Vault
Tool for secrets management and encryption as a service
...Secure, store and tightly control access to tokens, passwords, certificates, encryption keys for protecting secrets and other sensitive data using a UI, CLI, or HTTP API. The shift from static, on-premise infrastructure to dynamic, multi-provider infrastructure changes the approach to security. Security in static infrastructure relies on dedicated servers, static IP addresses, and a clear network perimeter. Security in dynamic infrastructure is defined by ephemeral applications and servers, trusted sources of user and application identity, and software-based encryption. Datacenters with inherently high-trust networks with clear network perimeters. ... -

Algo VPN
Set of Ansible scripts that simplifies the setup of a personal VPN
...If an attacker can compromise a VPN provider, they can monitor a whole lot of sensitive data. Paid-for VPNs tend to be insecure: they share keys, their weak cryptography gives a false sense of security, and they require you to trust their operators. Even if you’re not doing anything wrong, you could be sharing the same endpoint with someone who is. In that case, your network traffic will be analyzed when law enforcement makes that seizure. -

UFW Docker
To fix the Docker and UFW security flaw without disabling iptables
UFW is a popular iptables front end on Ubuntu that makes it easy to manage firewall rules. But when Docker is installed, Docker bypasses the UFW rules and the published ports can be accessed from outside. Almost all of these solutions are similar. It requires disabling docker's iptables function first, but this also means that we give up docker's network management function. This causes containers will not be able to access the external network. It is also mentioned in some articles that you... -
