Errata Security surveyed professionals with software firms who were attending the RSA Conference and SecurityBSides earlier this month in San Francisco, as well as others online, to gather data on just how far along secure coding practices really are in software companies. Half of the 46 respondents said building secure products is always a concern at their firms, and 81 percent say they are aware of formal secure software development efforts such as Microsoft's SDL, BSIMM, SAMM, and CLASP.
Microsoft's SDL was the most popular tool for secure software development methods, with Microsoft SDL Agile at number two, with 35 percent of the respondents using Agile SDL, most of which were small development firms and several large companies in the survey. "The survey showed a big win for Microsoft's awareness program, but what I hope that Microsoft will learn from this is that small- to medium-sized software companies have different needs than the big guys. SDL-Agile is a good start, but now they need to re-evaluate the resource requirements with small company in mind," says Marisa Fagan, security project manager at Errata Security.
Fagan says among those companies not deploying a secure coding program, the main reason was a lack of resources. "No matter what the size of the company, participants said it was too time consuming, too expensive, and too draining on their resources," she says. "Another reason was that management had deemed it unnecessary...The survey showed that developers look to management to set the security agenda, and are generally not self-starters when it comes to including security in their code."
Chris Wysopal, CTO at Veracode, says the number of survey respondents not using formal secure coding methods doesn't seem low. "Many of these methodologies are fairly new and development organizations move slowly," he says. "Many development organizations don't have the process rigor or the resources to do anything more formal than use one tool or service as part of the development lifecycle."
Steve Lipner, senior director of security engineering strategy in Microsoft's Trustworthy Computing Group, said in a statement that Microsoft was encouraged by some of the survey results. "We are encouraged to see from the Errata Survey results that many companies are taking proactive security measures in their development processes and that the Microsoft SDL and SDL for Agile are being adopted to create more secure software," Lipner said.
Gary McGraw, CTO at Cigital and one of the creators of BSIMM, says BSIMM, a way to measure secure coding initiatives, is often confused with a secure coding methodology or tool: "BSIMM is a measuring stick," McGraw says. "Most organizations involved in BSIMM have their own methodologies." Microsoft, Adobe, and EMC, all BSIMM participants, use their own methods of secure development, for example, he says.
The Errata survey also found that static analysis is the most popular security testing process, with 57 percent of the companies saying they deploy it, followed closely by security code reviews (51 percent); and manual penetration testing (47 percent).
Veracode's Wysopal says the relatively high percentage of static-analysis users may have something to do with the "self-selecting group of leading edge security people attending RSA or Security B-Sides." He says most development teams he talks to don't use static analysis yet formally, but usage is on the rise.
