 Intelligent Multi-Scan (IMS) is a feature that enables the Cisco ESA to perform multiple anti-spam scans on each message and apply different actions based on the results. IMS also includes the Graymail Detection and Safe Unsubscribe services, which allow the ESA to identify and filter messages that are not strictly spam, but are low-priority or unwanted by the end user, such as newsletters, social media notifications, or marketing emails. The Graymail Detection service can classify messages into different categories, such as bulk, mass, or subscription, and assign different scores and verdicts to them. The Safe Unsubscribe service can provide a link for the end user to safely unsubscribe from the sender’s mailing list, without revealing their email address or opening a malicious URL. To enable the blocking of greymail for the end user, the administrator must first enable the IMS feature globally and then configure the Graymail and Safe Unsubscribe settings in the mail policies. The administrator can also enable the centralized spam quarantine and the end-user quarantine interface to allow the end user to manage their own quarantined messages. References :=

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:

Traffic storm control is a feature that prevents LAN ports from being disrupted by a broadcast, multicast, or unicast traffic storm on physical interfaces. Traffic storm control monitors the level of each traffic type for which it is enabled in 1-second intervals and compares it with the configured threshold, which is a percentage of the total available bandwidth of the port. When the ingress traffic reaches the threshold, traffic storm control drops the traffic until the end of the interval. Traffic storm control uses the Individual/Group bit in the packet destination address to determine if the packet is unicast or broadcast. This bit is set to 0 for unicast addresses and 1 for multicast or broadcast addresses. Traffic storm control does not use the source address to classify the traffic type. References := Configuring Traffic Storm Control - Cisco, Understanding Cisco Traffic Storm Control - NetCraftsmen

The Cisco Stealthwatch system collects and analyzes network telemetry such as flow (NetFlow, sFlow, JFlow, IPFIX, etc.) from routers, switches, and firewalls to monitor network and user behavior. The system conducts sophisticated, proprietary analytics on network data to automatically detect abnormal behaviors that may signify an attack1. NetFlow is a protocol that provides information about network traffic flows, such as source and destination IP addresses, ports, protocols, bytes, packets, and timestamps. NetFlow data can be used to identify network anomalies, bandwidth usage, application performance, and security incidents2. References :=

The Python script in the exhibit uses the Cisco AMP for Endpoints API to get information about the computers in the deployment. It imports the requests library, which allows it to make HTTP requests. It then defines three variables: client_id, api_key, and url. These are used to authenticate and access the API endpoint. The url is set to ‘1’, which returns a list of computers in JSON format. The script then makes a GET request using the requests.get() method, passing the url and the authentication details as parameters. The response from the API is stored in the response variable, and converted to JSON using the response.json() method. The script then loops over each computer in the ‘data’ field of the JSON response, using a for loop. Inside the loop, it extracts the hostname of each computer using the ‘hostname’ key, and prints it using the print() function. Therefore, the script will pull all computer hostnames and print them, which is option C. References:

Cisco ISE uses probes to collect endpoint attributes that are used in profiling. Probes are software modules that run on the ISE Policy Service Nodes (PSNs) and gather information about the endpoints connected to the network. Probes can use various protocols and methods to collect endpoint attributes, such as RADIUS, DHCP, SNMP, HTTP, DNS, NetFlow, NMAP, Active Directory, and Cisco pxGrid. The collected attributes are then matched to predefined or custom conditions that define the endpoint profiles. Endpoint profiling enables ISE to identify and classify the endpoints and apply the appropriate policies based on their identity, role, and context12. References: 1: Cisco ISE 2.4 Endpoint Profiling - Cisco 2: How To Create an Endpoint Profile - Cisco Community

Explanation

The term ‘rootkit’ originally comes from the Unix world, where the word ‘root’ is used to describe a user with the

highest possible level of access privileges, similar to an ‘Administrator’ in Windows. The word ‘kit’ refers to the

software that grants root-level access to the machine. Put the two together and you get ‘rootkit’, a program that

gives someone – with legitimate or malicious intentions – privileged access to a computer.

There are four main types of rootkits: Kernel rootkits, User mode rootkits, Bootloader rootkits, Memory rootkits

Device compliance checks are a feature of Cisco Identity Services Engine (ISE) that allows you to verify the posture of endpoints before allowing them to access your network. Posture is the state of the endpoint in terms of security, such as the presence of anti-virus software, firewall, patches, and so on. A posture agent, such as the AnyConnect ISE Posture Agent, runs on the endpoint and collects posture information, which is then sent to the ISE server for evaluation. Based on the posture policy, the ISE server can grant or deny network access, or apply remediation actions to the endpoint. One of the benefits of conducting device compliance checks is that it validates if anti-virus software is installed on the endpoint, which can prevent malware infections and protect your network from threats. The other options are not benefits of device compliance checks, as they are not related to the posture of the endpoint. References:

 Cisco Duo is a multi-factor authentication (MFA) solution that verifies the identity of all users with Duo’s easy, one-tap-approval MFA app. It also provides device visibility and adaptive policies to ensure that only trusted devices can access corporate applications and networks. Some of the benefits of using Cisco Duo as an MFA solution are:

It provides a simple and streamlined login experience for multiple applications and users. Users can access all their applications from a single dashboard, and authenticate with a simple push notification or other convenient methods. Duo also supports single sign-on (SSO) for integrated applications, reducing the need for multiple passwords and logins12.

It offers native integration that helps secure applications across multiple cloud platforms or on-premises environments. Duo can be easily integrated with most major apps and custom applications, enabling a secure access solution that can be implemented with minimal IT involvement. Duo also supports various protocols and standards, such as SAML, RADIUS, LDAP, and WebAuthn, to enable seamless integration with different environments13.

Explanation

The Version 1 format was the initially released version. Do not use the Version 1 format unless you are using a legacy collection system that requires it. Use Version 9 or Version 5 export format.

Version 5 export format is suitable only for the main cache; it cannot be expanded to support new features.

Version 8 export format is available only for aggregation caches; it cannot be expanded to support new

features.

A cloud access security broker (CASB) is a security solution that helps protect cloud-hosted services and applications from cyberattacks and data breaches. A CASB acts as an intermediary between cloud users and cloud providers, and enforces the organization’s security policies and compliance requirements. A CASB integrates with other cloud solutions via APIs and monitors the cloud activity and data across multiple platforms and devices. A CASB can also create incidents based on events from the cloud solution, such as unauthorized access, data leakage, malware infection, or policy violation. A CASB can then alert the administrators, block the malicious actions, or remediate the issues. A CASB provides visibility, control, and protection for the organization’s cloud environment12.
