Security in the cloud Flashcards
Shared responsibility model
While AWS manages security of the cloud, security in the cloud is responsibility of the customer. Customers retain control of what security they choose to implement to protect their own content, platform, applications, systems and networks, no differently than they would in an on-site datacenter.
AWS WAF
Web Application Firewall
Is a web application firewall that helps protect your web applications from common web exploits that could affect application availability, compromise security, or consume excessive resources.
Operate at level 7
AWS Shield
Is a managed distributed deniel of service (DDoS) protection service that safeguards web applications running on AWS. AWS Shield provides always-on detection and automatic inline mitigations that minimize application downtime and latency, so there is non need to engage AWS Support to benefit from DDoS protection. There are two tiers of AWS Shield - Standard and Advanced.
Amazon Inspector
Is an automated security assessment service that helps improve the security and compliance of applications deployed on AWS. It automatically assesses applications for vulnerabilities or deviations from best practices.
After performing assessment, it produces a detailed list of security findings priortized by level of severity. These findings can be reviewed directly or as part of detailed assessment reports which are available via Amazon Inspector console or API.
