Cybersecurity For Public Utilities Solutions II
Cyberattacks launched on municipal utility companies are similar to attacks in any other industry. However, the potential for OT attacks and the dangers of a major service disruption has raised the stakes. Miller outlines in this article [1] the most common cybersecurity attacks that have affected municipal utility companies.
Denial of Service
Attacks that stop users from accessing essential networks are typically referred to as denial of service (DoS) or distributed denial of service (DDoS) attacks. A DoS attack is initiated by a single attacking computer. A DDoS attack is launched by multiple attacking devices. While the attack is in progress, companies can’t access the means to provide services. These attacks have serious implications for any company, but the interruption of essential services like electricity or running water can quickly become disastrous. Unfortunately, given the lack of training many utilities are particularly vulnerable to denial of service attacks. While these attacks are difficult to deal with, more work on raising an awareness of the issues and possible counter-measures would be invaluable.
