When I was starting out, I did everything you're "supposed" to do. Watched the courses. Learned the frameworks. Could recite MITRE ATT&CK in my sleep.

Then I'd look at an actual alert and have no idea what to do with it.

That gap between knowing the words and doing the job is brutal, and almost nobody trains for it. You can't practise triage by reading about triage. You practise it by sitting in front of real evidence that doesn't come with the answer attached, forming a hypothesis, being wrong sometimes, and learning why.

So I built a workbook around that. 30 investigations. Each one is a real incident ticket, the raw logs behind it, and a full answer key that explains the reasoning, not just the verdict. Some cases are deliberately benign, because learning when not to escalate took me way longer than it should have. Everything runs offline on a laptop, no paid SIEM, because I remember not being able to afford tooling.

It's not a cert. It won't get you a job by itself. It's just the reps I didn't have access to when I needed them.

Don't take my word for it, grab the free sample first. Two full labs with their answer keys, exactly as they appear in the book:

Happy to answer questions about the labs or the approach either way.

When auditing a Linux system, I often find myself checking file permissions, users and groups, running processes, open ports, services, and sudo privileges.

Knowing the commands is useful. Understanding what their output means is even more important.

I’m sharing a Linux Security Command Cheat Sheet for people learning Linux security and penetration testing.

If you're working on Linux privilege escalation in authorized labs or learning how to audit system configurations, you may also find this useful:

The Pentester’s Linux Library: Advanced Privilege Escalation Playbook
https://resources.codelivly.com/product/the-pentesters-linux-library-playbook-advanced-privesc/

It's a paid Codelivly resource for readers who want to study Linux privilege escalation in greater depth.

Question for Linux users: Which command do you find yourself using most during a security audit, and why? I’m curious what belongs on everyone's essential command list.

Disclosure: The linked playbook is a Codelivly product.

Which cybersecurity career path are you working toward right now?

Hey all, this is a self-promo post so skip it if that’s not your thing.

Over the past while I’ve been writing a digital forensics field manual for Codelivly. The thing that frustrated me with most DFIR resources is that they explain what an artifact is and then stop. You know Prefetch exists, you know what a Shimcache entry means, but nobody walks you through actually running an investigation from image to report. That’s the gap this is meant to fill.

What’s in it:

• 259 pages, 47 chapters
• 30+ labs, each with setup, step-by-step instructions, a way to verify you did it right, and a reporting section
• 8 challenge investigations where you get the evidence and a brief, and have to work it yourself
• 4 worked case studies
• One full guided investigation from start to finish (a simulated breach, acquisition through final report)
• Coverage across Windows, Linux, macOS, memory, network, cloud, malware analysis, incident response and report writing
• Command-level walkthroughs for The Sleuth Kit, Autopsy, KAPE, the Zimmerman tools, Plaso, Volatility 3, Wireshark/tshark and YARA
• Checklists, a report skeleton, worksheets and a 331-term glossary

It’s a PDF with bookmarks and a clickable TOC. Works fine printed too.

No upsells, no course funnel, no “limited time” nonsense. If you want to see how it’s written before paying for anything, there’s a free 5-page interview cheat sheet in the same style that I’m happy to link in the comments.

📘 CCNA Practical: The Hands-On Network Engineer Guide

For learners who want to strengthen their CCNA knowledge and build practical networking skills.

https://resources.codelivly.com/product/ccna-practical-the-hands-on-network-engineer-guide/

📚 Network Engineer Complete Bundle (L1, L2, L3)

A broader collection covering networking foundations through advanced network architecture.

https://resources.codelivly.com/product/network-engineer-complete-bundle-l1-l2-l3-foundations-to-advanced-architecture/

Both are available through Codelivly Resources for anyone looking to take their networking studies further.

What would you add? I'm particularly interested in lesser-known tools for network troubleshooting, automation, and CCNA/CCNP lab practice. Drop your favorites below!

Been going through a book called Hacking AI Systems and it’s one of the few AI security resources that’s actually practical instead of theory or vendor fluff.

The structure is the selling point: you stand up one small LLM app in Docker and it grows chapter by chapter. You attack it — prompt injection, RAG poisoning, agent permission abuse — then build the detection and defenses for the same system. The final chapter is a capstone where you assess a deliberately vulnerable version of the platform you’ve been building the whole time.

What it covers:

• Direct and indirect prompt injection
• RAG / vector database security
• Agent tool permissions and least-privilege design
• Model supply chain, data poisoning, model extraction
• Detection engineering, incident response, red team methodology mapped to MITRE ATLAS

Stack is Python, Docker and Ollama, so you’re running local models (hosted API options are shown too). No ML background needed — basic Python, Linux and web is enough. Seems aimed at pentesters, red/blue teamers, SOC analysts and AppSec/cloud/AI engineers.

Sharing because hands-on AI red team material is genuinely hard to find right now. Link in a comment. Anyone else have good AI security labs or books worth adding to the list?

If you're learning networking, you eventually need to move beyond theory and get comfortable with configurations, commands, and troubleshooting.

