More than half of IT professionals say exploiting security vulnerabilities is the easiest way for criminals to hack into organisations, a survey has revealed.
Most attacks by cybercriminals are targeted at applications, according to 5% of respondents to this year's poll.
Although 73% believe their applications are vulnerable and 55% said security was not a priority for developers, 35% do not check new applications for security flaws.
Application software is always going to contain flaws, according to Peter Wood, chief of operations at penetration testing company First Base Technologies.
"The trick is to catch the mistakes as early as possible, by building security into the entire software development lifecycle", he said.
Businesses should check that software suppliers use developers that are trained in good security practice, said Wood.
"Regular testing throughout the development cycle is also critical, as well as independent testing prior to release," he said.
