The Most Secure Networks Get Hacked Anyway, Study Says

Security analysts from both the firms FireEye and Mandiant have determined in a recent study that “97 percent” of networks, no matter how secure, “experienced some form of breach“, according to an article published on the Ars Technica website. The article indicates that the data mined from this study came from “more than 1,600 networks over a six-month period” that were heavily protected by “multiple layers of network and computer security software.”

According to the report, analysts placed “network and e-mail monitoring appliances” to collect data during the timeline between “October 2013 to March 2014.”  This data first showed FireEye and Mandiant, according to the article, that “three-quarters of the networks had command-and-control traffic indicating the presence of active security breaches connected to over 35,000 unique command-and-control servers.” The report clarifies that analysts extracted real-time data from “monitoring devices” which included “1,614 FireEye appliances that had been placed on networks as part of  ‘proof of value’ trials.”

The article indicates that all of the network environments sampled had a “defense in depth architecture“, which combines a number of security initiatives including “combined firewalls” along with “intrusion detection and prevention systems, and antivirus software.” Even though the environments were secured, the report says the devices were still able to identify “over 208,000 malware downloads across the monitored networks, of which 124,000 were unique malware variants.” As the article confirmed, analysts determined that each each network was “subjected to 1.6 exploits and 122 malware droppers during this six-month period.
