What is Penetration Testing? Based on Vulnerability Analysis –A search for vulnerabilities in the TOE or its intended operation –Analysis of their impact Tests formulated and run Exploitability of vulnerabilities determined

Where do the tests come from? Vulnerability Analysis Penetration Testing Design Analysis Functional Testing Operational Assessment

Types of Testing Positive –covered under functional testing Negative or destructive Compound testing –testing more than one aspect of functionality at once

Planning Should have most of the ideas before you start testing (on-site or in the CLEF) Formal test scripts may help Agree work split before you go Agree how tests will be documented

Be considerate to the developer Live system testing –save destructive tests for out-of-hours Their baby –be sensitive to their feelings ! –especially if on site Restore the TOE to a clean state

Additional Tests Inspiration during Penetration testing Know when to stop Record Test Activity and Progress

ITSEC and CC Requirements ITSEC –Requirement to Perform Penetration Testing for all assurance levels E1 - E6. CC –Requirement to perform Penetration Testing for assurance levels EAL2 - EAL7.

Typical Penetration Testing Form

Evaluation Reporting Tests Run Test Results Anomalies Conclusions

Summary Goal of Penetration Testing Refinement of Ideas from Vulnerability Analysis Plan Carefully Record Everything relevant for repeatability
