Are Employees the Weakest Link in Your Email Security Strategy?
- by Brittany Day
When determining your email risk and assessing your email security strategy, it is common for administrators and IT professionals to focus on the threat that outsiders pose to their organization. While this is a valid concern, the critical mistake that is made far too frequently is failure to address the role that employees play in many attacks and breaches.
Over 90% of cyberattacks are initiated via email, making effective email security a vital part of a business's overall security posture that is too often neglected. When email accounts are inadequately secured, employees are vulnerable to an array of dangerous threats including targeted spear phishing and ransomware. Just one employee clicking on a link in a phishing email or downloading ransomware has the potential to destroy a company, especially if that company is a small or medium-sized business (SMB). Email-borne attacks and breaches often result in significant downtime, decreased productivity, legal fees, recovery costs and ruined reputations, and 60% of small companies shut down within six months of falling victim to a data breach or a cyberattack.
The good news is there are numerous ways that you can mitigate the risk that employees pose to your business's security, productivity and success. While employee education and security awareness training are beneficial, user behavior is ultimately unpredictable. Thus, investing in a comprehensive, fully supported email security solution that creates a safeguarded environment around the user by preventing all malicious mail from reaching the inbox is the most effective way to prevent the devastation that human error can cause.
Best Practices for Forifying Business Email Against Employee Error
While employee behavior is ultimately unpredictable, there are certain measures that administrators, managers and IT professionals should take to help influence and motivate employees to make secure, intelligent decisions. These best practices for reducing the risk of employee error include:
- Invest in employee education and security awareness training about email threats and email security. In order for employees to make smart choices pertaining to email security, employers must equip them with adequate knowledge about email-borne threats and steps that they can take to prevent successful attacks. Employees are a companies’ last line of defense when it comes to securing business email accounts, and must understand the importance of their actions and the serious repercussions that a mistake such as downloading a malicious attachment or clicking through a malicious link can have.
- Encourage employees to choose strong, unique passwords, and implement 2FA whenever possible. Utilizing strong passwords that are not reused across different accounts is imperative to mitigating email risk. Taking a strict approach to email passwords reduces the risk of dictionary attacks and website exploits, which can have devastating consequences for employees and organizations. Implementing two-factor authentication (2FA) wherever it is available is also highly beneficial to an organization’s digital security posture and reduces the risk of account takeovers. The National Institute of Standards and Technology (NIST) has updated its guidelines to challenge traditional password security best practices. NIST now suggests that organizations not require that employees frequently change their passwords, as employees often respond to this requirement by storing their passwords in an insecure manner. NIST instead proposes the use of long passwords, which should be changed only if compromised.
- Emphasize the importance of thinking before interacting with any email message, and encourage employees to verify all suspicious emails that they receive. Clearly convey the message that it is better to be safe than sorry when it comes to email security, and if an email appears strange or suspicious in any way employees should not hesitate to report it to their manager or their company’s IT department.
- Invest in a proactive, multi-layered email security solution. Implement an email security solution that provides complete control of your email infrastructure and visibility into the threats targeting your organization and the security of your email. Choose a solution that is capable of protecting sensitive information and preventing data leakage with strong end-to-end encyption of both incoming and outgoing messages, is able to reliably identify and block advanced and emerging threats in real-time, and is fully supported by the ongoing expert system monitoring and maintenance required to ensure that users and key business assets remain safe in this heightened digital threat environment.
Insider Threats Are More Common & Costly to Businesses than Ever Before
Although it does account for the majority of insider-related incidents, human error or negligence is not the only concern when it comes to employees and security. Insider threats of all types, which come from individuals within an organization such as employees, former employees, contractors or business associates who have inside information about sensitive data, computer systems and security practices, are more prevalent and dangerous than ever before. According to Verizon, the number of insider-related breaches rises every year, despite the fact that over 70% of insider attacks are not reported externally.
The majority of insider threats fall into three categories:
- Malicious Insider Threats: An individual within an organization intentionally seeks to steal information, leak data, or harm an organization in any way.
- Careless Insider Threats: Employees or other insiders don’t understand an organization’s security policies or fail to follow security rules, putting the organization at risk of data leaks, malware infections and other types of malicious cyberattacks.
- Compromised Insider Threats: An employee’s email account is taken over by a threat actor through credential phishing or malware in order to compromise sensitive data or make fraudulent financial transactions.
Almost all insider threats involve email, making effective email security crucial in protecting businesses against not only malicious outsiders, but insiders as well.
