Apple's Big Bet to Eliminate the iPhone's Most Targeted Vulnerabilities Alongside new iPhones, Apple released a new security architecture on Tuesday: Memory Integrity Enforcement aims to eliminate the most frequently exploited class of iOS bugs. Apple launched a slate of new iPhones on Tuesday loaded with the company's new A19 and A19 Pro chips. Along with an ultra-thin iPhone Air and other redesigns, the new phones come with a less flashy upgrade that could turn out to be the true killer feature. A security improvement called "Memory Integrity Enforcement" combines always-on chip-level protections with software defenses in an effort to harden iPhones against the most common--and commonly exploited--software vulnerabilities. In recent years, a movement has been steadily growing across the global tech industry to address a ubiquitous and insidious type of bugs known as memory-safety vulnerabilities.
