The Talos IP and Domain Reputation Center is the world’s most comprehensive real-time threat detection network. It collects and analyzes data from millions of web requests, emails, malware samples, open-source data sets, endpoint intelligence, and network intrusions. It assigns a reputation score to IP addresses and domains based on their observed malicious activity and behavior. The reputation score can range from -10 (very malicious) to +10 (very benign). The reputation score can be used to block or allow traffic, or to trigger further inspection or analysis. The Talos IP and Domain Reputation Center allows you to track the reputation of IP addresses for email and web traffic, as well as to look up the category, volume, and history of any IP address or domain. You can also submit feedback or request a change of reputation for any IP address or domain. References 

vulnerability is a flaw or gap in the security of a system or network that can be exploited by an attacker to compromise its functionality, integrity, confidentiality, or availability. A vulnerability can exist in the design, implementation, configuration, or operation of a system or network, and can be caused by human errors, software bugs, hardware defects, or environmental factors. A vulnerability can be exploited by an attacker using various methods, such as malware, phishing, brute force, denial-of-service, or injection attacks. A vulnerability can also be exploited by an insider who has legitimate access to the system or network, but abuses their privileges for malicious purposes. A vulnerability can be discovered by security researchers, ethical hackers, or malicious hackers, and can be reported to the vendor or the public for remediation or exploitation. A vulnerability can be mitigated by applying patches, updates, or configuration changes, or by using security tools such as firewalls, antivirus, or encryption.

An exploit is a piece of code, data, or technique that takes advantage of a vulnerability to perform unauthorized or malicious actions on a system or network. An exploit can be used to gain access, escalate privileges, execute commands, steal data, disrupt services, or damage resources. An exploit can be delivered by various means, such as email attachments, web links, removable media, or network packets. An exploit can be developed by security researchers, ethical hackers, or malicious hackers, and can be shared or sold on the dark web or other platforms for testing or attacking purposes. An exploit can be detected by security tools such as intrusion detection systems, antivirus, or anti-exploit software.

The difference between a vulnerability and an exploit is that a vulnerability is a potential weakness that can be exploited, while an exploit is an actual attack that uses a vulnerability. A vulnerability can exist without being exploited, but an exploit cannot exist without a vulnerability. A vulnerability can be fixed or prevented, but an exploit can only be blocked or stopped. References :=

Explanation

You can configure discovery rules to tailor the discovery of host and application data to your needs.

The Firepower System can use data from NetFlow exporters to generate connection and discovery events, and to add host and application data to the network map.

A network analysis policy governs how traffic is decoded and preprocessed so it can be further evaluated, especially for anomalous traffic that might signal an intrusion attempt -> Answer D is not correct.
