Cybersecurity — facts worth knowing.
The first computer virus that spread in the wild was the Elk Cloner, written by a 15-year-old in 1982 for Apple II systems. It spread via floppy disk and displayed a poem on every 50th boot.
Did you know?
The SolarWinds attack (2020) compromised 18,000 organizations including the Pentagon, Treasury, and Homeland Security by hiding malicious code inside a software update – demonstrating that supply chain attacks are the most devastating threat vector.
Did you know?
A major financial institution reportedly prevented a $1 billion heist attempt in 2016 when hackers who had already transferred $81 million from the Bangladesh Bank central account made a spelling error that triggered a manual review.

Why Cybersecurity matters.
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks through threat modeling, secure architecture, vulnerability assessment, and incident response. It requires both technical depth and adversarial thinking. Lemma sessions evaluate your ability to think like an attacker and design like a defender.
The cybersecurity workforce shortage is projected to reach 3.5 million unfilled jobs by 2025. Verified security expertise commands the highest premiums in tech. And unlike most skills, security knowledge that is not genuine creates real organizational risk – making peer verification especially valuable.

Cybersecurity verification — common questions
Peer sessions involve threat modeling, security architecture review, or vulnerability analysis. Your partner evaluates your understanding of attack vectors, defense strategies, and security-first design thinking.
Your Cybersecurity SCI measures competence in threat modeling, secure architecture design, vulnerability assessment, incident response planning, and security operations thinking.
Cybersecurity sessions can focus on either discipline. Your evidence trail shows whether you demonstrated offensive testing skills, defensive architecture, or both. The SCI reflects your demonstrated breadth.
Common topics include OWASP Top 10 vulnerabilities, threat modeling with STRIDE or PASTA, authentication and authorization design, network security, secrets management, and incident response planning.
CISSP and CEH are exam-based certifications that test knowledge breadth. Lemma verification captures your security reasoning and practical skills through live peer sessions with recorded evidence of your approach.
