On-Line Monitoring of Expiration of DNSSEC Signatures
Mrázek, Jakub ; Polčák, Libor (referee) ; Matoušek, Petr (advisor)
In the bachelor thesis we have described computer software (programme) which is supposed to check the signatures of DNS (Domain Name System) records (resource records) and warn in due time about the expiry date or the approaching expiry date of the signatures in order to prevent from expiring. In the paper we have specified the DNSSEC (Domain Name System Security) technology, new resource records for the DNSSEC and details of signing the resource records. Moreover, we have introduced the programme itself, the possibilities of setting the programme, the ways of data reading and warning output. Since no such programme exists, and because there is a need to check the signatures quickly and warn about their expiry date, we have decided for this work.
