Cloud security services are integrated security solutions and managed operations designed to protect cloud infrastructure, workloads, applications, APIs, and data across: 

• Public cloud environments (AWS, Azure, GCP) 

• Hybrid cloud architectures 

• Multi-cloud deployments 

• Containerized and serverless workloads. 

These services combine cloud-native security tools, automation, policy enforcement, and expert oversight to reduce risk and maintain a strong security posture at scale. 

Cloud Security in the Shared Responsibility Model 

In cloud environments, security responsibilities are divided between the cloud provider and the customer. 

Cloud Provider Responsibilities 

• Physical data center security 

• Underlying hardware and network infrastructure 

• Virtualization layer and cloud fabric security 

Customer Responsibilities 

• Identity and access management (IAM) 

• Network configuration and access controls 

• Operating system and application security 

• Data protection and encryption 

• Monitoring, logging, and compliance 

Most cloud breaches occur within customer-controlled layers, making cloud security services essential. 

Core Technical Domains of Cloud Security Services

Secures the foundational cloud architecture and network boundaries. 

Key capabilities: 

• Secure VPC / VNet architecture and segmentation 

• Network security groups and access control lists 

• Cloud firewalls and Web Application Firewalls (WAF) 

• DDoS mitigation and traffic filtering 

• Zero Trust Network Access (ZTNA) 

Security objective: Reduce attack surface and prevent lateral movement. 

In cloud environments, identity becomes the primary security perimeter. 

Technical focus areas: 

• Least-privilege IAM policies 

• Role-Based Access Control (RBAC) 

• Privileged Access Management (PAM) 

• Multi-Factor Authentication (MFA) 

• Identity federation (SAML, OAuth, OIDC) 

• Continuous identity posture monitoring 

Security objective: Prevent credential compromise and unauthorized access. 

Cloud Workload Protection (CWPP)

Protects workloads running across virtual machines, containers, and Kubernetes. 

Includes: 

• Host-based intrusion detection 

• Container and Kubernetes runtime security 

• Image and workload vulnerability scanning 

• File integrity monitoring 

• Behavioral threat detection 

Security objective: Detect and block malicious activity at runtime. 

Cloud Security Posture Management (CSPM)

Continuously identifies and remediates cloud misconfigurations. 

Technical capabilities: 

• Continuous configuration assessment 

• Policy-as-code enforcement 

• Benchmark mapping (CIS, NIST, ISO, SOC) 

• Automated remediation workflows 

• Drift detection in Infrastructure-as-Code (IaC) 

Security objective: Eliminate misconfigurations, the leading cause of cloud breaches. 

Cloud Data Security & Encryption

Protects sensitive data stored and processed in cloud environments. 

Includes: 

• Encryption at rest and in transit 

• Cloud Key Management Systems (KMS) 

• Customer-managed encryption keys 

• Data Loss Prevention (DLP) 

• Backup and disaster recovery strategies 

Security objective: Maintain confidentiality, integrity, and availability of data. 

Threat Detection, SIEM & Incident Response

Provides centralized visibility and real-time threat detection. 

Key components: 

• Cloud audit logs and telemetry 

• SIEM correlation and alerting 

• Threat intelligence integration 

• User and Entity Behavior Analytics (UEBA) 

• SOAR-driven automated response 

Security objective: Reduce Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR). 

Compliance, Risk & Governance

Aligns cloud security controls with regulatory and industry standards. 

Supported frameworks include: 

• ISO 27001 

• SOC 2 

• HIPAA 

• PCI-DSS 

• GDPR 

• NIST CSF 

Capabilities: 

• Continuous compliance monitoring 

• Audit evidence collection 

• Risk assessment and reporting 

• Cloud governance enforcement
