Best Practices for Enhanced Protection

As businesses continue to rely on digital platforms for communication, collaboration, and productivity, the need to prioritise security has become paramount. Microsoft 365, a comprehensive suite of cloud-based productivity tools, offers a wide range of features to enhance productivity. However, it is crucial to ensure that the security of your Microsoft 365 environment is robust enough to protect your sensitive data and maintain the confidentiality of your operations. In this blog post, we will explore some best practices to strengthen the security of your Microsoft 365 and safeguard your organisation from potential threats.

Multi-Factor Authentication

Multi-Factor Authentication (MFA) is a security feature that provides an additional layer of protection to your Microsoft 365 environment. It requires users to provide more than one form of authentication to verify their identity when logging into their accounts.

The traditional method of authentication involves using a username or email address along with a password. However, passwords alone can be susceptible to various security risks, such as phishing attacks, keyloggers, and data breaches. If an attacker manages to obtain or guess a user’s password, they can gain unauthorised access to the account.

MFA addresses this vulnerability by introducing an extra step in the authentication process. In addition to the username and password, users are required to provide another form of verification. This typically takes the form of a temporary, one-time verification code that is sent to a registered mobile device via a text message, phone call, or a dedicated authenticator app.

By implementing MFA, even if an attacker manages to obtain a user’s password, they will still need access to the user’s mobile device or the authenticator app to complete the authentication process. This significantly reduces the likelihood of unauthorised access to an account, as it adds an additional barrier that an attacker would need to overcome.

Regularly Update and Patch

To protect your Microsoft 365 environment from emerging security vulnerabilities, it is crucial to stay up to date with the latest updates and patches released by Microsoft. These updates often include security fixes and improvements that address known vulnerabilities. It’s important to enable automatic updates or establish a process to regularly check for updates and apply them promptly to keep your environment secure.

Implement Data Loss Prevention (DLP) Policies

Implementing Data Loss Prevention (DLP) policies is an essential security measure to protect sensitive data within your Microsoft 365 environment. DLP policies allow you to define rules and actions that help identify, monitor, and protect sensitive information across various Microsoft 365 services.

Sensitive data can include a wide range of information, such as financial records, customer personally identifiable information (PII), credit card numbers, social security numbers, intellectual property, or any other data that, if exposed, could result in financial loss, reputational damage, or legal consequences. Here are the key components and benefits of implementing DLP policies:

  1. Identification and classification – DLP policies enable you to identify and classify sensitive data based on predefined patterns, keywords, or custom rules. For example, you can create rules to identify credit card numbers or specific types of confidential documents.
  2. Monitoring and detection – Once the sensitive data is identified and classified, DLP policies continuously monitor and scan various Microsoft 365 services, including email, SharePoint, OneDrive, and Teams, to detect any unauthorised sharing, accidental exposure, or inappropriate handling of sensitive data.
  3. Policy enforcement – DLP policies allow you to define actions to be taken when sensitive data is detected. For instance, you can block the sharing of sensitive information outside the organisation, encrypt emails containing sensitive data, or prompt users with warning messages when they attempt to share sensitive content.
  4. Incident management – DLP policies provide incident management capabilities, allowing you to track and investigate policy violations. You can generate alerts, reports, and notifications when incidents occur, enabling you to respond promptly and take appropriate actions to mitigate the impact.

By implementing DLP policies in Microsoft 365, you can significantly reduce the risk of data breaches and illegal exposure of sensitive information. It helps maintain compliance with data protection regulations, protects customer trust, and safeguards your organisation’s reputation. Additionally, DLP policies provide visibility into how sensitive data is handled, allowing you to identify potential vulnerabilities and implement corrective measures to strengthen security.

Utilise Advanced Threat Protection (ATP)

Microsoft 365 Advanced Threat Protection (ATP) provides strong security features to defend against advanced threats such as malware, phishing, and ransomware. ATP helps protect your association’s email, files, and collaboration tools by scanning attachments and links for potential threats, blocking malicious content, and providing real-time protection against emerging threats. Consider enabling ATP to fortify your Microsoft 365 security posture.

Educate and Train Users

Educating and training users is a critical aspect of maintaining a strong security posture within any organisation. Human error and lack of awareness are common vulnerabilities that can be exploited by attackers. By investing in regular security awareness training, you can greatly reduce the risk of security incidents and enhance overall security awareness among your employees. Here are some key points to consider:

  • Common threats – It’s important to provide training to users about common threats, such as phishing attacks, social engineering, malware, and ransomware. Educate them on how to identify suspicious emails, links, or attachments, and emphasise the importance of not divulging sensitive information to unknown or untrusted sources.
  • Password hygiene – Promote good password hygiene practices among your users. You should encourage them to use strong and unique passwords for each account, enable multi-factor authentication (MFA), and avoid sharing passwords with others. Teach them about the risks associated with reusing passwords across multiple platforms and the benefits of using password managers to securely store and manage their credentials.
  • Reporting procedures – Highlight the significance of reporting any suspicious activities or security incidents promptly. In order to effectively do this, establish clear reporting procedures and channels for users to notify the appropriate IT or security personnel if they encounter any potential threats or incidents. It’s encouraged to promote a culture of openness and assure users that reporting incidents will not result in punitive action.

Monitor and Audit Activity

Implementing robust and strong monitoring and auditing processes is essential for detecting and responding to security incidents promptly. Microsoft 365 provides various built-in security features, including auditing and activity logs, which allow you to monitor user activities, access patterns, and potential security breaches. It’s critical to regularly review these logs and leverage security analytics tools to identify anomalous behaviour and take appropriate action.


Strengthening the security of your Microsoft 365 environment is crucial for protecting your organisation’s sensitive data and ensuring smooth operations. By implementing best practices such as enabling multi-factor authentication, staying updated with patches, leveraging data loss prevention policies, utilising advanced threat protection, educating users, and monitoring activity, you can significantly enhance the security posture of your Microsoft 365 environment.

Remember, security is an ongoing effort, so it is essential to regularly assess and adapt your security measures to address evolving threats and protect your organisation’s digital assets effectively.
