It is a time of ghouls, mischievous spirits, and David S. Pumpkins. In the spirit of Halloween, here are the top five scariest limitations of software composition analysis (SCA) tools that are enough to send shivers down your spine. Read on … if you dare!
1. SCA Scans Only Your Application Code
SCA’s scope is frightfully narrow. When scanning for vulnerable dependencies, SCA only examines your source code even though vulnerable dependencies used to build your software can exist throughout your entire development pipeline. Vulnerable dependencies can be found in dev tools like Jenkins, dev tool plugins like Jenkins Plugins, build modules like GitHub Actions, build module dependencies like GitHub Actions libraries, and infrastructure-as-code (IaC) dependencies. If you’re only scanning application code, you should be shaking in your boots because it is not enough to protect against modern software supply chain attacks like SolarWinds or Codecov.
The good news is that next-gen SCA, pipeline composition analysis (PCA), scans your application code and entire pipeline for vulnerable dependencies. PCA improves upon the foundation of SCA by including a deep understanding of the tools, configurations, processes, activities, components and dependencies used at every stage of the delivery pipeline. When new dependencies like Text4Shell are disclosed, you can be sure every instance of the vulnerability is found and remediated. This way you know you don’t have any proverbial skeletons lurking in your software’s closet.
2. SCA Can’t Tell You Where Vulnerabilities Are Deployed
Vulnerability remediation can be ghoulish. When new high-severity exploits are disclosed, you need to remediate every instance of the vulnerability from all production environments where it could be exploited–and you need to do it fast. Identifying a vulnerability like Log4j in your code base is a start, but you’re not truly secure until you have removed every instance of the vulnerability in production systems where they pose a real risk to your organization. Though traditional SCA can tell you where a vulnerability is in your application code, it has no visibility once that code has been deployed.
PCA gives you visibility into your entire development pipeline, including production environments. This enables you to easily trace the path of a vulnerability from code to deployment locations, such as identifying which Kubernetes clusters contain a specific vulnerability. This enables organizations to be more agile in their response to newly disclosed threats and ensures that every instance of a vulnerability has been remediated.
3. SCA Doesn’t Correlate Risk Across AppSec Engines
Some traditional SCA solutions may be able to collect data from various scanning engines, but they are terrible at making meaningful connections between various data points. Because of this, “traditional” SCA cannot provide the context required to deliver an accurate and nuanced assessment of the impact of one event, nor can it articulate how other related events might compound risk. SCA without context generates too many false positives—this results in your team wasting time chasing ghosts.
PCA correlates risks and threats across all phases of the SDLC as well as from all AppSec scanning tools. By connecting the dots from numerous data sources, PCA helps your security and DevSecOps teams understand holistically how risks relate to each other so they can best tackle the most important security initiatives first.
4. SCA Ignores Pipeline Security and Governance
Modern development pipelines are complex and deeply interconnected–almost as if they are stitched and bolted together like Frankenstein‘s creation. Though managing security policies across the entire SDLC is an arduous and painful task, it is essential if you want to prevent software supply chain attacks. Unfortunately, traditional SCA solutions don’t even come close to helping you manage pipeline security and governance policies like enforcing least privilege or hardening authentication.
Pipeline composition analysis identifies pipeline tooling misconfigurations and helps you implement best practices for security controls across your entire pipeline. Even better, to prevent your tooling from being bypassed, PCA alerts you when pipeline security controls like SCA scanning are removed or disabled.
5. SCA Provides No Visibility into Your SDLC
Traditional SCA solutions focus only on application code. They provide no visibility across your SDLC. They were not designed to scan development and deployment environments, so they cannot secure the later parts of your SDLC. SolarWinds was infiltrated via its TeamCity build server, which traditional SCA tools did not scan. So how can you protect your software supply chain if you can’t see it? Don’t be haunted by SCA tools’ inability to scan the entire SDLC.
Vulnerable dependencies that impact your application can be found across the SDLC. You need to understand all development and deployment tooling–activity, settings, configuration, users and more–to protect your application. Pipeline composition analysis was designed from the ground up to understand your SDLC and bring context to your SCA findings to improve accuracy. It can give you complete visibility into the big picture to cut down on all the noise traditional solutions generate.
Pipeline Composition Analysis: Put Your Nightmares to Rest
While it’s fun to be scared at Halloween, the last thing you want is to be terrified by your AppSec program. When the limitations of traditional SCA solutions threaten to keep you up at night, remember that AppSec innovation requires the ability to do pipeline composition analysis across the entire SDLC, hence the shift from SCA to PCA. PCA plugs all the holes mentioned here, which hopefully can put even the worst nightmares to rest.
