Study Notes

### Thinking Like a Hacker to Defend

“If you know the enemy and you know yourself, you need not fear the results of a hundred battles.” - Paraphrased from Sun Tzu’s famous quote
Cybersecurity is asymmetric warfare.
“Defenders think in lists. Attackers think in graphs. As long as this is true, attackers win.” - John LaTour and others
The weakest link in the chain of cybersecurity is humans.

### Cybersecurity Governance, Risk, and Compliance

Mitigate to reasonableness and accept residual risk.
There are three key defenses for cybersecurity: Defence-in-Depth, Defence-in-Breadth & Defence-in-Diversity
Defence-in-Depth is a solution across people, process, and technology
Defence-in-Breadth means including two layers of firewalls,
Defence-in-Diversity means using a diverse product and service portfolio.

### Cybersecurity Incident Response and Crisis Management

Paying ransoms does not guarantee the restoration of data or the return of stolen data.
Paying ransoms encourages future attacks against the victim company and others, it can also run afoul of the US sanctions regime.
There are legal and reputational risks associated with paying ransoms.

### Cybersecurity at the Cutting Edge

Zero Trust is a cybersecurity framework that assumes no user or device can be trusted by default.
Threat intelligence analysis and sharing involves collecting and analyzing data to identify potential threats and vulnerabilities.
The use of Threat Intelligence and Zero Trust strategies is key to staying ahead of attackers.

Future for Cybersecurity

There is an increasing need for greater collaboration and information sharing between organizations.
AI and Automation are going to play a larger role in cybersecurity, but they will be accompanied by new and unique risks that need to be managed.
Cybersecurity is now an arms race.
