[Udemy] AWS Certified Data Analytics Specialty - 6.Security
S3 加密
SSE-S3
SSE-KMS
SSE-C
Client Side Encryption
SSL/TLS
S3 支持http/https 两种协议
KMS
KMS最大能加密4KB的数据,再大就要用Evenlope encrption
S3可以做到in-place 加密,其他需要先migration那些数据,需要先backup/snapshot再建加密的数据
没懂Customer-managed CMK 和 AWS managed CMK区别?Customer-managed CMK应该就是上面slide提到的用户自己创建的CMK
automatic key rotation只针对customer-managed CMK!
自动rotation是一年,手动rotation可以自定90,180天等
CloudHSM
AWS的硬件加密器,在AWS机房。我理解就是把KMS的功能放入专门的硬件里了
Kinesis Security
EMR是考试重点, 下面两页PPT要好好看
STS主要用于临时访问AWS资源和cross account 访问
Identity Federation:
接下来重点讲了3种:SAML Federation for Enterprises, Customer Identity Broker appliacation for Enterprises, Cognito
VPC Endpoint, 有两种,Gateway和 Interface(也叫PrivateLink)
Terms:
CMK - Customer Master Key
HSM - Hardware Secutiy Module
