The Spindle Assembly Checkpoint02:19

The Spindle Assembly Checkpoint

4.0K
The spindle assembly checkpoint is a molecular surveillance mechanism ensuring the fidelity of chromosome segregation during anaphase. The checkpoint monitors the completion of all the prerequisite steps before chromosome segregation to determine whether the segregation process should proceed or be delayed.
Many proteins function together to control the spindle assembly checkpoint. Mutations affecting these proteins may allow cells to proceed into anaphase prematurely, resulting in the...

Stereotype Content Model02:16

Stereotype Content Model

15.7K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Area of Science:

  • Computer Science
  • Network Security
  • Telecommunications Engineering

Background:

  • Software-Defined Networking-based Mobile Networks (SDN-MNs) are pivotal for 5G architecture.
  • Evolving cyber threats necessitate robust security assessments in network management.
  • Traditional security assessment methods are inadequate for the dynamic and complex nature of SDN-MNs.

Purpose of the Study:

  • To propose an effective security assessment mechanism tailored for SDN-MNs.
  • To address the challenges posed by the diversity and complexity of SDN-MNs in security evaluations.
  • To develop a quantifiable method for assessing the security levels of SDN-MNs.

Main Methods:

  • A novel methodology combining attack graphs and Analytic Hierarchy Process (AHP) is proposed.
  • A new attack graph definition and generation algorithm are introduced to handle SDN-MN complexity.
  • Node Minimal Effort (NME) is defined to quantify attack costs, and AHP integrated with TOPSIS is used to calculate NME, considering dynamic factors.

Main Results:

  • The proposed methodology effectively assesses the security of SDN-MNs.
  • The novel attack graph generation algorithm addresses the diversity and complexity of these networks.
  • The case study validates the proposed mechanism, demonstrating its advantages in quantifying security levels.

Conclusions:

  • The developed security assessment mechanism provides an effective solution for SDN-MNs.
  • The integration of attack graphs, AHP, and TOPSIS offers a robust approach to network security evaluation.
  • The methodology enhances the security posture of future 5G mobile networks.
