34 Network Security In addition to user account and system security, network security is also very important to organizations. The OS X firewall protects your <strong>Mac</strong> from unauthorized incoming access from other systems on both a local network and the Internet. The virtual private networking (VPN) service provides a secure method for your computer to remotely access networks. OS X Firewall The OS X personal firewall can be used to block unwanted incoming connections to your computer. A firewall protects the services on your computer from other computers on the network or Internet. Services that are turned on in Sharing preferences already appear in the list of services to which other computers can connect. To prevent incoming connections to one of these services, you must turn off the service in Sharing preferences. Enable the OS X firewall: 1. Choose <strong>Apple</strong> menu > System Preferences, click Security & Privacy, and then click Firewall. 2. Click the lock icon to unlock it, and then type an administrator name and password.
3. Click Start to enable the firewall. Configure advanced firewall options: 1. While in the Firewall pane of Security & Privacy preferences, click Advanced. 2. You can choose from three advanced firewall options: Select the “Block all incoming connections” checkbox to allow incoming connections for basic Internet functions only. You’ll still be able to check email and browse the web but this mode will prevent all sharing services found in the Sharing pane of System Preferences, such as File Sharing and Screen Sharing, from receiving incoming connections. To use these services, deselect this option. 35
