Security or cybersecurity are methods to protect the assets of the system from external, harmful and malicious actors or entities.Īssets include personal information, Keys used in the system for encryption and decryption, Memory regions used for storing data which on compromise of integrity leads to disastrous outcome in the system, APIs and resources exposed by the system. To note there are processes with iso26262 to analyse the various Random Hardware faults within the system. Lets go back to the example of the DRAM flip bits - Such bit flips are eliminated using ECC safety mechanism which detect and correct the bits in hardware. Note I use the term faults and not Random faults (Food for thought ?)
#Financial safe synonym software
Yes such faults can be detected and appropriate actions can be taken through a safety mechanism.Ī safety mechanism is a method in software or hardware or in combination to detect and mitigate the faults. Since the random faults are unpredictable does it mean that there is no way to mitigate such faults. Examples include bit flips in DRAM because of the hardware getting older and hence the wrong data being consumed by the software which could cause harm. What are random faults ? Random faults are faults that occur unpredictably in a system. Examples of such processes are ASPICE, ISO26262, IEC608 etc.īut does just following a process make sure that the safety of the system is assured ? This is truly an interesting question that every organisation/business needs to ask itself and we will discuss on this in the future articles. Hence to reduce and eliminate such faults the system(software/hardware) are developed systematically as in following a set of processes to make sure the faults produced are reduced overall. Examples of systematic faults are lack of integration tests, no proper quality analysis, implementation of functionaries not defined by the requirements, architecture or design.
What is a systematic fault ? A fault that in general that is caused by a human mistake in its most simplest terms.
Software faults are always systematic faults and Hardware faults can be both Random or systematic faults. Is there is relationship with Group 1 and Group 2 ? Yes absolutely To understand this we should what kind of bugs are present in a system specifically in an embedded system. You might be like alright but what does it mean to me developing software and how do I understand this construct. What does the term "unavoidable risk" mean ? It means risks that have been identified and has a degree of causing harm and damage. To understand safety and security let understand the terms. Does this mean Security and Safety synonyms ? This article would like to explore this and further deep dive in to understanding what really makes a safe and secure system. These words have been used interchangeable in tech space for a long time. Security and Safety have become buzz words recently with technology being shifted from Mobile to IoT to Automotive.
