Whether an organization is small with a relatively straightforward data environment or a larger entity with a data infrastructure that's far-reaching and complex, it's a good idea to identify and protect against security risks by establishing a security architecture program and the associated processes to implement it. 267 Chapter 9 Endpoint Anti-malware Let’s now leave the world of Digital Diskus and turn to a set of architectural problems that is different from securing enterprise architectures. Descriptions of how security can be modeled in DoDAF using structured and object oriented techniques are presented, how it is modeling in other frameworks and how the use of Colored Petri-Nets can be a potential candidate for security architectures. 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 Integration: Easier to build secure processes with other companies and trusted partners. endstream endobj 171 0 obj <>/Metadata 78 0 R/Outlines 111 0 R/Pages 164 0 R/StructTreeRoot 121 0 R/Type/Catalog>> endobj 172 0 obj <>/Font<>/ProcSet[/PDF/Text]/Properties<>>>/Rotate 0/StructParents 0/TrimBox[0.0 0.0 504.0 720.0]/Type/Page>> endobj 173 0 obj <>stream The main hardware components of a computer system are the CPU, primary and secondary memory, and input/output devices.
