3. What is NIDS?
A Network-based Intrusion Detection System (NIDS) is an intrusion detection system that monitors and examines network traffic to defend a system from network-based threats. Also, it detects malicious activity by identifying anomalies in incoming packets.
4. What is HIDS?
Host-based Intrusion Detection System (HIDS) is an intrusion detection system that monitors and analyzes the computer infrastructure for any suspicious activities as well as the network packets on its network interfaces. It can involve internal misuse of resources or data and external invasions.

Six phases of cyber incident response plan:
- Preparation
- Identification
- Containment
- Eradication
- Recovery
- Lessons learned

Some typical inside threats include:
- Malicious insiders
- Departing personnel
- Negligent employees
- Security evaders
- Inside agents
- Third-party partners
7. What are the best methods for preventing insider threats?
To prevent insider threats, take some of the procedures listed below.

15. What differentiates the NIST and SANS frameworks?
NIST: The NIST framework is one of the most widely used methodologies for comprehending and managing cybersecurity risk. It includes details on how to set up an incident response team, an Incident Response Plan (IRP), a communication plan, and training scenarios. This framework covers the four phases that condense the six phases of incident response:
- Preparation
- Detection and Analysis
- Containment, Eradication, and Recovery
- Post-Incident Activity
SANS: Comparatively to the NIST framework, which has a more comprehensive operational scope, the SANS framework solely focuses on security. This framework includes six phases:
- Preparation
- Identification
- Containment
- Eradication
- Recovery
- Lessons Learned
16. What does OODA stand for?
OODA stands for Observe, Orient, Decide, and Act, is a four-step decision-making process. It is a set of techniques for detecting, investigating, and handling potential security problems in a way that limits incidents and enables speedy recovery in a real-time environment.
17. What is LogRhythm?

- System takeover: A successful phishing attack allows the hacker to install malware and enables them to take over the system.
19. What is an Incident Response Team?
An Incident Response Team is a team who is in charge of organizing and responding to IT incidents, such as cyberattacks, system outages, and data breaches. They are also in charge of creating incident response plans, identifying and fixing system flaws, enforcing security regulations, and assessing best security practices.

Incident Response Teams come in three main categories.
- Computer Security Incident Response Team (CSIRT)
- Computer Emergency Response Team (CERT)
- Security Operations Center (SOC)
