Explanation

There are two possible methods to accomplish the redirection of traffic to Cisco WSA: transparent proxy mode and explicit proxy mode.

In a transparent proxy deployment, a WCCP v2-capable network device redirects all TCP traffic with a

destination of port 80 or 443 to Cisco WSA, without any configuration on the client. The transparent proxy

deployment is used in this design, and the Cisco ASA firewall is used to redirect traffic to the appliance because all of the outbound web traffic passes through the device and is generally managed by the same operations staff who manage Cisco WSA.

Explanation

To configure an NTP enabled router to require authentication when other devices connect to it, use the

following commands:

NTP_Server(config)#ntp authentication-key 2 md5 securitytut

NTP_Server(config)#ntp authenticate

NTP_Server(config)#ntp trusted-key 2

Then you must configure the same authentication-key on the client router:

NTP_Client(config)#ntp authentication-key 2 md5 securitytut

NTP_Client(config)#ntp authenticate

NTP_Client(config)#ntp trusted-key 2

NTP_Client(config)#ntp server 10.10.10.1 key 2

Note: To configure a Cisco device as a NTP client, use the command ntp server < IP address > . For example:

Router(config)#ntp server 10.10.10.1. This command will instruct the router to query 10.10.10.1 for the time.

Explanation

All IKE policies on the device are sent to the remote peer regardless of what is in the selected policy section.

The first IKE Policy matched by the remote peer will be selected for the VPN connection. Choose which policy is sent first using the priority field. Priority 1 will be sent first.

Explanation

In its essence, FlexVPN is the same as DMVPN. Connections between devices are still point-to-point GRE tunnels, spoke-to-spoke connectivity is still achieved with NHRP redirect message, IOS routers even run the same NHRP code for both DMVPN and FlexVPN, which also means that both are Cisco’s proprietary technologies.

 Mobile Device Management (MDM) is a solution that allows an organization to manage, monitor, and secure mobile devices such as smartphones, tablets, and laptops. MDM provides two main advantages to an organization with regards to device management:

Asset inventory management: MDM helps an organization keep track of all the mobile devices that are connected to its network, including their location, status, configuration, and usage. MDM also enables an organization to remotely wipe or lock devices that are lost, stolen, or compromised, preventing data loss and unauthorized access. Asset inventory management helps an organization optimize its resources, reduce costs, and comply with regulations12.

Allowed application management: MDM allows an organization to control what applications can be installed and run on the mobile devices, as well as how they can access and share data. MDM can also push updates and patches to the devices, ensuring that they are always running the latest and most secure versions of the applications. Allowed application management helps an organization enhance security, productivity, and performance of the mobile devices34.

Explanation

Dynamic ARP inspection (DAI) is a security feature that validates ARP packets in a network. It intercepts, logs, and discards ARP packets with invalid IP-to-MAC address bindings. This capability protects the network from certain man-in-the-middle attacks. After enabling DAI, all ports become untrusted ports.

Endpoint Detection and Response (EDR) continuously records endpoint activity, applies behavioral analytics to suspicious actions, supports investigation, and enables response actions such as isolating or remotely containing a compromised host. This provides visibility into previously unknown or zero-day behavior while integrating automated prevention and response for known threats. An Endpoint Protection Platform can block known malware, but pairing it only with host intrusion detection does not provide the complete behavioral investigation and remote-containment capability stated. Offline antivirus updates emphasize signature maintenance and cannot deliver live investigation or console-driven containment. A Secure Email Gateway protects the email channel and can sandbox attachments, but it does not monitor and contain general endpoint activity. Therefore, EDR with behavioral analytics and remote containment is the only solution satisfying all parts of the requirement. Cisco EDR overview

Explanation

Cisco Tetration platform studies the behavior of the various processes and applications in the workload,

measuring them against known bad behavior sequences. It also factors in the process hashes it collects. By

studying various sets of malwares, the Tetration Analytics engineering team deconstructed it back into its basic

building blocks. Therefore, the platform understands clear and crisp definitions of these building blocks and

watches for them.

