DNS Monitoring Tools


What is DNS Monitoring?

The DNS Monitoring Tools, it can protect non-online presence by periodically checking DNS records for unexpected changes or local outages due to human errors or malicious attacks. DNS records are a favorite of hackers and are often victims of human error. In addition to entering ISP accounts and changing values ​​directly, there are two basic ways for hackers to use DNS to crash a site.

DNS Poisoning

We have mentioned the previous DNS caching section. DNS poisoning occurs when someone adds incorrect information to the DNS cache on the server. The server with toxic entries for the site then responds to requests from the cache. Other servers and routers keep toxic records and spread poisons. These attacks often direct users to fake sites where hackers collect other information, such as user credentials and credit card information.

Poisoning can also occur due to human error. This is the case in California and Chile when users of DNS, Facebook, Twitter and YouTube are redirected to the Chinese site. The problem is the result of routing Chinese government ISPs to the root server in China, where they block these channels and direct them to state-controlled sites.

Ddos and Dos Attack

DDoS (Distributed Denial of Service) and DoS (Denial of Service) attacks occur when computers (Dos) or more (DDoS) begin to develop rapidly into DNS and a site to hit site supporting infrastructure. These attacks come in various forms that try to use all existing links that affect the server, affect performance, or completely in DNS Monitoring Tools.

Tracking can Help stop DNS Attacks on their Tracks

Monitoring DNS entries must be at the top of the priority list. If something goes wrong in the DNS records, it can endanger the entire system and reduce brand reputation. To monitor DNS, consider following the DNS aspects below. This is simple; The DNS query retrieves the IP address of the system and compares it to the given IP address (one or more addresses using regular expressions). If the IP address does not match, tracking will notify. If it supports IPv4 and IPv6, it must track records A (IPv4) and AAAA records (IPv6), because one might fail, and the other would not.

Soa Registration

The SOA record has a serial number that updates the system when changes occur anywhere in the DNS entry. Although tracking numbers does not tell what has changed, knowing that something has changed can help get out of the attack. Suddenly, imagine company emails and messages missing or bouncing everywhere to try to contact. Or worse, if someone hacked the system and forwarded messages and emails elsewhere? Monitoring MX and SRV data can help prevent loss of important communication lines.

Registration and Root NS Services

might want to test NS records to make sure nothing is damaging the primary and backup name server records. Test this name server directly to ensure that they respond with the correct name. Monitoring is the best way to keep DNS records secure and respond reliably. In general, it will find that DNS errors are localized and only affect part of the user base. Using a third-party tracking service with a large network of testing locations can help quickly capture even the most detailed local problems.

Results

IP networks and Internet communications are all based on DNS. Active tracking of notes can help prevent DNS attacks or interruptions. Find out customer complaints or reveal accounts rather than waiting with DNS Monitoring Tools.
