Adversarial advantage: Using nation-state threat analysis to strengthen U.S. cybersecurity
- Nation-state attackers are changing their approach, pivoting from data destruction to prioritizing stealth and espionage, as they pose a critical threat to United States infrastructure and protected data.
- Thankfully, there’s an upside to these malicious efforts: information. By analyzing nation-state tactics, government agencies and private enterprises are better prepared to track, manage and mitigate these attacks.
- The Cybersecurity & Infrastructure Security Agency (CISA) identifies four prolific nation-state actors: The Chinese government, the Russian government, the North Korean government and the Iranian government.
- According to CISA’s associate director for threat hunting, Jermaine Roebuck, these actors use various methods to compromise security and gain access to victim networks. These include phishing, use of stolen credentials and exploiting unpatched vulnerabilities and/or security misconfigurations.
- By understanding the techniques and tactics used by threat actors, organizations are better prepared to allocate limited security resources where they will be most effective.
- While the actions of each nation-state offer protective insight for American cybersecurity, there’s another component in effective defense: getting back to basics. These approaches aren’t mutually exclusive, as government agencies need to identify and dismantle disinformation campaigns.
- Other CISA recommendations include implementing strong authentication, regularly updating and patching systems, educating employees on recognizing phishing attempts, and using antivirus and anti-malware solutions.
- Roebuck also recommends that businesses establish centralized log management and regularly review these logs for suspicious activity.
- Remote access has become commonplace as organizations embrace the need for agile operations. By using secure configurations for remote services and limiting access to trusted IP addresses, enterprises can minimize remote access risks.
- Ultimately, Roebuck’s security advice is straightforward: “To protect against the increased prevalence of malicious actors, implement and maintain an effective solution to detect intrusions and evict attackers as quickly as possible.“
