@scottalanmiller said in Make Simple User Passwords:

Ever need to make passwords for users and, let's face it, in the real world a lot of customers demand some pretty silly simply passwords. Using password generators often results in passwords that customers will not (and maybe cannot) use. A ridiculous situation, obviously, but it is reality. Passwords are simply difficult to often pass on to someone.

When generating temporary passwords, having something super strong is rarely very important. But avoiding something too hard to be used is needed. But just making up something non-random or even non-unique is really bad.

What's a compromise?

Yup, here is reality. Sometimes children's tools just make more sense when, well, you can draw your own conclusions.

but how do you use a YubiKey on your phone?

Screenshot from 2019-03-05 10-05-44.png

That's exactly how I do it. You can also use the Yubiauth app on both the phone and Windows to hold OTP codes for stuff that doesn't support u2f.

So there's a way to export the private key out of the YubiKey? or the sites allows for multiple public keys?

Huh? You scan the QR code like you normally would but it stores it on the Yubikey instead. Then when you need the code you either tap it to your phone and it shows you all of the one time codes or you do it on your computer. Just like how Google authenticator works. For the u2f stuff, it works the same on Android as on your pc. The browser needs to support u2f and it does the challenge response.

I've never used a YubiKey - I assumed the private code inside the YubiKey was there and no where else.

It depends on the type of authentication.

you can set static entries in EdgeOS.

Always set DHCP to give out the ERL for DNS. set service dhcp-server shared-network-name LAN subnet 10.254.103.0/24 dns-server 10.254.103.1 Always set the ERL to look at itself for a DNS (127.0.0.1 set system name-server 127.0.0.1 Make sure that DNS is listening on your LAN ports. set service dns forwarding listen-on eth1 set service dns forwarding listen-on eth1.2 Set DNS forward lookup to whatever. set service dns forwarding name-server 10.254.103.4 # my Pi-Hole set service dns forwarding name-server 1.1.1.1 If oyu are on a domain, tell EdgeOS to forward those to the DC. set service dns forwarding options server=/ad.domain.com/10.254.0.21 set service dns forwarding options server=/domain.local/10.254.0.21 set service dns forwarding options server=/domain/10.254.0.21 Set up your static DNS entries. set system static-host-mapping host-name nas inet 10.254.103.7

The first time it is used, we have to manually type the domain\localadmin password.

Sucks when a site / business like that gets hit. Just people looking to have fun 😞

Yeah. But at least they didn't store the passwords in clear text!

Another day, another security breach/problem.
Note to myself: Am I getting used to that?

@pmoncho said in Kerio Connect "license error: license exhausted, cannot allow another host":

Based on the couple posts I have seen, each registered user can have five devices. So, if they have 30 devices, they need 6 user licenses. Did they add any extra devices lately?

Easily, but more likely they just let their license expire.

@stacksofplates said in Researchers use Intel SGX to put malware beyond the reach of antivirus software:

Did you see what Intel said regarding this:

Intel is aware of this research which is based upon assumptions that are outside the threat model for Intel SGX. The value of Intel SGX is to execute code in a protected enclave; however, Intel SGX does not guarantee that the code executed in the enclave is from a trusted source. In all cases, we recommend utilizing programs, files, apps, and plugins from trusted sources. Protecting customers continues to be a critical priority for us and we would like to thank Michael Schwarz, Samuel Weiser, and Daniel Grus for their ongoing research and for working with Intel on coordinated vulnerability disclosure.

Outside of the threat model?.........

Haha, whatever that means.

Just used this again today, as another script I have had this attribute.

Not sure when the attribute was written to the script though. But it's working now.

This is the full error.

All it takes is one absentminded click or drive-by that's completely shielded from us as we go about the day to day stuff and it's done. Game over. Say, "Bubbye".

There's always going to be that risk or one absentminded click.

Granted an Air-gapped PWA is a good way to handle it.... but so is not saving passwords in RDP files (I don't do this), and if you use an app like MobaXterm that can encrypt the files for you, use a good pass phrase.

However if your admin machine is owned, you have bigger issues to start with.

Well, the idea is that the air-gapped machine won't ever be in a situation to become compromised, is my guess. I haven't had a chance to look at the MS link Philip sent earlier.

There are several ways to implement with the simplest being the main machine having two VMs installed on it. One for day-to-day and one for client/systems management. Nothing is done on the machine itself with all designated tasks being done in their respective VM.

We have a number of laptops that came back from client refreshes. So, we're using them as our dedicated management machines. Asus makes a great external USB3 DisplayLink and DisplayPort external monitor that allows for two screens. That makes the work easier.

There is security leakage between VMs on a client machine for instance over clipboard.

Have a look at Qubes. https://www.qubes-os.org/

It's probably the best implementation of security separation to date.

Using the Hyper-V VM Console without RDS pass-through eliminates any access to the VM beyond console.

Same with KVM or whatever.

MSP Maturity Model. Strictly speaking, the MSPMM does not tell MSPs to make all of their customers identical. But in practice, it encourages it and many MSPs talk about the MSPMM in these terms - finding ways to make customers all run the same tools, software, practices, network design, etc. This makes management so much easier for the MSP, but has two major problems.

First, it forces the customer to conform to the vendor, which makes very little sense. IT needs to adapt to the business, not the business to IT. But that's another topic.

Secondary, it means that an attack vector that works on the MSP will likely work on every single one of their customers making the prospect of breaching the MSP that much better. Sure, if a targeted attack by experienced state-sponsored hackers goes after an MSP, the MSP has little chance of winning that battle. But that isn't the real risk. In the real world, the risk is automated attacks looking for common vulnerabilities and spreading organically through shared tooling - things that are only possible or reasonably likely when the environments are homogeneous: both amongst the MSP clients, and between clients and the MSP themselves.

The traditional approach of MSPs, especially VAR - MSP combo companies, is to have not only the same tools and software, but even the same hardware and products so that any hole anywhere because a hole everywhere and breaching any one piece of the infrastructure means you are likely to breach it all.

https://arstech.net/zimbra-fail2ban-setup/

I came across that article and it's the most promising. Though it's still a iptables based fail2ban configuration. I'm not sure if it's as simple as changing the references to iptables or if tweaking it to work with firewalld is more involved.

I suppose an option is to disable firewalld and install iptables. I've done that before in the past.

Hmm...

That's probably what they did, because you need to disable firewalld to enable iptables.

In the event now.

Anyway, in the case of the CPA we are talking about material that is not really sensitive at all.

The data files could be secured the same way as any paper records. Locked in a safe when not in use.

That would be the same as being encrypted, since the lock on a safe = encryption and the physical key = the passphrase to decrypt the drive or data.

Well, in principle only. You can walk away with the encrypted computer but it would be harder with the safe.

In most cases physical security is about delaying. You can smash and grab a laptop from the office window but it would require a lot more time to break in properly and then open a safe before someone shows up.

You have those examples a bit mixed up.

The comparable scenario would be "getting to the data" The physical medium housing that data doesn't matter.

You break the lock, you get the data. If you break the encryption key you get the data.

But a physical lock is likely easier to break and get into whatever than it would to decrypt a encrypted volume.

There are so many real surveillance cameras for little money that are made for the purpose already. For instance this outdoor model for less than $30:

To get real coverage you need different lenses in different applications and indoor and outdoor options as well. Installing cameras, wiring it all up and installing software and having storage, backups etc and keeping everything running is too much work to save a few bucks.

The hikvision cameras apparently are utter crap and worth avoiding.