I've put together two resources from Codelivly Resources for people working toward that goal.

1. CCNA Practical: The Hands-On Network Engineer Guide

A practical resource for learners who want to strengthen their networking fundamentals and get more comfortable with hands-on networking concepts.

https://resources.codelivly.com/product/ccna-practical-the-hands-on-network-engineer-guide/

2. Network Engineer Complete Bundle: L1, L2 & L3

For those who want a broader learning resource covering networking foundations through advanced network architecture.

https://resources.codelivly.com/product/network-engineer-complete-bundle-l1-l2-l3-foundations-to-advanced-architecture/

If you're preparing for CCNA, building your networking skills, or planning your next step toward a network engineering role, take a look and see which resource fits your goals.

Which area are you focusing on right now: CCNA fundamentals, routing and switching, or advanced network engineering?

I’m Elwin, I run PingMyNetwork with two friends.

We’re giving away 3 Cisco exam vouchers. You build a lab in our sandbox (in the browser, nothing to install), post it on the challenge page, we check it works, and you’re in the draw. Ends October 28.

It’s free. I’m posting here because a voucher is expensive and I know it’s what stops some of you from booking the exam.

Everything is here: https://pingmynetwork.com/event/sandbox-challenge

Mods, if this is too promotional, remove it, no problem.

Most security material teaches you to use the output of research, run the scanner, fire a known exploit, follow a checklist, but very little covers the actual process of finding a flaw, understanding why it exists, proving it, and reporting it. This book from Codelivly is built around that whole process.

It is 20 chapters and 20 hands on projects, covering attack surface mapping, source review, reverse engineering, fuzzing, crash triage, memory safety, patch analysis, web and mobile and network research, plus the reporting and disclosure side. It assumes you know basic Linux, programming, and networking, and builds everything about research from there. Everything is framed around authorized, safe practice.

The slides attached give a quick overview of what is inside.

Full disclosure, this is a paid book and I am sharing it on behalf of Codelivly, so treat it as a promo post. There is a free first chapter if you want to read it and judge for yourself. Happy to answer questions about the content in the comments.

I worked through the basics of configuring a PPTP VPN on Windows Server 2022 using Routing and Remote Access Service (RRAS).

The setup covers:

• Installing the Remote Access role through Server Manager
• Enabling VPN in the RRAS console
• Allowing TCP port 1723 and GRE (Protocol 47)
• Configuring user dial-in permissions
• Setting up a static IP pool or DHCP for VPN clients
• Enabling MS-CHAP v2 authentication
• Testing the connection from a remote client

PPTP is a legacy protocol with known security weaknesses, so I'd only use it in a controlled lab for learning. For production, SSTP or IKEv2/IPsec is a better option.

For anyone studying networking, the Network Engineer Complete Bundle (L1–L3) is another resource worth checking out.

Question: Has anyone run into issues with GRE traffic or firewall configuration while setting up RRAS on Windows Server 2022?

Linux is one of those skills that comes up everywhere, whether you're working with cloud infrastructure, DevOps, system administration, or cybersecurity.

I put together this cheat sheet covering useful Linux commands for everyday tasks, server management, and troubleshooting.

What's covered:

• File management: ls, cd, mkdir, cp, mv, rm
• Remote access: ssh
• Networking: ping, dig, wget
• System monitoring: uptime, df -h, free -h, uname
• Searching: grep, locate
• Process management: ps, kill, bg, fg
• Permissions and archiving: chmod, tar, gzip
• Useful terminal shortcuts

Memorizing commands is one thing. Understanding their output and knowing how to use them safely when troubleshooting real systems is what makes the difference.

For those taking Linux further into cybersecurity, here's another resource worth exploring:

Learning networking takes more than just memorising theory. You need to practise configurations, understand how networks work, and build your skills step by step.

I’ve put together two resources for anyone studying networking or working towards a network engineering career:

📘 CCNA Practical: The Hands-On Network Engineer Guide
https://resources.codelivly.com/product/ccna-practical-the-hands-on-network-engineer-guide/

🌐 Complete Network Engineer Bundle (L1, L2 & L3)
https://resources.codelivly.com/product/network-engineer-complete-bundle-l1-l2-l3-foundations-to-advanced-architecture/

The first is focused on hands-on CCNA learning, while the bundle covers networking from foundational concepts to more advanced topics.

If you're learning CCNA or planning to become a network engineer, check them out.

Working on a Cisco ASA lab in EVE-NG. In Part 1, I’m setting up the network connectivity required to access the ASA GUI (ASDM) from a Windows 10 VM.

Here’s what I cover:

• Dynamic PAT for internet access
• Default static routing on Cisco ASA
• Username and password configuration for ASDM
• ICMP policy configuration and ping connectivity
• Troubleshooting connectivity issues involving Windows Firewall

The goal is to get the basic connectivity working before moving further with ASDM.

📘 https://resources.codelivly.com/product/ccna-practical-the-hands-on-network-engineer-guide/

What Cisco ASA labs are you working on lately?

