The software program provide chain just isn’t linear or simplistic: It’s made up of many various parts launched at totally different occasions and in several phases.
And, at the moment’s software program provide chains solely proceed to develop in complexity — a mixture of proprietary, open-source and third-party code, configurations, binaries, libraries, plugins and different dependencies.
“Organizations and their software program supply pipelines are regularly uncovered to rising cyberattack vectors,” mentioned Michael McGrath, VP of engineering, utility ecosystem at Google Cloud.
Coupled with the “large adoption” of open-source software program, which now powers almost all public infrastructure and is very prevalent all through proprietary software program, “companies world wide are extra weak than ever,” mentioned McGrath.

Thus, it’s crucial for improvement and IT groups to safe provide chains throughout code, folks, techniques and processes — all of which contribute to software program improvement and supply, he mentioned. To assist organizations within the ongoing battle towards cybercriminals, Google Cloud is at the moment unveiling Software program Supply Defend (SDS). The tech big will introduce the brand new end-to-end software program provide chain safety platform at Google Cloud Subsequent ‘22.
In the end, “at the moment’s organizations have to be extra vigilant in defending their software program improvement infrastructure and processes,” mentioned McGrath.
An more and more difficult problem to guard the software program provide chain
A software program provide chain assault happens when a cyberthreat actor infiltrates a vendor’s community and employs malicious code to compromise software program earlier than the seller sends it to prospects, in accordance with the Nationwide Institute of Requirements and Know-how (NIST). This compromised software program, in flip, makes the shopper’s knowledge weak.
In a current research by Anchore, 62% of organizations surveyed had been impacted by software program provide chain assaults. Equally, a research by Argon Safety discovered that software program provide chain assaults grew by greater than 300% in 2021 in comparison with 2020.
Assaults on open-source provide chains are of specific concern, with one report discovering that open-source breaches elevated by 650% in 2021. Moreover, an annual survey by the Synopsys Cybersecurity Analysis Heart revealed that 97% of codebases contained open-source parts. It additionally discovered that 81% of these codebases had a minimum of one recognized open-source vulnerability and 53% contained license conflicts.
Undoubtedly probably the most infamous open-source assaults was SolarWinds, which started in 2020 and compromised enterprises and authorities entities alike — prompting a software program invoice of supplies (SBOM) directive by President Biden. There was additionally the widespread, crippling Log4Shell vulnerability within the Log4j open-source library, which continues to be pervasive.
“Software program provide chain safety is a sophisticated problem,” mentioned McGrath.
He identified that assaults can take “many shapes and kinds” all alongside the software program provide chain, with frequent assault vectors being supply threats, construct threats and dependency threats.
5 vital areas
To assist fight this, the brand new SDS software presents a modular set of capabilities to assist builders, devops and safety groups construct safe cloud functions. The software spans throughout Google Cloud companies, from developer tooling to runtimes like Google Kubernetes Engine (GKE), Cloud Code, Cloud Construct, Cloud Deploy, Artifact Registry and Binary Authorization (amongst others).
Its capabilities cowl 5 totally different areas to guard the software program provide chain:
- Software improvement
- Software program “provide”
- Steady integration (CI) and steady supply (CD)
- Manufacturing environments
- Insurance policies
As McGrath defined, SDS permits for an incremental adoption path in order that organizations can tailor it and choose the instruments greatest suited to their present surroundings and safety priorities.
Shifting safety left
Crucial to SDS is Cloud Workstations, a brand new service that gives absolutely managed improvement environments on Google Cloud. It options built-in safety measures reminiscent of VPC Service Controls (which outline safety perimeters round Google Cloud assets), no native storage of supply code, non-public ingress/egress, pressured picture updates and id entry administration (IAM) entry insurance policies.
This all helps handle frequent native improvement safety ache factors like code exfiltration, privateness dangers and inconsistent configurations, McGrath defined.
With Cloud Workstations, builders can in the end entry “safe, quick, and customizable improvement environments through a browser anytime and anyplace, with constant configurations and customizable tooling,” mentioned McGrath.
On the similar time, IT and safety directors can provision, scale, handle and safe improvement environments on Google Cloud’s infrastructure.
This “performs a key function in shifting safety to the left by enhancing the safety posture of the appliance improvement surroundings,” mentioned McGrath.
SDS additional permits devops groups to retailer, handle and safe construct artifacts in Artifact Registry and detect vulnerabilities with built-in scanning supplied by Container Evaluation. This scans base pictures and now performs on-push vulnerability scanning of Maven and Go containers and for non-containerized Maven packages.
Open-source accountability
One other vital step in bettering software program provide chain safety: Securing construct artifacts and utility dependencies.
“The pervasive use of open-source software program makes this drawback notably difficult,” mentioned McGrath.
To assist handle this, earlier this yr Google launched its Assured Open Supply Software program (AOSS) service, its first “curated” open-source service that goals so as to add a layer of accountability to at the moment’s free or “as-is” open supply. This can be a key a part of SDS, offering entry to greater than 250 curated and vetted open-source software program packages throughout Java and Python, McGrath defined.
These packages are constructed into Google Cloud’s secured pipelines and are “often scanned, analyzed and fuzz-tested for vulnerabilities,” he mentioned.
AOSS additionally routinely generates SBOMs, which stock all parts and dependencies concerned in app improvement and supply and establish potential dangers.
Imposing software program provide chain validation
One other approach that dangerous actors can assault software program provide chains is by compromising CI/CD pipelines.
To handle this, SDS is built-in with Cloud Construct, Google Cloud’s absolutely managed CI platform, and Cloud Deploy, its absolutely managed CD platform. These platforms include built-in security measures together with granular IAM controls, remoted and ephemeral environments, approval gates and VPC service controls. These instruments enable devops groups to higher govern the construct and deployment course of, defined McGrath.
Strengthening the safety posture of the runtime surroundings is one other essential ingredient in defending the software program provide chain. GKE protects functions whereas they’re working; the software options new built-in safety administration capabilities to assist establish safety issues in GKE clusters and workloads, mentioned McGrath.
These embrace detailed assessments, project of severity scores and recommendation on the safety posture of clusters and workloads, he defined. The GKE dashboard now factors out which workloads are affected by a safety concern and gives actionable steering to handle them. These issues are logged and safety occasion data could be routed to ticketing techniques or a safety data and occasion administration (SIEM) system.
In the meantime, Binary Authorization requires pictures to be signed by trusted authorities through the improvement course of, and signature validation could be enforced throughout deployment.
By imposing validation, groups can acquire tighter management over the container surroundings by guaranteeing that solely verified pictures are built-in into the build-and-release course of, defined McGrath.
Google Cloud’s new providing is in response to widespread cries throughout trade, he mentioned. “Improvement and IT groups are all asking for a greater strategy to safe the software program provide chain throughout the code, folks, techniques, and processes that contribute to improvement and supply of the software program,” he mentioned.
