File security is all about safeguarding your business-critical information from prying eyes by implementing stringent access control measures and flawless permission hygiene. Apart from enabling and monitoring security access controls, decluttering data storage also plays an important role in securing files. Regularly optimize file storage by purging old, stale, and other junk files to focus on business-critical files. Tackle data security threats and storage inefficiencies with periodic reviews and enhancements to your file security strategy.
Personally identifiable information (PII), electronic personal health information (ePHI), confidential contracts, and other business-critical data must be stored safely. Careless transmission or use of such files could lead to data privacy violations, resulting in heavy fines for the organization.
Files transferred through unsecured channels can be misused by insiders or hackers for malicious activities. Comprehensive data leak prevention software can help prevent unauthorized movement of business-critical data out of the organization.
In 2019, personal details of 10.6 million MGM resort guests were breached. The impact of such a breach can be fatal to any organization. It is not just the fines and legal consequences, but also the loss of trust that can destroy a business.
The principle of least privileges (POLP) ensures that only the bare minimum privileges required to complete a task is granted. It is advisable to define access control lists (ACL) for files and folders based on user roles and requirements. Resolve permission hygiene propagation issues like undue privileges, and open access to files with a security permission analyzer.
All file transfers should be authorized and secure. Audit all the possible ways files can be transferred, and block private devices like personal USB drives. Use USB data theft protection software to stop unofficial data transfers.
Be wary of multiple failed accesses, bulk file renames, or modifications. Mass, unofficial file modifications such as delete events may indicate a ransomware attack. Be prepared by automating your incident response against file threats with robust file server auditing software.
Enforce multi-factor authentication (MFA) for all users in your organizations. MFA makes it difficult for hackers to penetrate the network. Authorize only valid and official data access requests. Grant open access to all employees and partners only when necessary.
Analyze and manage your file repositories periodically. Know where your critical files are stored in the organization. Continuous review of stale files and unused files helps eliminate permission misuse incidents. Revoke permissions on files owned by former employees.
