ある企業が最近、5 つのメイン Web サイトが攻撃者の Web サーバーに誘導され、攻撃者が無防備な顧客から資格情報を取得できるようにする攻撃を経験しました。この種の攻撃が将来発生しないようにするために、会社が実装する必要があるのは次のうちどれですか?
正解:C
Explanation The attack described in the question is known as a attack. In this type of attack, an attacker modifies the DNS records of a domain name to redirect traffic to their own server. This allows them to intercept traffic and steal sensitive information such as user credentials. To prevent this type of attack from occurring in the future, the company should implement C. DNSSEC. DNSSEC (Domain Name System Security Extensions) is a security protocol that adds digital signatures to DNS records. This ensures that DNS records are not modified during transit and prevents DNS hijacking attacks.
