It sounds like your primary need is authentication along with some wiki or blogging functionality. Authentication decisions involve the level of security you need, the type of information being secured, available technology, etc. If simple HTTP authentication is adequate and your web app is running under Apache, you can use Apache's built-in authentication for directory-by-directory access with user info stored in a simple text file. Depending on the nature of your data, you may need encryption, SSL, ip restrictions, or a lead vault. If the site is being hosted, find out what tools are available. Most web hosts use Apache with Perl, PHP, and MySQL frequently installed. These host often provide some authentication services. If you want a wiki and PHP is an option, check out http://www.pmwiki.org/. If you are hosting the site locally, then the world is your oyster.
