What is the Secure code assurance tool
 Secure code assurance tool (SCAT) is a mechanism for implementing a secure software development process SCAT, guided by COBIT, identifies IT risk, assurance, InfoSec, business and developers as being stakeholders in the software development process SCAT is a developer tool that helps development teams meet these stakeholder requirements and generate an audit trail as evidence of a secure development process</li>

What does SCAT do
SCAT is a process integrity tool delivering a consistent, authorised and auditable software development process, proving security controls operate efficiently over a period of time. Preventing vulnerabilities from reaching or recurring in production</li>

What does SCAT not do
SCAT is  not  a point in time security verification tool for  detecting  vulnerabilities in production</li> </ul>

Description
<ul> SCAT is used by inhouse and third party development teams to build, verify and assure secure software

Build
<ul>  SCAT uses code level guidance to clearly instructs developers on how to correctly implement security requirements </li> </ul>

Verify
<ul> SCAT uses a combination of ZAP basic scans and security test plans to verify correct implementation of security requirements</li> </ul>

Assure
<ul> SCAT centrally stores and publishes test results. Providing traceability through requirements and assurance evidence of correct implementation</li> </ul>

SCAT has the following governance objectives implemented by the following “first line of defense” functions

Benefits realisation: Enabling development teams to deliver at speed
 Promoting compliance to security requirements</li> Minimising the impact of audit and assurance</li> </ol>

Risk optimisation: Minimise the negative and maximise the positive consequences
 Informing risk based decision making</li> </ol>

Resource optimisation: Predictable, repeatable and consistent level of security across all teams
 Integrating security into the software development process</li> </ol> SCAT is a simple 5 screen MVC, C# web application with a small footprint that can be deployed without further complicating development environment</li> SCAT is part of three domains to consider when securing software development</li> I've detailed the other domains in an article that will be published in the Nov/Dec issue of the ISC2 magazine, I will add a link here after publication. </ul>

See how developers use SCAT
See below how the Secure code assurance tool integrates security into software development phases <ul>

Sprint planning phase</li>
Objective: Enabling developers to generate security requirements before development begins <ul> <li>Developers use the Identify risks screen to            <ol> <li>Select the critical function to developing/changing</li> <li>Identify the technologies used</li> <li>Automatically generate the security requirements and tests</li> See how to use the tools and its internal mapping to generate security requirements </ol> <li>Product owners use the Secure code requirements screen to            <ol> <li>Create an audit trail to store evidence of secure development</li> <li>Create Jira tickets for requirements and tests to manage work</li> </ol> </li> </ul>

<li>Development phase</li>
Objective: Consistent and correct implementation of security requirements across all teams <ul> <li>Developers use the Secure development screen to            <ol> <li>View and understand how to attack and prevent the risk</li> <li>View the secure code requirements</li> <li>View the secure code block to implement the security requirement</li> <li>Manage development effort in Jira</li> <li>After development run a ZAP basic scan to verify security requirements have been correctly implemented</li> See how the tool helps developers understand security requirements and write secure code </ol> </li> </ul>

<li>Secure code review phase</li>
Objective: Consistent and correct implementation of security requirements <ul> <li>Code reviewers use the Secure code review  screen to            <ol> <li>Guide manually secure code review</li> <li>After manual secure code review run a Sonarqube scan to verify security requirements have been correctly implemented</li> See how the tool verifies correct security requirements implementation </ol> </li> </ul>

<li>Testing phase</li>
Objective: Guide the secure testing process <ul> <li>Testers use the Secure testing screen to            <ol> <li>View the test plans required to test the risk</li> <li>Manage testing effort in Jira</li> See how the tool helps testers test risk mitigation efforts </ol> </li> </ul>

<li>Approval phase</li>
Objective: Streamline the approval and audit process <ul> <li>Approvers use the Assurance evidence  screen to            <ol> <li>View relevant testing evidence alongside the risk, reducing the time assurance teams need to examine and approve releases</li> <li>View verified development effort and whether it falls within risk tolerance levels</li> See how the tool streamlines the approval process with centrally stored testing evidence </ol> </li> </ul>

<li>Risk management</li>
Objective: Enable risk managers to prioritise, plan and monitor mitigation efforts <ul> <li>Risk managers use the Application risk exposure screen to            <ol> <li>View each application critical function and the associated risks</li> <li>Identify where mitigation effort is required by viewing which risks require security requirements</li> <li>Identify where development effort is required by viewing which security requirements need secure code blocks</li> <li>Identify where extra testing effort is required by viewing which risks require security test plans</li> See how the Application landscape overview screen informs risk based decision making </ol> </li> </ul>

Preparation phase
When developing secure software we need to consider both standard secure code and client specific architectural requirements

Standard secure code requirements
<ul> <li>SCAT comes out the box with a standard OWASP secure code requirements map. This mapping need to be modified to the specific organisation requirements</li> <li>Information security and development team use the Internal mapping  screen to           <ol> <li>Map the security requirements to OWASP risks</li> <li>Map organisation approved secure code blocks to security requirements</li> <li>Map security test plans to OWASP risks</li> See how to setup the SCAT's internal mapping </ol> </li> </ul>

Client specific architectural requirements
<ul> <li>To generate these requirements we perform a risk assessment on client application landscape and identify</li> <ol> <li>Critical applications and functions</li> <li>Risk associated with each critical application function</li> <li>Architectural security requirements to secure each critical application functions</li> <li>Client specific secure code blocks to implement security requirements</li> <li>Secure test plans to verify risk has been mitigated</li> </ol> <li>Tool administrators use the Internal mapping  screen to <ol> <li>Create json files of the organisation specific risks, security requirements, secure code blocks and tests</li> <li>Import these into the SCAT</li> See how to import organisations specific risks, security requirements, secure code blocks and tests </ol> </ul>

Promoting compliance to security requirements
<ul> <li>Understand the security requirement: The tool maintains the following internal mapping allowing organisations to translate complex security requirements into code level and testing guidance</li> <ol> <li>Risks mapped to technologies and secure code requirements</li> <li>Secure code requirements (OWASP ASVS) mapped to secure code building block</li> <li>Secure test plans (OWASP testing guide) mapped to risks</li> <li>The second mapping is lifted from OWASP secure knowledge framework and duplicated in the SCAT. I hope to link with the SKF and remove the duplicate functionality from the SCAT tool</li> </ol> <li>Verify understanding: The tool also makes use of OWASP ZAP basic scan to scan localhost for vulnerabilities, confirming the correct implementation of security requirements </li> </ul>

Minimising the impact of audit and assurance
<ul> <li>In the testing and approval phase SCAT allows testers to stores testing evidence against the critical application function and its associated risk. Providing traceability through requirements and centrally storing and publishing test evidence</li> </ul>

Informing risk based decision making
<ul> <li>For each application critical function, SCAT shows</li> <ol> <li>The risks that impact that application critical function</li> <li>Security requirements and secure code block to protect against the risk</li> <li>Test evidence proving risk has been mitigated to within tolerance</li> </ol> <li>Allowing risk teams see levels of exposure, easily compare it to tolerance levels. And prioritise and coordinate mitigation activities across teams and the whole application landscape</li> </ul>

Integrating security into the software development process
<ul> <li>SCAT wraps security theory, best practices and requirements into set of single purpose security screens. Then plots each of those screens to a specific software development phase</li> <li>Plotting security screens to specific software development phases provides development teams with concise information when and how they need it</li> </ul>
