7 Data Loss Prevention Best Practices
1. How Accidental Deletions Happen
Accidental deletions are one of the main reasons for cloud data loss, often happening during everyday tasks and disrupting business operations.
What Leads to Accidental Deletions
Cloud platforms are particularly prone to accidental deletions because of shared access and interconnected systems. The most common triggers include human mistakes, poorly configured automation, and overly broad user permissions.
- Human Mistakes: When users juggle multiple tasks or have wide-ranging access, they can unintentionally delete important data.
- Automation Errors: Misconfigured scripts, like cleanup tools targeting the wrong paths, can erase vital information instead of temporary files.
- Access Management Problems: Giving users more permissions than necessary increases risks. In fact, 61% of breaches analyzed are linked to identity access management (IAM) flaws.
How to Reduce Accidental Deletions
You can lower the chances of accidental deletions by using strategies like these:
| Prevention Method | How It Works | Benefits |
|---|---|---|
| Version Control | Turn on versioning for key data | Makes it possible to recover earlier versions |
| Role-Based Access | Use strict RBAC policies | Limits who can delete data |
| Automated Backups | Set up regular backups | Provides a safety net for recovery |
Other helpful measures include adding confirmation prompts for important deletions, enabling recycle bins with defined retention periods, and using audit logs to monitor deletion activities.
Regular employee training is also crucial. Teach your team to follow proper data management practices and understand the consequences of their actions. For highly sensitive systems, consider requiring dual approvals before deletion tasks are carried out.
While accidental deletions are often caused by internal errors, external threats like cyberattacks can also endanger cloud data.
2. Protecting Against Cyberattacks
Cloud environments are increasingly targeted by sophisticated cyberattacks, which can lead to severe data loss. To keep your data safe, it’s important to understand these threats and take strong protective measures.
Common Cyberattack Techniques
Identity-based attacks are among the most frequent, with 61% of analyzed breaches linked to identity access management (IAM) vulnerabilities.
Here are three primary ways attackers target cloud environments:
| Attack Type | Impact |
|---|---|
| Phishing | Steals credentials through fake emails |
