In today's cyber threat environment, attackers and defenders are constantly trying to outmaneuver each other and the stakes are higher than ever, particularly for mission-critical systems and communications. Understanding the methods and motivations of threat actors is crucial to developing a proactive program to defend against and prevent future attacks. In part one of our four part webinar series, we will introduce our insights and analysis of the most significant and impactful cyber threats facing public safety organizations. In our review of the 2022 landscape, we will breakdown the drivers of the threat actors seeking to profit or cripple mission critical systems, while introducing how we seek to combat these threats with collaboration and intelligence sharing through the Public Safety Threat Alliance (PSTA). We will also share details about the PSTAs free membership for public safety agencies, and how they can join this critical information sharing community today and begin improving their cybersecurity posture against cyber threats to their critical systems.
