As the CIA’s Linux-targeting OutlawCountry and Gyrfalcon code is revealed, two reports claim Linux malware attacks are rising quickly. Over the past few years, anecdotal evidence has suggested that security threats to Linux devices are on the rise. Last fall’s Mirai botnet attacks, which turned thousands of Linux devices into a zombie army used to […]

Depending upon the event you use to start the clock, cloud computing is only a little more than 10 years old. Some terms and concepts around cloud computing that we take for granted today are newer still. The National Institute of Standards and Technology (NIST) document that defined now-familiar cloud terminology—such as Infrastructure-as-a-Service (IaaS)—was only published in 2011, although it widely circulated in draft form for a while before that.

Over the past few years, anecdotal evidence has suggested that security threats to Linux devices are on the rise. Last fall’s Mirai botnet attacks, which turned thousands of Linux devices into a zombie army used to attack infrastructure via Distributed Denial of Service (DDoS), were particularly effective in waking up the Linux community.

This article is based on OpenFlow and OVSDB connection between SDN controller and OpenFlow-based switches and provides details on connection lifecycle. We will use open source SDN controller i.e. Opendaylight (ODL) Carbon release and OpenFlow virtual switch i.e. OpenVswitch (OVS) version 2.6.0 to describe OVSDB and Openflow connection.

Mozilla unveiled “Project Things,” which builds upon standard web technologies and the Web of Things project, and released code that runs on a Raspberry Pi. In March of last year, a few months after Mozilla announced it was shutting down its Firefox OS project for Linux-based mobile phones, it unveiled four Firefox OS based “Connected […]
