# Best Practices for Connectors - Link: https://www.agilicus.com/best-practices-for-connectors/ - Published: 2023-05-26T13:40:10+00:00 - Author: Don Bowman The Agilicus Connector facilitates a private connection between a network and end- users. It installs on a device somewhere inside the protected network, creating an outbound connection, and is an essential part of Agilicus AnyX. But you may have questions about how to install and configure it. Do you run one per site? Or per host? What type of machine do you pick to put it on? We’ll share best practices so you can decide what works best for you.  For more information on the Agilicus Connector, refer to [this introduction to Connectors](https://www.agilicus.com/anyx-guide/agilicus-connector/). ## **_Best Practices for Connectors_** ![SSH Animated Data Flow](https://www.agilicus.com/www/d6c678de-ssh-data-flow.svg) SSH Animated Data Flow ### Micro-Segmentation The only thing technically required for the Connector is the ability to reach (connect, ping) the resource you’re trying to get to. These resources can be [remote desktops](https://www.techtarget.com/searchenterprisedesktop/definition/remote-desktop), web applications, [SSH](https://www.techtarget.com/searchsecurity/definition/Secure-Shell), or another similar service. The closer your users get to the resource they want to access, the more it will be secured against local risks. This is why we encourage you to have every machine that exposes resources to have its own Connector on it. This approach is more commonly known as micro-segmentation. There are ways through network deployment technologies that you can create that micro-segmentation without having a Connector. You can read more about that in this [whitepaper](https://www.agilicus.com/white-papers/zero-trust-microsegmentation/). Consider the below comparison.

In this model, a dual-homed industrial PC handles 2 segments, 1 entirely internal. ![Air Gapped Industrial Control](https://www.agilicus.com/www/6afe25d5-air-gapped- industrial-control.svg) ### Where to Install the Connector ![Agilicus Connector Best Practices: Illustration of a Connector Site with secure access to applications and data, emphasizing zero trust security principles and least privilege access. Connector sites enable controlled and audited access to internal resources from external networks, enhancing security and simplifying network management.](https://www.agilicus.com/www/bd3c88af-connector-sites.svg) We often get asked where the Connector should be installed, and we recommend putting it on a stable machine that will be up all the time. You don’t want it on a laptop in reception, for example.  The machine you install it on should of course have access to the resources and be close enough to the resources so that you’re not worried about something that’s closer that’s able to reach them without it. The Connector doesn’t require a lot of Memory or CPU and runs on almost any platform, so you have considerable flexibility. So in practice, most of our customers initially use one Connector per site or one per network. Let’s use an example of a company that has three subnets: a production network, an engineering network, and a marketing network. There could be three Connectors in that environment, but if the production environment has five different production lines, that might be one per line. In the diagram shown, installing a connector at (1) means the blast-radius is the entire building. Installing a connector at (2) means we can control access in and out of our data centre with high precision. Instaling at (3) means we can do privileged access to a single server (e.g. block all inbound traffic for remote desktop except through the Agilicus AnyX Zero Trust). A connector at (4) might suggest a departmental breakdown. Looking at a production facility, we might find one connector per manufacturing ‘ line’ (5). This would allow e.g. ensuring upgrades stay in the appropriate area and downtime. Moving the conector internal to each IPC can give perfect micro-segmentation. Not shown, but common, using network devices (e.g. VLAN’s with isolation) to achieve the same effect with less software deployed. ![Agilicus Connector Best Practices: Visual representation of connector deployments across multiple sites, emphasizing secure access and simplified network architecture.

This means there is more than one Connector that is always active. If, for whatever reason, the machine running the Connector died, your end users won’t experience any loss of service. High availability is not appropriate if you have a Share (in this model, you might handle the high-availability [externally](https://www.agilicus.com/anyx-guide/agilicus-connector-windows-cluster/), for example using Windows Clustering). ### Connector Nomenclature  It’s up to you how you choose to name your Connectors, but it should mean something to you. Most of our customers just use either the machine it is installed on, or the site/region/network segment for the name, but you may want to take a different approach.  ## Conclusion These best practices will help you use Connectors effectively in Agilicus AnyX and give you the information you need to set them up the way in the best way for your organisation’s needs.
