What Is The Squid Game All About?

The Squid Game's rules mirror classic childhood games turned deadly. The perimeter drawn in sand represents a squid's outline, with defenders patrolling the boundaries and attackers attempting to breach them while hopping on one leg. Once past the defenders, attackers can use both legs to reach the “squid head” and win—but one wrong move means elimination (or death, in the show's context).

This high-stakes game serves as a perfect metaphor for cybersecurity:

Defenders = Your security systems and IT team
Attackers = Cybercriminals probing for weaknesses
Squid Perimeter = Your network's digital boundaries

Cybersecurity Lessons From Squid Game

Lesson	Description	Real-World Application
Don't Trust Easily (Red Light, Green Light)	The unsuspecting players are eliminated for trusting the deceptive doll's instructions.	Be cautious of online interactions and information. Verify sources, avoid clicking suspicious links, and be wary of overly generous offers.
Information Asymmetry (Honeycomb Game)	Players with prior knowledge of the game (shapes) have a significant advantage.	Attackers often exploit vulnerabilities in software or human error. Stay updated on cybersecurity threats and best practices.
Strength in Numbers (Tug-of-War)	The stronger team (more members) wins, highlighting the importance of teamwork.	Utilize multi-factor authentication and implement security measures across your entire network (personal or business).
Physical vs. Digital Security (Glass Bridge Game)	The “tempered” glass bridge represents strong security, while the “normal” glass is a security weakness.	Implement strong passwords data encryption, and regularly update software to patch vulnerabilities.
Desperation Breeds Risk (Marbles Game)	Players take extreme risks due to desperation in the game.	Financial desperation can make people more susceptible to phishing scams or malware. Be cautious of online financial opportunities, especially those promising quick and easy returns.
Beware of Internal Threats (The Hostage Situation)	The game's mastermind is revealed as one of the participants.	Insider threats can be just as dangerous as external threats. Implement access controls and be mindful of who has access to sensitive information.

Case Study: The Red Light, Green Light Phishing Lesson

In 2022, Google reported blocking 100 million phishing emails daily. Just like players who moved during “Red Light” were eliminated, employees who click malicious links often compromise entire networks. A 2023 IBM study found that 95% of cybersecurity breaches result from human error—proving why verification is crucial.

What Does The Squid Game TV Series Have In Common With Cybersecurity?

Modern organizations face attacks from multiple vectors—cloud, mobile, IoT devices—just as Squid Game contestants faced unexpected challenges. Here's the cybersecurity parallel:

The Squid Perimeter = Your network's firewall and endpoint security
Defenders = Your SOC (Security Operations Center) team and tools like SIEM systems
Attackers = Advanced Persistent Threats (APTs) or ransomware gangs

Cybersecurity Tips From Squid Game Series To Help You Up Your Game: SEASON 1

1. Build Your Defenses Like The Squid Perimeter

Actionable Steps:

Conduct a data audit to identify critical assets (customer data, IP, financial records)
Deploy next-gen firewalls with intrusion prevention (Palo Alto, Fortinet)
Use endpoint detection and response (EDR) tools like CrowdStrike
Budget at least 10-15% of IT spending on security (Gartner recommendation)

3. Defense-in-Depth: The Glass Bridge Strategy

Like the tempered vs. normal glass in the show, layered security ensures attackers face multiple barriers:

Layer	Security Measure	Example Tools
Perimeter	Firewalls, Email Filters	Cisco Firepower, Proofpoint
Network	IDS/IPS, Network Segmentation	Darktrace, Splunk
Endpoint	Antivirus, EDR	SentinelOne, Microsoft Defender
Data	Encryption, DLP	VeraCrypt, Symantec DLP

CHECK OUT: GlassWire Network Firewall

4. Prepare For Unknown Threats (The VIPs' Game)

The show's unpredictable VIPs mirror advanced persistent threats (APTs). 34% of breaches in 2023 involved novel attack vectors (Source: Mandiant M-Trends).

Incident Response Plan Checklist:

Conduct quarterly tabletop exercises
Maintain an updated contact list for crisis response
Store offline backups (3-2-1 rule: 3 copies, 2 media types, 1 offsite)
Subscribe to threat intelligence feeds (Recorded Future, etc.)

Season 2 Cybersecurity Lessons: The Return of Deception 🎭

1. Advanced Social Engineering (The Recruitments)

In Season 2, returning or new participants are subtly manipulated into joining the deadly games, often through promises or emotional appeals. Just like in real life, attackers exploit trust to gain entry into systems.

