18 Assessment Evaluation Test Suite 1: Operating Snort Test #SR #DescriptionExpected OutcomeActual Outcome TS1.1SR2.1 SR2.5 The user will click the Start Snort button to start Snort. Snort status table will display “ Snort Started ”. The Start Snort button will change to Stop Snort button. Same as Expected TS1.2SR2.2 SR2.5 The user will click the Stop Snort button to stop Snort. Snort status table will display “ Snort Stopped ”. The Stop Snort button will change to Start Snort button. Same as Expected

19 Assessment Evaluation Test Suite 2: Operating SnIPS Test #SR #DescriptionExpected OutcomeActual Outcome TS2.1SR3.4 SR3.7 SR3.10 SR4.2 The user will click the Set Time Frame button to set the start and end time for SnIPS and click Ok button after the start and end time is selected. SnIPS status table will display the start and end time. Pre- processing and DoAll button is now enabled. Same as Expected TS2.2SR3.4 SR3.10 SR4.2 The user can cancel setting the start and end time by clicking the Cancel button in the pop-up frame from Set Time Frame button No ChangeSame as Expected TS2.3SR3.1The user will click the Pre-processing button based on the time frame in TS2.1 for running SnIPS pre-processing. A pop-up message box will show up displaying the “ obs_xxx.P ” file name is created. Summarization button is enabled at this time. Same as Expected

20 Assessment Evaluation Test Suite 2: Operating SnIPS Test #SR #DescriptionExpected OutcomeActual Outcome TS2.4SR3.2The user will click the Summarization button based on the time frame in TS2.1 for running SnIPS summarization. A pop-up message box will show up displaying the “ summ_xxx.P ” file name is created. Trace button is enabled at this time. Same as Expected TS2.5SR3.3The user will click the Trace button based on the time frame in TS2.1 and select optional query for XSB engine for running SnIPS trace. A pop-up message box will show up displaying the “ result.txt ” file name is created. Backtrack Output button is enabled at this time. Pop-up message didn ’ t show up. Error Message: unexpected input. Solved ! TS2.6SR3.8 SR4.1 SR4.2 The user will click the Back Track button to show the SnIPS proof strengthening results. The proof strengthening results are shown in web- based by the browser. Same as Expected TS2.7SR3.5The user will click the DoAll button to show the resunt SnIPS operation for SR3.1 ~ 3.3 and SR 3.8 The proof strengthening results are shown in web- based by the browser. Same as Expected

21 Assessment Evaluation Test Suite 3: Trace Output Webpage Test #SR #DescriptionExpected OutcomeActual Outcome TS3.1SR5.1The user will click the links provided in web-based proof strengthening result to show primitively summarized alerts. Primitively summarized alerts for each proof strengthened result will be shown. Same as Expected TS3.2SR6.1The user will click the links next to the primitively summarized alerts provided in web-based proof strengthening result to show alert payload. Payload for each alert will be shown. Same as Expected TS3.3SR7.1The user will click the links named with SID provided in web-based proof strengthening result to show triggered Snort rule. The Snort rule triggered by the SID alert will be shown. Same as Expected TS3.4SR7.2The user will click the Snort rule description link provided in Snort rule webpage. The Snort rule description will be shown with the same SID as in TS7.1 Same as Expected
