notably were the recent updates to the kernel. At the time of this writing,
only EnGarde and Red Hat have released updates to the “ioperm” system
call bug. It does not restrict privileges properly, which may result in a local
user being able to access the I/O ports on a system. In addition, an attacker
sending packets with a specially chosen forged source address can cause a large
number of collisions in the kernel’s networking hash tables, which results in
a denial of service.
co-editor. We discussed the changes
that will be made to the United States $20 bills to thwart counterfeiters.
Dave brought up the point that the US Federal Reserve is implementing some changes
that will not be made public. His thoughts were, “Would giving store clerks
and the general public more information to recognize a bogus bill help? Or would
releasing this information give too much to the counterfeiters and improve their
capabilities?” I found this discussion interesting because it has the same
underlying question as the security of open source software. Most people reading
this newsletter would probably agree that security can not be gained through
obscurity. What do you think?

of the Honeynet: Attacks, Tools, Incidents – Among other benefits,
running a honeynet makes one acutely aware about “what is going on” out there.
While placing a network IDS outside one’s firewall might also provide a similar
flood of alerts, a honeypot provides a unique prospective on what will be
going on when a related server is compromised used by the intruders.
