One of my programmer buddies refers to this process as "turd polishing" because, as he says, it doesn't make your code any less smelly in the long run but management might enjoy its improved, shiny, appearance in the short term.

Richard Feynman's " Personal Observations on the Reliability of the Space Shuttle " used to be required reading for the software engineers that I hired.

It contains some profound thoughts on expectation of reliability and how it is achieved in complex systems.

In a nutshell its meaning to programmers is: The premise of the "vulnerability researchers" is that they are helping the community by finding holes in software and getting them fixed before the hackers find them and exploit them.

The premise of the vendors is that they are doing the right thing by pushing out patches to fix the bugs before the hackers and worm-writers can act upon them.

Both parties, in this scenario, are being dumb because if the vendors were writing code that had been designed to be secure and reliable then vulnerability discovery would be a tedious and unrewarding game, indeed! Let me put it to you in different terms: What has it been?

If you look at major internet applications you'll find that there are a number that consistently have problems with security vulnerabilities. There are also a handful, like PostFix, Qmail, etc, that were engineered to be compartmented against themselves, with modularized permissions and processing, and - not surprisingly - they have histories of amazingly few bugs.

The same logic applies to "penetration testing. That's because their design or their security practices are so fundamentally flawed that no amount of turd polish is going to keep the hackers out. It just keeps managers and auditors off of the network administrator's backs. I know other networks that it is, literally, pointless to "penetration test" because they were designed from the ground up to be permeable only in certain directions and only to certain traffic destined to carefully configured servers running carefully secured software.

Running a "penetration test" for Apache bugs is completely pointless against a server that is running a custom piece of C code that is running in a locked-down portion of an embedded system. So, "Penetrate and Patch" is pointless either because you know you're going to find an endless litany of bugs, or because you know you're not going to find anything comprehensible.

One clear symptom that you've got a case of "Penetrate and Patch " is when you find that your system is always vulnerable to the "bug of the week.

Doesn't that sound dumb? Your software and systems should be secure by design and should have been designed with flaw-handling in mind. That's a dumb idea. One of the best ways to discourage hacking on the Internet is to give the hackers stock options, buy the books they write about their exploits, take classes on "extreme hacking kung fu" and pay them tens of thousands of dollars to do "penetration tests" against your systems, right?

Around the time I was learning to walk, Donn Parker was researching the behavioral aspects of hacking and computer security. He says it better than I ever could: Anonymity and freedom from personal victim confrontation increased the emotional ease of crime, i.

Timid people could become criminals. The proliferation of identical systems and means of use and the automation of business made possible and improved the economics of automating crimes and constructing powerful criminal tools and scripts with great leverage.

It's not a technology problem, at all. The 4th dumbest thing information security practitioners can do is implicitly encourage hackers by lionizing them.

The media plays directly into this, by portraying hackers, variously, as "whiz kids" and "brilliant technologists" - of course if you're a reporter for CNN, anyone who can install Linux probably does qualify as a "brilliant technologist" to you.

I find it interesting to compare societal reactions to hackers as "whiz kids" versus spammers as "sleazy con artists. If you're a security practitioner, teaching yourself how to hack is also part of the "Hacking is Cool" dumb idea.computer security Essays: Over , computer security Essays, computer security Term Papers, computer security Research Paper, Book Reports.
