DNSSEC

DNSSEC introduces security at the infrastructure level through a hierarchy of cryptographic signatures attached to the DNS records. Users are assured that the source of the data is verifiably the stated source, and the mapping of name to IP address is accurate. DNSSEC-compliant name servers also provide denial of existence, that is, they tell a user that a name does not exist. There are two dominant strategies: (1) a process that zone operators can initiate for digitally signing their own zones by employing public-private key pairs and (2) a chain of trust between parent and child that enables the system eventually to become trustworthy.

Root Servers

A root name server is a DNS server that answers requests for the root namespace domain, and redirects requests for a particular top-level domain (TLD) to that TLD's nameservers. Although any local implementation of DNS can implement its own private root name servers, the term "root name server" is generally used to describe the thirteen well-known root name servers that implement the root namespace domain for the Internet's official global implementation of the Domain Name System.

All domain names on the Internet can be regarded as ending in a full stop character e.g. "en.wikipedia.org.". This final dot is generally implied rather than explicit, as modern DNS software does not actually require that the final dot be included when attempting to translate a domain name to an IP address. The empty string after the final dot is called the root domain, and all other domains (i.e. .com, .org, .net, etc.) are contained within the root domain.

CSIRT

CSIRT stands for Computer Security Incident Response Team.

CSIRT is assigned with the responsibility of assisting members of the local internet community in implementing proactive measures to reduce the risks of computer security incidents and to assist the community in responding to such incidents when they occur.

The CSIRT-KENYA is sponsored by the Kenya Network Information Center (KENIC) and Telecommunications Service Providers of Kenya.
