Abstract

In recent years, SCADA has been integrated into power systems to achieve automation at many phases, including generation, transmission, and distribution. This process makes the Smart Grid better in a big way. However, the excessive integration of SCADA systems into the Smart Grid comes at the expense of cyberattacks, which can result in significant losses in terms of money, confidence, and even lives. In the past, these cyberattacks with ransom demands led to prolonged blackouts in places like the Ukraine, Natanz, Mumbai, the United States, etc. Therefore, ensuring an uninterrupted power supply for the consumers and defending the entire Smart Grid System from these kinds of attacks are the essential tasks. Confidentiality, Integrity, and Availability (CIA) of the sensitive information that is being transported between the two end terminals, from the sensors to the Substation, can be taken care of in order to protect it. The Cyber Security Management System (CSMS) is the suggested remedy for this, and it contains the remediation steps to be taken after an attack (to get back to the fully functional state), protocols to be followed, standards for the hardware and software to be maintained, and instructions on how to deal with updates, security patches, and zero-day attacks, among other things. Along with these safeguards, other attacks, including DDoS (Distributed Denial of Service), CSRF (Cross-Site Request Forgery), XSS (Cross-Site Scripting), and MITM(Man in the Middle), Spoofing, Tampering, Ransomware and others are discussed in this paper.
