The aaa server radius dynamic-author command enables authentication, authorization, and accounting (AAA) globally on the device so that Change of Authorization (CoA) is supported. CoA is a feature that allows an external AAA server to dynamically change the attributes of a user session after it is authenticated. For example, the AAA server can send a CoA request to reauthenticate a user, terminate a session, or apply a new policy. The aaa server radius dynamic-author command specifies the IP address and port number of the device that listens for CoA requests from the AAA server. The command also configures the shared secret key that is used to encrypt the communication between the device and the AAA server12. References := 1: Implementing and Operating Cisco Security Core Technologies (SCOR) v1.0, Module 3: Securing Networks with Cisco Firepower Next Generation Firewall, Lesson 3.2: Deploying Cisco Firepower Next-Generation Firewall, Topic 3.2.2: Cisco Firepower NGFW Device Management 2: Authentication, Authorization, and Accounting Configuration Guide, Cisco IOS Release 15SY - RADIUS Change of Authorization [Support] - Cisco3

Cisco Umbrella allows you to create custom destination lists that contain specific domains or IP addresses that you want to allow or block. You can then apply these destination lists to your policies to override the default behavior of Umbrella. For example, if you want to block specific addresses using Cisco Umbrella, you can create a destination list with those addresses and set the action to block. Then, you can assign this destination list to the policy that you want to modify. This way, any request to those addresses will be blocked by Umbrella, regardless of the content category or application settings12 References := 1: Manage Policies - Umbrella User Guide 2: Understanding Destination lists supported entries and error messages - Cisco Umbrella

The Secure Event Connector is a component of the Security Analytics and Logging (SaaS) solution that enables the FMC to send logs to the cloud-based service. The Secure Event Connector uses syslog to forward events from the FMC and the managed devices to the cloud. This method reduces the load on the firewall resources, as the events are sent in batches and compressed before transmission. The Secure Event Connector also provides encryption, authentication, and reliability for the log data. The other methods are not supported by the Security Analytics and Logging (SaaS) solution12 References := 1: Cisco Security Analytics and Logging (On Premises)

 Cisco AMP for Endpoints provides next-generation protection by leveraging an endpoint protection platform (EPP) and endpoint detection and response (EDR) capabilities. EPP is a set of multifaceted prevention techniques that stop threats from compromising endpoints, such as behavioral analytics, machine learning, and signature-based methods. EDR is a set of powerful features that reduce the attack surface and remediate faster, such as advanced threat hunting, endpoint isolation, and dynamic malware analysis. Cisco AMP for Endpoints also integrates with SecureX, a built-in platform that offers extended detection and response (XDR) capabilities across multiple control points, such as network, cloud, email, and web. By combining EPP, EDR, and XDR, Cisco AMP for Endpoints delivers a comprehensive and resilient endpoint security solution that can detect, respond, and recover from sophisticated attacks. References:

 Cisco Identity Services Engine (ISE) and AnyConnect Posture module are the best solution to ensure that all endpoints are compliant before users are allowed access on the corporate network. ISE is a policy-based platform that provides secure network access, identity management, and endpoint compliance. AnyConnect Posture module is a component of the AnyConnect Secure Mobility Client that performs posture assessment and remediation on the endpoints. Together, they can enforce policies based on the endpoint’s compliance status, such as the presence and update of the corporate antivirus application and the Windows 10 build version. The administrator can configure posture requirements, profiles, and policies on ISE, and deploy them to the endpoints through AnyConnect. The endpoints will then report their posture status to ISE, which will grant or deny network access accordingly, or redirect them to a remediation portal if needed. References :

Web requests are checked against policies beginning at the top of the table and ending at the first policy matched. Any policies below that point in the table are not processed. If no user-defined policy is matched against a Web request, then the global policy for that policy type is applied. Global policies are always positioned last in Policy tables and cannot be re-ordered.

Sandboxing is a feature that is leveraged by advanced antimalware capabilities to be an effective endpoint protection platform. Sandboxing allows an endpoint protection platform to isolate suspect files in a safe environment and analyze their behavior and impact without affecting the rest of the system. Sandboxing can help detect and prevent unknown or zero-day malware that may evade traditional signature-based detection methods. Sandboxing can also provide valuable threat intelligence and forensic data for further investigation and response.

Big data, storm centers, and blocklisting are not features that are leveraged by advanced antimalware capabilities to be an effective endpoint protection platform. Big data refers to the large volume, variety, and velocity of data that can be used for various purposes, such as analytics, machine learning, or business intelligence. Storm centers are centralized hubs that monitor and respond to cyber incidents and threats. Blocklisting is a method of preventing access to malicious or unwanted domains, IP addresses, or files by adding them to a list of blocked entities. References:

 The error 403: Forbidden indicates that the web server denied access to the requested resource, which in this case is the PCAP file. One possible reason for this error is that the HTTPS server is not enabled for the device platform policy, which is a configuration that applies to the FTD devices managed by the FMC. The device platform policy defines the settings for the management interface, the SSH access, the SNMP, the NTP, the DNS, and the HTTPS server. The HTTPS server allows the FMC to access the FTD devices via HTTPS and perform tasks such as packet capture, packet tracer, and file transfer. If the HTTPS server is not enabled for the device platform policy, the FMC cannot access the PCAP file from the FTD device via HTTPS. Therefore, the engineer must enable the HTTPS server for the device platform policy in order to resolve this issue. To enable the HTTPS server for the device platform policy, the engineer must follow these steps:

Log in to the FMC web interface and navigate to Devices > Platform Settings.

Select the device platform policy that applies to the FTD device and click Edit.

In the General tab, check the Enable HTTPS Server checkbox and click Save.

Deploy the policy changes to the FTD device and wait for the deployment to complete.

Try to access the PCAP file again from the FMC web browser using the same address.

Alternatively, the engineer can also enable the HTTPS server for the FTD device from the FTD CLI using the command configure network https-server enable. However, this method is not recommended because it may cause a configuration conflict with the FMC123

Explanation

DevSecOps (development, security, and operations) is a concept used in recent years to describe how to move

security activities to the start of the development life cycle and have built-in security practices in the continuous

integration/continuous deployment (CI/CD) pipeline. Thus minimizing vulnerabilities and bringing security closer

to IT and business objectives.

Three key things make a real DevSecOps environment:

+ Security testing is done by the development team.

+ Issues found during that testing is managed by the development team.

+ Fixing those issues stays within the development team.

 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”.

In XSS, an attacker will try to inject his malicious code (usually malicious links) into a database. When other users follow his links, their web browsers are redirected to websites where attackers can steal data from them. In a SQL Injection, an attacker will try to inject SQL code (via his browser) into forms, cookies, or HTTP headers that do not use data sanitizing or validation methods of GET/POST parameters.

A serverless application is one that does not require the developer to manage the underlying infrastructure or servers. Instead, the application code is executed by a cloud provider in response to events or triggers, such as HTTP requests, database changes, or messages. The cloud provider automatically provisions, scales, and manages the resources needed to run the code, and charges only for the time and resources consumed by the execution. A serverless application runs from an ephemeral, event-triggered, and stateless container that is fully managed by a cloud provider. This means that the container is created on demand when an event occurs, and is destroyed when the execution is completed. The container does not store any persistent state or data, and is isolated from other containers. The cloud provider handles the load balancing, fault tolerance, security, and monitoring of the container. A serverless application can leverage various cloud services, such as databases, storage, messaging, analytics, and machine learning, to perform complex tasks and functionalities. Serverless computing is a cloud-native development model that enables developers to focus on the business logic and deliver faster and more scalable applications. References:
