Security News > 2021 > February > Apple details major security, privacy enhancements in its devices

The company has released on Thursday a newer version of its Platform Security Guide, outlining the security and privacy innovations and improvements its users will be able to take advantage of.

The M1 chip is supposed to speed up Macs and improve their performance, but according to the updated Platform Security Guide, there are new security protections built deep into M1's code execution architecture.

For Macs with Apple silicon, the control of the LocalPolicy file, which describes the configuration that the user has chosen for the system boot and runtime security policies, has been transferred to an application running in the Secure Enclave - to prevent malware from downgrading security policy controls in order to gain more privileges.

Finally, different security policies on a Mac with Apple silicon can be set for each installed operating system, and malware won't be able to downgrade a security setting to make the system easier to compromise.

For details about more security and privacy improvements, check out the document revision history of the Guide.

Apple has also set up a new Security Certifications and Compliance Center, and has provided more info about the Apple Security Research Device - special iPhones provided to researchers to probe the security of the OS..
