Section 8 concludes. The Business Attribute Profile can form the basis for all quality requirements (including security requirements) and therefore has significant potential to fully transform the current TOGAF requirements management approach. 3. security architecture and models 1. Security architecture is cost-effective due to the re-use of controls described in the architecture. 1. AVAILABILITY PERFORMANCE SCALABILITY SECURITY MANAGEABILITY The system is continuously operational and able to recover from planned and unplanned outages or disruptions. modeling security as a whole. The SABSA methodology has six layers (five horizontals and one vertical). 1 1 . The main hardware components of a computer system are the CPU, primary and secondary memory, and input/output devices. ���(��y:�B�@F���:\ۘ��;�r�)�1�anA`����9�2;���0���G��v���ӹ�ΚM:����x�)�3Oe΅��k�OU�yj��՚���,�|v�έ�G6g�6[�Q�֦9�@֚�Y�*�����6@%�::8���B0p Q�``� �`l`����| �a���J0R�b�e�cT��Ֆ#���UT�B@�eqƋ�2J�,N��U�d�����``�~ Z�iv ��H{2�Mo����#���mV"8�D��E���A�2�0 ��}� Defendable Architectures are distinguished from traditional security architectures by focusing not just on trying to design a hardened system, but by using threat intelligence and system threat analysis1 to guide architecture decisions, and designing the system to support the needs of Intelligence The system can Secure Systems Research Group - FAU Chromium’s architecture with other browser architectures.

This reference architecture is not just another security book. 4 . The Platform Security Architecture (PSA) is a holistic set of threat models, security analyses, hardware and firmware architecture specifications, and an open source firmware reference implementation. THREAT MODEL In order to characterize the security properties of Chro-mium’s architecture, we de ne a threat model by enumerat-ing the attacker’s abilities and goals. The SA database that contains parameters associated with each active SA. %%EOF A generic list of security architecture layers is as follows: 1. Security Architecture is the design artifacts that describe how the security controls (= security countermeasures) are positioned and how they relate to the overall systems architecture. maintaining a business-driven focus. ; free from fear, care, etc. The OSI model (discussed in Chapter 8, Domain 7: Telecommunications and Network Security) is an example of network layering. Every security solution is based on, and linked to, a business requirement. 9 . 10 . Security architecture calls for its own unique set of skills and competencies of the enterprise and IT architects. h�bbd``b`�$���m@�% H�_7A�ra$آAD�H�� �� m@\+ ��b�d�:��R)&FK ����h�?��w� e 7 Add to cart. Security Architecture for IP (RFC 2401) defines a model with the following two databases: The security policy database that contains the security rules and security services to offer to every IP packet going through a secure gateway.
