Monitor suspicious activity in your OCaml application

When building a OCaml application that you plan to release to the public, or even if you're building a private application, as developers, we are always looking for ways to make sure that our application is secure and that it's not being misused.

The misuse of our application can be in the form of a user trying to access data they shouldn't have access to or a user trying to perform an action they shouldn't be able to achieve. This can be a severe problem and can lead to many issues such as data loss, data corruption, or even data theft.

Thus, it's essential to set up a system to monitor suspicious activity in your OCaml application properly and let you and your team know when something is wrong.

For example, let's say you're building a OCaml application that allows users to upload files. One of the common concerns with this type of application is that users may try to take advantage of your service and upload files that they shouldn't be able to upload, such as illegal content, huge files, or even malware.

LogSnag is an excellent tool for this problem as it trivializes tracking events in your OCaml application and suspicious monitoring activity. For example, you can use LogSnag to track an event when a user uploads a file. You can then set up a rule to notify you when a user uploads a file that is larger than 100MB. This way, you will know when a user is trying to upload a too large file, and you can take further action if needed.

Using OCaml with Cohttp

open Lwt
open Cohttp
open Cohttp_lwt_unix

let postData = ref "{\"project\":\"my-saas\",\"channel\":\"monitoring\",\"event\":\"Suspicious File Detected\",\"description\":\"User uploaded a suspicious file\",\"icon\":\"🛸\",\"notify\":true}";;

let reqBody = 
  let uri = Uri.of_string "https://api.logsnag.com/v1/log" in
  let headers = Header.init ()
    |> fun h -> Header.add h "Content-Type" "application/json"
    |> fun h -> Header.add h "Authorization" "Bearer YOUR_API_TOKEN"
  in
  let body = Cohttp_lwt.Body.of_string !postData in

  Client.call ~headers ~body `POST uri >>= fun (_resp, body) ->
  body |> Cohttp_lwt.Body.to_string >|= fun body -> body

let () =
  let respBody = Lwt_main.run reqBody in
  print_endline (respBody)

OCaml integration details

LogSnag is a flexible and easy-to-use event tracking service that can monitor suspicious activity in your OCaml application. It works excellent with OCaml and provides powerful features such as real-time event tracking, cross-platform push notifications, event filtering, user and product journeys, charts and analytics, and much more.

For example, LogSnag automatically generates user journeys for your product, and you can use this to see how your users use your application. In addition, in the case of suspicious activity, you can view the user's journey to see if they have performed any other questionable actions that they shouldn't have performed.

Here at LogSnag, we believe event tracking should be simple and accessible to every developer and team. Therefore, we have worked hard to create the next generation of event tracking tools.

LogSnag provides a generous free plan to get you started with event tracking. You can also check out our pricing page to see our paid plans. So please give us a try and let us know what you think!
