DNSSEC and HTTPS

 

The goal of this lab is to secure DNS zone from the lab 1 (i.e., enable DNSSEC) and then use the zone to build a micro CDN service. As a side effect, you will also learn how to create a simple HTTP/Apache server instance and serve simple files from there. In addition, the lab will also show you how you can secure web server with HTTPS certificate, a different level protection compared to DNSSEC. We will use tools provided by Let’s Encrypt CA and the process is quite simple, involves just running a few commands (but we will have an expected issue with it, for you to analyze).

Tasks
1. DNSSEC
Lab 1 left us hanging about the DNSSEC. This document (Links to an external site.) gives a quite comprehensive description of the DNSSEC, its internals, and what should happen to enable and maintain DNSSEC for your zone. I assume that you already read it.

Luckily, in order to enable DNSSEC in “regular” circumstances, Bind software since its recent version includes a very simple method to work with DNSSEC. It still requires a little bit of manual work, but only a little bit. Majority of the complex process is done by Bind software itself.

Sample Solution

All newborns, whether human or animal appear to be born with some innate bonding mechanism, relying on our birth mother to ensure our emotional and physical needs are met and to protect us from danger. It is in a way a form of survival. This forms the crux of Bowlby’s work on attachment, which grew out of his work with emotionally disturbed children. Making a connection between how these children coped being taken from their mothers at such a young age and any subsequent neurosis in later life formed the basis for his theories of attachment behaviour.

Bowlby proposed that the roots of any satisfying relationship must start at the beginning, between mother and baby; the infant must feel safe, secure and protected in order for a secure attachment (1979: 23) to take place. Many of our negative and positive personality traits about how we relate to others are linked to our earliest attachment experiences (1979: 127), and they are just as likely to get played out in the therapeutic relationship, hence the importance of understanding its significance and context in child development.

Examples of dysfunctional behaviour that can result in attachment issues in children include the caregiver being persistently unresponsive, rejecting or threatening. Childhood loss or trauma such as bereavement or extended absences from the attachment figure can also cause a child and adult “to live in a constant state of anxiety lest he lose his attachment figure” (Bowlby, 1979: 137).

Mary Ainsworth developed The Strange Situation test (Ainsworth et al, 1978: 32) as a way of classifying attachment behaviour. In essence the test involves an infant spending time in a room with its mother or a stranger. When the Mother returns to the room, the way the infant copes with the reunion is observed leading to four potential classification types being diagnosed for the infant. The four attachment styles are secure, avoidant, resistant and disorganised, and each of them reflects the quality of the relationship between mother and infant, indicating potential attachment concerns in later life (Ainsworth et al, 1978: 120 – 124).
