How Can Organizations Secure Their SCADA Systems?

Recent years have seen an increase in the size and frequency of cyberattacks on SCADA systems. Organizations must adhere to best practices when it comes to safeguarding their SCADA systems.

Fremont, CA: Working in industries such as oil and gas or utilities, there is a good probability that one will come across a SCADA system on the job. These systems are vital for monitoring and controlling various pieces of equipment designed to deal with time-sensitive and critical events. While there are numerous types of SCADA software, each one has several common qualities. Whether an individual owns an industrial business or is key management at one, they are likely to be interested in learning more about SCADA systems and how they work. While this software is intended to function in the background, it is possible for an issue to arise, so it is critical to understand what SCADA is and how it works.

How to secure SCADA systems?

As with any type of software, the SCADA system's security can be compromised if it is not robust enough to withstand various cyber threats. The majority of this software has been designed to maximize efficiency, which means that its security is typically lacking. Regardless of the size of the SCADA network, it is critical for an organization to increase the system's security.

The organization must begin by identifying all of its SCADA network's connections. Once these connections have been identified, a risk analysis should be conducted to ascertain the necessity of each connection. Disconnect any connections that are not deemed necessary. They should verify dial-up connections, internet connections, wide area or local networks, vendor and business partner connections, and wireless network devices. Additionally, they can determine the security of each connection by performing a vulnerability analysis on all remaining networks. It is recommended that less secure networks implement intrusion detection systems and firewalls at all points of entry.

Additionally, a business can strengthen security by establishing a team capable of identifying and evaluating potential attacks and system vulnerabilities, conducting regular technical audits to highlight security concerns, and establishing 24/7 incident monitoring. Their system administrators, managers, and other SCADA system users should all be aware of their respective roles and responsibilities in terms of system security. If a cyber-attack occurs, it is critical to have system backups and recovery plans in place to ensure rapid recovery. By strengthening the system's security and establishing a strong cyber security team, a business should be able to mitigate the inherent risks associated with SCADA use.
