Secure Software Development Lifecycle Overview

STH-WaterfallModel1b
In a previous post, we received a question asking, "what is a secure software development lifecycle"? This is an excellent question, and one that I receive quite often from organizations during an application security assessment.

Let's quickly review the Software Development Lifecycle, also known as the SDLC. The goal of an SDLC is to provide a process for project teams to follow when developing software. A series of steps are completed, each one with a different deliverable, eventually leading to the deployment of functioning software to the

Survey on Application Security Programs - Webcast and Paper

For the second year in a row Jim Bird and I have helped SANS put together a "Survey on Application Security Programs and Practices". We asked some of the same questions as the previous year, just in a different way. Some interesting trends this year, as taken from the executive summary of the soon to be published paper, include the following:


- There was a significant improvement in the number of organizations implementing application security programs and practices. The percentage of organizations that have an active Appsec program increased from 66% last year to 83% this yearand many of the organizations that do not have a program in place yet are at least following some kind of ad hoc security practices.

- Organizations are testing more frequently. In this year's survey, more than one-third are doing continuous, ongoing security testing of their applications, whereas only 23% indicated doing so in our

Security Testing: Less, but More Often can make a Big Difference

Late last year SANS conducted a survey on application security practices in enterprises. One of the questions asked in the survey was how often organizations are doing security testing. The responses were:


  • No security testing policy for critical apps: 13.5%

  • Only when applications are updated, patched or changed: 21.3%

  • Annually: 14.3%

  • Every 3 months: 18.0%

  • Once a month: 9.5%

  • Ongoing: 23.3%


What was most interesting to me is that almost of organizations are doing security testing on an ongoing, near-continuous basis — testing applications as they are being developed or changed.

The only way to test this frequently, and the effective way to scale security testing in large enterprises with thousands of applications and hundreds of web sites, is by relying heavily on
