Why Your Business Needs Better Email Security
- by Brittany Day
Email threats are ever-evolving. Cyber criminals are persistent in their efforts, continually working on perfecting their craft - employing new, increasingly sophisticated methods, tactics and techniques to deceive users, evade security defenses, and ultimately, get paid. Too many businesses are struggling to adapt and adjust to this modern digital threat landscape, or have failed to make email security the priority that it needs to be - leaving users and key assets at great risk.
While it is critical that users are alert and educated on the threats that they face online, users cannot be expected to detect today’s advanced threats without fail - making the implementation of proactive, layered email security defenses more critical than ever.
The majority of traditional email security defenses have fallen behind, unable to keep pace with rapidly evolving threats. In this article, we’ll take a closer look at modern email risk, and examine why your business needs better email security in 2021.
Email is the preferred attack vector among cyber thieves, and is used to initiate over 90% of all cyberattacks and breaches. It is no secret that 2020 and into 2021 has been a challenging time for all companies, and in many cases email security has been put on the back burner. Despite the lack of IT resources and cybersecurity expertise that many businesses - especially SMBs - are currently experiencing, now is certainly not the time to overlook the importance of effective email security.
Email security is not a commodity. Rather, it is more essential to robust cybersecurity and business success than ever before. The pandemic has provided a golden opportunity for cyber thieves, interested in benefiting from the chaos. To accommodate remote workers, many organizations have hurriedly migrated to vulnerable cloud platforms like Microsoft Office 365 and Google Workspace. The static, single-layered email security defenses built into these platforms are unable to protect against today's sophisticated attacks like targeted spear phishing and ransomware, and there are no preventative measures in place to safeguard users and critical data against zero-day attacks. Rushed deployments frequently lead to misconfiguration of vulnerabilities, leaving users even more susceptible inOffice 365 and Workspace. Attackers have taken note of this trend, and are capitalizing on inadequately secured cloud email to steal credentials and compromise accounts. Despite existing protection, 40% of Office 465 users have experienced credential theft nevertheless.
The Modern Email Threat Landscape
While email-borne cyber attacks were once simplistic, “cookie-cutter” phishing scams exploiting unaware users, those days are far behind us. Modern email threats have become so sophisticated and targeted that it is now much harder to blame the user for falling for a scam. After all, even the most security-aware individuals can be fooled by these dynamic attack campaigns.
Cyber criminals are getting better at disguising themselves - devoting extensive time and resources to social engineering research. Once a target has been selected, threat actors scan all their social media pages to learn what type of content they are engaging with, who their friends are, who their former co-workers are, and more. In some cases, criminals will even create fake profiles to connect with potential targets and obtain more information that can be used to craft highly convincing spear phishing and whaling emails. Not only does the information obtained through social engineering make these email attack campaigns appear more credible, it also helps them evade spam filters, since each fraudulent email is unique.
Malware and ransomware attacks are quickly advancing in complexity and sophistication. Traditionally, the same malware was sent to many users, and once these viruses were identified, security companies used the file’s signature to identify new attacks. This tactic is ineffective in the modern digital threat environment, as attackers now generate a unique file for each recipient.
While the majority of primitive malware attacks relied on executable files to infect victims’ systems, malicious hackers are increasingly leveraging stealthy fileless techniques which exploit legitimate, trusted system tools to evade traditional security defenses. Because fileless malware does not use executable files and, therefore, does not have a signature, the majority of signature-based antivirus software and simplistic email security solutions are unable to detect this emerging exploit. This enables cyber thieves to quietly sit on systems for extended periods of time, eavesdrop on their targets and steal confidential business information. Ponemon Institute reports that fileless attacks are 10 times more successful than file-based attacks.
Other pay-loadless email scams that don’t involve malicious files - namely business email compromise (BEC) and email account compromise (EAC) - are also on the rise. These dangerous impersonation attacks involve a malicious hacker hijacking an email account and then sending fraudulent emails from the compromised account to steal sensitive information and money from victims. The FBI has disclosed that between June 2016 and July 2019, BEC has generated reported losses of $26 billion worldwide, and financial losses from BEC attacks alone have increased 136% over the past two years.
Modern Threats Demand Modern Solutions
As the email-borne threats that businesses and users face on a daily basis continue to advance, the methods and technologies used to detect and combat them must keep pace. However, security defenses have fallen far behind - frequently allowing malicious emails to slip through the cracks leading to data theft, financial loss, decreased productivity and reputation damage.
Due to a lack of understanding or inadequate prioritization of security, it is not uncommon for businesses to implement simplistic, single-layered security software that takes a static rule-based approach to identifying and blocking malicious mail. This technology relies on seeing the same virus or spam message across many customers - an outdated approach that is largely ineffective nowadays. According to Ponemon Institute, 80% of SMBs report that malware has evaded their antivirus software.
Another common email security mistake is relying on endpoint security alone to secure business email. Solutions deployed at the perimeter are often ineffective, as they don’t provide persistent, end-to-end protection and are typically blind to internal threats like fraudulent employee-to-employee messages or compromised accounts. Endpoint security solutions also carry a selection of other risks. For instance, these solutions are more vulnerable to zero-day attacks than network security solutions because they don’t have the benefit of the worldwide resources that are available to network security systems. In addition, an organization’s endpoints, like desktops, laptops and cell phones, can be viewed as its last line of defense against cyber attackers, and if something goes wrong at an endpoint, it’s an easy target for malicious hackers. For these reasons, endpoint security strategies are both inefficient and ineffective in protecting against modern email threats.
Stay Ahead of the Latest Threats with an Innovative, Fully-Managed Email Security Solution
The business email security market is rapidly shifting in favor of multi-layered machine-learning-based systems that learn and adapt to the increasingly dynamic and targeted attacks that challenge their defenses. Successful modern email security systems must learn each customers’ environment and detect anomalies in real-time in order to prevent attacks. Static, rule-based solutions are no longer sufficient in safeguarding the inbox.
