Apple devices although highly secure are constantly targetted due to their popularity.

We recommend the following actions be taken:

  • Apply appropriate patches/updates provided by Apple to vulnerable systems immediately after appropriate testing.

  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.

  • Reminder to all staff not to download, accept, or execute files from un-trusted or unknown sources.

  • Remind to all staff not to visit untrusted websites or follow links provided by unknown or un-trusted sources.

  • Cyberkite can also assist in applying the "Principle of Least Privilege" to all systems and services to reduce chances of malicious viruses to run amuck.
