Overview of cloud security threats

As cloud adoption continues to grow, so does the sophistication of threats targeting cloud environments. Some common cloud security challenges include:

• Data breaches
• Insider threats
• Misconfigured cloud services
• Account hijacking
• Denial of Service (DoS) attacks

Key components of cloud security

Cloud security encompasses several critical components that work together to protect data, applications, and infrastructure in cloud environments. Understanding these key elements is crucial for implementing effective cloud security strategies and protecting your cloud assets.

1. Identity and Access Management (IAM)

Identity and Access Management (IAM) is the cornerstone of cloud security, controlling who can access your cloud resources and what actions they can perform. It involves user authentication, authorization, and access control policies. Implementing strong IAM practices helps prevent unauthorized access and reduces the risk of data breaches.

2. Data Loss Prevention (DLP)

Data Loss Prevention (DLP) can help you gain visibility into the data you store and process by providing capabilities to automatically discover, classify, and de-identify regulated cloud data. DLP technologies safeguard sensitive information from unauthorized access, use, or transmission. They monitor and control data in motion, at rest, and in use, helping organizations comply with regulations and protect intellectual property. DLP is essential in addressing cloud security challenges related to data protection and privacy.

3. Security Information and Event Management (SIEM)

Security Information and Event Management (SIEM) systems collect and analyze log data from various sources across your cloud infrastructure. They provide real-time monitoring, threat detection, and incident response capabilities. SIEM is crucial for maintaining visibility into your cloud environment and identifying potential security threats.

4. Encryption and data protection

Encryption is a fundamental aspect of cloud security, ensuring data confidentiality both in transit and at rest. It involves using cryptographic algorithms to convert data into unreadable formats, protecting it from unauthorized access.

2025 State of Cloud Security Report

Key findings and trends

The 2025 State of Cloud Security Report reveals a cloud security landscape defined by rapid innovation and rising complexity. As organizations embrace multi-cloud and AI-driven environments, the scale and interconnectivity of risks continue to expand.

More than half of organizations (55%) now use two or more cloud providers, and 84% use AI in the cloud, yet 62% have at least one vulnerable AI package. Traditional risks persist as well: nearly a third of all cloud assets remain neglected or unpatched, and each contains an average of 115 vulnerabilities. Data exposure is also on the rise, with more than a third of organizations leaving sensitive databases publicly accessible.

These findings underscore the Defender’s Paradox: attackers need to be right only once, while defenders must secure every path. In fact, 13% of organizations have a single cloud asset responsible for more than 1,000 attack paths, highlighting the need for unified visibility, contextual prioritization, and AI-driven defenses across the entire application lifecycle.

Key recommendations

The report also summarizes key recommendations on how organizations can reduce their cloud attack surface and harden their environments. This includes the following activities:

• Secure AI while leveraging it for defense: Protect your environment from AI-related risks by securing models, data, and dependencies using cloud security best practices. At the same time, use AI to enhance detection, remediation, and least-privilege enforcement..
• Protect high-value assets: Continuously identify and monitor your organization’s “crown jewels.” Prioritize remediation of the attack paths that endanger them, ensuring real-time protection for sensitive and business-critical resources.
• Safeguard sensitive data: Locate where sensitive data resides across your cloud estate and apply the appropriate controls to keep it secure and compliant. Continuously monitor for unusual access or exfiltration attempts.
• Prevent workload neglect: Maintain a current inventory of workloads and monitor for unpatched or abandoned assets. Deploy only supported applications and operating systems, and enforce IaC security benchmarks before deployment.
• Prioritize patching strategically: Focus on remediating critical vulnerabilities that are exploitable in runtime rather than attempting to patch everything. .
• Enforce the Principle of Least Privilege (PoLP): Grant users and non-human identities only the minimum permissions needed. Use automation and AI-driven IAM capabilities, including Just-in-Time (JIT) Access, to reduce standing privileges and enforce least privilege at scale.
• Unify security before deployment and during runtime: Implement security that combines runtime protection with pre-deployment security scanning. Detect and remediate issues earlier in the application pipeline, trace production alerts back to source code, and maintain full visibility across the application lifecycle.
• Continuously audit and monitor: Conduct regular audits, enforce security baselines, and continuously monitor access logs for anomalies to detect and respond to threats faster.

Cloud security challenges

As organizations increasingly adopt cloud technologies, they face several significant hurdles in maintaining robust security. Understanding these challenges is crucial for implementing effective cloud security measures and safeguarding your digital assets.

Lack of visibility

One of the biggest cloud security issues that firms face is a lack of visibility into their cloud environments, which include digital assets, infrastructure, and data. Unlike on-premise infrastructure, cloud environments are dynamic and constantly changing, with more users able to create ephemeral resources such as containers and serverless functions that demand protection and expand an organization’s attack surface. This makes it difficult for security teams to gain or maintain visibility into their cloud environments, not to mention adequately secure them.

Multi-tenancy issues

Multi-tenancy problems develop when multiple customers share the same cloud infrastructure, which may raise distinct security risks. While cloud companies take precautions to protect customer data, the risk of data loss or unauthorized access remains a concern. A vulnerability in one tenant’s environment could expose others to possible intrusions, making multi-tenancy a major challenge in cloud security. Organizations must therefore carefully assess their cloud provider’s safety measures in order to offer proper protection in shared environments.

