While most IT and security leaders believe that application security problems are inherently more risky than network security issues, appsec still doesn't get near the same kind of executive support and technical visibility that network security does, a new study out this week by Ponemon Institute shows. Fortunately, new trends in IT delivery like DevOps and continuous integration are making it possible to meet application security challenges that have hampered progress in the past.
Examining the attitudes and practices of over IT leaders and practitioners, "Application Security in the Changing Risk Landscape" found that the majority of them believe the frequency and severity of attacks against the application layer are greater than against the network layer. Sponsored by F5 Networks, the study reports that 50% of respondents agreed that applications are attacks are more frequent and 58% agreed they are more severe.
The most commonly cited reasons that application-layer attacks are worse than network-layer attacks were that they're harder to detect and more difficult to contain. According to those surveyed, a lack of visibility in the application layer is the top barrier to achieving a strong application security posture.
In spite of the risks and challenges, application security still gets lackluster funding and support. The study shows that only 35% of respondents believe they have ample resources to detect vulnerabilities and 30% say they have enough resources to remediate those vulnerabilities. On average, the network security budget is more than double the application security budget across respondents' organizations.
In spite of a decade plus of strong advocacy for improved testing and mitigation practices within the security industry, most organizations still struggle to test regularly. A quarter of organizations still do no application testing for vulnerabilities at all, and another 33% have no pre-scheduled testing or only test annually. What's more, it appears that many organizations--about a third of them--largely depend upon the stop-gap measure of utilizing web application firewalls as their primary means of securing applications.
One of the years-long difficulties that have hamstrung efforts to improve application security is that of accountability, due to the large number of stakeholders involved in developing, delivering, and operating software.
"Fifty-six percent of respondents believe accountability for application security is shifting from IT to the end user or application owner," the report said. "However, at this time responsibility for ensuring the security of applications is dispersed throughout the organization."
The shift to DevOps and continuous delivery pipelines could go a long way toward automating testing and moving responsibilities closer to the developer so that testing can be done earlier and in a more incremental fashion. About 71% of those surveyed believe that DevOps and continuous delivery stand to improve application delivery. The trick will be in how well testing procedures and technology can be streamlined into the overall automated testing framework.
"I believe that DevOps practices can be highly beneficial to application security as long as security testing is embedded into the automated testing we already do in DevOps to ensure that the apps we develop are both functionally robust and secure from the ground up," says Mike Convertino, CISO for F5.
