DNS Security Management

DNS Security Management involves implementing and maintaining measures to protect the Domain Name System (DNS), a critical component of your network infrastructure. This includes safeguarding against DNS-based threats like cache poisoning, DDoS attacks, and domain hijacking. Effective DNS security management encompasses using secure protocols like DNSSEC to ensure data integrity, implementing response rate limiting (RRL) to mitigate DDoS attacks, and regularly monitoring and auditing DNS traffic for anomalies. 

Additionally, it involves ensuring proper configuration of DNS servers, keeping software updated, and using access control lists (ACLs) to restrict unauthorized access. Such comprehensive security practices are essential to maintain the reliability and trustworthiness of DNS services, crucial for the seamless operation of internet-based communications and services.
