Cyber security is extremely important, especially in the times we live in. I did study a bit of Internet and information security back at university about 12 years ago, as a part of my Computer Science degree, but most of that knowledge is outdated probably. So, to be sure, recently I took a couple of courses on Udemy, that really opened my eyes and made me a better teacher, because now I can teach my students about the most modern cyber threats and ways to secure your life, sensitive info and data. While doing these cyber security courses I mentioned, I stumbled upon many quotes by famous people in these fields. I’ll share 15 of them with you now, and I hope they inspire you as much as they inspired me.

- “The only truly secure system is one that is powered off, cast in a block of concrete, and sealed in a lead-lined room with armed guards.” – Gene Spafford, a renowned computer scientist and cybersecurity expert known for his work in software engineering and computer security
- “Privacy is dead, and social media holds the smoking gun.” – Pete Cashmore, the founder and CEO of a digital media website, known for his insights into the intersection of technology and society
- “In cybersecurity, the more systems we secure, the more we encourage hackers to outsmart us.” – Dan Kaminsky, a cybersecurity researcher and chief scientist, known for his work in computer security, cryptography, and DNS (Domain Name System)
- “Companies spend millions of dollars on firewalls, encryption, and secure access devices, and its money wasted; none of these measures address the weakest link in the security chain.” – Kevin Mitnick, “The most famous hacker in the world”
- “The only thing that can stop a bad guy with a computer is a good guy with a computer.” – Mark Burnett, a cybersecurity expert and author known for his work in password security and network protection
- “Hackers are now breaking the systems for profit. Before, it was about intellectual curiosity and pursuit of knowledge and thrill.” – Kevin Mitnick, as mentioned earlier, known for his insights into the evolving landscape of cybersecurity threats and motivations.
- “If you spend more on coffee than on IT security, you will be hacked. What’s more, you deserve to be hacked.” – Richard Clarke, a former national security official and cybersecurity expert, known for his insights into the importance of investing in cybersecurity measures
- “Security is not a product, but a process.” – Bruce Schneier, a prominent security technologist, author, and cryptographer, known for his expertise in cryptography and security protocols
- “There are two types of companies: those that have been hacked, and those who don’t know they have been hacked.” – John Chambers, former CEO of Cisco Systems, highlighting the prevalence of cyber attacks and the importance of cybersecurity preparedness for organizations
- “Cybersecurity is a race between the good guys and the bad guys, and we’re all in the race together.” – Michael Dell, CEO of Dell Technologies, highlighting the ongoing battle between cyber defenders and attackers
- “The weakest link in the security chain is the human element.” – Kevin Mitnick, reinforcing the importance of cybersecurity awareness and education among individuals to mitigate risks.
- “Every time you type a password into a computer, you’re relying on the security of someone else’s code.” – Avi Rubin, a computer scientist and cybersecurity expert, reminding users of the inherent trust placed in software systems and the importance of rigorous security testing
- “The best way to secure your system is to assume it’s going to be breached.” – Bruce Schneier, advocating for a proactive approach to cybersecurity that anticipates and mitigates potential breaches rather than relying solely on prevention
- “Cybersecurity is not just about protecting your devices and data, it’s about protecting your way of life.” – Barack Obama, former President of the United States, highlighting the broader implications of cybersecurity for individuals, societies, and economies
- “The most dangerous phrase in the language of cybersecurity is ‘we’ve always done it this way.'” – Grace Hopper, a pioneering computer scientist and naval officer, emphasizing the importance of adaptability and innovation in cybersecurity strategies

If you like those quotes, you can download them as a PDF I created. I used those wise words and turned them into posters that you can print and use in some of the following ways:
- Displaying on empty walls that need a bit of decor
- Classroom bulletin boards
- Offices / Staff lounges / Free time areas around the school
- Printed as cards and gifted to students or friends
This is the FREEBIE PDF file, feel free to download it from the link below 😊
I would love it if you snapped a picture of this freebie in use and sent it to me 😊 – hanging on some wall at your school/classroom/computer lab, or as part of a great bulletin board you or your students created 😊
