Detecting cyber intrusions in the digital substation

Let us define a cyber-attack on a substation as an event where an adversary modifies, degrades, or disables a service of at least one protection, automation, or control device within the substation. Looking at Figure 1, a typical substation can be attacked through all paths marked with a number. An attacker could enter through the control center connection (1), as it happened in one of th... More

Personal Privacy - (data privacy - personal data)

The Merriam-Webster dictionary defines privacy as freedom from unauthorized intrusion. However, if one was to delve into a more philosophical examination of the concept of privacy, we come to realize that the fundamental idea of privacy is so sacred, that in essence it encompasses what it means to be an individual.  When we engage in social interaction we carefully choose how much abo... More
