Assurance Level Meaning – The Common Criteria for IT Security Assessment (referred to as Common Criteria or CC) is the International Standard (ISO/IEC 15408) for Information and Communications (ICT) Security Certification.
A common criterion is a framework in which ICT users can determine their security and safety requirements (SFRs and SARs, respectively) in a Security Target (ST), and perhaps derived from Protection Profiles (PPs).
Assurance Level Meaning
Developers can then implement or make claims about the security features of their products, and testing labs can evaluate the products based on different levels of security, to find out whether they actually meet the claims. That is, common criteria ensure that the process of specification, implementation and evaluation of an ICT security product is carried out in a rigorous and fundamental and repeatable manner at a level consistent with the target environment for use. Common Criteria maintains a list of certified products, including operating systems, access control systems, databases, and key management systems.

The evaluation process also seeks to establish the level of confidence that can be placed on the product’s safety features through quality assurance processes:
During evaluation, the verbs investigate, examine, report and record are used with the appropriate meaning of CEM.
A statement using this verb identifies what is being evaluated and the properties for which it is being evaluated.
The record shall contain a written description of the processes, events, observations, insights and results in sufficient detail so that the work done during the evaluation can be reconstructed at a later time. for the world. There are different levels of testing, from functionality to acceptance, and each checks specific things to make sure everything is OK.

Well, in short, it is the process of testing whether a program or application is working as it should. Think of it like quality control for your computer programs—you want to catch bugs or problems before they cause problems for the user.
For example, let’s say a new app helps people track their expenses. Testers will run several tests to verify that everything is working properly, such as verifying correct data input. Do all the buttons work? Are users able to navigate the application easily? By running these tests and fixing any issues, developers can ensure that their software is optimized and user-friendly.
A test level, also known as a test level, refers to the various phases or phases of software testing during its development. The main idea behind this concept is that each level of testing focuses on specific aspects of software functionality, allowing for better quality assurance and fewer potential defects.
The most common types of testing levels include – unit testing, integration testing, system testing and acceptance testing. Unit tests focus on individual components, such as methods and functions, while integration tests check whether these components work together correctly. System tests verify that the entire system meets the functional requirements set by stakeholders, while acceptance tests verify software against criteria for their acceptable behavior.

Before software is considered bug-free and ready for deployment it must go through various testing phases. There are generally four levels of software testing, which are discussed below:
Unit testing is performed at the code level, where each component is tested individually to ensure integrity and analyze their functionality. Automated unit tests are possible and highly recommended in today’s fast development environment. To create a unit test, you need to outline what you expect the code to do and write the code, checking if it does what you expect. You should run unit tests to verify that everything works as expected. For example, suppose you have a calculator program that adds two numbers. You can create a unit test that verifies that the numeric values returned by the calculator program are correct. You can also perform tests that verify that content cases and errors are handled correctly.
In this simple example, you can use a unit test to verify that the calculator program can correctly add two numbers.
You can write unit tests that feed these values into the program and check for correct output. For example, you might have a test that checks that the program returns 2 when both 1 and 1 are entered. If 1 and -4 are entered then you can perform another test for the program return -3. When all the tests are written and run, you can confidently say that the calculator program has been successfully tested and works as expected.

Integration testing software enables testers to test group units integrated into systems or subsystems; It helps identify any errors or problems arising from coding errors or integration between modules. It is possible to automate integration testing.
System testing is performed in an integrated environment covering the entire application, where all components are evaluated against specific business requirements. You can use automation tools for system testing.
For example, a no-code test automation platform can complete end-to-end flows for web, mobile and desktop applications and APIs.
Acceptance testing involves testing the functional and non-functional aspects of the system, such as performance, security, usability, accessibility, compatibility, and reliability. Depending on the complexity of the system, this can be done manually or through automation tools. In this example, we will show the process used to automate the acceptance testing of the login page. First, we need to create a test scenario where users enter their login credentials and log in successfully. Automatically detect any page issues and report them to us. Used for acceptance testing, we make sure our login page works as expected and is ready for deployment.

Let’s talk about test sequences. This is a fancy way of saying that we need to test our software step by step. Before we can say our software is ready, we have to go through four main stages of testing.
Software testing is a necessary process. It guarantees that the software will do what it is supposed to and meet all requirements. Skipping testing can lead to serious problems that destroy the usability of the software and how it works. So, don’t forget to devote enough time and resources to testing your software if you want it to be successful when you launch it.
Preliminary testing, also known as zero-level testing, is a key phase of the testing process to identify defects and vulnerabilities in a software system at the earliest possible stage.

Common Criteria (CC) can be considered the fundamental basis of cyber security. All other industry-specific standards have significant overlap with this one. This is also due to its history: it was launched in the early 1990s to create a common international standard and was based on country-specific security standards of the time. Current industry-specific standards in avionics such as DO-356A/ED-203A are based on CC principles.

The CC evaluation level consists of seven levels, with 7 being the highest and 1 being the lowest. The levels are intended to provide reasonable confidence in the IT system and are assigned by independent testing laboratories and government authorities in conjunction with clients seeking certification. The client wants a predetermined level, and the testing lab helps with the certification work. The state authority ultimately issues the certificate. Which software has current certification and which level can be checked at any time at Commoncriteriaportal.org. Only those listed there have certified products.
If one wishes to achieve one of the seven EALs, certain conditions must be met. First, three dimensions of importance in grading embedded systems are scope, depth, and rigor. Scope simply means how big a part of each embedded system (it’s also possible to certify only parts of the embedded system – general criteria gives you the freedom to certify what you want to certify). Depth refers to how well the product is reviewed, how detailed the analysis is. Finally, rigor refers to how rigorously the evaluation is performed. It involves formal proof that something is safe. According to a predefined matrix, classes are listed with sub-families, each of which enhances the goals and requirements for certifying an embedded system. The three dimensions here are compasses for the respective levels of classes. Areas (here called categories) such as development, guidance documents, lifecycle support, security goal assessment (the security goal is the central document where the system integrator validates its efforts), testing and vulnerability assessment are consulted. For example, the Testing class includes Depth (ATE_DPT) and Functional Testing (ATE_FUN) subfamilies. The depth is (ATE_DPT).
