This is the second part of a two-part tutorial on security. The first part highlighted technical essentials for the newbie, terminology of the basics areas of security, network, system, and physical environments. This second part will look at prevention and what to do when you've been hacked. Christine will attempt to cover the components that make up a system and highlight primary areas of concern.
Christine Wanta has been in the IT industry over 20 years. She has worked in a variety of positions, including creating a consulting firm. She has worked with a variety of systems including VMS, Windows and UNIX platforms, and heterogenous networked environments, and has supported a variety of applications including object-oriented designs, databases, proprietary software support, performance analysis and more. She was recruited as a certification writer for the Usenix/SAGE certification program in 2000.
Christine has been an active member of SLUUG for over a decade and currently acts as president. If you are 'impressed' into a project or positions within SLUUG, you probably have Christine nudging you.
Agile Programming is a set of methodologies intended to enhance and speed up program development. Extreme Programming (XP) is the most popular, but only one of the Agile Programming methods. Agile Programming focuses on agility and flexibility, realizing that things change throughout the lifetime of a project.
Since the end of the tech boom cycle, corporate software development organizations have been shrinking. These groups are usually cost centers in large companies, and are one of the first groups cut during tough times. Despite this fact, these same companies are demanding a steady stream of new applications from these groups. And each new application must justify itself by providing a rapid return on the corporate investment in them.
Starting from first principles, Brian will evolve and describe a software development methodology tailored to deliver value in the tech environment in which we live today. He will discuss the principles behind the Agile Software movement and describe how one particular methodology, Extreme Programming, produces teams and projects that thrive in today's economy. Brian will give an overview of Extreme Programming and then focus on how following the XP Developer Practices (Simple Design, Pair Programming, Test First Design, and Refactoring) leads to teams that create amazingly high quality software in short iterations, and have a great time doing it.
Brian Button is the co-founder of the St. Louis Extreme Programming users group (XpStl). He is also founder and principal consultant at Agile Solutions Group, a software improvement company that works with small to medium sized companies, generally those who don't write software as their business, but need software for their business. He teaches them how to save money through better management and implementation techniques.
Brian has over 15 years of industry experience as a developer and as a leader. Brian is very experienced in introducing and implementing Extreme Programming in many organizations, handling the entire transition efforts himself. His technical qualifications include 10 years experience in Object Oriented Design and Programming and C++, 5 years experience in Java. He has presented at conferences, written articles for national publications, and is well known in his field as an instructor, consultant, and mentor.
Prior to forming Agile Solutions Group, Brian was a Senior Consultant at Object Mentor, Inc. In this role, Brian functioned as the architect for several 3-tier web-enabled projects, taught numerous classes worldwide in C++, Java, basic and advanced Object Oriented Development, Test Driven Development, and Extreme Programming, mentored hundreds of programmers into becoming better developers, and transitioned several large organizations to Agile Development and Extreme Programming.

Have you looked at Red Hat 9 and wondered what the heck NPTL is? For that matter, what are threads and why should I care? If you have, then this Linux meeting is for you. Rich will start with the basics of threads -- how they differ from process, and why they are used. He will discuss the benefits and problems encountered when building treaded programs. The differences between NPTL (Native POSIX Thread Library) and the Linux threads currently in use will then be covered.
Rich Seibel is Senior Software Engineer at Object Computing Inc.

