What is one factor that may increase the risk of a data breach in registries?

Outdated software or systems lacking proper security updates significantly increase the risk of a data breach in registries because these vulnerabilities can be easily exploited by cybercriminals. When software or systems are not regularly updated, they do not receive patches that fix known security flaws, leaving them open to attacks. This can include exploits that take advantage of weaknesses in the code or new methods of attack that have been developed since the software was last updated. In contrast, regular software updates, continuous employee training, and strong password policies are all proactive measures to enhance security and reduce the likelihood of a data breach. Therefore, failing to maintain up-to-date software represents a critical security vulnerability.
