Firstly, organizations must proactively identify and address vulnerabilities in their systems. This involves staying updated on security advisories, regularly patching software, and having a process for reporting and fixing flaws discovered internally.
Secondly, protection from malicious code is crucial. This means implementing anti-virus, anti-malware, and other endpoint protection solutions on designated systems. These solutions should be configured to scan for and block threats on a continuous basis.
Thirdly, ongoing monitoring is essential. Organizations need to have systems in place to detect suspicious activity and security alerts. This might involve log analysis tools, intrusion detection systems, or security information and event management (SIEM) solutions. When an alert is triggered, it's vital to investigate and take appropriate action.
Finally, keeping security software up-to-date is critical. This includes applying the latest patches and updates to anti-malware and other security tools as soon as they become available. By following these NIST 800-171 requirements, organizations can significantly reduce the risk of unauthorized data modification and ensure the integrity of their systems and information.