The big news in the UNIX/Linux world is the $1 billion SCO lawsuit against IBM. In case you haven't been paying attention, SCO has accused IBM of misappropriating trade secrets by transferring technology from UNIX (via AIX and the failed Monterey project) to Linux.
While the community has been worried about what might happen to Linux, there's something more immediate to worry about: AIX. SCO says that it will revoke IBM's license to the core UNIX code on June 13. SCO has not yet taken any legal actions against Linux itself; they've only made threats. So the threat to AIX is much more immediate than to Linux. Some analysts are advising companies to be wary about deploying Linux in critical areas. I have not heard any analyst advise AIX customers to be wary, but if SCO revokes the license, companies may not be able to expand their use of AIX systems. It seems rather odd that analysts are more concerned about mere threats than direct legal action. One theory is that IBM has enough money to post a bond to continue selling AIX even in the face of an injunction, and that IBM will indemnify their customers from liability.
SCO's behavior has been inconsistent and erratic to say the least. Their claim states that Linux could not have gained "enterprise" features without help from IBM, using code and knowledge from core UNIX code. But SCO's UNIX doesn't even include such features. The lawsuit is based on trade secrets and contracts, but then SCO began making claims about Linux containing their copyrighted code. SCO's executives first claimed that it wasn't the Linux kernel that contained the "stolen" code, but then changed their story. They won't tell anyone what code in Linux came from UNIX without a very strict Non-Disclosure Agreement. (Very few have taken SCO up on the offer.) But if the code is already in Linux, it's already out there; and even if it's removed quickly, SCO can just show that it was in previous versions -- there are thousands of copies of every previous version of the Linux kernel to be found on the Internet and Linux CDs.
The leading theory is that SCO is just making a last-ditch effort to get acquired. Their SCO UNIX business has been slipping for years. They had one or two good versions of Linux (as Caldera), but recent versions have fallen behind. (And they stopped selling their own version of Linux a few days after they made the accusations of Linux containing their code.) They still make some money on services. But a significant portion of their income now comes from licensing their Intellectual Property, including the core UNIX code. That portion is growing -- they've created a separate division just for source licensing, and they've hired lawyers to pursue any possible violations. And Microsoft just recently purchased a license to the UNIX code for $10 million. (It's for their Interix and Services For UNIX products, but it's unclear why they didn't need the license before now.)
Asked about why SCO didn't take action against Linux source code until recently, SCO's CEO said "Even if you potentially had a problem [with concerns about UNIX code in Linux back then], what are you going to do? Sue Linus Torvalds? And get what?" Which may mean that SCO knew of any infringement before, but waited until it was more profitable for them to sue. While it isn't required to sue for infringement of copyright violations immediately, it is against the law to knowingly wait in order to cause more violations.
Even if it turns out that there is some shared code in UNIX and Linux, does it mean that Linux is in violation of SCO's copyrights? Not necessarily. It's possible that the code came from a 3rd-party source, perhaps BSD. Maybe the code is a small enough portion that there's really only one way to do the same thing. Books have been published with operating system source code, including some older versions of UNIX. Lots of people have seen the UNIX source code; it's possible that so many have seen it that it's no longer considered a secret. Can SCO prove that the code was taken from their UNIX, or might they have stolen the code from Linux? Some former Caldera developers have reported that the latter may be the case. (It should be fairly easy to show which direction the code went, by looking at its evolution over various versions of Linux.) Since SCO has previously sold Linux, it's hard for them to deny that they did not agree to the terms of the GPL. And since the code is included, it's hard for them to deny that they did not knowingly do so. Once they've licensed their code under the GPL, they really can't take it back. Novell has even raised questions about whether SCO owns the copyrights to the UNIX code after it was transferred from Novell.
How much do we really need to worry about SCO's threats to Linux? Everyone agrees that all of SCO's accusations are unlikely to pan out. The biggest effect on Linux will probably be the Fear, Uncertainty, and Doubt (FUD) created in the minds of company executives, wondering if it's safe to use Linux. Is there real liability for users? Probably not too much. Copyright law only concerns copying, modifying, and distributing -- it does not pertain to the use of copyrighted materials. (If a book at the library is found to have been plagiarized or stolen, are people who have read the book held liable?) So if you've bought and paid for a copy of Linux, it's the seller who is liable. So as a user, you should only be liable if you've copied or modified Linux.
There's a lot of info (and speculation) about the SCO case to be found on the Internet. Be sure to check out Linux Weekly News, Slashdot, the Open Source Initiative, Google News, and all the other usual sources.

Sharing is fine unless it's software or music. That's what I was taught in kindergarten anyway. It would appear that SCO has about the same grasp of reality as did the infamous Iraqi information minister, Mohammed Saeed al-Sahaf, in the closing days of the war in Iraq. -- http://comment.zdnet.co.uk/story/0,,t479-s2134763,00.html If Darl McBride and complainants did not know at the time of the complaint that Caldera itself had played a lead role in the very development they accuse IBM of having unfairly and unlawfully pursued, they are incompetent. If they did know, their complaint appears to verge closely upon perjury. -- ESR, http://www.opensource.org/sco-vs-ibm.html Contracts are what you use against parties you have relationships with. From a legal standpoint, contracts end up being far stronger than anything you could do with copyrights. -- SCO Funny, I thought "Contracts" were a method for doing business in good faith with people, not just something to be used for frivolous lawsuits.... -- wrero on Slashdot Statistics are like a bikini. What they reveal is suggestive, but what they conceal is vital. -- Aaron Levenstein
