Enterprise Security: A Data-Centric Approach to Securing the Enterprise

By: Aaron Woody

Overview of this book

Enterprise security redefined using a data-centric approach and trust models to transform information security into a business enablement process. It is a unique and forward thinking approach for deciding the best method to secure data in the enterprise, the cloud, and in BYOD environments."Enterprise Security: A Data-Centric Approach to Securing the Enterprise" will guide you through redefining your security architecture to be more affective and turn information security into a business enablement process rather than a roadblock. This book will provide you with the areas where security must focus to ensure end-to-end security throughout the enterprise-supporting enterprise initiatives such as cloud and BYOD. "Enterprise Security: A Data-Centric Approach to Securing the Enterprise" will first introduce the reader to a new security architecture model and then explores the must have security methods and new tools that can used to secure the enterprise.This book will take a data-centric approach to securing the enterprise through the concept of Trust Models and building a layered security implementation focused on data. This is not your traditional security book focused on point solutions and the network aspect of security. This book combines best practice methods with new methods to approach enterprise security and how to remain agile as the enterprise demands more access to data from traditionally untrusted assets, hosted solutions, and third parties. Applied Information Security - A Data-Centric Approach to Securing the Enterprise will provide the reader an easy-to-follow flow from architecture to implementation, diagrams and recommended steps, and resources for further research and solution evaluation.This book is a reference and guide for all levels of enterprise security programs that have realized that non-data centric security is no longer practical and new methods must be used to secure the most critical assets in the enterprise.

Host firewall


The host firewall can be a great method to filter traffic to and from the system. The effectiveness of this control is dependent on the operating system, location of the system, and policy configuration. For example, the implementation of Windows requires several Windows-specific ports and services to be accessible on the internal network to function within the Windows domain that expose services that may be configured in a vulnerable manner. Whereas with Linux, for instance, the host firewall (iptables) can be very effective in protecting the host and the accessible services as there is no concept of a domain. There is functionality within the Windows firewall to limit the accessibility of the Windows services and it can always be configured in an explicit manner limiting access to services.

Implementation considerations

The host firewall cannot be approached as the primary method of securing services on a system. Each service should be configured in a secure manner as the firewall...
