Title: Defending and Securing the AWS Cloud

Duration: 4 days (4 hrs each day)

Dates: Dec. 19, 2022 To Dec. 22, 2022

Time: 10 a.m. To 2 p.m. IST

Training Objectives

The rapid adoption of cloud services with ever-growing numbers of AWS services has left the security team with the lion's share of work to identify, analyze and secure an organization's assets across multiple clouds. Multiple cloud accounts and the adoption of "hybrid" cloud environments have added more stress to the whole equation of securing cloud infrastructures. The security team has to cater to the growth and adoption of different services in the cloud and make sure that there is no hole left to get into the infrastructure and do a lateral movement.

Cloud Infrastructure security has multiple pieces including but not limited to, threat modeling the infrastructure, understanding holes in services as they get adopted, writing proactive hardened policies, and making sure that if someone misses a configuration then proactively monitor the configuration and network to enforce security back and do all of this while enabling the business. While infrastructure configuration has to be monitored and secured on a regular basis, hardening OS, CI/CD, containers, and Kubernetes clusters also become an integral part of the security team's realm.
"As many services" is directly proportional to "As many avenues to abuse"!

This training approaches cloud security with a multilayer approach by understanding the perimeter of assets/services, securing cloud-native security services, and getting into the detailed security of every important asset/service/instance.

While cloud-native security solutions are relatively easier to implement and are optimized as per their respective environments, this training doesn't limit the security to native solutions. The training gives an equal amount of open source options to implement a similar or better security posture without depending on cloud-native security services and enables the organization to have more granular control over the security of their infrastructure.
