Balancing Industrial Secure Remote Access: Essentiality and Risk Concerns

As industries continue to embrace digitalization and remote operations, industrial secure remote access has become an essential component of modern industrial automation systems. The ability to connect to and manage industrial assets remotely brings numerous benefits, such as increased operational efficiency and reduced downtime. However, alongside these advantages, there are growing concerns among firms regarding the associated risks and potential vulnerabilities.

A recent survey conducted by industry analysts sheds light on the concerns and perspectives of industrial organizations regarding secure remote access. According to the survey, 76% of respondents considered secure remote access to be critical for their operations. The ability to monitor, troubleshoot, and maintain industrial systems remotely enhances productivity and enables rapid response to operational issues.

Despite recognizing the importance of secure remote access, many firms express apprehension about the potential risks it poses. The survey reveals that 64% of respondents are concerned about unauthorized access and potential security breaches. Industries dealing with critical infrastructure, such as energy, manufacturing, and transportation, are particularly cautious due to the potential impact of a cyber attack on public safety, operational continuity, and financial stability.

To address these concerns, industrial organizations need to adopt comprehensive security measures and best practices for secure remote access. Firstly, implementing strong authentication protocols, such as multifactor authentication, can significantly reduce the risk of unauthorized access. Secondly, establishing secure virtual private network (VPN) connections and encrypted communication channels ensures data confidentiality and integrity during remote sessions.

Additionally, organizations must prioritize network segmentation to isolate critical industrial assets from the broader network. By implementing a defense-in-depth strategy, organizations can mitigate the impact of a security breach and prevent lateral movement within the network. Regular patching and updating of remote access software, firewalls, and security systems are also crucial to address emerging vulnerabilities and protecting against evolving threats.

Furthermore, employee education and awareness play a vital role in maintaining a secure remote access environment. Training programs can help employees recognize and report suspicious activities, understand the importance of strong passwords, and practice good cybersecurity hygiene. Organizations should also enforce strict access controls, granting remote access privileges only to authorized personnel with a legitimate need.

Industrial operations in the present era unquestionably require secure remote access. But businesses' worries about such risks and vulnerabilities must not be discounted. Organizations can strike a balance between the advantages and risks of remote access, ensuring the safety and integrity of their industrial systems in a world that is becoming more interconnected, by implementing strong security measures, adopting best practices, and fostering a culture of cybersecurity awareness.

Industrial Facilities are at Risk of Data Theft and Ransomware Attacks

 

Recently, multinational cybersecurity software company ‘Trend Micro’ has published a new report on cybersecurity in which it has highlighted the growing threats of downtime and sensitive credential theft from ransomware attacks targeting industrial facilities. 

“Industrial Control Systems are incredibly challenging to secure, leaving plenty of gaps in protection that threat actors are exploiting with growing determination,” said Ryan Flores, senior manager of forward-looking threat research for Trend Micro...” 

“…Given the US government is now treating ransomware attacks with the same gravity as terrorism, we hope our latest research will help industrial plant owners to prioritize and refocus their security efforts."

What happens when a threat actor targets your facility? 

In factories and other facilities, there are crucial elements of utility plants that help in monitoring and controlling industrial processes across IT-OT networks called Industrial Control Systems (ICS). However, in any case, when ransomware gets into these systems; it can stop all operations for several days and can heighten the risk of vulnerabilities. 

As per the published report, several different revised versions have been accounted for more than half of the ICS ransomware attacks in 2020 including Ryuk (20%), Nefilim (14.6%), Sodinokibi (13.5%), and LockBit (10.4%). 

Cybersecurity And Infrasture Agency (CISA) and the Multi-State Information Sharing and Analysis Center (MS-ISAC), jointly published a report titled ‘The Guide’, which aims at informing and enhancing network defense and reducing exposure to a ransomware attack. The two measures offered are Ransomware Prevention Best Practices and a Ransomware Response Checklist. Moreover, CISA provides various scanning and testing services to help organizations assess, identify and mitigate their exposure to threats, including ransomware, at no expense. 

The National Institute of Standards and Technology (NIST) also provides help against ransomware attacks. It offers help in detecting and responding. It is worth noting that lately, several cybersecurity agencies are coming forward for industries so that they can detect and mitigate future ransomware attacks and numerous guide reports are also being published on ransomware threats.
