NIST.SP.800-82r2.pdf

The document offers guidance on managing security patches and vulnerabilities in organizational IT systems, with a focus on industrial control systems (ICS). It stresses the importance of testing patches in ICS environments to mitigate risks and avoid adverse effects. Emphasis is placed on establishing a systematic ICS patch management process and the recommendation to automate patch deployment. Program management controls, privacy controls for safeguarding personally identifiable information (PII), and the alignment of eight privacy control families with Fair Information Practice Principles (FIPPs) are discussed. The document also mentions NIST SP 800-53 and its Privacy Appendix for structured privacy controls based on international standards. The ICS overlay tailors controls from SP 800-53, Revision 4, to offer specific guidance for ICS systems across various industrial sectors.
