What is the best way to secure the most vulnerable attack vector for a network?

Choices:

A] Remove unneeded services running on the servers
B] Provide end-user awareness training for office staff
C] Update all antivirus definitions on workstations and servers
D] Use biometrics and SSO for authentication

Hey First Question - Thanks Scott

My first instinct D]Use biometrics and SSO for Authentication

The key words in the question is "most vulnerable attack vector" so IMHO, D] would incorrect.

Well People would be the most vulnerable

so B?

Correct, B. @scottalanmiller will have to confirm though.

I thought that too, but then I thought that was too easy and that he probably was meaning something else .

The test SHOULD be too easy. If you really know the material, and are paying attention to the reading (because the questions are designed to not let you skim them), it should feel pretty obvious a lot of the time.

@brandon220 said in Windows and NFS:

@Pete-S The locking is also what I was referring to. I will most likely set the share up for both and do some testing.

There should be locking from the filesystem so that either Samba or NFS has the file at any given moment. It's the filesystem's job to make sure that two processes can't access any given file at the same time. That the processes are NFS or Samba shouldn't matter. NFS or SMB can have another partial lock on top of that, for sure. But that should be on top of the file level lock.

That is an incorrect assumption. Read this: https://en.wikipedia.org/wiki/File_locking

Which part? I read the part of NFS, but that doesn't seem to apply. That would cause problems, but not corruption problems, right?

Just that comparing windows and *nix you see that there are different file locking mechanisms in play. That is what could cause corruption. Samba has to support Windows mechanisms while it's file system is residing on unix.

For instance from Samba 3.0 documentation (for historical context only):

Record locking semantics under UNIX are very different from record locking under Windows. Versions of Samba before 2.2 have tried to use the native fcntl() UNIX system call to implement proper record locking between different Samba clients. This cannot be fully correct for several reasons. The simplest is that a Windows client is allowed to lock a byte range up to 2^32 or 2^64, depending on the client OS. The UNIX locking only supports byte ranges up to 2^31. So it is not possible to correctly satisfy a lock request above 2^31. There are many more differences, too many to be listed here.

Samba 2.2 and above implement record locking completely independently of the underlying UNIX system. If a byte-range lock that the client requests happens to fall into the range of 0 to 2^31, Samba hands this request down to the UNIX system. No other locks can be seen by UNIX, anyway.

That's very complex. But it sounds like Samba is just... not locking the file and hoping for the best?

I see they have a limit on how many you can buy. Ugh!

Geez, how many do you need? If this is for corporate, I'm sure there are other options that don't have those limits.

Sure. Although weird to have come back after five and a half years just to close the account. It's been abandoned for most of a decade already.

Here one that might perk your interest:

I will never buy Lenovo. I did not like them before they got caught stealing info.

ALso, tha tis Windows 10 S mode. No thanks.

Wait - stealing info? I don't know about that one.

I know about Superfish - installed shim in network stack you couldn't get rid of to allow advertisers, etc access into encrypted transmissions
and the BIOS thing would would reinstall the Lenovo tools under windows...

That's what Superfish does, sends data back to a Lenovo "partner" company. They can steal any data they want, and you can do nothing about it.

OH I didn't realize it was actually sending data back to partners.. I thought it's general purpose was to insert ads... of course, it could do any damned thing it wanted....

Right, exactly, it was an unlimited capability device. It could inject or retrieve data in either direction. In order to inject, it would have to send back first.

It's been going on for a while. It might all be one organization, but it really does feel like multiple. But I suppose, good spam will feel that way.

@Dashrender said in Covid: Antibodies 'fall rapidly after infection':

I have no idea what we are talking about anymore 😉

Kung Flu or Corona Virus or the astronomical costs of health related stuff... Or some combination there of.

OH is that all? we're all fooked - that's all I know.

my own opinion that no one has asked for or cares about -
The pandemic will end (end-ish) when those with co-morbidities get it and die off. Those left behind will get Covid again and again just like people get a cold or flu again and again.

I have zero expectation that a vaccine will wipe this thing out...

That said - I'll be happily wrong if we instead end up like measles and the vaccine does prevent the disease... but I certainly don't expect that to the be the case.

So with my opinion being what is it - how long do we keep things locked down, destroying the economy, etc?

Why did they take this name away?

Their policy is that they never tell you why. They only tell you that their policy is to not inform you.

yep, it works for concatenating the files quite well. just fiddling around with it now.

We don't ever overcome it. We just search for tools to better list it(documentation) so we can always see how much we will never finish 😖

How did you end up liking this system?

I liked it well enough- until there was issues with the battery. Which caused all sorts of issues.

I ended up selling it on eBay and taking a bath on it.

Great idea, just not as well implemented.

It's a French origin, but so is resume. It's a word in English for a very long time.

all true but maybe they have a cutoff somewhere before it is recognized. I am just guessing though.

@scottalanmiller I saw some job postings from Basecamp the fitness company be linked to Basecamp the tech company. They're probably trying to autolink stuff together and royally screwing it up.

Business Consultant and Entrepeneur

I've worked in loads of different roles and industries. I find that as IT is just the infrastructure component of business, and that separating the two is nearly impossible, that over the years I've moved from being an IT generalist to a business generalist and now tackle IT from above, dealing as much with the overarching business concerns as the IT ones.
