The Story of a Simple and Dangerous Kernel Bug
by Răzvan Musăloiu-E.
Among other things, the update for Mac OS X 10.5.8 also fixed an interesting kernel bug related to the way the fcntl call is handled. The bug was identified as CVE-2009-1235 and the first exploit seems to be from June 2008. The variant that I discovered is much simpler and is, as far as I know, the one that really convinced Apple to solve the issue. :-) The oldest kernel I was able to test the problem was Darwin 8.0.1...
Software testing offers big ROI
By Jennette Mullaney, Associate Editor
Calculating the Software Testing ROI.
Software testing is an expense that ultimately saves an organization a great deal of money. It has a quantifiable return on investment (ROI) and testers can follow a simple series of steps to calculate it, explained Rex Black during a session at the recent FutureTest 2008 conference.
Black, president and principal consultant of RBCS, emphasized the cost-effectiveness of...
Closer View at the Software Testing Company.

The Importance of Automated Software Testing
by Fred Hapgood
As complicated as our relationship with computers has been during the past half-century, there is at least one constant: Wherever you find a computer you will find a swarm of bugs. For decades users and managers have searched for weapons to use against infestations. Some try structured programming tools, environments supposedly too sterile for bugs to breed. Others rely on ambitious alpha and beta testing programs. But conceptually...
What is Penetration Testing?
What is a penetration test?
Much of the confusion surrounding penetration testing stems from the fact it is a relatively recent and rapidly evolving field. Additionally, many organisations will have their own internal terminology (one man's penetration test is another's vulnerability audit or technical risk assessment).
At its simplest, a penetration-test (actually, we prefer the term security assessment) is the process of actively evaluating your...
The importance of software testing strategy.
The software testing strategy is an essential process that comprises part of the software development lifecycle. Companies that fail to implement quality control standards and adequately define the range of tests for an application can destroy brand credibility, sabotage the overall project and create a cost blowout.
The test plan forms part of the project documentation. The goals, objectives and functional requirements of a software application...
My Code Has no Bugs!
From Alex Rosiu.
Even though it is practically impossible to write bug-free source code, some people really think they do.
It was the case of one of my former colleagues from a company for which I have worked for a couple of years. He was really thinking that he was extremely skilled (and he was… but not as much as he thought), which unfortunately for him, has led him to adopt a quite arrogant and distant attitude towards everybody. And I...
What is Software Testing ?
What is Software Testing?
Testing involves operation of a system or application under controlled conditions and evaluating the results (eg, 'if the user is in interface A of the application while using hardware B, and does C, then D should happen'). The controlled conditions should include both normal and abnormal conditions. Testing should intentionally attempt to make things go wrong to determine if things happen when they shouldn't or...
Software Testing and fusions: unifying convenience with profitability
The news of the fusion of the two giants Itaú and Unibanco shaked the Brazilian economic area, and reactivated the discussion: if in fact, mergers/fusions work. Apparently, the answer is positive in the country. According to Associação Nacional dos Bancos de Investimento (Anbid), only in 2008 74% of mergers performed in...
