One significant security risk for VLAN trunking is the possibility of VLAN hopping attacks, where an attacker can send packets to a VLAN they do not belong to by manipulating the trunking protocol. This can happen through techniques like double tagging, where the attacker places a packet with two VLAN tags, allowing it to traverse trunk links and reach unauthorized VLANs. Proper configuration of VLANs, including using dynamic trunking protocols securely and implementing access control lists, is essential to mitigate these risks.

Layer 2 security best practices would help prevent VLAN hopping attacks?
To prevent VLAN hopping attacks, it is essential to implement best practices such as disabling unused switch ports and setting them to an "inactive" state. Additionally, configuring VLAN trunking protocols properly and using port security to limit the number of MAC addresses per port can significantly reduce the risk. Implementing Access Control Lists (ACLs) to restrict traffic between VLANs and ensuring that dynamic trunking protocol (DTP) is disabled on trunk ports further enhances security. Regularly monitoring network traffic for anomalies can also help detect and mitigate potential VLAN hopping attempts.
What is virtual trunking protocol VTP?
Virtual Trunking Protocol (VTP) is a Cisco proprietary protocol used in switched networks to manage VLAN configurations across multiple switches. It allows switches to share VLAN information, ensuring consistency in VLAN configuration throughout the network. VTP reduces the need for manual VLAN configuration on each switch, thereby simplifying network management and reducing the risk of errors. It operates in different modes, including server, client, and transparent, each with specific roles in VLAN information dissemination.
How does VTP affect VLAN administration?
VLAN Trunking Protocol (VTP) simplifies VLAN administration by allowing network administrators to manage VLAN configurations centrally across multiple switches. When a change is made to VLANs on one switch, VTP propagates this information to all other switches in the VTP domain, ensuring consistency and reducing the risk of configuration errors. This centralized management streamlines the process of adding, deleting, or modifying VLANs, enhancing overall network efficiency. However, it also necessitates careful management to avoid unintentional VLAN deletions or misconfigurations.

Which of the following is NOT considered a risk factor considering that wearing PPE can put the responder at considerable risk both physically and psychologically?
Complacency is NOT considered a risk factor in this context. Other risk factors include lack of proper training, inadequate PPE, and exposure to hazardous materials. Complacency may lead to a false sense of security and reduce vigilance during response efforts.

Why Separators are provided in compartmental trunking to?
Separators are provided in compartmental trunking to create distinct pathways for different types of services, such as electrical, data, and telecommunications, ensuring that they do not interfere with each other. This segregation helps to maintain system integrity and performance, reduces the risk of electromagnetic interference, and enhances safety by preventing potential hazards. Additionally, it facilitates easier installation, maintenance, and future upgrades of the services within the trunking system.
How interpret the market risk of a security?
a security's risk is divided into systematic (Market risk) and Unsystematic risk (Diversifiable risk), the market risk is the risk inherent to the security, it is attributed to macro economic factors such as inflation, war etc. and affects all securities in the market and so cannot be diversified away. Market risk of a security is measured and reflected by the Beta coefficientwhich is an index that measures the security's volatility to market movements i.e. how much the returns of the security will vary if their changes in the market
Is the so what factor of risk assessment in opsec?
The "so what" factor in risk assessment for operational security (OpSec) refers to the importance of understanding the implications of identified risks. It emphasizes evaluating how vulnerabilities could potentially impact an organization's operations, reputation, or security. By addressing the "so what," decision-makers can prioritize risks based on their potential consequences and allocate resources effectively to mitigate them. This ensures that OpSec strategies are aligned with the organization's overall objectives and risk tolerance.