Real-World Application:

Train employees regularly to spot phishing emails, fake calls, and pretexting attempts.
Simulate attacks through controlled phishing campaigns (tools like KnowBe4 or PhishMe).
Verify unusual requests for sensitive information, even if they appear to come from leadership.
Example: An employee receives a convincing “urgent invoice” email from finance. Without verification, clicking it could unleash malware — just as a contestant trusting the recruiter faces elimination.

2. Multi-Layered Monitoring (The Underground Games)

The hidden games in Season 2 feature multiple surveillance points, catching every subtle move, ensuring that mistakes don’t go unnoticed. In cybersecurity, single-layer defenses aren’t enough; threats can bypass one system and exploit another.

Real-World Application:

Continuous network monitoring using SIEM tools like Splunk or LogRhythm.
Behavioral analytics to detect unusual user activity or privilege misuse.
Redundant checks for critical systems: firewall + EDR + endpoint monitoring.
Example: Just like a contestant is watched by cameras in blind spots, attackers may lurk in systems unnoticed without comprehensive monitoring. Multiple layers make detection faster and containment more effective.

Season 3 Cybersecurity Lessons: Insider Threats Amplified 🕵️‍♂️

1. Exploiting Familiarity (The Insider Advantage)

Returning players leverage their prior knowledge to exploit vulnerabilities in new contestants. Similarly, insiders in organizations — whether employees, contractors, or partners — have knowledge that external attackers do not.

Real-World Application:

Role-Based Access Control (RBAC): Only allow access necessary for a user’s role.
Audit trails & logging: Track every action to identify suspicious behavior.
Periodic access reviews: Revoke privileges that are no longer needed.
Example: A former employee retains access to shared folders and exfiltrates data. Proactive monitoring and strict access controls prevent such exploitation.

2. Contingency Planning (The Extreme Twists)

Season 3 throws unexpected twists at players — sudden rule changes, hidden traps, and ambushes. Cybersecurity faces similar uncertainty with zero-day exploits, ransomware, and advanced persistent threats (APTs).

Real-World Application:

Incident response plan: Keep it updated, test it quarterly, and include clear communication protocols.
Redundant backups: Apply the 3-2-1 rule (3 copies, 2 media types, 1 offsite).
Rapid patch management: Ensure critical updates are applied within hours of release.
Example: A ransomware attack encrypts critical servers. Organizations with tested contingency plans restore systems quickly, just as contestants adapt to survive sudden game changes.

✅ Key Takeaways From Seasons 2 & 3:

Trust is currency: Never assume trust — verify everything (Zero Trust).
Knowledge is power: Insider awareness and monitoring prevent exploitation.
Layer your defenses: One line of defense is never enough.
Plan for surprises: Cyberattacks evolve; preparation reduces damage.

How can small businesses implement Squid Game-level security affordably?

Start with these low-cost measures:

Enable free MFA (Microsoft Authenticator, Google Authenticator)
Use built-in security tools (Windows Defender, macOS Gatekeeper)
Train staff with phishing simulation tools (KnowBe4 has free tiers)

How does the “information asymmetry” in the Honeycomb Game apply to real-world cybersecurity?

Just like players with shape knowledge had an advantage, cybercriminals exploit unpatched vulnerabilities. The CISA KEV Catalog shows 60% of breaches use vulnerabilities where patches existed but weren't applied. Always update systems within 72 hours of patch releases.

The Marbles Game shows desperation leading to bad decisions. How does this translate to cyber risks?

Financial stress makes people 3x more likely to fall for “get rich quick” scams (FBI Internet Crime Report 2023). During economic downturns, fake investment scams increase by 200%. Always verify opportunities through official channels before acting.

What's the cybersecurity equivalent of the Glass Bridge's “testing each step”?

This mirrors penetration testing:

Conduct annual red team exercises
Use automated vulnerability scanners weekly
Test backup restoration quarterly (40% of backups fail when needed)

How can teams collaborate securely like the Tug-of-War game winners?

Implement team-based security:

Shared password managers (Bitwarden, 1Password)
Role-based access controls (RBAC)
Security champion programs in each department

Microsoft found this approach reduces incidents by 58%.

The show features disguised threats. What's the cybersecurity parallel?

This represents fileless malware and living-off-the-land attacks:

31% of attacks now use legitimate tools like PowerShell
Deploy behavioral analysis tools (CrowdStrike, SentinelOne)
Monitor for unusual system tool usage patterns

How does the “elimination” concept apply to cybersecurity?

This mirrors automated threat containment:

Set SIEM rules to isolate compromised devices
Automatically revoke credentials after 3 failed logins
Quarantine suspicious emails with sandboxing

Gartner shows this reduces breach impact by 72%.
