Best quote from Harvard CS50: The Cybersecurity Roadmap with David Malan
Cybersecurity is not an absolute state; it is a function of risk and reward. If you make it difficult and expensive enough for an attacker to get into your accounts, they will likely lose interest and move on to an easier target.

Frequently Asked Questions
The course, led by David Malan, emphasizes that while an individual must be perfect in their defense, an adversary only needs to be right once. It shifts the focus from total prevention to a model of detection and auditing. By understanding that cybersecurity is a function of risk and reward, you can learn to raise the bar for attackers, making it too difficult or expensive for them to compromise your digital perimeter.
This roadmap is designed for everyone, regardless of whether they consider themselves a 'computer person' or not. It provides a comprehensive guide to securing data, accounts, and privacy in a digital age. By teaching the first principles of how computers work, the course empowers users to deduce how to handle both current and future cyber threats that the world has not yet encountered.
David Malan explains that securing your digital life is like protecting a house; leaving even one small window ajar can compromise the entire perimeter. The course focuses on practical risk management by making it harder for attackers to gain access. It also highlights the importance of minimizing downsides through effective auditing, ensuring that if a breach does occur, it is detected quickly to protect your sensitive information.
