Secure your files from Ransom Malware Encryption on Windows 10.

Hi Guy & Girls,

Well, you’ve just upgraded to the current Windows 10 Fall Creators update and you find a few goodies under the bonnet?

No? Well there is an option to turn on a feature called “Controlled Folder Access” on their Windows machines

It’s described here. So, I will not re-invent the wheel.

But, basically. It keeps an eye on the activity of the Hard Drive and stops mass encryption occurring on both the System files and the Specific User Local folders that are currently active.

The Hit on the system performance is not noticeable and certainly will not be noticed on an SSD.

So, a bit of a no-brainer!

So, if you are already on Windows 10 Fall Creators do it today!

If you aren’t. It actually makes the pain of upgrading worthwhile. That from a Computer Engineer that normally would say hold off the update for at least 3 months.

But this is a sensible improvement worth the risk.

Yes, they have moved all the settings around again. But, the underlying improvement of speed of the new OS makes it worth the pain of the upgrade.

So, hold your nose and upgrade to Windows 10 Fall Creators soon!

Cheers.

WPA2 – Broken : In the middleman attack possible.

Guys & Girls.

For those of you that remain wedded to the earlier versions of Windows – W95/W98/W7 & W8.0 & 8.1?

You should note that the WiFi element of communication has been found wanting again.

For further details click on here.

If you are on Windows 10 / Windows 10 mobile you can relax this time as it has already been patched as long as you have been allowing Windows to update itself.

Cheers

Tagware Crew goes to Future Decoded at Excel – Microsoft 2016 Server & Cloud

Microsoft Windows Server 2016 is on its way!

All the best bits were highlighted in another session I went to. One of the main ones was the Microsoft 2016 Servers ability to interact with TPM version 2.0. In a nutshell, this allows the ISP or Cloud provider to point to the owner should our friends NSA or GHCQ want to look at the server. Microsoft has nice sidestepped the issue of encryption. As with TPM 2.0 enable hardware. If, you can’t talk to the certificate holder for that hardware. Nothing is going to happen.  You can bounce in a pick up the Hard drive or the complete unit. Without the system being able to retrieve the certificate. Then, the whole lot is grounded. Wiping out any of the drives will just provide an encrypted drive that you cannot read on any system that cannot talk to its Security systems. Nicely, done there Microsoft. That should stop your friends in government putting you in an untenable position in terms of data security.

Dawson and I seem to think we were the only old plods left!

The young smiling face of youth. I remember when I was that bouncy! Secondly, that this Cloud stuff it is very busy and noisy by all accounts. I’m still waiting for Air Traffic control to come to a sort this mess out!

But, as I was walking around the show. I had a feeling that I got when I watched  Chitty chitty bang bang many years ago. When the Child catcher turns up with sweets and ice cream. All of which were free.

 

Until of course the cage is closed and the pretty decorations come down!

Don’t forget. If, you do set up on Cloud. Make sure that you can migrate away should you need to. Or, you may end up with a larger bill than the CIO was expecting.

Well, that’s me done for today.

As always. If you have a comment. Please feel free to do so.

Speeding up Internet connections.

We are currently hearing a lot about download speed of the Internet in the UK press.

However, one of the most overlooked timings is the response of DNS queries. OK, too technical.

When you type a URL (Uniform Resource Location) or for the non-tech crew. www.google.co.uk for example, a number of processes occur before the content of the website is brought to you browser.

It’s demonstrated here visually for those who want to see what happens. The time that this process takes from you typing in the URL you want in your browser to it finding the IP address of the server can be a significant time.

As most ISP’s (Internet Service Provider) be they ADSL or Cable type run the own DNS servers theses generally can become flooded with requests, they then tend to become slow in responding to finding the IP address of the server. It’s very similar to you driving along the M25 or M62 at peak times. You do get to the destination, eventually! But, it can take 10 mins out of peak traffic or over an hour in.

By using an external DNS server, they are available where ever you may find yourself in the world and they can still be used if you are sitting in an airport or hotel reception. As the external DNS servers are teamed together around the globe they provide a faster response than that of local ISP.

Now, I can hear you say. “it will be extra m/s’s to respond”. True, but because the web pages are now filled with content from other sources than the original site itself. These extra times will quickly build up to make you weep when browsing.

If each section of the website is provided by a 3rd party (Goggle ad’s for example) and takes a 0.25 of a second to resolve, that’s 5 seconds added to a typical web page load. Five seconds may not sound like much. Count it out loud… it’s a long time, isn’t it? Normally, this leads to the accusation that the ISP is not providing the download speed advertised.

But as experts, we know that it is normally DNS resolution and Latency that provides these issues. Not bandwidth!

That said if an ISP is saying it provides an 8Mb circuit in bold lettering. It should also be forced to show the contention in the same bold text. Normally, this is 1-25 or 1-50.  So, divide that 8Mb by 50 and you get 160K/b a second on a bad day, if everyone uses the resource at the same time. That will make your IPlayer session come to a halt. As being video it needs between 2.4-3.6Mbit a second.  But, most web pages are kept slimmer than this. As the guys hosting the websites know, we pay for the amount of bandwidth we use. So, those pretty web pages are very economical with the bandwidth size they use.

An additional feature of using external DNS servers are there ability to flag bad server IP’s. Such as the ones that are trying to obtain you Credit Card or Banking information. So, whilst they are not totally 100%. As nothing is! They quickly become aware of servers IP that is being used for such activity. As they know the IP servers for Barclay’s bank over the world and will flag this in your browser.

So, what’s involved?

It’s quite simple really to try the speed improvement out. You don’t need to download any software, as what you need is already there and it costs you nothing. So, give it a try.

There are two methods. First, is to change the DNS settings on your router. This makes all of the PC’s / Apple systems use the external DNS servers.

Or, to change the settings on a PC or Apple system individually. Now, unless you are technical. I would suggest starting by changing the PC settings. Unless you have more than 3-4 systems.

This is how you do it.

If you have broadband

  1. Click Start > Control Panel > Network Connections and select your local network.
  2. On the General tab click Properties > Internet Protocol (TCP/IP).
  3. Click Properties

Now, be careful here. You only want to change the DNS section. Leave the allocation of IP address alone. This will normally be set to obtain an IP address from DHCP server.

The Internet Protocol window will appear. Click Use the following DNS server addresses and enter the DNS server(s) you want to use.  You will have to select Manual allocation as normally this will be set to Automatically obtain. I would suggest the following. note: If your DNS settings have numbers in them. Then, make sure you take a note of what they are. Just in case you want to go back to these settings later.

156.154.70.1
156.154.71.1

Move the mouse pointer to the first of the DNS boxes. Far left-hand side. Then, type the figure and full stops into the boxes. Then, proceed to the next line below. Again, type the numbers and full stops into the boxes.

Once, you have completed this then select ‘OK’ until you return to the Network settings. Then, select cross on the top right-hand side, to return to the desktop. Launch your browser and hopefully, you should notice an improvement in speed when browsing.

Enjoy and as always constructive comments are welcome.
