 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 :

CoA (Change of Authorization) is a feature that allows ISE to dynamically change the authorization attributes of an endpoint after it has been authenticated. CoA can be triggered by various events, such as posture assessment, profiling, or manual intervention1. There are different types of CoA that ISE can send to the network access device (NAD) to perform different actions on the endpoint session. The CoA type that achieves the goal of forcing an endpoint to re-authenticate without disrupting its session is CoA Reauth. CoA Reauth instructs the NAD to initiate a new RADIUS authentication for the endpoint, which allows ISE to apply a new or updated policy based on the latest attributes of the endpoint2. The other CoA types do not achieve this goal, as they either disconnect the endpoint session or do not change the authorization attributes. Port Bounce causes the NAD to shut down and bring up the port where the endpoint is connected, which effectively disconnects and reconnects the endpoint session2. CoA Terminate causes the NAD to terminate the endpoint session and send an Accounting-Stop message to ISE2. CoA Session Query causes the NAD to send an Accounting-Request message to ISE with the current session information, but does not change the authorization attributes of the endpoint2. References:

Cisco Umbrella and Cisco Duo Security are two solutions that help combat social engineering and phishing at the endpoint level. Cisco Umbrella is a cloud-based security platform that provides DNS-layer security, web filtering, and threat intelligence to protect users from malicious websites and domains. Cisco Duo Security is a multi-factor authentication (MFA) solution that verifies the identity of users and the health of their devices before granting access to applications. Both solutions help prevent attackers from compromising endpoints and stealing credentials or data through phishing or other social engineering techniques. References:

The threat intelligence standard that contains malware hashes is trusted automated exchange of indicator information (TAXII). TAXII is a protocol that enables the exchange of cyber threat information in a standardized and automated manner. It supports various types of threat intelligence, such as indicators of compromise (IOCs), observables, incidents, tactics, techniques, and procedures (TTPs), and campaigns. Malware hashes are one example of IOCs that can be shared using TAXII. Malware hashes are cryptographic signatures that uniquely identify malicious files or programs. They can be used to detect and block malware infections on endpoints or networks. TAXII uses STIX (structured threat information expression) as the data format for representing threat intelligence. STIX is a language that defines a common vocabulary and structure for describing cyber threat information. STIX allows threat intelligence producers and consumers to share information in a consistent and interoperable way. STIX defines various objects and properties that can be used to represent different aspects of cyber threat information, such as indicators, observables, incidents, TTPs, campaigns, threat actors, courses of action, and relationships. Malware hashes can be expressed as observables in STIX, which are concrete items or events that are observable in the operational domain. Observables can have various types, such as file, process, registry key, URL, IP address, domain name, etc. Each observable type has a set of attributes that describe its properties. For example, a file observable can have attributes such as name, size, type, hashes, magic number, etc. A hash attribute can have a type (such as MD5, SHA1, SHA256, etc.) and a value (such as the hexadecimal representation of the hash). A file observable can have one or more hash attributes to represent different hashing algorithms applied to the same file. For example, a file observable can have both MD5 and SHA256 hashes to increase the confidence and accuracy of identifying the file.

The other options are incorrect because they are not threat intelligence standards that contain malware hashes. Option A is incorrect because advanced persistent threat (APT) is not a standard, but a term that describes a stealthy and sophisticated cyberattack that aims to compromise and maintain access to a target network or system over a long period of time. Option B is incorrect because open command and control (OpenC2) is not a standard that contains malware hashes, but a language that enables the command and control of cyber defense components, such as sensors, actuators, and orchestrators. Option C is incorrect because structured threat information expression (STIX) is not a standard that contains malware hashes, but a data format that represents threat intelligence. STIX uses TAXII as the transport protocol for exchanging threat intelligence, including malware hashes. References:
