Sans today published its top 25 coding errors today, the full list can
be found here: http://news.bbc.co.uk/2/hi/technology/7824939.stm
Perhaps my OWASP involvement means I'm biased but do you feel that
another list of software coding flaws is required? I quickly (so pick me
up on errors!) marked the OWASP category I felt each Sans error falls
under and it did leave me to ask the question of why do we need another
list? We will now 3 main lists (again correct me if you feel I'm missing
anything) from OWASP, White Hat Sec and Sans respectively with each
lists content different to the others.
Does this give people guidance or does it bring confusion?
My quick mapping between Sans and OWASP (A1 - 10 represent the OWASP top
10 http://www.owasp.org/index.php/Top_10_2007) :
CWE-20:Improper Input Validation (A2)
