Testing software during the development phase has become an important part of the development lifecycle and is key to the agile methodologies. Code quality and maintainability is increased by adopting an integrated testing strategy that stresses unit tests, integration tests and acceptance tests throughout the project. But these tests are ...

A server functionally or physically dedicated to the task of running Guest OSs. VMWare ESX is an example of the latter, as the host software is custom-designed only to run Guest OSs as quickly and efficiently as possible. ESX benefits from the performance advantages of functioning as both the VMM ...

The Java runtime keeps track of the sequence of Java calls that are made as a program executes. When access to a protected resource is requested, the entire call stack, by default, is evaluated to determine whether the requested access is permitted. As mentioned earlier, resources are protected by the SecurityManager. ...

The access control architecture in the Java platform protects access to sensitive resources (for example, local files) or sensitive application code (for example, methods in a class). All access control decisions are mediated by a security manager, represented by the java.lang.SecurityManager class. A SecurityManager must be installed into the Java ...

The data that travels across a network can be accessed by someone who is not the intended recipient. When the data includes private information, such as passwords and credit card numbers, steps must be taken to make the data unintelligible to unauthorized parties. It is also important to ensure that ...

There are two built-in tools for working with keys, certificates, and key stores: keytool is used to create and manage key stores. It can Create public/private key pairs Display, import, and export X.509 v1, v2, and v3 certificates stored as files Create ...

The Java language is designed to be type-safe and easy to use. It provides automatic memory management, garbage collection, and range-checking on arrays. This reduces the overall programming burden placed on developers, leading to fewer subtle programming errors and to safer, more robust code. In addition, the Java language defines different ...

The Java platform provides for long-term persistent storage of cryptographic keys and certificates via key and certificate stores. Specifically, the java.security.KeyStore class represents a key store, a secure repository of cryptographic keys and/or trusted certificates (to be used, for example, during certification path validation), and the java.security.cert.CertStore class represents a ...

The Java cryptography architecture is a framework for accessing and developing cryptographic functionality for the Java platform. It includes APIs for a large variety of cryptographic services, including Message digest algorithms Digital signature algorithms Symmetric bulk encryption Symmetric ...

The Java platform defines a set of APIs spanning major security areas, including cryptography, public key infrastructure, authentication, secure communication, and access control. These APIs allow developers to easily integrate security into their application code. They were designed around the following principles: Implementation independence Applications do not need to implement security themselves. ...

If you use Ajax within your Web application, its overall complexity will greatly increase, and each server side function will be an additional target for attackers. Here are five steps you can take to decrease these threats: The key coding discipline of never trusting the client still ...

Application development experts assume that making their software more secure increases the cost of tools and lengthens the time it takes to get an app out the door. That isn't necessarily true, according to studies from Gartner and others, which show that integrating security best practices into the software dev ...
