Experience
AWS Well-Architected Framework Audit for a Financial Services Firm
我们实施此审计的方法由AWS良好架构框架(Well-Architected Framework)管理,该框架指导云解决方案架构师在AWS中创建基础设施时采用的最佳实践. The framework consists of six pillars (security, reliability, performance efficiency, cost optimization, operational excellence, and sustainability) that were all thoroughly audited during the engagement. We were granted access to the AWS, the demo, development, and UAT environments. Other documents, such as the AWS billing reports, were provided, as well as answers to questions asked.
The audit identified a total of 46 categorized issues: 11 issues were categorized as high impact, and their potential remediations were shared with the client for action.
Email Server Audit
该项目分三个阶段远程执行,并通过三次前往阿鲁沙总部的区域旅行:
Phase one involved a forensic analysis of the mail system to identify instances of foul play. Malpractice was indeed identified, and the evidence was presented to the project champions.
第二阶段是实现一个解决方案,该解决方案将邮件服务器迁移到安全的云虚拟专用服务器上,并运行加密、电子邮件防病毒和反垃圾邮件机制. This migration was done seamlessly and successfully with minimal business impact.
The final phase was the optimization of office ICT systems for both performance and security. This phase further involved configuration of the mail server to suit organizational needs, such as particular accounts to be limited to internal-only communication.
Overall, the project was a great success.
