A Trojan malware attack is a type of malicious code or software that disguises itself as a legitimate program or file to trick users into executing it. Once executed, the Trojan can perform various harmful actions on the infected system or network, such as stealing data, deleting files, or installing other malware. There are different types of Trojan malware attacks, depending on their purpose and behavior. Two common types are:

• Rootkit: A rootkit is a type of Trojan that hides itself and other malware from detection and removal by antivirus software or system tools. A rootkit can modify the operating system or the firmware of the device to gain persistent and privileged access to the system. A rootkit can also intercept and manipulate system calls, network traffic, or user input to conceal its activities or redirect them to malicious servers.
• Backdoor: A backdoor is a type of Trojan that creates a secret or unauthorized access point to the infected system or network. A backdoor can allow an attacker to remotely control the system, execute commands, upload or download files, or monitor the system activity. A backdoor can also be used to install other malware or launch further attacks on other systems or networks.

Device compliance is the state of devices meeting the standards and regulations for the industry or organization. Device compliance policies define the rules and settings that users and devices must meet to be compliant, such as minimum operating systems, disk encryption, or Secure Boot. Device compliance policies can also include actions that apply to devices that are noncompliant, such as alerting users, blocking access, or wiping data. Device compliance policies can be integrated with Conditional Access, which can enforce attribute-driven policies based on the compliance status of the device. Attribute-driven policies are policies that use attributes of the device, user, or resource to determine the level of access or protection. For example, a policy can allow access to a resource only if the device is compliant, the user is in a certain group, and the resource is in a certain location. Attribute-driven policies provide more granular and flexible control over access and security than traditional policies based on roles or permissions. Therefore, the benefit of performing device compliance is providing attribute-driven policies, which is option D. References:

 Cisco Firepower is a unified security solution that combines firewall, intrusion prevention system (IPS), advanced malware protection (AMP), and threat intelligence features. Cisco ASA is a traditional firewall that focuses on network traffic control based on packet filtering and stateful inspection. One of the key differences between Cisco Firepower and Cisco ASA is that Cisco Firepower natively provides intrusion prevention capabilities while Cisco ASA does not. Intrusion prevention is the process of detecting and blocking malicious network traffic before it reaches the intended target. Cisco Firepower uses a combination of signature-based and behavior-based detection methods to identify and stop known and unknown attacks. Cisco ASA, on the other hand, does not have built-in intrusion prevention capabilities. It can only perform basic packet inspection and filtering based on predefined rules. To enable intrusion prevention on Cisco ASA, an additional module called FirePOWER Services is required. This module integrates Cisco Firepower features into Cisco ASA, but it is not the same as Cisco Firepower itself. Cisco Firepower offers more advanced and integrated security features than Cisco ASA with FirePOWER Services123. References: 1: Cisco ASA vs Cisco Firepower | What are the differences? - StackShare 2: Cisco FTD vs ASA: Difference and Comparison 3: CISCO FIREPOWER VS.

ExplanationExplanationCustomers must manage applications and data in PaaS.

DNS tunneling is a technique that exploits the DNS protocol to tunnel malware and other data through a client-server model. DNS tunneling can be used for data exfiltration, command and control, or IP-over-DNS tunneling. DNS tunneling works by encoding the information of other protocols or programs in DNS queries and responses. An attacker registers a domain, such as badsite.com, and sets up a malicious DNS server that can interpret the encoded data. The attacker then infects a client with malware that can send and receive DNS queries to the attacker’s domain. The malware can use DNS queries to request commands from the attacker, or to send sensitive data to the attacker. The DNS queries and responses look like normal DNS traffic, but they contain hidden data that can bypass network defenses123. References := 1: What Is DNS Tunneling? - Palo Alto Networks 2: What is DNS Tunneling? - Check Point Software 3: What Is DNS Tunneling and How to Detect and Prevent Attacks

ExplanationUmbrella Roaming is a cloud-delivered security service for Cisco’s next-generation firewall. It protects your employees even when they are off the VPN.

ExplanationExplanationCryptographic algorithms defined for use with IPsec include:+ HMAC-SHA1/SHA2 for integrity protection and authenticity.+ TripleDES-CBC for confidentiality+ AES-CBC and AES-CTR for confidentiality.+ AES-GCM and ChaCha20-Poly1305 providing confidentiality and authentication together efficiently.

ExplanationExplanationTo configure an NTP enabled router to require authentication when other devices connect to it, use thefollowing commands:NTP_Server(config)#ntp authentication-key 2 md5 securitytutNTP_Server(config)#ntp authenticateNTP_Server(config)#ntp trusted-key 2Then you must configure the same authentication-key on the client router:NTP_Client(config)#ntp authentication-key 2 md5 securitytutNTP_Client(config)#ntp authenticateNTP_Client(config)#ntp trusted-key 2NTP_Client(config)#ntp server 10.10.10.1 key 2Note: To configure a Cisco device as a NTP client, use the command ntp server . For example:Router(config)#ntp server 10.10.10.1. This command will instruct the router to query 10.10.10.1 for the time.
