Data Security

RLS/OLS, RBAC/ABAC, PII controls, and key management for enterprise data protection

Overview

Data security encompasses the comprehensive protection of data assets through access controls, encryption, privacy controls, and governance frameworks. It ensures that sensitive information is protected while enabling authorized users to access the data they need for business operations.

This competency covers both preventive security measures and detective controls, implementing defense-in-depth strategies that protect against internal and external threats while maintaining compliance with regulatory requirements.

Access Controls

Implementing granular access control mechanisms that ensure users can only access data appropriate to their role and business needs.

Role-Based Access Control (RBAC)

Hierarchical permission systems based on organizational roles, providing scalable access management through predefined role assignments and inheritance patterns.

Attribute-Based Access Control (ABAC)

Dynamic access decisions based on user attributes, resource properties, environmental conditions, and business context for fine-grained authorization.

Row-Level Security (RLS)

Database-level security that filters data rows based on user identity or group membership, ensuring users only see data they're authorized to access.

Object-Level Security (OLS)

Column and field-level access controls that can mask, encrypt, or completely hide sensitive data elements based on user permissions and data classification.

Privacy & PII Protection

Comprehensive frameworks for protecting personally identifiable information and ensuring compliance with privacy regulations like GDPR, CCPA, and HIPAA.

Data Classification

Automated and manual classification of data based on sensitivity levels, regulatory requirements, and business impact to apply appropriate protection measures.

Data Masking & Anonymization

Dynamic and static data masking techniques that preserve data utility for analytics while protecting individual privacy through tokenization and anonymization.

Consent Management

Systems for tracking and enforcing data subject consent, including purpose limitation, retention policies, and right-to-be-forgotten capabilities.

Cross-Border Data Transfer

Compliance frameworks for international data transfers including adequacy decisions, standard contractual clauses, and data localization requirements.

Encryption & Key Management

Comprehensive encryption strategies that protect data at rest, in transit, and in use while maintaining performance and operational efficiency.

Encryption at Rest

Database-level and storage-level encryption using industry-standard algorithms (AES-256) with proper key rotation and hardware security module integration.

Encryption in Transit

TLS/SSL implementation for all data movement with certificate management, perfect forward secrecy, and protection against man-in-the-middle attacks.

Key Management Systems

Centralized key lifecycle management including generation, distribution, rotation, and destruction using cloud KMS services and hardware security modules.

Application-Level Encryption

Field-level encryption within applications and databases for highly sensitive data elements with separate key management and access controls.

Audit & Monitoring

Comprehensive logging, monitoring, and alerting systems that provide visibility into data access patterns and security events.

Data Access Logging

Detailed audit trails of all data access including user identity, timestamp, data accessed, and business context for compliance and forensic analysis.

Anomaly Detection

Machine learning-based detection of unusual access patterns, data exfiltration attempts, and privilege escalation for proactive security response.

Real-Time Alerting

Automated alerting systems for security violations, policy breaches, and suspicious activities with integration to SIEM and incident response systems.

Compliance Reporting

Automated generation of compliance reports for regulatory requirements including access reviews, data inventory, and security control effectiveness.

Platform-Specific Security

Implementing security controls across diverse technology platforms and cloud services.

Cloud Security

Azure Security

Azure AD integration, Key Vault, Security Center, and Sentinel for comprehensive cloud security across data platforms including Fabric, Synapse, and Power BI.

AWS Security

IAM policies, KMS, CloudTrail, and GuardDuty integration for securing data lakes, warehouses, and analytics services in AWS environments.

Database Security

SQL Server Security

Always Encrypted, Dynamic Data Masking, SQL Audit, and certificate-based authentication for enterprise SQL Server deployments.

Databricks Security

Unity Catalog, table access controls, cluster policies, and secret management for securing big data analytics workloads.

Analytics Platform Security

Power BI Security

RLS implementation, workspace security, app permissions, and data source authentication for enterprise Business Intelligence deployments.
