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 […]

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 […]
Read MoreBuffer Overflow Attack
A buffer overflow attack is a type of cyberattack that occurs when a program writes more data into a buffer (a temporary storage area in memory) than it can hold, causing adjacent memory locations to be overwritten. This can lead to unpredictable behavior, crashes, or the execution of malicious code. Attackers exploit buffer overflows by […]
Read MoreBrute-Force Attack
A Brute Force Attack is a cyberattack method where an attacker systematically tries all possible combinations of usernames, passwords, or encryption keys to gain unauthorized access to a system. This attack relies on computing power and time rather than exploiting software vulnerabilities. Common types include dictionary attacks (using predefined wordlists), credential stuffing (using leaked credentials), […]
Read MoreBrute Force
A brute force attack is a trial-and-error method used by attackers to crack passwords, encryption keys, or login credentials by systematically trying every possible combination until the correct one is found. This type of attack can target user accounts, databases, SSH services, and encrypted files. Learn more: https://en.wikipedia.org/wiki/Brute_Force

A BPDU (Bridge Protocol Data Unit) is a control message used by the Spanning Tree Protocol (STP) and its variants (RSTP, MSTP) to prevent Layer 2 network loops in Ethernet switching environments. BPDUs are exchanged between switches to detect network topology changes, elect a root bridge, and maintain a loop-free topology. Learn more: https://en.wikipedia.org/wiki/BPDU

BIMI is an email security standard that allows brands to display their logo next to authenticated emails in the recipient’s inbox. It enhances email security by ensuring that only legitimate emails from verified senders are displayed, helping to build trust and combat phishing attacks.

Border Gateway Protocol (BGP) is the routing protocol of the internet, used to exchange routes between different networks (Autonomous Systems – ASes). It helps routers decide the best path for data to travel across the internet based on policies and path attributes, not just shortest distance. BGP is essential for internet providers, large enterprises, and […]
