How Jefferson County’s IT Department Improved Their Security Posture with VMware NSX
Jefferson County, Colorado (“Jeffco”) is a local jurisdiction located against the beautiful Rocky Mountains and adjacent to the state capital in Denver. Jeffco’s IT 
organization is charged with meeting the needs not only of the various internal departments of the county, but also of serving its half million residents.
As with most IT departments, Jeffco’s IT team has some key priorities to address, including modernizing application infrastructures and bringing more efficiency to business processes — all while fundamentally enhancing security. It was these needs that led Jeffco to VMware NSX. “We’re doing as much as we can to simplify our infrastructure, yet provide more security, higher up time, and better performance,” says Matt Alexander, Senior Systems Administrator.
Like many other organizations, Jeffco first considered VMware NSX for micro-segmentation. Their network had followed the traditional model of data center security: perimeter firewalls, DMZ, internal security zone. But this legacy security model wasn’t enough. Jeffco recognized the need to treat all network traffic — regardless of whether it originated inside or outside the data center — as potentially insecure. “From a micro-segmentation and east-west firewalling perspective, we may have had the ability [in the past] but it was exceptionally expensive with physical Continue reading
Microsoft gets support for its fight against government gag orders
Microsoft has secured some big allies in a fight against the federal government, including three of its chief rivals, plus a hometown airline.
Microsoft is fighting the government over its right to tell customers when federal agents request their data and emails. The company filed a lawsuit in April against the federal government, charging such gag orders violate the Constitution and threaten the future of cloud computing.

snaproute Go BGP Code Dive (10): Moving to Established
In the last post on this topic, we traced how snaproute’s BGP code moved to the open state. At the end of that post, the speaker encodes an open message using packet, _ := bgpOpenMsg.Encode(), and then sends it. What we should be expecting next is for an open message from the new peer to be received and processed. Receiving this open message will be an event, so what we’re going to need to look for is someplace in the code that processes the receipt of an open message. All the way back in the fifth post of this series, we actually unraveled this chain, and found this is the call chain we’re looking for—
- func (st *OpenSentState) processEvent()
- st.fsm.StopConnectRetryTimer()
- bgpMsg := data.(*packet.BGPMessage)
- if st.fsm.ProcessOpenMessage(bgpMsg) {
- st.fsm.sendKeepAliveMessage()
- st.fsm.StartHoldTimer()
- st.fsm.ChangeState(NewOpenConfirmState(st.fsm)) }
I don’t want to retrace all those steps here, but the call to func (st *OpenSentState) processEvent() (around line 444 in fsm.go) looks correct. The call in question must be a call to a function that processes an event while the peer is in the open state. This call seems to satisfy both Continue reading
