What are fail-safe defaults?
Fail-safe defaults: Base access decisions on permission rather than exclusion. This principle, suggested by E. Glaser in 1965, 1 means that the default situation is lack of access, and the protection scheme identifies conditions under which access is permitted.
What is fail safe defaults in BIOS?

What is the difference between fail safe and fail secure?
While fail-safe products are unlocked when power is removed (i.e. power is applied to lock the door), fail-secure products are locked when power is removed (i.e. power is applied to unlock the door). Fail safe/fail secure refers to the status of the secure side (key side, outside) of the door. Similarly, you may ask, what is fail safe condition?

What is fail-safe and fail set?
What is meant by 'fail safe' and 'fail set' in a pneumatic control systems ?

What is non fail-safe?
A non fail-safe actuator will keep the valve tightly secured if the valve loses connection to the power source. These actuators have excellent thrust strength that ensures the valve will retain its last position. This type of mechanism is typically used in high thrust applications.May 24, 2021
What is fail-safe design and why does it matter?
Fail-safe designs are designs that incorporate various techniques to mitigate losses due to system or component failures. The design assumption is that failure will eventually occur but when it does the device, system or process will fail in a safe manner.

Abstract
When a system fails, it should do so securely. This typically involves several things: secure defaults (default is to deny access); on failure undo changes and restore to a secure state; always check return values for failure; and in conditional code/filters make sure that there is a default case that does the right thing.
Detailed Description Excerpts
According to [Saltzer 75] in "Basic Principles of Information Protection" on page 8:
Elevators
Elevators are typically designed with special brakes that are held back by the tension of the elevator's cable. If the cable snaps the loss of tension causes the brakes to be applied.
Trains
Railway trains commonly have air brakes that get applied automatically with the failure of the main brake system.
Earthquakes
Elevators and trains in earthquake prone regions such as Japan are often configured to detect earthquakes and automatically stop. Elevators may be designed to stop at the nearest floor and open their doors. In some cases, such systems are hooked up to earthquake early warning systems and can potentially stop seconds before an earthquake arrives.
Flight Control
Flight control computers are typically designed with redundancy so that if one goes down another kicks in. They may also be designed to detect a flight control computer that suffers from "insanity" meaning that it appears to be dysfunctional due to damage or other factors.
Electronic Locks
Electronic locks that are designed to be unlocked by default in the event of power failure. Some vehicles don't have this feature and it's possible to get locked in a car that loses power.
Traffic Lights
Traffic lights may be designed to blink red in all directions if their controller goes down.
Deadstick Landing
Aircraft are designed with some ability to glide and can be landed without any engine power. This isn't completely safe but is certainly possible with a competent pilot if there is a suitable landing spot within range.
What is a fail safe lock?
Most people would think that fail safe locks are there to allow fast exit in case of emergency. This is called "egress" and egress has always to be granted nevermind the lock. That means with a fail secure or fail safe lock you can ALWAYS exit the door or building - emergency or not. The terminology of fail safe or fail secure is only around ENTRY control which means it determines what happens in case of an emergency with entry. If all doors would be un-accessible during a fire - fire fighters or medical staff could be hindered to help properly.
Why is a fail safe lock called a safe?
To keep it locked during normal business operations, power is applied. Should the power be interrupted or fail, the door automatically unlocks or releases to let people out of the space. That's why it's called "safe" - it's safe for people - not the space! Mostly fail safe locks are used for main entry points like office doors or lobby access doors.
Why do offices have fail safe locks?
One big reason why many offices do this is because glass doors which look a lot better are much more popular.
Why do locks fail secure?
Often fail secure locks are used for IT rooms or other sensitive areas. However because the door keeps being locked in emergencies, typically it will be usable with a mechanical override, such as a regular key. However this is also a way of getting in the door without leaving any electronic traces.
What does "fail secure" mean?
So in the end fail secure means that if the power is interrupted or fails, the door stays locked. That's why it's called "secure": It's default state is locked or secured. So a fail secure lock locks the door when power is removed. Often fail secure locks are used for IT rooms or other sensitive areas.
Can you exit a door with a fail safe lock?
That means with a fail secure or fail safe lock you can ALWAYS exit the door or building - emergency or not . The terminology of fail safe or fail secure is only around ENTRY control which means it determines what happens in case of an emergency with entry.
What is fail safe default?
The idea behind fail-safe defaults is that, when a system fails, it should still be able to maintain a secure state. This is typically done by denying access to any object outside the scope during downtime.
What is security configuration?
Security configuration is the set of measures that are employed during the construction and installation of computers in the network. It helps in reducing unwanted security vulnerabilities in the system. It also includes the removal of unwanted functionalities to eliminate the possibility of a security breach.
