Defensive design is the practice of planning for contingencies in the design stage of a project or undertaking. Essentially, it is the practice of anticipating all possible ways that an end-user could misuse a device, and designing the device so as to make such misuse impossible, or to minimize the negative consequences.
Defensive programming is a form of defensive design intended to develop programs that are capable of detecting potential security abnormalities and make predetermined responses. [1] It ensures the continuing function of a piece of software under unforeseen circumstances.
Defensive computing is a form of practice for computer users to help reduce the risk of computing problems, by avoiding dangerous computing practices. The primary goal of this method of computing is to be able to anticipate and prepare for potentially problematic situations prior to their occurrence, despite any adverse conditions of a computer system or any mistakes made by other users.
Examples of this strategy include using gateways, routers, firewalls, and password checks, deleting suspicious emails/messages, and limiting physical access. Boundary protection is typically the main strategy for computing systems; if this type of defense is successful, no other strategies are required.
The third category includes work products that describe system design guidelines and requirements for the secure integration of control systems. The core of this is the zone, conduit, and design model. The fourth category includes work products that describe the specific product development and technical requirements of control system products.
In modern English usage, the informal term idiot-proof or foolproof describes designs that cannot be misused either inherently, or by use of defensive design principles. The implication is that the design is usable even by someone of low intelligence who would not use it properly. The term "foolproof" originates in 1902. [1]
Defense in depth is a concept used in information security in which multiple layers of security controls (defense) are placed throughout an information technology (IT) system. Its intent is to provide redundancy in the event a security control fails or a vulnerability is exploited that can cover aspects of personnel , procedural , technical and ...
Design by contract (DbC), also known as contract programming, programming by contract and design-by-contract programming, is an approach for designing software. It prescribes that software designers should define formal , precise and verifiable interface specifications for software components , which extend the ordinary definition of abstract ...
