Please describe the setup you are using for your validator? Include any relevant security information, processor speed, backups and sentry nodes etc…

1: Validation Servers
It is recommended for validation servers to not hold the validation keys of the validator, as compromise of the servers could lead to theft of key material.
Major decisions we faced regarding validation servers were: How many validation servers to use, where to host them and what software to run on them.
First of all, let’s visit the question of where to host these machines. There are 2 main options: Rely on a cloud provider such as AWS to provision these machines for us.
Or purchase servers, and purpose them as validation servers, in Tier III & IV data centers with 100% network uptime guarantee.

All selected data centers operate monitored closed circuit television, and are manned by both security and technical personnel 24/7/365. Access to racks is limited to the providers’ personnel via biometrics and access card controlled man-traps. The data centers are carrier neutral and connected via diverse routes to multiple tier 1 connectivity providers, and are monitored 24/7/365 by either a remote or on-site Network Operations Center (NOC). Similarly, both are connected to multiple power substations, and are backed by at least N+1 generators. As a result, both vendors offer 100% network connectivity and power SLAs. In addition, in the event of hardware failure, vendors are subject to a one hour hardware replacement SLA.

2: Sentry Layer
Sentries are full nodes (for a specific network) placed between the public Internet and the validation servers. Sentry nodes ensure that validation servers are not directly exposed to the public Internet, connect to other full nodes on the network, gossip transactions plus blocks, keep validation servers up in sync with the network, and act as the first line of defense against DDoS attacks. They can also be repurposed for the role of transaction filtering to guard against transaction spam attacks. We’ve deployed sentry nodes on AWS or DO, or Hetzner, as they are less security critical than the validation servers.

3: Logging & Monitoring
Observability of an Infrastructure estate is one of the most basic, but most powerful tools at the disposal of an engineer. It allows one to view, understand, proactively respond, and be automatically alerted to changes in the behavior or performance of servers.
It can be broken down into three main streams:

4: DDoS Protection
In order to mitigate the impact on hosts of denial of service attacks (Denial of Service Attacks, Wikipedia) we route inbound packets from the public Internet via cloud-provider DDoS protection.
In addition to our public sentries, we run ‘private’ sentries behind NAT (Network Address Translation, Wikipedia) gateways that only permit outbound connections so that in the event of a targeted attack against our public nodes, we will be able to continue receipt and transmission of P2P packets to and from the wider network.
These private sentries are also ‘privately peered’ with carefully selected partners via cloud-provider network peering, to ensure both parties benefit from each others’ connectivity even in the harshest of adversarial climates.

5: No Public-facing SSH Ports
Operation of our nodes is ultimately conducted via SSH - although we minimise this as much as humanly possible through automation - but as poorly SSH protected SSH endpoints are a primary target for any intruder, we do not expose SSH on any port (exposing on a non-default port is considered security-through-obscurity, and a poor countermeasure), preferring to utilise an encrypted VPN for all control traffic in and out of our infrastructure.
are created, and for all users regardless of their position in the company.

6: Conclusion
Our operations consist of dedicated servers located in the specialized and highly qualified well-known data centers around the world, using only the highly secure networking and role-model infrastructure setups with the full regular back-up using the N + M scheme, controlled by the external independent watchdog services.
