In the previous video we have covered different Types of Mobile Devices and Operating System of mobiles. Today also we'll continue that in this video & understand Slider Type of Mobile phones. While we'll mainly focus on the topic, How Mobile Data Security should be done.
- Slider phones :
• The phone has two parts - one with the screen and speakers along with some keys, and the other half containing the main keypad.
• However, instead of folding, the bottom half with the keypad slider out form under the top half.
• This kind of design also allows the phone to be quite small.
• Also, in most cases, you can perform certain operations such as answering and ending calls and accessing the phone book and call history without opening the slider.
• Main Manufacturers of Slider type phones were Motorola, Nokia, Micromax, Samsung, & others.
Every Type of Mobile Phones have different market value and its functionalities which was varying from time to time.
- Mobile Device Security :-
• Android OS is easy to use but lacks in Data security while IOS has complicated using but at the same time it is very secured & user does not have any chances of data breaching.
• Only screen password & app locking is not complete device security, other wireless data security is most important than compare to all others.
• There are different levels of security that a wireless network can provide. Building on levels of security a network can provide, there are multiple types of Encryption.
- WEP (Wired Equivalent Privacy)
• The oldest and least secure of these different security levels is Wired Equivalent Privacy (WEP) which was introduced in 1997.
• This form of security for wireless networks is rarely used anymore due to its many security flaws.
• Is a security algorithm for IEEE 802.11 wireless networks.
• This is not a secure network in today's time as there are many hackers which can easily read our data from our device if we are using WEP security.
- WPA (Wi-Fi Protected Access) :
• Wi-Fi Protected Access (WPA) provides a more secure way of connecting to the network than WEP.
• Two different modes exist, personal mode or pre shared key (PSK) and enterprise or WPA-802.1X.
• PSK is most often used in small offices and homes, since it is meant for small amount of users.
• Enterprise Mode means that the user is using a username and password, or digital certificate, to authenticate to a server rather than using a preshared key.
• It is better than WEP but still not that much effective.
- WPA2 :
• The 802.11i standard, or WPA2, was released in 2004 and improves on the security mechanisms that WPA uses.
• WPA2 has the same two different modes that WPA comprises of.
• It is the latest and best privacy secure mechanism where three encryption works at three time.
Wherever there are free Wi-Fi networks available, please do not connect your device with it. It can possibly be attackers or hackers trying to reach to your mobile phone & wanting to breach your data.
Also, Turn OFF the mobile data when not in use.