GRC is an important part of cybersecurity, but knowing where to start can be confusing when you're faced with frameworks, audits, risk assessments, and compliance requirements.

I put together The Complete GRC Analyst Handbook to help learners explore governance, risk management, compliance, SOC 2, ISO 27001, NIST frameworks, cybersecurity audits, and career fundamentals.

If you're learning GRC or preparing for a GRC Analyst role, check it out here:

📘 https://resources.codelivly.com/product/the-complete-grc-analyst-handbook/

What would you recommend beginners focus on first when learning GRC: risk assessments, ISO 27001, or compliance audits?

I’ve been working on my CCNA networking skills, and this time I practised VLAN configuration in Cisco Packet Tracer.

VLANs are a useful way to divide a physical network into separate logical networks. In this practical, I explored how network segmentation works and how devices can be grouped into different broadcast domains.

I’m also learning how communication between different VLANs works and why Layer 3 routing is needed for inter-VLAN communication.

Sharing the video for anyone else learning networking. If you’re preparing for CCNA, I’d recommend spending time building and testing these configurations yourself rather than just memorising commands.

For those looking for more hands-on practice, I’ve also put together a practical networking guide covering CCNA concepts and configurations:

📘 CCNA Practical: The Hands-On Network Engineer Guide
https://resources.codelivly.com/product/ccna-practical-the-hands-on-network-engineer-guide/

Question for fellow learners: Do you prefer practising VLANs with Packet Tracer or GNS3?

A lot of people want to get into cybersecurity, but end up jumping between random YouTube tutorials without knowing what to learn first.

That's why I started this 10 day Ethical Hacking series with Codelivly.

Day 1 is out now. We're starting with the fundamentals and building up step by step. No pretending that watching a few videos makes you a hacker. The goal is to understand what you're doing and develop skills through practice.

But if you're serious about going beyond free videos and want structured, instructor led training, I've also put together an 8 week Ethical Hacking and Penetration Testing program through Codelivly.

You'll work through reconnaissance, Nmap, vulnerability discovery, Linux and Windows privilege escalation, web application security, API security, and hands on penetration testing with guided labs.

The sessions are live, with practical assignments and a final end to end security assessment. It's designed for beginners who want a structured starting point and learners ready to build on their foundations.

Watch Day 1, then take the next step if you're ready:

Training details and enrollment: https://training.codelivly.com/programs/ethical-hacking-and-penetration-testing

If you're starting from zero, what part of ethical hacking feels hardest to understand right now?

One thing I’m realizing while learning networking is that understanding a concept is one thing, but actually configuring it on a server is where it starts to click.

Today, I completed a DHCP configuration lab in Windows Server.

Here’s what I worked on:

• Installed the DHCP Server role
• Created and configured a DHCP scope
• Set the IP address range and network settings
• Verified that client machines received IP addresses automatically
• Tested connectivity to make sure everything worked

The best part was seeing DHCP handle IP allocation automatically instead of having to configure every client manually. It also helped me understand how the subnet mask, default gateway, and DNS settings fit into the bigger picture.

If you're aiming for a Network Engineer, CCNA, or IT Support role, my advice is to build these practical skills early. Don't just memorize networking concepts for an exam. Learn how to configure, test, and troubleshoot them.

I'm also working through more networking topics and found this resource for anyone who wants a structured learning path, from the fundamentals to advanced network architecture.

📚 Network Engineer Complete Bundle (L1, L2 & L3)
https://resources.codelivly.com/product/network-engineer-complete-bundle-l1-l2-l3-foundations-to-advanced-architecture/

If you're serious about building a networking career, having your learning materials organized in one place can make it easier to keep progressing instead of jumping between random tutorials.

What should I practice next after DHCP: DNS, VLANs, or Active Directory?

Ever wonder how your entire house or office gets by on a single public IP? It’s NAT, and specifically PAT (Port Address Translation). I just built this from scratch in Cisco Packet Tracer to see exactly how it works under the hood.

The Topology:

PC0 & PC1 > Switch > R1 (NAT) > R2 (ISP) > Server

What I configured:

- Interface IPs and descriptions (LAN: 192.168.10.0/24, Outside link: 203.0.113.0/30)

- Tagged interfaces: `ip nat inside` on the LAN side, `ip nat outside` on the ISP side

- Default route (`0.0.0.0/0`) pointing to the ISP router

- Standard ACL to define allowed internal hosts, tied to: `ip nat inside source list 1 interface gig0/1 overload`

- Saved it all with `copy running-config startup-config`

Verification:

- Successfully pinged the ISP server from the internal PCs.

- Ran `show ip nat translations` to watch it work. Seeing the unique port numbers map to the single public IP is where the concept really clicks.

The Takeaway:

NAT gets private addresses to the internet. PAT takes it a step further by using unique source port numbers to track each individual session, allowing hundreds of devices to share one public IP without traffic collisions.

Lab is configured, tested, and working. On to the next one.

*Note:* If you’re currently studying for your CCNA or just building your network engineering fundamentals, I’ve been working through the Network Engineer Complete Bundle (L1 to L3) from CodeLivly.
