Setup HashiCorp Vault on docker

Vault secures, stores, and tightly controls access to tokens, passwords, certificates, API keys, and other secrets in modern computing. Vault is primarily used in production environments to manage secrets. Vault is a complex system that has many different pieces. There is a clear separation of components that are inside or outside of the security barrier. Only the storage backend and the HTTP API are outside, all other components are inside the barrier.

Figure 1: Architecture of Vault and Spring App (Click to enlarge)

The storage backend is untrusted and is used to durably store encrypted data. When the Vault server is started, it must be provided with a storage backend so that data is available across restarts. The HTTP API similarly must be started by the Vault server on start so that clients can interact with it.

// A very rough x64 POC for spoofing environment variables similar to argument spoofing with a focus on
// setting the COMPlus_ETWEnabled=0 var for disabling ETW in .NET.
//
// Works by launching the target process suspended, reading PEB, updates the ptr used to store environment variables,

kafka 集群安全认证配置

本文主要介绍下 kafka 0.10.0 版如何实现sasl/plain认证机制及权限控制

kafka安全机制

kakfa 的安全机制主要分为两部分：

• 身份认证（Authentication）： 对客户端的身份进行认证
• 权限控制（Authorization）： 对topic级别的权限进行控制

kafka 身份认证

kafka 目前支持 SSL，SASL(Kerberos)，SASL（PLAIN) 三种认证机制。
