Apple iOS and macOS are prone to multiple security vulnerabilities. Attackers can exploit these issues to gain sensitive information or execute arbitrary code. This may aid in further attacks.
Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.
Restrict local access to trusted and accountable individuals only.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from a successful exploit.
Implement multiple redundant layers of security.
As an added precaution, deploy memory-protection schemes (such as nonexecutable stack/heap configuration and randomly mapped memory segments). This may complicate exploits of memory-corruption vulnerabilities.
Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, run applications with the minimal amount of privileges required for functionality.
Updates are available. Please see the references or vendor advisory for more information.
