How to Worry About Linux Security
(Linux Journal 8/28/06)

“Worry about a networked system is good,
the trick is to worry about the right things &
to act on our worries”

Folks you should worry about

Weapons you should worry about

Vulnerabilities You Should Worry About

How to channel worries into constructive
action
Folks You Should Worry About

Mostly work you way outward, but
once in awhile look from cracker's
viewpoint




Identity Thieves Resource Thieves
Malicious Code
Vandals
Corporate Spies Stalkers
Not all crackers are remote: INSIDERS
Weapons You Should Worry About

Mid 90's weapon was cracker at PC
(or)



Direct interaction: attacker – victim
Usually correct, sometimes not
Today vast majority are automated


viruses, trojans and worms
botnet:



spammers paid per distribution node
DdoSers, Phishers
Crackers still here but most are “script kiddies”
Vulnerabilities
You Should Worry About

a threat equals an attacker plus some
vulnerability


If a vulnerability cannot be exploited it
does not constitute a risk
No such thing as a completely
invulnerable system but can lower %
Common types of vulnerabilities




Bugs in user-space software (applications)
Bugs in system software
(kernel, drivers/modules, etc.)
Extraneous user accounts
Extraneous software
(with bugs or sloppy/default settings)

Unused security features in applications

Unused security features in the OS

Gullible users
Recipe
to convert worry to action
1. Define system function
Sun Tzu: analyze terrain you need to defend
2. Prioritize types of attacks most likely
3. What data/resources most likely target
4. What vulnerabilities give access to #3
5. How can I lower/remove vulnerability

“The security architecture of an
information system is fundamental to
enforcing an organization’s
information security policy.”
Ch 6 :

media used, and over the operators
using these resources.”
