According to the latest published research by Kaspersky about industrial cyber security, a wide majority of surveyed organizations have expressed concerns about OT (operational technology) security. However, only one-third of the survey respondents have deployed some degrees of OT security. Such findings have clearly revealed the vulnerability of utility-generating and mission critical organizations. Apparently, with such level of protection, any deliberate attack like DDoS would devastate a country’s supply of electricity, water, petroleum or gas. In short, the OT asset management remains a challenge for ICS (industrial control system) and SCADA owners and is apparently vulnerable.
