What are the key differences between domain hijacking and DNS poisoning, and how can organizations protect their online assets from these threats?

Domain hijacking involves unauthorized access to a domain registrar account to change the registration information of a domain, while DNS poisoning involves manipulating the DNS server to redirect traffic to a malicious website. To protect against these threats, organizations should use strong authentication methods, regularly monitor domain registration information, implement DNS security measures like DNSSEC, and conduct regular security audits.
