Wireless Encryption WPA2 Vulnerability – “Krack”

WPA2 Krack Vulnerability

Today, a vulnerability was published about WPA2 encrypted networks, the most commonly recommended encryption method available to protect WiFi devices.

An attacker within wireless range of a victim can exploit these weaknesses using key reinstallation attacks (KRACKs). An attacker can use this attack technique to read information that was previously assumed to be safely encrypted by the WPA2 encryption mechanism. The “Krack” method can be used to steal sensitive information such as credit card numbers, passwords, photos or any data sent via the wireless connection.

NB. Any WiFi enabled device is vulnerable – Apple, Android, Linux, BSD and Windows.
To ensure your wireless devices are secure, updates must be loaded as soon as they are available.

Website page loading time a factor in Google rank

Website page loading time Website Maintenance

Did you know your website page loading time is a Google ranking factor? Google is all about user experience, if your website is slow you will be penalised.

It is no secret that Google is all about efficiency, performance and awesome customer experience. Google knows that to give the user a good experience they shouldn't be waiting.

A fast site will retain users, a slow site will chase them away, simple as that. If you care about retaining your website visitors then it makes sense to optimise your website speed.

How Fast Should Your Website Page Loading Time Be In 2017?

The  desktop version of your site on a decent internet connection should load within 2 seconds.  This is the acceptable figure to maintain visitors. At 4 seconds you have lost 25% of your visitors and at 10 seconds you would have lost almost 50% of your site visitors.

Google provides a web performance tool, use it to get an indication of your website performance.

Recent Case Studies on Site Speed Performance

Ancestory.com recorded a 7% positive rise in conversions after improving the render time of web pages by 68%, reducing page bloat by 46% and reducing load time by 64%.

A presentation by AliExpress.com claimed they reduced load time for their pages by 36% and recorded a 10.5% increase in orders and a 27% increase in conversion rates for new customers.

Tips to make your computer faster

Taking forever for Windows to load, applications take an eternity to launch?

Over time, regular use of your computer builds up unneeded files on your hard disk. As the disk fills up it takes longer to read from the various segments on the disk. Neglecting to perform regular maintenance can add to poor computer performance.

Things you can do to speed up your computer.

  • Restart your computer more often. This closes unnecessary applications and results in a faster computer.
  • Uninstall unneeded applications. Frees up drive space and in some cases removes unneeded services that use up system resources.
  • Delete temporary files using "Disk Cleanup". Helps to free up drive space.
  • Remove unneeded browser plugins. Speeds up browser, frees up system resources.
  • Defrag your hard disk using "Defragment and optimise drives" Helps to arrange your files on your drive, increasing drive performance.
  • Make sure Windows updates are set to enabled and automatic. No-brainer really.
  • Upgrade outdated hard drives to newer Solid State Drives. These new SSD drives are the best thing since free antivirus, they greatly speed up Windows and application load times.
  • Upgrade system RAM (Memory). Once you click an application it launches itself into memory from disk (memory is many times faster than disk), if you don't have enough memory the system creates more "memory" by using (slower) disk, slowing your computer even more.
  • Run regular Antivirus scans. Malware (viruses) can slow down your computer by utilising system resources.
