The Federal Information Security Modernization Act (FISMA) is a United States federal law enacted to enhance the security of information systems used by federal agencies. The original act, known as the Federal Information Security Management Act of 2002, was part of the E-Government Act of 2002. FISMA mandates that each federal agency develop, document, and […]

An A record (Address Record) is a DNS (Domain Name System) record that maps a domain name to an IPv4 address. It allows users to access websites using easy-to-remember domain names instead of numerical IP addresses. Learn more: https://en.wikipedia.org/wiki/A_record

Endpoint security refers to the practice of protecting endpoint devices—such as computers, smartphones, tablets, servers, and IoT devices—from cyber threats and unauthorized access. It involves deploying technologies, policies, and processes to secure these devices, which act as access points to an organization’s network, from being exploited as attack vectors.

An endpoint refers to any device or node that connects to a network and interacts with other devices or systems. Endpoints are considered the entry or exit points for communication within a network and are often a target for cyberattacks. Common Types of Endpoints: User Devices, Desktop computers, Laptops, Smartphones, Tablets Learn more: https://en.wikipedia.org/wiki/Endpoint

Disaster recovery (DR) refers to the strategies, policies, and procedures an organization implements to recover and protect its IT infrastructure, data, and applications after a disaster or significant disruption. The goal of disaster recovery is to minimize downtime, restore operations quickly, and prevent data loss in the event of natural disasters (e.g., floods, earthquakes), human […]

Deep Packet Inspection is a method of inspecting network traffic at a detailed level, analyzing the content of packets that are being transmitted across the network to detect malicious activity or violations of security policies. DPI technology became important for detecting advanced persistent threats (APTs) and identifying hidden vulnerabilities in encrypted traffic. Learn more: https://en.wikipedia.org/wiki/DPI

DMARC (Domain-based Message Authentication, Reporting, and Conformance) works by leveraging SPF and DKIM to authenticate incoming email messages. For an email to pass DMARC, it must pass either SPF or DKIM (or both), and the domain used in the From header must match the authenticated domain. Learn more: https://en.wikipedia.org/wiki/DMARC

Data Loss Prevention (DLP) is a set of cybersecurity strategies, tools, and technologies designed to prevent unauthorized access, sharing, or leakage of sensitive information outside of an organization. DLP systems monitor and control data transfers, both within the organization and externally, to ensure that sensitive data (such as financial records, personal information, or intellectual property) […]

DKIM (DomainKeys Identified Mail) is an email authentication method that allows the sender to attach a digital signature to emails. This signature is used to verify that the email was indeed sent by the owner of the domain and that the message was not altered during transmission. DKIM helps improve email security by preventing email […]

Distance Vector Routing Protocols determine the best path to a destination based on hop count and periodically share routing information with neighboring routers. These protocols use the Bellman-Ford algorithm to calculate routes and rely on routers exchanging their entire routing tables at regular intervals. Distance Vector protocols are simpler to configure but converge more slowly […]
