Table 5. Predefined qualifiers (continued)
Prerequisite property Platform Description
os.SELinux Linux
os.ulimit UNIX
Common category without predefined subtype
Checks the enforcement status of the
Security-Enhancement Linux feature
based on the following qualification
attributes:
v source attribute, to determine the
command to use for the relevant
operating system
Use this naming convention for
checking whether an unlimited number
of processes can be run based on the
following qualification attributes:
v type attribute, to determine which
additional limit to check, for
example, the filedescriptorlimit
checks the limit for the number of
file descriptors that processes can
open
Valid qualifiers and values
v String with the following qualifier
format:
[source:Command]
Disabled|Enabled
For example, to check whether the
feature is disabled or has a
permissive status on either Red Hat
or SUSE operating system:
os.SELinux=[source:
Command]Disabled
v String without a qualifier, where the
operating system is a generic Linux
variant:
os.SELinux=Disabled
String with the following qualifier
format:
[type:limit_name]limit_value,
limited|unlimited
For example, to check whether the file
descriptor limit is greater than 8192,
with unlimited number of processes:
os.ulimit=
[type:filedescriptorlimit]
8192+,unlimited
Valid types of limits to check, where
limit_name represents the type of limit
are as follows:
v ALL, checks all limits
v corefilesizelimit
v datasegmentlimit
v filedescriptorlimit
v filesizelimit
v hardlimit
v processlimit
v maxmemorysizelimit
v maxprocesseslimit
v stacksizelimit
v threadlimit
