Configure Two Ironport C Series Devices Where the Backup Hosts the Quarantine

These steps come straight from Cisco and it works like a charm.  This allows the primary device to focus on email filtering and the second device to take care of the quarantine work.  I have another post on how to sync the SLBL on these two devices since users will be getting their information from the backup IronPort.

Enable Two step verification for your Naver account

Today Ill walk you through a brief tour of enabling two-step protection on your Naver account.

Two-step verification, or Two-factor authentication (i.e. getting a code on your phone to sign-in), adds an important layer of security to your account. I have this set-up on my Google account. I didnt notice this until recently, but Naver (???) also lets you enable this security feature, though they refer to it as OTP. With all the hacking stories out there, its useful to "set it and forget it." Its pretty simple if youre already familiar with 2-step authentication, with one main difference: the Naver app itself is used for generating the codes. But well get to that.

Creating a Naver Account
The brilliant thing is that 90% of all this process can be done in English. Creating a Naver account and editing all major account settings on Naver can all be done in English (and Chinese), even though most Naver function beyond that are only in Korean. No Alien ID Numbers (??? ?? ??) or passport numbers are needed; but you will need a mobile phone to receive a verification code. I was required to enter a Korean (+82 prefix) phone number, but when signing-up from abroad, you can choose from an international country drop-down list.

Enabling the Protection
Once youve created your Naver account (and it really is super simple), we can enable the Two-step verification.

While logged in, click ??? ("My Account") circled above.
From there, all your settings will be in English. Click over to the "Security" tab and scroll down to "OTP Sign-in (2-step Verification)". You might also want to take this opportunity to enable some of the other security features on this page.


The process is pretty straight-forward. Youll be taken first to an introductory information page.


The main difference between Navers OTP and that of other services (like Googles) is that the codes will be generated within the Naver App itself, not using a seperate stand-alone app (like Google Authenticator) nor by SMS text messages. That last fact is strange, considering that Naver will use an SMS message code to verify your phone number here. Why not just have an SMS option for receiving codes?

Part of the reason may be this:

Note also here that the phone number you use here does not have to be the same number associated with your account (the number you gave when signing-up with Naver). For example, I didnt want to install the bloated Naver app, so here I used the number of a family member who does have the app. It worked just fine, though of course Ill need that persons phone when logging-in on an unknown/untrusted computer. Input the number, Naver will send you an SMS code, and input that code here.


Now it will tell you to install the Naver app (Android - iOS) to your phone, if you havent done so already.
Now its time to get the code from the app and input it here. For this step, youll need to put both the one-time code, and the apps serial number. In the future, youll only need the one-time code.

If youre not sure where to get this code, Ill show you now.


 Open the Naver app on your phone, tap the three-line "hamburger menu", and go down to ? ?? ("App Settings").


Tap the second item "??? OTP".


Here is your OTP code. You can do this each time you want to log-in to Naver on a new/untrusted computer.

Now back to the set-up:


Assuming you input the code correctly, youll reach a penultimate page asking you to choose a back-up email address.


And finally, take a look at the number and email to make sure everything looks good. If youre ready, click "Confirm" and youll now be required to enter the code when logging in.


This is the screen youll be presented with, from now on, after entering you Naver ID and password.
This could be really annoying to do every single time, so dont be a chump. If youre on your personal computer, just be sure to click the "Stay OTP Signed in" checkmark button before entering the code, and you wont need codes for that computer anymore. Set it, and forget it. Enjoy the peace of mind of knowing that no other computer will be able to log-in as you.

Hopefully you found this guide helpful. Though, of course, nearly the entire process was in English so really such a guide is a bit unnecessary. Personally, that makes me glad, that Naver expands their English offerings. Navers services really are useful and powerful; not just "Korean Google". I think they could see a lot of expansion and growth by supporting even just a few foreign languages (English / Chinese / Japanese). As I wrote before, Naver Dictionary and Naver Translate can be used fully in English. Lets hope more Naver services continue to become multi-lingual.
