Tolkien Reading Day, celebrated every March 25th, honors J.R.R. Tolkien’s life and timeless works. His epic stories not only captivate us but also offer unique parallels to modern challenges, including the evolving landscape of cybersecurity.
For example, Frodo and Sam evade Orc patrols using disguises and unexpected routes to reach Mount Doom. This is much like how hackers use obfuscation techniques and zero-day exploits to bypass security undetected. Similarly, Beren and Lúthien employ disguises and magic to infiltrate Morgoth’s fortress, paralleling tactics hackers use, like social engineering or spear-phishing, to breach systems. Lúthien’s enchantments disable Morgoth’s guards, reflecting exploits that bypass antivirus systems. Finally, Erebor’s hidden door serves as a metaphor for cybersecurity backdoors, which attackers exploit to enter systems unnoticed.
These stories draw valuable cybersecurity lessons from Tolkien’s tales, offering insights to inspire stronger practices and cyber hygiene. Here’s a closer look at three key examples:
-
The Hidden City of Gondolin – Reducing the Attack Surface
“You can fence yourselves in, but you cannot forever fence it out”
During the First Age, the elven city of Gondolin was concealed in a hidden valley with secrecy and barriers as its main defenses. Its location remained a closely guarded secret, and its fortifications were designed to repel most attacks. Despite this strength, the city fell when an insider, Maeglin, betrayed it. Morgoth’s forces exploited this betrayal and discovered vulnerabilities that led to its downfall.
Cybersecurity Lesson: Even strong systems face failure without regular updates and improved measures. Insider threats, in particular, bypass external barriers and exploit trust, making them very dangerous.
Reducing the attack surface is essential for minimizing risks and staying proactive against threats. To achieve this, you can:
- Implement Zero Trust principles, such as least privilege policies, strong access management, and network segmentation. This ensures only authorized users can access specific information.
- Conduct regular vulnerability assessments and penetration testing to identify and address weaknesses before they are exploited.
- Regularly update and patch systems to close potential entry points for attackers.
Continually improving these defenses strengthens resilience, helping address both external and internal risks.

The Beacons of Gondor – Detect and Respond to Cyber Threats
“It is a long road, and there are many dangers; but you are not without allies.”
The beacons of Gondor were signal fires on mountaintops that served as an early warning system. This network communicated danger quickly over long distances. Using this system, Gondor alerted and mobilized allies in critical situations, like during the War of the Ring.
Cybersecurity Lesson: Early detection and fast responses are critical for security. Like Gondor’s beacons, proactive tools can detect threats, signal warnings, and facilitate quick reactions.
Building an efficient detection and response strategy involves:
- Deploying robust monitoring systems to act as your beacons. These systems track network activity in real time to identify potential threats early.
- Using AI and machine learning for anomaly detection and automated responses. These technologies rapidly analyze data to highlight unusual patterns and enable swift action.
- Establishing clear incident escalation protocols to ensure rapid collaboration between teams.
Preparation, vigilance and teamwork are key. These approaches help mitigate risks and protect assets.

The Scouring of the Shire – Recovering from a Cyberattack
“Hold on to your hope. The world is not yet beyond repair.”
At the end of the War of the Ring, the Hobbits returned to find the Shire devastated by outside forces led by Saruman. Frodo, Sam, Merry and Pippin rallied the Hobbits, who took back their home and rebuilt. They focused on restoration and applying lessons learned during their long journeys.
Cybersecurity Lesson – Recovery after a breach matters greatly. Resilient organizations minimize damage and recover swiftly. Like the Hobbits, identifying the issues and working as a team enables action.
Here are the key steps for recovery:
- Contain the attack to limit damage. Isolating affected devices ensures the rest of the network stays protected.
- Restore from backups to maintain data integrity. Immutable backups allow a return to a clean state without further corruption or threats.
- Conduct a post-attack evaluation to address vulnerabilities. Learning from incidents creates stronger systems.
Recovery relies on teamwork and coordinated efforts. Together, your organization can rebuild its network stronger than before, like the reclaimed Shire.
Closing Thoughts
Collaboration and ongoing improvement are critical to building strong cybersecurity. Just as the Fellowship united diverse skills to succeed, effective security requires trust and cooperation. Partner with experts, promote a culture of awareness, and maintain vigilance. Whether in Middle-earth or a modern workspace, preparation and resilience remain your best defenses.
