Typically, in an assessment project for a web application or database with a large scale and scope, tasks required to be performed by a security analyst are such as SQL injection and penetration testing. To carry out these large-scale tasks, the analyst will have to perform 100 or more SQLi penetration tests on one or more target. This makes the process much more complex and much harder to implement. This paper attempts to compare large-scale SQL injections performed with Manual Methods, which is the benchmark, and the proposed SQLiAutoScript Method. The SQLiAutoScript method uses sqlmap as a tool, in combination with sqlmap scripting and logging features, to facilitate a more effective and manageable approach within a large scale of hundreds or thousands of SQL injection penetration tests. Comparison of the test results for both Manual and SQLiAutoScript approaches and their benefits is included in the comparative analysis. The tests were performed over a scope of 24 SQL injection (SQLi) tests that comprises over 100,000 HTTP requests and injections, and within a total testing run-time period of about 50 hours. The scope of testing also covers both SQLiAutoScript and Manual methods. In the SQLiAutoScript method, each SQL injection test has its own sub-folder and files for data such as results (output), progress (traffic logs) and logging. In this way across all SQLi tests, the results, data and details related to SQLi tests are logged, available, traceable, accurate and not missed out. Available and traceable data also facilitates traceability of failed SQLi tests, and higher recovery and reruns of failed SQLi tests to maximize increased attack surface upon the target.

Industrial control systems (ICS) used in industrial plants are vulnerable to cyber-attacks that can cause fatal damage to the plants. Intrusion detection systems (IDSs) monitor ICS network traffic and detect suspicious activities. However, many IDSs overlook sophisticated cyber-attacks because it is hard to make a complete database of cyber-attacks and distinguish operational anomalies when compared to an established baseline. In this paper, a discriminant model between normal and anomalous packets was constructed with a support vector machine (SVM) based on an ICS communication profile, which represents only packet intervals and length, and an IDS with the applied model is proposed. Furthermore, the proposed IDS was evaluated using penetration tests on our cyber security test bed. Although the IDS was constructed by the limited features (intervals and length) of packets, the IDS successfully detected cyber-attacks by monitoring the rate of predicted attacking packets.
