<p>Information content security can be defined in many ways. The most common
way is to determine the confidentiality, integrity, and availability of information.</p>
<ul>
<li><p>Confidentiality defines the privacy level of the information
and the importance of its content to critical operations. There may be different
levels of confidentiality, which are defined by the author and the policies
of the system. Information that is not classified as confidential is considered
public.</p></li>
<li><p>Integrity classifies information according to its importance
to operations. At the highest level of integrity, the information should remain
intact at all times, without fragmentation or delays in updates.</p></li>
<li><p>Availability is the most important factor if the information
must be accessible without interruption for operational reasons.</p></li>
</ul>
<p>By applying <xref href="GUID-A1ED2377-E196-423F-A5A2-1889C1CC3E05.dita">cryptography</xref> to
the elements above, you can introduce additional security features, such as
traceability, access control, authentication, and repudiation.</p>
<p>Any data that is stored in the application <codeph>\private\&lt;SID&gt;\</codeph> folder
can be considered safe, since other applications need the <codeph>AllFiles</codeph> <xref href="GUID-6971B0A2-F79B-4E05-8AF3-BB1FC1932A22.dita">capability</xref> to read
