Data Security at luckycloud

Server Infrastructure and Data Security at luckycloud

Our server infrastructure is entirely owned by luckycloud GmbH and is located in ISO-27001 BSI certified and highly available data centers in Germany. luckycloud creates, manages, and maintains the IT infrastructure completely independently. Other companies do not have access to the infrastructure or user data. All servers operate together as a cluster. Due to a special architecture, there is no Single Point of Failure (SPOF). The server infrastructure can be horizontally scaled as needed.

Additionally, all data is transferred in real-time to a geo-redundant backup infrastructure for disaster recovery. This high-availability setup ensures that the systems remain available despite potential system failures and attacks. Server activities are continuously monitored and optimized, just like the firewall, which is regularly adjusted to potential threats.

An IP and port-based firewall automatically blocks unauthorized and unknown access. We also employ DDOS protection and the latest technologies to intercept potential attacks early.

Our data centers have a generously dimensioned power supply and are supplied by two independent 10 kV Vattenfall lines. Despite the very good power supply, a battery-supported UPS with connected diesel generators is available for emergencies. Maintenance contracts with diesel suppliers are as standard as a management plan for the fire department.

All rooms are fully air-conditioned. The air conditioning units control both the room temperature and humidity. There is proactive optical, thermal, and chemical fire detection and gas extinguishing.

Server Storage

All data is stored in a highly available SDS cluster. Software-Defined Storage is a highly available, distributed, and robust file system that is completely based on open-source. SDS is a distributed file system across multiple nodes, hence it is also referred to as an SDS cluster. In an SDS cluster, there are always multiple roles taken on by individual nodes. SDS was developed for the use of highly scalable object, block, and file-based storage in a unified system.

Failover Protection – Separate Data Centers

User requests are directed to the luckycloud data backend via highly available load balancers. The backend servers work together as a cluster and receive connections from the load balancer depending on the load. Through a floating IP setup, there is no Single Point of Failure (SPOF). The backend servers operate "stateless" and can be horizontally scaled as needed.

Additionally, the data is transferred in real-time to a geo-redundant backup infrastructure (NFS cluster) and can be accessed directly in a disaster scenario. A simplified representation can be found below under the point "High-Availability luckycloud Data Backend Cluster."

Authentication and Security Systems

There are various ways to authenticate access to the infrastructure.

  • Username and Password: A minimum of 8 characters, uppercase and lowercase letters, and a special character are required.
  • Single Sign-on (SSO): Open Authorization (OAuth) is an open protocol that allows standardized, secure API authorization for all desktop, web, and mobile applications.
  • Two-Factor Authentication (2FA): Two or multi-factor authentication is a recognized and recommended method for securing remote access to cloud services and web applications. Two-factor authentication is only referred to when two different factors from the areas of possession, knowledge, and being are used for login.
  • Remote Wipe: Remote data deletion on lost laptops or smartphones via Remote Wipe.

How can I protect myself from device theft?

In the cloud, your data is securely encrypted. But what about your local data? Are these also sufficiently protected?

Secure Passwords

You've probably heard this before, but a secure password makes a big difference – this applies not only to your user password at luckycloud. You should also adequately protect your device accounts. Here are some tips:

  • The longer a password, the better.
  • Use numbers, symbols, uppercase and lowercase letters.
  • Create mnemonic devices to better remember your password.
  • Or: Use a password manager, such as KeePass.
Sufficiently Encrypt Devices or Hardware

To be protected in the event of theft, burglary, or loss, you should have sensitive data locally on your laptop/PC and also encrypt your hard drive. There are tools on the market like Bitlocker or VeraCrypt that can encrypt your local hard drive.

If you use such a tool and work with the sync client, you must disable the automatic start of the sync client when restarting the PC/laptop. Upon restart, the data must first be decrypted locally. After that, you can start the sync client and use it as usual.

Touch ID/Face Recognition/Movement Lock for Mobile Devices

Use Touch ID, face recognition, or movement lock on your mobile device for additional security.

Remote Wipe Function

Remote Wipe: Remote data deletion on lost laptops or smartphones via Remote Wipe.
