250,000 HACKED USER ACCOUNTS: TWITTER TO INTRODUCE  TWO-FACTOR AUTHENTICATION Following the recent attack on twitter over the weekend which resulted in compromise of over 250,000 users accounts, twitter is on the look-out for a competent software engineer to implement additional security layer for user logins to the social media cum micro-blogging website. Two-factor (multi-factor) authentication is a way of adding additional layer of security in addition to the regular username and password combination, usually in the form of additional random token generated by a hardware or software, or even a message received via SMS which is valid for a short period of time and cannot be chosen by the user or a potential hacker. It has become obvious that multi-factor authentication is the way to go in handling the simple but ever important authentication question of "who are you" we encounter on on web login forms every now and then!

What is Mobile Network Portability (MNP)? Mobile Number  Portability allows mobile telephone users to migrate from one service provider to another and still retain their telephone numbers. It provides a platform whereby a subscriber on any of the existing GSM and some of the CDMA networks can switch from one service provider to another and still retain their phone numbers. For instance, with your current MTN line you can decide to migrate to ETISALAT or vice-versa, and still retain your "stable and popular" phone number. How MNP Works For instance, subscriber A whose original service provider is network P, might wish to change or port to network Q. This can be achieved by subscriber A sending a porting request to network Q, network Q sees the request coming from a user on network P and then contacts them accordingly to setup the process of exchange and transference of subscriber details, this is the most common and it is known as "Recipient-led" porting. Once a...

At one time or the other, you may have used or heard such expressions as “Downloading file from server”, “server is slow”, “Authentication required for server access”, and so on. These are everyday expressions used in the present Information Age. Now let us take a closer look at what a server really is, with emphasis on the type of server that makes it possible for access to the Information Superhighway – the Internet, known as Web Servers , as well as what actually happens when an internet user tries to access a website via a Web Browser by sending a (Hyper-Text Transfer Protocol) HTTP request to the web server. WHAT IS A SERVER? A server is basically a computer program that serves some sort of content to a client using a specified protocol. The term server also refers to the computer or virtual machine running the server program, which in fact is the most common use and understanding of the term. Today, most enterprise organisations with computer network infrastructure do host th...

Yes you can share that USB modem internet connection on one PC with other PCs over an ad-hoc wireless network, even without a switch or wireless router. This is made possible with Internet Connection Sharing (ICS) , a network service/feature of all windows-based systems. The sharing can also be done just between two PCs connected using an Ethernet cross-over cable. How Do I Share My USB Modem Internet Connection With Other PCs Without A Switch/Router, Over My Ad-hoc WLAN? Steps: 1.      1. Connect the USB modem (e.g. MTN 3G USB modem) to the host computer. 2.              Enable ICS on the USB modem connection properties and select the network type    through which you desire to share (e.g. Wireless Local Area Network connection) 3.   Select the services you would want to run by clicking   Settings. The basic services you need in order to access the internet are DHCP, DNS, HTT...

With fast-paced Information Technological advancements in the present Information Age, every one seeks to be enlightened so as to be relevant and up-to-date. For instance, everyone wants to get the best out of their IT gadgets, and would want to know what features and functionality such gadgets can offer. Some time last month, I overheard someone saying; "What's all these Wireless LAN, WLAN, Wi-Fi, 802.11b/g/n stuff?" "Why does my brand new laptop PC have this Wi-Fi logo and 802.11b/g beside it, while my friend's has 802.11b/g/n instead, and he calls it wireless-N. What difference does that make?" "In fact I need a faster browsing speed each time I want to browse the internet using any of these wireless Cybre cafes." These and many more are questions asked by people all around the world. However, the good news is that the answers to these and other related questions are such interesting and would make one's IT experience more enjoyable......

In order to create a WLAN, a few basic components are required, which include the following; 1.The wireless client devices; equipped with a wireless Network Interface Card (wireless NIC) 2.The Access Points (AP) or control module 3.The wired LAN backbone The Wireless Client Devices PDA Laptop PC This simply refers to users’ devices such as desktop computer systems, laptop computers and mobile gadgets like the Personal Digital Assistants (PDAs) and smart phones. They have embedded wireless Network Interface Card (wireless NICs) which enables users to have access to the wireless network. The wireless NIC is a hardware device that connects a computer to a network so as to send and receive data. A wireless NIC has an antenna, either internal or external, while a wired NIC has a port (usually an RJ-45 port for cable connection). The cable connects the NIC to the network, thus establishing a link between the computer and the network. A wireless NIC performs same functio...