The various suspicious patterns for which the Cisco Tetration platform looks in the current release are:

+ Shell code execution: Looks for the patterns used by shell code.

+ Privilege escalation: Watches for privilege changes from a lower privilege to a higher privilege in the process

lineage tree.

+ Side channel attacks: Cisco Tetration platform watches for cache-timing attacks and page table fault bursts.

Using these, it can detect Meltdown, Spectre, and other cache-timing attacks.

+ Raw socket creation: Creation of a raw socket by a nonstandard process (for example, ping).

+ User login suspicious behavior: Cisco Tetration platform watches user login failures and user login methods.

+ Interesting file access: Cisco Tetration platform can be armed to look at sensitive files.

+ File access from a different user: Cisco Tetration platform learns the normal behavior of which file is

accessed by which user.

+ Unseen command: Cisco Tetration platform learns the behavior and set of commands as well as the lineage

of each command over time. Any new command or command with a different lineage triggers the interest of the

Tetration Analytics platform.

Session hijacking succeeds when an attacker obtains or abuses a valid session identifier, commonly one stored in a browser cookie. Secure cookie controls directly protect that credential. The Secure attribute limits transmission to HTTPS, reducing exposure over cleartext connections; HttpOnly prevents client-side scripts from reading the cookie; and an appropriate SameSite setting limits cross-site sending. Strong session handling should also use unpredictable identifiers, rotation after authentication, expiration, and server-side revocation. Input validation primarily mitigates injection vulnerabilities. Least privilege can reduce the damage after compromise but does not stop theft of a session token. Anti-CSRF tokens prevent unauthorized cross-site requests made through a victim’s authenticated browser, but they are not the primary protection against capture of the session cookie itself. Therefore, secure cookies are the best answer. RFC 6265 HTTP cookie specification

Southbound APIs are used to communicate between the SDN Controller and the switches and routers of the network. They can be open-source or proprietary. They facilitate control over the network and enable the SDN Controller to dynamically make changes according to real-time demands and needs. OpenFlow and OpFlex are two examples of southbound APIs. OpenFlow, which was developed by the Open Networking Foundation (ONF), is the first and probably most well-known southbound interface. OpenFlow defines the way the SDN Controller should interact with the forwarding plane to make adjustments to the network, so it can better adapt to changing business requirements. With OpenFlow, entries can be added and removed to the internal flow-table of switches and routers to make the network more responsive to real-time traffic demands. OpFlex, which was proposed by Cisco, is another southbound interface that uses a declarative model to communicate policies and state between the controller and the network devices. OpFlex allows the network devices to retain some intelligence and autonomy, while still being managed by the controller. OpFlex is designed to be flexible and extensible, and can support different types of network devices and services. Services running over the network, external application APIs, and applications running over the network are not southbound APIs, as they do not directly communicate between the controller and the network devices. Therefore, the correct answer is B and E. References :=

Explanation

Cisco Umbrella protects users from accessing malicious domains by proactively analyzing and blocking unsafe destinations – before a connection is ever made. Thus it can protect from phishing attacks by blocking suspicious domains when users click on the given links that an attacker sent. Cisco Umbrella roaming protects your employees even when they are off the VPN.

 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:

To achieve the goal of excluding some servers from the VPN tunnel and accessing them directly, the engineer must modify the group policy that is applied to the remote access VPN users. The group policy contains the settings for split tunneling, which is a feature that allows the VPN client to route some traffic through the VPN tunnel and some traffic directly to the internet. Split tunneling can be configured based on the destination IP address, the application, or the domain name of the traffic. By modifying the group policy, the engineer can specify which servers or networks should be excluded from the VPN tunnel and accessed directly by the VPN client. This can improve the performance and efficiency of the VPN connection, as well as reduce the load on the VPN gateway and the corporate network. However, split tunneling also introduces some security risks, such as exposing the VPN client to internet threats, bypassing the corporate firewall and security policies, and leaking sensitive data. Therefore, the engineer must carefully evaluate the trade-offs and best practices of using split tunneling for remote access VPNs. References :=
