Managing extensive financial data and connecting through email communications? Beware, as you may be a prime target for cyberattacks. Email is the primary mode of communication in this digital business world.
So, how can you tell if the email received in your inbox is from a reliable source?
Are you sure that all your email communications are protected?
Accountants share a lot of confidential information via emails and a hacker could steal that information when no robust Email Security is in place. Using email passwords or a password management tool is not sufficient for complete email protection. Accounting firms need something beyond that – Email Security by a Managed security service provider.
It is evident that email serves as a common avenue for attackers to target firms. However, by implementing a few essential best practices within your accounting business, you can effectively remove yourself from the radar of email attackers. Let’s discuss it in detail.
Why is email the prime target for attackers?
When considering email providers, the landscape primarily revolves around two major players: Office 365 and Google. In terms of sheer numbers and targeting efficiency, businesses become logical targets, given that approximately 95% of them utilize one of these two platforms.
Consequently, it becomes a strategic imperative for firms to focus their efforts on these platforms, driven by the sheer volume of potential targets.
Platforms like Office 365 and G Suite are widely used, and they have specific login pages: Office365.com and Gsuite.com. This makes them attractive targets for hackers, who know that by compromising just one login, they could potentially access millions of businesses—a goldmine for them.
For accounting firms, email is particularly vulnerable because once a hacker gains access, they can wreak havoc. They can impersonate people, send out harmful messages, and essentially steal someone’s identity known as identity theft. It’s a serious issue we see happening all too often.
What is Email Security?
Email security refers to the collective measures put in place to protect email communication against unauthorized access, data breaches, malware, and other cyber threats. It involves various technologies, protocols, policies, and practices aimed at ensuring the confidentiality, integrity, and availability of email messages.
Key Components of Email Security
Encryption
Encryption ensures that the content of an email message is encoded in such a way that only the intended recipient can decipher it. This prevents unauthorized access to the email content during transmission and storage.
Authentication
Email authentication techniques such as SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) help verify the authenticity of email senders, reducing the risk of spoofing and phishing attacks.
Anti-Malware
Email security solutions often include anti-malware scanning to detect and block malicious attachments or links that could compromise the recipient’s system.
Anti-Phishing
Phishing attacks attempt to trick users into revealing sensitive information or downloading malware by impersonating legitimate entities. Anti-phishing measures help identify and block such fraudulent emails.
Data Loss Prevention (DLP)
DLP technologies monitor and prevent the unauthorized transmission of sensitive or confidential information via email. They can detect and block emails containing sensitive data or enforce encryption policies.
Access Controls
Implementing access controls ensures that only authorized individuals have access to email accounts and sensitive information. This may include strong password policies, multi-factor authentication (MFA), and role-based access control (RBAC).
Email Filtering
Spam and junk email filtering techniques help reduce the volume of unwanted or malicious emails reaching users’ inboxes, thus minimizing the risk of exposure to threats.
Security Awareness Training
Educating users about email security best practices, such as avoiding clicking on suspicious links or attachments and recognizing phishing attempts, is crucial for strengthening overall email security posture.
Email Archiving
Archiving email communications helps organizations comply with regulatory requirements, facilitates e-discovery processes, and provides a backup of critical communication data.
Continuous Monitoring and Incident Response
Regular monitoring of email traffic and prompt response to security incidents are essential for detecting and mitigating threats in a timely manner, minimizing the potential impact on the organization.

Implementing Email Security Measures in Accounting Practices
In the digital age, where communication primarily relies on email, accounting practices must prioritize the implementation of robust email security measures. Here are key steps to ensure a secure email environment within accounting firms:
Securing Client Communication:
Guidelines for Sending Sensitive Financial Information
It’s crucial to establish clear guidelines for accountants regarding the transmission of sensitive financial information via email. Encourage the use of secure file-sharing platforms or encrypted email services for exchanging sensitive documents such as tax returns, financial statements, or payroll information.
Encouraging Clients to Use Secure Channels
Educate clients on the importance of using secure communication channels for sharing sensitive data. Provide recommendations for secure email providers or secure client portals that offer end-to-end encryption to safeguard client information during transmission.
Regular Software Updates and Patches:
Importance of Keeping Email Clients Up to Date
Accountants should prioritize regular updates and patches for their email clients and related software. Software vendors frequently release updates to address security vulnerabilities and enhance the resilience of email systems against emerging threats.
Implementing Automated Patch Management Systems
To streamline the process of updating email software and ensure the timely application of patches, consider implementing automated patch management systems. These systems can automatically detect and apply software updates, minimizing the risk of exploitation due to unpatched vulnerabilities.
Monitoring and Detection:
Using Email Security Solutions for Real-Time Threat Detection
Invest in email security solutions that offer real-time threat detection capabilities, such as advanced anti-phishing filters, malware scanning, and behavioral analytics. These solutions can help identify and mitigate email-borne threats before they infiltrate the organization’s network or compromise sensitive data.
Establishing Protocols for Incident Response and Reporting
Develop comprehensive incident response protocols to guide accounting staff in handling email security incidents effectively. Ensure that employees are trained to recognize the signs of a security breach and know the steps to take in a suspected email security incident. Encourage prompt reporting of suspicious emails or security incidents to the designated IT security team for investigation and remediation.
