Quality Assurance Vs Quality Control

Quality Assurance VS Quality Control

In simple words when we compare quality assurance with quality control the quality will be the defects prevention and the goal will be the zero defects for Quality Assurance where as quality will be defect identification and goal will be the process of control to reduce the defects for Quality Control.

§ In Quality Assurance deliverables are created which is performed by a manager or client. Checklist, project audits and methodology and standards are example of QA. Quality control is only about requirements. Quality assurance is basic and does not relate to the specific requirements of the product being developed.

§ Whereas Quality Control is a process in which quality related activities are associated with the creation of project deliverables. Quality control is basically used to verify that deliverables are completed and correct. Inspections, deliverable peer reviews and the testing processes are the examples of quality control. Quality assurance actions are determined before production work begins and these activities are performed while the product is being developed. In contrast, Quality control actions are performed after the product is developed.

QA actions ensure that the process is defined and proper. Methodology and standards development are examples of QA activities. QA would focus on the process elements of a project and requirements are being defined at the proper level of detail. QC activities focus on the finding defects in the deliverables.

Typical QC steps:

· Problem Identification

The main outcome of the Problem Identification stage is to set the overall purpose and objectives of the risk assessment and to determine the likely data requirements

· Problem Analysis

To gather information that helps you determines the nature of a problem encountered on your system.

· Problem Correction

To correct the problem identified in QC process.

· Feedback To QA

Process of control to reduce the defects for Quality Control.

Typical QA steps:

· Data gathering

It is a frequent part of solving problems and satisfying curiosity

· Problem Trend Analysis

Based on number of problems occurring in the area under study

· Process Identification

Each process is identified with a unique name/number.

· Process Analysis

A process can be defined as "a logical series of related transactions that converts input to results or output" (Andersen 1999)

· Process Improvement

It is a series of actions taken by a Process Owner to identify, analyze and improve existing processes

Is Testing a QA or a QC Activity?

Testing is an example of a QC activity, but there are others such as inspections.

The difference is that QA is process oriented and QC is product oriented.

Testing therefore is product oriented and thus is in the QC domain. Testing for quality isn't assuring quality, it's controlling it.

Quality Assurance makes sure you are doing the right things, the right way. Quality Control makes sure the results of what you've done are what you expected.

Example:

Let us consider an example to understand difference between software quality assurance and software control:

“Consider a software project that includes requirements, user Interface design and a SQL database implementation.

The SQA team would produce a quality plan that would specify any standards, processes and procedures that apply to the example project. These might include, by way of example, IEEE xyz specification layout (for the requirements), Motif style guide abc (for the user interface design) and Open SQL standards (for the SQL implementation). All of the standards processes and procedures that should be followed are identified and documented in the quality plan, this is done by SQA.

When the requirements are produced (in this example) the Software Quality Control team would ensure that the requirements did in fact follow the documented standard (in this case IEEE xyz). The same task, by SQC, would be undertaken for the user interface design and the SQL implementation, that is they both followed the standard identified by SQA. Later the SQA team could make audits to verify that IEEE xyz and not IEEE abc was indeed used as the requirements standard”.

In this way a difference between correctly implemented by SQA and followed by SQC can clearly be drawn.

The SQC definition implies software testing, as this is part of the project produces the required internal and external (deliverable) products definition for SQC. The term required refers not only to the functional requirements but also to the non-functional aspects of supportability, performance and usability etc. All of the requirements are Verified or Validated by SQC. For the most part, however, it is the distinction around correctly implemented and followed for standards, processes and procedures that gives the most confusion for the SQA and SQC definitions. Testing is normally clearly identified with SQC, although it is usually only associated with functional requirement testing.

What is Email Security?

Viruses transmitted via emails are very common and cannot be avoided by using only antivirus software. Some additional checks need to be carried out to protect email vulnerabilities.

Love Letter is the most harmful type of viruses transmitted in email and causes great loss within minutes in the email systems and corporate networks. Some viruses are sent via attachments while some are sent using the messages within the emails that run automatically. “Nimda” is an example of such virus that runs automatically i.e. don’t require intention of the user.

An email containing infected attachments entails with malformed MIME headers, and HTML mails with embedded scripts should be found in the emails to protect email system from current and future viruses. There are various tests that should be conducted in order to secure email system from the email vulnerabilities. Some of them are as under:

· Long subject attachment checking bypass test

Checks whether system accepts emails with long subjects.

· Attachment with no filename vulnerability test

Examines whether system accepts an attachment with no filename containing executable code that can bypass content checking security solutions.

· Long filename vulnerability test

Indicates whether system blocks emails with attachments having long filenames, which can be used to trick a user into double-clicking the attachment, which can execute the malicious code it contains on the system.

· Popup Object Exploit vulnerability test

Discover if machine is vulnerable to the Popup Object Exploit which can automatically launch files on a vulnerable system.

· Double file extension vulnerability test

Shows whether email system accepts emails which contain attachments with double file extensions.

· ActiveX vulnerability test

Finds out if machine is vulnerable to the ActiveX exploit.

· CLSID extension vulnerability test

Reveals whether mail server detects and blocks files with Class ID (CLSID) extensions.

· CLSID extension vulnerability test

Reveals whether Outlook 2002 (XP) system detects and blocks files with Class ID (CLSID) extensions.

· Eicar anti-virus software test

Check if anti-virus software is in place and functioning correctly.

· Fragmented message vulnerability test

Checks whether server-level anti-virus/content checking system detects and blocks emails using the fragmented message exploit.

· GFI's Access exploit vulnerability test

Discover if machine is vulnerable to the Access exploit vulnerability discovered by GFI. It does not apply to IE6 users who have the latest patches installed.

· Iframe remote vulnerability test

Discover if machine is vulnerable to the Iframe remote exploit. It does not apply to IE6 users who have the latest patches installed.

· Malformed file extension vulnerability test

Examines whether Outlook 2002 (XP) system detects and blocks files with malformed HTA file extensions.

· MIME header vulnerability test (Nimda & Klez testing)

Examines whether system is protected against emails using the MIME exploit. It does not apply to IE6 users who have the latest patches installed.

· Object Codebase vulnerability test

Examines whether system detects and blocks emails using the Object Codebase exploit. It is also suited to Outlook 2002. It does not apply to IE6 users who have the latest patches installed

· VBS attachment vulnerability test

Checks whether mail server blocks VBS attachments.

If you are alarmed by these vulnerabilities, there exist solutions. Look out for companies ask for name and email address to sign up in order to check email system against all these vulnerabilities. On signup an email is send containing the link for confirmation. After the confirmation the email testing is performed on the system and results are send back in email.

Software Performance Testing

Performance Testing measures the effectiveness of the computer, network or any software application. Quantitative and qualitative testing is conducted to verify the performance of a software application. Quantitatively the application is tested for the response time upon certain input and qualitatively it’s checked for reliability, scalability and interoperability. To check the performance, stress testing is also performed to identify the stability of an application under certain level of load. It’s also checked if the application is self recoverable of not if treated beyond its threshold.

Performance Testing is conducted by using various tools like JMeter, LoadRunner, AstraLoad and WAPT. Performance parameters are defined for the application and results are analyzed on the basis of these parameters like “Response Time”, “Throughput”, “Transfer Rate” to name a few.
