Windows TCP/IP Denial of Service Attacks (Sockstress)
(MS09-048, CVE-2008-4609, CVE-2009-1925, CVE-2009-1926)

Multiple vulnerabilities exist in the way Microsoft Windows processes TCP/IP connections. A remote attacker could exploit these vulnerabilities by sending specially crafted TCP/IP packets to an affected system. Successful exploitation of these vulnerabilities could allow the attacker to take complete control of the affected system or cause the affected system to become non-responsive. Check Point provides protections that detect and block attempts to exploit these TCP vulnerabilities though its IPS products.

Free SmartDefense 30 Day TrialBrowser SSL Certificates Vulnerability
(CVE-2009-2404, CVE-2009-2408)

A vulnerability in some browsers allows hackers to successfully impersonate SSL certificates of legitimate sites. If exploited, this vulnerability can allow a hacker to intercept sensitive transmissions. Check Point’s IPS products protect against this exploit by preventing the browser from treating these names with illegal characters as legitimate and will drop these connections.

Internet Information Services FTP Service Vulnerability

A remote code execution vulnerability has been discovered in Microsoft Internet Information Services (IIS). Successful exploitation of this vulnerability would allow the attacker to take complete control of the affected system. Exploit code is available in the wild. Check Point has 0-day protection available through its IPS products.

Best Practice: Boost IPS GUI Performance by Minimizing the Number of  Profiles
IPS profiles enable you to configure sets of protections for groups of gateways, providing both customization and efficiency. You can create up to 20 profiles. However, you should plan carefully before adding a new profile to the existing list of profiles. Keeping a concise number of profiles can improve your IPS GUI performance allowing you to deploy online updates and update protections in the protection browser faster.  Also, having fewer profiles makes the job of managing your IPS deployment simpler.

If you find you have profiles that you don’t want anymore, you can easily delete it. When deleting a profile make sure it does not reference other objects as this may affect gateways, other profiles, or SmartDashboard objects. You cannot delete the Default_Protection and Recommended_Protection profiles.

To Delete a Profile:
  • In the IPS tab, select Profiles.
  • Check for assigned Gateways.
    Before deleting a profile, you should make sure it is not currently in use. Right-click the profile and select Show Protected Gateways. If the list is empty then no gateway is assigned to this profile and it can be safely deleted.
  • Right-click the profile and select Delete.
  • Check for object references.
    If the profile contains references to or from other objects, the Object References window will appear, displaying all the objects that reference the profile and whether or not they are removable. If all the objects are removable, you can safely delete the profile.
