Appendix D.
Certificate setting for the company with Certificate Authority
Background information
Any website or high-value Web Applications will require a client to access their websites via Secure Sockets
Layer (SSL). The browser will automatically ask for a public SSL certificate from the website and check if it is
valid. The public SSL Certificate consists of the public key and identity information which can be signed by
any established certificate authority (e.g. VeriSign). The certificate authority guarantees that the public key
belongs to the named entity. Usually, website's security certificate encounters problem occurs only if the
security certificate presented to the browser has not been signed by any certificate authority which can be
trusted.
As long as the SSL function is enabled in the DSA-6100, there must be a public SSL certificate signed by an
established certificate authority. To avoid the error message in the browser, a company should have its own
Certificate Authority (CA). The IT department must therefore install the SSL certificate for each normal user
when deploying the DSA-6100.
Secure Certificate setting for both IE6 and IE7
For the company with its own Certificate Authority (CA), the certificate of the company should be trusted by all
his employees' computers, and the certificate should be delivered through a trusted media. For example, the
MIS staff should install the CA certificate in each computer. The company CA will issue a certificate for the
DSA-6100 and export it to the DSA-6100.
Note: If the DSA-6100 is installed in a company, the administrator can create a certificate using some
software instead of purchasing a public trusted certificate.
1) Certificate setting for the company without Certificate Authority
For a company that does not have it own Certificate Authority (CA), the administrators should first create a
certificate either by applying for a trusted one or by some certificate software. Second, the administrators
should use some trusted media to install this certificate (as trusted CA) in each employee's computer. In the
meantime, export this certificate to the DSA-6100.
In certain condition, the company without Certificate Authority can follow the steps below to avoid error
message. When in the LAN environment of the office rather than when in wireless environment,
administrators may already have recognized certificates in the system, which CA must be verified as secured.
