accepted for providing authenticated and encrypted communication between clients and servers to
prevent eavesdropping across a network.
An SSL-enabled system can perform the following tasks:
• Authenticate itself to an SSL-enabled client
• Allow the two systems to establish an encrypted connection
The encryption process provides a high level of data protection. Server Administrator uses the most
secure form of encryption generally available for Internet browsers in North America.
Server Administrator Web server has a Dell self-signed unique SSL digital certificate by default. You can
replace the default SSL certificate with a certificate signed by a well-known Certificate Authority (CA). A
Certificate Authority is a business entity that is recognized in the Information Technology industry for
meeting high standards of reliable screening, identification, and other important security criteria.
Examples of CAs include Thawte and VeriSign. To initiate the process of obtaining a CA-signed certificate,
use the Server Administrator Web interface to generate a Certificate Signing Request (CSR) with your
company’s information. Then, submit the generated CSR to a CA such as VeriSign or Thawte. The CA can
be a root CA or an intermediate CA. After you receive the CA-signed SSL certificate, upload the certificate
to Server Administrator.
For each Server Administrator to be trusted by the management station, the SSL certificate of that Server
Administrator must be placed in the certificate store of the management station. After the SSL certificate
is installed on the management stations, supported browsers can access Server Administrator without
certificate warnings.

Upgrading web server
CAUTION: Factory reset is not possible after a web server update. For a factory reset, reinstall the
Server Administrator.
You can upgrade the Apache Tomcat web server, whenever required, using the omwsupdateutility,
without affecting the Server Administrator functionality. The utility allows upgrade to a minor version of
web server, but does not support upgrade to a major version. For example, upgrade from version A.x to
A.y is supported, but not A.x to B.x or B.y. Also, using the utility you can move the version of the web
server to an earlier version, provided it is a minor version. The utility is saved to the following default
location during web server installation:
• On systems running a Windows operating system: C:\Program Files\Dell\SysMgt\omsa
\wsupdate
