Email Security

Email is essential. Everyone from the largest organizations to small businesses, and even individuals rely on email. From its origins in the 1970s, email did not come with security and privacy measures – and still does not have these features today. It is important to curtail the threats posed by this vector of attack, and Email Security is the solution.

Email Security refers to the process of detecting and eliminating threats and spam flooding into your inbox. That’s the high-level explanation.

Specifically, this can refer to a multitude of tools in this Toolbox, including domain spoofing, phishing attacks, potential malware and spam emails, and encrypting potentially harmful or unknown content.

Ever received an email from an external source? If the image it contains is blurred, that’s Email Security at work. Let’s peer into the process, and examine the Key Features of Email Security and the respective benefits they convey.

Features of
Email Security

Encryption

Refers to the practice of masking content in an email message to prevent it from being viewed or altered by unauthorized parties. The message content, images, and links are encoded, only to be decoded and viewed by the recipient’s email provider. There are two kinds, transport-layer encryption, and end-to-end encryption.

Emails, when sent, are not directly sent to the receiver as they are routed through mail servers. The journey from sender to recipient is longer than meets our eye. Anyone, including the email service provider, could interject and read this email if it is not encrypted.

Spam Filtering

Filters out Spam, also known as inappropriate or unwanted email messages. All email providers have some basic level of spam filters, but they aren’t able to fully eliminate spam emails. Spam, while not directly harmful like a Phishing Attack, can be used in combination with domain spoofing (impersonation) to send spam emails without being flagged as such.

Organizations can employ a third-party spam filter, in conjunction with the basic filtering provided by their email service provider, to limit the amount of spam an inbox receives. Known spam emails should also be marked as such; to train the filtering algorithms they already have in place.

Phishing Security

Protects email users from Phishing Attacks, which try to steal sensitive information from a victim. Once they have the information they need (usually in the form of login information or a password), they might either sell the information or compromise the account directly.

Email Security plays a part here by filtering emails from identified threat sources, removing embedded and untrusted links within message content, and equipping email users with the necessary soft skills to identify a phishing email.

Malware Protection

Protects email users from malicious programs that are delivered via email, particularly through email attachments. Malicious code can be disguised as innocuous attachments like a PDF or Word Document, that can be used to compromise an endpoint.

Email Security here blocks or prevents attachments from harming the user, such as scanning incoming emails with an anti-malware filter to identify potential threats.

Benefits of
Email Security

Implementing robust email security measures offers numerous advantages that protect both individuals and organizations:

Protection Against Cyber Threats

Email security safeguards against a wide range of cyber threats, including phishing scams, ransomware, and malware attacks. By preventing unauthorized access to your inbox, you can minimize the risk of data breaches and identity theft.

Enhanced Privacy

With encryption and secure protocols, your email communications remain confidential. This is especially crucial for businesses that handle sensitive client information or proprietary data.

Increased Trust and Credibility

When you prioritize email security, you build trust with your clients and partners. They can have confidence that their information is safe, enhancing your professional reputation.

Regulatory Compliance

Many industries are subject to stringent regulations regarding data protection. Implementing effective email security measures helps you meet compliance standards, avoiding potential fines and legal repercussions.

Cost Savings

By preventing breaches and associated recovery costs, robust email security can save businesses significant amounts of money. The cost of a data breach often far exceeds the investment in preventive measures.

Use Case of
Email Security

Now that we’re familiar with the Features of Email Security and the Benefits they provide to your cybersecurity posture, let’s visualize an example of how this would work in real-time.

Meet Emily, A Marketing Consultant

Emily runs a successful marketing consultancy and relies heavily on email for client communication. One day, she received an email that appeared to be from a well-known client, requesting urgent information. Without thinking, she clicked the link and provided her login credentials.

Before Email Security Implementation

This seemingly harmless action resulted in a significant security breach. Hackers accessed her email account, sending fraudulent emails to her clients, damaging her reputation, and jeopardizing client relationships.

After Implementing Email Security

Realizing the vulnerability of her email communications, Emily decided to implement a comprehensive email security solution. She installed encryption software, activated multi-factor authentication, and set up advanced spam filters. Additionally, she conducted training sessions for her team to recognize phishing attempts. The results were transformative. Emily’s email communications became significantly more secure. The encryption ensured that sensitive information was protected, while the spam filters effectively blocked phishing emails. With MFA in place, even if someone attempted to compromise her password, they would face an additional barrier.

The Outcome

As a result of her proactive approach to email security, Emily regained her clients' trust and avoided further security incidents. Her consultancy thrived, and she became an advocate for best practices in email security within her industry.
