Update: Serial Server Flaws Expose Critical Infrastructure

A survey conducted by the firm Rapid 7 has found evidence that widespread vulnerabilities and insecure configuration of ubiquitous networking components known as serial port (or “terminal”) servers, may expose a wide range of companies and critical assets – including point of sale terminals, ATMs and industrial control systems – to remote cyber attacks.(*) The vulnerable devices connected hardware like retail point-of-sale systems at a national chain of dry cleaners, providing direct access to employee terminals from which customer payment information could be accessed. Other exposed systems were used to monitor the location of cargo containers, train cargo as well as HVAC and industrial control systems, Rapid7 said. In the Rapid7 survey, over 114,000 unique IPs were identified in a scan using the Simple Network Management Protocol (SNMP), the vast majority manufactured by one company: Digi International. If left unaddressed, the vulnerable devices give remote attackers direct, administrative access to hardware devices […]

Support Forums Reveal Soft Underbelly of Critical Infrastructure

We hear a lot about vulnerabilities in industrial control system (ICS) software. In fact, that’s all we seem to hear about these days. The truth is: there’s a lot to write about. In just the last month, the Department of Homeland Security’s ICS-CERT warned its members about the ability of  sophisticated – and even unskilled – attackers to use tools like the Shodan and ERIPP search engines to locate and attack vulnerable industrial control systems (PDF) that are accessible from the public Internet. In the meantime, every couple of weeks brings revelations about serious and remotely exploitable software holes. Most recently, ICS-CERT warned about a critical vulnerability EOScada (PDF), a Windows-based Energy Management System that is used to configure and manage intelligent electronic devices (IEDs) used in electrical, water, sewage and gas applications. But what about real evidence of compromised SCADA and industrial control systems? That’s a taller order. After all: most […]

Why digital certificates are critical to 5G security

As 5G gains traction, service providers need to be able to trust their networks’ security to truly take advantage of 5G’s capabilities. Digital certificates are critical to that, writes Alexa Tahan of Nokia.

Report: Major Upgrade, Investments Needed to Secure Connected Vehicles, Infrastructure

In-brief: a report by the Cloud Security Alliance calls for a bottom up remake of infrastructure to support connected vehicles and warns of more, serious attacks as connected vehicles begin interacting with each other and with connected – but insecure – infrastructure. 

Flying Dogs, Hackable Infrastructure and Other Tall Tales

In-brief: The headlines warning about cyber risks on the Internet of Things obscure the truth. That’s especially true of critical infrastructure, warns Cisco’s Marc Blackmer.
