Final answer:
Jessica needs to get a sign-off on the scoping document from the stakeholders or clients to formalize their agreement with the scope of the penetration test and authorize her to proceed with the actual testing activities.
Step-by-step explanation:
After Jessica has filled out the scoping document for a penetration test, detailing what tools, techniques, and targets are to be included in the test, the next step she needs to take is to get a sign-off on the document. This sign-off is a formal approval from the relevant stakeholders or clients who authorized the penetration test. The sign-off indicates that they agree with the scope and terms laid out in the document and formally authorize Jessica to proceed with the penetration test. Once she has the necessary approvals, she can move forward with beginning the actual testing process, which might include passive fingerprinting, port scanning, vulnerability assessments, or other testing activities as outlined in the scoping document.
