B. Audit findings

D. Staging

Answer DescriptionExplanation: A staging environment is a controlled setting that closely mirrors the production environment but uses a subset of customer data. It is used to test major system upgrades, assess their impact, and demonstrate new features before they are rolled out to the live production environment. This ensures that any issues can be identified and addressed in a safe environment before affecting end-users.

C. Encryption

D. Active

Answer DescriptionExplanation: To block signature-based attacks, the Intrusion Prevention System (IPS) must be in active mode. In this mode, the IPS can actively monitor and block malicious traffic in real time based on predefined signatures. This is the best mode to prevent known attack types from reaching the internal network. Monitor mode and sensor mode are typically passive, meaning they only observe and log traffic without actively blocking it. Audit mode is used for review purposes and does not actively block traffic.

B. Infrastructure as code

Answer DescriptionExplanation: Infrastructure as code (IaC) is a method of using code and automation to manage and provision cloud resources, such as servers, networks, storage, and applications. IaC allows for easy deployment, scalability, consistency, and repeatability of cloud environments. IaC is also a key component of DevSecOps, which integrates security into the development and operations processes.

A. Network

Answer DescriptionExplanation: To determine whether the connection was successful after a user clicked on a link in a phishing email, the most relevant log source to analyze would be the network logs. These logs would provide information on outbound and inbound traffic, allowing the analyst to see if the user’s system connected to the remote server specified in the phishing link. Network logs can include details such as IP addresses, domains accessed, and the success or failure of connections, which are crucial for understanding the impact of the phishing attempt.

B. Containers

Answer DescriptionExplanation: Containers are a method of virtualization that allows applications to run in isolated environments with their own dependencies, libraries, and configurations. Containers are best suited for constantly changing environments because they are lightweight, portable, scalable, and easy to deploy and update. Containers can also support microservices architectures, which enable faster and more frequent delivery of software features.

Answer DescriptionAnswer: See the Explanation part for all the Solution.

Explanation: To configure the site-to-site VPN between the two branch offices according to the provided requirements, here are the detailed steps and settings that need to be applied to the VPN concentrators:
Requirements:
Most secure algorithms should be selected.
All traffic should be encrypted over the VPN.
A secret password will be used to authenticate the two VPN concentrators.
VPN Concentrator 1 Configuration:
Phase 1:
Peer IP address: 5.5.5.10 (The IP address of VPN Concentrator 2)
Auth method: PSK (Pre-Shared Key)
Negotiation mode: MAIN
Encryption algorithm: AES256
Hash algorithm: SHA256
DH key group: 14
Phase 2:
Mode: Tunnel
Protocol: ESP (Encapsulating Security Payload)
Encryption algorithm: AES256
Hash algorithm: SHA256
Local network/mask: 192.168.1.0/24
Remote network/mask: 192.168.2.0/24
VPN Concentrator 2 Configuration:
Phase 1:
Peer IP address: 5.5.5.5 (The IP address of VPN Concentrator 1)
Auth method: PSK (Pre-Shared Key)
Negotiation mode: MAIN
Encryption algorithm: AES256
Hash algorithm: SHA256
DH key group: 14
Phase 2:
Mode: Tunnel
Protocol: ESP (Encapsulating Security Payload)
Encryption algorithm: AES256
Hash algorithm: SHA256
Local network/mask: 192.168.2.0/24
Remote network/mask: 192.168.1.0/24
Summary:
Peer IP Address: Set to the IP address of the remote VPN concentrator.
Auth Method: PSK for using a pre-shared key.
Negotiation Mode: MAIN for the initial setup.
Encryption Algorithm: AES256, which is a strong and secure algorithm.
Hash Algorithm: SHA256, which provides strong hashing.
DH Key Group: 14 for strong Diffie-Hellman key exchange.
Phase 2 Protocol: ESP for encryption and integrity.
Local and Remote Networks: Properly configure the local and remote network addresses to match each branch office subnet.
By configuring these settings on both VPN concentrators, the site-to-site VPN will meet the requirements for strong security algorithms, encryption of all traffic, and authentication using a pre-shared key.
