To implement external authentication against Active Directory, the Cisco ISE server needs to communicate with the domain controller using either RADIUS or LDAP protocols. RADIUS is used for network access control, while LDAP is used for identity management and directory services. Both protocols require the appropriate ports to be opened and firewall rules to be configured to allow the traffic between the ISE server and the domain controller.

The ISE account does not need to be a domain administrator in Active Directory to perform JOIN operations. It only needs to have the permissions to create computer objects and reset passwords in the domain. This can be achieved by delegating the rights to a specific OU or using a service account with limited privileges.

Active Directory supports user and machine authentication by using various methods, not only MSCHAPv2. MSCHAPv2 is a challenge-response authentication protocol that is commonly used with RADIUS and VPN connections. However, Active Directory also supports other protocols such as Kerberos, NTLM, EAP, and PEAP, depending on the scenario and the client capabilities.

Spero analysis is a feature of Cisco AMP for Networks that examines structural characteristics such as metadata and header information in executable files. After generating a Spero signature based on this information, if the file is an eligible executable file, the device submits it to the Spero heuristic engine in the AMP cloud for analysis1. Spero analysis can detect malware based on the file’s structure and behavior, without requiring a full file upload2. Spero analysis is different from dynamic analysis, sandbox analysis, and malware analysis, which are other features of Cisco AMP for Networks that perform different types of file inspection and analysis3. References: 1: How to configure Firepower AMP to not upload files to … - Cisco Community 2: File Policies - Network Direction 3: Cisco AMP for Networks - Cisco

Explanation

Cisco Cognitive Threat Analytics helps you quickly detect and respond to sophisticated, clandestine attacks that are already under way or are attempting to establish a presence within your environment. The solution automatically identifies and investigates suspicious or malicious web-based traffic. It identifies both potential and confirmed threats, allowing you to quickly remediate the infection and reduce the scope and damage of an attack, whether it’s a known threat campaign that has spread across multiple organizations or a unique threat you’ve never seen before.

Detection and analytics features provided in Cognitive Threat Analytics are shown below:

+ Data exfiltration: Cognitive Threat Analytics uses statistical modeling of an organization’s network to identify anomalous web traffic and pinpoint the exfiltration of sensitive data. It recognizes data exfiltration even in HTTPS-encoded traffic, without any need for you to decrypt transferred content

+ Command-and-control (C2) communication: Cognitive Threat Analytics combines a wide range of data, ranging from statistics collected on an Internet-wide level to host-specific local anomaly scores. Combining these indicators inside the statistical detection algorithms allows us to distinguish C2 communication from benign traffic and from other malicious activities. Cognitive Threat Analytics recognizes C2 even in HTTPSencoded or anonymous traffic, including Tor, without any need to decrypt transferred content, detecting a broad

range of threats

Active Directory (AD) is an ID store that requires that a shadow user be created on Cisco ISE for the admin login to work. A shadow user is a user account that is defined in the ISE internal database, but has the password set to external. This means that the user authentication is performed against an external identity source, such as AD, while the user authorization is based on the ISE admin group membership. A shadow user is useful when the admin wants to assign different roles or permissions to specific AD users, rather than using AD groups. To create a shadow user, the admin must check the External checkbox in the ISE admin user configuration, and make sure that the username matches the AD username. The shadow user must also be assigned to an ISE admin group that has the Type set to External123. References := 1: ISE Admin User Shadow AD Account Issue 2: ISE Admin user authentication from AD 3: Which ID store requires that a shadow user be created on Cisco ISE for the admin login to work?

Cisco Workload Optimization Manager provides specific real-time actions that ensure workloads get the

resources they need when they need them, enabling continuous placement, resizing, and capacity decisions that can be automated, driving continuous health in the environment. You can automate the software’s decisions according to your level of comfort: recommend (view only), manual (select and apply), or automated (executed in real time by software).

