In a world of accelerating safety threats, IBM Cloud provides quite a lot of options to help you in safety and compliance. Now we have included a number of IBM Cloud providers into our Citrix-DaaS resolution, enabling you to simply rise up a safe deployment out of the field. In managing your risk vectors, it’s a good suggestion to have a single level of entry into your VPC. Moreover, having zero publicity to the web and encryption helps forestall attackers from compromising your deployments. Centralized logging helps you monitor down points in your atmosphere shortly and successfully.
When you require stricter safety and compliance requirements inside your Citrix DaaS deployment on IBM Cloud, you should use these IBM Cloud assets and options to customise your workload safety:
Bastion host: Offers a safe approach to entry distant cases inside a Digital Personal Cloud (VPC).
Shopper-to-site VPN: Offers client-to-site connectivity, which permits distant units to securely connect with the VPC community by utilizing an OpenVPN software program shopper.
Buyer-managed encryption: Protects information whereas in transit from block storage to the host/hypervisor and whereas at relaxation in volumes.
Entry management listing (ACLs): Used with safety teams to limit entry to NIC port ranges.
Log evaluation: Makes use of IBM Log Evaluation to supply logs multi functional place.
Provision a bastion host
A bastion host is an occasion that’s provisioned with a public IP handle and will be accessed through SSH. After setup, the bastion host acts as a leap server, permitting safe connection to cases provisioned with out a public IP handle.
Earlier than you start, it’s worthwhile to create or configure these assets in your IBM cloud account:
IAM permissions
VPC
VPC Subnet
SSH Key
To scale back the publicity of servers inside the VPC, create and use a bastion host. Administrative duties on the person servers are carried out by utilizing SSH, proxied via the bastion. Entry to the servers and common web entry from the servers (e.g., software program set up) are allowed solely with a particular upkeep safety group that’s connected to these servers.
For extra info, see Securely entry distant cases with a bastion host.
If you wish to arrange a bastion host that makes use of teleport, see Organising a bastion host that makes use of teleport.
Create a client-to-site VPN for safety
The VPN server is deployed in a specific multi-zone area (MZR) and VPC. All digital server cases are accessible from the VPN shopper within the single VPC:
You may create your VPN server in the identical area and VPC the place your DaaS deployment resides.
Relying on the shopper authentication you chose throughout VPN server provisioning, customers can connect with the VPN server by utilizing a shopper certificates, consumer ID with passcode or each.
Now you possibly can connect with your DaaS VSIs out of your native machine(s) by utilizing non-public IP solely.
Use customer-managed encryption to encrypt your information end-to-end
By default, VPC volumes are encrypted at relaxation with IBM provider-managed encryption. There is no such thing as a further value for this service. For end-to-end encryption in IBM Cloud, it’s also possible to use customer-managed encryption the place you possibly can handle your personal encryption. Your information is protected whereas in transit from block storage to the host/hypervisor and whereas at relaxation in volumes.
Buyer-managed encryption is offered in VPC by utilizing IBM Key Shield for IBM Cloud or IBM Hyper Shield Crypto Providers (HPCS). The Key Shield or HPCS occasion have to be created and configured earlier than the order movement inside Citrix-DaaS. The Identification quantity encryption choice on the Citrix-DaaS order UI is then used to encrypt every identification disk related along with your machine catalog inside Citrix Machine Creation Providers (MCS).
Use entry management lists to limit port ranges
By default, Citrix-DaaS deployments create a number of safety teams (SGs) designed to isolate entry between NICs. For extra info on SGs, see About safety teams. There is no such thing as a inbound entry from the web by default except you select to assign floating IPs (FIP). We suggest establishing VPN as described on this article over utilizing FIPs. Safety teams include a limitation of 5 SGs per community interface card (NIC), which leaves some pointless port ranges open that may be additional restricted by utilizing entry management lists (ACLs).
For extra details about utilizing ACLs, see About community ACLs. For details about Citrix-DaaS port ranges, see Technical Paper: Citrix Cloud Communication.
Use IBM Log Evaluation to watch logs for compliance and safety
For many Citrix-DaaS deployments, centralized logging is essential. With out centralized logging, you might be pressured to search out logs for every particular person part throughout a number of assets. For instance, some logs are on the Cloud Connector VSIs (Connector Logs and Plug-in) and Area Controller logs are on the Energetic Listing Server. In case you are utilizing Quantity Employee, logs are cut up between IBM Cloud Capabilities and the employee VSIs that full the roles. A few of these logs are ephemeral and are usually not accessible if not being recorded by centralized logging.
Centralized logging is offered by utilizing an IBM Log Evaluation occasion and might present logs multi functional place. IBM Log Evaluation can both be provisioned with the Citrix-DaaS deployment or an ingestion key for an present occasion offered via a Terraform variable. As a result of centralized logging is extraordinarily essential for this product, it’s enabled by default; optionally (with a Terraform variable), it may be disabled.
Conclusion
A number of IBM Cloud providers are included into the Citrix DaaS resolution, so you possibly can simply rise up a safe deployment out of the field. You may configure stricter safety inside your deployment on IBM Cloud. Primarily based on the enterprise wants, you possibly can customise the safety precautions that you just require to combine along with your deployment.
