It is no secret that Mac computers are well-known for their high-end security, sleek design, and lightning-fast performance. Despite Apple’s best efforts to ensure macOS is impenetrable, it isn’t completely immune to vulnerabilities. Therefore, it is critical for users to understand the common threats and employ proactive measures to safeguard their Mac computers and ensure a stress-free user experience.
Let’s look at the common vulnerabilities and their mitigation strategies.
Malware and Viruses
Malware and viruses can infect your system through various means, including infected websites, downloads, and phishing emails. The common signs of virus infection are:
- The web browser’s homepage changes without your knowledge
- New extensions appearing on your browser
- You are receiving excessive ads and pop-ups
- You are receiving security alerts and notifications intimating your system is at risk
- You are unable to access private files
To mitigate this infection and ensure your entire system isn’t infected, you can try these steps:
- Scan Mac for virus by checking the Activity Monitor for any troublesome process or app. You can also uninstall all the suspicious-looking extensions and apps or clear downloads. If you don’t prefer manual scanning, you can install a reputed antivirus program and run automatic scans.
- Whenever you are downloading email attachments/files or opening emails, you must be cautious. If you don’t know the sender, verify the sender is genuine.
- Before you connect external drives, ensure they are scanned.
- Ensure you back up your Mac computer so your data stays protected in the event of a virus infection. This will help you to format your computer and reinstall macOS without a second thought.
- Make sure your operating system and all the applications are updated regularly. Updates generally come with the latest security patches to identify the latest threats and thwart their attempts to steal your data or harm you in any way.
Phishing Attempts
Phishing attempts are more common than you think, even if you are using a Mac. These are socially engineered attacks that are aimed at tricking users into revealing confidential information or installing malware. Phishing attackers impersonate legitimate contacts or websites. Hence, staying alert is critical.
You can mitigate phishing attacks by:
- Verifying the links and email senders before clicking
- Hovering over the links to reveal the true URLs
- Use unique and strong passwords for your accounts, and ensure the passwords are different for all your accounts. You can use a password manager to keep track of these different passwords.
- Enabling two-factor authentication so that even if someone hacks your password, they will be unable to access your account without the one-time secret code.
- Installing anti-phishing tools to prevent such attacks.
Outdated Software
One of the biggest red flags is outdated software. If it has been a while since you have updated your macOS software and the apps on your computer, you are dealing with hidden vulnerabilities. These vulnerabilities can be easily exploited by cyber attackers.
This can be mitigated in the following ways:
- You can enable automatic macOS updates so that whenever your computer is idle, the update will run in the background.
- You can also turn on automatic updates for your applications.
- Ensure that you regularly check whether everything is updated and in order. If not, manually update them.
- If there are unused, redundant apps, remove them. This decreases the chances of attacks.
Using Weak Passwords
It is a cardinal sin to use weak passwords that can be easily hacked by anyone, including hackers. Also, you must not use the same password for all your accounts, especially the ones containing sensitive information.
You can mitigate this by:
- Creating unique and strong passwords for each account. Use a password manager to create and manage your passwords.
- Avoiding the use of personal information in passwords as they can be easily hacked. Also, avoid using simple passwords, such as QWERTY12 or 1234567890.
- Enabling two-factor authentication for an added layer of protection.
Vulnerable Wi-Fi Network
If you are using public Wi-Fi networks, be wary. These networks are usually vulnerable to man-in-the-middle attacks and eavesdropping. To ensure your data is not being stolen when you are connected to a public Wi-Fi network, keep these in mind:
- Always check whether you are connecting to the right network. Ask the concerned person before clicking Connect.
- Use a VPN to encrypt your traffic so your sensitive data is protected and snoopers are kept at bay.
- Do not access confidential information when connected to an unsecured Wi-Fi network.
Addition Tips to Stay Safe
- Create regular backups of your data so it is easily recoverable.
- Educate and update yourself on the latest threats.
- Follow Apple’s news to learn of the latest security updates and how you can use them for your benefit.
In summation, security is not a one-off thing. It is an ongoing process. You must understand and educate yourself of the vulnerabilities to always stay a step ahead.
