10 Mac-Hardening Security Techniques
Here are some foolproof, secure Mac security tips that you can implement to safeguard your data.
1. Enable the Mac’s built-in Firewall
One of the simplest ways to harden your Mac’s security is by enabling the built-in firewall. It can block unauthorized access to your PC by monitoring the incoming network connections. To enable the firewall, follow these simple steps.
  1. Go to System Preferences
  2. From there, enter ‘Security & Privacy’
  3. Click on the Firewall
  4. You will see a lock icon. Tap on it and then select ‘Turn On Firewall’
2. Keep Your Software Up-to-Date
It is essential to keep your software up-to-date to maintain the security of your PC. The updates contain security patches that address system vulnerabilities. To check for system updates, go to the Apple menu, click on ‘System Preferences’, and then ‘Software Update’.
3. Use a Strong Password
The simplest way to protect your data on your PC is by using a strong password. Make sure that your password is at least 12 characters long. It should include a mix of lowercase and uppercase letters, symbols, and numbers. Avoid using information that can be guessed easily, such as your birthdate, name, common words, etc.
4. Use Two-Factor Authentication
Two-factor authentication adds another layer of security to your laptop. It requires you to enter a code in addition to your password. This code is sent either to your phone or some other trusted device. To turn two-factor authentication on, simply go to the Apple menu and enter ‘System Preferences’. From there, go to Apple ID and ‘Password & Security’.
5. Use FileVault
FileVault is a built-in feature of MacOS. It allows you to safely encrypt your hard drive. Encrypting your hard drive makes it hard for unauthorized users to access your files even if they get their hands on your laptop. You can enable FileVault by going to ‘Security & Privacy’ and turning FileVault on.

6. Disable Auto Login
Even though it may save you some time while logging in, enabling auto-login reduces the security of your laptop. Disable this function so that it becomes hard for unauthorized people to get access to your files. You can disable auto-login in the ‘System & Preferences’. Go to ‘Users & Groups’, then ‘Login Options’. From there, you can turn the automatic login off.
7. Be Careful While Downloading Software
When you download apps online, you need to be careful. Malware can be disguised as legitimate software. Make sure that you download from sources that you trust. If you are downloading from a website for the first time, check its reviews and ratings first.
8. Use a VPN
Use a VPN to protect your online privacy and secure your internet connection. A VPN encrypts your traffic. It routes the traffic through a secure server. This makes it difficult for hackers to intercept your data. There are various VPN services available that you can use, both paid and free.
9. Use Anti-Virus Software
Antivirus software keeps your PC safe from cyber threats. There are many options available, like Norton, McAfee, and Avast. Choose an antivirus that is reputable and regularly updated.
