In the connected world we live in today, securing your Mac is one of the most important steps. Though Macs have strong security features, nothing is impervious to threats. Cyber-attacks, malware, and privacy breaches are the harsh reality, and you have to give touch to your Mac to prevent all such issues. To help keep you safe when using your Mac, here are some best practices to keep in mind.
How to Install Antivirus Software for Your Mac
And one of the best ways to do that is to use antivirus software on your Mac. Although macOS comes with security measures, these are far from always perfect, particularly when new threats pop up. This provides you more security against malware, spyware, and ransomware attacks, which is why installing a reputable antivirus Mac program is highly recommended. Most antivirus software today incorporates features such as malware scanning in real-time, web protection, and email filtering that can identify and stop threats from causing harm.
Enable macOS Firewall
Your Mac, however, has a built-in firewall — you just need to make sure it’s on. Firewalls are security devices that create a barrier between your device and external networks. By activating the macOS firewall, you are preventing access on your Mac from unrecognized apps and services.
Keep macOS and Apps Updated
Software updates include essential security patches that fix vulnerabilities in the operating system or apps. Perhaps the easiest but most effective thing you can do to secure your Mac is to keep macOS, and all installed apps up to date. Outdated software is a common target for cybercriminals, so regular updates are essential in helping to mitigate the risk of a compromise.
Use Strong Passwords & Enable Two-Factor Authentication(2FA)
Passwords are your first line of defense against unauthorized access to your Mac, so always make them strong and unique. A secure password features a combination of upper and lower-case letters, numbers, and symbols. Do not use passwords that are easy to guess, like “password123″ or your name. Use a password manager that can securely store and generate strong passwords for your many accounts.
Besides utilizing strong passwords, enable Two-Factor Authentication (2FA) for extra protection. Two-factor authentication (2FA) adds an extra layer of security by requiring another form of verifiable credential — a code that is sent to your phone or email, for instance — besides your password. This makes it a lot harder for hackers to break in, even if they have your password.
Be Wary of Phishing Attempts
Phishing is probably the most common way for criminals to steal your personal information. Phishing emails or text messages might look like they come from trusted entities (like your bank, online services, or even coworkers), but they contain links or attachments that can steal your data.
Take care when following links or downloading attachments, especially from unknown sources. Check the sender’s email address and if ever in doubt, go straight to the official website (for example, the IRS for U.S. taxpayers) to see if there are any alerts or updates.
Encrypt Your Hard Drive
By encrypting your Mac’s hard drive, you ensure that all of your data are safe and sound, in case of losing the device or your Mac is stolen. Your Mac comes with a built-in encryption tool which is known as FileVault, and works by automatically encrypting your full hard drive with relief from any silly ciphers.
To enable FileVault, visit System Preferences > Security & Privacy > FileVault and follow the prompts to enable it. Be sure to store your recovery key in a safe place, as you will need it if you ever need to recover your account.
Remember to Restrict App Access and Avoid Public Wi-Fi
Apps have access to many freedoms on your Mac, including your camera, microphone, and location. This reduces the risk of an app taking advantage of these permissions, so regularly review the permissions you have assigned to each app and only limit what you need.
Also, make sure to only connect to secured Wi-Fi networks and do not use public Wi-Fi to do sensitive business, such as logging into your bank or shopping. Use a VPN when needed to encrypt your internet traffic and keep your privacy intact.
By taking these precautions—installing antivirus software, turning on the firewall feature, installing updates to your system, using strong passwords, carefully evaluating phishing, encrypting your hard drive, and using secure Wi-Fi—you can help ensure that your life online is safe. However, a properly protected Mac will ensure you avoid potential threats and have a safer online experience. Be more vigilant, and your Mac will be more secure.
