New Juniper Security CTO promises open framework for software defined network security

/in

The new Juniper Networks liaison between the company’s engineering team and its customers says it will take time, but Juniper’s software defined security networking (SDSN) will eventually support third-party devices to help build security into the network fabric itself.

It’s part of a shift from network security to a secure network that is flexible thanks to software defined networking, says Kevin Walker, Juniper’s Security CTO.

The SDSN framework is designed to leverage the capabilities of the entire network to detect and assess threats, and enforce security policies across switches, routers and firewalls. Recently Juniper CEO Rami Rahim referred to this framework as “the rolling thunder of security enhancements.”

According to the ISC warning, the upgraded yellow warning was made because Juniper’s NetScreen firewalls are popular and that the “’backdoor’ password is now known, and exploitation is trivial at this point,” and for most businesses, this “being a short week for many of us, addressing this issue today is critical.”

After Juniper security mess, Cisco searches own gear for backdoors

/in

While it says it has no reason to think there are backdoors in any of its products, Cisco has started an additional code review looking for “malicious modifications” after Juniper’s announcement that its ScreenOS operating system has been vulnerable for years.

“Our additional review includes penetration testing and code reviews by engineers with deep networking and cryptography experience,” according to the Cisco Security blog written by Anthony Grieco, senior director of the company’s Security and Trust Organization. The company says it will release its findings in accordance with its security vulnerability policy.
