A multiagent based strategy for detecting attacks in databases in a distributed mode

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 to the classifier agents with a great capacity of learning and adaptation to face this type of attack. The architecture combines strategies of intrusion detection systems such as misuse detection and anomaly detection. It has been tested and the results are presented in this paper.

Outpatient follow-up during the first year after heart transplantation, is it feasible?

First year follow-up after heart transplantation requires invasive tests. Although patients used to be hospitalized for this purpose, ambulatory invasive procedures now offer the possibility of outpatient follow-up. The feasibility and security of this strategy is unknown. From 2007 we transitioned to outpatient follow-up. We have retrospectively reviewed the clinical course of the outpatient group (2007 to 2014) and an inpatient group (2000–2006). Basal characteristics, hospital stay, infections, rejection episodes and vascular complications were evaluated. 87 patients had Inpatient Follow-up (IF) and 98 Outpatient Follow-up (OF). Basal characteristics were similar, with significant differences in immunosuppression (tacrolimus IF 44.8% vs. OF 90.8%, and mycophenolate IF 86.2% vs OF 100%, both p values < 0.001) and age (IF 52 ± 11.5 years vs. OF 56.1 ± 11 years, p = 0.016). In the OF group more clinical visits were performed (IF 10 vs. OF 13, p < 0.001) while hospital stay was lower (IF 23 days vs. OF 3 days, p < 0.001). The rate of infection, rejection, and vascular complications was similar. No difference was found in 1-year mortality (IF 2.3% vs. 1.0%, p = 0.60). First year post-cardiac transplantation outpatient follow-up seems to be feasible and safe in terms of infection, rejection, vascular complications and mortality.
