When I started my career in cybersecurity 30 years ago, the digital world was vastly different. The internet was still in its infancy—back then, it was a luxury to hear the delightful sound of a dial-up modem connecting (if no one picked up the phone and ruined it). Mobile devices? Only in sci-fi movies. And cybersecurity? Let’s say it was considered as necessary as locking your front door in a neighborhood of polite neighbors. Concepts like ransomware and Zero Trust? They didn’t exist yet—probably because I’m older than Google, and these terms hadn’t been invented.

Over the decades, I’ve witnessed the field evolve dramatically, shaped by the rise of transformative technologies, the growing sophistication of cyber threats, and the ever-expanding reliance on digital infrastructure. From fighting worms like ILoveYou and Code Red to addressing the widespread panic of global incidents like WannaCry and SolarWinds, my journey has been marked by challenges, breakthroughs, and more caffeine-laden soda than I care to admit.
The industry’s growth has been nothing short of remarkable. As threats became more sophisticated, the tools to combat them grew in complexity and capability. Today, artificial intelligence plays a significant role in cybersecurity, from predictive analytics and automated threat detection to adaptive systems designed to outpace human attackers.
Whether you’re a seasoned professional or just beginning your journey, I hope these reflections will inspire, inform, and remind you of our critical role in securing the digital world. Let’s dive in.
The Early Days of Cybersecurity
The Landscape in the 1990s
In the 1990s, cybersecurity was a fledgling concept. The internet wasn’t the behemoth we know today—it was a fragile network that most people didn’t trust with their credit card information. Businesses operated in relatively isolated environments with minimal interconnectivity. Security was primarily physical: locked server rooms, limited system access, and maybe a sticky note with a password on the monitor (you know, for “convenience”). Firewalls and antivirus software were about as high-tech as it got.
Hackers back then were often seen as harmless pranksters, breaking into systems to display clever messages or embarrass their targets. Breaches rarely made headlines, and cybersecurity professionals were left waving their hands like overzealous car salespeople, trying to convince businesses to pay attention to a problem they couldn’t see yet.
Early Challenges
Convincing organizations of the need for security was like trying to sell flood insurance in a desert. Without high-profile breaches making headlines, cybersecurity was viewed as an unnecessary expense. Executives often said, “Why fix what isn’t broken?”—famous last words they’d later learn.
Tools and resources were limited. Intrusion detection systems were in their infancy, and automation wasn’t a thing yet. We primarily relied on manual processes, late-night brainstorming sessions, and an unhealthy amount of caffeine. It was the Wild West, and we were trying to shut the bank vault.
The Rise of Early Worms, Viruses, and DDoS Attacks
The early 2000s marked a turning point. Suddenly, the internet wasn’t just a novelty but a playground for worms, viruses, and distributed denial-of-service (DDoS) attacks. These weren’t just technical challenges—they were endurance tests. Some of the most memorable battles from this period include:
- Stacheldraht (Barbewire) DDoS Tool (1999–2000s): Named after the German word for “barbed wire,” this sophisticated tool introduced encrypted communication between attackers and compromised systems. It mobilized botnets for large-scale DDoS attacks, forcing teams like mine at Dell Computers to work late into the night to restore services. It felt like playing whack-a-mole, but it was a network of infected machines instead of moles.
- ILoveYou Worm (2000): This worm spread via email attachments with the subject line “ILoveYou.” It infected millions of computers globally within hours, leaving devastation (and awkward conversations) in its wake. Educating users about suspicious attachments became a priority. I still chuckle, thinking about one user who claimed, “But the email said it loved me!”
- Code Red Worm (2001): Targeting Microsoft IIS servers, Code Red was a fast-moving worm that exploited vulnerabilities and defaced websites. Containing it was a race against time. I vividly remember the weekend spent patching systems at Dell Computers, fueled by vending machine snacks and sodas.
Each incident was a learning experience, not just in technical terms but in working under pressure and solving problems as a team. The hours were long, and the stakes were high, but those moments forged the foundation of modern cybersecurity practices.

Those early days of cybersecurity laid the groundwork for today’s robust defense strategies. Late nights, weekends, and countless cups of coffee and sodas shaped the industry and the professionals who fought tirelessly to defend it.
As I reflect on these formative years, it’s clear how far the cybersecurity industry has come and how important it is to stay vigilant as threats evolve. If you’ve been in the trenches of cybersecurity, take a moment to appreciate how much the field has progressed—and how much we’ve all aged along the way!
