US Agencies Issue Cybersecurity Guidance Against China-Linked Threats

In a collaborative effort, the National Security Agency (NSA), the FBI, and the Cybersecurity and Infrastructure Security Agency (CISA) have joined forces with their counterparts from Australia, Canada, and New Zealand to release a robust cybersecurity guidance aimed at thwarting threats from China-linked malicious actors. The guidance, titled “Enhanced Visibility and Hardening Guidance for Communications Infrastructure”, emphasizes proactive measures to secure telecommunications and enterprise networks.

This nine-page document outlines critical strategies for improving network visibility, such as tracking configuration changes and monitoring unusual activity, as well as detailed steps for hardening network systems. Key recommendations include regular patching, enforcing secure password practices, and disabling unused or insecure protocols. Notably, the guidance addresses specific vulnerabilities in Cisco operating systems, which have been targeted by China-affiliated threat groups in the past.

Proactive Defense Measures

According to NSA cybersecurity director Dave Luber, vigilance and early action are crucial in network defense. “Always have eyes on your systems and patch and address known vulnerabilities before they become targets,” Luber stated. Organizations are urged to log all network activity and adopt strong security measures to mitigate risks.

While primarily aimed at telecommunications providers, the guidance also holds value for enterprises managing on-premises infrastructure. By implementing these measures, organizations can bolster their defenses against increasingly sophisticated cyber threats.

Global Collaboration in Cybersecurity

This initiative exemplifies the growing global collaboration among allied nations to address cybersecurity challenges posed by state-sponsored threats. The partnership among the Five Eyes nations (United States, Australia, Canada, New Zealand, and the United Kingdom) underscores the shared responsibility of safeguarding critical infrastructure against cyber adversaries.
