New attack scheme on Office 365 corporate users

KnockKnock is discovered by Skyhigh Networks experts, who noted that the key distinction of this new attack is the nature of the accounts that are being targeted. The attack targets on system accounts that are not assigned to any one individual user. System accounts have more privileges and, in addition, they have a more loyal password policy. Having access to the account, it is easier for hackers to continue attacking the corporate network.

Skype for Business Cloud Connector Edition (CCE) is a hybrid solution that allows integrating the corporate PBX with the Office 365. CCE offers a set of components offering organizations to connect to the corporate PBX or PSTN, organize the SIP trunk from your Office 365 (Skype for Business Online).

This service gives you a turnkey Cloud Connector Edition (CCE) infrastructure setup.

We will deploy the necessary topology in a virtual environment. Users from your organization will be able to place / receive calls from landline and mobile phones through any existing voice infrastructure, for example through the corporate PBX or SIP trunk of a VOIP provider. If your corporate PBX does not support SIP protocol over TCP, we’ll set up an additional gateway for connection.

Work performed during deployment of Cloud Connector Edition (CCE) for Skype for Business Online:

  1. Set up of the required package of Virtual Machines:
  • Domain Controller
  • Central Management Server (CMS)
  • Mediation Server
  • Edge Server
  1. Configuration of the above-mentioned VMs.
  2. Setup of VOIP gateway for connection with the corporate PBX or PSTN.
  3. Testing of the functionality.

For the companies that require High Availability, we offer to deploy 2 CCE packages (2 x 4 Virtual Machines, i.e. 8 virtual machines in total).

Infrastructure Requirements:

Minimum CCE solution (up to 50 simultaneous calls) – 64-bit 4-core processor/ 32 GB RAM/ 200Gb HDD) / 2 NIC.

Skype for Business – Cloud Connector Edition (CCE)

Cloud Connector Edition1

A couple of days ago Microsoft released the Cloud Connector Edition (CCE) for Skype for Business Online, a hybrid solution that enables integrating your corporate PBX with the Office 365. CCE includes a set of components allowing organizations to connect to the PSTN, or organize the SIP trunk from Office 365 (Skype for Business Online). This solution is useful for countries in which there is no possibility of using the telephone connection directly in Office 365 Enterprise E5, since the feature is currently available only in the United States.

What is Skype for Business CCE?

Skype for Business Cloud Connector Edition (CCE) is a hybrid solution that consists of multiple Virtual Machines (VMs) implementing local connectivity with the Cloud PBX.

Deploying the minimal Skype Business Server topology in a virtualized environment (whether it’s cloud or on-premise solution), users in the organization are able to send and receive calls from landline and mobile phones via any existing voice infrastructure, for example through the corporate PBX or SIP trunk of you VOIP provider.

The structure of CCE includes a package of four Virtual Machines that should be deployed and configured using the setup wizard. Here is the list of virtual machines:

  1. Domain Controller
  2. Central Management Server (CMS)
  3. Mediation Server
  4. Edge Server

In this case, there is no dependency on the existing Active Directory infrastructure during the deployment phase, as it creates its own forest independently. It’s recommended to place the CCE Virtual Machines in the DMZ. Companies that need High Availability can deploy 2 CCE packages (2 x 4 VMs, that is 8 VMs in total).

Licensing

There is no need to purchase licenses for virtual servers included in the Cloud Connector Edition (CCE). However, Office 365 users using a hybrid configuration require licenses, and need to purchase E5 enterprise plan.
