Businesses, especially SMEs, must know that [phishing](/dmarc-fundamentals/understanding-phishing-and-other-cyber-threats/) emails are the **primary modus operandi** for cybercriminals to introduce malware into information network systems. Therefore, email security gains significance for businesses to protect themselves from **malicious threats**. # **What is Email Security?** _Email security is a comprehensive term representing various methods, tools, strategies, policies, and approaches for protecting email communication, accounts, and associated information of organizations and individuals from **unauthorized access**._ Email security involves safeguarding any information transmitted via email to prevent intruders from accessing it. Besides, it includes anti-spam measures, like **authentication tokens**, to legitimize email messages and ensure they originate from a trusted source. In addition, it **monitors email traffic** to detect suspicious activity and offers virus and malware protection as additional security measures. ![Email Security ](https://media.mailhop.org/dmarcreport/images/2023/04/dmarc-analyzer-1687.jpg) ## **Why is Email Security Critical for Businesses?** Besides helping businesses defend their overall **cybersecurity posture**, email security is critical because, · It protects business networks from malicious [cyberattacks](https://www.bbc.com/news/uk-england-gloucestershire-64917275). · It ensures **data privacy** by protecting customer data. · It ensures the confidentiality of email conversations. · It prevents the leakage of **sensitive data**. · It ensures proper regulatory compliance. ## **What Risks do Unsecured Emails Pose?** Emails present the **most convenient channel** for malicious actors to launch cyberattacks and gain access to sensitive information. If your information systems do not have adequate email security measures in place, it is a clear invitation for **unauthorized persons** to intercept and read your email messages. As a result, it could lead to data privacy issues and pose significant threats like [identity theft](https://web.archive.org/web/20250512213747/https://edu.gcfglobal.org/en/thenow/what-is-identity-theft/1/), financial fraud, and data breaches. Malicious actors use the following **attack vectors** to exploit email security vulnerabilities and access your information network. - **Phishing** Phishing is the most **widespread** cyberattack vector that uses emails and other communication channels to glean sensitive information, like user credentials, credit card details, and other confidential data. The malicious actor sends an **innocuous-looking email** seemingly originating from a genuine and trusted source, such as a bank or a supplier, to deceive the recipient into divulging personal confidential information. Usually, phishing attacks are **successful** because they prey on user [vulnerabilities](https://www.balbix.com/insights/what-is-a-vulnerability/) like greed, fear, and a sense of urgency by including email subject lines that warrant **immediate action**. For example, it could say, “Your email account has been suspended,” or “You have won a million-dollar lottery.” It can even threaten the recipient by stating, “Immediate Action Required.” - **Spear Phishing** Spear Phishing is an **advanced mode of phishing** where the malicious actor uses emails to target specific individuals or organizations. Like regular phishing emails, **spear phishing** emails seem to originate from a genuine, trusted source. However, these emails can contain [malicious attachments](https://www.clearnetwork.com/malicious-attachments/) or spurious links, coercing the targets to download or click on them to introduce **malicious code**, allowing the cyber attacker to access the victim’s information network system. - **Spoofing** An **unsecured email system** is a sitting duck for [spoofing attacks](https://www.malwarebytes.com/spoofing). Here, cybercriminals send emails from fictitious but seemingly-genuine sender addresses, creating the impression that the emails have originated from a legitimate source. It enables malicious actors to access sensitive data and launch **malicious code** and malware into the system. Spoofing allows these criminals to commit identity theft and use their credentials to perpetrate financial fraud. - **Business Email Compromise** Business Email Compromise (BEC), also known as **whaling**, targets high-level personnel within the organization. Cyber attackers use **social engineering** tactics as a pre-planned interactive process to build rapport and convince their targets to open malicious links and emails, compromising confidential information. Since these emails appear to originate from a reputable source, like the [CEO](https://www.dallasnews.com/business/entrepreneurs/2023/03/27/how-a-southlake-tech-ceos-high-flying-lifestyle-imploded/) or other top officials, they leave little scope for the victims to suspect their genuineness. ## **How to Ensure Email Security?** ![Email Security](https://media.mailhop.org/dmarcreport/images/2023/04/dmarc-analyzer-1688.jpg) We have seen the vulnerabilities of an **unsecured email system**. Therefore, securing your emails is critical to strengthening your organization’s cybersecurity posture. These best practices help secure email accounts, allowing businesses to carry on with their core activities **comfortably**. - **Password Security** A typical robust password comprises at least eight characters, involving a combination of upper and lower case alphabets, numbers, and special characters. For additional security, it can also contain invisible characters, which can be created using online platforms like [Editpad](https://www.editpad.org/tool/invisible-character). One should not use **easy-to-guess passwords**, like spouse or child’s name, date of birth, anniversary dates, etc. Similarly, using the same passwords for all your accounts, including social media or personal blog accounts, is not advisable. - **Email Encryption** Encrypting emails ensures that the messages are not tampered with in transit. Encryption means scrambling the messages into an **unreadable format** that only authorized users can decipher. Thus, it becomes challenging for malicious actors to hijack these emails and read and alter their contents. Hence, encrypting emails can **protect the business** from potential data breaches. - **Using Multi-factor Authentication** Multi-factor authentication involves adding an **extra security layer** to a user’s email account. It secures the email account because the user must go through two or more authentication steps before accessing it. Besides the password, [multi-factor authentication](https://www.onelogin.com/learn/what-is-mfa) can be through an OTP (one-time password) or a code sent to the user’s **registered phone number**, a biometric scan, or any other means of unique identification. Businesses require multi-factor authentication to **protect confidential and sensitive data**, including customer, employee, or stakeholder information. Unsecured email systems without proper multi-factor authentication and authorization allow malicious actors to access data and **compromise information** assets. - **Implementing Email Authentication Standards** Organizations can utilize **email authentication standards** including Sender Policy Framework ([SPF](/dmarc-fundamentals/what-is-spf/)), along with Domain Keys Identified Mail ([DKIM](/blog/dkim-explained-how-dkim-works-and-why-is-dkim-important-for-organizations/)) and **Domain-based** Message Authentication Reporting and Conformance ([DMARC](/)) to secure their email systems and mitigate email threats. Learning [how DMARC alignment works](/blog/what-is-dmarc-alignment-and-how-does-it-work/) helps ensure these protocols actually validate your mail. A [DMARC checker](/tools/dmarc-checker/) lets you verify these records are set up correctly. ## **Conclusion** With cybercriminals employing innovative tactics to launch cyberattacks, organizations must include email security as an **integral component** of their organizational cybersecurity framework. It helps protect their confidential data from being **breached**. Therefore, business entities should stipulate adequate measures, like implementing stringent authentication procedures, using proper encryption protocols, and deploying effective [anti-malware](https://www.xcitium.com/blog/malware/what-is-antimalware/) and robust **endpoint security** solutions to ensure comprehensive email security. For ongoing visibility into your domain, consider [DMARC monitoring plans](/pricing/) that track authentication continuously. ## Topics [ dkim ](/tags/dkim/)[ dkim selector ](/tags/dkim-selector/)[ dmarc record ](/tags/dmarc-record/)[ dmarc record policy ](/tags/dmarc-record-policy/)[ email security ](/tags/email-security/) ![Brad Slavin](https://media.mailhop.org/dmarcreport/images/team/brad-slavin.jpg) [ Brad Slavin ](/authors/brad-slavin/) General Manager Founder and General Manager of DuoCircle.
