Todays organizations desire the accessibility and flexibility of the cloud, yet these benefits ultimately mean little if youre not operating securely. One misconfigured server and your company may be looking at financial or reputational damage that takes years to overcome.

Fortunately, theres no reason why cloud computing cant be done securely. You need to recognize the most critical cloud security challenges and develop a strategy for minimizing these risks. By doing so, you can get ahead of problems before they start, and help ensure that your security posture is strong enough to keep your core assets safe in any environment.

With that in mind, lets dive into the five most pressing cloud security challenges faced by modern organizations.

According to Gartner, the shift to cloud computing will generate roughly $1.3 trillion in IT spending by 2022. The vast majority of enterprise workloads are now run on public, private or hybrid cloud environments.

Yet if organizations heedlessly race to migrate without making security a primary consideration, critical assets can be left unprotected and exposed to potential compromise. To ensure that migration does not create unnecessary risks, its important to:

Effectively managing and defining the roles, privileges and responsibilities of various network users is a critical objective for maintaining robust security. This means giving the right users the right access to the right assets in the appropriate context.

As workers come and go and roles change, this mandate can be quite a challenge, especially in the context of the cloud, where data can be accessed from anywhere. Fortunately, technology has improved our ability to track activities, adjust roles and enforce policies in a way that minimizes risk.

Todays organizations have no shortage of end-to-end solutions for identity governance and management. Yet its important to understand that these tools alone are not the answer. No governance or management product can provide perfect protection as organizations are eternally at the mercy of human error. To help support smart identity and access management, its critical to have a layered and active approach to managing and mitigating security vulnerabilities that will inevitably arise.

Taking steps like practicing the principle of least privilege by permitting only the minimal amount of access necessary to perform tasks will greatly enhance your security posture.

The explosive growth of cloud computing has highlighted new and deeper relationships between businesses and vendors, as organizations seek to maximize efficiencies through outsourcing and vendors assume more important roles in business operations. Effectively managing vendor relations within the context of the cloud is a core challenge for businesses moving forward.

Why? Because integrating third-party vendors often substantially raises cybersecurity risk. A Ponemon institute study in 2018 noted that nearly 60% of companies surveyed had encountered a breach due to a third-party. APT groups have adopted a strategy of targeting large enterprises via such smaller partners, where security is often weaker. Adversaries know youre only as strong as your weakest link and take the least path of resistance to compromise assets. Due to this, it is incumbent upon todays organizations to vigorously and securely manage third-party vendor relations in the cloud. This means developing appropriate guidance for SaaS operations (including sourcing and procurement solutions) and undertaking periodic vendor security evaluations.

APIs are the key to successful cloud integration and interoperability. Yet insecure APIs are also one of the most significant threats to cloud security. Adversaries can exploit an open line of communication and steal valuable private data by compromising APIs. How often does this really occur? Consider this: By 2022, Gartner predicts insecure APIs will be the vector most commonly used to target enterprise application data.

With APIs growing ever more critical, attackers will continue to use tactics such as exploiting inadequate authentications or planting vulnerabilities within open source code, creating the possibility of devastating supply chain attacks. To minimize the odds of this occurring, developers should design APIs with proper authentication and access control in mind and seek to maintain as much visibility as possible into the enterprise security environment. This will allow for the quick identification and remediation of such API risks.

Weve mentioned visibility on multiple occasions in this article and for good reason. It is one of the keys to operating securely in the cloud. The ability to tell friend from foe (or authorized user from unauthorized user) is a prerequisite for protecting the cloud. Unfortunately, thats a challenging task as cloud environments grow larger, busier and more complex.

Controlling shadow IT and maintaining better user visibility via behavior analytics and other tools should be a top priority for organizations. Given the lack of visibility across many contexts within cloud environments, its a smart play to develop a security posture that is dedicated to continuous improvement and supported by continuous testing and monitoring.

Cloud security is achievable as long as you understand, anticipate and address the most significant challenges posed by migration and operation. By following the ideas outlined above, your organization will be in a much stronger position to prevent and defeat even the most determined adversaries.
