Management Ubiquitous of Messages and Documents Organizational through Intelligent Agents
Pinzón Trejos, Cristian; Sánchez, Juan; Cano, Rosa (2009-07-01)In the context of artificial intelligence, the multiagent systems are an alternative solution to address complex problems and distributed. PAINALLI is an multi-agent architecture for managing messages and documents ... -
Mathematical model for a temporal-bounded classifier in security environments
Pinzón Trejos, Cristian; De Paz, Juan; Navarro, Martí; Julián, Vicente; Tapia, Dante; Bajo, Javier (08/01/2012)Security is a major concern when web applications are implemented. This has led to the proposal of a variety of specifications and approaches to provide the necessary security for these environments. SQL injection attacks ... -
Mitigation of the ground reflection effect in real-time locating systems based on wireless sensor networks by using artificial neural networks
Pinzón Trejos, Cristian; Tapia, Dante; De Paz, Juan; Alonso, Ricardo; Pinzón, Cristian; Bajo, Javier; Corchado, Juan (01/01/2013)Wireless sensor networks (WSNs) have become much more relevant in recent years, mainly because they can be used in a wide diversity of applications. Real-time locating systems (RTLSs) are one of the most promising applications ... -
Multi-layer perceptrons to reduce ground reflection effect in real-time locating systems

Indoor Real-Time Locating Systems based on ... -
A Multiagent Based Strategy for Detecting Attacks in Databases in a Distributed Mode
Pinzón Trejos, Cristian; De Paz, Yanira; Bajo, Javier (2009-07-01)This paper presents a distributed hierarchical multiagent architecture for detecting SQL injection attacks against databases. It uses a novel strategy, which is supported by a Case-Based Reasoning mechanism, which provides ... -
A Multiagent Solution to Adaptively Classify SOAP Message and Protect against DoS Attack
Pinzón Trejos, Cristian; De Paz, Juan; Bajo, Javier; Corchado, Juan (11/09/2009)SOAP messages use XML code, which makes them vulnerable to denial of service (DoS) attacks and puts the availability of web services at risk. This article presents an adaptive solution for dealing with DoS attacks in web ... -
Protecting Web Services against DoS Attacks: A Case-Based Reasoning Approach
Pinzón Trejos, Cristian; De Paz, Juan; Zato, Carolina; Peréz, Javier (06/23/2010)The real-time detection is a key factor to detect and block DoS attacks within Web services. DoS attacks can be generated for different techniques that take advantage of points vulnerable within Web services. This paper ... -
Real-time CBR-agent with a mixture of experts in the reuse stage to classify and detect DoS attacks
Pinzón Trejos, Cristian; De Paz, Juan; Navarro, Martí; Bajo, Javier; Julián, Vicente; Corchado, Juan (10/01/2010)Security is a major concern when service environments are implemented. This has led to the proposal of a variety of specifications and proposals based on soft computing methods to provide the necessary security for these ... -
S-MAS: An adaptive hierarchical distributed multi-agent architecture for blocking malicious SOAP messages within Web Services environments
Pinzón Trejos, Cristian; Bajo, Javier; De Paz, Juan; Corchado, Juan (05/01/2011)During the last years the use of Web Service-based applications has notably increased. However, the security has not evolved proportionally, which makes these applications vulnerable and objective of attacks. One of the ... -
SCMAS: A distributed hierarchical multi-agent architecture for blocking attacks to databases
Pinzón Trejos, Cristian; Corchado, Juan; Bajo, Javier; De Paz, Yanira; Perez-Lancho, Belen (04/04/2010)One of the main attacks on databases is the SQL injection attack which causes severe damage both in the commercial aspect and the confidence of users. This paper presents a novel strategy for detecting and preventing SQL ... -
A Security Proposal Based on a Real Time Agent to Protect Web Services Against DoS Attack
Pinzón Trejos, Cristian; González, Angélica; Rubio, Manuel; Bajo, Javier (2012-07-02)This paper describes a novel proposal based on a real time agent to detect and block denial of service attacks within web services environments. The real time agent incorporates a classification mechanism based on a Case-Base ... -
