Manipulating the Networking Environment Using RTNETLINK
RTNETLINK is a simple, yet versatile way of manipulating the networking environment of a Linux host. User-space network protocol handlers are ideal candidates for using RTNETLINK. The advanced IP routing command suite, referred to as IPROUTE2, is based on RTNETLINK. More information about the different operations and flags of RTNETLINK can be found at NETLINK(7) and RTNETLINK(7).

In modern computer systems, privacy and security are mandatory. However, connections from the outside over public networks automatically imply risks. One easily available solution to avoid eavesdroppers’ attempts is SSH. But, its wide adoption during the past 21 years has made it a target for attackers, so hardening your system properly is a must.
Additionally, in highly regulated markets, you must comply with specific operational requirements, proving that you conform to standards and even that you have included new mandatory authentication methods, such as two-factor authentication. In this ebook, I discuss SSH and how to configure and manage it to guarantee that your network is safe, your data is secure and that you comply with relevant regulations.Get the Guide
