An analysis of a National Institute of Standards and Technology initiative to identify algorithms that could defend encryption against attacks from quantum computers leads the latest edition of the ISMG Security Report. Also featured: An update on new FDA guidance on cybersecurity for medical devices.
Now that more breaches are targeting industrial control systems, organizations that have paid little attention to operational technology security must ramp up their protection efforts, says breach response expert Christopher Novak of Verizon.
Will more "historical" breaches be revealed in 2017 and beyond? Data breach expert Troy Hunt is optimistic that such revelations will become rare as large businesses operating online continue to improve security. But what about small and mid-size organizations?
With the rise of malware infecting IoT devices, DDoS defenders "have to assume that the attackers have an unlimited supply of machines that they can compromise," says Akamai's Michael Smith. But quarantines, ISP feedback loops and better patch management can bolster defenses.
