Email authentication refers to a set of techniques and protocols used to verify the authenticity and integrity of email messages and their senders. It helps prevent email spoofing, phishing, and email-based attacks. Common email authentication methods include SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance).

Email Encryption
Email encryption is the process of encrypting the contents of an email message to protect its confidentiality and integrity during transit. It ensures that only authorized recipients can access and read the email by encrypting the message using encryption algorithms and keys. Email encryption safeguards sensitive information, such as personal data, financial details, or classified information, from unauthorised access or interception.

Email Filtering
Email filtering is the process of inspecting and analysing incoming and outgoing email messages to detect and block spam, phishing attempts, malware, or other unwanted or malicious content. Email filtering solutions use various techniques, including content analysis, blacklisting, whitelisting, reputation-based filtering, and heuristics to classify and filter emails based on predefined rules and policies.

Email Security
Email security encompasses measures and technologies implemented to protect email communication from unauthorised access, tampering, data loss, or other security risks. It involves deploying secure email gateways, spam filters, encryption, digital signatures, and user awareness training to mitigate the risks of phishing, malware, data breaches, or email-based attacks.

Encryption is the process of converting plain or readable data into an unreadable format known as ciphertext using encryption algorithms and keys. It is used to protect the confidentiality and integrity of sensitive information during storage, transmission, or processing. Encryption ensures that even if data is intercepted or accessed by unauthorised parties, it remains secure and unusable without the appropriate decryption key.

Encryption Algorithm
An encryption algorithm is a mathematical procedure or set of rules used to encrypt and decrypt data. It defines how plaintext is transformed into ciphertext and vice versa. Encryption algorithms can vary in complexity, strength, and suitability for different security requirements. Common encryption algorithms include Advanced Encryption Standard (AES), RSA, and Triple Data Encryption Standard (3DES).

Encryption Key
An encryption key is a piece of data or a secret value used in encryption algorithms to transform plaintext into ciphertext or vice versa. The key is required for the encryption process to produce the ciphertext and for the decryption process to recover the original plaintext. The strength and secrecy of the encryption key are crucial to maintaining the security of encrypted data.

Endpoint Detection And Response (EDR)
Endpoint detection and response (EDR) is a cybersecurity solution or technology that focuses on detecting, investigating, and responding to security incidents or threats on endpoints, such as desktops, laptops, servers, or mobile devices.
