New Book Summary: A Hacker's Mind by Bruce Schneier


My latest summary is for A Hacker’s Mind: How the Powerful Bend Society’s Rules, and How to Bend them Back by security expert Bruce Schneier. It's an interesting look at the systems around us through the lens of hacking.

As usual, the key takeaways are below, and you can find the full summary by clicking the link above.

KEY TAKEAWAYS

  • ​A hack is an activity allowed by the system that subverts the goal or intent of the system. Hacks exploit a vulnerability in the system to advance the hacker’s goal, rather than the system designer’s.
  • The main ways we can deal with hacks are:
    • Prevention. We can try to limit hacks by using principles of secure systems design.
    • Patching. Once a vulnerability is discovered, we can patch it to stop the hack.
    • Normalisation. Sometimes hacks get integrated into a system’s rules and becomes the new normal.
  • All sorts of systems—including market, legal, political, and cognitive systems—have vulnerabilities that can be hacked. Hackers can also target vulnerabilities at different levels of a system to achieve their goals.
  • Hacks can be a source of innovation. A system can evolve and become more resilient through hacking and patching.
  • However, hacks also have downsides:
    • Hacks are parasitical. A hack that is too successful can end up destroying the system it exploits.
    • Hacks tend to benefit the rich and powerful, who have more resources to find and normalise hacks.
    • Artificial intelligence will hack us at an unprecedented speed, scale, scope and level of sophistication. Our systems will need to become more flexible to respond.

Hope you're doing well. This month I posted 2 summaries and 2 blog posts. Book summaries The Art of Learning by Joshua Waitzkin (24 mins) — Waitzkin won 8 National Championships in Chess and later became a world champion in Tai Chi Push Hands.

This summary of The Book of Why: The New Science of Cause and Effect by Judea Pearl and Dana McKenzie explains how causal models can help us to better understand and control the world around us. This was a difficult one and I'm not sure how intelligible the key takeaways alone will be, as the diagrams are crucial to this book. Nevertheless, as usual I've set them out below and you can find the full summary (with diagrams) by clicking the link above. KEY TAKEAWAYS Statisticians woefully...
