[irq]: techie interrupted

Our focus is on critical infrastructure services of computer and communication network. Typically, such services justify the use of server redundancy to improve service availability and dependability.

The first goal is incorruptible intrusion tolerance, which fends off or at least limits the damage of unknown and undetected attacks against critical servers. Our approach relies on mechanisms of intrusion tolerance that are shielded from external influence/attacks by hardware.

The second goal is to use spare, backup servers to improve both cluster security and service availability.

The building blocks of our solutions are constant server rotations and system self cleansing, regardless of whether an intrusion is detected or not.
