Wi-Fi security gets a boost as WPA3 standard is launched



The new wireless security protocol is poised to make hacking Wi-Fi connections a whole lot harder

 The wi-fi Alliance on Monday officially launched WPA3, a new wi-fi security protocol that is designed to enhance wireless security.

 The new standard "adds new features to simplify Wi-Fi security, enable more robust authentication, and deliver increased cryptographic strength for highly sensitive data markets," according to the Wi-Fi Alliance, a nonprofit group that certifies Wi-Fi networking standards.

 The latest iteration of WPA (short for "Wi-Fi Protected Access") comes in two flavors - personal and enterprise. They share a number of features, such as the latest security methods and the non-acceptance of legacy protocols, but each mode of operation also contains additional capabilities that take into account differences between the usages of, and requirements for, home versus enterprise networks.

Key improvements

One of the notable security enhancements brought by WPA3 resides in protection against password - guessing attacks, such as dictionary attacks, i which malefactors take countless stabs at a password in a bid to arrive at the right one.
This new safeguad is thanks to an authentication handshake called Simultaneous Authentication of Equals (SAE) and also applies to cases when users choose simple and easy-to-break password - a very common scenario indeed.

In addition, WPA3 supports forward secrecy, meaning that even if a password is compromised, attackers can't decrypt Wi-Fi traffic transmitted prior to the intrusion. Of note is also the fact that the new features don't impose any extra burden or inconvenience on the user.

For enterprise networks, WPA3 "offers the equivalent of 192-bit cryptographic  strength, providing additional protections for networks transmitting sensitive data, such as government or finance".

In addition, the Alliance announced Wi-Fi Easy Connect, which is a feature that is intended to securely get devices with limited or no display interface - notably Internet-Of-Things (IoT) gadgets - onto a network by scanning QR codes with a smartphone.

Do you find it hard to resist using free Public Wi-Fi? If so, the Wi-Fi Alliance has some good news for you too. The announcement on launching WPA3 also notes the release earlier this month of Wi-Fi CERTIFIED ENHANCED OPEN, a technology that supports individualized data encrypted in a bid to counter the risk of threats such as Man-In-the-Middle(MiTM) attacks.

WPA3 is a successor to WPA2, which was launched way back in 2004 and is widely used for securing Wi-Fi traffic. WPA2 security was recently in the spotlight after researchers found that the protocol suffers from a series of serious flaws that they subbed 'KRACK' Although many devices manufactures have since sealed up the cracks, the discovery highlighted concerns surrounding wireless connections.

It remains to be seen when WPA3-enabled products will enter the market, althrough it is very likely to take quite some time before they reach broad implementation. For the time being, WPA3 is optional for newly-manufactured devices and it retains interoperability with WPA2 devices through a transitional mode of operation, said the Wi-Fi Alliance.

Top Things NOT to do in an interview

Image
Body Language Mistakes to Avoid: 1. Not Making eye Contact. Two thirds of hiring managers (67 %) say that failing to make eye contact is one of the biggest body language mistakes job candidates make. This could be because not looking someone in the eye appear as if you're trying to hide something and are therefore untrustworthy. 2. Refusing to smile. Failing to smile is a major concern among 39% of hiring mangers. Aside from giving off the impression that you're cold or standoffish, not smiling also tells hiring mangers that you'd rather be anywhere else. 3. Playing with something on the table. One third of hiring managers (34%) have witnessed a candidate playing with something on the table during the interview. It shows a complete lack of interest in the interview - and disrespect for the manager's time. 4.Fidgeting too much in your seat. Is there some place more important you have to be? This is the message you send hiring managers when you fidget to...

No More Open non-HTTPS sites

Image
From 24 July 2018 with the release of Chrome 68, Google Chrome prominently marks all non-HTTPS websites as 'Not Secure' in its years-.long effort to make the web a more secure place for Internet users. So if you are still running an insecure HTTP website, many of your visitors might already be greeted with a 'Not Secure' message on their Google Chrome browser warning them that they can't trust your website to be secure. By displaying 'Not Secure,' Google Chrome means that your connection is not secure because there is no SSL Certificate to encrypt your connection between your computer and the website's server. So, anything sent over a non-HTTPS connection is in plain text, like your password or payment card information, allowing attackers to snoop or tamper with your data. Timeline of Not Secure Warning on Google Chrome This significant transition has not occurred overnight, Google intentionally processed it slowly over the period of a few...
