6 shows the breakdown of the set Tolerable Hazard Rate (THR) either for a subsystem in terms of Failure Rate (FR), or for the hardware making up that subsystem in accordance with the architecture (in which case, independence hypotheses may be made), and the division of the SIL either for each subsystem in terms of SIL (giving us the SSIL) or for the hardware (or software) components: – the hardware’s SIL is identical to the SIL of the subsystem; – the software’s SSIL is identical to the SIL of the subsystem.

Today, though, contractual obligations as regards performances have led industrialists in the railway sector, for example, to very carefully define the parameters 22 CENELEC 50128 and IEC 62279 Standards affecting a system’s reliability, availability and maintainability (RAM). The choice of norms and standards is the responsibility of the designer and/or manufacturer. 4. Software safety CENELEC EN 50128 [CEN 01a, CEN 11a] specifies the procedures and technical prerequisites applicable to the development of programmable electronic systems used in railway control and protection applications.

Risk and Safety Integrity Level 39 The basic principle is to prevent the object of the security (the data) from entering a communication channel: to do so would be compromising for a certain party, and the system needs to be secured in light of that fact. Generally, we speak of a “gray channel” for the secured communication channel. Applications used to communicate over the gray channel must have a mechanism for encoding and decoding the data exchanged. This mechanism must be able to serve the security objectives.
