Worldwide Infrastructure Security Report 2009 from Arbor released

[Juha-Matti Laurio <juha-matti.laurio () netti fi>]

"The largest reported volumetric DDoS attack this cycle exceeded 49 Gbps sustained towards a single target, reported by 
a ‘large’ ISP in Europe. 
Beyond sheer attack size, respondents indicated that they are continuing to see attacks become more sophisticated,
with attackers expressly aiming to exhaust resources other than bandwidth, such as firewalls, load-balancers,
back-end database infrastructure and associated transaction capacity, cached data serving algorithms, etc.
This increasing sophistication is a disconcerting trend that has been captured in previous editions of the survey as 
well, and one that continues to worry network operators."
