As the world continues to migrate to the cloud and data breaches make headlines regularly, it has become paramount for organizations to ensure their cloud infrastructure — and the sensitive data within — remain secure.
In this blog, we’ll explore the essential roles of data security posture management (DSPM) solutions and cloud security posture management (CSPM) solutions and discuss how Varonis uniquely applies both within our platform, enabling you to bridge the gap between cloud and data security.
While both solution types are designed to protect your organization from cyber threats, they each take a unique approach to achieving that goal.
DSPM and CSPM — how do they differ?
DSPM ensures that sensitive data is protected wherever it resides, while CSPM focuses on securing the cloud infrastructure that critical business applications are built and hosted on.
DSPM is designed to protect sensitive data and ensure compliance with regulations across various environments, including SaaS, cloud-based, and on-premises platforms.
The primary objective of DSPM is to ensure the security and compliance of data, regardless of where it resides. DSPM implements comprehensive measures such as data discovery, classification, access controls, and continuous monitoring.
On the other hand, CSPM is all about protecting your cloud infrastructure by taking a vulnerability-centric approach. CSPM scans and analyzes cloud infrastructure to identify misconfigurations and other security gaps in the environment. It assigns risk scores to prioritize remediation efforts and continuously monitors the environment for emerging threats.
By focusing on vulnerabilities, CSPM helps organizations automate patching processes, ensure compliance, adapt to evolving threats, and proactively reduce the risk of exploitation. These tools are crucial for maintaining a strong security posture in dynamic cloud environments.
Core functions of DSPM
DSPM provides organizations with the tools and capabilities needed to identify, assess, monitor, and protect sensitive data throughout its lifecycle. This helps organizations understand where sensitive data is located, who has access to it, how it is being used, and whether it is adequately protected.
The core components of DSPM typically include:
- Data discovery and classification: DSPM automates scanning and discovery techniques to locate sensitive data wherever it resides and categorize the data based on its sensitivity and type, allowing organizations to prioritize security measures and better manage compliance efforts.
- Data access governance: DSPM maps permissions across the data estate and enables organizations to define and enforce access policies and permissions that ensure only authorized individuals can access sensitive data. DSPM also provides automated remediation of permissions to reduce data exposure and achieve a least privilege model.
- Data Risk Assessment: DSPM assesses data security risks by evaluating factors such as data exposure, vulnerabilities, and compliance with data protection regulations. These tools provide risk levels and recommendations for remediation.
- Compliance reporting and auditing: DSPM generates compliance reports and audit logs to help organizations stay compliant with various regulatory frameworks, such as GDPR, HIPAA, or CCPA. These reports are essential for regulatory audits and internal governance.
- Activity monitoring and threat detection: DSPM monitors data to identify unusual or suspicious activity like excessive or unauthorized access, encryption, and potential exfiltration. This helps organizations detect insider threats, ransomware, and advanced persistent threats.
- Incident response and remediation: DSPM provides incident response capabilities to address security incidents and data breaches quickly. These tools may automate response actions, such as removing access or shutting down affected systems and user sessions.
By implementing these core components across your ecosystem, a DSPM approach empowers businesses to identify and reduce data risk, maintain compliance, and mitigate the risk and impact of breaches.
Core functions of CSPM
A CSPM strategy helps organizations proactively reduce the risk of exploitation, automate remediation processes, ensure compliance, and adapt to evolving threats. This approach is crucial for maintaining a strong security posture in dynamic cloud environments.
The core components of CSPM typically include:
- Asset discovery: CSPM automatically discovers and inventory all assets within an organization's cloud environment. This includes virtual machines, storage buckets, databases, network configurations, and more. Accurate asset discovery is crucial for assessing the security of cloud resources.
- Configuration management: CSPM evaluates the security configurations of cloud assets against industry best practices and compliance standards, such as CIS benchmarks or cloud-specific security guidelines. This approach identifies misconfigurations that could expose assets to vulnerabilities or unauthorized access and provides the necessary steps for remediation.
- Vulnerability assessment: CSPM performs regular vulnerability scans of cloud resources to detect known weaknesses. These solutions provide organizations with vulnerability scores and can prioritize remediation efforts based on the severity of the issues.
- Remediation and reporting: CSPM provides guidance and recommendations for remediation of identified security issues. These solutions offer reports and dashboards to help organizations track their security posture over time and demonstrate compliance to auditors. Certain solutions even provide automated remediation capabilities.
- Network security assessment: CSPM evaluates network security controls, including firewall rules, network segmentation, and traffic monitoring, to detect any potential security gaps or misconfigurations in the cloud network infrastructure.
- Compliance monitoring: CSPM continuously monitors cloud resources for compliance with industry-specific regulations and standards, such as GDPR, HIPAA, or SOC 2. It generates compliance reports and alerts organizations when non-compliance is detected through configuration drift.
- Threat detection and response: Some CSPM solutions offer threat detection capabilities by analyzing cloud logs and network traffic patterns to identify suspicious activities or potential security incidents. These solutions may also provide automated response actions.
CSPM is essential for organizations adopting cloud services to ensure that their cloud environments are secure, compliant, and resilient to threats. This approach helps organizations proactively manage security risks and maintain a strong security posture as they leverage cloud technologies for their business operations.
DSPM and CSPM — Two pieces of a complete cloud security strategy
The complexities of securing both cloud environments and the data within underscore the need for a security strategy that implements both DSPM and CSPM solutions, ensuring they work hand in hand.
DSPM solutions enable organizations to monitor and protect sensitive data wherever it resides, while CSPM focuses on securing the cloud infrastructure itself and closing the pathways to the data within. These two solutions complement each other, providing comprehensive security coverage in an era where cyber threats are constantly evolving.
Unified visibility
Together, DSPM and CSPM solutions can provide a holistic view of an organization's entire security landscape, including both data and cloud assets. By integrating data discovery and asset discovery, organizations gain a unified understanding of where their sensitive data resides and how it is stored, accessed, and protected within their cloud environments.
Configuration and exposure management
CSPM solutions can help identify misconfigurations or vulnerabilities within cloud environments that may expose sensitive data to security risks. When such risks are identified, DSPM solutions can determine if sensitive data is at risk and provide insights into its exposure, thereby enabling timely remediation.
Compliance management
Both DSPM and CSPM are instrumental in ensuring compliance with regulatory standards and security best practices. These strategies work together to monitor and enforce compliance policies across data and cloud assets, providing a comprehensive approach to compliance management to help reduce the risks of penalties and fines.
Incident response
In the event of a security incident in the cloud, CSPM can quickly detect the breach and initiate response actions. Simultaneously, DSPM can detect if sensitive data has been compromised and provide the tools and guidance needed to investigate and contain the breach, mitigate risks, and report any potential data leaks.
Security automation
Integrating DSPM and CSPM solutions can facilitate automated responses to identified security issues. When vulnerabilities or misconfigurations are detected in the cloud environment, automated actions can be initiated to minimize potential data exposure.
Enhanced reporting and auditing
Organizations can use DSPM and CSPM to generate comprehensive reports that not only demonstrate compliance with data protection regulations but also provide insights into the security of data and cloud resources. This reporting can be crucial for internal governance and regulatory audits.
By integrating CSPM and DSPM solutions, organizations create a unified security strategy that bridges the gap between data and cloud security, offering a comprehensive approach to protecting sensitive data in an increasingly cloud-centric world. This collaboration ensures that data remains secure and compliant, regardless of where it's stored or how it's accessed.
