Who accessed a particular file share, and what changes happened? If you’re not able to answer this question quickly, you’re not alone. Monitoring file changes is one of the simplest tasks in keeping sensitive data safe but also one of the most neglected areas in many environments. FileAudit addresses this weakness with an easy-to-use reporting and alerting tool.
Pinpoint the access to and usage of Windows File Shares
There are several best practice techniques on the security of Windows file sharing but when it comes to monitoring and auditing for access and changes, Windows operating system’s native tools are inefficient and don’t scale well.
It isn’t much fun having to review audit entries in the Windows Server Security Log on each file server. To find out something as simple as “Who accessed your protected files today and what changes happened?” requires much more work than just skimming through the event log data. It requires meticulous research into specific field values within multiple log entries, all to “puzzle piece” your way to a potential answer.
FileAudit allows administrators to pinpoint access and monitor changes to selected files.
Monitor file and folder changes in real-time
FileAudit offers real trace-ability of changes made. It monitors your file system resources continuously to instantly provide accurate and comprehensive information about access events and access attempts.
By tracking the User, IP Address and Machine Name, you know exactly who changed what and where the change took place, including events made remotely.
Save hours of time-consuming research
Find out the answers you need on certain activity with far less effort. Numerous filters mean you can zoom in and focus only on the information you need.
Tip: If you’re looking at just recent activity – from the last 4 weeks – click on any user, file or folder and you get a detailed insight into the access and usage of that particular data set.
- View the frequency and amount of activity
- See the total number of file deletions and refused access events
- Scroll through a listing of all changes performed for a specific user (or file or folder)
Alert on abnormal file activity
Administrators can set customized alerts in real time, on any type of access event (or access attempts).
Some of the unusual activity you should be looking for include:
- Access from a particular IP address or an endpoint outside the company network, or one that doesn’t normally access a given set of files can be a clear sign of improper use.
- Alerts on bulk file copying and mass file deletion or movement from the Windows File Server is excellent for highlighting suspicious user activity and data ex-filtration during a breach.
- Alerts on changes made at suspicious times is another common sign of potentially malicious activity.
- An attempt to access files without permissions.
Get full visibility across all your shared files
FileAudit consolidates access events from multiple servers. Complete visibility in what’s going on across your organization helps you gain precise answers to question such as “What files did John Smith change last week?”
Delegate monitoring to improve file security
FileAudit embraces a role-based access control (RBAC) model in which you can delegate sub-administrative access to the FileAudit management console.
The reality is, those closest to the files have a much better sense of whether someone’s access – or use of permissions – is proper. By utilizing users closest to a set of files and providing them a way to quickly review and identify inappropriate activity, IT improves its both their own productivity and the organizations’ security.
Improve the security of your shared files
It’s critical to monitor all changes to sensitive data. Not only unauthorized access but authorized as well.
- Firstly, whatever your industry, your servers remain the primary asset of choice for attacks. Files can contain valuable data such as PII (personally identifiable information), PHI (protected health information), or of course – financial card data.
- The second, and somewhat forgotten, is the manipulation of Operating System files and file systems to provide access to a given endpoint. Malware used to gain initial access to an endpoint often places (and, in some cases, replaces) files that are called upon bootup to maintain persistence. Additionally, certain techniques that involve the copying, replacing, and renaming of files are used to provide access to additional endpoints to facilitate lateral movement within your network.
- You should have a way to detect massive file encryption on your file servers. The sooner you detect a ransomware attack the sooner you will be able to stop it, which means less data loss and less work to clear up the mess!
- Mitigate the risk of shared files being tampered with or altered in any unwanted way. Examples include overcoming the risk of tampered files being unsuitable for use in court and stopping incidents of intellectual property being falsified or even deleted.
- If a file is deleted or changed, users tend to blame ‘the server’ or the ‘IT Team’ for losing their work. A full audited history of all changes helps resolve the matter, quickly!
- Monitoring the access to and usage of protected data demonstrates only approved access has occurred – critical to meeting relevant compliance objectives.
Trial FileAudit now
Inappropriate access or changes to files and folders, whether intentional or not, could put an organization at risk of data loss, a security breach and non-compliance. FileAudit provides the centralized monitoring and analysis of file activity necessary to better secure your organization’s data.
