A small mainframe will do. Hackers stole “only” 4.5 million patient records.
Or better yet, I assume, they need to use a mainframe the federal government already has. Based on a quick search, I’m quite sure the U.S. federal government has DB2 for z/OS available.
People have had problems getting their U.S. passports and visas processed for 3 weeks and counting. Three weeks!
Why do eBay’s employees (plural!) have access to all of eBay’s master customer databases? DB2 for z/OS offers strict security separation (e.g. SECADM, DBADM, and other, highly selective authorities). eBay (and Paypal) should be using a real mainframe database with real security to protect its customers and its business reputation.
Choose the right tool for the job, eBay.
