Understanding Deception01:14

Understanding Deception

181
Deception is a pervasive aspect of human communication. Empirical studies have shown that most individuals engage in some form of deceit on a daily basis, with approximately 20% of social exchanges involving deceptive elements. Lying follows a developmental trajectory, peaking during adolescence and declining with age, possibly due to the maturation of cognitive control and social accountability.Cognitive and Social Factors in Deception DetectionDespite its prevalence, accurately detecting...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

9.9K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

15.1K
Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the  phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and...

Network Function of a Circuit01:25

Network Function of a Circuit

909
Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

Pilot and Numeric Relaying01:21

Pilot and Numeric Relaying

496
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

Distribution Reliability and Automation01:25

Distribution Reliability and Automation

522
Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Area of Science:

  • Computer Science
  • Network Security
  • Cybersecurity

Background:

  • Penetration attacks pose significant network security threats.
  • Current network defense technologies struggle to fully prevent intruder actions.
  • There is a need for advanced network defense mechanisms.

Purpose of the Study:

  • To propose a novel decoy chain deployment (DCD) method for enhanced network security.
  • To address the limitations of existing defenses against sophisticated network attacks.
  • To improve the resilience of networks against penetration attempts.

Main Methods:

  • Developed a decoy chain deployment (DCD) method leveraging Software-Defined Networking (SDN) and Network Functions Virtualization (NFV).
  • The DCD method considers network security status and resource constraints for decoy chain placement.
  • The approach modifies the network's attack surface to confuse intruders.

Main Results:

  • Simulation experiments demonstrate the effectiveness of the DCD method.
  • The DCD approach significantly increases the time and complexity required for penetration attacks.
  • The proposed method enhances the network's ability to resist intrusion behaviors.

Conclusions:

  • The DCD method offers a robust solution for defending against network penetration attacks.
  • Integrating SDN and NFV provides a flexible and efficient framework for deploying decoys.
  • This strategy effectively deters intruders by obfuscating the network's true state and increasing operational costs.
