<div class="p"> <dl class="dlexpand"><dt class="dltermexpand">Object</dt>
|
|
<dd>An <a href="../rzal2/rzal2objects.htm">object</a> is
|
|
a named space on the system that you or an application can manipulate. Everything
|
|
on the system that you or an application can work with is considered an object.
|
|
Objects provide a common interface for working with system components. The
|
|
most common examples of objects are files and programs. Other types of objects
|
|
include commands, queues, libraries, and folders. Objects on the system are
|
|
identified by object name, object type, and the library in which the object
|
|
resides. You can secure each object on the system. </dd>
|
|
<dt class="dltermexpand">Library</dt>
|
|
<dd>A library is a special type of object that is used to group other objects.
|
|
Many objects on the system reside in a library. Libraries are essentially
|
|
containers, or organizational structures for other objects, and you can use
|
|
them to reference other objects on your system. Libraries might contain many
|
|
objects, and might be associated with a specific user profile or application.
|
|
QSYS, which contains all other libraries on the system, is the only library
|
|
that can contain other libraries. Objects in a library are handled like objects
|
|
in a subdirectory. A library cannot live inside a directory.</dd>
|
|
<dt class="dltermexpand">Directory</dt>
|
|
<dd>A <a href="../ifs/rzaaxdir.htm">directory</a> is
|
|
a special object that provides another way to group objects on the system.
|
|
Objects can reside in a directory and a directory can reside in another directory,
|
|
forming a hierarchical structure. Each <a href="../ifs/rzaaxfsknow.htm">file system</a> is a major <strong>subtree</strong> in the integrated
|
|
file system directory structure. Directories are different from libraries
|
|
in that the address of each library maps to the QSYS library while directories
|
|
are not addressable. Names of libraries are restricted to 10 characters while
|
|
directories can have longer names which might be case sensitive. Directories
|
|
can have multiple names because the path to the directory is what is named
|
|
and not the directory itself. You would use different commands and authority
|
|
requirements when working with directories and libraries.</dd>
|
|
<dt class="dltermexpand">User profile</dt>
|
|
<dd>Every system user must have a user identity before they can sign on to
|
|
and use a system. This user identity is a special object called a <a href="rzamvuserprof.htm#userprof">user
|
|
profile</a>, which only an administrator with appropriate system authority
|
|
can create for a user.</dd>
|
|
<dt class="dltermexpand">Special authority</dt>
|
|
<dd><a href="rzamvspecialauth.htm#specialauth">Special authority</a> determines
|
|
whether the user is allowed to perform system functions, such as creating
|
|
user profiles or changing the jobs of other users.</dd>
|
|
<dt class="dltermexpand">Physical security</dt>
|
|
<dd><a href="rzamvplanphysec.htm#planphysec">Physical security</a> includes
|
|
protecting the system unit, system devices, and backup media from accidental
|
|
or deliberate damage. Most measures you take to ensure the physical security
|
|
of your system are external to the system. Certain system models are equipped
|
|
with a keylock that prevents unauthorized functions at the system unit.</dd>
|
|
<dt class="dltermexpand">Application security</dt>
|
|
<dd><a href="rzamvplanappsec.htm#planappsec">Application security</a> deals
|
|
with the applications you store on your system and how you will
|
|
protect those applications while simultaneously allowing users access to them.</dd>
|
|
<dt class="dltermexpand">Resource security</dt>
|
|
<dd><a href="rzamvresourcesec.htm#resourcesec">Resource security</a> on
|
|
the system allows you to define who can use objects and how objects can be
|
|
used. The ability to access an object is called <strong>authority</strong>. When you
|
|
set up object authority, you need to be careful to give your users enough
|
|
authority to do their work without giving them the ability to browse and change
|
|
the system. Object authority gives permissions to the user for a specific
|
|
object and can specify what the user is allowed to do with the object. An
|
|
object resource can be limited through specific, detailed user authorities
|
|
such as adding records or changing records. System resources can be used to
|
|
give the user access to specific system-defined subsets of authorities: *ALL,
|
|
*CHANGE, *USE, and *EXCLUDE. System values and user profiles control who has
|
|
access to your system and prevent unauthorized users from signing on. Resource
|
|
security controls the actions that authorized system users can perform, and
|
|
the objects that they can access after they have signed on successfully. Resource
|
|
security supports the main goals of security on your system to protect: <ul><li>Confidentiality of information </li>
|
|
<li>Accuracy of information to prevent unauthorized changes </li>
|
|
<li>Availability of information to prevent accidental or deliberate damage</li>
|
|
</ul>

</dd>

|
<dt class="dltermexpand">Security policy</dt>
|
|
<dd>A <a href="rzamvdevelopsecpol.htm#developsecpol">security policy</a> allows
|
|
you to implement and manage security on an i5/OS™ system. Use the <a href="../icbase/secplanr/securwiz.htm" target="_blank">eServer™ Security
|
|
Planner</a> to help you plan for and implement a basic security policy
|
|
for your servers. </dd>
