The European Network and Information Security Agency (ENISA) issued a 150 page report, Botnets: Measurement, Detection, Disinfection, and Defence, released March 7 pointing out inherent flaws in current methods for measuring the size and scope of botnets. Botnet size measurements are not uniform across the security industry and, beyond that, lack a strong scientific basis, according to the report. Modern botnet metrics are constantly evolving and serve varied purposes, the report argues. The report is optimistic that closer international cooperation between EU governments and technically-oriented legislative bodies, along with the cooperation of stakeholders, can vastly improve efforts to fight botnets and arrest the criminals who operate them.
