Cisco announced late on Monday that it is investigating reports of the National Security Agency infiltrating the company's technologies.
The investigation comes after Der Speigel reported earlier in the week that the NSA “has burrowed its way into nearly all the security architecture made by the major players" in the computer network industry, including Cisco.
“If we learn of a security weakness in any of our products, we will immediately address it,” Cisco chief security officer John Stewart wrote in a blog post initially published Sunday.
On Monday, Der Speigel published additional information about the NSA’s techniques to infiltrate Cisco products.
“As a result of this new information coming to light, the Cisco Product Security Incident Response Team (PSIRT) has opened an investigation,” Stewart wrote in an update to his blog post.
According to Cisco’s security center site, the company “has requested, but has not yet received, the leaked documents referenced in the Der Spiegel article.”
