Why is general security of the entire IT infrastructure not enough?
Simply because e–mail and cloud platforms have specific types of risks and at the same time completely different uses. They are dynamic, linked to a number of other tools and often not only employees, but also partners or suppliers have access.
That makes them the actan environment where:
– even a legitimate user can spread threats (e.g. by forwarding a phishing email –mail),
– data is easily leaked if the sharing settings are wrong,
– it is difficult to detect in time whether the activity is legitimate or malicious.
What types of threats e–email and cloud services are most often threatened?
- Phishing campaignsAimed at stealing login credentials through credible appearing e–emails.
- Malware spread via attachments or cloud links: The file looks harmless, but but contains malicious code.
- Insecure data sharing: For example, a document shared “for everyone with a link” can to be abused.
- Access from suspicious locations or facilities: Indication of a compromised account.
What modern e protection looks like–email and cloud environment?
Effective defence doesn’t just mean installing antivirus or deploying e–email filter. Really advanced protection involves a combination of technology, regular analysis and continuous supervision. Solutions such as SecuRadar Complete work with the concept of Zero Trust – i.e. they do not assume that the internal user is automatically trusted.
Key elements of this protection:
– Detection of suspicious activity: E.g. unusual data sharing in SharePoint or repeated upload of suspicious files to OneDrive.
– Monitoring over e–e-mail communication: Detection of phishing attempts, Detecting malicious attachments and non-standard behaviour in Microsoft Exchange Online.
– Cloud storage protection: Tracking interactions in apps like Teams, SharePoint or OneDrive – including prevention of “Shadow IT”.
– Automated incident classification according to the MITRE ATT&CK framework: Helps to prioritize threats according to their severity and attack target.
Can advanced protection also simplify the work of users?
Yes, and this is perhaps the biggest benefit of modern solutions. Thanks to behavioural analytics (UEBA), it is possible to for example, to reduce the number of false alarms and focus only on relevant incidents. Users of are not overwhelmed by safety warnings, while being confident that their working environment is protected. In addition, interactive Threat Dashboards give the IT team an immediate overview of security status and can react quickly. Everything is integrated into the Microsoft 365 environment – without the need for additional applications or user intervention.
How do I know if my company has a problem?
Here are two questions that will give you a clue:
1. Do you know who last shared a file via OneDrive outside the company? If you answered this question you don’t have an answer within a few seconds, it means you don’t have enough visibility over cloud activity.
2. You have an overview of who has accessed your e–email from an unusual IP address? Such as activities may indicate a compromised account. Without advanced monitoring, they often remain unnoticed.
How to proceed?
If you are unsure about the level of protection for your communications and cloud storage, the first step is to can be free security assessmentto help you assess the state of Microsoft 365 environment – including e–mail, OneDrive, SharePoint or Teams. System4u offers this service as part of the tool SecuRadar – without interference and with clear output for more decision-making.
Protecting communications and storage is no longer just about antivirus. It’s about context, analytics and the ability to react in real time.
And therein lies the difference between basic and truly effective defense.
