4. Benefits Summary

1. Companies are responsible for their own custom code.

2. If you can’t enforce code quality and security standards consistently, it won’t work.

How ABAP code reviews are often done today:

• Manual code reviews

• Using top programming resources for reviews

• Using basic tools with limited testing and lot of false-positive findings

• No effective technical code testing at all!

Today‘s Practices?

Manual Code Reviews:– Use valuable development resources– Delay project release (or accept lower quality)– Limited effectiveness due to program complexity – Feedback too late in development cycle

• Performance/Failures in production • Higher cost of mediation

– Few/No defined security & quality standards• Styles and techniques vary by reviewer/developer


Basic ABAP Testing Tools:– Limited (and weak) testing, e.g. pattern recognition– Not comprehensive for Security and Quality– Not integrated with ABAP Development Workbench

• No on‐line scanning during development• Higher TCO for manual corrections • No documentation/navigation for efficient mediation

– Inaccurate results (High false‐positive rate)• Loss of time spent evaluating • Loss of credibility for tool

– Slow / Batch / Offline

Best Practices for Ensuring ABAP code for Quality and Security

1. Online Scanning and Correction during Development

2. Testing of all Outsourced Deliverables (you are responsible!)

3. Automatic Scanning and Correction of SAP ABAP Changes

4. Static Code Analysis for ABAP

Best Practices

Online Scanning and Correction during Development– Define clear code standards, train, and test results!– Enable online scanning during development

• Developers scan during unit testing for immediate feedback• Fast mediation

– Automatic code correction – Provide detailed documentation for developer training and instructions for mediation

“since we’ve been using Virtual Forge CodeProfiler, developers have become more aware and are delivering better quality code.“ Stephan Sachs

Manager for Application Security

Best Practices : In-house Development

Best Practices: Data and Control Flow Analysis

Testing of all Outsourced Deliverables– Communicate and enforce SLA’s

• Let them know that you will be testing

– Test all deliverables before beginning functional testing• Don’t waste time functionally testing inferior code• Recommend 2‐4 weeks prior (at least)

– Test immediately? – is this code safe enough for your DEV? – Decide who will be responsible for corrections beforehand

• Plan for mediation activities – who is responsible for corrections

“using CodeProfiler software for verifying all 3rd party code has revolutionized our way of working…We now have gained control over the coding quality and security risks"

Best Practice : Comprehensive Testing

Security Performance Quality

ABAP Firewall: Automatic Scanning of all SAP ABAP Changes– Scan all Transport Requests upon release– Stop Transport Requests with defects – do not allow release– Compliance testing and audit trail

• PCI, PII, SOX, FDA, Basil II, etc.

– Ready for emergency corrections• Bypass Firewall with approval• Track flaws for mediation later

“One of the key requirements was to defend our SAP systems against the project teams. Together with Virtual Forge we have been able to enforce sustainability for code quality and security“ Markus Seibel,

4. Benefits Summary

Lower Risk – Detect and support mediation of vulnerabilities

• Cyberattacks/Espionage• Performance/System failures• Data Theft/Fraud/Loss

– Test in‐/out‐sourced development and 3rd party add‐ons. • Enforces standards for all development deliverables • Clear and enforceable definition of programming standards

– Ensure all ABAP code changes meet Compliance and Audit requirements

Benefits of Best Practices

Lower TCO• Find problems earlier in SDLC

= Lower cost to mediate defect• better quality code (maintainability, performance, robustness)

= Lower test and maintenance costs • Reduce review & testing times

= Faster delivery of new applications • Automate scanning and review

= Less use of (expensive) development resources• Online scanning & mediation support for faster resolution

= Less time for corrections and repair• Better quality code

= Less SAP production system issues
