Distributed Tracing Best Practices

Aggregated on: Thu Sep 14 2023 17:16:44 GMT+0000 (Coordinated Universal Time)

Distributed tracing is now a staple in the modern observability stack. With the shift to microservices, we needed a new way to observe how our services interacted. Distributed Tracing provides that view by allowing us to do request tracing - i.e., trace a request across the components in our distributed system. Today, Distributed Tracing is used for identifying performance bottlenecks, debugging issues, and understanding how our systems are interacting in production. However, implementing Distributed Tracing is complex, and how much value teams get from it depends a fair bit on how it is implemented. Implementation mechanics like which components are instrumented, the sampling rate, and the quality of trace visualization all influence the value companies get from tracing, which in turn influences developer adoption. Additionally, this space is continuously evolving, with new tools and techniques emerging all the time.

Spring Authentication With MetaMask

Aggregated on: Tue Sep 12 2023 23:01:44 GMT+0000 (Coordinated Universal Time)

When choosing a user authentication method for your application, you usually have several options: develop your own system for identification, authentication, and authorization, or use a ready-made solution. A ready-made solution means that the user already has an account on an external system such as Google, Facebook, or GitHub, and you use the appropriate mechanism, most likely OAuth, to provide limited access to the user’s protected resources without transferring the username and password to it. The second option with OAuth is easier to implement, but there is a risk for your user if the user's account is blocked and the user will lose access to your site. Also, if I, as a user, want to enter a site that I do not trust, I have to provide my personal information, such as my email and full name, sacrificing my anonymity. In this article, we’ll build an alternative login method for Spring using the MetaMask browser extension. MetaMask is a cryptocurrency wallet used to manage Ethereum assets and interact with the Ethereum blockchain. Unlike the OAuth provider, only the necessary set of data can be stored on the Ethereum network. We must take care not to store secret information in the public data, but since any wallet on the Ethereum network is in fact a cryptographic strong key pair, in which the public key determines the wallet address and the private key is never transmitted over the network and is known only by the owner, we can use asymmetric encryption to authenticate users.

Why GraphQL API Security Is Unique

Aggregated on: Tue Sep 12 2023 22:01:44 GMT+0000 (Coordinated Universal Time)

Enterprise security teams have had since 2015 to familiarize themselves with GraphQL API security. But many — if not most — still haven’t captured the security nuances of the popular open-source query language. Simply understanding GraphQL’s processes and vulnerable attack vectors isn’t sufficient; it’s also necessary to recognize exploit attempts and nefarious queries (and trigger actions whenever those threats arise). A complete GraphQL security strategy must also be ready to defeat attacks designed to infiltrate GraphQL specifically. A more generalized API security strategy isn’t going to cut it, as headlines continue to prove. Security teams likely have either a web application firewall (WAF) performing active application monitoring to detect threats or a comparable in-house solution that leverages access logs to monitor threat behavior. They also likely depend on specific indicators when monitoring for anomalous activity — including HTTP methods and response status codes, sensitive API routes, and API parameters. Keeping an eye on these indicators can identify attacks where clients try to overwhelm a registration endpoint, perform multiple unsuccessful logins, attempt account enumeration, or tamper with key parameters.

Compliance Automated Standard Solution (COMPASS), Part 6: Compliance to Policy for Multiple Kubernetes Clusters

Aggregated on: Tue Sep 12 2023 20:01:44 GMT+0000 (Coordinated Universal Time)

(Note: A list of links for all articles in this series can be found at the conclusion of this article.) In Part 4 of this multi-part series on continuous compliance, we presented designs for Compliance Policy Administration Centers (CPAC) that facilitate the management of various compliance artifacts connecting the Regulatory Policies expressed as Compliance-as-Code with technical policies implemented as Policy-as-Code. The separation of Compliance-As-Code and Policy-As-Code is purposeful, as different personas (see Part 1) need to independently manage their respective responsibilities according to their expertise, be they controls and parameters selection, crosswalks mapping across regulations, or policy check implementations. The CPAC enables users to deploy and run technical policy checks according to different Regulatory Policies on different Policy Validation Points (PVPs) and, depending upon the level of generality or specialty of the inspected systems, the CPAC performs specific normalization and aggregation transformations. We presented three different designs for CPAC: two for handling specialized PVPs with their declarative vs. imperative policies, and one for orchestrating diverse PVP formats across heterogeneous IT stack levels and cloud services.
