As email security is an ever-changing landscape, focusing on the most relevant issues in the threat landscape is where organizations need to start.
Most organizations depend on email correspondence as a primary means of communication when it comes to sharing classified information like customer account numbers, employee credentials, and confidential negotiations. However, businesses must keep in mind that all email exchanges may not be as secret as they believe. Organizations must ensure that their employees know email security and safety best practices to avoid this.
Certain email approaches are the most important and pressing topics to concentrate on. Since 2021, the following three types of attacks have been the most common:
- Credential Phishing
- Business Email Compromise (BEC)
According to a Cofense Phishing Defense Center experts report, credential phishing accounts for roughly 70% of all attacks, with BEC accounting for 7% and malware accounting for the remainder. Adding those figures to what gets handed up during a successful credential phishing attempt, it’s evident that preventing credential assaults should be a top concern. That does not mean that BEC and malware attacks aren’t essential to combat. Like the ensuing ransomware assaults, successful ones can be highly profitable for the attacker while excruciatingly agonizing for the victim.
There are a few basic methods that organizations should use to ensure that their email environment is protected against all three of these threats.
Credential phishing attempts attempt to obtain usernames and passwords by imitating actual login pages. Employees should be trained, as this is the first – and most significant – step in keeping an organization secure. Because the industry prioritizes volume over quality, real-world tradecraft training is essential.
This applies to BEC and malware risks as well. All of these attacks should be addressed first and foremost by staff training.
Guarantees that employees may report a threat as soon as they notice one. Because the Security Operations Center (SOC) can’t respond to what it can’t see, a reporting capability gives the SOC visibility into what’s coming via email. Select a simple reporting solution to set up, supports the organization’s many platforms, provides feedback to users when they report simulations, and, most crucially, sends the entire email to the SOC’s abuse box for analysis.
Develop a rapid response capability that enables organizations to immediately orient and respond to an actual threat. Security leaders can position the company to survive an attack if they recognize ‘bad’ and respond to ‘bad,’ neutralizing or restricting the threat. This applies to all recipients of a possibly harmful email, not just those who reported it. Most attacks send multiple emails to a firm, so if there is one, there are certainly more. It’s critical to find the others since the security teams don’t want threats lingering in users’ inboxes.
Finally, positioning skills that can evolve and recognize threats proactively minimize the danger further. SEGs (Secure Email Gateways) are one solution. However, threats continue to get through these gateways, necessitating the requirement for post-delivery analysis and response capabilities. Every SEG currently on the market has flaws. Companies have traditionally stacked SEGs to maximize the likelihood of one detecting a threat. A post-delivery analysis system based on information about what passes through all SEGs is functional and cost-effective.
Knowing the most common risks can help businesses decide where to focus their limited efforts and resources. All types of email assaults are risky, but companies can lower the risk of falling to any email attack tactics by implementing well-executed training, reporting, analysis, detection, and response capabilities.
