Cybersecurity 'Massively disruptive' cyber crisis engulfs multiple agencies. Cybersecurity is the protection of internet-connected systems such as hardware, software and data from cyber-threats. Also referred to as information security, cybersecurity refers to the practice of ensuring the integrity, confidentiality, and availability (ICA) of information. Pursuant to Presidential Policy Directive (PPD) 41, the FBI, CISA, and ODNI have formed a Cyber Unified Coordination Group (UCG) to coordinate a whole-of-government response to this significant cyber incident. Cyber security may also be referred to as information technology security. Over the course of the past several days, the FBI, CISA, and ODNI have become aware of a significant and ongoing cybersecurity campaign. What is cybersecurity? Definition of cybersecurity. And when CISA followed up with an updated cyber alert on Dec. 17, the agencies had yet to begin to fully realize the depth and breadth of the attack. A limitless cyberspace, zero boundaries and eroding national borders is just the beginning of cyber threats. After the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (CISA) released an emergency directive on Dec. 13, the race was on to detect, mitigate and respond. Cybersecurity is the art of protecting networks, devices, and data from unauthorized access or criminal use and the practice of ensuring confidentiality, integrity, and availability of information. Information security (InfoSec), or data security, is a chief component of cybersecurity and entails ensuring the confidentiality, integrity, and availability of data. As cyber-attacks and data breaches have become increasingly common, better-secured networks and IT infrastructure are required to ensure the safety of sensitive information. Cybersecurity refers to the practice of reducing cyber risk through the protection of the entire information technology (IT) infrastructure, including systems, applications, hardware, software, and data. The Importance of Cyber Security. Cybersecurity is comprised of an evolving set of tools, risk management approaches, technologies, training, and best practices designed to protect networks, devices, programs, and data from attacks or unauthorized access. The full-length, Cybersecurity Professional Program offers students the knowledge transfer and theory in addition to the hands-on training crucial to building an impressive, cyber skill set. Cyber security is important because government, military, corporate, financial, and medical organizations collect, process, and store unprecedented amounts of data on computers and other devices.
