- Topic 1: Security Concepts: This topic explains the CIA triad, security terms, and principles of the defense-in-depth strategy. The topic also compares security deployments, access control models, behavioral and statistical detection, and rule-based detection. Moreover, the topic also delves into sub-topics which point out the challenges of data visibility. Lastly, the topic focuses on identifying potential data loss from traffic profiles.
- Topic 2: Security Monitoring: It identifies the certificate components in a given scenario, describes the impact of certificates on security, and compares attack surface and vulnerability. The topic also focuses on the impact of technologies on data visibility, network attacks, web application attacks, endpoint-based attacks, evasion and obfuscation techniques.
- Topic 3: Host-Based Analysis: This topic explains the functionality of endpoint technologies and the role of attribution in an investigation. It also identifies different components of an operating system and types of evidence used based on provided logs. Explanation of the role of attribution in an investigation, tampered and untampered disk image, and interpretation of operating system, application, or command line logs are also available in this topic.
- Topic 4: Network Intrusion Analysis: Interpretation of basic regular expressions, common artifact elements, and fields in protocol headers is given in this topic. It also identifies key elements in an intrusion from a given PCAP file. Extraction of different files from a TCP stream is also discussed. The topic also compares the characteristics of data obtained from taps or traffic monitoring, and deep packet inspection. Lastly, the topic discusses mapping the events to source technologies.
- Topic 5: Security Policies and Procedures: It describes management concepts, different elements in an incident response plan, and the relationship of SOC metrics to scope analysis. The topic also identifies different elements for network profiling, server profiling, as well as identification of secured data in a network. Application of the incident handling process is also discussed. Lastly, the topic focuses on mapping the organization stakeholders against the NIST IR categories.

A user reports difficulties accessing certain external web pages. When an engineer examines traffic to and from the external domain in full packet captures, they notice that many SYNs have the same sequence number, source, and destination IP address, but they have different payloads. What is causing this situation?
TCP injection is an attack where the attacker sends crafted packets into an existing TCP session. These packets appear to be part of the session.
The presence of many SYN packets with the same sequence number, source, and destination IP but different payloads indicates that an attacker might be injecting packets into the session.
This method can be used to disrupt communication, inject malicious commands, or manipulate the data being transmitted.

Which of these is a defense-in-depth strategy principle?
Defense-in-depth is a layered security strategy that aims to protect information and resources through multiple security measures.
One of its key principles is the concept of least privilege, which means providing users and systems with the minimum level of access necessary to perform their job functions.
By assigning only the necessary permissions, the attack surface is reduced, and the potential damage from a compromised account or system is minimized.
This principle helps in mitigating the risk of unauthorized access and limits the capabilities of an attacker if they gain access to an account.

Which type of data is used to detect anomalies in the network?
Statistical data is crucial for detecting anomalies within a network because it provides a baseline of normal behavior.
Anomaly detection involves comparing current network data against historical statistical data to identify deviations from expected patterns.
This method helps in identifying unusual activities that could signify a security threat, such as unusual login attempts, data transfers, or access patterns.
Statistical data analysis tools use metrics such as mean, variance, and standard deviation to flag anomalies, aiding in proactive threat detection.

How low does rule-based detection differ from behavioral detection?
Rule-based detection systems operate using predefined patterns and signatures to identify known threats. These patterns are based on prior knowledge of attack methods and vulnerabilities.
Behavioral detection systems, on the other hand, analyze the normal behavior of a network or system to establish a baseline. They then monitor for deviations from this baseline, which may indicate potential threats.
Rule-based systems are effective at detecting known threats but may struggle with novel or zero-day attacks that do not match existing signatures.
Behavioral systems can detect unknown threats by recognizing abnormal activities, making them useful in identifying zero-day exploits and other sophisticated attacks.
