Taking full advantage of all that IT automation and orchestration have to offer frequently involves combining IT infrastructure automation with in-house application development. To this end, open source software is often used to speed development. Unfortunately, incorporating third-party software into your application means incorporating that third-party software’s vulnerabilities, too.
Scanning for, identifying, and patching open source dependencies in an application’s codebase is known as dependency management, and it’s increasingly considered a critical part of modern development. A recent report found that 60% of open source programs audited had a vulnerability that’s already been patched. With 96% of all code using open source libraries, this is a problem that impacts everyone.
There are many dependency management products available; too many to list in a single blog post. That said, we’ll look at some examples of well-known dependency management products that fall into three broad categories: free, open source software; commercial software with a free tier; and commercial software without a free tier.
Some dependency management products rely on open source vulnerability lists (the most famous of which is supplied by the National Institute of Standards and Technology [NIST]). Some products are commercial, and use closed databases (often in combination with the Continue reading

Good day,
The same question arises often about how to leverage DCNM to deploy a VXLAN EVPN Multi-site between traditional Data Centers. To clarify, DCNM can definitively help interconnecting two or multiple Classical Ethernet-based DC networks, in a short time.
As a reminder (post 37) , VXLAN EVPN Multi-site overlay is initiated from the Border Gateway nodes (BGW). The BGW function can run in two different modes; either in Anycast BGW mode (Up to 6 BGW devices per site), traditionally deployed to interconnect VXLAN EVPN based fabrics, or in vPC BGW mode (up to 2 BGW per site), essentially designed to interconnect traditional data centers, but not limited to. vPC BGW can be leveraged to interconnect multiple VXLAN EVPN fabrics from which Endpoints can be locally dual- attached at layer 2. Several designations are used to describe the Classic Ethernet-based data center networks such as Traditional or legacy data center network. All these terms mean that these network are non VXLAN EVPN-based fabrics. The vPC BGW node is agnostic about data center network types, models or switches that construct the data center infrastructure, as long as it offers Layer 2 (dot1Q) connectivity for layer 2 extension, and if Continue reading

Oracle is an Organization Member of the Internet Society. We welcome this guest post announcing a new tool that complements our work to improve the security of the Internet’s routing infrastructure.
We are proud to announce the launch of the IXP Filter Check, which is designed to improve Internet routing security by monitoring route filtering at Internet Exchange Points (IXPs). Here we describe the origin of this project, how it works, and what it hopes to achieve.
Background
Last year, Oracle started partnering with the Internet Society to explore ways to make the Internet safer and more secure for our enterprise customers and users. Businesses – banks, insurance companies, pharmaceutical firms – as well as non-profit organizations and governments continue to turn to Internet-facing assets as key components of their critical infrastructure. Market research firm IDC estimates that 55.9 billion devices will be online by 2025. We believe it is incumbent upon us, as trusted partners and suppliers, to help make the global Internet as safe as possible.
Securing trust-based Internet routing is one such security challenge. Despite decades of research and engineering on the topic, securing Internet routing remains a notoriously difficult task. The challenge is evidenced by the fact that nearly every month there is another major story of a Continue reading

When I first met Cumulus Networks engineers (during NFD9) their focus on simplifying switch configurations totally delighted me (video).
After solving the BGP configuration challenge (could you imagine configuring BGP in a leaf-and-spine fabric with just a few commands in 2015), they did the same thing with EVPN configuration, where they decided to implement the simplest possible design (EBGP-only fabric running EBGP EVPN sessions on leaf-to-spine links), resulting in another round of configuration simplicity.
