` Greetings and Felicitations!
`Puzzle of the Day
`User identification
P `>Go through UNIX idea of real, effective, saved, audit
Q `BGo through notion of role accounts; cite Secure Xenix, DG, etc.
R `%Go through PPNs (TOPS-10) and groups
S `Review least privilege
`Notion of privilege
` Identity
`Functionality
` Granularity
`Privilege in OSes
`ENone (original IBM OS; protect with password, or anyone can read it)
`-Fence, base and bounds registers; relocation
`Tagged architectures
O `NMemory management based schemes: segmentation, paging, and paged segmentation
X `"Different forms of access control
Y ` UNIX method
Z `"ACLs: describe, revocation issue
[* )MULTICS rings: ( b 1 , b 2 ) access bracket - can access freely; ( b 2 , b 3 ) call bracket - can call segment through XUUU @ gate; so (4, 6, 9) as example HH 5 HH l d :> !! $$ :? $$ "B! G
