Denial of service

Description:

A Denial of Service (DoS) attack, is a type of attack whereby the perpetrator attempts to make a particular machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a specific host within a network. DoS attacks can occur when a system becomes flooded with specific network requests or subversive operations that can cause the resourced system to become unresponsive.

 

MITIGATION

 

This issue was validated by the product team engineers. A Symantec Encryption Desktop update, version SED 10.4.1MP2, has been released which addresses the aforementioned vulnerability. Note that the Symantec Encryption Desktop’s latest release and patches are available to customers through normal support channels. At this time, Symantec is not aware of any exploitations or adverse customer impact from these issues.

Best Practices

Symantec recommends the following measures to reduce risk of attack:

  • Restrict access to administrative or management systems to authorized privileged users.
  • 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.
