How to use your iPad securely

Because there are currently no known remote attacks against iPads, the biggest security risk is physically losing the device. Thus, the first step is to make sure your tablet’s data is safe in case it’s lost or stolen. For that, I’d suggest a combination of encryption and remote wiping.

All iPads ship with powerful hardware encryption built-in, but you need to enable it. The simplest way to do that is to set a passcode on your iPad: As soon as you do, your data will be automatically encrypted. To enable a passcode, go to Settings -> General -> Passcode Lock and then enter a four-digit code twice. If you’d like to be extra-safe, you can turn the Simple Passcode option on that same page off; you can then use longer codes. While you’re there, you should also set Require Passcode for no more than 15 minutes and turn Erase Data on. (Technically, the iPad deletes your encryption key, not the actual data, but that’s faster and just as effective.)

All modern iOS devices also come with a second layer of encryption, called Data Protection. While the basic encryption enabled by turning on passcodes protects all of the data on the device (including your apps), it can be bypassed by jailbreaking. Data protection encrypts your e-mail messages and their attachments; it can’t be broken even if the passcode is stripped by jailbreaking. Data protection is also available for programmers to use in apps, but few take advantage of it. (At this time, there aren’t any jailbreaks for the iPad 2, so the basic encryption is still safe; but that probably won’t last forever).

To make the iPad’s built-in security features even more powerful, you can use Apple’s (now poorly named) iPhone Configuration Utility . Designed to help enterprises manage iOS devices, it opens up a suite of additional security and business settings, even for individual users.

To start, click on Configuration Profile -> New, and select Passcode from the list that appears. In the subsequent Passcode pane, you have all kinds of options; the settings here override your iPad’s. At the very least, you can specify a minimum length to the passcode.

To activate these password settings, you’ll have to fill in some information on the General tab too—specifically, the name and identifier of the profile. If this is a device that only you will use, you can set the Security drop-down to Always. (That allows you to remove the profile whenever you want.) If you’re configuring an iPad to be used by someone else, you can set it for Never or With Authorization (and then provide a password) so that someone else can’t change the settings without your permission.

How to Download Yahoo Email

There has been a time when Yahoo used to offer free POP3 access to Yahoo Mail service but now Yahoo offering POP3 access service as premium, which means that users had to pay to use it. So users were no longer able to download emails from Yahoo Mail using desktop email clients like Outlook or Thunderbird. Thanks to Google for awesome feature in their Gmail from which you can download your important Yahoo mails.
