Which framework was improved by NIST in 1995 to include cybersecurity?

The NIST Cybersecurity Framework is indeed the correct answer because it was specifically developed to address the growing need for effective cybersecurity management. This framework emerged from an initiative that began in 2013 but builds upon prior work and guidance provided by NIST in earlier years, including updates that align with evolving cybersecurity threats and solutions.

NIST has been a leader in standardizing practices, and the advancements made to the Cybersecurity Framework over the years reflect the organization's commitment to improving national security in relation to cybersecurity risks. The framework offers guidelines for organizations to enhance their cybersecurity posture by identifying, protecting against, detecting, responding to, and recovering from cyber incidents.

In contrast, while NIST SP 800-53 does provide security controls that include aspects of cybersecurity, it is one of several publications under the NIST SP 800 series focused on information security. The NIST Risk Management Framework provides a process for managing information security risk, and the NIST Privacy Framework focuses specifically on privacy risk management. These frameworks serve different purposes within the broader context of cybersecurity and information governance, but the NIST Cybersecurity Framework explicitly addresses the core functions needed to bolster cybersecurity practices.
