Every internet-connected device needs adequate protection from all evil online forces. Of course, there is no singular option to keeping your Mac secure. 

In the end, it is a strategic combination of measures, taken to lower the chances of becoming infected or compromised. So, let’s jump into the techniques for maintaining a secure environment in your Mac.

Why do you need to protect your Mac?

Securing information is a compulsory exercise undertaken by all governmental and commercial agencies to prevent hackers from gaining access to critical data. Hackers successfully break into networks and devices of organizations that fail to secure them by implementing robust data security policies and programs. 

Poor network security policy, weak passwords, unattended computers, and inefficient information management practices lead to data loss or theft. 

Hackers on the prowl are constantly looking for weak targets like unsecured networks and devices to break into. These vulnerabilities and threats can be countered using encryption software, Virtual Private Network, and creating a robust user and data management policy. 

However, even these might not offer sufficient protection against advanced hacking attempts on your Mac device. 

According to Malwarebytes, attacks against Mac devices continue to increase, meaning that you need to take action as soon as possible. In essence, it is you, the user, who has the resources and authority to stave off hacking attempts. Here’s a list of some smart tips to secure your Mac device from hackers. 

Perform software updates

It’s important to carry out regular system updates, especially if you connect your Mac device to the internet. Go to the System Preferences option from Open the Software Update tab. 

You must enable the “Check for Updates” option, and don’t forget to set the same for “Daily.” You can also choose the command line option: it’s called the Software Update. Go through the primary page for further details.   

Recently, Apple released a patch for macOS Catalina 10.15.7. Its primary focus is to fix several exploitable bugs that could be used to hijack devices. 

Some of the vulnerabilities had the potential to allow hackers to run malicious scripts in users’ computers. One relied on FontParser, giving crooks a chance to turn fonts into components of an attack. Hence, it is crucial that you update as soon as possible anytime a new patch arrives. 

Use a non-admin account 

It might be useful to create a separate account for all your mundane activities. The administrator account has the privileges to make modifications and install programs. You do not need these rights to browse the web. 

Whenever you feel like making changes, you can simply type in the correct credentials when prompted. While it might seem inconvenient, it actually could make your Mac safer. If you notice some random messages requiring the admin account, it might serve as a clue that your device is infected. 

Check account settings

You must disable the option for Automatic Login. You will need to open the Accounts tab under the System Preferences to accomplish this goal.  Now, click on the Login Options and specify the Automatic Login option to “Off.” Additionally, you must also set the Display login window as” to “Name and password.”

Sharing and Guest Account can also be disabled by selecting the Guest Account and unchecking the “Allow Guest to log in to this computer” option. Additionally, you should also uncheck the “Allow guests to connect to shared folders” so that no one can access the shared folder by simply logging in to your Mac device. 

Backup your data

Backing up important data is essential for any user. For instance, Time Machine is a built-in feature that can let you automatically preserve data in an external storage device. Before you start using, you need to assign an external storage device as a safe location for your information. 

It can be a USB or a Thunderbolt drive. You can set the Time Machine to make backups in various intervals (like hourly or daily). 

Configuring firewalls

Mac systems include two firewalls: the new Application Firewall and the IPFW Packet-Filtering Firewall. These firewalls determine the programs that have permission to receive all incoming connections. Configuring the firewall is easy; however, IPFW Firewall configurations are complex and need some level of technical expertise. 

Installing a VPN

A VPN on Mac guarantees a secure connection between your Mac device and the internet, which is not always welcoming to users. The secure channel created carries encrypted data, which is nearly impossible to decipher. 

Thus, the end-to-end encryption offered by a VPN can prevent data loss and theft by making a secure communication tunnel. After installing a reliable and reputed VPN, you can connect to the internet without worrying about accidental data leaks or monitoring.  

The above smart tips can save your information from falling into the hands of unauthorized people or hackers. Without following these tips, you expose yourself to an array of threats and misfortunes. 

So, do not hesitate to dig deeper into your Mac. After that, you can improve other aspects of your digital life, such as using two-factor authentication or opting for more private browsers.
