Computer & Network Security Academic Essay | Write …
Let me put it to you in different terms: if "Penetrate and Patch" was effective, we would have run out of security bugs in Internet Explorer by now. What has it been? 2 or 3 a month for 10 years? 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." There are networks that I know of which have been "penetration tested" any number of times and are continually getting hacked to pieces. 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. Pointless is dumb.

Computer Security And The Threat Of Hacking Computer Science Essay
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:
"Remote computing freed criminals from the historic requirement of proximity to their crimes. Anonymity and freedom from personal victim confrontation increased the emotional ease of crime, i.e., the victim was only an inanimate computer, not a real person or enterprise. 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."
