Cloud computing powers everything from remote work to large-scale data analytics. But its vulnerabilities continue to challenge organizations of all sizes.
The rapid development of cloud technologies often outpaces security measures, creating opportunities for risk. Whether it’s misconfigured settings, unauthorized access, or overlooked third-party risks, cloud vulnerabilities can lead to significant security issues.
Before your team can address these challenges and secure your cloud applications, you need to know what you’re up against.
Vulnerabilities in cloud computing are weaknesses or gaps in cloud systems or services that cybercriminals can exploit. These vulnerabilities often stem from misconfigurations, poor access controls, or insufficient monitoring and visibility.
A key challenge with cloud security lies in its shared responsibility model. The cloud service provider secures the underlying infrastructure, but you still have to safeguard your data, configurations, and user access. Vulnerabilities arise when teams neglect this balance and rely only on the service provider to protect their information.
The complexity of cloud environments further compounds the issue. Businesses often use multiple cloud services across different providers, each with its own tools, settings, and security protocols. This fragmented setup creates blind spots, making it harder to spot misconfigurations or enforce consistent security policies across the board. Following structured risk assessment practices helps you address these blind spots systematically.
Every advantage comes with a risk, and cloud environments are no exception. Below are eight vulnerabilities and emerging trends affecting cloud security, how they pose risks, and the steps you can take to address them.
What it is: Misconfigurations remain one of the leading causes of cloud breaches, often stemming from human error, a lack of familiarity with cloud platforms, or the sheer complexity of managing multiple environments.
For example, storage buckets left publicly accessible or with overly permissive access controls allow attackers to gain unauthorized entry to sensitive data. Similarly, misconfigured network security groups might inadvertently expose critical systems to the Internet.
Why it matters: A single misconfiguration can lead to large-scale data breaches and reputational damage.
How to address it:
What it is: Identity and access management (IAM) missteps—like weak passwords, overly permissive roles, or lack of multi-factor authentication (MFA)—are prime targets for attackers.
Cloud computing security breaches have shown that compromised credentials are often the entry point for sophisticated cloud attacks. Stolen passwords and poorly managed third-party accounts grant attackers unrestricted access to assets. Teams often don’t notice these missteps until they cause significant damage.
Why it matters: Poor access controls allow attackers to escalate privileges, exfiltrate data, and disrupt services.
How to address it:
What it is: Shadow IT refers to cloud resources or services deployed without IT department approval. While employees may have good intentions—like increasing productivity—unauthorized tools create security blind spots.
For example, an employee might use an unapproved cloud storage service to share files, inadvertently exposing sensitive data if the service lacks proper encryption and security settings.
Why it matters: Shadow IT bypasses organizational security policies, leaving data and systems vulnerable to breaches.
How to address it:
What it is: APIs are the backbone of cloud communication, but that makes them a significant attack vector. Poorly secured APIs allow attackers to bypass authentication, manipulate data, or launch denial-of-service (DoS) attacks. For instance, an exposed API key in a public repository could grant attackers unauthorized access to cloud services.
Why it matters: APIs offer attackers direct access to cloud resources and sensitive data.
How to address it:
What it is: Zero-day vulnerabilities are software flaws unknown to vendors but exploited by attackers. These vulnerabilities enable sophisticated cloud-based attacks and can have widespread consequences in a cloud context, especially when multiple customers share the same infrastructure.
Why it matters: Zero-day exploits can cause significant damage before patches become available.
How to address it:
What it is: Managing visibility across sprawling cloud environments—often spread across multiple providers—is challenging. Misconfigurations, unauthorized access, and malicious activity can go unnoticed without proper oversight. Something like an overlooked misconfigured storage bucket could remain exposed for months before detection.
Why it matters: Security teams can’t detect or respond to threats promptly without visibility.
How to address it:
What it is: Insider threats—accidental or malicious—pose significant risks to cloud security. These threats often stem from disgruntled employees, compromised accounts, or careless handling of sensitive information. For example, an employee with lingering access and compromised passwords could delete cloud storage resources or leak confidential information.
Why it matters: Insiders have legitimate access, making it harder to detect malicious activity.
How to address it:
What it is: Cloud environments generate vast amounts of logs and telemetry data, and threats can slip through the cracks without proper monitoring. Many organizations lack centralized monitoring tools, preventing security teams from detecting or responding to anomalies effectively. An attacker could exploit a misconfigured storage bucket or compromised credentials and remain undetected for weeks, slowly exfiltrating data.
Why it matters: Without sufficient monitoring and real-time alerts, threats go unnoticed until significant damage has been done.
