ASPM vs CNAPP – Which Solution To Choose

At first glance it’s hard to tell Application Security Posture Management (ASPM) and Cloud Native Application Protection Platforms (CNAPP) apart, but understanding the nuances between the two is crucial for making informed decisions about your organization’s cloud security strategy.

What is ASPM (Application Security Posture Management)?

ASPM focuses on identifying and managing security risks in applications, particularly in a cloud-native context. ASPMs provide visibility into application security vulnerabilities, configurations, and compliance throughout the software development lifecycle (SDLC). ASPM tools are designed to continuously monitor applications for risks, assess their security posture, and help teams remediate issues effectively.

What is CNAPP (Cloud Native Application Protection Platform)?

CNAPPs follow a broader framework that integrates security throughout the entire cloud-native application lifecycle. They encompass several aspects of security, including vulnerability management, compliance checks, runtime protection, and incident response. CNAPP solutions typically address not only the application layer but also the infrastructure and container orchestration environments, providing a more holistic view of security in cloud-native applications.

Strengths and Weaknesses of ASPM and CNAPP

ASPM Overview

Strengths:

• Focused Application Security: ASPM provides deep insights specifically tailored to application security, helping teams to identify vulnerabilities and misconfigurations effectively.
• Continuous Monitoring: ASPM tools typically offer continuous visibility into application security postures, enabling quicker remediation.
• Integration with DevSecOps: ASPM can easily integrate into CI/CD pipelines, facilitating a shift-left approach to security.

Weaknesses:

• Limited Scope: ASPM primarily focuses on application-level security, which may leave gaps in protecting the underlying infrastructure and environments.
• Reactive Nature: Some ASPM solutions may be more reactive, addressing issues after they arise rather than providing proactive protection measures.

CNAPP Overview

Strengths:

• Comprehensive Coverage: CNAPP addresses security across the entire cloud-native stack, including applications, containers, and serverless functions, offering a more holistic security posture.
• Integrated Workflows: It integrates multiple security functions (like CSPM, CWPP, and more), providing a unified platform for security management.
• Proactive Threat Detection: CNAPP can often employ advanced analytics and machine learning for real-time threat detection and response.

Weaknesses:

• Complexity: The breadth of CNAPP can introduce complexity in deployment and management, which may require specialized skills.
• Cost: Due to their comprehensive nature, CNAPP solutions can be more expensive than standalone ASPM tools, which may not always be justifiable for every organization.

Investment Considerations (or Which One to Choose?)

Why Invest in ASPM?

• If your primary concern is application security and you want to improve your vulnerability management processes within the development lifecycle.
• When your organization is adopting DevSecOps practices and needs a solution that integrates well into CI/CD pipelines.
• If your existing security posture is relatively strong, and you’re looking to enhance specific application security measures.

Why Invest in CNAPP?

• If you are operating in a fully cloud-native environment with complex architectures (e.g., microservices, containers).
• When you require a comprehensive security approach that addresses not just applications but also underlying cloud infrastructure.
• If your organization faces regulatory compliance requirements that demand holistic visibility across environments.

Why Not Invest?

• Budget Constraints: Both ASPM and CNAPP can be significant investments. If budget is limited, focus on foundational security measures first.
• Overlapping Tools: Assess existing security tools in your stack. If your current tools provide adequate coverage for your needs, adding another layer may be redundant.
• Skill Gaps: Consider whether your team has the expertise to effectively implement and manage these solutions. Without the right skills, the investment may not yield desired results.

Where do Non-Human Identities (NHIs) fit in?

What are NHIs?

Non-human identities (a term that encompasses over 1000 types of digital communication including service accounts, cryptographic keys, tokens, APIs, certificates, and more) play a critical role in cloud-native applications.  Cloud applications are composed of microservices and workloads that interact with each other to perform and deliver a service to an end user.  The identities of these interactions as well as the related permissions associated with these identities are referred to as NHIs.

Do CNAPP and ASPMs secure NHIs?

While CNAPP and ASPM technologies secure the platform and infrastructure, upleveling the posture standards of an environment, neither focuses on securing Non-Human Identities – a leading exposure point of cloud applications today.  The inherently transparent interactions of NHIs facilitate access to all sorts of data when compromised, and NHIs are often created with over-permissive scope, reused in multiple places, and rarely retired.  As a result, an NHI that might even be 10 or 20 years old can pose a very real modern threat to current valid data, services, infrastructure, and more.

How do I secure NHIs in my environment?

Securing NHIs requires historical context and understanding of the complete lifecycle of these NHIs.  NHIs can be used throughout an environment in many different ways for many different reasons, and as such they will have different permissive scope and functions.  Securing NHIs involves activities to enhance and secure their creation (segregation of duties, scope restrictions, vault and storage requirements, etc…), restrict their utilization (determining baseline behaviors and identifying abnormal behaviors, monitoring activities, responding in realtime, etc…), and terminate or rotate these identities when they are no longer needed.  Doing all this effectively requires a platform dedicated to non-human identities and contextualization of information from multiple different sources, like that of Entro Security.

Conclusion

Both ASPM and CNAPP play essential roles in modern cloud security strategies along with an NHI security management platform, but they cater to different needs and contexts. Your decision should be based on the specific security challenges your organization faces, your existing security posture, and your long-term strategic goals.
