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.
