Over the past few weeks, we embarked on a mission to implement a staggering 710 security and compliance controls across seven key standards relevant to public cloud environments. Our aim was precise: achieve an 80% compliance rate, a significant leap from the initial 15% we started with. However, as we progressed towards this goal, we uncovered some unsettling truths about the costs involved.
One might assume that the primary costs in the cloud are tied to computing and storage. However, as compliance percentages rise, the landscape shifts. Shockingly, a significant 40% of our total costs were attributed to threat prevention services and monitoring. Is it possible that cloud providers exploit an organisation's vulnerabilities for profit?
The cloud offers unparalleled flexibility, but network security remains a daunting challenge. Adhering to cloud policies for network security can lead to a staggering 200% cost increase. It begs the question: Is the convenience of the cloud worth this financial burden?
As we journeyed towards an 85% compliance score, we encountered a startling revelation: our cloud services costs escalated by a jaw-dropping 300%. At this stage, security became the elephant in the room, dominating the expense sheet.
Amidst the turmoil of escalating costs, we identified a beacon of hope. The most impactful security controls, those with the potential to thwart ransomware and data leaks, revolved around identity and access lifecycle management. These controls were not only practical but also relatively easier to implement.
We also compared various security standards, including SOC-TSP, NIST-SP-800-53-R5, ISO-27001:2013, Azure-Security-Benchmark, Azure-CIS-1.3.0, PCI-DSS-3.2.1, and NIST-SP-800-53-R4. Surprisingly, the Azure security benchmark emerged as the easiest to implement, primarily promoting Azure service consumption. Achieving 90% compliance with NIST R4 controls translated to roughly 60% compliance with ISO-27001 despite ISO having fewer controls.
Another eye-opener in our journey was the hidden costs of monitoring and logging in the cloud. Cloud vendors structure their findings to promote their services, often leading to increased expenses. They also charge for data logging, log movement, and overall network usage. This practice raises questions about transparency and fairness in cost structures.
Cloud vendors can impose private endpoints, further complicating network security and increasing costs. Compliance, even a seemingly small increase from 80% to 88%, can lead to a 33% rise in expenses. To meet these stringent compliance requirements, we found ourselves compelled to invest in reserved instances for three years, covering almost all Compute resources. However, the actual cost and licensing per core remained elusive and non-transparent.
In conclusion, our journey through the complexities of cloud security and compliance uncovered a few critical lessons. Organisations must exercise caution regarding costs, refraining from blind trust in cloud provider scores and recommendations. Establishing a dedicated governance team that weighs the delicate balance between cost and security impact is essential.
