Operating Systems Solaris rbac and execution attributes (uid and euid) Post 302473552 by deadeyes on Sunday 21st of November 2010 10:34:41 AM

rbac and execution attributes (uid and euid)

Hi all,

I have a question to see if I understand the euid and uid attributes correctly for rbac (/etc/security/exec_attr):

Code:
All:
*
Audit Control:
/etc/init.d/audit euid=0, egid=3
/etc/security/bsmconv uid=0
/etc/security/bsmunconv uid=0
/usr/sbin/audit euid=0
/usr/sbin/auditconfig euid=0
/usr/sbin/auditd uid=0

If a role with a profile shell is running /usr/sbin/auditd, then what would the effective and real uid be?

As far as I understand they would be: uid=0 euid=0

Is this correct?
Or are there other factors that I should take into account?

Thanks in advance!

NAME
profiles - print execution profiles for a user SYNOPSIS
profiles [-l] [ user ...] The profiles command prints on standard output the names of the execution profiles that have been assigned to you or to the optionally- specified user or role name. Profiles are a bundling mechanism used to enumerate the commands and authorizations needed to perform a spe- cific function. Along with each listed executable are the process attributes, such as the effective user and group IDs, with which the process runs when started by a privileged command interpreter. The profile shells are pfcsh, pfksh, and pfexec. See the pfexec(1) man page. Profiles can contain other profiles defined in prof_attr(4). Multiple profiles can be combined to construct the appropriate access control. When profiles are assigned, the authorizations are added to the existing set. If the same command appears in multiple profiles, the first occurrence, as determined by the ordering of the profiles, is used for process-attribute settings. For convenience, a wild card can be specified to match all commands. When profiles are interpreted, the profile list is loaded from user_attr(4). If any default profile is defined in /etc/security/policy.conf (see policy.conf(4)), the list of default profiles are added to the list loaded from user_attr(4). Matching entries in prof_attr(4) provide the authorizations list, and matching entries in exec_attr(4) provide the commands list. The following options are supported: -l Lists the commands in each profile followed by the special process attributes such as user and group IDs. Example 1: Sample Output The output of the profiles command has the following form: example% profiles tester01 tester02 tester01 : Audit Management, All Commands tester02 : Device Management, All Commands example% Example 2: Using the list Option example% profiles -l tester01 tester02 tester01 : Audit Management: /usr/sbin/audit euid=root /usr/sbin/auditconfig euid=root egid=sys All Commands: * tester02 : Device Management: /usr/bin/allocate: euid=root /usr/bin/deallocate: euid=root All Commands * example% The following exit values are returned: 0 Successful completion. 1 An error occurred. /etc/security/exec_attr /etc/security/prof_attr /etc/user_attr /etc/security/policy.conf See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ auths(1), pfexec(1), roles(1), getprofattr(3SECDB), exec_attr(4), policy.conf(4), prof_attr(4), user_attr(4), attributes(5) 11 Feb 2000 profiles(1)
