Explanation Explanation ETHOS is the Cisco file grouping engine. It allows us to group families of files together so if we see variants of a malware, we mark the ETHOS hash as malicious and whole families of malware are instantly detected.

Explanation
Domain name system (DNS) is the protocol that translates human-friendly URLs, such as securitytut.com, into IP addresses, such as 183.33.24.13. Because DNS messages are only used as the beginning of each communication and they are not intended for data transfer, many organizations do not monitor their DNS traffic for malicious activity. As a result, DNS-based attacks can be effective if launched against their networks. DNS tunneling is one such attack.
An example of DNS Tunneling is shown below:

The attacker incorporates one of many open-source DNS tunneling kits into an authoritative DNS nameserver (NS) and malicious payload.
2. An IP address (e.g. 1.2.3.4) is allocated from the attacker’s infrastructure and a domain name (e.g. attackerdomain.com) is registered or reused. The registrar informs the top-level domain (.com) nameservers to refer requests for attackerdomain.com to ns.attackerdomain.com, which has a DNS record mapped to 1.2.3.4
3. The attacker compromises a system with the malicious payload. Once the desired data is obtained, the payload encodes the data as a series of 32 characters (0-9, A-Z) broken into short strings (3KJ242AIE9, P028X977W,…).
4. The payload initiates thousands of unique DNS record requests to the attacker’s domain with each string as a part of the domain name (e.g. 3KJ242AIE9.attackerdomain.com). Depending on the attacker’s patience and stealth, requests can be spaced out over days or months to avoid suspicious network activity. 5. The requests are forwarded to a recursive DNS resolver. During resolution, the requests are sent to the attacker’s authoritative DNS nameserver, 6. The tunneling kit parses the encoded strings and rebuilds the exfiltrated data.

Explanation

Explanation
The command “snmp-server user user-name group-name [remote ip-address [udp-port port]] {v1 | v2c | v3 [encrypted] [auth {md5 | sha} auth-password]} [access access-list]” adds a new user (in this case “andy”) to an SNMPv3 group (in this case group name “myv3”) and configures a password for the user.
In the “snmp-server host” command, we need to:
+ Specify the SNMP version with key word “version {1 | 2 | 3}”
+ Specify the username (“andy”), not group name (“myv3”).
Note: In “snmp-server host inside …” command, “inside” is the interface name of the ASA interface through which the NMS (located at 10.255.254.1) can be reached.

We should scan emails using AntiVirus signatures to make sure there are no viruses attached in emails. Note: A virus signature is the fingerprint of a virus. It is a set of unique data, or bits of code, that allow it to be identified. Antivirus software uses a virus signature to find a virus in a computer file system, allowing to detect, quarantine, and remove the virus. SenderBase is an email reputation service designed to help email administrators research senders, identify legitimate sources of email, and block spammers. When the Cisco ESA receives messages from known or highly reputable senders, it delivers them directly to the end user without any content scanning. However, when the Cisco ESA receives email messages from unknown or less reputable senders, it performs antispam and antivirus scanning.

Web servers and email gateways are generally located in the DMZ so Note: The recipient access table (RAT), not to be confused with remote-access Trojan (also RAT), is a Cisco ESA term that defines which recipients are accepted by a public listener.
