Question

Security issues between JSP and Applets

Asked by: orjun

hi guys,
i wanted to know if there were any kind of security issues on the server side if an applet or any java program is embedded in the JSP and run from the Server Side,

since i think... when an Applet is loaded from a JSP on the server side a trusted connection between client and server is established and hence technically the client can send viruses or other unwanted code through this trusted connection to the Server Side. how can this be prevented ??

Thanx in Advance
Regards,
Orjun

I  don't  think  that  is  really  a  potential  problem.

1)  The  applet  is  downloaded  from  the   server. So  the access  of  the   system or what  the  applet  can  actually  do  is   dictated  by  the  applet  itself.
2)  I  don't  think  there  is  any  difference  between  loading    applet  from    a  plain  html  and  from  a  jsp  ,  because  ,  JSP  is  finally  getting  compiled  to  a  servlet  and  all  the  servlet  can  send  back  is  html.
So  when  the  JSP  is  invoked ,  a  html  is  returned  which  has  a  link  to  the applet . When  the  browser  comes  across  this   applet tag  link ,
it  fetches  it  as  a  seperate  request.

So I  think   security  is same  as  that  of  a  applet  loaded  by  a  html

the applet does not run on the server, even if its embedded in a jsp or asp or php or whatever page.
the applet always run on the client machine.
therefor, the answer to your question is no.
applet does not have security issues that are jsp related.
(but they have planty of security issues that are not).

We  talk  of  access  restrictions  ,  tight  security  restrictions  with  respect  to    protecting  the  client  machine   from  malicious  attacks   from   applets  downloaded  from  unknown  sites.

So  protecting the  server  is  really  not  a  issue  as  the  applet  that  is  downloaded  from  your  server  can  only  do,  what  you  program  it  to  do.

The  point  also  to  be  noted  is  that   only  the  applet  can  use  the  connection  it  makes  with  the  server ,.  The  client  cannot  just  send  some  virus  or  other  unwanted  code  as  raised  by  your  concern.
