Minimization

Having the least functionality necessary in a program or device

Least Privilege

In information security, computer science, and other fields, the principle of least privilege (PoLP), also known as the principle of minimal privilege or the principle of least authority, requires that in a particular abstraction layer of a computing environment, every module (such as a process, a user, or a program

Class

In object-oriented programming , a class is a template definition of the method s and variable s in a particular kind of object . Thus, an object is a specific instance of a class; it contains real values instead of variables. The class is one of the defining ideas of object-oriented programming.

Inheritance

In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object (prototype-based inheritance) or class (class-based inheritance), retaining similar implementation. ... An inherited class is called a subclass of its parent class or super class.

Confidentiality

It is an expectation for the entity entrusted with data (or code) to keep it a secret. For example, if a healthcare provider is entrusted with patient data, the user expects the health care provider to keep it secret.

Layer

Layer (object-oriented design) In object-oriented design, a layer is a group of classes that have the same set of link-time module dependencies to other modules. In other words, a layer is a group of reusable components that are reusable in similar circumstances

Defense Layering

Layered security refers to security systems that use multiple components to protect operations on multiple levels, or layers. ... Layered security may also be known as layered defense.

Modularity

Modularity refers to the concept of making multiple modules first and then linking and combining them to form a complete system. Modularity enables re-usability and minimizes duplication. ... Modular programming is an extensively used concept based on modularity. Modularity is also a feature of object oriented programming.

Members

Objects can have their own data, including variables and constants, and their own methods. The variables, constants, and methods associated with an object are collectively refered to as its members or features

Data Hiding

Only allow necessary aspects of a data structure or a record to be observed or accessed. Log all access attempts.

Polymorphism

Polymorphism is one of the core concepts in OOP languages. It describes the concept that different classes can be used with the same interface. Each of these classes can provide its own implementation of the interface. Java supports two kinds of polymorphism. You can overload a method with different sets of parameters.

Process Isolation

Process isolation is a set of different hardware and software technologies designed to protect each process from other processes on the operating system. It does so by preventing process A from writing to process B.

Multiple Inheritance

While most object oriented languages support inheritance, not all of them support multiple inheritance. ... Multiple Inheritance simply means that a class can inherit properties from more than one base class. In other words, a class can inherit from multiple parent classes -- it's not limited to just one.

Resource

A computer has many resources. A resource can be the memory, disk drive, network bandwidth, battery power, or a monitor. It can also be system objects such as shared memory or a linked list data structure.

Abstract Class

An abstract class is a template definition of methods and variables of a class (category of objects) that contains one or more abstracted methods. Abstract classes are used in all object-oriented programming (OOP) languages, including Java (see Java abstract class), C++, C# and VB.NET.

Domain Separation

Domain separation allows you to separate data, processes, and administrative tasks into logical groupings called domains. ... Domain separation is the paid plugin that enables this configuration. Also like a tenant in a leased building, each domain can have its own set of data that other domains cannot see.

Encapsulation

Encapsulation is one of the fundamental concepts in object-oriented programming (OOP). It describes the idea of bundling data and methods that work on that data within one unit, e.g., a class in Java. This concept is also often used to hide the internal representation, or state, of an object from the outside.

Destructor

Whenever an object is destroyed and removed from memory, the object's destructor is called. In object-oriented programming, a destructor gives an object a last chance to clean up any memory it allocated or perform any other tasks that must be completed before the object is destroyed.

Simplicity

The lack of complexity allows system designers and programmers to identify unwanted access paths.

Open Design

The open-design movement involves the development of physical products, machines and systems through use of publicly shared design information. This includes the making of both free and open-source software as well as open-source hardware.
