As for prevention, there are really just three main strategies to protect against these attacks:

1. User Education and Awareness: A large percentage of APT attacks begin with spear-phishing or other forms of social engineering. Regularly training employees to recognize such attempts can significantly reduce the risk of an initial breach.

2. Regular Patching and Updates: Many APTs exploit known vulnerabilities in software that have not been patched. Keeping all systems updated with the latest patches significantly reduces the attack surface.

3. Advanced Threat Detection and Response: Implement a robust cybersecurity infrastructure that includes firewalls, intrusion detection systems (IDS), intrusion prevention systems (IPS), and endpoint protection platforms (EPP). Regularly monitor and analyze logs for suspicious activity. Also, consider employing a Security Information and Event Management (SIEM) system to correlate and analyze security alerts from different sources in real-time.

Remember, no solution is 100% foolproof, and the aim should always be to reduce risk and increase your organization's ability to respond effectively if a breach does occur.
