We live in a world of increasing challenges as we face more people working from different places and devices. This new way of work, results in new opportunities for cyber criminals to compromise businesses’ communications. All companies must start thinking about their preparedness to prevent their customers’, investors’, and employees’ information being hacked. In today’s article we’ll talk about the main threats in cyber security for UCaaS, and how Microsoft technologies can prevent them.
Microsoft Teams, leader in the 2021 Gartner Unified Communications as a Service Magic Quadrant reports, is built on the Microsoft 365 and Office 365 hyper-scale, enterprise-grade cloud, delivering the advanced security capabilities customers expect.
Here are some of the Microsoft Teams common security threats:
1. Compromised-key attack: Refers to the use of a key that an attacker has stolen to gain access to a secured transmission. This key allows the attacker to decrypt data that is being sent. The sender and receiver are usually not aware of the attack.
2. Network denial-of-service attack: A distributed denial-of-service (DDOS) attack occurs when the attacker prevents normal network use and function by valid users.
3. Eavesdropping: Eavesdropping occurs when an attacker gains access to the data path in a network and has the ability to monitor and read the traffic.
4. Man-in-the-middle attack: A man-in-the-middle attack occurs when an attacker reroutes communication between two users through the attacker’s computer without the knowledge of the two communicating users.
How Teams handles common UCaaS security threats
Advanced Threat Protection (ATP)
ATP is available for Microsoft Teams, along with SharePoint and OneDrive, and allows users to determine if content is malicious in nature and block this content from user access.
End-to-end encryption (E2EE)
With end-to-end encryption, only two endpoint systems will be involved in encrypting and decrypting the call data. No other party, including Microsoft, has access to the decrypted conversation.
Azure Sentinel and Microsoft Teams
Sentinel lets administrators do security management in one location, from Third-party devices to Microsoft Threat Protection, and Microsoft 365 Workloads.
Passwords are the most common method of authentication, but they are also the most vulnerable. To provide an additional level of security for sign-ins, use multi-factor authentication (MFA), which requires both a password and an additional verification method such as:
- A text message sent to a phone that requires the user to type a verification code
- A phone call
- The Microsoft Authenticator smart phone app
- Other methods available with hybrid identity and federated authentication
Global or Security Administrators can create policies to handle suspected malicious attachments and prevent them from being sent to users.
Microsoft Secure Score is a measurement of an organization’s security posture, with a higher number indicating more improvement actions taken. So, by following the Secure Score’s recommendations you can protect your organization from threats.
Certainly, cyber crime businesses will continue to grow, so companies must embrace modern cyber security practices while enabling digital communications. In conclusion, prioritizing UCaaS security is more relevant in 2022 than ever before.
