SPF (Sender Policy Framework) is an email authentication protocol designed to detect email spoofing (when a sender’s address is forged) and help ensure that an email message was sent from an authorized mail server. SPF works by allowing a domain owner to specify which IP addresses or mail servers are allowed to send emails on […]

Server Message Block (SMB) is a network file-sharing protocol that allows computers to share files, printers, and other resources over a network. Primarily used in Windows environments, SMB enables applications and users to access remote files as if they were local. It operates over TCP port 445 and supports features like authentication, encryption, and session […]

Secure Access Service Edge (SASE) is a cloud-based security architecture that combines networking and security functions into a unified platform. It integrates features such as secure web gateways, firewall-as-a-service, zero trust network access (ZTNA), and SD-WAN to provide secure, efficient, and scalable access to applications and data, regardless of user location. SASE is designed to […]

The SANS Institute is a global leader in cybersecurity training and certification. It offers a wide range of courses, certifications, and resources to help professionals develop expertise in areas such as information security, incident response, and penetration testing. SANS is renowned for its practical, hands-on training and its GIAC (Global Information Assurance Certification) program, which […]

SAN (Storage Area Network) is a high-performance, specialized network designed to provide block-level data storage. It connects servers and storage devices (such as disk arrays or tape libraries) to enable faster, centralized access to storage resources, separate from the regular LAN (Local Area Network) traffic. SANs are typically used in environments where large amounts of […]

A rollback capability refers to the ability to revert a system or database to a previous state.

The Windows Registry is a hierarchical database used by Microsoft Windows to store and manage configuration settings for the operating system, applications, hardware, and user preferences. It consists of keys and values that control system behavior, startup programs, installed software, driver settings, and security policies. The registry is divided into several hives (e.g., HKEY_LOCAL_MACHINE, HKEY_CURRENT_USER), […]

RDP (Remote Desktop Protocol) enables secure remote access to Windows desktops and servers over a network connection. It allows IT administrators and users to view and control remote systems as if they were local. MSPs rely on RDP to manage client systems, perform maintenance, and provide end-user support securely and efficiently. Learn more: https://en.wikipedia.org/wiki/Remote_Desktop_Protocol

QoS (Quality of Service) manages network resources by prioritizing specific types of traffic — for example, giving VoIP or video conferencing packets precedence over general web traffic. MSPs configure QoS to ensure stable call quality, reduce lag, and maintain performance consistency across business networks, especially when bandwidth is limited.

Kerberos is a network authentication protocol that uses ticket-based authentication to securely verify users and services in a network. Developed by MIT, it is widely used in Windows Active Directory (AD) and Unix/Linux environments. Kerberos operates on the basis of a trusted third party, known as the Key Distribution Center (KDC), which issues encrypted tickets […]
