The security of two software systems are compared. A total of 225 security tests (fake attacks) were carried out on System 1 and, in 100 of them, the system was unaffected. On the other hand, 175 tests were conducted on System 2 and, in 40 of them, the system remained unaffected. Help test engineers decide whther there is a meaningful difference between the security levels of two systems (measured by the proportion of unsuccessful attacks) by building a confidence interval.
