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:

Explanation

The command “crypto isakmp identity address 172.19.20.24” is not valid. We can only use “crypto isakmp

identity {address | hostname}. The following example uses preshared keys at two peers and sets both their

ISAKMP identities to the IP address.

At the local peer (at 10.0.0.1) the ISAKMP identity is set and the preshared key is specified:

crypto isakmp identity address

crypto isakmp key sharedkeystring address 192.168.1.33

At the remote peer (at 192.168.1.33) the ISAKMP identity is set and the same preshared key is specified:

crypto isakmp identity address

crypto isakmp key sharedkeystring address 10.0.0.1

One of the benefits of a Cisco Secure Email Gateway Virtual appliance compared to a physical one is the ability to allocate additional resources as needed. Virtual appliances can be easily scaled up by allocating more CPU, memory, or storage resources, providing flexibility and scalability in response to changing demands or growth.

Dynamic File Analysis submits eligible suspicious or unknown files to a sandbox, where the sample is executed in an instrumented environment. The sandbox observes runtime behavior such as process creation, file and registry changes, persistence activity, and outbound communications, then returns a disposition and detailed behavioral report. This capability is designed to expose malware that static signatures or reputation checks cannot confidently classify. Orbital Advanced Search performs endpoint hunting with flexible queries; it does not execute samples in a cloud sandbox. A Layer 4 traffic monitor examines transport-layer communication rather than file behavior. Application Visibility and Control identifies and controls network applications but is not an endpoint malware-analysis sandbox. Therefore, Dynamic File Analysis directly satisfies the requirement to execute suspicious files safely and determine their behavior. Cisco Threat Grid sandbox guidance

Storm control prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on one of the physical interfaces. A LAN storm occurs when packets flood the LAN, creating excessive traffic and degrading network performance. Errors in the protocol-stack implementation, mistakes in network configurations, or users issuing a denial-of-service attack can cause a storm.

By using the “storm-control broadcast level [falling-threshold]” we can limit the broadcast traffic on the switch.

 Cisco Web Security Appliance (WSA) is the platform that automatically blocks risky sites, and tests unknown sites for hidden advanced threats before allowing users to click them, using Cisco Cognitive Threat Analytics. Cisco Cognitive Threat Analytics is a cloud-based solution that reduces the time to discovery of threats operating inside the network by analyzing web traffic and detecting anomalous behavior. Cisco WSA integrates with Cisco Cognitive Threat Analytics to provide enhanced web security and breach detection. Cisco WSA can also leverage other Cisco security solutions, such as Cisco Umbrella, Cisco Advanced Malware Protection (AMP), and Cisco Talos Intelligence Group, to provide comprehensive web security. References:

Explanation

Two-factor authentication adds a second layer of security to your online accounts. Verifying your identity using a

second factor (like your phone or other mobile device) prevents anyone but you from logging in, even if they

know your password.

Note: Single sign-on (SSO) is a property of identity and access management that enables users to securely

authenticate with multiple applications and websites by logging in only once with just one set of credentials

(username and password). With SSO, the application or website that the user is trying to access relies on a

trusted third party to verify that users are who they say they are.

 Cisco Advanced Phishing Protection (AAP) is a solution that adds sophisticated machine learning capabilities to Cisco Email Security to block advanced identity deception attacks for inbound email by assessing its threat posture1. It also uses both global and local telemetry data combined with analytics and modeling to validate the reputation and authenticity of senders2. AAP provides sender authentication and BEC detection capabilities, and uses advanced machine learning techniques, real-time behavior analytics, relationship modeling and telemetry to protect against identity deception–based threats3.

In two ways, the Cisco Advanced Phishing Protection solution protects users:

It prevents use of compromised accounts and social engineering. AAP detects and blocks phishing emails that attempt to impersonate legitimate senders, such as executives, partners, or customers, and trick users into revealing sensitive information or transferring funds. AAP analyzes the sender’s identity, behavior, and relationship with the recipient, and assigns a risk score to the email. If the email is deemed suspicious or malicious, AAP can quarantine it, flag it, or deliver it with a warning4.

It automatically removes malicious emails from users’ inbox. AAP provides retrospective analysis and remediation capabilities, which means that it can identify and remove emails that were initially delivered but later found to be malicious. AAP leverages the Cisco Talos threat intelligence network and the Sensor-based solution to continuously monitor the threat landscape and update the email disposition accordingly. If an email is reclassified as malicious, AAP can automatically delete it from the users’ inbox, or notify the administrator or the user to take action45.

