Last year, WashU Information Security Office (ISO) purchased a new security service that recently prevented campus users from being affected by a critical threat in an unforeseen way.
The service, called OpenDNS, was designed to protect the University from known threats such as malware, spyware, adware, and phishing sites. Users only experience the impact of OpenDNS when they are redirected to a “blocked site” message when their device attempts to visit a website the service deems potentially malicious.
Thanks to OpenDNS, University users were also recently protected from a potentially widespread dangerous flaw that exposed devices around the world to malicious attacks. On Feb. 17, Google researchers announced they had discovered a critical flaw in a C library widely used in Linux systems.
Though the flaw left Linux system apps and hardware devices everywhere vulnerable to attacks, WashU apps and hardware were protected thanks to the OpenDNS service
OpenDNS , a company founded by WashU alum David Ulevitch, provides cloud-delivered network security services that protect devices from known and emergent threats such as malware, spyware, adware and phishing sites. OpenDNS is available to everyone who accesses the Internet via the WashU Infoblox DNS servers by default. Learn more about OpenDNS here.
