CHP 11 Flashcards
fact
UDP is connectionless
TLS
Transport Layer Security (TLS)
Security protocol that uses certificates for authentication and encryption to protect web communications and other application protocols.
fact
TLS 1.3 is the removing the ability to perform downgrade attacks
SASL
Simple Authentication and Security Layer (SASL) is a framework for adding authentication support to connection-based protocols.
MIB
A Management Information Base (MIB) is a database used for managing the entities in a communication network. It is a hierarchical structure that stores information about network devices and their operational status, enabling network management protocols like SNMP (Simple Network Management Protocol) to monitor and control these devices.
STARTTLS
STARTTLS is a command used to upgrade an existing plaintext communication connection to an encrypted connection using SSL/TLS. It is commonly used in various email and messaging protocols to secure the data transmission. STARTTLS method is generally more widely implemented than SMTPS
IMAP
Internet Message Access Protocol (IMAP) is a standard email protocol that allows users to access and manage their emails on a mail server. Unlike POP3, which downloads emails to a local device, IMAP stores emails on the server, allowing access from multiple devices.
SPF
Sender Policy Framework (SPF):
Purpose: Stops email spoofing.
DKIM
Domain Keys Identified Mail (DKIM):
Purpose: Ensures email integrity.
DMARC
Domain-based Message Authentication, Reporting & Conformance (DMARC):
Purpose: Combines SPF and DKIM to protect against email fraud.
S/MIME
Secure/Multipurpose Internet Mail Extensions (S/MIME) is a standard for public key encryption and signing of MIME data. It provides a way to send and receive secure email messages.
DNS
Domain Name System (DNS) is a hierarchical and decentralized naming system used to translate human-readable domain names (like www.example.com) into machine-readable IP addresses (like 192.0.2.1).
fact
DoS attacks are hard to perform against the servers that perform Internet name resolution, but if an attacker can target the DNS server on a private network, it is possible to seriously disrupt the operation of that network.
BIND
BIND (Berkeley Internet Name Domain) is the most widely used DNS server software on the Internet. It translates domain names into IP addresses and vice versa, facilitating the proper routing of internet traffic.
DNS Footprinting
DNS Footprinting is the process of gathering information about an organization’s DNS infrastructure and associated domains. It is often a preliminary step in a broader cybersecurity assessment or penetration testing exercise.