The other options are incorrect because they do not accurately describe the functions of AAP. AAP does not prevent all zero-day attacks coming from the Internet, as it focuses on phishing and identity deception attacks. AAP does not prevent trojan horse malware using sensors, as sensors are used to collect and analyze email data, not to block malware. AAP does not secure all passwords that are shared in video conferences, as it is not related to video conferencing security. Therefore, the correct answer is A and C. References:

Cisco ESA uses a multilayer approach to fight viruses and malware. The first layer of defense consists of outbreak filters, which the appliance downloads from Cisco SenderBase. Outbreak filters use global threat intelligence and behavioral analysis to identify and block emerging threats before they reach the network. The second layer of defense consists of antivirus engines, which scan the message body and attachments for known viruses and malware. Cisco ESA supports multiple antivirus engines, such as Sophos, McAfee, and Cisco AMP. The Sophos engine is one of the default engines that Cisco ESA uses, along with McAfee. The Sophos engine provides fast and accurate detection of viruses and malware, and updates its signatures frequently. The other options are not features that are used to configure Cisco ESA with a multilayer approach to fight viruses and malware. A white list is a list of trusted senders or recipients that are exempt from spam or virus filtering. RAT is the Recipient Access Table, which is used to determine whether the appliance accepts or rejects messages to a recipient address. DLP is Data Loss Prevention, which is used to prevent sensitive or confidential data from leaving the network. References :=

A DoS (Denial of Service) attack is a type of cyberattack that aims to disrupt the normal functioning of a server, service, or network by overwhelming it with a large amount of traffic or requests. A DoS attack typically uses a single computer or device to launch the attack, sending TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) packets to the target server. TCP and UDP are two common protocols used to send data over the internet. TCP packets require a connection to be established between the sender and the receiver, and ensure that the data is delivered reliably and in order. UDP packets do not require a connection, and do not guarantee the delivery or order of the data. Both TCP and UDP packets can be used to flood a server with requests, consuming its resources and bandwidth, and preventing legitimate users from accessing the service.

A DDoS (Distributed Denial of Service) attack is a type of DoS attack that uses multiple computers or devices to launch the attack, creating a large network of attackers that can generate more traffic or requests than a single source. A DDoS attack often involves a botnet, which is a network of compromised computers or devices that are controlled by a malicious actor, usually through malware or hacking. The botnet can send TCP or UDP packets to the target server from different locations and IP addresses, making it harder to trace and block the attack. A DDoS attack can also target multiple servers or services that are distributed over a LAN (Local Area Network), such as a web hosting service or a cloud computing platform, affecting the availability and performance of the entire network.

The main difference between a DoS attack and a DDoS attack is the number and diversity of the sources that are involved in the attack. A DoS attack comes from a single source, while a DDoS attack comes from multiple sources. This makes a DDoS attack more powerful, faster, and harder to stop than a DoS attack.

Explanation

Prevalence allows you to view files that have been executed in your deployment.

Note: Threat Root Cause shows how malware is getting onto your computers.

Simple Custom Detection is a feature of Cisco AMP for Endpoints that allows administrators to block specific files based on their SHA-256 or MD5 hashes. This feature can be used to detect and quarantine files of unknown disposition, such as abc424400664.zip, by adding their hashes to a custom list in the AMP portal. The list can then be applied to a policy that is assigned to the endpoints. Simple Custom Detection works on files of any type, size, or platform, unlike the other options that are either platform-specific (Android Custom Detection), size-limited (Blocked Application), or signature-based (Advanced Custom Detection). References: 1, 2, 3

A teardrop attack is a type of DoS attack that uses fragmented packets in an attempt to crash a target machine. The attacker sends IP packets that are deliberately malformed, such that the fragments overlap or have invalid offsets. When the target machine tries to reassemble the packets, it encounters an error or a buffer overflow, resulting in a system crash or a denial of service. Teardrop attacks exploit a vulnerability in the TCP/IP fragmentation reassembly process, which is responsible for splitting and recombining large packets that exceed the maximum transmission unit (MTU) size. Teardrop attacks can affect various operating systems, such as Windows, Linux, and BSD, depending on the implementation of the TCP/IP stack. Teardrop attacks are also known as IP fragmentation attacks or overlapping fragment attacks. References:
