Email Security 101: 5 Ways to Secure Your Email Address

Email security is a crucial aspect of modern digital life. Whether you’re an individual user or managing a business, ensuring that your email address is secure from threats such as hacking, phishing, and spam is essential.

Using online tools for checking suspicious links and protecting email accounts can greatly enhance your email security. Additionally, enabling two-factor authentication on personal accounts is highly recommended to protect sensitive data from unauthorized parties.

In this Mysterium VPN blog post, we’ll tell you about five essential methods to protect email accounts and keep sensitive data safe. By following these steps, users can significantly enhance their email security and reduce the risk of unauthorized access.

Create a Strong Password

Let's start with the basics: no email account is safe without a strong password. Here's what you should know about creating a strong password to protect your inbox.

A strong password is the first line of defense against unauthorized access to an email account. Weak passwords, featuring basic information like your mother's maiden name or your birthday, or passwords such as "password123" or "admin," are easily guessable and can be cracked by hackers within seconds.

A strong password should include a mix of upper and lowercase letters, numbers, and special characters. It should avoid easily guessable information such as names, birthdays, or dictionary words.

Creating a strong and unique password for each online account is crucial for security. Using the same password across different accounts is a significant security risk.

If one account is compromised, hackers can potentially gain access to all other accounts using the same password. Therefore, it is crucial to use uncommon passwords for each online account.

Hackers often use automated tools that try various combinations of common words and phrases to crack passwords. To create a strong password, avoid using dictionary words or common phrases. Instead, opt for random combinations of letters, numbers, and symbols.

Enable Two-Factor Authentication

Two-factor authentication (2FA), also known as two-step verification, adds an extra layer of security to an email account by requiring two forms of identification: something the user knows (password) and something the user has (a verification code sent to their phone).

Enabling 2FA on personal accounts can significantly reduce the risk of unauthorized access.

Most email providers, including Gmail and Apple Mail, offer the option to enable 2FA. This can typically be done through the account's security settings. Once enabled, users will need to enter a verification code sent to their phone whenever they log in from a new device.

An authenticator app, such as Google Authenticator or Authy, provides an extra layer of security by generating time-sensitive codes that are more secure than SMS codes. These apps can be used in conjunction with 2FA to enhance account security further.

Beware of Phishing Scams

Phishing scams are attempts by cybercriminals to trick users into revealing sensitive information, such as login credentials or credit card numbers, by posing as trustworthy entities.

Phishing emails often mimic legitimate emails from trusted sources but contain subtle signs of fraud. These can include suspicious links, spelling errors, urgent language, and requests for sensitive information.

Users should always be cautious and verify the authenticity of such emails before taking any action. Additionally, using online tools to check suspicious links can help prevent phishing and email fraud.

Common signs of phishing attempts include unexpected requests for sensitive data, offers that seem too good to be true, and emails containing malicious links or attachments. Users should always be wary of unsolicited emails asking for personal information.

Keep Software Updated

Keeping the operating system and email provider software up to date is crucial for security. Software updates often include patches for security vulnerabilities that hackers can exploit.

Users should ensure that they are using the latest versions of their email clients, such as Apple Mail or Outlook. Additionally, keeping antivirus software updated can help protect against malicious links and email attachments.

Enabling automatic updates for software can help ensure that users do not miss any important security patches. This small step can significantly enhance overall online security.

Use a Password Manager

Keeping up with your contact list can be difficult, not to mention keeping up with your passwords. We're here to help you!

A password manager is a valuable tool for managing and securing multiple accounts. It stores all unique passwords in one secure place, eliminating the need to remember them all.

Password managers generate and store strong passwords for each online account. They can also alert users if any of their passwords are weak or reused, thereby enhancing overall account security.

Popular password managers include LastPass, 1Password, and Dashlane. These tools provide a secure way to manage passwords and improve email security. Users should select a password manager that best suits their needs and start using it to protect their email and other online accounts.

Additionally, password managers can help create and store unique passwords for each account.

Well-Known Email Hacks, Their Consequences, and Lessons Learned

Email hacks have affected many high-profile individuals and organizations, leading to significant consequences. Here, we discuss some of the most notorious email hacks, their impacts, and the crucial lessons learned from each incident.

Yahoo Data Breaches (2013-2014)

Incident: Yahoo suffered two major data breaches, one in 2013 and another in 2014, affecting 3 billion and 500 million accounts, respectively.

Consequences:

• Personal information, including names, email addresses, telephone numbers, dates of birth, and hashed passwords, was stolen.
• Yahoo faced a significant loss of user trust and credibility.
• The breaches negatively impacted Yahoo's valuation during its acquisition by Verizon.

Bonus Tips for Email Security

• Monitoring for Unusual Activity: Regularly checking email accounts for any unusual activity is essential for maintaining security. If there are logins from unknown devices or locations, users should change their passwords immediately.
• Securing Email Servers: For those managing their own email servers, ensuring proper configuration and security is crucial. Using encryption protocols and regularly updating server software can help protect against unauthorized access.
• Avoid Sharing Passwords: Sharing passwords with others, even trusted individuals, isn't recommended. Maintaining password confidentiality is a fundamental security practice.
• Using Common Sense: Common sense is often the best tool for online security. If something feels off or too good to be true, it probably is. Trusting instincts and being cautious can prevent many security issues.
• Regularly Updating Security Settings: Periodically reviewing and updating email security settings to the latest version is vital. This includes changing passwords, updating security questions, and reviewing recovery options.
• Being Wary of Public Wi-Fi: Accessing email over public Wi-Fi networks can be risky due to potential security vulnerabilities. If using public Wi-Fi is necessary, a VPN should be used to encrypt the connection.
• Enabling Notifications for Suspicious Activity: Some email providers offer notifications for suspicious activity. Enabling these notifications can help users stay informed about potential security threats.
• Backing Up Data: Regularly backing up important emails and contacts ensures that data can be recovered quickly in the event of a security breach.
• Avoid Clicking on Suspicious Links: Before clicking on links, users should hover over them to check their destination. Suspicious or unfamiliar links should be avoided to prevent potential security risks.
• Using MFA for Other Accounts: Extending the security of two-factor authentication to other online accounts adds an additional layer of protection, making it harder for hackers to gain access.
