this vulnerability. The signature, HTTP Backup Exec Sys Recovery Dir Trav, is
available in signatures dated 05/28/2008 and later.
Best Practices
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
