Re: guest wireless zone
@Joe

Trust is not an absolute - there are levels.

I trust friends to come into my house, but only a few would I trust to be in the house without a family member present, and others I only trust enough to allow them in if I am there. In the same way, I trust them to access the internet from my home, but I think of it as a matter of least privilege. Why give them more access than they need? Why give them access to other devices present on my network if I can easily create a guest network.

Re: guest wireless zone
@Meleon: Okay, that's certainly a more palatable proposition, security-wise, but wait a minute.

Do you trust your friends and their kids?

Then why have a guest Wi-Fi at all?  Why not just give them the password for your "main" Wi-Fi?

After all, you trust them, right?

Because if you don't, then it would be poor practice to give them access of any kind at all.

Now don't get me wrong.  I'm not saying you're somehow wrong to let your friends and their kids use your Wi-Fi.  I'm just suggesting that a guest network probably doesn't really do much for you when you're talking about a personal home connection.  It's probably just as simple as this: either give 'em the router password or don't, and don't worry about guest networks.

That said: In an enterprise/business/institutional environment, sure.  Go to town with guest networks and segregated WiFi logins.  But it's probably unnecessary cybersecurity theatre in the home environment.

Re: guest wireless zone
@Joe

yeah, I didn't define my scenario well enough. I agree not to set a network without a password. This would be a separate SSID with password. It would be segmented from the home network. So when my kids' friends are over and ask to use the wireless, I can give them the latest guest password

Re: guest wireless zone
@Alex: Respectfully, I disagree with this notion.  I just wouldn't let guests use my Wi-Fi period.

if you have a non-private, password-less zone/network, then bad guys can use it too.

Then you're getting woken up at 5am as armed federal agents bust down your door and raid your house because some pervert in a van parked outside one day used your guest network to access illegal material.

Also, to use a less extreme example, your Torrenting-freak neighbor could easily access such a network to mass-download large media files -- causing bandwidth issues on your own router and modem as you try to do basic things.

And so on and so forth.

Just say no to password-less networks.

guest wireless zone
Create a guest wireless zone which only has access to the internet. So when your kids or guests come over they can get on your guest wireless but not have access to your private network

Home Network Security
Don't forget there are new devices coming to the market that help home network security. A few companies that have these appliances are Bitdefender with Box, and soon Norton with Core. In addition, a few companies have AiProtection from Trend Micro built into the home router solutions.  Adding these devices to your network can help protect all the devices that are connected to your home network.  This ultimately would help solve a lot of the issues that people have when trying to keep their home network secure.

CVE-2020-15208
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a `DCHECK` which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can ...
CVE-2020-15209
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a `nullptr` buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one....
CVE-2020-15210
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b and ...
CVE-2020-15211
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices f...
CVE-2020-15212
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor. Users having access to `segment_ids_data` can alter `output_index` and then write to outside of `outpu...
