AWS Security Cookbook

By: Heartin Kanikathottu

Overview of this book

As a security consultant, securing your infrastructure by implementing policies and following best practices is critical. This cookbook discusses practical solutions to the most common problems related to safeguarding infrastructure, covering services and features within AWS that can help you implement security models such as the CIA triad (confidentiality, integrity, and availability), and the AAA triad (authentication, authorization, and availability), along with non-repudiation. The book begins with IAM and S3 policies and later gets you up to speed with data security, application security, monitoring, and compliance. This includes everything from using firewalls and load balancers to secure endpoints, to leveraging Cognito for managing users and authentication. Over the course of this book, you'll learn to use AWS security services such as Config for monitoring, as well as maintain compliance with GuardDuty, Macie, and Inspector. Finally, the book covers cloud security best practices and demonstrates how you can integrate additional security services such as Glacier Vault Lock and Security Hub to further strengthen your infrastructure. By the end of this book, you'll be well versed in the techniques required for securing AWS deployments, along with having the knowledge to prepare for the AWS Certified Security – Specialty certification.

Web Security Using ELBs, CloudFront, and WAF

Load balancers distribute the load across different systems. They help us handle loads effectively to achieve reliability and high availability. Load balancers can terminate TLS at the load balancer level and provide us with a single place to manage the X.509 certificates that are required. They can also perform TCP passthrough for the TLS traffic and let TLS terminate at the instance level. Firewalls are important security mechanisms that protect networks and systems by monitoring and controlling incoming and outgoing traffic. In this chapter, we will learn about various ways in which we can implement load balancers and firewalls within AWS.

This chapter will cover the following recipes:

  • Enabling HTTPS on an EC2 instance
  • Creating an SSL/TLS certificate with ACM
  • Creating a classic load balancer
  • Creating ELB target groups
  • Using an application...
