    Study Notes

    High-Availability Network Security

    • A high-availability network should have processes and tools for risk assessment, threat intelligence, vulnerability scanning, and penetration testing to identify and mitigate weaknesses or gaps in network security.

    Bastion Host

    • A bastion host is a special-purpose server designed to withstand attacks and provide secure access to internal resources.
    • A bastion host is usually placed on the edge of a network, acting as a gateway or proxy to the internal network.
    • A bastion host can be configured to allow only certain types of traffic and block all others.
    • A bastion host can run security software such as firewalls, intrusion detection systems, and antivirus programs to monitor and filter incoming and outgoing traffic.

    Incident Response Activities

    • Analysis is the incident response activity that involves understanding the source of an incident.
    • Analysis involves collecting and examining evidence, identifying the root cause, determining the scope and impact, and assessing the threat actor's motives and capabilities.

    Automation

    • Automation is the best way to consistently determine on a daily basis whether security settings on servers have been modified.
    • Automation is the process of using software, hardware, or other tools to perform tasks that would otherwise require human intervention or manual effort.
    • Automation can help to improve the efficiency, accuracy, and consistency of security operations, as well as reduce human errors and costs.

    Compensating Control

    • A compensating control is a security measure that is implemented to mitigate the risk of a vulnerability or weakness that cannot be resolved by the primary control.
    • A compensating control does not prevent or eliminate the vulnerability or weakness, but it can reduce the likelihood or impact of an attack.

    Disaster Recovery Plan

    • A disaster recovery plan (DRP) is a set of policies and procedures that aim to restore the normal operations of an organization in the event of a system failure, natural disaster, or other emergency.

    Security Awareness Program

    • A training curriculum plan for a security awareness program should address the threat vectors based on the industry in which the organization operates.
    • A training curriculum plan for a security awareness program should also address the cadence and duration of training events.

    Risk Register

    • A risk register is a document that records and tracks the risks associated with a project, system, or organization.
    • A risk register typically includes information such as the risk description, the risk owner, the risk probability, the risk impact, the risk level, the risk response strategy, and the risk status.
