I wrote this because I didn't see a good guide that explained the thought process that goes into choosing a cipher suite, so sysadmins could design the right cipher suite for themselves and not just copy a configuration from elsewhere.
Obviously it makes the most sense for companies with "G Suite" as employees can then use gCal to book conference rooms, set up Hangouts video chats in the rooms, etc.
And Google's product costs one-tenth as much. I know there's no way I'd get a budget to spend $7k/room at my company, given we only spend $500/room for furniture the last time we redid them.
Having an ok experience with them at my company. Occasionally one needs reimaging but overall I forget they are there.
I'm not sure what the backup situation is with Android.
I've started backing up the actual strings that the app uses to generate the codes in an encrypted vault. You usually have to manually have these strings shown to you in lieu of a QR code. While creating another avenue for someone to hack you, at least I have a backup as well as a way to add a second device go show me codes. This is definitely beyond the capacity of the average user.
I think there might be online services that handle keeping codes for you? Like you can install an app on your phone, log into an account, and it presents you with all of your codes. Anyone have a recommendation for one of these that works well for them?
What they HAVEN'T enabled is Diffie-Hellman Ephemeral suites, which give older clients forward secrecy at a big CPU hit.
So this is an example of performance-tuning your TLS settings. There's also stuff to do with session tickets, session resumption, and eventually they'd also be served using ECDSA certs, once all clients support it, or there is at least a great way to only show the older RSA cert to old clients.
Usually one of the first things I do when I set up a new router is generate two random numbers between 0-254 (say, 218 and 133) and make the local subnet:
10.218.133.0/24
I frequently VPN to other private networks, and when the local/remote address spaces overlap, like when both are 192.168.1.1/24, then the VPN has problems.
For one, the cloud version doesn't support LDAP or any other directory schemes for controlling user accounts. That's a big deal for companies who have gotten big enough to start using directory to control access to everything, which is hopefully every company with over 100 employees.
Well, not entirely; there are market niches that Let's Encrypt doesn't cover: org-validated and extended validation certs, wildcard certs, anyone who needs a cert that expires in years, ECDSA certs (for the time being)...
But theres no doubt that their revenue will be significantly cut, they'll lose shareholder value and need layoffs.
Their industry did it to themselves; a TLS cert company should have 5 engineers, 5 customer support people, and 2 managers, and should charge about 10% of what they do.
_domainkey.yoursite.com TXT "t=y; o=~;"
Does anyone know how necessary this entry is, as opposed to just having records beginning with selectors?It seems like the t=y means that testing is on and to not actually block messages that fail DKIM, and o=~ means that some messages aren't signed. I'm not sure why the article is suggesting people use those settings, since they are entirely variable between different users and their config.
