Three basic security policies are specified: [6] Mandatory Security Policy – Enforces access control rules based directly on an individual's clearance, authorization for the information and the confidentiality level of the information being sought.
In Excel and Word 95 and prior editions a weak protection algorithm is used that converts a password to a 16-bit verifier and a 16-byte XOR obfuscation array [1] key. [4] Hacking software is now readily available to find a 16-byte key and decrypt the password-protected document. [5] Office 97, 2000, XP and 2003 use RC4 with 40 bits. [4]
The threat model does not guarantee protection against very persistent and skilled attacks, for instance by organised crime groups or by foreign governments; these are possible, but normal controls would make them more difficult, and much stronger controls would be disproportionate.
Advanced solutions can also provide similar protection on computer endpoints, or cloud email and file sharing services. There are three levels of CDR; 1) flattening and converting the original file to a PDF, 2) stripping active content while keeping the original file type, and 3) eliminating all file-borne risk while maintaining file type ...
