My Company never used updates because we install our own Software and in the old days it created problems. Now due to Shell Shock, they finally want to. But they only want the Security Patches and they want me to set up Server here and not use the on-line/mirror Servers. Is there any way that I can download just the Security Patches that we need and save them here?
