Libby, a new hire in the IT department, approaches you, her supervisor, ashen-faced. A few minutes earlier, the president of the company called the help desk and asked Libby to give his new assistant the permissions needed to access his personal budget spreadsheet. As she was attempting to assign the permissions, she accidentally deleted the BUDGET_USERS group from the spreadsheet’s access control list. Libby is terrified because that group was the only entry in the file’s ACL. Now, no one can access the spreadsheet file, not even the president or the Administrator account. Is there any way to gain access to the file, and if so, how?
