Abstract

Unix operating system network security on the internet is very important. Various network security attacks appear to negative effect. One of the attacks that came up was the botnet. This botnet attacks performed by an attacker financial motive or theft of information by spreading Denial of Servise (DOS), the spread of malware, phishing and Domain Name System (DNS) poisoning. The use of public IP risk being attacked if there is no adequate security and the lack of security on the DNS server vulnerable to DNS Poisoning. This research is to simulate the prevention of attacks on DNS servers DNS Poisoning. Attack prevention mechanism in this study using a firewall Port Scanner Attack Detector (PSAD) and fwsnort that can prevent insecure network traffic and allow a secure network traffic. The design of the network uses a physical or virtual server computer that is connected to ip public. Stages of this research is the design of systems and networking, system implementation and system testing using Strees Testing. Based on the results of research conducted on the prevention of DNS poisoning attacks, DNS poisoning can be prevented using a firewall PSAD and fwsnort by blocking IP addresses, ports and suspicious packages. As its GUI using Snort IDS and Snorby. The results of the testing of Stress Test can be concluded that the performance of the DNS server is still running normally. This is evidenced by the percentage of 63.3% strongly agree and 36.7% agree with the system testing performed.
