MAC Address D. Padding E. Pad Length F. MAC spoofing B. CAM overflow…. Correct Answer: A Explanation. How many times was a read-only string used to attempt a write operation? Other class-maps within a policy-map can also be configured to drop unwanted traffic.

The log option can be added with drop for syslog notification that traffic was dropped by the firewall. Pass — This action allows the router to forward traffic from one zone to another. The pass action does not track the state of connections or sessions within the traffic.

Pass only allows the traffic in one direction. A corresponding policy must be applied to allow return traffic to pass in the opposite direction. However, most application traffic is better handled in the ZFW with the inspect action.

Inspect—The inspect action offers state-based traffic control. For example, if traffic from the private zone to the Internet zone in the earlier example network is inspected, the router maintains connection or session information for TCP and User Datagram Protocol UDP traffic. Therefore, the router permits return traffic sent from Internet-zone hosts in reply to private zone connection requests. Also, inspect can provide application inspection and control for certain service protocols that might carry vulnerable or sensitive application traffic.

Threat mitigation B. Risk analysis C. Botnet mitigation D. Overt and covert channels Correct Answer: A Explanation. The isolated port can communicate only with the promiscuous port. The isolated port can communicate with other isolated ports and the promiscuous port.

The isolated port can communicate only with community ports. The isolated port can communicate only with other isolated ports. ACS servers can be clustered to provide scalability. ACS can query multiple Active Directory domains. ACS can use only one authorization profile to allow or deny requests.

If a supplicant supplies incorrect credentials for all authentication methods configured on the switch, how will the switch respond?

The supplicant will fail to advance beyond the webauth method. The switch will cycle through the configured authentication methods indefinitely. The authentication attempt will time out and the switch will place the port into the unauthorized state. The authentication attempt will time out and the switch will place the port into VLAN If it asks about interface level then choose that. Choose two. QoS B. The ISE agent must be installed on the device. The device must be connected to the network when the lock command is executed.

The user must approve the locking action. The organization must implement an acceptable use policy allowing device locking. Arp Poisoning B. Modify Traffic in transit C. Cisco ASA c. Cisco ISR G2 routers d. Cisco WSA 7. Which of the following features are supported by the Cisco WSA? File reputation b.

File sandboxing c. Layer 4 traffic monitor d. Real-time e-mail scanning e. Third-party DLP integration 8. Multiple context mode b. Explicit proxy mode c. Transparent proxy mode d. Cisco provides cloud-based, hybrid, and on-premises ESA-based solutions that can help protect any dynamic environment. This section introduces these solutions and technologies explaining how users can use threat intelligence to detect, analyze, and protect against both known and emerging threats.

E-mail-Based Threats There are several types of e-mail-based threats. E-mail spam continuous to be a major threat because 18 it can be used to spread malware. These phishing e-mails are directed to specific individuals or organizations. For instance, an attacker may perform a passive reconnaissance on the individual or organization by gathering information from social media sites for example, Twitter, LinkedIn, Facebook and other online resources.

Then the attacker may tailor a more directed and relevant message to the victim increasing the probability of such user being fooled to follow a malicious link, click an attachment containing malware, or simply reply to the e-mail providing sensitive information.

There is another phishing-based attack called whaling. These attacks specifically target executives and high-profile users within a given organization. Cisco Cloud E-mail Security Cisco cloud e-mail security provides a cloud-based solution that allows companies to out- source the management of their e-mail security management. The service provides e-mail security instances in multiple Cisco data centers to enable high availability.

Figure illus- trates the Cisco cloud e-mail security solution. In Figure , three organizations a large enterprise, a university, and a small- to medium- size business leverage the Cisco hosted cloud environment. The solution also supports mobile workers.

This hybrid solution helps Cisco customers reduce their on-site e-mail security foot- print, outsourcing a portion of their e-mail security to Cisco, while still allowing them to maintain control of confidential information within their physical boundaries.

