Despite the fact that there is an enormous variety of new kinds of messengers now, e-mail remains one of the most popular and convenient forms of communication. We send and receive communication letters via email every day. Among the numerous emails, there are frequently crucial and secret documents. However, the convenience of e-mail comes with numerous risks. Security risks. Cyberattacks become increasingly common. Due to this the risks of transmitting sensitive information via email increase. 

This issue affects businesses, government entities, and individuals. After all, the loss of confidential data has serious consequences. So below, we will explore the key email security risks associated with using email to transfer confidential files.

Key Takeaways

  1. Email remains a widely used communication tool, but it poses significant security risks when transmitting confidential information.
  2. Common threats include data interception, phishing attacks, and malware, all of which can compromise sensitive information.
  3. Utilizing encryption, two-factor authentication, and secure email services are essential to enhance email security.
  4. User education and training play a crucial role in recognizing and avoiding security threats, especially phishing attempts.
  5. Implementing Data Loss Prevention solutions can help monitor and restrict the unauthorized transmission of sensitive data.

Main Threats of Sending Confidential Information Via Email

  • Email often does not provide a sufficient level of encryption. Most users use standard email services. The latter do not guarantee complete security when sending messages. Thus, hackers can intercept and even modify the content of emails. 
  • Users rarely think that the files they send via email may remain on the servers of service providers without proper protection. This raises the risk of unauthorized access to these files. Especially in the event of a service provider error or a server-side cyberattack.
  • There is a major issue with phishing. Hackers construct bogus emails to lure people into disclosing sensitive information. If consumers are unaware of how to protect themselves, they run a high danger of falling victim to a phishing assault.

In addition to the risks associated with transferring files via email, you should not forget about threats to mobile devices. Do iPhones get hacked? The answer is yes. This question is of great concern because even the most sophisticated security systems can have vulnerabilities. 

If confidential information is transmitted via an unsecured email on a hacked device, the risk of data leakage increases significantly. Although iOS smartphones are known for their high security, the threat remains real. In particular, iPhone hacked signs include sudden changes in battery life and strange application behavior. Also, unexpected notifications about unknown activity on the device. The specialized resource also provides other important tips.

Is It Safe to Send Confidential Information Via Email?

When you send confidential information via email you may pose several risks, making it generally unsafe without proper precautions. All critical risks can be found in the subsections below.

Types of Risks Associated with Sending Sensitive Information Via Email 

Data Interception, Phishing Attacks, Incorrect Addressing, Malware and other things are the ones that may cause huge problems if you don’t pay much attention to security methods and strategies.

Phishing Attacks

This is one of the most dangerous types of attacks. During these attacks, attackers send fake emails that are hard to distinguish from official ones. Therefore, users often trust them. By entering confidential information on a fake website, hackers steal data and use it for criminal purposes. This is one of the most common types of email security risks in the world.

Data Interception

While most modern email services use encryption, some of them still leave room for attacks. If users send emails over open Wi-Fi networks or don’t use the HTTPS protocol, hackers can intercept this data. In this case, email data breach risks increase significantly. In financial services—especially for those working with clients with bad credit—the secure handling of sensitive client data is essential. Unauthorized access or phishing attempts targeting this information can lead to severe consequences for both the provider and the client.

Incorrect Addressing

The human factor is also one of the reasons you should pay attention to. These are cases when users mistakenly send confidential files to the wrong addresses. This is also part of email risks.

Malware

When a user opens an infected file or link, malware can attack their computer. This puts the entire system at risk.

In addition to the risks mentioned above, it is also worth paying attention to the company’s security and data management policies regarding the processing of confidential documents. After all, employees often become the biggest threat to data protection without realizing it. 

The lack of instructions and protocols

The lack of mandatory instructions and clear protocols for processing and transferring confidential information often leads to potential data leaks. 

Unprotected devices

The use of unprotected devices, such as personal smartphones or computers without antivirus protection, also increases the risk of hacking.

Using email hosting services without proper security measures can also leave your email vulnerable, especially if these devices are compromised.

Inattention to the physical security of devices

If a smartphone or computer is lost or stolen, and the user has not properly protected their email accounts, attackers can gain access to important data in the vast majority of cases. 

Using the same passwords for different accounts

This makes hacking one account the key to many others.

Social engineering

These are methods by which hackers manipulate people to gain access to their accounts or information. They can use psychological pressure and persuasion to get the information they need. 

How to Send Sensitive Information Via Email?

If you want to send sensitive information via email without being attacked by hackers and other fraudsters, you should apply various approaches which we will describe below. Please, pay attention to them.

Enable Two-factor Authentication

Using two-factor authentication can greatly lower the danger of email breaches. Even if a hacker has access to the password, they will have a more difficult time accessing the account without the subsequent level of verification.

Deploy Email Authentication

Email authentication protocols like SPF, DKIM, DMARC, and MTA-STS can play a huge role in ensuring sensitive company information doesn’t get leaked. 

Enable Email Encryption

Many modern email services offer support for encrypting messages using technology. In particular, Pretty Good Privacy (PGP). Encryption ensures that only the sender and the recipient can read the contents of the message.

Use Secure Email Services

There are services that specialize in enhanced security. They offer end-to-end encryption and other security features that reduce email risks.

Prioritize User Training

Raising users’ awareness of email security risks will increase success in reducing phishing attacks and other threats. In particular, organizations should train their employees to recognize suspicious emails, always verify the correct recipients before sending messages, and never open unknown files or links.

Also, companies must develop not only technical but also behavioral methods of protection.

Adopt Data Loss Prevention Solutions (DLP)

Implementing Data Loss Prevention technologies can dramatically boost email security. DLP tools assist in:

  • monitoring, 
  • detecting, 
  • preventing the unauthorized movement of sensitive data outside a company. 

These technologies can automatically detect emails containing confidential data or sensitive information. Thus, preventing them from being transmitted without proper authority. By integrating DLP with email systems, businesses may do the following:

  • regulate the flow of sensitive data,
  • reduce the risks associated with inadvertent or purposeful data breaches.

Summary

Sending confidential files via email is a common practice. But it is far from safe. Various email security risks put both personal and corporate data at risk. However, the use of modern encryption technologies and increased user awareness can help significantly reduce these threats. So, despite the convenience of email, you should be extra careful, especially when sending sensitive data.
