Security mindsets of MSPs
-
One of the most important documents that any IT pro can know....
-
Law #6: A computer is only as secure as the administrator is trustworthy.
-
I trust them to work on my systems. I don't trust them to prevent credentials from getting into the wrong hands as a result of their sloppy security procedures.
At the moment they can only come in if I let them, by enabling their AD account. The problem is who let's them in when I'm not here. If my colleague does this, how do I make it easy for my colleague? Alternatively, I could enable their accounts before I go on holiday, and disable them when I return.
In the days before remote access, they would have to physically enter the building to do any work. There are checks in place to prevent anyone walking in to the building (ie visitor management & security procedures). How do I replicate the physical management procedures in the on-line world? I need a robust system that balances the risk of unauthorised access versus the risk of downtime as a result of no-one being able to access something that needs fixing.

You can't differentiate. Distill what you wrote to "I don't trust them."
So, you can't use them. That's your answer there.

Yes. Or have management do it. Turn it on but have management hand over the passwords. Or have management enable/disable and nothing else.

Well if the building was locked up and they needed to work.... either....
- Give them a key and they can get in any time or...
- Don't give them a key and trust someone internally with that right to let them in and out.
Technology doesn't change the choices. It might appear to, but it really doesn't.

I don't trust anyone external. But I have to take a holiday.

It doesn't change the choices but it changes the solutions. Creating a procedure that allows a colleague to grant admin privileges to external agents isn't a trivial task.

Them emailing you the passwords, for lack of a better phrase, is pretty derpy. Next go around, set up separate users and passwords for your main systems. That'll give you the ability to block their access as needed without having to hand over your passwords. If you want to get rid of them, toast their accounts. If you go rogue, they can still help your company keep control.
Also, take a look at the other types of companies that the MSP works with. Ones that have more security-focused clients will naturally lean towards being more secure.
-
Also realize that email may not be as insecure as you think.
Before you went off the handle and wasted all that time changing passwords, did you check if the email had been sent via TLS?
-
Went off the handle, LOL. Firstly, I don't consider changing passwords a waste of time. I probably don't change them enough. Secondly, it's the principle of the thing that annoys me. Bad practice is bad practice. I don't keep passwords listed in Word documents. I don't think they should either.

Not very many SMTP servers use TLS by default (even if both sides have it available).

In this type of situation, where do you keep the passwords for all of your different clients for all of their different systems?
Personally I don't mind if they use Word/Excel to store these. The best I can hope for is that they are being stored in a safe manor - i.e. not everyone in their company has access to the files, even better if stored on encrypted drives, etc.

Office 365 does.

This is very interesting to me. As a smaller fish in the IT biz I am trying to do right with security and all of you have a different slant on passwords in emails and in documents. My goal was to password protect my SharePoint OneNote page with my clients User/Pass list. For my web/email hosting clients, I was going to delete all passwords I had on file and require them to create new ones if they forget. I still would have to check how secure my services desks were for sending out passwords for users who request the password reset. Seems like you really can't secure it all, or easily. And how many roadblocks do we want to put in the way of people wanting to get work done?

Then you have a gap. You have to choose. Trust or don't take a holiday.
What makes the external nature of someone seem distrustful to you but not someone internal? It's the same pool if humans.

Business class ones all do. Maybe those insecure "on premise" people have that problem still but it has been gone for the hosted industry for a long time

Depends on a lot if factors. This one no MSP should disclose in too much detail for obvious security reasons.
We can say we do a number of things including varying by client, layers of access control, key based access, access control to lists, etc. We have talked about building a custom break glass style system.
High security passwords are kept in a secure system inside a secure system.
Highest security are "in brain" only with a physical break glass in case of bus scenario.

What do you mean by 'a long time'? Google only went to TLS in light of the revelations of the NSA spying on people. Before that they didn't have TLS enabled by default for SMTP delivery. Hell, they didn't even have encryption between their own datacenters (though.. I will give them a break on that since they believed that those pipes were private and not being spied on through the carrier).

One major thing that we do for. Lot if access is limit normal access to coming in through secure central access point and access is then via a key, rather than a password. It's small but it limits problems while making access easier to win at the security vs. usability war.