Access management and shadow IT

Managing user permissions across cloud services can be challenging, especially with the use of multiple vendors and platforms. The rise of remote work and distributed teams adds to this complexity. Additionally, the ease of adopting cloud services has led to an increase in shadow IT, where employees use unapproved applications. This can jeopardize data security and compliance, as these unsanctioned tools are often neglected or poorly protected.

To effectively manage access in a cloud environment, companies must address the challenges posed by shadow IT and ensure that all software used by employees is approved and secure. This approach not only helps protect data but also ensures compliance with relevant standards.

Compliance and regulatory concerns

Adhering to industry regulations and data protection laws becomes more challenging in cloud environments. Organizations must ensure their cloud providers meet specific compliance requirements and implement appropriate controls to protect sensitive data. This is particularly crucial when dealing with cross-border data transfers and varying international regulations.

Misconfigurations and human error

Cloud security challenges often come from simple misconfigurations or human mistakes. The complexity of cloud systems and the rapid pace of changes can easily lead to overlooked security settings or incorrect access controls. These missteps create vulnerabilities that bad actors might exploit, underscoring the need for strong security practices and continuous monitoring.

Types of cloud security solutions

Cloud security refers to a broad range of technologies, philosophies, and vendors. Various types of cloud security solutions exist, and each one presents significant differences that can greatly impact your overall security.

Public vs. Private vs. Hybrid Cloud Security

When discussing cloud security, understanding the security implications of different cloud deployment models is crucial. Think of it like choosing your living arrangement:

• Public cloud security is akin to living in an apartment building where everyone shares the same resources. In this setup, companies depend on shared infrastructure provided by major players like Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure. While these providers invest heavily in security measures, the responsibility for securing data ultimately lies with each business. For example, a startup might choose a public cloud to host its application, but it must implement robust access controls and encryption to keep customer data secure and private.
• Private cloud security resembles owning a standalone house. Here, organizations gain exclusive control over their infrastructure, allowing them to customize security measures to meet their specific needs. This model is particularly beneficial for industries dealing with sensitive data, such as healthcare or finance. For instance, a financial institution might select a private cloud to ensure that customer financial records are stored securely and comply with regulations like PCI DSS.
• Hybrid cloud security offers flexibility similar to having a primary residence and vacation home. In this model, businesses can store sensitive data in a private cloud or on-prem environment while leveraging the scalability of a public cloud for other operations. For example, a retail company might keep customer payment data in a private cloud for added security while using a public cloud for marketing analytics. This approach requires a unified security strategy to effectively protect data across all environments.

Best practices for implementing cloud security

Implementing robust cloud security measures is crucial for protecting your organization’s data and assets in the cloud. By following these best practices, you can significantly enhance your cloud security posture and mitigate potential risks.

Focus on comprehensive coverage and risk detection

You can only protect what you can see. Equip your security teams with advanced tools that provide complete visibility into your cloud environments, including any containers and serverless functions that users may add in the future. Combine this with technology that detects all types of cloud security risks, as these dynamic environments can be vulnerable to various interconnected threats. This comprehensive approach helps you counter attackers’ freedom of movement and multi-phased attacks effectively.

Configure your settings

No two cloud environments are alike. Each organization has unique needs when it comes to cloud security, so don’t take a one-size-fits-all approach. After acquiring advanced cloud security technology, tailor it to align with your specific goals and conditions. For instance, configure features that automate processes, customize alerts for specific risk types, and enable ready-made compliance templates to enhance your security posture effectively. Also, configure any preventative settings in your cloud security solution that block issues in development and prevent them from reaching production.

Leverage integrations and minimize cross-functional friction

In many organizations, tensions often run high between development, DevOps, and security teams. Security teams depend on developers to resolve issues, while developers grapple with tight timelines and the pressure to deliver code quickly. These interactions typically require developers to fix problems when they are most costly and time-consuming. To alleviate this friction, leverage integrations that make it seamless for security and development teams to collaborate. Best practice is to take advantage of integrations that allow developers to use their existing tools and processes, eliminating the need to learn or login to a separate platform.

Protect high-value assets with real-time detection and monitoring

Adding real-time runtime protection to your most sensitive workloads is a practical way to strengthen your overall cloud defense. While this type of security doesn’t provide complete visibility or address hygiene issues such as misconfigurations or overprivileged identities, it serves as a powerful safeguard against active threats. By continuously monitoring runtime behavior and detecting potential threats and activity, it enables organizations to prevent attacks from escalating into severe incidents.

Treat compliance as a continuous requirement

Compliance drift—when organizations gradually stray from adhering to standards and controls—is a common challenge. This often occurs when companies view compliance as a one-time event focused solely on passing audits, rather than an ongoing responsibility that reflects their security effectiveness. As a result, they waste valuable time and resources scrambling to prepare for audits or managing the fallout from violations. To combat this, embrace compliance as a continuous process. This means not only leveraging advanced technology to automate tasks and processes but also prioritizing compliance as an ongoing business objective.

Educate staff

Train your staff on cloud security best practices and potential risks. Hold regular training sessions to keep employees informed about the latest threats and security protocols. Building a security-conscious culture within your team is vital for maintaining a strong cloud security posture.

By adopting these best practices, you can significantly reduce the risk of data breaches and other security incidents. Keep in mind that cloud security is an ongoing process that demands continuous attention to evolving threats and technologies.

The future of cloud security

AI-driven solutions are set to enhance and expand existing capabilities while alleviating the burden on overwhelmed security teams.
