Data leaks and hacker attacks mean that internet security is becoming increasingly important for users. Standard passwords based on names and dates of birth can be cracked in seconds and give criminals access to all kinds of accounts. In combination with multi-factor authentication, TOTP can provide a solution: a password which is only valid for a short time. How does this work?

What is RAID 5?
  • Security

A Redundant Array of Independent Disks (RAID) can be used to improve data security or the performance of storage solutions. The specific advantages of a network depend on the selected RAID level. Find out how RAID 5 – a system of three or more hard drives – can improve security and throughput rate.

RAID 0
What is RAID 0?
  • Security

A Redundant Array of Independent Disks, or RAID for short, is a combination of several hard disks to form a single logical drive. Systems like these typically follows a redundant storage concept for higher security. The standard RAID 0 is an exception because it only seeks to optimize the data throughput by coupling several hard drives.
