Security Tips for Office 365

Security Tips for Office 365

Security is at the forefront of most business strategies, with many companies turning to managed service providers to bring forth solutions that will keep their company data safe and any intruders out. Last year larger organisations such as  hospitals, banks and governmental institutions were plagued by a number of major security breaches, and it is no surprise that security is one of the top priorities for most organisations this year.

As Office 365 is used by 90-95% of companies, it is the largest, and most obvious target for hackers as it is the largest source of storing information, especially sensitive information

  • 17.1% of files in OneDrive and SharePoint online contain sensitive information including payment card numbers, business plans and financial records.
  • 58.4% of sensitive data in the cloud is stored in Microsoft Office documents.


In order to ensure sensitive information is hack proof, simple security measures such as; creating complex passwords, using different passwords for cloud applications, only using secure network connections and backing up your data can work to increase the security and decrease chances of a cyber attack.

Below are more tips that can help to secure Office 365, and keep your data safe while ensuring optimal productivity

  1. Enable Office 365 Safety Tips: The Office365 safety Tips are pop-up dialog boxes that provide appropriate security information for users when they open a program. These tips can also be customized to your company policies as a reminder to users about activities governed by those policies.
  2. Change administrative defaults: By keeping administrative defaults in Office 365, this could put your organization at risk, so a best practice for your IT department should be to change default settings where possible when installing a new piece of software. If you have already installed applications but have not changed the defaults, you can still change them, it’s just more efficient to do it during the installation process.
  3. Implement security policies that govern data storage: It’s not uncommon for users to save data from Office 365 to the cloud via Dropbox, Google Drive, and other cloud storage providers. Any cloud services that are not monitored and controlled by your organization are a point of risk for your data, so be sure that users understand using those services is against company policy.
  4. Enable data encryption to prevent data from being compromised during transit. Some versions of Office 365 include data encryption, whilst others do not. If you are using a version that includes encryption be sure it’s enabled. For versions without encryption, a third-party encryption capability is required to ensure that your data is safe when in motion and at rest.

Microsoft Office 365 is one of the most used productivity suites because it’s an incredibly valuable tool for organizations within any industry. However, it’s important that you understand the risks of the application to your organization when it’s not installed and managed right. Take the time to adjust administrative defaults, tweak settings, and properly train users so your company’s installation and use of Office 365 doesn’t increase your attack surface.
