Enterprise Cloud Security and Governance

By: Zeal Vora

Overview of this book

Modern day businesses and enterprises are moving to the Cloud, to improve efficiency and speed, achieve flexibility and cost effectiveness, and for on-demand Cloud services. However, enterprise Cloud security remains a major concern because migrating to the public Cloud requires transferring some control over organizational assets to the Cloud provider. There are chances these assets can be mismanaged and therefore, as a Cloud security professional, you need to be armed with techniques to help businesses minimize the risks and misuse of business data. The book starts with the basics of Cloud security and offers an understanding of various policies, governance, and compliance challenges in Cloud. This helps you build a strong foundation before you dive deep into understanding what it takes to design a secured network infrastructure and a well-architected application using various security services in the Cloud environment. Automating security tasks, such as Server Hardening with Ansible, and other automation services, such as Monit, will monitor other security daemons and take the necessary action in case these security daemons are stopped maliciously. In short, this book has everything you need to secure your Cloud environment with. It is your ticket to obtain industry-adopted best practices for developing a secure, highly available, and fault-tolerant architecture for organizations.

In an asymmetric key encryption, there are two keys involved. These are referred to as public key and private key.

The magic in this is that the message encrypted by one of the keys can only be decrypted by the other associated key. This means that the message encrypted by the public key can only be decrypted by the corresponding private key and the message encrypted by the private key can only be decrypted by the corresponding public key.

Ideally, as the name suggests, the public key is supposed to be shared with everyone, while the private key is meant to be secret.
