How Good is your Employee Termination Policy?

A former employee of Baltimore Substance Abuse Systems Inc. compromised his boss’ computer during a presentation and replaced some of the content with pornographic material. It is customary to have policies in place that require terminated employees to be escorted out of the building by either a security officer or member of upper level administration.
However, when it comes of terminating employees, this case highlights the importance of having a solid corporate termination policy. The actions of this former employee embarrass the company during a presentation but what if he would have deleted business critical data and trashed the backups? Or copied the business critical data (i.e. financial data, client credit card data or employees’ information) and sold it to the highest bidder?
It is important to have a policy for limiting access to corporate technical resources after an employee has been terminated. Some basic step include: disabling user account(s), changing or locking all the passwords the former employee had access to, disabling corporate e-mail access and locking down access to their personal workstation.
An email from HR using a pre-configured template to all key stakeholders with a mean of reporting back to HR, confirming the work has been completed, would help prevent this kind of malicious activity. Of course, the account(s) should be monitored to detect potential unauthorized access. Do you have similar horror story to share?

Last time I checked, a tech's average stay anywhere is about 18 months. That's why most of us are "Consultants" now.
.
One a persons role within the organisation changes, so should their access levels.
Far too often I've seen people being allowed access to systems that are far out of their current scope after doing a particular job to cover mat(pat)ernal leavers.
I'm calling b.s. on that one.
I hope you at least look the person in the eyes when you do that. You wouldn't happen to be Mr. Burns, would you?
While you seem to take a HUGE amount of physical security in your termination procedures, you let slip that you actually have very poor internal security on the technical side.
If you have to change remote access IDs and passwords, that means you're using some form of shared authentication creds (username & password that more than 1 person has access to). Sure, you might take the required precautions when someone is terminated, but what about when you have a bad actor that is currently employed? They can use the shared authentication to get in & you would have no idea who the bad one is.
Shared authentication should never be used. If there are cases where you need to have a special account as a backup, you have two people form the password in turn, then put the two halves in a sealed envelope that is in secure storage.
Pevensey:No b.s. here whatsoever. Where there is an inventory of 10+million USD of technical parts, you take preventative action to protect that inventory as well as protection of the internal network and other employees. We have never had a problem to date. Would you rather have us terminate the employee and then give them a few hours to get their "things" together? I think not.
The cops will do pretty much anything for anyone that pays them and has some level of standing within a community (small business owner is good enough). The U.S. is quickly gaining 3rd world banana republic status, in case you haven't noticed. Complete with an East German style police state - 50% of the population employed in one way or another (police, medical responders, firemen, postal workers, meter readers, teachers, social workers, children, etc.) to spy on the other 50%, most of whom are unemployed.
I have full "keys" to the city and I was told this past Monday that I am no longer needed after next Friday. Because of my hours I was told prior to any other sysadmins being on site, I was permitted to leave the GMs office and return to work. I would have expeated my accounts to have been locked, and to be escorted out.
Obviously I must have high moral values.
Also, there was another sysadmin told the same thing on Tuesday, he still sits beside me.
Oh I almost forgot to meationed the accounting staff were gased too. They're too still siting at their desk with their usual level of access.
Do you think our employer dropped their pants?
Maybe they don't care as our employer was bought by a larger player.
k.o.
we may want some of these employees back in the future. having too stark a policy can be tough on morale not only for a loyal spontaneously-former employee but for remaining employees.
this needs to be considered all the while making sure transitional security is maintained.
the account lockout process might better be mediated by adding a transitional phase that included a sandbox feature to be accessible until they are 'out the door'. where the exiting employee is allowed to write file final reports, emails and suggestions to an embargoed sandboxed area before they are turned away. the final reports after being vetted can save the remaining employees time and trouble trying to figure out where the former-employee was on various projects as the workload is shifted. the sandbox feature could provide limited access that keeps company systems/data disconnected and safe but lets the employee do some housecleaning tasks they had been working on that they dont just want to dump without pomp. this is not only less traumatic to an employee that was loyal but can also bear on safey and security if for example they had noticed but not yet got to filing reports on a recent packet analysis or failing mixing valve or pressure sensor.
However, you can rent-a-cop for however long you wish, provided it's scheduled. Big events do so all the time - for traffic flow, security, whatever - the event is paying for that detail. Large shopping malls rent cops all the time. Likewise, we rented a sheriff to stake-out our parking lot for a few weeks during overnights... as a cop, to catch somebody.
So, if he's got the budget for it, nothing stops Old Dad from actually having two officers on-site 24/7... but it's not an ad-hoc thing, as some were expecting.
In other news, the most important thing is having a way to quickly disable all access. If everything is tied to Active Directory or a single sign-on solution, that means you disable one account and everything stops.
Most normal terminations where I work rely on a status change being filed in HR and the nightly IAM batch disabling the account.
Emergency status changes for folks to are leaving on bad terms or who have deep admin rights result in emails being sent to the managers of the appropriate groups from Corporate Security and accounts being manually disabled as close to immediately as possible.
There was the time that an employee went to lunch and when she got back her badge didn't work and her boss was waiting in the lobby with a box of her stuff, but that guy was an ass.
NOTHING pisses a worker off more than a sudden, suprise firing.
Your HR might actually like doing it this way. From their point of view and maybe the manager's POV too, it beats a long, drawn-out struggle. But from the worker's perspective, your company just made a new enemy.
Having said that, I did hear of a major bank that wanted to make several employess redundant so they had a fire drill and then only let certain people back in the building. Harsh!
That means that an employer can fire an employee for any reason or no reason at any time with as little notice as they care to give.
But, don't worry, they give the worker the same power to quit at any time for any reason.
Hm.. that does seem a little bit lopsided, but that's the good ol' US for you.
I don't think all states do this, but the last two I've lived in do.
