EDITOR ’ S question mail remains one of the biggest
E cybersecurity threats to businesses of all sizes . Organisations now have more connections to their networks , with users accessing resources and systems from new devices and disparate locations . They also have more web applications , money stored in more online sites , social media accounts and new machines to secure , like Internet-of-Things ( IoT ) devices . Email security best practices for employees can help stop email-borne threats , prevent the latest attack vectors and reduce pressure on organisations ’ already overburdened IT teams .
Train your staff in cybersecurity awareness
Employees are an organisation ’ s first line of defence against email-borne cyberattacks . Cybersecurity awareness training helps employees know the threats they face , which reduces an organisation ’ s cyber risks and increases the chances of keeping their data secure . Make sure employees understand how to spot potential signs of an attack and the consequences of not following email security best practices .
Use Two-Factor Authentication ( 2FA )
Relying on passwords alone is not enough in the modern cyberthreat landscape . Users should harden their email accounts using 2FA or Multi-Factor Authentication ( MFA ), which adds an extra layer of security . This could be a variety of methods , such as entering a one-time code sent to their smartphone , a one-time password ( OTP ) sent via SMS , or using an authenticator app that displays a unique code or biometric verification like their fingerprint .
Better manage passwords
Organisations should ensure that all employees use a unique password for each account and change their passwords regularly . Deploying password management software also helps , as users no longer have to worry about remembering long , complex passwords to access their accounts .
Beware of phishing emails
Phishing attacks are one of the biggest security threats businesses face . Organisations can prevent these attacks by combining email security best practices and employee training with technology . This includes firewalls , Secure Email Gateways ( SEG ), sandboxing and Uniform Resource Locator ( URL ) threat defence technologies that scan for malicious links , content and attachments . Employee training also increases phishing awareness , as users learn to recognise what phishing emails look like and how to avoid them .
Encrypt email
Email encryption ensures that emails are only received and read by the person they were intended for . It also gives email senders more control , including revoking access to messages sent to the wrong person and seeing when emails are opened and who sent them .
Prevent data leaks and breaches
The main goal of email security best practices is to prevent breaches and data leaks . Employees should also avoid other security risks , such as using public or open Wi-Fi networks , and take advantage of tools like Virtual Private Networks ( VPNs ) that encrypt their browsing sessions .
Implement strong email defences
All of these security best practices are backed by strong email defences . This includes deploying firewalls and SEGs to protect employees from malware and phishing emails and securing organisations ’ email networks from harmful or malicious content .
By taking a proactive stance towards email security and implementing comprehensive measures tailored to their specific needs , organisations can minimise risks , alleviate stress and ensure the confidentiality and integrity of their communications .
Employee training also increases phishing awareness , as users learn to recognise what phishing emails look like and how to avoid them .
