Certificate Authority ?

Problem : How can we trust a website claiming to be who they are ?

Me browser https://www.youtube.com

-------------------------->

give me youtube

<-------------------------

youtube certificate contain

youtube public key signed by Google CA

-------------------------->

Google CA is trusted , therefore the youtube

public key is trusted.

here are the new secret key encrypted with youtube public key

Due to it was encrypted with youtube public key,

therefore youtube will be able to decrypt it with

youtube private key and able to read the new secret key.

<------------------------------->

All future communication between my browser and youtube

will be encrypted with the new secret key.

Therefore the commuinication is secure and each party is trust as who they claim.

Linux Bridge , vnet and VM --> how it all bind togather

2015-09-10T17:18:00.000-07:00

SDN => software define network use software bridge to make thing happen ... all for the cloud

• We created a Linux bridge and added a physical NIC interface of the host.
• Then while creating a VM, we specified the Linux bridge to be used for virtual networking.
• The Virtual Machine Manager (libvirt GUI) did some behind-the-scene work
to associate the Virtual NIC to the Linux bridge and in turn to the Physical NIC.
• We then observed how the VM’s virtual NIC is associated to the virtual tap interface on the host.
And how the tap interface is added to the Linux bridge.
• This shows that the traffic will flow from the VM’s virtual NIC to the vnet0 tap interface,
then onto the Linux bridge (virtual switch) which will send it out on the other virtual switch interface (eth0) on the host.

Example :

[root@host]# brctl show
bridge name bridge id STP enabled interfaces
bridge0 8000.5cb90178da58 no eth1
vnet1
vnet2
vnet4
bridge1 8000.fe54006d07b8 no vnet3
bridge2 8000.5cb90178da50 no eth0
vnet0
bridge3 8000.fe5400fdaa91 no vnet5
virbr0 8000.52540055b76e yes virbr0-nic

Above example detail what bridge is define and which interface is connected to the bridge

To identify which vm the vnet is associated user need to check the MAC address on the vm interface and compare
it to the ifconfig -a on the host vnet#
