Local Authentication In Insecure Environments

Local Authentication in Insecure Environments

Understanding PKI

PKI (public-key infrastructure) enables the secure exchange of data over otherwise unsecured media, such as the Internet. PKI is the underlying cryptographic security mechanism for digital certificates and certificate directories, which are used to authenticate a message sender. Because PKI is the standard for authenticating commercial electronic transactions,Understanding PKI, Second Edition, provides network and security architects with the tools they need to grasp each phase of the key/certificate life cycle, including generation, publication, deployment, and recovery.

Prometheus Administration and Deployment

"Prometheus Administration and Deployment" "Prometheus Administration and Deployment" is a comprehensive guide that delves into every facet of operating, securing, and scaling Prometheus in modern IT environments. Drawing from the latest architectural best practices, the book methodically articulates core concepts, from Prometheus’ server internals and the sophisticated time series database, to advanced deployment models across traditional, cloud-native, and managed platforms. In-depth chapters walk readers through architecture, dynamic service discovery, query optimization, and remote storage integrations, grounding each topic with pragmatic guidance for real-world implementations. The text excels in bridging practical administration and advanced engineering, with meticulous coverage of provisioning automation, scaling strategies, high availability, disaster recovery, and multi-region observability. Readers will find expert instruction on instrumenting applications, designing custom exporters, optimizing metric schemas, and crafting actionable alerting and notification workflows. The book addresses complex operational realities, including secure multi-tenancy, configuration management, secrets handling, and seamless CI/CD-driven upgrades, facilitating robust governance and reliability at scale. With substantial attention to the observability ecosystem, security, compliance policies, and performance optimization, this book equips professionals to integrate Prometheus within unified monitoring platforms, link metrics with logs and traces, and ensure regulatory adherence in sensitive environments. Blending rigorous technical analysis with actionable playbooks for incident response and troubleshooting, "Prometheus Administration and Deployment" is an indispensable resource for SREs, platform engineers, and architects striving for resilient, secure, and scalable monitoring infrastructures.
