Digital Forensic Discussion: So You Fired An Associate
Every company at every level has had to perform the unenviable task of forcefully off-boarding an associate or employee. Usually, this is initiated by management and executed by Human Resources. Somewhere in this process, the associate is informed of the decision, sometimes placed on suspension pending adjudication and often terminated when the final decision is made. It is at that point when company property, such as computers and cell phones, is often collected from the newly-former employee and generally recycled to be used by a successor or other company representative.
Terminations can be executed for a variety of reasons. Violations of non-compete clauses, intellectual property theft, gross violation of company policy or breach of contract are just a few reasons why a company may decide they no longer need the services of an associate. However, several crucial elements should enter into this timeline of events, particularly surrounding the collection, preservation and use of company electronic devices.
Timing is Crucial
When an internal investigation is conducted, corporate and/or H.R. representatives often don’t have the luxury of acquiring the company’s assigned digital devices as part of the investigation prior to suspension or termination. This makes the timing of collection of these items crucial. If you wait too long, valuable information could be destroyed. If you collect too soon, the subject of the inquiry could be tipped off about what is going on and that could jeopardize the integrity of the investigation. So when should you acquire the company’s digital assets for analysis? We suggest doing it at the time the target of the investigation is made aware that they are being investigated, which is generally at the time of initial suspension. Unless union or other policy dictates targets be made aware of the investigation as soon as it is initiated, there is no better time than notification to the target that you have compiled enough information to act upon to seize the digital devices.
After the devices have been collected, they should be locked away in a safe place with limited access until a digital forensic expert — not information technology staff — can be called, consulted and respond as appropriate. Cell phones should be placed in airplane mode and disconnected from all networks immediately. The question has been asked, why not use IT staff, they know all about the computers, right? Suppose the person whom you have been investigating and are potentially going to terminate works in the IT department. You would then be putting their friends and/or co-workers in a difficult position taking part in an investigation against their soon-to-be-former co-worker. Beyond that, most IT staff do not have the requisite training and experience in forensic data acquisition and analysis. It is analogous to consulting a general practice urgent care doctor to treat your cancer. A specialist is recommended always for best results.
What Does the Forensicator Need to Know?
Digital forensic investigation and analysis is not unlike standard types of investigation in that we need to know the facts. Helpful information such as:
- Who is the target of the investigation and were they the only ones with access to the device(s)?
- What devices are relevant and what data might we be looking for?
- Where have the devices been in use before they were re-possessed and where have they been since
- When is the time frame of any suspected/alleged malfeasance
- How did they access the data on the devices? Passcodes to mobile devices and passwords for any encrypted hard drives and/or mobile devices are very important
- Why do you think evidence exists to support the allegation?
Whenever possible, human resources, management and IT staff should refrain from “fishing” through devices to find evidence to support the investigation. It’s understandable that investigations like this can sometimes be salacious and everyone is curious to find out what was going on, but this violates the integrity of the evidence and opens the door to claims of unfair treatment in its various forms as the case progresses.
Information is important for a few different reasons. First, detailed information helps us develop a strategy for the analysis that will best serve finding the truth in the case. Second, it helps us whittle down the facts of the case and only spend time looking for what is relevant. Finally, providing your digital forensic consultant detailed information will save the company money and time in the long run.
Why is All of This Necessary?
Why do you need to keep appropriate timing & collection of company devices always in mind? Why do you need to call an outside forensic consultant to conduct the analysis & forensic investigation? Because in our litigious society, when someone is terminated from a company – be it a large, medium or small company – it is the corporation’s responsibility to prepare for the worst and hope for the best. By that we mean, always approach the case as if it will go to litigation. Litigation will require discovery, production of documentation, depositions and yes, forensic data analysis in a legally defensible manner. You cannot assume the terminated associate will simply find a new job and go away. Even if they find a new job, there is no guarantee they won’t file suit. Always remember, anyone can sue anyone else for anything. It’s the American way. So as remaining corporate representatives, it is your responsibility to prepare for the eventuality that you’ll have to defend the company’s position. The data on the corporate digital devices doesn’t lie, so what better position to be in as a company than to have the digital forensic ace-in-the-hole when and if the case comes to litigation?
