Endpoint Detection and Response (EDR) refers to an approach to security that continuously monitors, detects, and analyzes the activities and events on endpoints, such as individual computers, laptops, servers, and mobile devices, to identify and respond to potential security threats.

Endpoint Security refers to protecting individual devices (endpoints) such as computers, laptops, mobile devices, and servers against a wide variety of security risks and threats. The goal of endpoint security is to protect these devices against potential attacks, data leaks, malware infections and other forms of cyber threats.

The General Data Protection Regulation (GDPR) is an European privacy law that came into effect on May 25, 2018. The GDPR is designed to give individuals more control over their personal data and to regulate and harmonize the way organizations process and protect personal data.

"Immediate Threat Intelligence" (ITI) refers to real-time information and data that identifies and reports immediate threats, attacks or risks. It is a type of cyber threat intelligence (CTI) that focuses on detecting and responding to current and immediate cyber threats.

Malware is short for "malicious software" and is also referred to as "malicious software". It is software designed to harm computer systems, networks or mobile devices and can take various forms, such as viruses, trojans, spyware, ransomware and adware.

Managed Detection and Response (MDR) is a comprehensive cybersecurity service provided by specialist security companies. It focuses on detecting, investigating and responding to advanced cyberthreats and attacks within an organization. MDR goes beyond traditional security solutions by providing active monitoring, analytics and incident response to quickly and effectively respond to threats that might otherwise go undetected.

PII stands for "Personally Identifiable Information" and can be translated as "Personally Identifiable Data".

The Purple Team is a term often used in the cybersecurity world to describe a team that represents both attackers and defenders. The team consists of red team members, who try to penetrate an organization's systems, and blue team members, who try to detect and prevent the attack.

Ransomware is a type of malicious software (malware) that encrypts files on a computer and then demands a ransom from the owner of the computer to unlock the files. This type of malware can be spread through email attachments, hacked websites, infected software or USB sticks.

Ransomware can wreak havoc, especially if it spreads within a network. It can lead to data loss, business process disruption and financial loss. It is therefore important to regularly back up important files and keep up with software updates

Secure Email Gateways (SEGs) are secure email gateways used to scan incoming and outgoing emails for potential threats and ensure secure communications between email users. They are commonly used by organizations to protect their emails from spam, phishing attacks, malware and other forms of cyber threats.

"Security Posture Management" refers to the process of assessing, analyzing and managing an organization's overall security posture and controls. This includes identifying vulnerabilities, evaluating security controls and policies, and taking steps to improve and maintain overall security. The goal of security posture management is to increase an organization's resilience to cyberthreats and maintain a strong security posture.

SIEM stands for Security Information and Event Management, while SOAR stands for Security Orchestration, Automation, and Response. Both processes play an important role in the security of IT systems and networks.

Sigma is an open standard for defining detection rules for security information and event management (SIEM) and security analytics software. Sigma's goal is to provide a common language and syntax that allows security professionals to write detection rules that can be used across different SIEM systems and security tools.

Sigma rules describe patterns and conditions that can indicate potential security threats, such as attacks, intrusion attempts, malware infections, and other malicious activities. These rules are written in human-readable text format and can be interpreted by SIEM systems and other security tools that support Sigma.

A Security Operating Center (SOC) is a central location where security activities and procedures are monitored and controlled to protect an organization's IT infrastructure and data from potential threats. The SOC team works closely with the IT department and other stakeholders to ensure and improve the security of the organization.

A trojan is a type of malware that hides in an innocent program or file. If you open such a program or file, the trojan can cause damage to your computer. For example, a trojan can steal, delete or change data, take over your computer or install other malware. A trojan is not a virus, because a trojan cannot spread itself to other computers. A trojan is often used to create a backdoor in your security, making it easier for hackers to gain access to your system.

Vulnerability management is the process of identifying, analyzing and remediating vulnerabilities in systems, networks and applications. The goal of vulnerability management is to improve the security and resilience of the organization by reducing the risk of cyber-attacks. Vulnerability management includes regularly scanning the IT environment, prioritizing the vulnerabilities found based on their severity and impact, and implementing appropriate measures to fix or mitigate them.

A web application firewall (WAF) is a security solution used to protect web applications against various types of attacks, such as SQL injections, cross-site scripting (XSS), and other exploits that can compromise the application.
