3 Access to information on Multics is discussed in five separate
4 sections below. The sections are named:
5
6 Access class
7 Access control
8 Access control list ACL
9 Access isolation mechanism AIM
10 Access modes
11
12
13 Access class:
14 An access isolation mechanism AIM attribute that denotes
15 the sensitivity of information contained in a segment, directory,
16 multisegment file, or message in a message segment. An access class
17 is associated with an entry for its lifetime.
18
19
20 Access control:
21 The mechanism for determining who can reference or modify
22 segments files and directories.
23
24
25 Access control list ACL:
26 A set of access identifiers specifying who can access a segment
27 or directory. Associated with each access identifier is a set of
28 allowed modes of access to that segment or directory. There is an ACL
29 for each segment and each directory.
30
31
32 Access isolation mechanism AIM:
33 The mechanism used to guarantee that only authorized persons
34 access certain classes of information. See access_isolation.gi.info
35 for more information. See aim_use.gi.info for notes and suggestions
36 for users who plan to use the Access Isolation mechanism.
37
38
39 Access modes:
40 A way to identify the kinds of access that can be set for a
41 segment or directory. The access modes for segments are read r,
42 write w, execute e, and null n. Those for directories are
43 status s, modify m, append a, and null n.
44
45 For information on extended access modes for a mailbox, see
46 extended_access.gi.info.

48
49 :Info: active_function.gi: 02/04/82 active function
50
51 A function specified in a command line whose value a character
52 string becomes part of an expanded reevaluated command line.
53
54
55 :Info: AIM.gi: aim.gi: 02/04/82 AIM Access Isolation Mechanism
56
57 The mechanism used to guarantee that only authorized persons
58 access certain classes of information. See access_isolation.gi.info
59 for more information. See aim_use.gi.info for notes and suggestions
60 for users who plan to use the Access Isolation mechanism.
61
62
63 :Info: ACL.gi: acl.gi: 02/11/82 ACL Access Control List
64
65 A set of access identifiers specifying who can access a segment
66 or directory. Associated with each access identifier is a set of
67 allowed modes of access to that segment or directory. There is an ACL
68 for each segment and each directory.
69
70
71 :Info: alternate_name.gi: 02/04/82 alternate name
72
73 A segment, directory, multisegment file, or link can have more
74 than one name and may be referred to equally well by any one of its
75 names. One of the names is the primary name. A segment often has
76 more than one name because it is a program with alternate entry
77 points; commands often have short names as well as long ones for
78 convenience in typing i.e. cwd instead of change_wdir.
79
80
81 :Info: answering_service.gi: 02/04/82 answering service
82
83 The subsystem that runs in the Initializer process and logs users
84 in and out.
85
86
87 :Info: archives.gi: 02/04/82 archives
88
89 Segments used to conserve space. When storing a group of
90 segments, the contents of the individual segments can be packed
91 together in an archive to eliminate breakage in the last page of each
92 segment. Segments placed in an archive are called archive components.
93 See the description of the archive command.
94
95
96 :Info: attach.gi: 02/04/82 attach
97
98 The act of associating an I/O switch with a file, or other I/O
99 switch. For example, the normal output switch user_output is
100 usually attached to the terminal, but can be attached to a file via
101 the file_output command.
102
103
104 :Info: authorization.gi: 02/04/82 authorization
105
106 An access isolation mechanism AIM attribute of a process
107 that denotes the range of information the process can access. An
108 authorization is associated with a process for its lifetime.
