- Restrict remote access to trusted/authorized systems only.
- Run under the principle of least privilege, where possible, to limit the impact of potential exploit.
- Keep all operating systems and applications current with vendor patches.
- Follow a multi-layered approach to security. At a minimum, run both firewall and anti-malware applications to provide multiple points of detection and protection for both inbound and outbound threats.
- Deploy network and host-based intrusion detection systems to monitor network traffic for signs of anomalous or suspicious activity. This may aid in the detection of attacks or malicious activity related to the exploitation of latent vulnerabilities.
