Architecting intrusion-detection solutions
Intrusion-detection systems (IDSs) have become an increasingly important part of the
security strategy of many organizations. An IDS plays a key role in the concept of
defense-in-depth, being only one of several deployed countermeasures designed to deter,
slow down, and detect an attack before it occurs or before more serious actions occur.
Discover the different types of IDSs and what types of attacks each can detect (or not
detect), and see issues to consider when planning an IDS deployment.

Predict user mobility in enterprise networks
With the advent of high-speed, high-bandwidth mobile radio technologies
and low-power, high-computing mobile devices, enterprise-application users are
becoming increasingly mobile, rather than remaining fixed or nomadic. To
migrate existing real-time applications of such users to these high-mobility networks,
knowledge of user movement is essential. In the absence of this knowledge,
reestablishing the network-side application context of users can be costly
and lead to performance bottlenecks. In this article, learn about a behavioral
design pattern for mobility prediction in a nomadic, mobile, or an ad-hoc
network. |

The evolving role of the business analyst
Traditionally, the business analyst has been responsible for analyzing the
business needs of companies by identifying business problems and proposing
solutions. With the advent of Service-Oriented Architecture (SOA), the
business analyst has to think about issues such as IT services and how to define
business logic as rules for easier and faster change cycles. Thus, a new
position called the business rules analyst has emerged. This article will
examine the role of this new star in the business world and will also help you
understand how this role can help improve the return on investment (ROI) on
your business applications. |

Increase business agility through BRM systems and SOA
The widespread acceptance of Service-Oriented Architecture (SOA) proves that
enterprises have realized the promise of this technology. That promise of increased
agility comes from a basic software design principle: loose coupling. SOA allows for
business functions to be exposed as independent services. Web services, which is one
way to implement SOA, makes any business functionality available over the Internet.
Another technology that promises to extend that agility to business users is
business rules management (BRM) systems. A BRM system gives business users direct
control over the business logic, allowing them to change it without much
intervention from IT. This article explores how these two technologies--SOA and
BRM--promise to help businesses respond more quickly and cost effectively to
changing market conditions. |

Introduction to business rules
Business rules have existed since companies started automating business
processes using software applications. Traditionally, they have been buried deep
inside the application in some procedural programming language. As business rules
matured, business users tried to control and manage these rules without directly
having to deal with IT, which hasn't always been successful. Using an example from
the insurance industry, this article provides an introduction to business rules and
the importance of Business Rules Management Systems (BRMS) in bridging the gap
between business and IT. |

Modernize legacy systems using an SOA approach
To remain competitive, your organization has to modernize its IT systems.
Modernized IT solutions must create new value from existing systems and provide
flexibility and easy interoperability among a broad set of technologies -- usually a
challenge with legacy applications. Service-Oriented Architecture (SOA), widely
adopted by organizations in recent years, offers a practical solution for evolving
and reusing existing assets. This article shows you a typical approach to
modernizing your legacy systems, including identifying the IT pieces that must be
augmented with new features, determining how the required augmentations are
performed, exposing each capability through a modern interface, and using the newly
exposed services to automate future business processes. |
