350-701 Exam Dumps - Implementing and Operating Cisco Security Core Technologies (SCOR 350-701)

Explanation

The Firepower System uses network discovery and identity policies to collect host, application, and user data

for traffic on your network. You can use certain types of discovery and identity data to build a comprehensive

map of your network assets, perform forensic analysis, behavioral profiling, access control, and mitigate and

respond to the vulnerabilities and exploits to which your organization is susceptible.

You can configure your network discovery policy to perform host and application detection.

VMware APIC is a platform that integrates with Cisco ACI to provide enhanced visibility, policy integration and deployment, and security policies with access lists. VMware APIC is a virtual appliance that runs on VMware vSphere and communicates with the Cisco APIC controller. VMware APIC allows administrators to create and manage Cisco ACI policies for VMware virtual machines and networks. VMware APIC also provides a unified view of the physical and virtual network topology, health, and statistics. VMware APIC supports the following modes of Cisco ACI and VMware integration:

VMware VDS: When integrated with Cisco ACI, the VMware vSphere Distributed Switch (VDS) enables administrators to configure VM networking in the ACI fabric.

Cisco ACI Virtual Edge: Cisco ACI Virtual Edge is a distributed service that provides Layer 4 to Layer 7 services for applications running on VMware vSphere.

Cisco Application Virtual Switch (AVS): Cisco AVS is a distributed virtual switch that provides policy-based network services for VMware vSphere environments. References:

The Cisco DNA Center RESTful PNP API allows external applications to interact with the Plug and Play (PNP) service of Cisco DNA Center, which automates the onboarding and provisioning of network devices. The PNP API has several endpoints for different operations, such as importing, claiming, updating, and deleting devices. The endpoint that adds and claims a device into a workflow is api/v1/onboarding/pnp-device/import, which takes a JSON payload with the device information and the workflow ID. This endpoint creates a new device entry in the PNP database and associates it with the specified workflow. The workflow defines the configuration template, image, and license to be applied to the device during the provisioning process12. References:

Explanation

The command “snmp-server user user-name group-name [remote ip-address [udp-port port]] {v1 | v2c | v3 [encrypted] [auth {md5 | sha} auth-password]} [access access-list]” adds a new user (in this case “andy”) to an SNMPv3 group (in this case group name “myv3”) and configures a password for the user.

In the “snmp-server host” command, we need to:

+ Specify the SNMP version with key word “version {1 | 2 | 3}”

+ Specify the username (“andy”), not group name (“myv3”).

Note: In “snmp-server host inside …” command, “inside” is the interface name of the ASA interface through which the NMS (located at 10.255.254.1) can be reached.

Explanation

Domain name system (DNS) is the protocol that translates human-friendly URLs, such as securitytut.com, into IP addresses, such as 183.33.24.13. Because DNS messages are only used as the beginning of each communication and they are not intended for data transfer, many organizations do not monitor their DNS traffic for malicious activity. As a result, DNS-based attacks can be effective if launched against their networks. DNS tunneling is one such attack.

An example of DNS Tunneling is shown below:

The attacker incorporates one of many open-source DNS tunneling kits into an authoritative DNSnameserver (NS) and malicious payload.2. An IP address (e.g. 1.2.3.4) is allocated from the attacker’s infrastructure and a domain name (e.g. attackerdomain.com) is registered or reused. The registrar informs the top-level domain (.com) nameservers to refer requests for attackerdomain.com to ns.attackerdomain.com, which has a DNS record mapped to 1.2.3.43. The attacker compromises a system with the malicious payload. Once the desired data is obtained, the payload encodes the data as a series of 32 characters (0-9, A-Z) broken into short strings (3KJ242AIE9, P028X977W,…).4. The payload initiates thousands of unique DNS record requests to the attacker’s domain with each string as

Cisco Tetration is a hybrid-cloud workload protection platform that secures compute instances in both the on-premises data center and the public cloud1. One of the benefits of using Cisco Tetration is that it collects telemetry data from servers and then uses software sensors to analyze flow information2. This allows Cisco Tetration to provide comprehensive visibility into every workload interaction and powerful AI/ML driven automation2. By analyzing the flow information, Cisco Tetration can also generate microsegmentation policies, detect workload behavior anomalies, identify software vulnerabilities, and monitor policy compliance23. References: 1: Cisco Secure Workload (formerly Tetration) FAQ 2: Cisco Secure Workload Platform Data Sheet 3: Cisco Tetration Platform - Cisco

Explanation

DNS Tunneling is a method of cyber attack that encodes the data of other programs or protocols in DNS

queries and responses. DNS tunneling often includes data payloads that can be added to an attacked DNS

server and used to control a remote server and applications.

Using a company-managed Amazon S3 bucket for Cisco Umbrella logs allows the administrator to have full control over the access and lifecycle of the log data. This configuration can grant third-party SIEM integrations write access to the S3 bucket, which can enable more advanced analysis and correlation of the log data with other sources. This configuration also provides more flexibility in terms of how long the data can be stored offline, as opposed to the Cisco-managed S3 bucket, which has a fixed retention period of 30 days. References:
