A Cisco ESA administrator was notified that a user was not receiving emails from a specific domain. After reviewing the mail logs, the sender had a negative sender-based reputation score.

What should the administrator do to allow inbound email from that specific domain?

  1. Create a new inbound mail policy with a message filter that overrides Talos.
  2. Ask the user to add the sender to the email application's allow list.
  3. Modify the firewall to allow emails from the domain.
  4. Add the domain into the allow list.

Answer(s): D

Explanation:

The allow list is a feature that allows Cisco ESA to accept messages from specific email addresses or domains, regardless of their sender-based reputation score or other reputation filters. To allow inbound email from that specific domain, the administrator should add the domain into the allow list on Cisco ESA, which can be done from the web user interface by selecting Security Services > Safelist/Blocklist and clicking Add Entry.
The other options are not valid solutions to allow inbound email from that specific domain, because they do not affect the sender-based reputation score or the reputation filters on Cisco ESA.

An email containing a URL passes through the Cisco ESA that has content filtering disabled for all mail policies. The sender is sampleuser@test1.com, the recipients are testuser1@test2.com, testuser2@test2.com, testuser3@test2.com, and mailer1@test2.com. The subject of the email is Test Document395898847. An administrator wants to add a policy to ensure that the Cisco ESA evaluates the web reputation score before permitting this email.

Which two criteria must be used by the administrator to achieve this? (Choose two.)

  1. Subject contains Test Document"
  2. Sender matches test1.com
  3. Email body contains a URL
  4. Date and time of email
  5. Email does not match mailer1@test2.com

Answer(s): B,C

Explanation:

Web reputation score is a feature that allows Cisco ESA to evaluate the reputation of URLs in messages based on real-time data from Talos intelligence and apply appropriate actions, such as block, quarantine, or deliver.
To ensure that Cisco ESA evaluates the web reputation score before permitting this email, the administrator should use two criteria to create a content filter or message filter that matches this email and applies an action of "check web reputation":
Sender matches test1.com, which means that the sender's domain name is test1.com. Email body contains a URL, which means that the message body has one or more URLs in it. The other options are not valid criteria to ensure that Cisco ESA evaluates the web reputation score before permitting this email, because they do not match this email or they are not relevant to web reputation score.

A recent engine update was pulled down for graymail and has caused the service to start crashing. It is critical to fix this as quickly as possible.

What must be done to address this issue?

  1. Roll back to a previous version of the engine from the Services Overview page.
  2. Roll back to a previous version of the engine from the System Health page.
  3. Download another update from the IMS and Graymail page.
  4. Download another update from the Service Updates page.

Answer(s): A


Reference:

https://www.cisco.com/c/en/us/td/docs/security/esa/esa11- 1/user_guide/b_ESA_Admin_Guide_11_1/b_ESA_Admin_Guide_11_1_chapter_0100010.html#task _9F07A032042F48C6AEDB69D325CD3C5F

To address this issue, the administrator should roll back to a previous version of the engine from the Services Overview page on Cisco ESA. This will restore the functionality of graymail service and prevent it from crashing.
The Services Overview page allows the administrator to view and manage various services on Cisco ESA, such as antivirus, outbreak filters, graymail, etc., and perform actions such as enable/disable, update, or roll back.
The other options are not valid solutions to address this issue, because they do not allow the administrator to roll back to a previous version of the engine for graymail service.
