In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and untrusted external network, such as the Internet. Firewalls are often categorized as either network firewalls or host-based firewalls. The Symantec Endpoint Protection firewall for Mac does not integrate with the operating system's built-in firewall. Instead, it runs in parallel. The operating system firewall inspects at the Application layer, while the Symantec Endpoint Protection firewall inspects at lower levels (Network and Transport). Most Mac users will be adequately protected by the built-in firewall. If you want or need extra protection, Little Snitch is an excellent starting point. If you only need to shut out one or two apps, Radio Silence will get that done most efficiently. Where can we find the firewall log files for ENS for MAC for troubleshooting firewall issues? Policy to log blocked/allowed event seems to be applied to windows only. Is there no firewall log file available for MAC Like we have locally on Windows VSE (McAfeeFireLog.txt)? If not how can we troubleshoot firewall blocking issues? Firewalls monitor and regulate the data moving on and off your computer or network. They can keep criminals out while allowing legitimate network traffic in. Mac OS X comes with not one but two.
Firewall settings let you customize how firewall should monitor and respond to the inbound and the outbound network communications. Firewall settings contain the access settings for the applications, services, and ports on your Mac. They also contain access settings for connections to or from the other computers in the network to which your Mac is connected.
You can use the Firewall window to customize the following firewall settings:
Application Blocking | Lets you configure firewall rules for the applications that run on your Mac to connect to the Internet. The Application Blocking settings determine whether to allow or deny an application, such as a web browser or iTunes, from connecting to the Internet. Application Blocking settings are not specific to a particular network location. The Application Blocking settings do not change when you change to a different network location. You can use the Configure option under Application Blocking to set Internet access for applications on your Mac. Whenever an overlap exists in the settings between Connection Blocking and Application Blocking, the Connection Blocking settings take precedence over the Application Blocking settings. |
Background for mac. Connection Blocking | Lets you allow or block the applications, ports, services, and IP addresses that:
The Connection Blocking settings determine whether to allow or deny the incoming or the outgoing connections that use a specific service, application, or a port. You can also configure firewall to allow or block a specific IP address on the network. Connection blocking settings apply only to a particular location. https://zqhmry.weebly.com/music-programs-for-mac.html. You can use the settings icon in the Connection Blocking row to set connections for applications and services on your Mac. |
Vulnerability Protection | Helps you in detecting and preventing Intrusions through the Internet. Vulnerability Protection monitors all the incoming and the outgoing traffic on your Mac and blocks any unauthorized access. It provides information about the susceptibility of the programs that may be on your Mac against malicious attacks. It also provides information about the known attacks. You can manage the list of signatures for Vulnerability Protection. |
Location Awareness | Lets you configure the firewall settings based on the network location to which your Mac is connected. The firewall settings that you configure contain the connection blocking settings for the application and services that run on your Mac. When you connect your portable Mac to a new network location, your Norton product prompts you to select a new firewall setting for the network location. |
DeepSight | Lets you access and configure the Norton DeepSight Community Download. This feature lets you obtain the updated list of IP addresses that Symantec identifies as attackers. You can enable the Norton DeepSight Community Download feature to obtain the updated list of IP addresses from Symantec servers. |
Firewall is software that’s there to protect you so it’s best to keep it turned on. With Firewall running, your Mac takes care of everything — automatically determining whether or not an application is allowed to send or receive traffic from the network. It does this using Code Signing Certificates that are issued to trusted applications. Without the proper certification, an app isn’t allowed through. Think of it like a bouncer on the door of a club — if an app doesn’t have the proper ID it ain’t coming in.

Say, for example, you’re playing a video game and don’t want to access the online multiplayer modes. Or antivirus software that you’ve installed is conflicting with Mac’s Firewall application.
Turning off Firewall solves these problems. But you should be aware that, while switching off Firewall can stop apps on your computer from sending traffic to the network, it provides free reign for incoming connections, leaving you vulnerable to malware and hackers.
Clean your Mac before changing settings
Before we show you how to turn Firewall on and off, it’s recommended that you have a cleanup of apps on your system, particularly those that you’ve previously deleted. If you’ve ever downloaded an app by mistake and uninstalled it or found an app to be malicious and sent it to the Trash, there’s every chance that their remnants still exist on your system.
Firewalls For Mac Computers
If that’s the case and you have Firewall switched off, these apps will be able to send and receive traffic, putting your Mac at serious risk.
So, if you plan on playing around with the Firewall settings, use a tool like CleanMyMac X to find and remove any unwanted files that exist on your system. CleanMyMac scans all of your disks and compiles installed apps. It also identifies broken and outdated apps so that you can easily remove them.
Here’s how to use it:
- Download and launch CleanMyMac X. (Free download)
- Click on the Uninstaller tab.
- Click on View All Applications and select any apps that you wish to remove from the list. Apps can be sorted by Name, Size, Selection, and Last Launch Date to help your search.
- Click on Complete Uninstallation from the dropdown menu.
- Click on the Uninstall button and enter your admin password when prompted.
Selected apps will now be completely removed from your system.
Okay, with that out of the way, let’s get into enabling and disabling Firewall.
How to turn on Firewall on Mac
Mac’s Firewall settings can be found in the Security and Privacy preference in System Preferences.
To enable Firewall in macOS and OS X v10.6 or later:

- Click on the Firewall tab.
- Click on the lock icon in the bottom left corner of the window and enter your administrator password.
- Click Start.
How to disable Firewall for Mac
Turning off the Firewall is simply a case of following the same instructions as above and clicking on the Turn Off Firewall button.
To do this, you may need to enter your administrator password.
Firewall advanced settings
By clicking on the Firewall Options button (or Advanced for OS X) you’ll find additional settings that give you more control over how the Firewall performs.
In the list, you’ll see all of the apps that are currently allowed to send and receive network traffic. By clicking on the application to highlight it and hitting the '-' button, you can remove an app from the list. Alternatively, clicking on the '+' button lets you add a new app to the list.

You’ll also be presented with three options:
- Block all incoming connections — this blocks all connections other than those required for basic internet services.
- Automatically allow signed software to receive incoming connections — this automatically allows software signed with a valid certificate to gain access to the network for sending and receiving traffic.
- Enable stealth mode — this prevents Mac from responding to probing requests.

The great thing about Firewall for Mac is that it takes care of everything for you, regulating the access of apps to the network to keep your system safe from malicious activity. As said, it’s best to keep Firewall turned on and let it does its thing. But if you do plan on turning it off, even just for a short time, run CleanMyMac X prior to doing so to rid your Mac of old apps lurking in the depths of your system.
