Legacy System: A legacy system is an outdated computing system or application that is still in use despite being surpassed by newer technologies. These systems often lack support and modern security features, making them vulnerable to cyber threats. Security strategies for legacy systems may include isolated environments, stringent access controls, and regular risk assessments until they can be safely upgraded or replaced.
