The Center for Internet Security has updated its set of safeguards for warding off the five most common types of attacks facing enterprise networks—web-application hacking, insider and privilege misuse, malware, ransomware, and targeted intrusions.In issuing its CIS Controls V8 this month, the organization sought to present practical and specific actions businesses can take to protect their networks and data. These range from making an inventory of enterprise assets to account management to auditing logs.In part the new version was needed to address changes to how businesses operate since V7 was issued three years ago, and those changes guided the work. “Movement to cloud-based computing, virtualization, mobility, outsourcing, work-from-home, and changing attacker tactics have been central in every discussion,” the new controls document says.To read this article in full, please click here READ MORE HERE…

The Albuquerque water authority says recent network upgrades give it greater visibility and control over its remote sites and makes for faster responses to leaks and other problems.The Albuquerque Bernalillo County Water Utility Authority manages more than 3,000 miles of water-supply pipeline covering more than 650,000 users. The authority manages 135 remote locations, which include well sites, tanks, and pump stations, all of which have programmable logic controllers (PLC) connected to a dedicated, fixed-wireless network running at 900MHz back to the core network.[Get regularly scheduled insights by signing up for Network World newsletters.]
“The [main treatment] plant was built [about] 15 years ago,” said Kristen Sanders, the authority’s chief information security officer. “So if a piece of equipment went out, replacing it would be about shopping on eBay.” Also the authority’s fiber backbone that connects the sites with the main plant was past it’s service life and had to be replaced.To read this article in full, please click here READ MORE HERE…
