The increase in cloud adoption has been met with a corresponding rise in cybersecurity threats. Cloud intrusions escalated by a staggering 75% in 2023, with cloud-conscious cases increasing by 110%. Amid this surge, eCrime adversaries have become the top threat actors targeting the cloud, accounting for 84% of adversary-attributed cloud-conscious intrusions. 

For large enterprises that want to maintain the agility of the cloud, it’s often difficult to ensure DevOps teams consistently scan images for vulnerabilities before deployment. Unscanned images could potentially leave critical applications exposed to a breach. This gap in security oversight requires a solution capable of assessing containers already deployed, particularly those with unscanned images or without access to the registry information. 

Recognizing this need, cloud security leader CrowdStrike has enhanced its CrowdStrike Falcon® Cloud Security capabilities to ensure organizations can protect their cloud workloads throughout the entire software development lifecycle and effectively combat adversaries targeting the cloud. Today we’re releasing two new features to help security and DevOps teams secure everything they build in the cloud.

Assess Images for Risks Before Deployment

We have released Falcon Cloud Security Image Assessment at Runtime (IAR) along with additional policy and registry customization tools. 

While pre-deployment image scanning is essential, organizations that only focus on this aspect of application development may create a security gap for containers that are deployed without prior scanning or lack registry information. These security gaps are not uncommon and could be exploited if left unaddressed.

IAR will address this issue by offering: 

• Continuous security posture: By assessing images at runtime, organizations can maintain a continuous security posture throughout the software development lifecycle, identifying and mitigating threats in real time even after containers are deployed.
• Runtime vulnerability and malware detection: IAR identifies vulnerabilities, malware and secrets, providing a holistic view of the security health of containers. This will help organizations take preventative actions on potential threats to their containers. 
• Comprehensive coverage: If containers are launched with unscanned images, or if the registry information is unavailable, IAR provides the flexibility to fully secure containers by ensuring that none go unchecked. This enhancement widens the coverage for DevOps teams utilizing image registries, extending CrowdStrike’s robust pre-runtime security capabilities beyond the already supported 16 public registries — the most of any vendor in the market.

IAR is developed for organizations with specific data privacy constraints — for example, those with strict regulations around sharing customer data. Recognizing these challenges, IAR provides a local assessment that enables customers to conduct comprehensive image scans within their own environments. This addresses the critical need for privacy and efficiency by allowing organizations to bypass the limitations of cloud-based scanning solutions, which are unable to conduct scans at the local level.

Further, IAR helps boost operational efficiency at times when customers don’t want to modify or update their CI/CD pipelines to accommodate image assessment capabilities. Its runtime vulnerability scanning enhances container security and eliminates the need for direct integration with an organization’s CI/CD pipeline. This ensures organizations can perform immediate vulnerability assessments as containers start up, examining not only operating system flaws but also package and application-level vulnerabilities. This real-time scanning also enables the creation of an up-to-date software bill of materials (SBOM), a comprehensive inventory of all components along with their security posture. 

A Better Approach to Preventing Non-Compliant Containers and Images

Teams rely on the configuration of access controls within registries to effectively manage permissions for cloud resources. Without proper registry filtering, organizations cannot control who has access to specific data or services within their cloud infrastructure. 

Additionally, developer and security teams often lack the flexibility and visibility to understand where and how to find container images that fall out of security compliance when they have specific requirements like temporary exclusions. These problems can stem from using disparate tools and/or lacking customized rule-making and filtering within their cloud security tools. Security teams then must also be able to relay the relevant remediation steps to developer owners to quickly update the image. These security gaps, if left unchecked, can lead to increased risk and slow down DevSecOps productivity.

To that end, we are also announcing new image assessment policies and registry filters to improve the user experience, accelerate team efficiency and stop breaches. 

These enhancements will address issues by offering:

• Greater control: Enhanced policy exclusion writing tools offer greater control over security policies, allowing organizations to more easily manage access, data and services within their cloud infrastructure while giving the owners of containers and assets the visibility to address areas most critical to them so they can focus on what matters.
• Faster remediation for developers: Using enhanced image assessment policies, developers will be able to more quickly understand why a policy has failed a container image and be able to rapidly address issues before they can pose a greater security risk. 
• Maintain Image Integrity: By creating new policies and rules, security administrators will be able to ensure only secure images are built or deployed.    
• Scalability: As businesses grow and evolve, so do their security needs. CrowdStrike’s customizable cloud policies are designed to scale seamlessly, ensuring security measures remain effective and relevant regardless of organizational size or complexity.

These enhancements are designed to improve container image security, reduce the risks associated with non-compliance, and improve the collaboration and responsiveness of security and developer teams. These changes continue to build on the rapid innovations across Falcon Cloud Security to stop breaches in the cloud.  

Delivered from the AI-native CrowdStrike Falcon Platform

The release of IAR and new policy enhancements are more than just incremental updates — they represent a shift in container security. By integrating security measures throughout the entire lifecycle of a container, from its initial deployment to its active phase in cloud environments, CrowdStrike is not just responding to the needs of the modern DevSecOps landscape but anticipating them, offering a robust, efficient and seamless solution for today’s security challenges. 

Unlike other vendors that may offer disjointed security components, CrowdStrike’s approach integrates elements across the entire cloud infrastructure. From hybrid to multi-cloud environments, everything is managed through a single, intuitive console within the AI-native CrowdStrike Falcon® platform. This unified cloud-native application protection platform (CNAPP) ensures organizations achieve the highest standards of security, effectively shielding against breaches with an industry-leading cloud security solution. The IAR feature, while pivotal, is just one component of this comprehensive CNAPP approach, underscoring CrowdStrike’s commitment to delivering unparalleled security solutions that meet and anticipate the adversaries’ attacks on cloud environments.
