"Practical and Free Security Tools" by Dave Dickerson, Maryville Data Systems, Inc.

Dave will discuss the implementation of tcp_wrappers, tripwire, swatch, and crack. These utilities, while available at no cost, are of incredible value in detecting that you are under attack and in assessing damages after an attack.

Dave has been a programmer, system administrator, network manager, and bottle washer using various Unix dialects for longer than he's willing to admit. Dave was a Systems Engineer for Sun Microsystems in St. Louis for 6 years, he managed a 250 node HP/UX network in the financial services industry for 2 years, and presently works as a Systems Engineer for Maryville Data Systems, Inc.


"Web Scripting -- CGI & Beyond" by Don Ellis

Although static HTML pages have a definite place on the web, there are several techniques that, while simple to implement, provide distinct improvements over the static page. We will review the potential of basic Common Gateway Interface (CGI), with linking to a database program; Server Side Include (SSI), which can improve automation of several routine tasks, and more; and a few Application Program Interface (API) methods, which allow the web administrator to essentially redefine the web server to her own taste.

Don Ellis has worked for computer consulting firms since 1986, previously working in sales support for several prominent manufacturers. He has had assignments on Unix systems, DOS PCs, and Macintosh installations. He is currently between projects.
