DARPA fortifies early warning system for power-grid cyber assault

The Defense Advanced Research Projects Agency (DARPA) continues to hone the system it hopes would quickly restore power to the U.S. electric grid in the event of a massive cyberattack. The research agency this week said it awarded defense system stalwart BAE Systems an $8.6 million contract to develop a system under its Rapid Attack Detection, Isolation and Characterization (RADICS) program that has as its central goal to develop technology that will detect and automatically respond to cyber-attacks on US critical infrastructure.+More on Network World: Cisco’s Jasper deal – one year, 18 million new IoT devices later, challenges remain+To read this article in full or to leave a comment, please click here

Hackers use dangerous Petya ransomware in targeted attacks

In a case of no honor among thieves, a group of attackers has found a way to hijack the Petya ransomware and use it in targeted attacks against companies without the program creators' knowledge.A computer Trojan dubbed PetrWrap, being used in attacks against enterprise networks, installs Petya on computers and then patches it on the fly to suit its needs, according to security researchers from antivirus vendor Kaspersky Lab.The Trojan uses programmatic methods to trick Petya to use a different encryption key than the one its original creators have embedded inside its code. This ensures that only the PetrWrap attackers can restore the affected computers to their previous state.To read this article in full or to leave a comment, please click here

How the IETF community is shaping technology to build a better society

The continued advancement in technological landscape enabling more people having Internet access in the global arena has meant that IETF (Internet Engineering Task Force) remains at the forefront of integrating technology with humanity. In fact, IETF has made significant use of social dimension to articulate its area of work and research. It is beautifully reflected in section 4.1 of the RFC 3935 wherein it states that “We want the Internet to be useful for communities that share our commitment to openness and fairness.  We embrace technical concepts such as decentralized control, edge-user empowerment and sharing of resources, because those concepts resonate with the core values of the IETF community”.

On the ‘net: PCEP

The original Path Control Element Protocol (PCEP) work dates from the early 2000’s, with the first IETF RFC (4655) being made informational in 2006—which means PCEP predates the time when SDNs were “cool.” PCEP was originally, because of the increasingly complex nature of computing Traffic Engineering (TE) paths through (primarily), Service Provider (SP) networks. Three specific developments drove the design, standardization, and deployment of PCEP —ECI Blog
