[9] In August 2024, one of the largest data security breaches was revealed.
Investment in cybersecurity, denoted as z, reduces v based on the effectiveness of the security measures, known as the security breach probability function. Gordon and Loeb demonstrated that the optimal level of security investment, z*, does not exceed 37% of the expected loss from a breach. Specifically, z* (v) ≤ (1/e) vL.
On August 27, 2024, The Washington Post reported that at least 2 major internet service providers in the United States had been compromised by Chinese hackers. [1] It was later reported that the hackers affected at least nine telecommunications firms in the U.S., including AT&T, Verizon, Lumen Technologies, and T-Mobile, and had also affected dozens of other countries.
