The TOGAF framework is useful for defining the architecture goals, benefits and vision, and setting up and implementing projects to reach those goals. This maturity can be identified for a range of controls. 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]). What TOGAF says about architecture as description Abstract. In the Enterprise Continuum it describes the concept of a virtual architecture repository containing artifacts and reference models. TOGAF Advanced Enterprise Architecture TOGAF Advanced - Enterprise Architecture.

Figure 8 shows an example of a maturity dashboard for security architecture. Likewise our COBIT® certificates show your understanding and ability to implement the leading global framework for enterprise governance of information and technology (EGIT). While TOGAF 9.1 provides the standard architecture development method (ADM), ArchiMate is the worldwide standard to model and visualize the content of enterprise architectures. 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. Participate in ISACA chapter and online groups to gain new insight and expand your professional influence.
