Security incidents rise in industrial control systems

.....A new report based on data gathered by the Repository of Industrial Security Incidents (RISI) database provides a rare look at trends in malware infections, hacks, and insider attacks within these traditionally cloistered operations. Cybersecurity incidents in petroleum and petrochemical control systems have declined significantly over the past five years — down more than 80 percent — but water and wastewater have increased 300 percent, and power/utilities by 30 percent, according to the 2009 Annual Report on Cyber Security Incidents and Trends Affecting Industrial Control Systems. source: http://www.darkreading.com/insiderthreat/security/attacks/showArticle.jhtml?articleID=224400280
