Protect your software supply chain end-to-end. Devs can ensure that open-source components, CI/CD workflows, and release pipelines are safe. Plus, the SOC gets greater visibility of the entire build process, bolstering your organization's last line of defense.
Supply chain attacks are an emerging threats that target software developers and suppliers. The goal is to access source codes, build processes, or update mechanisms by infecting legitimate apps to distribute malware.
Because software is built and released by trusted vendors, these apps and updates are signed and certified. In software supply chain attacks, vendors are likely unaware that their apps or updates are infected with malicious code when they're released to the public. The malicious code then runs with the same trust and permissions as the app.
Our study of over 65,000 applications also revealed that managed software supply chains are safer. We measured a 55% reduction in the use of vulnerable open-source components in companies that managed their open-source software supply chains.
SLSA levels are like a common language to talk about how secure software, supply chains and their component parts really are. From source to system, the levels blend together industry-recognized best practices to create four compliance levels of increasing assurance. These look at the builds, sources and dependencies in open source or commercial software. Starting with easy, basic steps at the lower levels to build up and protect against advanced threats later, bringing SLSA into your work means prioritized, practical measures to prevent unauthorized modifications to software, and a plan to harden that security over time.
Whether you're just looking to deploy a basic contract (opens new window) or you're ready to build a cross-chain app, you'll be able to find everything you need to start building on Optimism within this section.
We've got detailed guides for that.If you want to bridge a token from Ethereum to Optimism (or vice versa!), you should learn more about our Standard Token Bridge.The Standard Token Bridge makes the process of moving tokens between chains as easy as possible.
If you're looking for something more advanced, we recommend reading through our page on sending data between L1 and L2.Contracts on one chain can trigger contract functions on the other chain, it's pretty cool!We even dogfood the same infrastructure and use it under the hood of the Standard Token Bridge.
Document chaining is navigating from one qlikview application to other. While doing that we can optionally pass the selection from the first application to the other. You can do it by setting an action either in text object or button to open a qlikview application.
However, open source solutions, especially initiatives with active communities of engineers, can provide excellent support and frequent updates by leveraging the collective wisdom of an engaged user base of coders and engineers as well as enabling a level of transparency that cannot be achieved with proprietary solutions. This is especially true of products that protect software supply chains, as DB Schenker discovered when we looked to increase security awareness within our Kubernetes clusters.
We first looked at Notary to manage and sign Docker image metadata, but it was incredibly complicated to set up and maintain. There is too much logic directly tied to the docker cli and the key management needs to be handled either within the notary tooling or manually. We would need to build a new chain of trust only for the sake of notary as it does not integrate well with Hashicorp Vault, which we use as a KMS and primary trust anchor. The automated integration in a Kubernetes admission hook seems also not that common, which started our search for alternative solutions.
DEV-0569 has used varied infection chains using PowerShell and batch scripts that ultimately led to the download of malware payloads like information stealers or a legitimate
