A friend of mine who is a night owl mentioned she frequently has to stop working because her company's VPN shuts down at a certain time every night and comes back on in the morning. She was told this is for "security reasons".

I have worked in many companies with VPN access and have never encountered this. It seems like a highly questionable practice since it is clearly having a negative business impact and I can't see how it would add any significant security value.

Is this practice respected in the industry?

  • Its highly questionable to log into your company's network at 2:00 AM, and after hours activity is a huge red flag

  • Really? I do that on a regular basis. What is highly questionable about it? People are free to work at any time. I'm a software developer and have often worked during the night and evening, for decades, especially from home.

I have encountered and even configured this. The idea is to reduce the attack surface by only allowing remote access during the time when remote access is expected.

Your friend is doing something unexpected. And that's OK. The security people should account for and support this (if it is in line with business need - your friend might actually be violating a specific work policy, too, or not, but I've seen business policies like this for various reasons).

So, yes, this time restriction is normal and it is for legitimate security reasons. But that doesn't necessarily mean that your friend cannot also get a security exception so she can do her work.

    I did a project on a company that LOCKED the computer even if you were working during certain times, and locked your account in the domain so you could not unlock it again and could not log anywhere.

  • I wonder if banks leave their front door unlocked after hours....

  • @john doe, Except they do. You can do online banking 24/7. Most ATMs are also 24/7
