Domain-based Message Authentication is a set of standards used to ensure the authenticity and integrity of email messages by verifying the sender's domain through DNS records. It helps prevent email spoofing and phishing by allowing domain owners to publish policies on how to handle unauthorized emails.
Relevant Fields:
Concept
Email authentication is a collection of techniques used to verify that an email message originated from the source it claims to have come from, aiming to prevent email spoofing and phishing attacks. It enhances email security by enabling email providers to detect and block fraudulent messages before they reach the recipient's inbox.
Concept
DomainKeys Identified Mail (DKIM) is an email authentication method that allows the sender to associate a domain name with an email message by affixing a digital signature to it. This helps email receivers verify the legitimacy of the sender and protects against email spoofing and phishing attacks.
Concept
Sender Policy Framework (SPF) is an email authentication method designed to detect and block email spoofing by verifying the sender's IP address against a list of authorized IP addresses published in the DNS records of the domain. It helps prevent spammers from sending messages with forged 'From' addresses on behalf of legitimate domains, thereby enhancing email security and trustworthiness.
Domain-based Message Authentication, Reporting & Conformance (DMARC) is an email authentication protocol designed to give email domain owners the ability to protect their domain from unauthorized use, such as email spoofing. It works in conjunction with SPF and DKIM to provide a mechanism for receiving email servers to determine if incoming messages align with the policies set by the domain owner and to report back on their findings.
Concept
Email spoofing is a cyber attack technique where the attacker sends emails with a forged sender address, making it appear as if it comes from a trusted source. This deception is often used to trick recipients into divulging sensitive information or to spread malware.
Concept
Phishing is a cybercrime technique where attackers impersonate legitimate entities to deceive individuals into revealing sensitive information, such as passwords and credit card numbers. It often involves fraudulent emails or websites that appear authentic, exploiting human trust and lack of awareness to gain unauthorized access to personal data.
Concept
DNS records are essential components of the Domain Name System that store information about domain names, translating human-readable addresses into IP addresses necessary for locating devices on a network. They enable the functioning of the internet by directing traffic to the correct servers, ensuring that users can access websites and services efficiently.
Concept
Email security encompasses the techniques and measures used to protect email accounts and communications from unauthorized access, data breaches, and other cyber threats. It is critical for safeguarding sensitive information and ensuring the integrity and confidentiality of digital communications in both personal and professional settings.
Concept
Internet Protocol (IP) is a set of rules governing the format of data sent over the internet or local network, ensuring data packets are addressed and routed to their intended destinations. It is a fundamental component of the Internet Protocol Suite, which is essential for inter-network communications and is used in conjunction with other protocols like TCP and UDP to facilitate reliable data transmission.
