As email is at the center of business communications for most enterprises, this channel must be secured by implementing email security best practices.
FREMONT, CA: Email remains one of the most popular vectors of attack against businesses. The significance of incorporating email security best practices cannot be overstated, particularly considering that most companies depend primarily on this channel for regular business communications.
Cybercriminals can easily exploit corporate email weak points through dispersed denial-of-service (DDoS) and phishing attacks, malware and ransomware, and employee errors.
Poor email security can result in loss of data and downtime and leakage of confidential information about a company's finances, intellectual property, employees, and customers. Lack of control over such sensitive documents can result in revenue and market share losses, fines, and reputational damage. This is particularly true for those working in highly regulated industries like finance, law, publishing, education, and healthcare.
Irrespective of this, businesses have yet to build a cyber resilience approach that prioritizes email security. To fight against every type of attack, specialized standalone email security solutions are available. On the other hand, IT departments require complete visibility and control over the enterprise's email security strategy and defense. It is the only way they can ensure they are secured against all types of attacks.
Here are few emails security best practices to include in the company's overall cybersecurity strategy.
Improve the endpoint and email security hygiene
Employees may be aimed with phishing emails, spam, and malware that, if opened, may attack their devices and offer gateways for hackers to access the entire enterprise network.
To combat this, businesses should deploy endpoint email security software in combination with anti-virus security features. These can filter and block malware or spam emails from unknown senders and IP addresses and clean the infected systems that are trying to send outbound spam.
Secure the email content with encryption
To fully secure the email content, both the content and attachments must be encrypted while in transit and rest in the inbox. Popular email platforms, such as Gmail, typically lack the necessary enterprise-level email encryption to protect organizations against every cyber threat fully. To the level that these platforms help encryption, it is only possible if both the sender and the recipients have specific extensions.
Document security solutions can also help prevent unauthorized access to sensitive information shared through email.
Implement email server protection
It is possible to hack mail services and even damage the servers that store and send emails. Spam and DDoS attacks on these servers can disrupt the transfer and processing of regular email.
It is critical to collaborate with the IT team to provide them with all the information they need to help secure the email servers. Distinguishing authentic emails from spam, phishing attacks, and other threats in the initial stage can help protect intellectual property and sensitive company information.
