1. The Architecture of IRCan’s HRE

2. What is IRCan? A Government initiative started by the Treasury Board Secretariat of Canada and Public Works and Government Services Canada. Has the mandate to provide mechanisms to create and archive reusable digital assets (Intellectual Resources) that interest The Crown.

3. Problem Provide a flexible, upgradable, dependable, infrastructure that Government departments can use to host applications and projects, involving FLOSS applications and tools. Provide the capability to implement each project’s security policy, within the greater responsibilities of The Crown. Provide a solution that doesn’t “get in the way” of receiving a certificaton from SSC authority.

11. The Parts

12. IRCan Firewall Bridge-based Rules constrain MAC addresses, ports and protocols. MACs are verified against client DB. Web-controlled by client Choice of pre-defined security policies. Each comes with standard docs that client can submit with their certification request.

13. VM disk infrastructure DRBD offers live replication between pairs of nodes. Block Devices are paired for high availability. The VM images must be pre-sized. Possible Elastic Storage provided in the future.

15. VM provisioning Customer may choose to use one of our hardened distro, which comes with standard docs that they can submit with their certification request.

16. Customer Setup Still being worked on. Customer given a token that they use to register themselves on our self-serve website. Mini-cloud automatically created with a VPN endpoint dedicated to the client. VPN certificate wrapped with whatever crypto the customer gave us: SSH, PGP, SSL

17. Customers Cloud Setup Customers connect to their VPN endpoint and connect to our internal self-serve website. Customers can create new VMs and Private Networks, and can push firewall policies to our IRCan firewall.

18. Customer Services Customers may elect to be monitored and backed-up. They push data to our customer service servers. Customers are not forced to run proprietary agents. Outbound email forwarding provided, not inbound filtering. DNS can be primary or secondary.
