The new federal computer security report card is out, and once again the
grades are pretty bad. And once again it is hard to say just what they
really mean.
The report card is issued each year by Virginia Rep. Tom Davis, ranking
Republican on the House Government Oversight and Reform Committee. Davis
gave the 24 executive branch agencies covered in the report an overall
grade of C- for 2006, a grade he said showed slow but steady improvement
from past years.
"Slow" is right, but I dont know how much improvement there is or how
steady it has been. The grade had been stalled at D or D+ for the
previous three years. Agencies receiving an F or an A this year are tied
at eight each. Seven agencies improved their grades this year, six got
worse and 10 remained the same. One major department, Veterans Affairs,
didnt bother to provide a report for 2006 and so receives an incomplete.
But the biggest challenge is determining just what the grades are
measuring. The report card bills them as federal computer security
grades, but they are primarily based on compliance with the Federal
Information Security Management Act. As I have said before, FISMA does
not equal security. FISMA does not require secure IT systems; it
requires a process for assessing, testing and managing IT security.
Davis grades are based largely on how good a job an agency is doing at
inventorying, testing, certifying and accrediting its IT systems. It
would be possible to test, certify and accredit all your systems and get
a splendid grade even if your systems failed the tests and you were
accrediting them despite their vulnerabilities.
That is not to say that agencies are doing this. Good FISMA compliance
should enable an IT shop to improve its security posture. But we really
dont know from the report card whether or not it is helping. Is it
really reasonable to believe that Housing and Urban Development improved
its security from a D+ to an A+ in one year, or that Justice can go from
a D to an A-? Or that NASA could drop from a B- to a D-? Thats what this
years grades show, and I have a hard time believing it.
FISMA can be a powerful tool for improving federal IT security, and the
annual report card has done a good job in helping to focus attention on
this subject. But Im not sure just what the grades are measuring. I
suspect it is not computer security and maybe not even FISMA
performance.
A group made up of IT security vendors called the Merlin International
Federal Research Consortium, surveyed federal chief information security
officers about FISMA in advance of the report card. The results should
probably be taken with a grain of salt only 30 of 117 CISOs
participated, and 75 percent of the respondents said their FISMA grades
were going to improve this year, so it probably wasnt a representative
sample. But a couple of good ideas did come out of the report.
By a wide margin, the two greatest problems cited in FISMA compliance
were funding and ambiguity in the way FISMA requirements are written.
When asked for suggestions on how to improve the act, the CISOs didnt
say anything about funding for security. They apparently do not think
that is ever going to happen. But they did say that there should be
better guidance to agencies for the yearly security controls tests and
that FISMA guidelines should be clarified.
Maybe these two simple improvements could result in some real progress
in both FISMA compliance and IT security.
