Language
Language creates barriers and divides
Get the language right Critical High Medium Low Informational False
Positive
Security vulnerabilities hide behind acronyms, jargon and assumptions.

Vulnerabilities cluster between components
Our environments are complex
Bad things happen when low risk security issues cluster together…..
Automation
Human error threatens testing effectiveness
Test data creation and scrubbing Test case definition Load testing
Regression testing Integration testing Security testing Test environment deployment
Automated security testing gives a continuous assessment of risk.
