Architecture Layers . It was released as a reference model for enterprise architecture, offering insight into DoD’s own technical infrastructure, including how it’s structured, maintained and configured to align with specific requirements. For more on this subject, see 'Topic 5 - Security Architecture'. Finally, there must be enough monitoring controls and key performance indicators (KPIs) in place to measure the maturity of the architecture over time. 2. 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. The first phase measures the current maturity of required controls in the environment using the Capability Maturity Model Integration (CMMI) model. The Architecture Continuum assets will be used to guide and select the elements in the Solutions Continuum (see below). Some of the business required attributes are: All of the controls are automatically justified because they are directly associated with the business attributes. After all risk is identified and assessed, then the enterprise can start designing architecture components, such as policies, user awareness, network, applications and servers. TOGAF Technical Reference Model. The Open Group Architecture Framework or TOGAF has been developed by more than 300 enterprise architects from leading companies including Dell, Cognizant, and Microsoft. The earliest rudiments of the step-wise planning methodology currently advocated by TOGAF and other EA frameworks can be traced back to the article of Marshall K. Evans and Lou R. Hague titled "Master Plan for Information Systems" published in 1962 in Harvard Business Review. TOGAF is a management framework that features and promotes the role of architects. Scott Bernard visualizesEA as meta-discipline that covers entire organization, “EA is, therefore, THE architecture of the enterprise and should cover all elements and aspects. TOGAF provides the methods and tools for assisting in the acceptance, production, use, and maintenance of an enterprise architecture. Validate your expertise and experience.

In the Enterprise Continuum it describes the concept of a virtual architecture repository containing artifacts and reference models. 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. Your architecture organization will have to deal with each type of architecture described above. By using a combination of the SABSA frameworks and COBIT principles, enablers and processes, a top-down architecture can be defined for every category in figure 2. TOGAF is a management framework that features and promotes the role of architects. Since 1999, the DoD hasn’t used the TAFIM, and it’s been eliminated from all process documentation.

Following a framework will give a team launching EA as a new practice a way to assemble and organize a cohesive set of models for use across the enterprise. § The Resource Base is a set of ‘good practice’ resources such as guidelines, checklists and templates provided to assist the architect when using TOGAF ADM. As shown in the figure, TOGAF divides an enterprise architecture into four categories, as follows: Business architecture—Describes the processes the business uses to meet its goals; Application architecture—Describes how specific applications are designed and how they interact with each other; Distributed denial of service (DDoS), firewall, intrusion prevention system (IPS), VPN, web, email, wireless, DLP, etc. Sparx Systems Community for Enterprise Architect Users: News, Tutorials, Resources, White Papers & Case Studies. The goal of the COBIT 5 framework is to “create optimal value from IT by maintaining a balance between realising benefits and optimising risk levels and resource use.” COBIT 5 aligns IT with business while providing governance around it. DataInformation_architecture_layer. TOGAF, in the ADM and the various guidelines and techniques, provides a process for developing architecture. As EA teams move forward, though, they may adjust the framework or structure to fit their organization or culture as needed. Architecture layers. Define component architecture and map with physical architecture: Security standards (e.g., US National Institute of Standards and Technology [NIST], ISO), Security products and tools (e.g., antivirus [AV], virtual private network [VPN], firewall, wireless security, vulnerability scanner), Web services security (e.g., HTTP/HTTPS protocol, application program interface [API], web application firewall [WAF]), Not having a proper disaster recovery plan for applications (this is linked to the availability attribute), Vulnerability in applications (this is linked to the privacy and accuracy attributes), Lack of segregation of duties (SoD) (this is linked to the privacy attribute), Not Payment Card Industry Data Security Standard (PCI DSS) compliant (this is linked to the regulated attribute), Build a disaster recovery environment for the applications (included in COBIT DSS04 processes), Implement vulnerability management program and application firewalls (included in COBIT DSS05 processes), Implement public key infrastructure (PKI) and encryption controls (included in COBIT DSS05 processes), Implement SoD for the areas needed (included in COBIT DSS05 processes), Application security platform (web application firewall [WAF], SIEM, advanced persistent threat [APT] security), Data security platform (encryption, email, database activity monitoring [DAM], data loss prevention [DLP]), Access management (identity management [IDM], single sign-on [SSO]), Host security (AV, host intrusion prevention system [HIPS], patch management, configuration and vulnerability management), Mobile security (bring your own device [BYOD], mobile device management [MDM], network access control [NAC]), Authentication (authentication, authorization, and accounting [AAA], two factor, privileged identity management [PIM]). Harvard University’s vision for enterprise architecture is to articulate and drive to common solutions, standards, and opportunities for alignment in order to reduce IT complexity and cost across the University and enable local innovation. The TOGAF framework goes on to describe the ‘contents’ within each in terms of ‘content metadata’, with relationships between all the pieces and parts. Published: 2017-12-04 Layering is a core technique in enterprise architecture. § The Enterprise Continuum is a model for structuring a ‘virtual repository’ of architectural assets such as patterns, models, & architecture descriptions.
