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. -

A Brief Study and Comparison Of, Open Source Intrusion Detection System Tools
International Journal of Advanced Computational Engineering and Networking, ISSN: 2320-2106, Volume-1, Issue-10, Dec-2013 A BRIEF STUDY AND COMPARISON OF, OPEN SOURCE INTRUSION DETECTION SYSTEM TOOLS 1SURYA BHAGAVAN AMBATI, 2DEEPTI VIDYARTHI 1,2Defence Institute of Advanced Technology (DU) Pune –411025 Email: [email protected], [email protected] Abstract - As the world becomes more connected to the cyber world, attackers and hackers are becoming increasingly sophisticated to penetrate computer systems and networks. Intrusion Detection System (IDS) plays a vital role in defending a network against intrusion. Many commercial IDSs are available in marketplace but with high cost. At the same time open source IDSs are also available with continuous support and upgradation from large user community. Each of these IDSs adopts a different approaches thus may target different applications. This paper provides a quick review of six Open Source IDS tools so that one can choose the appropriate Open Source IDS tool as per their organization requirements. Keywords - Intrusion Detection, Open Source IDS, Network Securit, HIDS, NIDS. I. INTRODUCTION concentrate on the activities in a host without considering the activities in the computer networks. Every day, intruders are invading countless homes On the other hand, NIDS put its focus on computer and organisations across the country via virus, networks without examining the hosts’ activities. worms, Trojans, DoS/DDoS attacks by inserting bits Intrusion Detection methodologies can be classified of malicious code. Intrusion detection system tools as Signature based detection, Anomaly based helps in protecting computer and network from a detection and Stateful Protocol analysis based numerous threats and attacks. -

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. -

National Science Foundation Award #1826994 https://epoc.global Science DMZ as Security Architecture • Allows for better segmentation of risks, more granular application of controls to those segmented risks. • Limit risk profile for high-performance data transfer applications • Apply specific controls to data transfer hosts • Avoid including unnecessary risks, unnecessary controls • Remove degrees of freedom – focus only on what is necessary • Easier to secure • Easier to achieve performance • Easier to troubleshoot Science DMZ Security • Goal : Disentangle security policy and enforcement for science flows from security for business systems • Rationale • Science data traffic is simple from a security perspective • Narrow application set on Science DMZ • Data transfer, data streaming packages • No printers, document readers, web browsers, building control systems, financial databases, staff desktops, etc. • Security controls that are typically implemented to protect business resources often cause performance problems • Separation allows each to be optimized Performance is a Core Requirement •Core information security principles • Confidentiality, Integrity, Availability (CIA) •In data-intensive science, performance is an additional core mission requirement: CIA PICA • CIA principles are important, but if the performance isn’t there the science mission fails • This isn’t about “how much” security you have, but how the security is implemented • Need to appropriately secure systems without performance compromises Motivations • The big myth: The main goal of the Science DMZ is to avoid firewalls and other security controls. -
