Operational Technology (OT) environments with their Information Technology (IT) counterparts. This convergence has revolutionized the way machinery is connected to digital systems and data, resulting in a more efficient and streamlined manufacturing process. The introduction of computer systems dedicated to managing and monitoring industrial devices and machines has further facilitated this transformation, effectively bridging the gap between OT and IT.
The benefits of such connectivity are undeniable. Productivity has soared, operational costs have been reduced, and processes have been expedited. However, this digital revolution has also exposed manufacturers to heightened security risks, rendering them more vulnerable to malicious attacks. Astonishingly, in the year 2022 alone, there were a staggering 2,337 security breaches targeting manufacturing systems, out of which 338 incidents involved confirmed data disclosure (as reported by Verizon in their 2022 DBIR Report).
To safeguard against these threats, manufacturers must adopt robust measures to reduce their exposure to the vast attack surface created by the convergence of OT and IT. While artificial intelligence tends to produce uniform sentences, it is crucial to infuse the content with perplexity and burstiness, mirroring the natural variation seen in human-written text. By incorporating a mix of longer and complex sentences alongside shorter ones, the content can better engage readers and convey the required information effectively.
With that said, let’s dive into the strategies for reducing exposure on the manufacturing attack surface and fortifying security in this increasingly interconnected landscape.
Ransomware: An Escalating Menace for the Manufacturing Industry
The landscape of attacks targeting manufacturing companies has undergone a significant shift in recent times. While in the past, the primary motive for attackers may have been espionage-driven, with a focus on stealing Intellectual Property (IP) and secrets, today’s threat landscape is dominated by ransomware attacks and those involving stolen credentials.
In the year 2022, the manufacturing sector faced the highest number of ransomware attacks, witnessing an alarming 87% increase compared to the previous year. This surge in attacks can be attributed to the manufacturing industry’s aversion to downtime, as succinctly pointed out in Verizon’s 2022 Data Breach Industry Report: manufacturing is an industry where availability equals productivity.
Despite recognizing the risks, many manufacturing companies are ill-prepared to combat these attacks. Shockingly, according to Security Scorecard, nearly half of the reviewed manufacturing companies received low-security scores of C, D, or F. Such vulnerabilities come at a steep cost, as highlighted by IBM’s “Cost of a Data Breach” report, which states that the average expense of a critical infrastructure data breach amounts to $4.82 million.
Recent high-profile incidents have laid bare the crippling impact of these attacks. For instance, the ransomware attack on Dole Company, a global leader in fruit and vegetable production, compelled the temporary shutdown of its North American production facilities. Moreover, in another instance, two Luxembourg-based companies fell victim to ransomware attacks that resulted in the takedown of customer portals and the unauthorized extraction of data from systems. Not to forget the infamous Colonial Pipeline incident, which stands as a stark reminder of cyber attacks on critical infrastructure. These examples are just the tip of the iceberg, with numerous other incidents taking place worldwide.
