What is CNAPP?
CNAPP is a class of security technology focused on protecting dynamic cloud-native applications and their underlying infrastructure. It combines various security functionalities, reducing operational complexity and costs while providing comprehensive protection against evolving threats.
Main Capabilities
- Agentless Operation: CNAPP solutions continuously monitor and identify misconfigurations in cloud resources without use of agents. This ensures low impact on application performance.
- Cloud-Native Attack Detection: By analyzing network traffic and user behavior across the infrastructure, platform, and application, CNAPP can detect attacks tailored to cloud-native environments.
- Reduced Complexity and Costs: CNAPP consolidates security capabilities like intrusion detection, vulnerability assessment, and cloud security posture management (CSPM). This simplifies security operations and reduces the need for multiple solutions.
- Broad Threat Coverage: Because CNAPP addresses a wide range of threats, including unauthorized access, API attacks, and container vulnerabilities, it provides comprehensive protection against cloud-specific risks.
How it Works
CNAPP is based on continuous monitoring and advanced algorithms enhanced by machine learning and artificial intelligence. These capabilities enable security staff to identify and mitigate security risks in real-time. CNAPP offers deep visibility into cloud infrastructure, allowing for automated remediation and easy integration with other security tools.
CNAPP is a cloud risk management approach designed for cloud-native applications to address their unique challenges.
What is CWPP?
CWPP is an established security solution that focuses on safeguarding traditional workloads and infrastructure-as-a-service (IaaS) cloud environments. It offers a range of capabilities to continuously monitor, detect, and mitigate threats targeting cloud resources.
Main Capabilities
- Continuous Monitoring: CWPP solutions regularly assess cloud resources for potential security weaknesses and malicious activities, enabling proactive threat identification and remediation.
- Intrusion Detection and Prevention (IDP): CWPP offers real-time IDP capabilities to identify and block attacks targeting the network and cloud workloads. It uses advanced detection techniques to protect against both known and unknown threats.
- Data Loss Prevention (DLP): CWPP incorporates DLP features to prevent unauthorized access or transmission of sensitive data from the cloud environment. By monitoring inbound and outbound data and enforcing security policies, CWPP helps organizations maintain data privacy and comply with regulatory requirements.
- Vulnerability Assessment: CWPP solutions scan cloud workloads for vulnerabilities and provide automated patch management to mitigate the risks identified, helping systems remain secure and up-to-date against emerging threats.
How it Works
CWPP is commonly, though not always, deployed using an agent within the cloud environment. Agent-based solutions may be deployed directly on workloads, while agentless solutions may operate as a lightweight virtual appliance. CWPP continuously monitors network traffic, system logs, and user activity for signs of compromise or misconfiguration. The system relies on signature-based and/or behavior-based detection methods to identify and block threats.
CWPP offers continuous monitoring, IDP, DLP, vulnerability assessment, and patch management, allowing organizations to solidify the security posture of their cloud infrastructure.
CNAPP vs. CWPP: In-Depth Comparison
Both CNAPP and CWPP offer unique benefits, but also have significant differences:
Focus and Objectives
- CNAPP: Designed to address the security challenges of cloud-native applications. It focuses on protecting containers, serverless functions, microservices, and other cloud resources.
- CWPP: Targeted at securing traditional workloads, virtual machines (VMs), and cloud-based IaaS resources like compute instances and storage services.
Scope of Protection
- CNAPP: Protects the entire cloud-native stack, offering security for containers, serverless architectures, and microservices. Provides deep visibility into application-layer threats and vulnerabilities.
- CWPP: Primarily focuses on network-based attacks, system-level vulnerabilities, and unauthorized access.
Deployment Strategies
- CNAPP: Agentless solution for easy deployment in dynamic cloud-native environments. Optimal for continuous integration and continuous deployment (CI/CD) pipelines and microservices architectures.
- CWPP: Commonly uses agents or lightweight virtual appliances, introducing overhead and complexity in managing deployments, and may not be suitable for all workloads.
Integration with Existing Systems
- Both: CNAPP and CWPP present APIs and integration options to connect with other security tools, such as Security Information and Event Management (SIEM) systems.
- CNAPP: Strong integration with CI/CD pipelines and DevOps tools due to its focus on cloud-native applications. This enables automated security testing and enforcement throughout the software development lifecycle (SDLC).
Compliance and Regulations
- Both: CNAPP and CWPP provide reports and dashboards to facilitate compliance audits.
- CNAPP: Offers more tailored compliance reports for cloud-native regulations, such as NIST SP 800-53 and CIS Benchmarks.
Monitoring and Reporting
- Both: Both CNAPP and CWPP offer real-time monitoring, alerts, and customizable reports.
- CNAPP: Provides reports covering a broad spectrum of cloud capabilities, offering deeper insights into application threats and vulnerabilities.
Cost Considerations
- Both: Both CNAPP and CWPP offer competitive pricing with subscription-based models.
- CNAPP: Potential long-term cost savings due to its unified security approach. Since it addresses security across the entire cloud-native stack, CNAPP can help reduce the need for multiple layers of narrowly-scoped security solutions.
Which One to Choose?
Selecting between CNAPP and CWPP involves careful consideration of the organization’s unique needs:
Cloud Maturity and Workload Types
CNAPP:
- Mature cloud adoption, with a significant portion of cloud-native or microservices workloads.
- A heavy focus on DevOps and CI/CD pipelines for application deployment and management.
- A need to address application-layer cloud security challenges.
CWPP:
- Mostly traditional workloads, like virtual machines and on-premises applications migrating to the cloud.
- Less cloud adoption, with most resources still hosted on platforms like VMs or bare-metal instances.
- Defending against network-based threats, system-level vulnerabilities, and infrastructure security.
Unified vs Siloed Approach
CNAPP:
- If the organization needs a unified security platform to address security across the entire cloud-native stack.
- This approach supports breaking down silos between different teams and streamlining workflows.
CWPP:
- If the organization prefers a siloed approach to security, with separate tools for application and infrastructure security.
- More suitable for organizations with rigid, established processes and dedicated teams for specific aspects of security.
Available Resources
- Assess all resources required for implementation and management when choosing between CNAPP and CWPP.
- Given employee skill sets, evaluate the practicality of the organization handling a unified approach (CNAPP) or if a siloed approach (CWPP) would be more feasible.
- Consider long-term administration requirements, such as ongoing maintenance and updates for the chosen solution.
While both options have clear merits, the ideal choice ultimately depends on the organization’s specific context, including security posture, staff readiness, and cloud adoption maturity.
