An insightful question about AI and LLM security 🤔

𝗤: So, how could organizations defend themselves against AI injections? Or is it more about the developers of LLMs, not the users?

𝗔: Great question — and it’s both, really 🙂

➡️ LLM providers (Devs) need to harden their models against prompt injection by improving context handling, sandboxing actions, and applying prompt input filters.

➡️ But orgs using LLMs also have responsibilities:

→ Avoid blindly integrating AI into sensitive workflows (Do the security check first!)
→ Sanitize and validate user inputs before sending them to the model.
→ Log and audit AI activity — treat it like any critical system.

I see both misconfigurations and poor input handling open the door to attackers. Don’t let your guard down.

My Path Into Cybersecurity Started With a Choice That Changed Everything.

I was top of my Computer Science class at Military Institute of Telecommunications and Information Technologies (MITIT) with multiple career paths ahead of me.

Then, I heard about a brand-new cybersecurity unit being formed in 2015.

Most classmates chose traditional tech roles. Military Intelligence looked prestigious. Telecommunications seemed stable.

But something about defending critical infrastructure from invisible enemies sparked something in me I didn't know existed.

Picture this: 2015, Ukraine. Cyber warfare wasn't theoretical — it was happening in real-time.

I walked into that newly formed cybersecurity unit as a fresh graduate with book knowledge.

I walked out every day knowing I was part of something bigger than code and algorithms.

We weren't just IT professionals. We were digital defenders.🛡

Working in AFU's cybersecurity division taught me lessons no classroom ever could:
→ Stakes are real - When defending critical infrastructure, there's no "test environment."
→ Teamwork saves lives - Cyber defense isn't solo when national security is on the line.
→ Adaptability is survival - Threat actors don't follow textbooks.
→ Purpose fuels performance - Protecting your country changes how you approach problems.

My MITIT teacher who saw potential in cybersecurity before it was mainstream.
My AFU manager, who believed in developing talent, not just using it.
These people showed me what it means to serve something bigger than yourself.

Starting in that unit in 2015, I never imagined I'd grow into SOC Division Chief.

Here's what I learned:
1. Technical skills get you in the door
2. Leadership skills keep critical systems protected
3. People skills turn individual defenders into unified teams
4. Strategic thinking transforms reactive responses into proactive defense

It's not about being the smartest person in the room. It's about caring deeply enough to never stop learning, defending, and improving.

Was it:
A personal experience?
A mentor who opened your eyes?
A realization about how much depends on digital security?
A desire to serve and protect?

After 2 weeks of #CyberMonday threat intel and CVE updates, I want to hear from YOU.

Every Monday, I share the latest threats, key CVEs, and Cybersecurity news to help you stay ahead.

My goal? Make your week safer and save you hours of research. But I know every team has different needs.

Here’s what I want to know:
→ Are these weekly updates helping you spot risks faster?
→ Do you use them to brief your team, patch systems, or guide your strategy?
→ What would make these updates even more useful for you?

Your feedback shapes what I share next. I want #CyberMonday to be your go-to for:

1️⃣ Actionable Threat Intel
2️⃣ Fast CVE Highlights
3️⃣ Simple, clear takeaways you can use right away

Help me deliver the best #Cybersecurity content for YOU 🙂

I rarely ask for help, but today I must. 30,000 UAH could save real lives.

As a military and cybersecurity professional, my work is usually about building defense, in the cloud and on the ground. Today, I am reaching out for something even more personal.

The 3rd Assault Brigade (3 OShBr 🇺🇦) is in need of our help.

→ The goal is: 30,000 UAH.
→ The need is urgent: funds will support ‘Павук Допхіна’ ('Dolphin Spider'), a new multi-purpose platform built by the Brigade’s own engineers.
→ The impact is real: stronger tech means more lives protected and more missions completed.

Supporting these engineers is not just about equipment. It is about empowering the kind of innovation that keeps people safe and gives us a real edge.
