Cyberattacks on financial institutions are growing more frequent, persistent and dangerous and could threaten the interconnected global financial system, according to the world’s largest industrial nations. The Group of Seven governments published a common set of cybersecurity guidelines and principles Tuesday in an effort to reduce the threat. The G-7 nations are Britain, Canada, France, Germany, Italy, Japan and the United States. The guidelines urge governments, banks, regulators and others to use the outline to craft a strategy appropriate for each institution. The strategy is to share and use best practices to assess and monitor cyberattacks and make plans to respond to intrusions and block the theft of money or information. The guidelines call on G-7 members to share information and lessons learned so cyber defenses are dynamic and systems are continuously learning. The hope is that most attacks will be stopped, and intrusions will be cut short and systems returned to service promptly. The document says trust and confidence in the financial sector improves when financial instructions and nations can have the ability to assist each other. Cyber thieves have targeted large financial institutions around the world, including America's largest bank JPMorgan, as well as smaller players like Ecuador's Banco del Austro and Vietnam's Tien Phong Bank, both Reuters and The Wall Street Journal have reported. The U.S. Federal Reserve's internal security staff detected more than 50 cyber breaches between 2011 and 2015.
