Microsoft’s Office 365 is a robust productivity and collaboration tool. Businesses are particularly drawn to its advanced features, flexibility, and cost-efficiency. But like other cloud-based platforms, it’s not immune from security risks.
Businesses typically use SharePoint Online and on-premise SharePoint sites to store sensitive data like personally identifiable data. Failing to secure SharePoint content against unauthorized users is one way to expose your data and your business to malicious actors. And for companies that have to comply with regulatory authorities, there are serious consequences to data privacy non-compliance. To prevent this, limit administrator-level privileges and enable encryption. Set the necessary security restrictions per user for every application.
Train your staff
Launching phishing attacks and installing malware are two of the most common ways to hack into a system, but there are other paths of attack. Office 365 features like Microsoft Teams and Yammer, both of which connect to external networks, may serve as a medium for ransomware and other types of attacks.
Train your staff to identify potentially malicious files and URLs. Offer guidelines on how to handle and route sensitive files and communication to safe locations.
Organizations using Office 365 will not use all of the available applications. Businesses and users that have not been utilizing specific programs should note that some dormant applications may be vulnerable to attack. This is why it’s crucial to identify the apps that are not being used and have an administrator tweak user settings to restrict the availability of these unused applications.
Implement Cloud App Security
Like Google and other cloud services providers, Office 365 allows users to sync on-premise files to the cloud. However, this useful feature is not without security risks. If a file stored in your local One Drive becomes encrypted with malware, One Drive will view the file as “changed” and will sync to OneDrive in the cloud, with the infection going undetected.
Office 365 Cloud App Security, a subset of Microsoft Cloud App Security, is designed to enhance protections for Office 365 apps and provide greater visibility into user activity to improve incident response efforts. Make sure your organization’s security administrators set it up on your systems so you can detect and mitigate dangers as soon as possible.
Cybercriminals will continue to sharpen their hacking techniques, and your organization must keep up to protect your systems, apps, and devices. Call Kosh’s team of IT experts if you want to strengthen your business IT security.
