Previously, in the second blog of our four-part series discussing key tradeoffs for IT Operations to consider when comparing options for on-premises and cloud-based data protection operations, we covered ease of use and IT simplicity, which is arguably the biggest driver to the cloud. In this blog, we will cover the overarching topics of security and cyber-resiliency – arguably the biggest barriers to the cloud.

The first item relating to this topic that needs to be addressed is the issue of data placement and localization. That is, giving up, or at least limiting, control over where data is stored, and on what infrastructure it is stored (e.g., a dedicated or multi-tenant system) when moving off-premises. Especially when it comes to sensitive data, organizations have concerns – and, in many cases, have legislation they must comply with – about data privacy and sovereignty. Simply put, data might need to remain on premises for compliance purposes. That being said, service providers are working to address these challenges, with many certifying their solutions per compliance standards such as the Federal Risk and Authorization Management Program (FedRAMP) and the Health Insurance Portability and Accountability Act (HIPAA). In addition to looking for any pertinent compliance certifications, IT Operations should look for the ability to dictate where their data is stored (e.g., specific region) and for tenant isolation.

Alongside issues pertaining to lack of control over the data environment, we see concerns around lack of visibility and potentially insecure methods of data access, when moving off-premises. Especially as environments become multi- and hybrid-cloud by default, the threat landscape broadens greatly when moving off-premises. On-premises, IT teams have full autonomy to customize their security implementations to their specific needs, and this includes access control measures. Carrying best practices of providing “least privileged access” through to the cloud or other off-premises implementations with the same diligence and expertise is important.

On the flip side, as previously alluded to, cloud service providers have been building security-related technical capabilities and security teams that are robust. Especially given the staffing and expertise limitations touched upon in the previous blog, this is potentially a significant value-add for IT Operations teams. It can help to avoid potential misconfigurations, and it can help to implement, maintain, and update best-practice security measures such as encryption, firewalls, intrusion detection, and monitoring of the environment. As threats continue to evolve, this is not a small feat.

A cyber-resiliency-focused consideration for public cloud-hosted data protection infrastructure is the cross-region replication that providers use, which effectively builds in high levels of service availability. Additionally, replication, failover and failback for disaster recovery become easier; while people and expertise are both still required to make decisions regarding the environment’s architecture, the need to purchase, deploy and manage infrastructure is eliminated.

Along a similar vein, cloud-hosted “data vault’ solutions are coming in vogue – meaning they are being actively developed and pushed by vendors, and that they are increasingly in evaluation and in use by enterprises. They offer a potential alternative to traditional tape-based solutions for physical air gapping, but naturally, warrant close consideration by IT Operations for true isolation and cyber-resiliency. I personally audited two solutions – Cohesity FortKnox, and Dell PowerProtect Cyber Recovery (which has the option to be deployed on- or off-premises) – and my resulting reports offer key criteria for IT Operations to consider when evaluating these types of solutions specifically.

Security and cyber-resiliency are top-of-mind considerations across the board for IT Operations teams, especially given the onslaught of ransomware and data extortion. In addition to considering these tradeoffs between on- and off-premises solutions, data immutability, scanning for anomalous activity that could indicate nefarious activity, and the ability to monitor and audit data usage for suspicious behavior are table-stakes capabilities to consider regardless of the specific implementation.
