<p>Security Frameworks - Enterprise Architecture Development - Sherwood Applied Business Security Architecture (SABSA)</p>

A 
<p>* It's an Enterprise Security Architecture: Ensures an organization has an effective ISMS in place<br>
* Similar to Zachman<br>
* Views:<br>
- Assets (What)<br>
- Motivation (Why)<br>
- Process (How)<br>
- People (Who)<br>
- Location (Where)<br>
Time (When)<br>
* Y-Axis from wide to narrow<br>
- Contextual<br>
- Conceptual<br>
- Logical<br>
- Physical<br>
- Component<br>
- Operational<br>
* Difference between SABSA and the others<br>
- It is also a methodology<br>
- Provides an actual process to follow<br>
- It is geared toward security</p>

Q

<p>Security Frameworks - Architecture Framework Terms</p>

A

<p>* Strategic Alignment: An architecture is strategically aligned when it meets the needs of the business and all legal or regulatory requirements<br></br>

* Business Enablement: A good security architecture must enable the business to thrive by not getting in the way, but still providing proper security<br></br>
* Process Enhancement: Security forces us to take a closer look at existing processes. This could lead us to improve them<br></br>
* Security Effectiveness: Most quantifiable of the attributes. Examples: ROI, SLA achievements</p>

112
Q

<p>Assessing and Analyzing Risk - Identifying Vulnerabilities and Threats</p>

A

<p>* Threats can arise from seemingly innocuous sources such as our own applications and users<br></br>
Examples:<br></br>
- An application could have a logic flaw, known as illogical processing, which destroys or compromises data or resources. This can then lead to cascading errors wherein a small flaw is passed to another process, which can amplify the flaw<br></br>
- A user can enter invalid data or even accidently delete important data<br></br>
* Loss Potential:Each risk has it<br></br>
* Delayed Loss: It happens after the vulnerability has been exploited. Example: Your company's reputation takes a hit</p>
