Five diagnostic tools that help you identify Microsoft 365 vulnerabilities

Users access and share files so easily on the cloud that it can make your business susceptible to many online threats. Identity theft, infection or attack are some of those risks.

Indeed, 94 percent of cyberattacks start with email. Yet sixty percent of breaches have involved vulnerabilities where a patch was available but not applied.

But you can do more to secure your business.

Microsoft 365 has a range of tools that give your business necessary visibility. They can help you sense-check your setups, and even cut chinks in your data protection armour.

Let's have a look at our top five recommendations.

1. Zero Trust Security

Rather than believe everything behind the firewall is safe, Zero Trust Security will assume a breach and verify each request as though it originated from an open network.

Here are some other features of Zero Trust Security:

  • Verifies access based on all available data points. These include user identity, location, device health, service or workload and data classification
  • Uses Least Privileged Access to limit user access with just-in-time and just-enough-access (JIT/JEA). This helps to secure both data and productivity
  • Minimises blast radius for breaches and prevents lateral movement. It does this by segmenting access by the network, user and device.
2. Secure Score

Microsoft Secure Score is a security analytics tool that lessens the risk of hacking or a data breach.

You can see a secure score in the Azure portal pages as a percentage value, and you can review the Security Center's recommendations for the actions necessary to raise your score and boost your security.

Your score only improves when you action all the recommendations for a single resource within a control.

3. Microsoft Defender

Microsoft Defender stops attacks with automated, cross-domain security and built-in AI.

The tool automatically analyses threat data across domains and builds a comprehensive picture of each attack in a single dashboard.

The powerful automation in Microsoft 365 Defender can detect and stop attacks anywhere in the kill chain. This removes vulnerabilities and returns the system to a secure state.

4. Microsoft Cloud App Security

Microsoft Cloud App Security is a Cloud Access Security Broker (CASB) that supports various deployment modes. These include log collection, API connectors, and reverse proxy.

CASBs act as a gatekeeper to broker access in real-time between your enterprise users and the cloud resources they use. This can happen wherever your users are, and whatever the devices they're using.

They do this by:

  • Discovering and providing visibility into Shadow IT and app use
  • Monitoring user activities for anomalous behaviours
  • Controlling access to your resources
  • Providing the ability to classify and prevent sensitive information leaks
  • Assessing the compliance of all your Microsoft and third-party cloud services.

5. Conditional Access

Conditional Access policies at their simplest are if-then statements. If a user wants to access a resource, then they must complete an action.

It's a new level of authorisation, known as 'informed access', in which the system will know that a given user is real, compliant and trusted.

By using Conditional Access, you can apply the right access controls when needed to keep your organisation secure.

Supercharge your security measures

Is your business ready to keep pace with the growing list of cybersecurity threats?

The right security tools are vital for those responsible for developing and managing software. They will put your M365 operations on the road to watertight security and avoid a potentially devastating blow to your business.

Managing these tools themselves isn't always possible. In which case, Claranet can help your business adapt and stay secure.
