A Non-Technical Look inside the EXT2 File System
As has been said before, one should make things as simple as possible, but no simpler. The EXT2 file system is rather more complex than most people realize, but this complexity results in both the full set of Unix operations working correctly, and good performance. The code is robust and well tested and serves the Linux community well. We all owe a debt of thanks to M. Card.
Randy Appleton is a professor of Computer Science at Northern Michigan University. He got his Ph.D. at the University of Kentucky. He has been involved with Linux since before version 0.9. Current research includes high performance pre-fetching file systems, with a coming port to the 2.X version of Linux. Other interests include airplanes, especially home-built ones.

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
