Security Testing Service: The Audit of Information Security


Information security audit – is an independent evaluation of the current state of information security system. It establishes the level of compliance with particular criteria and provides results in the form of recommendations.

IS audit allows getting the most comprehensive and objective evaluation of information system security, localize problems and develop an effective IS management system building program organization.

Within the IS audit, or as a separate project, dedicated testers can carry out penetration test service to verify company information system's ability to resist attempts to infiltrate your network and unauthorized exposure to information.

Penetration testing is needed to identify the possible scenario of penetration into the network with the achievement of different goals (capture or administrative rights in the domain database, creating traces of an attacker compromising critical systems).

Penetration testing allows you to get an objective assessment of how easy it is to exercise unauthorized access to resources on the corporate network or website of your company, how, through what vulnerabilities or through any flaws in the system.

Conducting penetration testing allows you to test the level of security systems and the level of maturity of the ISMS.

External penetration test is performed from the public networks and simulates the behavior of the attacker, who attacks from the Internet (using social engineering, and without it). 
External penetration tests vary in scope initially provided information specialist, performing the test.

Integration Testing Software Service & Its Main Approaches


Integration testing software service is aimed to validate the connection between components, and the cooperation of various system parts (operating system, equipment or hookups between various systems).

Integration Testing Levels: 

Component Integration Testing. On the given level, one checks the interaction between system components after component testing has been performed. 
System Integration Testing. The interaction between various systems is checked after the system testing has been executed. 

What are the Continuous Integration Services? 

Continuous Integration (CI) is a practice in software engineering. It’s aimed to provide an immediate feedback about the introduced defect in the code base, which can be detected and eliminated as soon as possible.

Three Approaches to Integration Testing: 

#1. Bottom Up Integration. Software tester gathers all the low-level modules, procedures, and functions and then performs their testing. After these activities, he gathers the next level of modules for integration testing. The given approach is good if all the modules (or nearly all of them) are ready. As well, the given approach helps to define the level of the app being ready, based on test results. 

#2. Top Down Integration. At first, software dedicated tester checks all high-level modules and gradually adds low-level ones. All the modules of lower levels are simulated by plugs with the similar functionality, and then whenever they are ready, they are replaced with real active components. 

#3. “Big Bang” Integration. All or almost all of the developed modules are assembled together as a complete system or its main part, and then tester executes integration testing. This approach is time-saving. But if test cases and their results are recorded in incorrect way – the process of integration testing will be more complicated, and will be an obstacle for the test team in achieving the main goal of integration testing.

Software Test Services: 7 Software Development Models That Should Know Every Tester


Every dedicated tester from an independent testing company knows that depending on the project aims, the development process requires various methods or methodologies. 

Each software development model has different stages and the choice of the model influence the testing process. Program development life cycle involves creating the initial requirements and their refinement, writing code, testing the product and prepare it for release on the market.

7 Software Development Models:  

- Waterfall Model.
- V-Model.
- Incremental Model.
- RAD/Rapid Application Development Model.
- Agile Model.
- Iterative Model.
- Spiral Model.

Each of these models has its advantages and disadvantages, and the choice of model depends on the project type, the amount of work, the competence of developers, available documentation and product requirements.

In next posts, we will analyse all the seven models deeper. Be with us and let's discover software testing world together!
