Email security, cyber resilience, Microsoft Defender for Office 365
Such a slogan like “be careful” is quite exiguous and windy in IT security. For example, it is very difficult for a user to determine if a link is harmful. And let’s face it, it’s not his/her business at company level either. The user is not expected to verify the authenticity of URLs one by one, as it is his job to “produce”. The tasks and their responsibility belong to IT management, as not to let emails containing camouflage, phishing, or other threats to enter the system. Or if it has happened yet, they have to launch threat hunting and to manage remediation on the whole system as soon as possible, and last, but not least to block the connection to the URL used to steal the data.
OF COURSE, PERSONAL DEVELOPMENT IS ALSO NEEDED
Competency development is extremely important and it is easily acceptable for a corporate employee to be aware of cyber threats. One of the cornerstones of cyberresilience is regular security education. However, no one can be expected to perform basic IT security functions when reading emails. Recently it is not necessary, because email security or a secure web gateway is the adequate tool to test URLs, attachments, codes in a cloudy environment where they can be “unleased.” Also, there are services in advanced security systems that even learn from external sources about threats which have already been identified and classified elsewhere, thus not allowing them into the system.
WELL, WE DON'T JUST GET EMAILS
And the story doesn’t end here, because what if someone from the company’s domain wants to send out sensitive data? Or maybe malicious codes? And even it may happen that sending emails out is not even be conscious. Where spam comes and goes freely in the mail system, there may be plenty of potential other security issues to be exploited, that cybercriminals, no doubt take advantege.
Let's see what you can do to keep your email safe!
In today’s evolving threat environment, business email is the primary attack vector for cybercrime, therefore the effective email protection is a key element of any security strategy.
Email security describes various procedures and techniques for protecting email accounts, content, and communications from unauthorized access, loss, or compromise. The reason of applying email protection in the bussines is that email is more often used to spread malware, spam, and phishing attacks.
In the first quarter of 2022, Microsoft participated in an evaluation of e-mail security solutions conducted by SE Labs, a test lab focused on assessing the effectiveness of security solutions. In their latest Enterprise Email Security Services test, email security vendors were evaluated based on a series of real-time email attack scenarios. Microsoft has received an AAA Protection Award for Microsoft Defender for Office 365, the highest award vendors can achieve in this test. In a report by SE Labs, Microsoft Defender for Office 365 blocked 97 percent of emails that contained a threat. The SE lab report confirms that Microsoft Defender for Office 365 used by companies worldwide, which is part of Microsoft Defender 365, is a good choice for protecting email.
An email protection solution alone will not yet provide complete protection. Here, too, it is worth providing multi-layered, multi-spectrum protection and control with reaction capability for higher level system security.
But it is also worth spending a lot of time on competence development. Improving skills of employees helps a lot, and you don’t have to think about deepening technology here! The point is not for someone to know how to start a brute force attack, or what a man-in-the-middle is when logging in to an evil twin hotspot, but rather how to behave in situations that raise various trust issues.
And here comes the most important part of today’s blog: if human is the weakest element of safety, strengthen it and let it be the strongest! There is no simpler and cheaper solution.
Email protection uses such technologies to control malicious threats to incoming e-mail and to encrypt or secure outgoing e-mail traffic, that protect mailboxes, data, users, and organizations from cyber security attacks and schemas, and from compromising business.
