6	Static HTML service People, Org and Course Static HTML with Apache webserver on Linux RHEL No PHP, cgi-bin or other dynamic serverside components People: 750 users personal homepages Org: 96 sites Course: 9 sites Examples: http://folk.uib.no http://org.uib.no/tekna/ http://kurs.uib.no/litteraturglobaliseringfortelling/
7	Wiki service A solution for groups to add and change content, mainly text related. (A wikipedia thingy) Mediawiki software PHP, Apache webserver, Postgresql databases 74 wiki instances today 36 extensions (added modular functionality) Examples: https://wikihost/itwiki https://it.uib.no/en

10	Validating users Different solutions: ldap (wiki, people, org, course, hospits) kerberos (some few wiki’s) local users (wiki, blog)
11	How do users access services to update web-content? Web-interface Blog, Wiki and Hospits SSH/SFTP Hospits, People, Org and Course Samba (smb/cifs) Folk, Org and Course
12	Security Security breaches: Systems like Wordpress and Mediawiki reduces the probability Allowing users to add serverside code increases the probability Static HTML is very safe Hackers like Hospits :-) Potential security holes Difficult to test all sites because of variety in programming code provided by users Server security is intact root access is almost impossible to achive Apache user has limited rights Data is secured in version controlled TSM backup system Activites against hacker activity Email spam controll Nightly clamscan file-scan of all files on Hospits Firewall IPtables restrictions Sites on Hospits with security ”holes” are being closed down and web-content can be moved to the Blog or Wiki.
13	The future? What do we want Self-service users create their own sites on the fly Drupal multisite hosting Database hotel maybe? Oracle/Postgresql/Mysql Expanding core technologies (Python, Postgres, and others)
