It is the AppSec practice’s primary responsibility to help custom software development teams understand a customer’s security posture and threat model and implement controls that are consistent with the threat model, assess security features for correctness, track security metrics, and support the team in following an incident response plan. In addition to supporting software delivery teams directly, AppSec engineers may also engage with other groups throughout World Wide Technology to perform vulnerability assessments and penetration testing, and collaborate with senior security consultants to deliver world-class solutions for customers.
