1. Stamp out software bugs

2. Fortify the ISP's

3. Make the Penalty Fit the Crime

4. Companies, Cover your XXXX

5. Teach your children well


1. Stamp out software bugs

"More than 75% of the incidents we see

are the direct result of widely known

[software] bugs..."

CMU's Computer Emergency Response Team

"Chasing software perfection,

chasing the last bug, is not

what customers want...."

Microsoft's security response team



More comments on software bugs

"Speed and money are antithetical

to security and reliability...."

SRI International (Peter Neumann)

"What's more, at most colleges

teaching computer science,

techniques for developing secure code

are not even part of the required curriculum."


2. Fortify the ISP's

to filter out bogus packets

Cost and support issues


3. Make the Penalty Fit the Crime

Define the crimes

e.g., posting software that

could launch attacks as a crime

Define the penalties


4. Companies, Cover your XXXX

Install appropriate software and follow up

monitor it

back up data

update software

read bulletins


5. Teach your children well

computer ethics (driver education)

[Policing the Internet: Anyone But Government.

Steve Lohr, NY Times, 20 Feb 00, wk3]

"...[T]he F.T.C recently began investigating

how medical Web sites handle personal information.

And last week, DoubleClick, the Internet's

leading advertising placement company,

reported that the F.T.C. was investigating

how the company collected and used personal data."

"I find the profiling technology disturbing

--this notion of checking on consumer viewing

habits without them knowing it--especially

if that information is then merged with other

databases so they can be identified,"

said Robert Pitofsky, chairman of the F.T.C.
