Email is one of the oldest yet most important tools relating to conducting business communication today because it allows the sharing of confidential information, various documents, and transactional data.
At the same time, email is such an attractive target to expose for cybercriminals, and steps must be taken to ensure company emails are kept secure in order to safeguard against data breaches, malware, and other dangers to the integrity of cyber security.
In this article, experts from TMI have discussed the need and purpose of email security, the baselines for implementing measures, and additional ways to set up a better protection system for your organization’s emails.
Key Takeaways
Implementation of strong passwords and two-factor authentication to make the email accounts less vulnerable to unauthorized access.
Use of Encryption: End-to-end emails while in transit to avoid exposure of sensitive information to interception and unauthorized eye-bawling.
Advanced spam filters and secure email gateways integrating advanced filtering are to be used, which can easily block emails that are malicious and greatly reduce the problem of phishing.
Authentication Protocols such as DMARC, SPF, and DKIM should be implemented to ensure the authenticity of the sender and prevent spoofing.
Regularly update email software and security patches to be safe from known vulnerabilities as well as new threats out there.
What is Email Security?
Email security is a strategy and technologies comprising strategies, aiming to protect email accounts, content, and communication from unauthorized access, loss, or compromise.
For instance, it means the content of an email should not get subjected to risks like phishing, malware, spamming, compromise at rest or in motion, and impersonation to ensure its lifecycle has confidentiality and integrity.
Why Email Security Is Important?
Email security matters for the following reasons:
- Data Protection: In most cases, sensitive corporate information such as commercial information, financial details, trade secrets, personal details of employees. This information is communicated through email. This data should remain secure from a breach.
- Helps Guard against Cyberattacks: Email is one of the easier ways through which cyber-attacks, including phishing, malware, and ransomware, are spread. Strong email security can help avoid letting such threats creep into the company’s technological infrastructure.
- Regulatory Compliance: Most industries are regulated under laws, which require them to protect sensitive data. Strong email security is relying on the maintenance of proper compliance with laws such as GDPR, HIPAA, and CCPA now highly needed today.
- Business Continuity: Cyber incidents can be disruptive to business. Securing email ensures continuity and eliminates expensive downtime.
How to Protect a Company Email?
1. Strong Authentication Measures
By using strong passwords and 2FA, one reduces the chance of unauthorized access significantly. If a password is compromised, there will still be an extra verification step with two-factor authentication.
2. Use Encrypted Connections
Encrypting email communications ensures that data remains unreadable to unauthorized parties during transmission.
Secure email gateways (SEGs) and Transport Layer Security (TLS) can protect email content from interception
3. Email Filtering and Anti-Spam Solutions Deployment
The most advanced spam filters and email gateways are able to filter out and curb the action of malicious emails even before reaching inboxes.
This means that it can quarantine ill-sent or suspicious emails and hence reduce the chances of a phishing attack or malware exposure.
4. Email Authentication Protocols Implementation
DMARC, SPF, and DKIM are designed to help authenticate legitimate senders of email and, therefore, prevent the possibility of email spoofing.
This makes sure emails affirming to be from your domain actually come from authorized servers.
5. Keep Up with Software and Security Patch Updates
This is why it is important to always keep software updates for email and antivirus.
Many cyber attackers use the exploits that work on the dated software, rendering regular software updates helpful in protecting against threats already previously identified.
6. Back up Emails and Important Files
Regular backups allow restoration of data in the event that your computer gets attacked by ransomware, for example.
Physical isolation and regular testing of backups help to increase the reliability of backups.
How Else to Improve Security in Emails?
Training and Awareness
In email security, best practices are very necessary, and this awareness needs to be instilled in employees.
Such awareness programs need to equip the employees to be able to recognize phishing attempts, impregnable handling of attachments, and being in a position to report such emails.
Virtual Private Networks (VPN)
Encouraging access to email with VPNs, especially over public Wi-Fi, secures the connection and prevents interceptions of sensitive information.
Implementing Strong Email Policies
Clear policies on the use of email, such as prohibiting personal use of company email accounts and guidelines on handling sensitive information, can reinforce security measures.
Advanced Threat Detection Solutions
Finally, deploying solutions that utilize machine learning and artificial intelligence will identify and mitigate sophisticated threats that traditional security measures might miss.
What other advanced techniques can be used to improve Email security?
- Security solutions that integrate machine learning and AI can provide threat detection in real-time and dynamically move with new and evolving cyber threats.
- Email data loss prevention (DLP) tools can monitor and control the transfer of sensitive information, preventing accidental or intentional leaks.
- Further improving email security can be conducted with the help of blockchain technology in ensuring the integrity and non-repudiation of the email message through the creation of email transactions.
The overall email security can be enhanced by creating a culture of security mindfulness, where employees report suspicious activities using the available tools without a fear of repercussions.
