An Intrusion Prevention System (IPS) is a network security technology designed to monitor network traffic for signs of malicious activity and automatically block or mitigate potential threats in real time. Unlike an Intrusion Detection System (IDS), which only detects and alerts on suspicious activity, an IPS takes a more proactive approach by intercepting and stopping […]

Classless Inter-Domain Routing (CIDR) is an IP addressing method that improves efficiency by allowing flexible subnetting and aggregation of IP addresses. Unlike traditional class-based addressing, CIDR uses prefix notation (e.g., 192.168.1.0/24), where the number after the slash represents the bits used for the network portion. This allows for precise allocation of IP addresses, reducing wastage […]

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) […]

ISACA (Information Systems Audit and Control Association) is a global professional association that focuses on IT governance, risk management, cybersecurity, and audit. It provides a range of certifications, such as CISA (Certified Information Systems Auditor) and CISM (Certified Information Security Manager), to help professionals advance their careers in IT and cybersecurity. ISACA also offers frameworks, […]

A CIRT (Cybersecurity Incident Response Team) is a specialized group within an organization responsible for identifying, managing, and responding to cybersecurity incidents. Their goal is to minimize the impact of incidents like data breaches, malware infections, or denial-of-service attacks by following a structured incident response plan. CIRT also focuses on post-incident analysis to improve future […]

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

The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) provide best practices and guidelines for Information Security Management Systems (ISMS). These standards are designed to help organizations mitigate risks across the three core pillars of information security: People, Processes, and Technology. By following these guidelines, organizations can ensure a comprehensive approach to […]

Control Objectives for Information and Related Technologies (COBIT) is a framework created by ISACA (Information Systems Audit and Control Association) that provides a comprehensive governance and management structure for enterprise IT. COBIT helps organizations ensure effective management and control of information technology by offering a set of best practices, principles, and guidelines for IT governance […]

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

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 […]
