The National Security Agency (NSA) has published two cybersecurity information sheets (CSIs) with recommendations for National Security System (NSS) and Department of Defense (DoD) workers and system administrators on securing networks and responding to incidents during the work-from-home period.
Titled Compromised Personal Network Indicators and Mitigations, the first of the CSIs is meant to deliver details on how teleworkers can identify and mitigate the compromise of their personal networks and to secure data and the equipment provided by the government when working remotely.
Furthermore, the CSI provides a series of indicators of compromise (IoC), along with the mitigation techniques that teleworkers can apply to prevent future compromises. The CSI is meant for government employees, but anyone can use the provided information to identify and prevent network breaches, the NSA points out.
“While there is no way to ensure that personal networks will be completely secured from attacks—attackers are persistent and continue to find ways to circumvent security controls—users can still take steps to help prevent future attacks,” the CSI reads.
Should the indicators of compromise outlined in the document be observed, users are advised to apply the provided mitigations to any computer, mobile device, or IoT device connected to their personal network.
Recommended steps to mitigate the compromise, the NSA says, include rebooting and resetting routers, disabling their remote administration functionality and updating the firmware; disconnecting infected machines from the network, resetting passwords on a different device and running anti-malware software; and removing ransomware infections and rest ..
