Five security principles developers must follow` discusses the importance of security in application development, citing a survey of over 1,500 developers and IT decision-makers across Europe. The survey reveals that developers agree to take appropriate precautions when building new applications, with data security being their top concern. However, there is a discrepancy in who holds responsibility for securing an application, with developers pointing towards security specialists or business leaders, while ITDMs believe it lies with the security specialist. To reconcile strong security with delivering utility quickly to users, experts recommend embracing DevSecOps, which involves creating a 'security as code' culture with ongoing collaboration between release engineers and security teams. This approach requires people, process, and technology changes across the application delivery pipeline.
