In Taekwondo to win you watch your opponent’s center of gravity (CoG), for the eyes lie. For example, if the CoG moves toward their back foot you can expect a front kick, or if it begins a slight twist without moving forward or backward then a punch from the arm in the direction of the twist is coming. These are mandatory anticipatory movements which are precursors to a pending threat. If my opponent throws a punch or launches a kick without these movements it will be ineffectual. A punch without a twist is a tap. Of course the above is no secret. Skilled attackers lead with a feint to disguise their real intent, but that’s for another time. Cybersecurity is no different, you need to detect a threat, see it, classify it, then act on it. Detecting and seeing the threat is commonly referred to as Visibility. Classifying then acting on the threat is called Orchestration.
Imagine if you could watch the CoG of every server in your data center? In cyber terms that CoG might be every data flow in/out of the server. Placing boundaries and alerts on those flows is the primary role of orchestration. Placing these boundaries is now called micro-segmentation. Recently we suggested that the New Network Edge is the server itself. Imagine if you could watch every data flow from every server, set up zero trust policies to govern in advance which flows are permitted, then the system generates alerts to security operations when other flows are attempted. With solid governance comes the capability to quarantine applications or systems that have gone rogue. All the while all of this is done within the server’s own NICs, without any host agents or utilizing any local x86 CPU cycles, that’s Solarflare ServerLock.
Below is a screenshot of ServerLock displaying seven groups of hosts, in the dark grey bubbles, with all the flows between those hosts in red. The Database servers group is highlighted, and all the network flows for this group are shown. Note this is a demonstration network. Click on the image below to see a larger version of it.
