Securing a Mac

We recommend the following best practices for securing you Mac.

Install the latest Mac OS patches and security updates

Apple releases patch and security updates regularly. New vulnerabilities are often the target of attackers. We recommend that you apply Apple patches and security updates as soon as they are released. When critical security updates are released we will notify all MCS users; for less important updates we will notify individuals subscribed to the mac-users e-mail list.

Disabling services/Enabling the Mac firewall

When on potentially hostile networks you should disable all unnecesary services and enable the Mac OS firewall. The MCS network, or your home network if it sits behind a NAT, would not be considered hostile. Starbucks or any other public WiFi is generally considered hostile.

From the "Sharing" System Preference, disable all unneeded services.

In the "Security and Privacy" Preference Pane,

  1. In the FileVault tab, turn FileVault on
  2. In the Firewall tab turn the Firewall on
  3. In the Firewall Options button, block all incoming connections (top checkbox).

If you need to share, only enable the necessary services or ports while you are actively using them.

Consider AntiVirus software

To protect your Mac from e-mail viruses you should not open attachments unless you know the sender, were expecting that attachment, and you know what it is. If you receive an unexpected attachment from someone you know, you should confirm that they intended on sending it before opening it.

For extra security, you can also install Avast Antivirus, available on the Mac Software page. It will detect and neutralize infected e-mails and disk images.

Argonne also provides McAfee antivirus for lab-managed machines. Contact to get it installed on your machine.
