Leader in ICS cybersecurity examines the correlation between the current Industrial Revolution and increased cyber risk in new whitepaper

Maintaining the integrity of the world’s critical infrastructure depends on industry recognizing risk and better protecting every aspect of industrial control systems that make them vulnerable to cyber attack.

NexDefense Inc., a leading provider of cybersecurity for industrial control systems (ICS), today announced the release of its newest whitepaper, “The ICS Threat Landscape: Why Industry Cannot Neglect ICS Network Infrastructure Anymore.” The whitepaper is available for free download by visiting:

Historically isolated, both physically and virtually, ICS that operate critical infrastructures (e.g. power, water, chemical & refining, transportation, manufacturing and a host of other essential sectors) were designed to last for upwards of two decades and independently perform the same function for the entirety of their lifecycles. With safety and reliability traditionally the top two priorities, the majority of resources were given to the personnel who needed to fulfill the 24/7/365 productivity objectives. In doing so, little thought was given to ICS network infrastructure, because the networks were simple and straightforward.

In the past five to 10 years, the proliferation of inclusive connectivity in ICS environments has outpaced the changes to design and operations. As a result, many critical infrastructure organizations haven’t fully kept pace with the rate and significance of changes to their systems, and vulnerabilities have emerged that are highly available to exploit.

In this whitepaper, NexDefense explains:

  •     How linking legacy ICS systems with modern IT technology is both a blessing and a curse;
  •     Why “air gaps” between internal ICS networks and remote systems can backfire;
  •     How Sophia can detect potential threats that attempt to disrupt your control systems.

“Adversaries are exploiting vulnerabilities within industrial control systems that are often the result of years, if not decades, of network neglect,” said Doug Wylie, vice president of product marketing at NexDefense. “As convergence continues across all critical infrastructure sectors, owners and operators must understand that cyber threats will continue to increase so long as adversaries have the means, motives and opportunities (MMO) to launch meaningful attacks. Continuing to neglect ICS networks is one way to ensure that MMO will increase.”

NexDefense helps organizations across critical infrastructure sectors to identify threats, reduce risks and better maintain the availability, integrity and confidentiality of all essential operations. Sophia™, the company’s patent-pending Industrial Network Security Monitoring system, is a cybersecurity solution purpose-built for control systems to enhance protection while also facilitating compliance to standards and best practices. Sophia understands ICS protocols and provides real-time insight into systems to give organizations visibility and access to the data they need to know to make real-time decisions and better protect critical infrastructure from cyber attacks.

“Maintaining the integrity of the world’s critical infrastructure depends on industry recognizing risk and better protecting every aspect of industrial control systems that make them vulnerable to cyber attack,” said Bryan Singer, principal investigator with Kenexis and NexDefense Fellow. “This white paper examines what owners and operators need to know in order to safeguard their networks from the increasing risks and exposure to threats that come with convergence, the Industrial Internet of Things (IIoT) and the complicated predicament of a hyper-connected enterprise.”