 Cisco Duo is a cloud-based solution that provides multi-factor authentication (MFA) and device trust for secure access to applications and data. MFA adds an extra layer of security by requiring users to verify their identity with something they know (such as a password) and something they have (such as a phone or a hardware token). Device trust ensures that only trusted devices can access sensitive resources by checking the device health and compliance. Cisco Duo can help prevent social engineering attacks by making it harder for hackers to impersonate legitimate users or compromise their credentials. Cisco Duo can also integrate with other Cisco security products, such as Cisco AnyConnect, Cisco AMP for Endpoints, and Cisco Umbrella, to provide a comprehensive security solution. References :=

Cisco Advanced Phishing Protection provides sender authentication and BEC detection capabilities. It uses advanced machine learning techniques, real-time behavior analytics, relationship modeling, and telemetry to protect against identity deception-based threats.

sfr {fail-open | fail-close [monitor-only]} < - There ' s a couple different options here. The first one is fail-open which means that if the Firepower software module is unavailable, the ASA will continue to forward traffic. fail-close means that if the Firepower module fails, the traffic will stop flowing. While this doesn ' t seem ideal, there might be a use case for it when securing highly regulated environments. The monitor-only switch can be used with both and basically puts the Firepower services into IDS-mode only. This might be useful for initial testing or setup.

PFS stands for Perfect Forward Secrecy, which is a property of some cryptographic protocols that ensures that the compromise of a long-term key does not affect the security of past or future sessions. PFS provides the highest level of protection against brute-force attacks, because even if an attacker manages to break the long-term key, they cannot decrypt the previous or subsequent communications that use different session keys. PFS is achieved by using ephemeral or temporary keys that are derived from a Diffie-Hellman key exchange, and are not based on the long-term key. Therefore, each session has a unique and independent key that is not stored or reused. PFS is supported by some protocols such as TLS, SSH, and IPsec123. References := 1: Implementing and Operating Cisco Security Core Technologies (SCOR) v1.0, Module 4: Securing Networks with Cisco Firepower Next Generation IPS, Lesson 4.1: Deploying Cisco Firepower Next-Generation IPS, Topic 4.1.2: Cisco Firepower NGIPS Device Management 2: What is Perfect Forward Secrecy? | Baeldung on Computer Science4 3: Perfect Forward Secrecy - an overview | ScienceDirect Topics5

Explanation

Cisco‘s Group Encrypted Transport VPN (GETVPN) introduces the concept of a trusted group to eliminate

point-to-point tunnels and their associated overlay routing. All group members (GMs) share a common security

association (SA), also known as a group SA. This enables GMs to decrypt traffic that was encrypted by any

other GM.

GETVPN provides instantaneous large-scale any-to-any IP connectivity using a group IPsec security paradigm.

IETF RADIUS attribute 31 is Calling-Station-ID, which commonly carries the endpoint MAC address. Consequently, A is the only option that matches the attribute number stated in the requirement. Cisco ISE can use this endpoint identifier to correlate authentication context and locate the appropriate active session when issuing a Change of Authorization disconnect or reauthorization; Cisco’s monitoring guide confirms that CoA requires a MAC address or session ID. The ISE Administrator Guide explicitly identifies Calling-Station-ID as attribute 31. Message-Authenticator protects packet integrity; it is not attribute 31. Acct-Session-ID has a different attribute number, while NAS-Port-ID identifies the access port. Thus, configuring Calling-Station-ID satisfies the stated identification requirement.

Software composition analysis inventories third-party and open-source packages, identifies their versions and dependencies, and compares them with vulnerability and licensing information. Running SCA during the build stage shifts dependency checking left, allowing a vulnerable component to fail policy before the application is released. Therefore, B directly addresses the risk in the question. The joint CISA and security-agency guidance on managing open-source software and software bills of materials explains that SCA tools analyze application dependencies for vulnerabilities and open-source license violations. Static and dynamic routing choices affect packet forwarding, while round-robin DNS affects service distribution. None of those networking mechanisms examines software libraries, transitive dependencies, known CVEs, or component licenses within a DevSecOps pipeline.

 To add switches into the fabric, administrators can use PowerOn Auto Provisioning (POAP) or Seed IP methods. POAP is a feature that automates the process of upgrading software images and installing configuration files on Cisco switches that are being deployed in the network for the first time. Seed IP is a method that allows administrators to specify the IP address of a switch that is already part of the fabric, and then use it to discover and add other switches that are connected to it. Both methods enable administrators to control how switches are added into DCNM for private cloud management. References:

POAP, section “PowerOn Auto Provisioning (POAP)”.

Seed IP, section “Add Switches”.

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:
