C1b3rWall Academy’s cybersecurity in networks and architectures module delves into the DNS database, its security issues / attacks, points of improvement and system upgrades.

“DNS Firewall. Improving DNS to avoid headaches” is the title of the lecture that belongs to Module 1 of C1b3rWall Academy 2021: “Networks and architectures”, which is taught by Juan Antonio González Ramos, programmer of the Computing Services of the University of Salamanca, who has held the role of Webmaster of the Organization (2000-2005), Web Hosting Manager (2005-2010) and Head of the Systems Unit (2010-2020). He currently works as a marketing data analyst at the University’s Innovation Department.

DNS databases are distributed, hierarchically organized and comply with a standard defined by RFC 1035 and 1035 of 1987, which are now quite obsolete.

DNS have been experiencing security problems for several years. At the moment, the software is vulnerable, for example, to DoS/DDoS denial-of-service attacks. They can also be subject to failed or faulty configurations, as well as cache poisoning or DNS spoofing, all because the specifications do not include security features, so these systems need to be upgraded and updated. The improvement of this system is DNS firewall. You can read the full article on News-365.

If you would like to learn about this topic and other issues related to DNS-dependent attacks and their areas requiring improvement, do not miss the opportunity to enrol in C1b3rWall Academy 2021 for free.