Many organi- zations need to stay compliant to many regulations that may require them to keep sensitive data physically on their premises. The Cisco hybrid e-mail security solution allows network security administrators to remain compliant and to maintain advanced control with encryp- tion, data loss prevention DLP , and on-site identity-based integration.

The Cisco AsyncOS supports numerous features that will help mitigate e-mail-based threats. Cisco partnered with Sophos and McAfee, supporting their antivirus scanning engines. Cisco ESAs that are only running outbound messages and are not running antispam and antivirus may experience a significant performance decline.

The administrator can configure an encryption policy on the Cisco ESA and use a local key server or hosted key service to encrypt the message. The Cisco ESA acts as the e-mail gateway to the organization, handling all e-mail connec- tions, accepting messages, and relaying them to the appropriate systems.

The Cisco ESA can service e-mail connections from the Internet to users inside your network, and from systems inside your network to the Internet. A listener defines an e-mail processing service that is configured on an interface in the Cisco ESA. Listeners apply to e-mail entering the appliance from either the Internet or from internal systems. Figure illustrates the concept of Cisco ESA listeners.

The listener properties must also indicate whether it is a public or a private listener. An administrator can specify which remote hosts can connect to the listener. Log in to the Cisco ESA. The default username is admin, and the default pass- word is ironport.

Step 2. Are you sure you wish to continue? Management PrivateNet PublicNet Hostnames such as "example. Partial hostnames such as ". Usernames such as "postmaster " are allowed. Full email addresses such as "joe example. Separate multiple entries with commas. Rate limiting defines the maximum number of recipients per hour you are willing to receive from a remote domain.

Defaults have been set for a Public listener. Defaults have been set for a Private listener. System setup is complete.

For advanced configuration, please refer to the User Guide. The domain name of securemeinc. To verify the configuration, you can use the mailconfig command to send a test e-mail con- taining the system configuration data that was entered in the System Setup Wizard, as shown in Example Example Verifying the Configuration with the mailconfig Command mail3. Separate multiple addresses with commas. Nowadays, you can download malware through compromised legitimate websites, including social media sites, advertise- ments in news and corporate sites, gaming sites, and many more.

Cisco has developed several tools and mechanisms to help their customers combat these threats. Both solutions enable malware detection and blocking, continuous monitoring, and retrospective alerting. Cisco CWS Cisco CWS is a cloud-based security service from Cisco that provides worldwide threat intelligence, advanced threat defense capabilities, and roaming user protection.

In addition, the scanning is offloaded from the hardware appliances to the cloud, reducing the impact to hardware utilization and reducing network latency.

Figure illustrates how the transparent proxy functionality through a connector works. The following steps explain how Cisco CWS protects the corporate users at the branch office: 1.

An internal user makes an HTTP request to an external website securemeinc. It notices that securemeinc. Cisco CWS blocks the request to the malicious site. This threat intel- ligence helps security professionals to stop threats before they enter the corporate network, while also enabling file reputation and file sandboxing to identify threats during an attack.

Retrospective attack analysis allows security administrators to investigate and provide pro- tection after an attack when advanced malware might have evaded other layers of defense. WCCP is a protocol originally developed by Cisco, but several other vendors have integrated it in their products to allow clustering and transparent proxy deployments on networks using Cisco infrastructure devices routers, switches, firewalls, and so on.

In addition, you can use the ACS server as a destination for logging called accounting , noting which users access the system and what they do while there. An easy way to remember is that the S means secure.

To the end user such as you or I, it represents a secure connection to the server, and to the correct server. Once there, the browser requests that the web server identify itself. Be aware that all of this that is about to happen is occurring in the background and does not require user intervention. The server sends the browser a copy of its digital certificate, which may also be called an SSL certificate.

When the browser receives the certificate, it checks whether it trusts the certificate. The browser decides whether it is trusted by looking at the digital signature of the CA that is on the certificate; using the method for verifying a digital signature discussed earlier, the browser determines the certificate is valid based on the signature of the CA or is not valid.

If the signature is not valid, or at least if our browser does not think the certificate is valid, a pop-up is usually presented to the user asking whether the user wants to proceed.
