly digital and interconnected world.
