Writing the report is easy if you have been collecting the information during each stage of your testing. It is important for the customer to always get a systematic assessment looking for classes of issues in unknown developer code so he/she can compare the results and always see a delta of new information.
A question I always ask is preassessment, is this project a baseline report or the 12th report of a single application/system in the current year? Either way the report needs to be consistent in the delivery to customers, management etc. The reason this is important, is that the 1st rule of security is to use multiple vendors for testing security right, but unless you specify a threat model type (see 5.1 How to value the real risk ) each report will have its own interpretation of risk and threats. If it does happen to be the 5th report on the same system, I typically submit an example report, and then ask the customer to compare "apples to apples". If he liked certain areas of the other firms report, I want to review how it will look on our report ahead of time. It’s all about meeting expectations. On the technical level, I am a fan of using the VISA/MasterCard PCI standard for host reporting.
The following sections are typically standard
I. Executive Summary - If this report is for many systems then there should be a summary paragraph that outlines the total devices tested, the dates of the testing and a summary of the results (Scope). I think we all know that management likes visual graphics to illustrate problems so why not provide some to depict all of the systems tested. II. Systems Summary – If more than 1 application or system is tested, we recommend that the systems summary defined the systems and the systems boundaries and a description of the systems purpose. Each “System” may contain many sub-systems etc., it is important to provide both Executive Summary about systems as well as within the systems summary. Appendix A, below would be ideal to illustrate per system the status of an Application Assessment and if you were to add a few items, you could include the host/network level as well.
III System Detail – This is a details on each system test and details of the individual hosts or applications again Appendix A would serve this purpose as a summary on a individual system level and then detailed information and recommended corrective actions to the found issues.
Within the system detail I like to utilize the following sections:
Keeping in mind as an assessment person that you can find the biggest issues in the world, but it is the customer/employer etc... That has to accept the facts and elect to fix them. So the report is exactly that, as a subject matter expert you are providing the facts good or bad. Think in context of testifying in a court of law as to what you observed, what you found and what you recommended this document is your professional deliverable.
IIII Toolbox - This is the area that is used to describe to the customer the commercial and open-source tools that were used in conducting the assessment. Keep in mind that in the proposal, typically is when you have submitted the BIO's of the human capital (people) that are doing the testing. When custom scripts/code is utilized during the assessment, it should be disclosed in this section or noted as attachment. The customer paid for the assessment and should be provided with a list of the tools used to provide the service in addition to the knowledge of the tester.
Some may argue that the tools used by other professionals when providing a service (Doctors, Mechanics, Lawyers etc.. )are not disclosed so why should we do this as a standard practice? I answer that question with this, the OWASP Testing Guide is FREE and OPEN-SOURCE and all of the sections of this guide provide a manual explanation of how to test. Some will automate the testing process to reach a result but, tools are only 40-60% of the work. We believe this guide is to provide details and best practices in not only in conducting testing but as a information security professional, full-disclosure of how a result was reached as there are always false positives right ;)
