Simple packet filters are becoming a thing of the past. Even the open-source domain is moving towards Next-Generation Firewalls. OPNsense is a top player when it comes to intrusion detection, application control, web filtering, and Antivirus.No network is too insignificant to be spared by an attacker. Even home networks, washing machines, and smartwatches are under threat and require a secure environment.Firewalls are a component of the security concept. They protect against known and emerging threats to computers and networks. A firewall offers the highest level of protection if its functions are known, its operation is simple, and it is ideally positioned in the surrounding infrastructure.OPNsense accepts the challenge and meets these criteria in a number of ways. This book is the ideal companion for understanding, installing, and setting up an OPNsense firewall.Each chapter explains a real-world situation, describes the theoretical fundamentals, and presents a lab experiment for better understanding. Finally, it offers a solution using OPNsense methods and knowledge with a technical standpoint.The chapters are mostly independent of each other, however, they do increase in competency level. The topics covered are appropriate for beginners and professionals. Major topics include: - Installation of OPNsense on physical hardware, VMware or VirtualBox- Initial setup- Updates and configuration- IPv6 - Transparent firewall- Address translation (NAT)- Management interface- IPsec and OpenVPN- Web Proxy- Authentication- Multi-WAN- Intrusion Detection- High Availability- API- Performance Tuning [more]

Simple Paketfilter waren gestern. Selbst im Open-Source-Bereich sind die Next-Generation Firewalls angekommen. Und OPNsense mischt ganz vorn mit, wenn es um Einbruchserkennung, Applikationskontrolle, Web-Filter oder Antivirus geht.Denn kein Netz ist zu unbedeutend, um nicht angegriffen zu werden. Selbst Heimnetze, Armbanduhren und Lichtschalter sind bedroht und erwarten eine sichere Umgebung.Eine Firewall ist ein Baustein im Sicherheitskonzept. Sie schützt vor bekannten und neuen Gefahren für Computer und Netzwerke. Den besten Schutz bietet eine Firewall, wenn ihre Funktionen bekannt sind, sie einfach zu bedienen ist und sie optimal in die umgebende Infrastruktur integriert ist.OPNsense stellt sich dieser Herausforderung und erfüllt die Kriterien auf unterschiedliche Weise. Dieses Buch ist der ideale Begleiter, um OPNsense zu verstehen, zu installieren und zu konfigurieren.Jedes Kapitel erläutert eine Problemsituation, beschreibt die theoretischen Grundlagen und stellt ein Laborexperiment zum Nachahmung vor. Abschließend zeigt es den Lösungsansatz mit Methoden von OPNsense und die technischen Hintergründe.Die Kapitel sind weitgehend unabhängig voneinander, steigern sich aber in ihrem Niveau. So sind die Themen geeignet vom Einsteiger bis zum Profi. Aus dem Inhalt:- Installation von OPNsense auf echter Hardware, VMware oder VirtualBox- Ersteinrichtung- Updates und Konfiguration- IPv6 - Transparente Firewall- Adressumsetzung (NAT)- Management Interface- IPsec und OpenVPN- Web-Proxy- Authentifizierung- Multi-WAN- Intrusion Detection- Hochverfügbarkeit- Programmierschnittstelle- Leistungssteigerung [more]

Ethical hacking, also known as penetration testing or white-hat hacking, is a practice of deliberately probing and assessing the security of computer systems, networks, applications, and other digital environments in order to identify vulnerabilities and weaknesses that could potentially be exploited by malicious hackers. The primary goal of ethical hacking is to proactively uncover these vulnerabilities before they can be exploited by unauthorized individuals or groups, thereby helping organizations strengthen their security measures and protect their sensitive information. Key aspects of ethical hacking include: Authorization: Ethical hackers must obtain proper authorization from the owner or administrator of the system before conducting any tests. This ensures that the testing process remains within legal and ethical boundaries. Methodology: Ethical hacking involves a systematic and structured approach to identify vulnerabilities. This includes various techniques like network scanning, penetration testing, social engineering, and vulnerability assessment. Scope: The scope of an ethical hacking engagement is defined before the testing begins. It outlines the systems, applications, and networks that will be tested. Staying within the defined scope ensures that only authorized systems are tested. Information Gathering: Ethical hackers gather information about the target systems, including their architecture, software versions, and potential weak points. This information helps them plan their testing approach. Vulnerability Analysis: Ethical hackers use various tools and techniques to identify vulnerabilities, misconfigurations, and weak points in the target systems. These vulnerabilities could include software bugs, insecure configurations, or design flaws. Exploitation: In a controlled environment, ethical hackers might attempt to exploit the identified vulnerabilities to demonstrate the potential impact of a real attack. However, they stop short of causing [more]
