IDSGAN: Generative Adversarial Networks for Attack Generation against Intrusion Detection
As an important tool in security, the intrusion detection system bears the
responsibility of the defense to network attacks performed by malicious
traffic. Nowadays, with the help of machine learning algorithms, the intrusion
detection system develops rapidly. However, the robustness of this system is
questionable when it faces the adversarial attacks. To improve the detection
system, more potential attack approaches should be researched. In this paper, a
framework of the generative adversarial networks, IDSGAN, is proposed to
generate the adversarial attacks, which can deceive and evade the intrusion
detection system. Considering that the internal structure of the detection
system is unknown to attackers, adversarial attack examples perform the
black-box attacks against the detection system. IDSGAN leverages a generator to
transform original malicious traffic into adversarial malicious traffic. A
discriminator classifies traffic examples and simulates the black-box detection
system. More significantly, we only modify part of the attacks' nonfunctional
features to guarantee the validity of the intrusion. Based on the dataset
NSL-KDD, the feasibility of the model is demonstrated to attack many detection
systems with different attacks and the excellent results are achieved.
Moreover, the robustness of IDSGAN is verified by changing the amount of the
unmodified features.Comment: 8 pages, 5 figure
Ion-mediated RNA structural collapse: effect of spatial confinement
RNAs are negatively charged molecules residing in macromolecular crowding
cellular environments. Macromolecular confinement can influence the ion effects
in RNA folding. In this work, using the recently developed tightly bound ion
model for ion fluctuation and correlation, we investigate the confinement
effect on the ion-mediated RNA structural collapse for a simple model system.
We found that, for both Na and Mg, ion efficiencies in mediating
structural collapse/folding are significantly enhanced by the structural
confinement. Such an enhancement in the ion efficiency is attributed to the
decreased electrostatic free energy difference between the compact conformation
ensemble and the (restricted) extended conformation ensemble due to the spatial
restriction.Comment: 22 pages, 5 figure
