OPNsense
OPNsense
Simple packet filters are becoming a thing of the past. Even the open-source domain is moving towards Next-Generation Firewalls. And OPNsense is a top player when it comes to intrusion detection, application control, web filtering, and anti-virus. No network is too insignificant to be spared by an attacker. Even home networks, washing machines, and smartwatches are threatened and require a secure environment. Firewalls are a component of the security concept. They protect against known and new threats to computers and networks. A firewall offers the highest level of protection if its functions are known, its operation is simple, and it is ideally positioned in the surrounding infrastructure. OPNsense accepts the challenge and meets these criteria in different ways. This book is the ideal companion for understanding, installing and setting up an OPNsense firewall.Starting Price: Free -

Flatcar Container Linux
Kinvolk
The introduction of container-based infrastructure was a paradigm shift. A Container-optimized Linux distribution is the best foundation for cloud native infrastructure. A minimal OS image only includes the tools needed to run containers. No package manager, no configuration drift. Delivering the OS on an immutable filesystem eliminates a whole category of security vulnerabilities. Automated atomic updates mean you get the latest security updates and open source technologies. Flatcar Container Linux is designed from the ground up for running container workloads. It fully embraces the container paradigm, including only what is required to run containers. Your immutable infrastructure deserves an immutable Linux OS. With Flatcar Container Linux, you manage your infrastructure, not your configuration. -

SCIOPTA
SCIOPTA
The SCIOPTA architecture is specifically designed to provide excellent real-time performance and small size. Internal data structures, memory management, interprocess communication and time management are highly optimized. SCIOPTA is a pre-emptive real-time kernel. Interrupts can be serviced at any time, even inside the kernel. SCIOPTA is a message based real-time operating system. A powerful set of system calls is available to control the resources. Standardized processes and interprocess communication result in clear system designs and are easy to write, to read and to maintain. As processes are communicating with well defined messages and processes can be grouped into modules, SCIOPTA systems are very well suited for team work in big projects. The time-to-market will be reduced dramatically. SCIOPTA is designed on a message based architecture allowing direct message passing between processes. Messages are mainly used for interprocess communication and synchronization. -
