CISA stands for “Cybersecurity and Infrastructure Security Agency.” CISA is a United States government agency responsible for protecting the nation’s critical infrastructure from cyber threats and physical attacks. The agency was established in November 2018, as part of the Department of Homeland Security (DHS), and is tasked with coordinating with other federal, state, local, and private sector entities to manage and respond to cybersecurity and infrastructure security risks. CISA’s responsibilities include sharing threat intelligence and providing guidance on best practices for cybersecurity and critical infrastructure protection, as well as responding to and investigating cybersecurity incidents and promoting resilience in the face of emerging threats.

Infosec is an abbreviation for “information security,” which refers to the practice of protecting digital information, such as electronic data, systems, and networks, from unauthorized access, use, disclosure, disruption, modification, or destruction. Infosec involves a range of strategies, technologies, and best practices to safeguard data and ensure the confidentiality, integrity, and availability of information. Common infosec measures include access control, authentication, encryption, firewalls, intrusion detection and prevention systems, security assessments, and incident response planning. In today’s world where digital information is a valuable asset, infosec is essential for organizations and individuals to maintain the privacy and security of their information.
