Question: Several levels of file access were discussed in this chapter, including read/ write, read-only, execute-only, and no access. Assume you maintain a database containing confidential patient information and need to restrict UPDATE to only 5 individuals, allow only 15 others to view the database, and disallow any database access to all other users. Which access level would you assign to the 20 individuals in the first two groups and to the remaining users? For each of the three groups, describe every type of access granted to each one.
