Security pre-requisites
• Request a X509 host certificate for the User Interface you are going to install from a Certification Autority (CA). For example, to get host certificates from the GILDA CA, go to: https://gilda.ct.infn.it/CA/mgt/restricted/srvreq.php
• Install host certificates (hostcert.pem and hostkey.pem) in /etc/grid-security chmod 644 hostcert.pemchmod 400 hostkey.pem
• If you plan to use certificates released by unsupported EGEE CA’s, be sure that their public key, signing policy and CRLs (usually distributed with an rpm) are installed in /etc/grid-security/certificates
– For the VO GILDA, the RPM is available from https://gilda.ct.infn.it/RPMS/ca_GILDA-1.0-2.i386.rpm
