A cache poisoning vulnerability exists in Windows DNS Server. An attacker who successfully exploited this vulnerability could insert false or misleading DNS data in the response to specific DNS requests, thereby redirecting Internet traffic. **What causes the vulnerability?**

Microsoft Windows 2000 Server, Windows Server 2003 and Windows Server 2008 contain a vulnerability that could allow an unauthenticated, remote attacker to cause the storage of false IP addresses for valid domain names within the local DNS cache. The vulnerability is due to errors in processing DNS requests. Choosing Hostnames to Be Poisoned When performing this attack, we will basically find two different scenarios: 1. The first scenario is in which the attacker machine, the victim, and the DNS server are all in the same network segment (certainly less common). Jul 02, 2017 · • DNS cache locking • DNS socket pool • DNSSEC. Before we start the step by step to implement the DNS Security, lets go through a theory behind this technology. DNS Cache Locking. Cache locking is a Windows Server 2016 security feature that allows you to control when information in the DNS cache can be overwritten. There has been a long history of attacks on the DNS ranging from brute-force denial-of-service attacks to targeted attacks requiring specialized software. In July 2008 a new DNS cache-poisoning ( See our slideshow on how DNS cache poisoning works, and what can be done to prevent attacks ) With cache poisoning an attacker attempts to insert a fake address record for an Internet domain This allows attackers to perform cache poisoning attacks against this nameserver. If the host allows these recursive queries via UDP, then the host can be used to 'bounce' Denial of Service attacks against another network or system. Solution

A DNS server caches the Host (A) record and all queried NS resources that are in the DNS server zone. In this case, DNS can also cache the NS record of an unauthorized DNS server. This event causes name resolution to fail or to be appropriated for subsequent queries in the specified domain.

Also known as DNS spoofing, DNS cache poisoning is an attack designed to locate and then exploit vulnerabilities that exist in a DNS, or domain name system, in order to draw organic traffic away from a legitimate server and over to a fake one.

The DNS software administrator has not configured the DNS software to send all log data to either the system logging facility (e.g., UNIX syslog or Windows Application Event Log) or an alternative logging facility with security configuration equivalent to or more restrictive than the system logging facility.

This allows attackers to perform cache poisoning attacks against this nameserver. If the host allows these recursive queries via UDP, then the host can be used to 'bounce' Denial of Service attacks against another network or system. Solution Mar 28, 2014 · DNS cache poisoning attack shutting down my internet and keep on comin Hi, It has been a long time since this errors started,It is disappearing when I flushing my DNS, but it always comes back and annoys.. I have Eset SmartSecurity 5 and when this attack comes I get a meesage like this: " Detected DNS cache poisoning attack IP:.. The DNS software administrator has not configured the DNS software to send all log data to either the system logging facility (e.g., UNIX syslog or Windows Application Event Log) or an alternative logging facility with security configuration equivalent to or more restrictive than the system logging facility. Oct 20, 2016 · DNS Caching: Windows caches DNS look ups, and some programs may do so as well. You may want to flush the Windows DNS Cache, and the cache of the program you are using if it uses one, to find out if old entries may have caused the loading issues. In Chrome, you may load chrome://net-internals/#dns and click
