Patreon users download the PDF version. All Linux and Unix servers are managed manually or by automation tools such as Ansible using ssh. For example, say you have a server at Linode or AWS. Then you copy your public ssh key to a remote cloud server. Once copied, you can now login to those servers without a password as long as ssh keys are matched. It is the best practice. Unfortunately, you are not protecting ssh keys stored on a local desktop or dev machine at $HOME/.ssh/ directory. If your keys are stolen, an attacker can get access to all of your cloud servers, including backup servers. To ..read more

As you may know, email spoofing allows attackers to pose as someone else to gain illegal profit. For example, I only use webmaster@cyberciti.biz for communication, but someone might create a spoofed-up email, say info@opensourceflare.com, to trick someone. This is called email spoofing with fake headers as follow: Date: Thu, 24 Oct 2021 12:46:10 From: nixCraft <info@opensourceflare.com> Reply-To: info@opensourceflare-email.com To: <my@personal_gmail_com> Correct headers are often not checked by receiving email servers, and my@personal_gmail_com may think the email is from me.

usbgurd You deployed a perfect firewall and other network security policies preventing unauthorized access to the user's desktop computer over a network. However, you still need to block USB device access. We can configure a Linux desktop security policy to protect your computer against rogue USB devices (a.k.a. BadUSB) by implementing essential allow and blocklisting capabilities based on device attributes. For instance, I can define what kind of USB devices are authorized and how a USB device interacts with the Linux system. For example, I can define policy allowing Yubikey with serial numb ..read more

Like every other solo developer and sysadmin, I do stuff using ssh. Some stuff is automated using scripts, and others require ssh login. For example, one of my scripts logs into my Linux and FreeBSD server using public ssh keys and does a particular type of work for me. I have a dedicated user account for that purpose called autovivek on Raspberry PI 4 for Ansible and custom script automation. Here is how it works: {rpi4:~}$ ssh autovivek@192.168.2.17 /path/to/taks1 In other cases, it sends scripts and then executes them on the remote server named 192.168.2.17. Sounds good, right? So, when I ..read more
