The technical and nontechnical vulnerabilities associated with an IT system’s processing environment can be identified via the information-gathering techniques described in Section . A review of other industry sources (., vendor Web pages that identify system bugs and flaws) will be useful in preparing for the interviews and in developing effective questionnaires to identify vulnerabilities that may be applicable to specific IT systems (., a specific version of a specific operating system). The Internet is another source of information on known system vulnerabilities posted by vendors, along with hot fixes, service packs, patches, and other remedial measures that may be applied. | Simulation of Ground-Water Flow and Evaluation of Water-Management Alternatives in the Assabet River Basin Eastern Massachusetts By Leslie A.
