Which practice helps to enhance the overall security posture of an organization?

Regular software updates and patches are critical in enhancing the overall security posture of an organization. By keeping software up to date, organizations can protect themselves against known vulnerabilities that cybercriminals may exploit. Software vendors often release updates and patches specifically to fix security flaws, ensuring that the systems running on an organization's network remain secure against the latest threats.

Outdated software can serve as an easy target for attackers, as they often look for unpatched vulnerabilities to gain unauthorized access to systems, data, or networks. By routinely updating software, organizations effectively mitigate risks related to exploitation of these vulnerabilities, thereby strengthening their defenses and overall security posture.

The other options, such as storing credentials in plain text, sharing passwords among team members, and minimizing data access control, lead to increased risk and insecure practices. Each of those practices compromises the integrity and confidentiality of sensitive information, making it vital to focus on strategies like regular updates and patches to ensure a robust security framework.
