Question 5

The biggest cost in regression testing is that of test case generation.

Answer 5

False

Question 6

Which of the following statements are correct?

Answer 6

• Even with modern security testing strategies cannot make strong statements about security.
• Although fuzz testing cannot provide complete confidence that software is secure, it is integral part of modern software development.

Question 7

Which types of failures resulting from fuzz testing indicate security flaws?

Answer 7

• crashes
• privilege escalation

Question 8

How can we perform fuzzing more effectively?

Answer 8

• Increase time of fuzzing
• Make the fuzzer smarter by obtaining more knowledge about systems.
• Use all kind of fuzzers with different techniques in parallel.

Answer 20

Identifying behaviors used only in rare events.
