Computer security is the all encompassing term given to the field of information technology that deals with securing the virtual environments that power the digital age. This can include data protection and integrity, application security, risk and vulnerability assessment and authentication and authorization protocols.
Computer data is an all important asset for most organizations. Data protection is vital and forms the core of most businesses. JBoss EAP 6 provides a multi-layered approach to security to take care of data at all stages.
Truly secure systems are the ones that are designed from the ground up with security as the main feature. Such systems use the principle of Security by Design. In such systems, malicious attacks and infiltration's are accepted as part and parcel of normal security apparatus and systems are designed to work around them.
Security can be applied at the operating system, middleware and application level. For more information about security at the operating system level as it applies to RHEL, refer to the Red Hat Enterprise Linux Security Guide.
In the coming chapters, you will read about the different levels and layers of security within JBoss EAP 6. These layers provides the infrastructure for all security functionality within the platform.
