VIDEOS 》 What is purpose of Kernel Development - Example SMOAD Networks SDWAN Orchestrator Firewall Kernel Engine

Often aspiring students may have this question, that what is the purpose of Linux Kernel Development. Since Linux Kernel is very mature and it has almost everything one would need. Usually, we need custom kernel development in the case of any new driver development for new upcoming hardware. And this happens on and on. But at times we may also come across few features/modules/components which are already provided by the Linux Kernel which are not adequate or atleast not the way we exactly intended to use.

Custom Kernel Firewall Engine/Stack for SMOAD Networks:
So here is my video which demonstrates live one such use-case. Such as writing an entire custom Security Layer (a Kernel Firewall Engine/Stack) for SMOAD Networks - who is a Managed SD-WAN Services provider. The idea is to use this engine which is built from scratch, instead using existing Kernel provided Netfilter based Iptables framework. One of the main advantages of this model is that we get complete control over security layer such as Firewall (network security) logs. The logs are further processed so that we dont end up collecting excessive per packet data (something like TCP-Dump/Wireshark). Instead, periodically create a log dump and feed into the database.

Deep Learning, Machine Learning and AI based IDS/IPS:
The security logs can further be fed into a custom Deep Learning or Machine Learning engine driven by AI. And thus extend its feature to support extensive data mining/collection and drive autonomous IDS/IPS engines. This can be driven with or without network admin (human) assisted. This is a complete heterogenous model and so we can avoid third-party dependencies such as Snort/Suricata/etc for IDS/IPS functionality. Since as far as I heard from various industry cyber-security experts, they are often quite bulky, cumbersome and way harder to maintain and configure.

So, this is the real-world example, sometimes no matter what Linux Kernel provides as a part of stock Kernel/OS features, sometimes we have to write our own custom kernel stack or module(s) which can specifically cater our exact needs. So here is my detailed multi-episode Youtube video series on /sysfs Interface.

I also conduct sessions/classes on Systems and Network software programming and architecture. If you are interested, click HERE for more details.

/proc is one of the most popular kernel to user-space interface which you can leverage to add an interface to your Kernel code such as Kernel modules, Kernel Device Drivers, etc. Personally I prefer /proc interface than other alternatives such as /sysfs, ioctl() and so on for my personal Kernel modules/stack. So here is my detailed multi-episode Youtube video series on /sysfs Interface. I also conduct sessions/classes on Systems and Network software programming and architecture.

Roadmap - How to become Systems Software Developer ↗
Friday' 13-May-2022
When you are at the beginning of your career or a student, and aspire to become a software developer, one of the avenues to choose is to become a hard-core Systems Software Developer. However it is easier said than done, since there are many aspects to it as you explore further. As a part of systems developer, you can get into core kernel space developer, kernel device drivers developer, embedded developer and get into things like board bring-up, porting, etc, or can become a user-space systems programmer, and so on. So here is my detailed multi-episode Youtube video series on Roadmap - How to become Systems Software Developer.

Saturday' 13-Mar-2021
Here is a quick reference of important Linux Kernel Data Structures of various assorted Kernel Subsystems such as: Process, Memory Management, Networking, File System, Device Drives, IPC and so on. So when you write custom Kernel code, it is often you may need to populate a new instance of one of these data-structures or just access the existing ones. Hence it is very important to know some of these and get familiarized with. You can bookmark this page, so that you can use this as a quick reference when you write your own custom Linux Kernel Modules.
