sfr {fail-open | fail-close [monitor-only]} <- There's a couple different options here. The first one is fail-open which means that if the Firepower software module is unavailable, the ASA will continue to forward traffic. fail-close means that if the Firepower module fails, the traffic will stop flowing. While this doesn't seem ideal, there might be a use case for it when securing highly regulated environments. The monitor-only switch can be used with both and basically puts the Firepower services into IDS-mode only. This might be useful for initial testing or setup.

 Multifactor authentication (MFA) is a solution that requires the user to provide two or more verification factors to gain access to a resource, such as an application, online account, or a VPN. MFA is more secure than the traditional use of a username and password because it reduces the risk of identity theft, phishing, and credential compromise. MFA can use different types of factors, such as something the user knows (e.g., password, PIN), something the user has (e.g., smartphone, token, smart card), or something the user is (e.g., fingerprint, facial recognition). MFA can be implemented using various methods, such as security defaults, Conditional Access policies, or third-party solutions123. References:

Explanation

Compared to RSA, the prevalent public-key cryptography of the Internet today, Elliptic Curve Cryptography (ECC) offers smaller key sizes, faster computation,as well as memory, energy and bandwidth savings and is thus better suited forsmall devices.

A traffic profile is a graph of network traffic based on connection data collected over a profiling time window (PTW). This measurement presumably represents normal network traffic. After the learning period, you can detect abnormal network traffic by evaluating new traffic against your profile. You can also set up inactive periods in traffic profile to exclude data that does not reflect normal network behavior. You can use traffic profiles to write correlation rules that trigger when the traffic deviates from the profile by a certain threshold or standard deviation. This way, you can identify and respond to potential attacks or security policy violations that cause traffic anomalies. References :=

Which statement describes a traffic profile on a Cisco Next Generation Intrusion Prevention System?

Transparent traffic redirection using WCCP is a deployment mode for the Cisco WSA that allows it to intercept and proxy web requests from client applications without requiring any configuration on the clients. This mode increases the visibility and control of web traffic, while making the proxy function invisible to the users. To support this mode, the Cisco WSA must be configured to use the transparent proxy mode, which enables it to listen on ports 80 and 443 for HTTP and HTTPS traffic, respectively. The Cisco WSA must also be configured to use WCCP service IDs, which are numerical identifiers that specify the type and range of ports to be redirected. For example, service ID 0 (web-cache) redirects port 80, service ID 70 (https-cache) redirects port 443, and service ID 60 (ftp-native) redirects port 21 and a range of passive FTP ports. The Cisco WSA must also be configured to join a WCCP group, which is a set of WCCP routers or switches that cooperate to redirect traffic to the WSA. The WCCP group can be specified by a group list, which is an access list that defines the IP addresses of the WCCP routers or switches, or by a password, which is a shared secret that authenticates the WCCP communication. The WCCP group must also be configured on the network device that performs the traffic redirection, such as a Cisco router, switch, or ASA firewall. The network device must support WCCPv2, which is the latest version of the protocol that allows for advanced features such as load balancing, encryption, and GRE encapsulation. The network device must also be configured to use the same WCCP service IDs and group list or password as the Cisco WSA. The network device must also be configured to apply the WCCP redirection to the appropriate interface and direction, such as the inside interface and inbound direction for traffic originating from the internal network. The network device must also be configured to use an access list that defines the traffic to be redirected or bypassed, such as the source and destination IP addresses, ports, and protocols. The access list can also be used to exclude certain traffic from WCCP redirection, such as traffic to private or internal destinations, or traffic from specific hosts123 References := 1: Configure Transparent Redirection With WCCP in Order to Redirect Native FTP Traffic - Cisco 2: Solved: Transparent Redirection - Cisco Community 3: Cisco WSA : Is it possible to use web proxy in transparent mode without WCCP - Cisco Community
