Symantec recommends the following best practices when using remote access applications:

*Corporate firewalls should not allow inbound or outbound access without using VPN tunnels.
*When configuring a remote access application, establish policies around password strength, password retry limits
*Always configure the application to require the user to approve all remote connections

As part of normal best practices, Symantec strongly recommends:

*Restrict access to administration or management systems to privileged users
*Restrict remote access, if required, to trusted/authorized systems only
*Run under the principle of least privilege where possible to limit the impact of exploit by threats
*Keep all operating systems and applications updated with the latest vendor patches
*Follow a multi-layered approach to security. Run both firewall and anti-malware applications, at a minimum, to provide multiple points of detection and protection to 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 detection of attacks or malicious activity related to exploitation of latent vulnerabilities
