Existing security mechanisms are designed to keep hackers out. However, they have unavoidable vulnerabilities - chiefly due to human weaknesses (e.g., phishing attacks). We cannot prevent these break-ins, but we can minimize their impact by making critical data tamper-proof by using blockchain technologies. Conventional blockchain systems, however, are difficult to use because of the requirement for new programming languages, tools, and workflow processes. This is changing as blockchain features are being incorporated into general-purpose databases. This makes it possible to implement blockchain in mainstream applications with minimal effort. This talk will begin by introducing the threats posed by hackers and compromised insiders. Then we will describe an implementation of in-database blockchain and how it can protect your data against these threats. We will compare this against conventional blockchains as well as share use cases from customers who have adopted this technology.
