Todays Imperative is Information-Centric Security
Controlling Information Flow
Information Management Magazine, May 2008
For more than 20 years, enterprises have clung to the idea of securing operating systems, networks, storage, communication channels and all the hardware they run on. These investments protected the computing equipment, which is now relatively cheap and easily replaced. The theory went that by securing the equipment and entry points within the enterprise, the information residing therein was safe and secure. Advertisement Todays global business enterprises demand a framework that ensures their IT systems information security addresses the current realities of enterprise, network and information sharing and access. Globalization, service orientation and outsourcing have changed the requirements from those of the last two decades. Global businesses demand secure IT operations over open networks (i.e., the Internet) so they can share information in a controlled way with their business partners and customers. Information services providers derive their business value from their ability to maintain asymmetric differences in information availability. For some enterprises competing in the information age, managing information scarcity or flow is their only business advantage - the only thing worth preserving. Because the information is what is valuable now, we need to focus on its protection. Information-centric security is the new goal, and accomplishing that goal will require improvements in information security governance and architecture. Governing Information-Centric Security Todays globally connected enterprises require information services that are: These information services are also viewed by a broad range of stakeholders as safe, secure and compliant to applicable regulations and audit practices. Accomplishing a widely held consensus of safety, security and compliance requires a governance team and process that represent the viewpoints of all the business stakeholders and that involve and reconcile the often competing and conflicting objectives from each community of interest to arrive at appropriate solutions. The stakeholders from the IT technology side - security architects, IT technologists, user interface designers - need to work more closely now than ever before with corporate legal counsel, corporate policy-makers, risk management decision-makers, auditors and business managers throughout the systems development lifecycle. They also need to include requirements from outside the enterprise that may conflict with immediate enterprise business objectives, including those driven by public interest groups and government, because these communities are developing new standards of performance and regulations that place controls on information and the acceptable use of information systems. In short, good information-centric security governance requires resolving tensions between competing public sector, business sector and consumer interests, which can be defined as the following: While functional responsibilities and organizations will likely persist in any medium to large enterprise, resolving these tensions requires improvements in a cross-functional collaboration to develop a dynamic, process-oriented, information-centric security governance framework that ensures the right business decisions are made to arrive at the best solutions for that enterprise. The Open Groups Security Forum and the American Bar Associations Cyberspace Law Committee are pioneers in this necessary cross-profession collaboration, in analyzing and recommending improvement to current, perimeter-based and proprietary-based enterprise-level information security practices. The groups are proposing a new framework for effective information-centric security, starting with the desire to control information flow inside and beyond the border of the business. Information-Centric Security Starts with Control Previous work of The Open Groups Security Forum and the Cyberspace Law Committee has already recognized that the control of intangible electronic assets - i.e., information - is a functional equivalent for possession of physical assets in the physical world.1, 2 By extending the example of this work here, information-centric security becomes a question of maintaining the equivalency of ownership through control over information assets wherever they are. To this end, four key principles of control emerge: Extending Control Beyond the Enterprises Perimeter Control beyond the enterprises environment is challenging because of two considerations: Compliance Managing people, processes and technologies outside of ones direct control has strong parallels with the general problem of compliance to external standards, regulations or policy. A generalized compliance model works such that if the corporate policy complies with the external requirements, legal and otherwise, and if the IT operation complies with policy, then the IT operation complies with the external requirements. There are six major compliance activities: Extending compliance beyond your enterprise is usually established through formal agreements, such as a contract or SLA, and monitoring to verify the terms of the SLA are being met. Establishing SLAs is a business management and legal process, and verifying compliance to an SLA usually includes monitoring and reporting on system performance metrics. Whether described as deperimeterization, information-centric security or a framework for control of electronic assets, the information security governance team must consider economic, policy and technical factors impacting the security architecture and represent all the different views needed to sustain all of the stakeholders in the process. Security as a combination of people, processes and technologies is nowhere more evident than in the control of information across enterprise perimeters. Corporate legal, corporate policy and internal audit are now among the key stakeholders in a corporations security architecture. The needs of these stakeholders in the past have not been well articulated within the IT architecture community, but they need to be. Helping these new stakeholders better understand the processes and technologies used to implement policies is essential to making the compliance framework work. Cross-functional information security governance resolves the needs and tensions between these stakeholders, and security architects can take a lead role in facilitating this dialog between the different stakeholder viewpoints.
