Seguridad y alta disponibilidad | Raquel Castellanos Crespo Instalación y configuración de cortafuegos Seguridad y alta disponibilidad Raquel Castellanos Crespo Concepto y utilización de cortafuegos Un cortafuegos (firewall en inglés) es una parte de un sistema o una red que está diseñada para bloquear el acceso no autorizado, permitiendo al mismo tiempo comunicaciones autorizadas. Se trata de un dispositivo o conjunto de dispositivos configurados para permitir, limitar, cifrar, descifrar, el tráfico entre los diferentes ámbitos sobre la base de un conjunto de normas y otros criterios. Los cortafuegos pueden ser implementados en hardware o software, o una combinación de ambos. Los cortafuegos se utilizan con frecuencia para evitar que los usuarios de Internet no autorizados tengan acceso a redes privadas conectadas a Internet, especialmente intranets. Todos los mensajes que entren o salgan de la intranet pasan a través del cortafuegos, que examina cada mensaje y bloquea aquellos que no cumplen los criterios de seguridad especificados. -

Architecture of a Identity Based Firewall System
ARCHITECTURE OF A IDENTITY BASED FIREWALL SYSTEM Nenad Stojanovski1 and Marjan Gušev2 1 Makedonski Telekom AD, Orce Nikolov BB, 1000 Skopje, Macedonia [email protected] 2 Faculty of Natural Sciences and Mathematics, Ss. Cyril and Methodius University, Arhimedova b.b., PO Box 162, 1000 Skopje, Macedonia [email protected] ABSTRACT Classic firewall systems are built to filter traffic based on IP addresses, source and destination ports and protocol types. The modern networks have grown to a level where the possibility for users’ mobility is a must. In such networks, modern firewalls may introduce such complexity where administration can become very frustrating since it needs the intervention of a firewall administrator. The solution for this problem is an identity based firewall system. In this paper we will present a new design of a firewall system that uses the user’s identity to filter the traffic. In the design phase we will define key points which have to be satisfied as a crucial milestone for the functioning of the whole Identity based firewall system. KEYWORDS Identity based firewalls, user identity, firewalls, network security, computer networks, firewall systems design 1. INTRODUCTION Classic firewall systems are built to filter traffic based on source and destination IP addresses, source and destination ports and protocol types[11]. As Information technology moves forward and advances, classic firewalls start to become very robust and unusable when it comes to the transparent user experience. The main problem that arises from using classic firewalls in a modern dynamic environment is that users have to be mobile and have access to their resources. -

Computational Resource Abuse in Web Applications
Computational Resource Abuse in Web Applications Juan David Parra Rodriguez Dissertation eingereicht an der Fakult¨atf¨ur Informatik und Mathematik der Universit¨at Passau zur Erlangung des Grades eines Doktors der Naturwissenschaften A dissertation submitted to the faculty of computer science and mathematics in partial fulfillment of the requirements for the degree of doctor of natural sciences Betreuer: Prof. Dr. rer. nat. Joachim Posegga Passau, Germany, April 2019 Abstract Internet browsers include Application Programming Interfaces (APIs) to support Web applications that require complex functionality, e.g., to let end users watch videos, make phone calls, and play video games. Meanwhile, many Web applications employ the browser APIs to rely on the user's hardware to execute intensive computation, access the Graphics Processing Unit (GPU), use persistent storage, and establish network connections. However, providing access to the system's computational resources, i.e., processing, storage, and networking, through the browser creates an opportunity for attackers to abuse resources. Principally, the problem occurs when an attacker compromises a Web site and includes malicious code to abuse its visitor's computational resources. For example, an attacker can abuse the user's system networking capabilities to perform a Denial of Service (DoS) attack against third parties. What is more, computational resource abuse has not received widespread attention from the Web security community because most of the current specifications are focused on content and session properties such as isolation, confidentiality, and integrity. Our primary goal is to study computational resource abuse and to advance the state of the art by providing a general attacker model, multiple case studies, a thorough anal- ysis of available security mechanisms, and a new detection mechanism. -
