The landscape of the battlefield between email threat protection solutions and an attacking side is continually changing, as criminals develop new ways of gaining unauthorized access to organizations' corporate emails.
On the one hand, enterprises and their employees have always been the key targets of cybercriminals. Stealing, exposing, and selling of personal, corporate, financial, and other types of sensitive information, on the other hand, have always been the key goals of cyberattacks.
Since email is undoubtedly a #1 business tool for communication, no surprise, it is also a #1 vector for cyber-attacks (91%).
While a threat protection system comes with basic options, there is only one way email can be protected — and that is by implementing a strong multi-layered solution that’d be on top of that system and provide ultimate email security.
Email threat is a broad term.
In a nutshell, it is a whole package of email vulnerabilities cyber-criminals use to attack users’ Inboxes. The definition of advanced email threat relates to the complex of sophisticated cyber-attacks.
There are many types of cyberattacks, but the most popular are:
To understand the sophisticated nature of such attacks, suffice to say that they can stand in close interdependence.
For instance, an attacker could use an email bomb attack to send numerous emails to the same email address to overflow the mailbox to cover the tracks of other malicious actions or make the user stop using the email address.
This, in turn, can result in an email cluster bomb attack — when a particular email address is signing up to several email list subscriptions. Unsubscribing from those lists carries the risk, as clicking on an unsubscribe link can lead to malware to infect a device in its attempt to hijack sensitive information.
When email constitutes considerable menace and poses a critical danger for the company’s security, the next question naturally suggests itself.
Criminals are attempting to access both personal and company information.
The typical tool used are phishing emails. Such emails encourage you to visit websites requesting personal information.
Because the attacks' methods are different, email threat protection must include multiple layers of defense, combating standard threats like malware, viruses, spam, and targeted email attacks like phishing, BEC, VEC, EAC.
These attacks are designed to trick users into clicking on a malicious link, sharing confidential information, or even worse — wiring money to the fraudsters when selling or purchasing real estate.
By utilizing high-pressure email threat methods, cybercriminals urge employees to click, download, and open malware and virus-injected attachments.
There are some salient features by which you can identify a social-engineered email:
The red flags in the email might look the following:
Some email security systems solely rely on a couple of anti-malware detection services. While this can be less than non-effective, cybercriminals use specific ways to avoid detection, enabling them to beat traditional defenses.
What cyber fraudsters do is adapt to the detection systems. Files such as Microsoft Office, PDF, and image files can include potentially malicious active content, such as macros and scripts.
Although Secure Email Gateways might be a useful tool for filtering inbound and outbound emails for phishing, malware, and spam, there are thousands of new vectors of attacks, sophisticated techniques and common vulnerabilities and exposures (CVE), that can easily ‘solve the issues’ of standard email filters.
As a result, malicious emails almost certainly will remain unnoticed in the Inbox folder. In the long run, that fact could cost you time, money, and resources [with a single click of a mouse].
Email threat protection for Office 365 has the built-in spam filters and cloud-based email filtering service. It helps protect your organization against unknown malware and viruses by providing zero-day protection and includes features to secure your organization from harmful links.
But this is not enough for full email threat protection. The scan system cannot recognize malicious scripts, macro files, and hidden threats embedded in email attachments.
A comprehensive email threat protection is obtained only if you increase its capabilities.
This can be achieved with such a component as an add-in.
Add-in is a software program that extends the capabilities of the main program. In terms of email, the main program is Microsoft Outlook.
Besides broaden functionality and enhanced data encryption methods, add-in provides:
Add-in will allow you to enhance your email security by encryption of confidential data, but it will also help you to accomplish compliance with local regulations and corporate policies (which, again, is impossible within standard functionality).
The good way to improve email business communication flow is to secure it. This evenly elaborates on email content and its attachments.
If a link in a body message is unsafe, the user must be warned not to open this link, or that opening one may harm the organization's confidential data.
Administrators’ control must be provided, so in case of any minor potential threat or if any suspicions relating to attachment or email itself arise, administrators can track which users clicked a link and when they clicked it.
Also, employees themselves can improve email business communication flow through constant training and education to know how to recognize potential email threats.
Another effective way to improve the flow and enhance a company's overall productivity is to ensure that email communication happens only between individuals whose identities were confirmed, and authorization permissions were granted.
The StealthMail cloud-based solution delivers an unprecedented level of email security that procures enterprises with advanced encryption algorithms, which reliably protect sensitive data from the dangers of traditional email communication channels.
Flexible and granular controls enable administrators to set necessary security policy and rapidly apply it to improve security and compliance.
StealthMail provides ultimate email security services, which include:
