ExplanationThe ASA REST API gives you programmatic access to managing individual ASAs through a Representational State Transfer (REST) API. The API allows external clients to perform CRUD (Create, Read, Update, Delete) operations on ASA resources; it is based on the HTTPS protocol and REST methodology.All API requests are sent over HTTPS to the ASA, and a response is returned.Request StructureAvailable request methods are:GET – Retrieves data from the specified object.PUT – Adds the supplied information to the specified object; returns a 404 Resource Not Found error if the object does not exist.POST – Creates the object with the supplied information.DELETE – Deletes the specified object

Proxy caching is a method that enables a proxy server to save recent and frequent website/webpage requests and data requested by one or more client machines. It reduces latency, eases bandwidth consumption, and ensures content is served more swiftly to the end-user12. WSA (Web Security Appliance) is a Cisco product that provides proxy caching functionality, along with other web security features such as malware protection, URL filtering, and data loss prevention3. Firepower, FireSIGHT, and ASA are other Cisco products that do not provide proxy caching, but rather focus on different aspects of network security, such as threat detection, management, and firewall . References:

ExplanationExplanationWhen Umbrella receives a DNS request, it uses intelligence to determine if the request is safe, malicious or risky — meaning the domain contains both malicious and legitimate content. Safe and malicious requests are routed as usual or blocked, respectively. Risky requests are routed to our cloud-based proxy for deeper inspection. The Umbrella proxy uses Cisco Talos web reputation and other third-party feeds to determine if a URL is malicious.

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?

 Suppression is a feature of Cisco Next Generation Intrusion Prevention System (NGIPS) that allows you to reduce false positives and unwanted alerts by filtering out specific traffic from the intrusion detection and prevention process. You can configure suppression based on different criteria, such as port, rule, source, destination, and network. The two valid suppression types for this question are port and rule. Port suppression allows you to exclude traffic based on the source or destination port number, or both. For example, you can suppress alerts for port 80 (HTTP) traffic if you are not interested in web-based attacks. Rule suppression allows you to exclude traffic based on the rule ID (SID) or the rule category. For example, you can suppress alerts for rules that belong to the policy-violations category if you are not concerned about them. You can also suppress alerts for specific rules that are not relevant to your network or generate too many false positives. References

 Cisco Advanced Malware Protection (AMP) for Endpoints is a cloud-based solution that provides endpoint protection against malware and advanced threats. It can be deployed in different architectures depending on the customer’s needs and preferences. One of the deployment options is the private cloud, which is designed to keep data within a network perimeter. In this option, the customer hosts the AMP for Endpoints console and the AMP cloud on their own infrastructure, and the endpoints connect to the private cloud for analysis and policy enforcement. This option provides more control and privacy over the data, but also requires more resources and maintenance from the customer. The other deployment options are the public cloud, which uses the Cisco-hosted AMP cloud and console, and the hybrid cloud, which uses a combination of the public and private clouds123 References: 1: Protecting Against Malware Threats with Cisco AMP for Endpoints (SSFAMP) course overview 2: Cisco Secure Endpoint (Formerly AMP for Endpoints) - Cisco 3: Cisco Advanced Malware Protection for Endpoints - Zones

ExplanationThe AES encryption algorithm encrypts and decrypts data in blocks of 128 bits (block size). It can do this using 128-bit, 192-bit, or 256-bit keys

ExplanationCisco Cloudlock is a cloud-native cloud access security broker (CASB) that helps you move to the cloud safely. It protects your cloud users, data, and apps. Cisco Cloudlock provides visibility and compliance checks, protects data against misuse and exfiltration, and provides threat protections against malware like ransomware.

ExplanationDTLS is used for delay sensitive applications (voice and video) as its UDP based while TLS is TCP based.Therefore DTLS offers strongest throughput performance. The throughput of DTLS at the time of AnyConnect connection can be expected to have processing performance close to VPN throughput.

ExplanationThe term ‘rootkit’ originally comes from the Unix world, where the word ‘root’ is used to describe a user with thehighest possible level of access privileges, similar to an ‘Administrator’ in Windows. The word ‘kit’ refers to thesoftware that grants root-level access to the machine. Put the two together and you get ‘rootkit’, a program thatgives someone – with legitimate or malicious intentions – privileged access to a computer.There are four main types of rootkits: Kernel rootkits, User mode rootkits, Bootloader rootkits, Memory rootkits

ExplanationPing of Death (PoD) is a type of Denial of Service (DoS) attack in which an attacker attempts to crash,destabilize, or freeze the targeted computer or service by sending malformed or oversized packets using a simple ping command.A correctly-formed ping packet is typically 56 bytes in size, or 64 bytes when the ICMP header is considered,and 84 including Internet Protocol version 4 header. However, any IPv4 packet (including pings) may be as large as 65,535 bytes. Some computer systems were never designed to properly handle a ping packet larger than the maximum packet size because it violates the Internet Protocol documentedLike other large but well-formed packets, a ping of death is fragmented into groups of 8 octets beforetransmission. However, when the target computer reassembles the malformed packet, a buffer overflow can occur, causing a system crash and potentially allowing the injection of malicious code.

 Tetration is the solution that protects hybrid cloud deployment workloads with application visibility and segmentation. Tetration enables a zero-trust model using segmentation, which allows you to identify security incidents faster, contain lateral movement, and reduce your attack surface. Tetration supports both on-premises and public cloud workloads and provides real-time telemetry data, behavior analysis, software inventory, and policy enforcement. Tetration is part of the Cisco Zero Trust portfolio, which also includes solutions for securing the workforce and workplace. References:

The debug crypto isakmp sa command shows the status of the Internet Security Association and Key Management Protocol (ISAKMP) security associations (SAs). The output of this command indicates that the ISAKMP negotiation failed after several retransmissions. The most likely cause of this failure is a mismatch in the authentication key between the two peers. The authentication key is specified by the crypto isakmp key command and must be the same on both routers. If the authentication key is different, the ISAKMP messages cannot be decrypted and verified by the peers, resulting in an error. To fix this problem, the network administrator should verify and correct the authentication key on both routers and clear the existing ISAKMP SAs with the clear crypto isakmp sa command. References: 1, 2, 3, 4

The aaa server radius dynamic-author command enables authentication, authorization, and accounting (AAA) globally on the device so that Change of Authorization (CoA) is supported. CoA is a feature that allows an external AAA server to dynamically change the attributes of a user session after it is authenticated. For example, the AAA server can send a CoA request to reauthenticate a user, terminate a session, or apply a new policy. The aaa server radius dynamic-author command specifies the IP address and port number of the device that listens for CoA requests from the AAA server. The command also configures the shared secret key that is used to encrypt the communication between the device and the AAA server12. References := 1: Implementing and Operating Cisco Security Core Technologies (SCOR) v1.0, Module 3: Securing Networks with Cisco Firepower Next Generation Firewall, Lesson 3.2: Deploying Cisco Firepower Next-Generation Firewall, Topic 3.2.2: Cisco Firepower NGFW Device Management 2: Authentication, Authorization, and Accounting Configuration Guide, Cisco IOS Release 15SY - RADIUS Change of Authorization [Support] - Cisco3
