Here で shows the means/source/context used to check something.
So ログイン履歴で不正アクセスを確認する means something like:
- check for unauthorized access using the login history
- confirm unauthorized access from the login history
- look in the login history to verify unauthorized access
It is not the direct object of the verb. The direct object is 不正アクセス.
Because 確認する is being used as a transitive verb here, and を marks what is being checked or confirmed.
So the structure is:
- ログイン履歴で = by means of / in the login history
- 不正アクセスを = unauthorized access as the thing being checked
- 確認する = to confirm / check
In natural English, we often say check the login history for unauthorized access, but Japanese is structured more like confirm unauthorized access by using the login history.
