Cybersecurity and infrastructure security are closely related but distinct fields.
Cybersecurity refers to the protection of digital devices, networks, and data from unauthorized access, use, disclosure, disruption, modification, or destruction. It involves a wide range of technologies, processes, and practices that are used to safeguard sensitive information and prevent cyberattacks.
Infrastructure security, on the other hand, refers to the protection of critical infrastructure and systems that are vital to the functioning of society and the economy. This can include things like power grids, transportation systems, financial networks, and water supply systems. It involves identifying and mitigating risks to these systems and ensuring that they are resilient in the face of natural disasters, cyberattacks, or other disruptions.
The Cybersecurity and Infrastructure Security Agency (CISA) is a U.S. government agency that is responsible for protecting the nation’s critical infrastructure from physical and cyber threats. CISA works to improve the security and resilience of the nation’s infrastructure by providing guidance and assistance to infrastructure owners and operators, as well as coordinating with other government agencies and private sector partners.
