GETVPN and IPsec are both VPN technologies that use ESP (Encapsulating Security Payload) to encrypt and authenticate data packets. However, they differ in the following aspects:

GETVPN uses a group IPSec security paradigm, which means that all group members share the same IPSec SA (Security Association) and can communicate with each other without having to establish point-to-point tunnels. IPsec, on the other hand, uses a pair-wise IPSec security paradigm, which requires each pair of devices to negotiate and maintain their own IPSec SAs and tunnels.

GETVPN uses GDOI (Group Domain of Interpretation) as a key management protocol, which allows a Key Server (KS) to distribute the encryption keys and policies to all group members. IPsec uses IKE (Internet Key Exchange) as a key management protocol, which involves two phases of negotiation between each pair of devices to establish the IPSec SAs.

GETVPN supports multicast traffic without the need for GRE (Generic Routing Encapsulation) tunneling, as it preserves the original IP header of the packet. IPsec does not support multicast traffic natively, and requires GRE tunneling to encapsulate the multicast packets with a new IP header.

GETVPN relies on the underlying WAN routing to deliver the encrypted packets to the destination, as it does not create any overlay routing. IPsec creates an overlay routing, which may introduce additional latency and complexity.

Cisco Get VPN vs DMVPN: Difference and Comparison

What is a difference between GETVPN and IPsec?

Explanation

Diffie Hellman (DH) uses a private-public key pair to establish a shared secret, typically a symmetric key. DH is not a symmetric algorithm – it is an asymmetric algorithm used to establish a shared secret for a symmetric key algorithm.

Explanation

Posture is a service in Cisco Identity Services Engine (Cisco ISE) that allows you to check the state, also

known as posture, of all the endpoints that are connecting to a network for compliance with corporate security

policies.

A posture policy is a collection of posture requirements that are associated with one or more identity groups and

operating systems.

Posture-policy requirements can be set to mandatory, optional, or audit types in posture policies.

+ If a mandatory requirement fails, the user will be moved to Non-Compliant state

+ If an optional requirement fails, the user is allowed to skip the specified optional requirements and the user

is moved to Compliant state

This Qdid not clearly specify the type of posture policy requirement (mandatory or optional) is not met so the

user can be in Non-compliant or compliant state. But “noncompliant” is the best answer here.

Cisco Cognitive Threat Analytics helps you quickly detect and respond to sophisticated, clandestine attacks that are already under way or are attempting to establish a presence within your environment. The solution automatically identifies and investigates suspicious or malicious web-based traffic. It identifies both potential and confirmed threats, allowing you to quickly remediate the infection and reduce the scope and damage of an attack, whether it’s a known threat campaign that has spread across multiple organizations or a unique threat you’ve never seen before.

Detection and analytics features provided in Cognitive Threat Analytics are shown below:

+ Data exfiltration: Cognitive Threat Analytics uses statistical modeling of an organization’s network to identify anomalous web traffic and pinpoint the exfiltration of sensitive data. It recognizes data exfiltration even in HTTPS-encoded traffic, without any need for you to decrypt transferred content

+ Command-and-control (C2) communication: Cognitive Threat Analytics combines a wide range of data, ranging from statistics collected on an Internet-wide level to host-specific local anomaly scores. Combining these indicators inside the statistical detection algorithms allows us to distinguish C2 communication from benign traffic and from other malicious activities. Cognitive Threat Analytics recognizes C2 even in HTTPSencoded or anonymous traffic, including Tor, without any need to decrypt transferred content, detecting a broad

range of threats

The Cisco Endpoint IoC feature is a powerful incident response tool for scanning of post-compromise indicators across multiple computers. Endpoint IoCs are imported through the console from OpenIOC-based files written to trigger on file properties such as name, size, hash, and other attributes and system properties such as process information, running services, and Windows Registry entries. The IoC syntax can be used by incident responders to find specific artifacts or use logic to create sophisticated, correlated detections for families of malware. Endpoint IoCs have the advantage of being portable to share within your organization or in industry vertical forums and mailing lists. The Endpoint IoC scanner is available in AMP for Endpoints Windows Connector versions 4 and higher. Running Endpoint IoC scans may require up to 1 GB of free drive space. The Endpoint IoC feature is based on the openioc.com framework, which is an open standard for sharing threat intelligence. References:

Intra-EPG Isolation is an option to prevent physical or virtual endpoint devices that are in the same base EPG or microsegmented (uSeg) EPG from communicating with each other. By default, endpoint devices included in the same EPG are allowed to communicate with one another.

Explanation

The command crypto isakmp key cisco address 1.2.3.4 authenticates the IP address of the 1.2.3.4 peer by using the key cisco. The address of “0.0.0.0” will authenticate any address with this key

Group Encrypted Transport VPN (GET VPN) is used to implement secure VPN connectivity among company branches over a private IP cloud with any-to-any scalable connectivity. GET VPN provides a way to encrypt traffic between sites without the need for point-to-point tunnels, supporting efficient, scalable, and secure communication across a broad network infrastructure.
