ORISEN's difference stems from our close relationships with government agencies and our significant investment in IT research and development. We have a management team that understands the intricacies of the federal government, and a staff of subject matter experts who collectively hold more than 25 unique certifications in software development, database administration, networking, and infrastructure. These include Information Technology Infrastructure Library ITIL certification—a comprehensive compilation of best practices and processes for planning, providing, and supporting IT services.

On every systems development program, we use structured, ISO —certified quality management systems to manage all phases of the software development life cycle. E- Governance Get new cohesion and coherence in all of your IT investments.


E-governance—comprising enterprise-wide strategic planning, governance, and IT portfolio management—is the foundation for government agencies making the right IT investments for the best results. Agencies across the government have come to rely on the expert guidance we bring to every phase of the IT life cycle. We conduct strategic assessments and business case analyses to ensure planned technology investments will further agency objectives.

We help agencies turn investment data into meaningful capital planning and improvement information that allows them to allocate resources efficiently and direct their efforts to standardize and consolidate enterprise systems.

And we help put in place performance management processes and measures that ensure that results are delivered on time and on budget and comply with financial performance and regulatory mandates. Nor does compliance with IT security legislation equal true cybersecurity. The contextual layer is at the top and includes business requirements and goals.

The second layer is the conceptual layer, which is the architecture view. The COBIT 5 product family has a lot of documents to choose from, and sometimes it is tough to know exactly where to look for specific information. Applying those principles to any architecture ensures business support, alignment and process optimization. TOGAF is a framework and a set of supporting tools for developing an enterprise architecture. TOGAF is a useful framework for defining the architecture, goals and vision; completing a gap analysis; and monitoring the process. After the architecture and the goals are defined, the TOGAF framework can be used to create the projects and steps, and monitor the implementation of the security architecture to get it to where it should be.

If one looks at these frameworks, the process is quite clear.

This must be a top-down approach—start by looking at the business goals, objectives and vision. The initial steps of a simplified Agile approach to initiate an enterprise security architecture program are:.

Solution architecture

It is that simple. After all risk is identified and assessed, then the enterprise can start designing architecture components, such as policies, user awareness, network, applications and servers. Figure 6 depicts the simplified Agile approach to initiate an enterprise security architecture program. This section describes a simple and practical example of the steps that can be taken to define a security architecture for an enterprise. The enterprise in this example is a financial company, and their goal is to have an additional one million users within the next two years.

Some of the business required attributes are:. All of the controls are automatically justified because they are directly associated with the business attributes. Like any other framework, the enterprise security architecture life cycle needs to be managed properly. It is important to update the business attributes and risk constantly, and define and implement the appropriate controls.

Finally, there must be enough monitoring controls and key performance indicators KPIs in place to measure the maturity of the architecture over time. The CMMI model has five maturity levels, from the initial level to the optimizing level. The aim is to define the desired maturity level, compare the current level with the desired level and create a program to achieve the desired level. This maturity can be identified for a range of controls. Depending on the architecture, it might have more or fewer controls.

Enterprise Architecture and Information Assurance

The outcome of this phase is a maturity rating for any of the controls for current status and desired status. Clinger Cohen Act. E-Government Act of E-Gov Act.
