How Cloud Vulnerability Management Works
CVM systems use a phased approach to assess, prioritize, and remediate vulnerabilities:
- Discovery: Using automated scanning and analysis tools against various data sources, APIs, third-party services, and user-generated content, the CVM system discovers potential vulnerabilities.
- Prioritization: The system assigns each vulnerability a risk score based on factors like severity, impact, and resources affected.
- Assessment: Next, the prioritized vulnerabilities are evaluated and recommendations are made for remediation, including configuration changes, updates or patches to software, disabling unnecessary services, or implementing security controls.
- Remediation: The system may automatically execute recommended actions to address each vulnerability, ensuring the process is swiftly completed.
- Monitoring: CVM systems are designed to continuously monitor the cloud environment for newly-identified vulnerabilities, automatically repeating the detection-remediation cycle.
Common Cloud Vulnerabilities
Vulnerabilities in the cloud originate from many sources, including:
- Cloud Security Risks: Infrastructure as a service (IaaS) platforms, providing access to virtualized computing resources, expose users to risks like unpatched operating systems or misconfigured security groups. Platform as a service (PaaS) environments, which offer pre-built managed services, still present risks in the form of weak authentication controls, insufficient access permissions, or insecure integrations.
- Misconfigurations: Failure to modify default security settings can inadvertently reveal sensitive data. Storage resources exposed to the internet without proper authentication or encryption in place can result in data leakage, while overly permissive user access rights or group membership can result in unauthorized access and data compromise.
- Insecure APIs & Third-Party Services: APIs with weak authentication, inadequate rate limiting, or which lack encryption can enable unauthorized access to resources. Integration of third-party services increases the attack surface and exposes the cloud environment to vulnerabilities in these dependencies.
Proactively addressing these cloud vulnerabilities requires an approach using continuous monitoring, regular audits, and automated remediation.
Developing a Robust Security Strategy: 5 Effective Tips
To create an effective CVM strategy, organizations must consider a number of factors, such as:
- Risk Tolerance: Determine the organization’s risk tolerance and prioritize the allocation of resources by first evaluating the potential threats, vulnerabilities, and impact of a breach.
- Compliance Requirements: Ensure the CVM addresses compliance guidelines that apply to the organization, such as the GDPR or HIPAA regulations, or industry standards like CIS Benchmarks or NIST SP 800-53.
- Shared Responsibility Model: The shared responsibility model asserts that cloud service providers (CSPs) are responsible for physical infrastructure and updates, while their customers are responsible for correctly and securely configuring services to protect sensitive data.
- Clear Responsibilities: Effective collaboration ensures both security and accountability within the organization. Establish clear roles and communication channels between the cloud security team, IT/Operations team, and developers to promote a culture of security.
- Vulnerabilities: Take a risk-focused approach to vulnerability management. Leverage threat intelligence feeds, industry reports, and vendor advisories, and evaluate the likelihood of exploitation and potential damage when developing and implementing remediation strategies.
4 Challenges in Cloud Vulnerability Management
Managing vulnerabilities in the cloud prevents several unique challenges:
- Scalability Issues: Because cloud resources are often transient, with services scaling up and down based on demand, the attack surface is in a constant state of flux. Traditional vulnerability scanners may struggle to keep pace with the churn of short-lived groups and container instances, for example.
- Multi-Cloud and Hybrid IT: Organizations commonly use multiple cloud providers or hybrids of on-premises infrastructure and cloud services. The complexity of these environments often requires substantial effort to maintain security, necessitating the use of multiple vulnerability scanning tools simultaneously.
- Shadow IT: Unapproved use of cloud services by internal business units or individual users makes it difficult to manage vulnerabilities. Employees using personal cloud accounts for work-related tasks further reduce visibility and can also introduce security risks.
- Skills Gap: Cloud services rapidly evolve, with changes to and new functionality outpacing organizations’ ability to keep up. Consequently, the existing skills shortage within security teams grows more severe. Organizations may find it increasingly difficult to find and retain qualified staff to operate CVM systems.
Organizations can enhance their CVM capabilities and better manage risk by acknowledging these challenges and taking steps to proactively manage them.
