In an enlightening discussion with The Independent, Ivan Krstić, Apple’s head of security engineering and architecture, has shed light on the company’s relentless efforts in fortifying iPhone security and the Cupertino firm’s stance on sideloading and third-party app stores.

Amid the European Union’s looming regulatory changes, Krstić emphasized the potential risks associated with allowing iPhone users to install apps from sources other than Apple’s App Store.

Krstić argued against the notion that most iPhone users would continue using the App Store even in the event of sideloading being permitted. He stated that the reality of alternative distribution could force users to rely on third-party sources for essential apps, compromising their ability to choose a trusted platform. “That’s a great misunderstanding – and one we have tried to explain over and over,” Krstić said, highlighting the risk of users being compelled to abandon the App Store’s secure ecosystem.

This perspective aligns with Apple executive Craig Federighi’s previous comments, in which he labeled sideloading as a “cybercriminal’s best friend”. Despite this strong stance, Federighi has acknowledged the possibility of Apple having to comply with the EU’s sideloading regulations.

Krstić also touched upon Apple’s broader security practices and the company’s often contentious relationship with government agencies regarding user data protection. He explained: “We do not see ourselves as set against governments… but we do see ourselves as having a duty to defend our users from threats, whether common or in some cases, truly grave.”

The report offers a comprehensive look into Apple’s security measures, the debate surrounding iPhone app distribution, and the company’s commitment to safeguarding user data against external threats.
