Domain Name System is what DNS stands for and in simple English it is the phone book or doctors surgeries paper index listings of the internet. When you go to bing.com you don’t actually go to bing.com, your query is resolved to a single IP address or multiple. Humans are not good with remembering numbers, well remembering something simple like 888.com is easy though it still goes to a IP address, for everything else DNS does it for you. It also holds email records, sub domains, domain aliases and more.
Why am I randomly writing about DNS you will wonder when plenty of other people wrote about it many years ago? Yesterday randomly I typed in express.co.uk without the www and without the use of a search engine. I ended up at a completely random website: https://app-a702.mangahigh.com/en-gb/login - screenshot below.
The virtual cyber world and the physical security of your home front door are barely linked… if you don’t have IoT or any connected door locks that is! Before buying my first property I knew nothing about security options for front doors. A random topic you may think but read on and you will see my point. The front door on your home is often UPVC and has many components, for now let’s focus just on the Euro Cylinder lock and the door handle. The Euro Cylinder, everyone argues, is the weakest part of the door since it is the most exposed item and you can try to: drill it, bump it, screw it, pick it or snap it.
Euro Cylinders range from £10-£60 and come in standard, high and maximum security. High is 1* and maximum is 3*, these are British kitemarked and often come with Secure by Design as well. Door handles are either rated 2* or have no rating. You can either buy a 1* lock and 2* door handle to achieve the maximum 3* rating for your door security or just buy a 3* lock. If you have spent hundreds of thousands on a home (London of course), surely you can afford tens of pounds on a good lock and/or handle? The Kitemark or Secure by Design means it has been physically inspected for build quality and an assortment of physical attack tests have been run against the product before it gets a stamp.
