QUESTION: 17

Identify the UBA tool that collects user activity details from multiple sources and uses artificial intelligence and machine learning algorithms to perform user behavior analysis to prevent and detect various threats before the fraud is perpetrated.

Nmap
ClamWin
Dtex systems
Wireshark

Answer(s): C

Explanation:

Dtex Systems is the UBA tool that collects user activity details from multiple sources and uses artificial intelligence and machine learning algorithms to perform user behavior analysis to prevent and detect various threats before the fraud is perpetrated. Dtex Systems is a user and entity behavior analytics (UEBA) platform that provides visibility, detection, and response capabilities for insider threats, compromised accounts, data loss, and fraud. Dtex Systems collects user activity data from endpoints, servers, cloud applications, and network traffic, and applies advanced analytics and machine learning to establish baselines of normal user behavior, identify anomalies, and assign risk scores. Dtex Systems also provides contextual information, such as user intent, motivation, and sentiment, to help security teams understand and respond to the threats. Dtex Systems can integrate with other security tools, such as SIEM, DLP, or IAM, to enhance the security posture of the organization123.

QUESTION: 18

Below is the list of encryption modes used in a wireless network.
1.WPA2 Enterprise with RADIUS

2.WPA3
3.WPA2 PSK
4.WPA2 Enterprise
Identify the correct order of wireless encryption modes in terms of security from high to low.

2 -- >1 -- >4 -- >3
3 -- >1 -- >4 -- >2
4 -- >2 -- >3 -- >1
4 -- >3 -- >2 -- >1

Answer(s): A

Explanation:

Explore
The correct order of wireless encryption modes in terms of security from high to low is 2 -> 1 -> 4 ->
3. This is based on the following comparison of the wireless encryption modes:
WPA3: WPA3 is the latest and most secure wireless encryption mode, introduced in 2018 as a successor to WPA2. WPA3 uses the AES encryption protocol and provides several security enhancements, such as stronger password protection, individualized encryption, forward secrecy, and protection against brute-force and dictionary attacks. WPA3 also supports two modes: WPA3- Personal and WPA3-Enterprise, which offer different levels of security for home and business networks. WPA3-Personal uses Simultaneous Authentication of Equals (SAE) to replace the Pre- Shared Key (PSK) method and provide more robust password-based authentication. WPA3-Enterprise uses 192-bit cryptographic strength to provide additional protection for sensitive data and networks123.
WPA2 Enterprise with RADIUS: WPA2 Enterprise with RADIUS is a wireless encryption mode that combines the security features of WPA2 Enterprise and the authentication features of RADIUS. WPA2

Enterprise is a mode of WPA2 that uses the AES encryption protocol and provides stronger security than WPA2 Personal, which uses the PSK method. WPA2 Enterprise uses the 802.1X standard to implement Extensible Authentication Protocol (EAP) methods, such as EAP-TLS, EAP-TTLS, or PEAP, to authenticate users and devices before granting access to the network. RADIUS is a protocol that allows a central server to manage authentication, authorization, and accounting for network access. RADIUS can integrate with WPA2 Enterprise to provide centralized and scalable authentication for large and complex networks, such as corporate or campus networks . WPA2 Enterprise: WPA2 Enterprise is a wireless encryption mode that uses the AES encryption protocol and provides stronger security than WPA2 Personal, which uses the PSK method. WPA2 Enterprise uses the 802.1X standard to implement Extensible Authentication Protocol (EAP) methods, such as EAP-TLS, EAP-TTLS, or PEAP, to authenticate users and devices before granting access to the network. WPA2 Enterprise is suitable for business or public networks that require individual and secure authentication for each user or device . WPA2 PSK: WPA2 PSK is a wireless encryption mode that uses the AES encryption protocol and provides better security than WEP or WPA, which use the TKIP encryption protocol. WPA2 PSK uses the Pre-Shared Key (PSK) method, which means that all users and devices share the same password or passphrase to join the network. WPA2 PSK is easy to set up and use, but it has some security drawbacks, such as being vulnerable to brute-force and dictionary attacks, or having the password compromised by a rogue user or device. WPA2 PSK is suitable for home or small networks that do not require individual authentication or advanced security features .

QUESTION: 19

Which of the following IDS components analyzes the traffic and reports if any suspicious activity is detected?

Command console
Network sensor
Database of attack signatures
Response system

Answer(s): B

Explanation:

The IDS component that analyzes the traffic and reports if any suspicious activity is detected is the network sensor. A network sensor is a device or software application that is deployed at a strategic point or points within the network to monitor and capture the network traffic to and from all devices on the network. A network sensor can operate in one of two modes: promiscuous or inline. In promiscuous mode, the network sensor passively listens to the network traffic and copies the packets for analysis. In inline mode, the network sensor actively intercepts and filters the network traffic and can block or modify the packets based on predefined rules. A network sensor analyzes the network traffic using various detection methods, such as signature-based, anomaly-based, or reputation-based, and compares the traffic patterns with a database of attack signatures or a model of normal behavior. If the network sensor detects any suspicious or malicious activity, such as a reconnaissance scan, an unauthorized access attempt, or a denial-of-service attack, it generates an alert and reports it to the IDS manager or the operator. A network sensor can also integrate with a response system to take appropriate actions, such as logging, notifying, or blocking, in response to the detected activity123.

QUESTION: 20

Which of the following objects of the container network model (CNM) contains the configuration files of a container's network stack, such as routing table, container's interfaces, and DNS settings?

Endpoint
Sandbox
Network drivers
IPAM drivers

Answer(s): B

Explanation:

The object of the container network model (CNM) that contains the configuration files of a container's network stack, such as routing table, container's interfaces, and DNS settings, is the Sandbox. A Sandbox is a logical entity that encapsulates the network configuration and state of a container. A Sandbox can contain one or more endpoints from different networks, and provides isolation and security for the container's network stack. A Sandbox can be implemented using various technologies, such as Linux network namespaces, FreeBSD jails, or Windows compartments. A Sandbox allows the container to have its own view and control of the network resources, such as interfaces, addresses, routes, and DNS settings123.
