<h1>Security Considerations </h1>
|
|
|
|
This series of web pages uses direct calls to the unix shell
|
|
and is therefore potentially vunerable to tampering and
|
|
spoofing unix commands to be run as part of the typed in data.

|
|
limited privilages.
|
|
<br><br><img SRC="red_bullet_half.gif"> All input fields from forms and hidden variables are syntax checked (they must only contain digits).
|
|
<br><br><img SRC="red_bullet_half.gif"> The processing requirements on this server are very high.
|
|
The processor load will regularly go to 99% when performing RSA size calculations.
|
|
The size of input values are therefore checked. If extremely large values
|
|
were requested for instance, the server would appear to hang.
