Microsoft 365 has been a popular target for threat actors, with 74% of small and mid-sized Indian businesses reporting ransomware attacks in the last few years. Despite setting the entire set of Microsoft 365 security defaults, a single hacked password or device might still expose your business to attack. The recent move toward remote work has only contributed to these security concerns.
Organizations are more vulnerable to breaches than ever before. While Microsoft 365 has clearly improved operational flexibility and efficiency, this increased agility has a downside. You are now dealing with an influx of sophisticated threats, all while under constant pressure to do more with less resources.
In the sections that follow, we will guide you through what are the security breaches and the top reasons to secure your Microsoft 365. Let’s begin
What are security breaches?
Security breaches in Microsoft 365 involve cyberattacks targeting email systems, cloud storage, and other collaboration tools, often exploiting vulnerabilities in user authentication, email phishing, and malware. Here are some statistics that show, how serious the issue is:
- According to IBM, The global average cost of data breach in 2023 was 4.45 million.
- Microsoft Office applications were the most commonly exploited applications worldwide at 61%, as per Statista report.
- 66% of organizations were hit by ransomware in 2023.
Types of security breaches in Microsoft 365
- Account Breaches: Cybercriminals exploit system weaknesses (e.g., software flaws, network vulnerabilities) to infiltrate employee accounts and access sensitive data. Signs include unusual device activity or logins from unfamiliar locations.
- Data Loss & Leakage: Sensitive information can be accidentally exposed via mistakes (e.g., wrong permissions, accidental sharing), leading to legal penalties and loss of trust. Microsoft 365 aims to inform users of breaches within 72 hours.
- E-mail Risks (Malware, Ransomware, Phishing): Malicious emails trick users into revealing credentials or downloading malware, which can destroy files, steal information, or lock accounts for ransom.
- Credential Theft: Cybercriminals steal login credentials through social engineering or brute-force attacks, gaining unauthorized access. This may lead to prolonged undetected breaches.
- Privilege Abuse: Insider threats occur when employees misuse their access, such as copying sensitive data, logging in during odd hours, or making unauthorized system changes. Malicious actions are harder to detect.
Top 8 reasons why Microsoft 365 security is essential
According to a recent Cofense report, threat actors exploit Microsoft Office documents with tactics ranging from simple to highly advanced. Common methods include embedding links or QR codes within documents that direct users to malware hosted online. This isn’t just a rising trend; it’s a clear signal that your productivity tools are under constant threat. Let’s look at the top 8 reasons as to why you need to secure your Microsoft 365:
1. Phishing and Ransomware Attacks via Email and Microsoft 365 Collaboration Apps
Microsoft 365 remains a primary target for threat actors, who exploit emails and collaboration apps like Teams to execute attacks. These threats can lead to data theft, operational disruptions, or ransom demands. Safeguarding your organization’s data with strong security protocols minimizes these risks and ensures uninterrupted business operations.
2. Limited Backup Features and Capabilities
Built-in Microsoft 365 options often lack the flexibility needed to meet business requirements. Manual processes and storage limitations can make data management cumbersome, exposing businesses to potential data loss. A more stringent approach ensures quick recovery and smooth operations in critical situations.
3. Dynamic Scanning of All Content
The inability to scan all shared files and links across platforms like Teams, OneDrive, and SharePoint leaves organizations vulnerable. Harmful content can bypass security measures, potentially compromising systems. Comprehensive scanning tools ensure all data is monitored and threats are neutralized before they cause harm.
4. Accidental Data Deletion
Unintended file deletions—whether through user error or routine cleanups—can lead to permanent loss of critical information. Recovery mechanisms help retrieve important data, reducing disruptions and ensuring that mistakes don’t hinder productivity.
5. Malicious Actions
Dissatisfied employees or other internal threats can intentionally delete or tamper with sensitive information. Organizations need vigilant measures to recover affected data and address such incidents without significant downtime or financial loss.
6. Employees Overwriting Data
Errors like overwriting important files or saving incorrect versions can create confusion and delay projects. The ability to access and restore previous versions helps resolve such issues quickly and keeps work on track.
7. Lost or Stolen Devices
With the growing use of personal devices for work, the risk of data exposure from lost or stolen equipment has increased. Ensuring data is securely stored in accessible locations protects sensitive information and maintains operational continuity.
8. Limited Storage and Email Retention
When employees leave, their data can be lost due to retention policies or lack of proper management. This often results in missing important business records. A systematic approach to preserving data ensures that vital information is retained and remains accessible for future needs.
