In some extent, different kind of vulnerability assessment and penetration testing may impact on target system. I am looking for the solution/rollback process if something goes wrong during test.
For example, to check the stress absorbing capacity of any server DoS attack testing might me one solution. During DoS/DDoS attack target system may be interrupted in service or totally shut down. In this case, we need to pause the testing or decrease the amount of packets sent to the target system. Additionally we can restart our clients targeted server if any change happen which might impact the service of the target machines.
I am not sure I have make an example of rollback process/procedure for a part of vulnerability assessment. By the way, if anyone knows some other rollback process might be necessary during/after vulnerability assessment and penetration testing, please give me your valued opinion/suggestion regarding this issue.
