Threat intelligence is the term for having information about threats and threat actors that helps mitigate harmful events that would otherwise compromise networks or systems. Threat intelligence is the result of collecting, analyzing, and contextualizing data from various sources, such as network traffic, logs, feeds, reports, etc. Threat intelligence provides insights into the tactics, techniques, and procedures (TTPs) of adversaries, as well as their motivations, intentions, and capabilities. Threat intelligence can help organizations to detect, prevent, and respond to cyberattacks, as well as to improve their security posture and resilience12. The other options are not correct, because they are not terms for having information about threats and threat actors. Trusted automated exchange is a concept that refers to the sharing of threat intelligence among trusted entities in a timely and secure manner3. Indicators of Compromise (IoCs) are pieces of forensic data, such as IP addresses, domains, hashes, etc., that indicate a potential intrusion or compromise of a system or network. The Exploit Database is a public repository of exploits and vulnerable software, maintained by Offensive Security. References:

 Posture is a feature within Cisco ISE that verifies the compliance of an endpoint before providing access to the network. Posture assessment checks the state of the endpoint, such as the operating system, antivirus, firewall, patches, and so on, against the predefined policies. If the endpoint does not meet the policy requirements, it can be remediated by installing or updating the necessary software or configuration. Posture assessment can be done for both wired and wireless endpoints, as well as VPN clients. Posture assessment requires the installation of a posture agent on the endpoint, which communicates with the posture service on the ISE server. The posture agent can be either a persistent agent, which runs in the background and provides continuous assessment, or a temporal agent, which runs on-demand and is removed after the assessment is complete. Posture assessment can be integrated with 802.1X or web authentication methods for network access control. References :=

Explanation

In deceptive phishing, fraudsters impersonate a legitimate company in an attempt to steal people’s personal data or login credentials. Those emails frequently use threats and a sense of urgency to scare users into doing what the attackers want.

Spear phishing is carefully designed to get a single recipient to respond. Criminals select an individual target within an organization, using social media and other public information – and craft a fake email tailored for that person.

EPP and EDR are two types of endpoint security solutions that have different goals and capabilities. EPP stands for endpoint protection platform, which is a suite of technologies that work together to prevent, detect, and remediate security threats on endpoints. EPP solutions use techniques such as antivirus, firewall, application control, and patch management to block known and unknown malware and malicious activity. EDR stands for endpoint detection and response, which is a solution that provides real-time visibility into endpoint activities and enables security teams to detect, investigate, and respond to advanced threats that may have bypassed EPP defenses. EDR solutions use techniques such as behavioral analysis, threat intelligence, and incident response to flag offending files at the first sign of malicious behavior, contain and isolate compromised endpoints, and remediate the damage caused by the attack. Therefore, the correct answer is D, as having an EDR solution gives an engineer the capability to flag offending files at the first sign of malicious behavior. The other options are incorrect because:

A is false, as EPP focuses primarily on threats that have evaded front-line defenses that entered the environment, not EDR.

B is false, as having an EPP solution allows an engineer to detect, investigate, and remediate modern threats, not EDR.

C is false, as EDR focuses on detection and response at the endpoint level, not prevention at the perimeter. References:

Explanation

The appliance will try once to upload the file; if upload is not successful, for example because of

connectivity problems, the file may not be uploaded. If the failure was because the file analysis server was overloaded, the upload will be attempted once more.

Explanation

The ASAv on AWS supports the following features:

+ Support for Amazon EC2 C5 instances, the next generation of the Amazon EC2 Compute Optimized instance

family.

+ Deployment in the Virtual Private Cloud (VPC)

+ Enhanced networking (SR-IOV) where available

+ Deployment from Amazon Marketplace

+ Maximum of four vCPUs per instance

+ User deployment of L3 networks

+ Routed mode (default)

Note: The Cisco Adaptive Security Virtual Appliance (ASAv) runs the same software as physical Cisco ASAs to deliver proven security functionality in a virtual form factor. The ASAv can be deployed in the public AWS cloud.

It can then be configured to protect virtual and physical data center workloads that expand, contract, or shift their location over time. Reference: https://www.cisco.com/c/en/us/td/docs/security/asa/asa96/asav/quick-start-book/asav-96 qsg/asavaws.html

Explanation

SSL Decryption is an important part of the Umbrella Intelligent Proxy. he feature allows the Intelligent Proxy to go beyond simply inspecting normal URLs and actually proxy and inspect traffic that’s sent over HTTPS. The SSL Decryption feature does require the root certificate be installed.

IKEv1 has two modes of operation: main mode and aggressive mode. Main mode uses six messages to establish the IKE SA, while aggressive mode uses only three messages. Therefore, aggressive mode is faster than main mode, but less secure, as it exposes the identities of the peers in cleartext. This makes it vulnerable to man-in-the-middle attacks. IKEv2 does not have these modes, but uses a single four-message exchange to establish the IKE SA. IKEv2 also encrypts the identities of the peers, making it more secure than IKEv1 aggressive mode.

IKEv1 uses EAP authentication only for remote access VPNs, not for site-to-site VPNs. IKEv2 supports EAP authentication for both types of VPNs. EAP authentication allows the use of various authentication methods, such as certificates, tokens, or passwords.

IKEv1 conversations are initiated by the ISAKMP header, which contains the security parameters and the message type. IKEv2 conversations are initiated by the IKE_SA_INIT message, which contains the security parameters, the message type, and the message ID. The message ID is used to identify and order the messages in the IKEv2 exchange.

NAT-T is supported by both IKEv1 and IKEv2. NAT-T stands for Network Address Translation-Traversal, and it is a mechanism that allows IKE and IPsec traffic to pass through a NAT device. NAT-T detects the presence of NAT and encapsulates the IKE and IPsec packets in UDP headers, so that they can be translated by the NAT device. References:

The command show authen sess int gi0/1 displays the authentication session information for the interface gi0/1, such as the MAC address, the authentication method, the authentication state, the session timeout, and the VLAN assignment. This command is useful for verifying the status of an 802.1X connection on a specific interface. The other commands are not related to 802.1X authentication. The command show authorization status displays the authorization status for the current user. The command show connection status gi0/1 is not a valid Cisco command. The command show ver gi0/1 displays the version information for the interface gi0/1. References: 802.1X Authentication Commands, Configuring IEEE 802.1x Port-Based Authentication, What Cisco command shows you the status of an 802.1X connection on interface gi0/1?

To block a website based on a custom list, the customer should add the websites to a blocked type destination list. A destination list is a custom list of domains or URLs that the customer wants to allow or block for their identities. The customer can create destination lists through the Policy Components > Destination Lists page, or within the policy wizard when creating or editing a policy. The custom URL destination block lists feature enables Umbrella to extend a domain level block list to encompass full and partial URLs. In turn, this allows the customer to block certain portions of a website based specifically on the full or partial URL. This feature requires the customer to enable the intelligent proxy and install a root certificate for SSL decryption. References:
