For many organizations, building a solid information security architecture should be at the top of the list. Read on to learn how what information security architecture is and how it can help you protect your critical IT assets from security threats with less work and worry.

 

What is enterprise information security architecture?

A simple way to define enterprise information security architecture (EISA) is to say it is the subset of enterprise architecture (EA) focused on securing company data.

A more comprehensive definition is that EISA describes an organization’s core security principles and procedures for securing data — including not just and other systems, but also personnel teams and their roles and functions. This information is provided in the context of organizational requirements, priorities, risk tolerance and related factors, to help ensure the EISA reflects both current and future business needs.

Key elements

Here are the key elements of an EISA and the purpose of each:

  • Business context— Defines enterprise information use cases and their importance for reaching business goals.
  • Conceptual layer— Provides the big picture, including the enterprise profile and risk attributes.
  • Logical layer— Defines the logical paths between information, services, processes and application
  • Implementation— Defines how the EISA should be implemented.
  • Solutions— Details the software, devices, processes and other components used to mitigate security vulnerabilities and maintain security for the future.

Benefits of an EISA

Having a solid EISA is invaluable for guiding security planning at all levels. It provides the detailed information required to make the best decisions about what processes and solutions to implement across the IT environment and how to manage the technology lifecycle.

Moreover, a carefully documented and published enterprise information security architecture is vital for compliance with many modern industry standards and legal mandates.

 

The 5 steps to EISA success

The following 5 steps will help you develop an effective EISA:

1. Assess your current security situation.

Identify the security processes and standards your organization is currently operating with. Then analyze where security provisions are lacking for different systems and how they can be improved.

2. Analyze security insights (strategic and technical).

Link the insight gained in step 1 with your business goals. Be sure to include both technical measures and strategy context to prioritize your efforts.

3. Develop the logical security layer of the architecture.

To create a logical architecture for your EISA based on security best practices, use an established framework to assign controls where priority is high.

4. Design the EISA implementation.

Turn the logical layer into an implementable design. Based on your expertise, resources and the state of the market, decide which elements to develop in-house and which things should be managed by a vendor.

5. Treat architecture as an ongoing process.

Since the threat landscape, your IT environment, the solution marketplace and best practice recommendations are all constantly evolving, be sure to review and revise your information security architecture periodically.
