Defence in depth (also known as deep defence or elastic defence) is a military strategy that seeks to delay rather than prevent the advance of an attacker, buying time and causing additional casualties by yielding space. Rather than defeating an attacker with a single, strong defensive line, defence in depth relies on the tendency of an attack ...
The Swiss cheese model of accident causation is a model used in risk analysis and risk management. It likens human systems to multiple slices of Swiss cheese , which has randomly placed and sized holes in each slice, stacked side by side, in which the risk of a threat becoming a reality is mitigated by the differing layers and types of defenses ...
There are a number of strategies that can be employed as one measure of defense or in a combination of multiple strategies together. A risk assessment is an important tool that should be incorporated in the process of identifying and determining the threats and vulnerabilities that could potentially impact resources and assets to help manage risk.
In the first definitive book on defence mechanisms, The Ego and the Mechanisms of Defence (1936), [9] Anna Freud enumerated the ten defence mechanisms that appear in the works of her father, Sigmund Freud: repression, regression, reaction formation, isolation, undoing, projection, introjection, turning against one's own person, reversal into the opposite, and sublimation or displacement.

An example of a defense mechanism against this is the chain of trust (such as in iOS). This mechanism relies on signatures from applications required to start the operating system, and a certificate signed by the manufacturer (Apple). In the event that the signature checks are inconclusive, the device detects this and stops the boot-up. [47]
