It's really hard to say as there's very little information present, and the answer depends very much on what software (and version) is being run, as well as what your applications are doing. Can you provide some additional context?
Suggested information:
- Product being used and it's version
- What is your application? Is it commercial/off-the-shelf or home written? What language & framework is it using?
- Are there any particular CVE's or vulnerabilities (such as might come up with scanning software or through OSWAP top-10 list) that are triggering this query?
Thanks
