- Data Analytics: Protect sensitive data used for analytics by encrypting data at rest and in transit, implementing access controls, and monitoring for unauthorized access. Consider using Data Masking techniques for sensitive information.
- DevOps Pipelines: Integrate security into your DevOps pipelines by automating security testing, vulnerability scanning, and compliance checks. Utilize Azure DevOps security features.
- Disaster Recovery: Ensure the security of your disaster recovery environment by replicating security configurations and implementing appropriate access controls.
- Hybrid Cloud Environments: Extend your on-premises security policies to Azure using Azure Arc and consistent identity management.
- Dedicated **Server** Workloads: Even when utilizing a dedicated **server** within Azure, these principles of least privilege, encryption, and monitoring still apply.
Performance
Security measures can sometimes impact performance. However, with careful planning and optimization, the performance impact can be minimized. Here’s a breakdown of potential impacts and mitigations:
| Security Feature | Potential Performance Impact | Mitigation Strategy |
|---|---|---|
| Encryption | Increased CPU usage during encryption/decryption. | Utilize hardware-accelerated encryption where possible. Choose appropriate encryption algorithms. |
| Network Security Groups (NSGs) | Increased latency due to rule evaluation. | Optimize NSG rules for efficiency. Minimize the number of rules. Use service tags. |
| Web Application Firewall (WAF) | Increased latency due to traffic inspection. | Tune WAF rules to minimize false positives and unnecessary processing. |
| Multi-Factor Authentication (MFA) | Slight increase in login time. | Optimize MFA configuration and user experience. |
| Azure Security Center Scanning | Resource utilization during scans. | Schedule scans during off-peak hours. |
Regular performance monitoring is crucial to identify and address any performance bottlenecks introduced by security measures. Tools like Azure Monitor can help track performance metrics and identify areas for optimization. Proper selection of SSD Storage can also help mitigate performance impacts related to encryption.
