Training Steps

Introduction

Welcome to Nexlify Solutions! You are Alice, a project manager responsible for coordinating development projects and client communications. Today, you will learn about data leakage risks and how sensitive information can be accidentally exposed through everyday business activities.
Preparing for Client Meeting

Alice is preparing for an important client call about Nexlify Solutions' new software product. She needs to access the client database using her account credentials. As she prepares, Alice writes down her account password on the whiteboard because it's been updated recently and she's not used to her new password yet. The password is now clearly visible on the whiteboard behind her desk, but Alice is not aware of that.
Accessing Client Database

Alice needs to access the company's client database to prepare for the presentation. She uses the web browser to open Nexlify Solutions' internal client database portal and signs into her account using the password she wrote on the whiteboard. This database contains sensitive client information that will be referenced during the upcoming meeting.
Receiving Meeting Invitation

Alice receives a meeting notification for the client presentation from what appears to be GlobalTech Solutions, a legitimate prospective client. However, one of the participants 'Bob Stevens' is actually a corporate spy from CompetitorCorp using a fake identity.
Joining the Video Call

Alice joins the video meeting with GlobalTech Solutions. She positions herself at her desk with the whiteboard clearly visible behind her. Bob Stevens, the corporate spy, immediately notices the exposed password and discreetly records it.
Successful Meeting Conclusion

The meeting concludes with what appears to be positive results. Bob Stevens expresses particular interest in how client data is stored. Alice finds this question slightly unusual but confirms they have a secure database. Overall, Alice believes the meeting was successful.
Bob's Corporate Espionage

After the meeting, Bob uses Alice's password to gain unauthorized access to Nexlify Solutions' client database. He downloads the complete client database and sells this competitive intelligence to CompetitorCorp.
Devastating Contract Loss

The next day, Alice receives a shocking email from GlobalTech Solutions informing her that they have awarded their contract to CompetitorCorp instead. The competitor somehow offered terms and pricing that exactly matched GlobalTech's specific requirements.
Security Breach Discovery

Later that day, Alice receives an urgent email from Nexlify Solutions' CEO and IT security team. They have discovered during a routine security audit that the company's client database has been compromised.
Devastating Realization

Alice suddenly turns around and looks at her whiteboard, realizing with horror that she caused the security breach. Her password was visible behind her during the entire video call, allowing Bob to access the client database using her credentials.
