How Can Organizations Effectively Manage Cloud Security Risks?

It’s an exciting time to embrace cloud computing. The sheer number of cloud services and their innovative features and capabilities give organizations more visibility and control of their cloud environments than was possible even in the recent past. Cloud service providers (CSPs) are also building advanced security into their products, often rivaling or exceeding the security of on-premises infrastructures. Yet cloud security failures still happen, and when they do, there’s often a scramble to determine the cause and who should be held responsible. Organizations should also go a click deeper to ask, how could these failures have been prevented in the first place?

These questions are challenging considering the complexity of modern cybersecurity, but the answer lies in the delineation of responsibilities between customers and their CSPs, as well as the importance of human oversight when managing technology.

Avoid Presumptions Regarding Responsibilities

Many cloud users fall into two camps with their approach to cloud security. On one end are cautious security leaders wary of potential vulnerabilities, while on the opposite side are those who blindly trust CSPs to handle all security needs. However, the best stance is one of balanced vigilance. Many security concerns arise from user misconfigurations rather than an inherent lack in the CSP’s security infrastructure. In fact, Gartner revealed a startling statistic that through 2025, 99% of cloud security failures will be the customer’s fault. Although CSPs offer robust security measures, users must fully understand and adequately implement them to mitigate risks effectively.

This is where common misconceptions come into play. Some organizations may believe that once they move their data to the cloud, their security responsibilities are entirely absorbed by their cloud provider. This misunderstanding leads to a false sense of security and potentially leaves significant vulnerabilities unaddressed. The shared responsibility model demarcates the division of security roles, but ensuring that all responsibilities are covered necessitates proactive customer involvement.

Thoroughly Review CSP’s Service Level Agreement (SLA)

The shared responsibility model indicates that cloud security is a cooperative effort. Both parties need to clearly comprehend their roles and obligations from the outset. This clarity is often buried in the Service Level Agreement (SLA), a critical document that outlines the CSP’s duties and the customer’s responsibilities. Before committing to a CSP, it’s essential for organizations to spend time deeply understanding and reviewing the fine print of the SLA. Ignoring or skimming through these details can lead to costly misunderstandings and vulnerabilities down the line.

Cloud service providers generally take on the task of securing the host infrastructure, physical facilities, and certain aspects of network security. However, customers are responsible for endpoint security, identity and access management, and data protection within the cloud. Misinterpretations of these responsibilities can lead to significant security lapses and an unattributed blame game when breaches occur. Only by thoroughly understanding and agreeing to the terms of the SLA can organizations ensure that their security policies align with those of their CSP and that nothing falls through the cracks.

Employ Security Experts with Cloud Specialization

The intricacies of cloud security necessitate a specialized skill set. Traditional IT and security teams may possess a solid understanding of on-premises solutions, but cloud security poses unique challenges that require distinct expertise. Therefore, hiring or training security professionals with specific knowledge in cloud environments is a paramount step in managing risk effectively. These experts are better equipped to interpret cloud security frameworks, handle dynamic security configurations, and respond to cloud-specific threats swiftly.

In practice, security leaders with cloud expertise bring an additional layer of strategic oversight. They can ensure that security settings are properly configured from the start and continuously adjusted as needed. Moreover, they contribute to ongoing security assessments and audits, which help identify and address potential vulnerabilities proactively. By investing in cloud security knowledge, organizations empower themselves with the insights needed to navigate the complex landscape of cloud threats and defenses.

Perform Routine Security Evaluations

The shared responsibility model emphasizes that cloud security is a collective effort between cloud service providers (CSPs) and their customers. Both parties must thoroughly understand their respective roles and obligations from the start. This essential clarity is usually outlined in the Service Level Agreement (SLA), a crucial document detailing both the CSP’s duties and the customer’s responsibilities. Before committing to any CSP, organizations should meticulously review the fine print of the SLA. Overlooking these details can result in costly mistakes and security vulnerabilities down the road.

CSPs are typically in charge of securing the host infrastructure, physical facilities, and some aspects of network security. On the other hand, customers are responsible for securing endpoints, managing identities and access, and protecting data within the cloud. Misunderstanding these roles can lead to significant security breaches and an unattributable blame game when incidents occur. To ensure alignment between an organization’s security policies and those of their CSP, a thorough comprehension and agreement to the SLA terms are crucial. Only then can both parties effectively ensure that no security responsibilities are overlooked.
