AI assistants are a double-edged sword for builders. On one hand, code-generation assistants have made creating barebones purposes simpler and led to a surge in code pushed to GitHub. But, simply as simple? Producing code with defects and vulnerabilities.
Consequently, application-security groups serving massive growth teams are seeing rising application-vulnerability reviews — a big portion of that are false positives. The truth is, practically a 3rd of groups (31%) discover the vast majority of reported vulnerabilities are false positives, in keeping with software-security agency Snyk’s 2023 State of Open Supply Safety report.
Within the face of rising volumes of code submissions and persevering with issues with false positives, application-security groups are counting on reachability evaluation as an necessary strategy to prioritize their remediation requests. As a result of solely 10% to twenty% of imported code is usually utilized by a particular utility, figuring out whether or not the code is reachable by an attacker — and thus possible exploitable — can dramatically scale back the variety of vulnerabilities that have to be patched, says Joseph Hejderup, technical employees member at Endor Labs, who offered on the subject at SOSS Neighborhood Day Europe 2024 in September. This makes it attainable to prioritize vulnerability reviews, he says.
“With software program composition evaluation — with out trying into the code — we’re basically assuming that when you use this library, you are utilizing all this performance,” Hejderup says. “The place in actuality, we all know that you simply’re solely utilizing a part of the library. By happening to the supply code, you may see whether or not this specific weak a part of the code is used or not used.”
Static utility safety testing (SAST) instruments proceed to evolve and have a confirmed return on funding (ROI), particularly if they’re used to catch software program defects throughout growth time, when the price of fixing a bug is decrease. Nevertheless, false positives scale back the advantages of SAST instruments and undermines the developer belief within the instruments.

False Positives, Lack of Context Stay Issues
General, 61% of builders imagine the sooner cadence of growth with automation has elevated the variety of false positives, in accordance Snyk’s 2023 State of Open Supply Safety report. For application-security groups, discovering methods to scale back the quantity of vulnerabilities found in dozens or a whole lot of initiatives right into a extra manageable burden is important, says Randall Degges, head of developer relations for Snyk.
“Every of these initiatives has a whole lot — possibly 1,000s of vulnerabilities — and a variety of them look scary, like these important RCE vulnerabilities,” he says. “Reachability is known as a good strategy to sort of calm your self down as a safety workforce and never stress your groups out, as a result of when you’re in a position to efficiently filter the vulnerabilities that you simply see based mostly on ‘Are they even being executed, like in our code base or not,’ that is a very large profit to safety groups.”
General, corporations can scale back their remediation work by 60%, simply by excluding non-reachable code. One examine discovered that, whereas 71% of Java purposes include open-source code, purposes solely used about 12% of that code.
Combining reachability with different contextual info — resembling exploitability and enterprise influence — reduces the workload even additional. In an evaluation of 106 million alerts from 900 organizations, a mean of about 118,000 alerts per group, noticed a workload discount of 99.5% — or about 660 alerts per group, in keeping with application-security agency OX Safety.
Reporting fewer vulnerabilities again to builders may also help scale back friction between the 2 teams, says Katie Teitler-Santullo, cybersecurity strategist with OX Safety.
“Lots of the frustration occurs as a result of instruments aren’t in a position to scale back the noise and focus in on the prioritization that builders want [in order] to maneuver on the velocity of growth versus the velocity of safety,” she says.
Supply Code Evaluation or Instrumentation
Sometimes, there are two approaches to reachability evaluation. Static code evaluation centered on constructing graphs of the operate calls within the purposes and figuring out whether or not particular code could also be executed. The dedication is just not all the time easy: A conditional assertion could solely executed as soon as in hundred or 1000’s calls — or by no means — and so application-security instruments have to find out whether or not that constitutes a risk.
Snyk, for instance, errs on the aspect of work-reduction. If there’s a conditional, the corporate’s instruments will ignore the minor branches and simply give attention to the possible final result, says Snyk’s Degges.
“We search for issues the place we will 100% definitively hint it down there, and say that, ‘Sure, that is reachable,'” he says. “The commerce off for that’s that some issues could also be marked as not reachable, despite the fact that they’re. However the profit is that folks do not get a bunch of false alerts.”
One other strategy is to instrument the appliance and the code, to find out at runtime what capabilities are being executed and label that code as reachable.
Whether or not a vulnerability within the code might be exploited is one other degree of investigation, and Endor Lab’s Hejderup expects corporations to give you the option filter all the way down to code that’s reachable and provably exploitable as the following step.
“The sort of extra superior, refined evaluation would possible be the following degree inside reachability evaluation,” he says.
