System Administration and the Environment

David Douthitt

For a system administrator who works with computers in the data center all day there are at least two areas where you can help daily: data center electricity use, and paper use. The data center is becoming responsible for an ever increasing amount of electricity use, and generators are already maxed out in many locations in the country. Reducing electricity usage in the data center will not only reduce the need for electricity, it can also reduce your corporate electric bill. Paper, while being a renewable resource, is taking its toll on the trees that exist on our planet (along with the need for lumber world-wide). The biggest problem is that trees are being consumed faster than they can be regenerated - trees take many years to grow, and only minutes to take down.

Java Image Information Leakage And Another Theory

I’ve been sitting on this one for about two years now, and I still haven’t done anything with it, nor do I think it can really work in the way I originally came up with, but I thought it might be better to throw it out to the public in case anyone else has something ingenious in their heads. Several years back when I was first working on cross domain leakage I realized that Java has access to images pulled from remote sites. You can see this with fun things like waves in images or whatever. Flash pretty much took over where Java left off, so not a lot of people went beyond that for animation (what’s the point when Flash makes it so easy?).


Assessing Information Security Vulnerabilities – Are They Really ...

Find vulnerabilities on the computers on your network; apply a patch, and all done, right? Well, maybe, and maybe not. Part of any good security program includes using a variety of tools to assess the risks in your environment. Specifically, I am talking about the periodic vulnerability assessments that are performed on the desktop and server computers in your network. Let’s assume you are an all Windows shop for the moment; On the most fundamental level, you get this risk assessment done for you every time you visit the Windows Updates site on the Internet. The Windows Update site uses a scanning engine to determine what is installed on your computer, what the most current patching levels are, and whether or not your computer has those patches. Same with your antivirus software – you are given the latest updates based on the most currently known threats and whether or not you currently have the definitions for those threats (in this case viruses).


Exponential information growth

YouTube, a company that didn’t exist just a few years ago, hosts 100 million video streams a day. Experts say more than a billion songs a day are shared over the Internet in MP3 format. Digital bits. London's 200 traffic surveillance cameras send 64 trillion bits a day to the command data center. Chevron's CIO says his company accumulates data at the rate of 2 terabytes – 17,592,000,000,000 bits – a day. TV broadcasting is going all-digital by the end of the decade in most countries. More digital bits. …


Botnet Communication Platforms

Botnets, or the automated exploitation and management of malware infected PCs is perhaps the most popular and efficient cyber threat the Internet faces these days. Whether you define it as the war on bandwidth or who's commanding the largest infected population, this simple distributed hosts management problem is continuing to evolve in order for the botnet masters to remain undetected for as long as possible. On the other hand, the growing Internet population combined with the lack of awareness of the "just got a PC for Christmas" users, and IPv4's well known susceptability to IP spoofing compared to IPv6, always make the concept an interesting one to follow.
