As technology continues to advance, so do the risks associated with it. Operational and industrial networks are just as vulnerable to attack as any other network. While many companies focus on digital security measures, it is important to consider physical security measures as well. Physical equipment flaws may seem less concerning, but they can give hackers access to operational and industrial networks. Security directors should make sure to take necessary steps to mitigate these risks.
One of the most common physical equipment flaws that can lead to network vulnerabilities is outdated hardware. Older hardware generally has weaker security features and may not be compatible with newer security updates. It is important for security directors to regularly evaluate hardware and replace old equipment as needed to prevent weaknesses.
Another potential vulnerability is inadequate physical security measures. Physical access to equipment, such as servers or routers, should be carefully monitored and secured. Access should only be granted to authorized personnel with appropriate permissions. Poorly secured or unmonitored equipment can provide an attacker with a pathway into a network.
Physical flaws can also manifest in the software running on operational and industrial networks. Vulnerabilities in software or firmware can be exploited by attackers to gain control of equipment, such as PLCs or RTUs. Security directors should ensure that all software and firmware is kept up to date with the latest patches and security updates.
Failure to maintain proper power and environmental conditions can also lead to equipment failure or malfunction. Power surges or outages, as well as temperature fluctuations or water damage, can cause equipment to malfunction or fail altogether. Equipment failure can allow hackers to access a network. Security directors should make sure that equipment is maintained properly and is located in a secure environment.
While it may be easy to overlook physical equipment flaws as a potential vulnerability in operational and industrial networks, it is important to remember that every aspect of a network must be secured. Security directors should regularly evaluate hardware and software for vulnerabilities, monitor physical access to equipment, and ensure proper environmental conditions. By taking these necessary steps, companies can significantly reduce the risk of a breach through physical equipment flaws.
