Description: The ‘Hardened Runtime’ is a security feature implemented in various operating systems aimed at protecting applications from potential malicious attacks. This functionality restricts the capabilities of applications, limiting their access to system resources and preventing them from performing unauthorized actions. By hardening the runtime environment, the goal is to minimize the attack surface, meaning that even if an application is compromised, its ability to cause harm is significantly reduced. This feature is particularly relevant in a context where cyber threats are becoming increasingly sophisticated. The ‘Hardened Runtime’ integrates with other security measures, such as application integrity verification systems, which validate the integrity of applications before allowing them to run. Together, these tools provide a robust framework to protect both individual users and organizations, ensuring that applications behave safely and predictably.
History: The ‘Hardened Runtime’ was introduced by Apple in 2018 as part of macOS Mojave (version 10.14). This feature emerged in response to an increase in security threats and attacks targeting applications. Aiming to strengthen the security of the operating system, it was implemented to provide greater protection for users and developers. Since its launch, it has evolved with periodic updates that have improved its effectiveness and expanded its capabilities.
Uses: The ‘Hardened Runtime’ is primarily used in applications that require a high level of security, such as those handling sensitive data or operating in corporate environments. Developers can enable this feature when compiling their applications, allowing them to benefit from additional security restrictions. This is particularly useful for applications distributed through official app marketplaces, where compliance with stricter security standards is expected.
Examples: An example of the use of ‘Hardened Runtime’ can be seen in security and privacy applications, such as antivirus or encryption tools, which need to protect user information from unauthorized access. Another case is that of enterprise applications handling confidential data, where the implementation of this feature helps mitigate security risks.
