Network access restrictions can limit the exposure of systems that have expired vendor support and lack an immediate replacement, as they can prevent unauthorized or unnecessary access to those systems from other devices or networks. Network access restrictions can include firewalls, network segmentation, VPNs, access control lists, and other methods that can filter or block traffic based on predefined rules or policies. Network access restrictions can reduce the security risks introduced by running systems that have expired vendor support, as they can mitigate the impact of potential vulnerabilities or exploits that may affect those systems.

Pseudo-anonymization is a technique of replacing sensitive data with artificial identifiers or pseudonyms that preserve some characteristics or attributes of the original data. It can protect employee data while allowing the companies to successfully share this information by removing direct identifiers such as names, addresses, etc., but retaining indirect identifiers such as job roles, pay scales, etc., that are relevant for the comparison.

Data entropy is a measure of the randomness or unpredictability of data. High data entropy means that the data has more variation and less repetition, making it harder to guess or crack. It can increase cryptographic security by making the encryption keys and ciphertext more complex and resistant to brute-force attacks, frequency analysis, etc

Testing the policy in a non-production environment before enabling the policy in the production network would prevent the issue of making several company servers unreachable. A non-production environment is a replica of the production network that is used for testing, development, or training purposes. By testing the policy in a non-production environment, the technician can verify the functionality and impact of the policy without affecting the real network or users. This can help to identify and resolve any errors or conflicts before applying the policy to the production network. Testing the policy in a non-production environment can also help to ensure compliance with security standards and best practices.

Archiving is the process of storing data for long-term preservation. In the context of IT security, archiving logs is the process of collecting and storing log files from devices in a centralized location. This allows organizations to access and analyze log data for troubleshooting, compliance, and security auditing purposes.

Log aggregation is the process of collecting log data from multiple sources and storing it in a single location. This can be done for performance or security reasons. However, log aggregation does not necessarily involve storing the logs in an off-site location.

DLP (Data Loss Prevention) is a set of technologies and processes that are used to protect sensitive data from unauthorized access, use, disclosure, alteration, or destruction. DLP can be used to prevent data from being exfiltrated from an organization's network, but it does not typically involve storing logs in an off-site location.

SCAP (Security Content Automation Protocol) is a set of standards and tools that are used to automate the assessment and remediation of security vulnerabilities. SCAP can be used to collect log data from devices, but it does not typically involve storing the logs in an off-site location.

Therefore, the best answer to the question is archiving.

Security information and event management (SIEM) is a solution that collects, analyzes, and correlates logs and events from various sources such as firewalls, servers, applications, etc., within an organization’s network. It can centralize logs to create a baseline and have visibility on security events by providing a unified dashboard and reporting system for log management and security monitoring.

A false positive is a type of alert that indicates a security incident when there is none. It can be caused by misconfigured or overly sensitive security tools or systems that generate false or irrelevant alerts. In this case, the alert from the company’s SIEM that Mimikatz attempted to run on the remote systems was a false positive because it was triggered by a legitimate vulnerability scanning tool that uses Mimikatz as part of its functionality.
