Explanation

The Firepower System uses network discovery and identity policies to collect host, application, and user data for traffic on your network. You can use certain types of discovery and identity data to build a comprehensive map of your network assets, perform forensic analysis, behavioral profiling, access control, and mitigate and respond to the vulnerabilities and exploits to which your organization is susceptible.

The Cisco Advanced Malware Protection (AMP) solution enables you to detect and block malware, continuously analyze for malware, and get retrospective alerts. AMP for Networks delivers network-based advanced malware protection that goes beyond point-in-time detection to protect your organization across the entire attack continuum – before, during, and after an attack. Designed for Cisco Firepower® network threat appliances, AMP for Networks detects, blocks, tracks, and contains malware threats across multiple threat vectors within a single system. It also provides the visibility and control necessary to protect your organization against highly sophisticated, targeted, zero-day, and persistent advanced malware threats.

Cisco ESA uses a multilayer approach to fight viruses and malware. The first layer of defense consists of outbreak filters, which the appliance downloads from Cisco SenderBase. Outbreak filters use global threat intelligence and behavioral analysis to identify and block emerging threats before they reach the network. The second layer of defense consists of antivirus engines, which scan the message body and attachments for known viruses and malware. Cisco ESA supports multiple antivirus engines, such as Sophos, McAfee, and Cisco AMP. The Sophos engine is one of the default engines that Cisco ESA uses, along with McAfee. The Sophos engine provides fast and accurate detection of viruses and malware, and updates its signatures frequently. The other options are not features that are used to configure Cisco ESA with a multilayer approach to fight viruses and malware. A white list is a list of trusted senders or recipients that are exempt from spam or virus filtering. RAT is the Recipient Access Table, which is used to determine whether the appliance accepts or rejects messages to a recipient address. DLP is Data Loss Prevention, which is used to prevent sensitive or confidential data from leaving the network. References :=

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.

Phishing attacks are a type of social engineering that aim to trick users into revealing their personal or financial information, or installing malware on their devices. To control phishing attacks, users and organizations need to implement various preventive and reactive measures, such as:

Enable browser alerts for fraudulent websites. Most modern browsers have built-in features that can warn users when they visit a website that is suspected of being malicious or impersonating a legitimate entity. These alerts can help users avoid falling for phishing scams that use fake web pages to capture their credentials or other sensitive data. For example, Google Chrome has a Safe Browsing feature that displays a red warning page when users try to access a deceptive site. Users should always pay attention to these alerts and avoid proceeding to untrusted sites.

Implement email filtering techniques. Email is one of the most common channels for phishing attacks, as attackers can send spoofed messages that appear to come from trusted sources, such as banks, government agencies, or colleagues. Email filtering techniques can help block or flag suspicious emails based on various criteria, such as the sender’s address, the subject line, the content, or the attachments. For example, Microsoft Outlook has a Junk Email Filter that can move potential phishing emails to a separate folder or delete them automatically. Users should also be careful not to open or reply to any unsolicited or unexpected emails, especially those that ask for personal or financial information, or contain links or attachments.

Other mechanisms that can help control phishing attacks include:

Use strong passwords and enable two-factor authentication. Even if users fall victim to phishing attacks and reveal their passwords, they can still protect their accounts by using strong and unique passwords for each service, and enabling two-factor authentication (2FA) whenever possible. 2FA adds an extra layer of security by requiring users to enter a code or a token that is sent to their phone or email, or generated by an app, in addition to their password. This way, even if attackers obtain the password, they cannot access the account without the second factor.

Don’t ignore update messages. Users should always keep their operating systems, browsers, and applications updated with the latest security patches and fixes. These updates can help prevent phishing attacks that exploit known vulnerabilities or bugs in the software. Users should also use antivirus and antispyware software that can detect and remove malware that may be installed by phishing attacks.

Exercise caution when opening emails or clicking on links. Users should always be skeptical and vigilant when they receive emails or messages that ask them to take urgent or unusual actions, such as verifying their account, updating their payment information, or downloading a file. Users should also check the sender’s address, the spelling and grammar, and the URL of any links before clicking on them. Users can hover over the link to see the actual destination, or use a link scanner tool, such as VirusTotal, to check if the link is malicious or not.

Cisco Advanced Malware Protection (AMP) for endpoints can be seen as a replacement for the traditional antivirus solution. It is a next generation, cloud delivered endpoint protection platform (EPP), and advanced endpoint detection and response (EDR). Providing Protection – Detection Response

While Cisco Umbrella can enforce security at the DNS-, IP-, and HTTP/S-layer, this report does not require that blocking is enabled and only monitors your DNS activity. Any malicious domains requested and IPs resolved are indicators of compromise (IOC).

A Simple Custom Detection List is a feature of Cisco AMP for Endpoints that allows administrators to create a list of SHA-256 hashes of files that they want to detect, block, and quarantine on their endpoints. The list can be applied to a policy and the connectors will synchronize with the latest changes. However, the list only works with the exact SHA-256 hashes that are provided, and it does not detect any variations or modifications of the files. Therefore, if the malicious file abc428565580xyz.exe has been altered in any way, such as by changing its name, size, or content, the Simple Custom Detection List will not be able to recognize it as a threat. To ensure detection of the malicious file, the administrator must upload the SHA-256 hash of the current version of the file to the Simple Custom Detection List, or use another method that can detect file variations, such as an Advanced Custom Detection List or Cisco Threat Grid. References :=

EPP and EDR are two types of endpoint security solutions that have different goals and capabilities. EPP stands for endpoint protection platform, which is a suite of technologies that work together to prevent, detect, and remediate security threats on endpoints. EPP solutions use techniques such as antivirus, firewall, application control, and patch management to block known and unknown malware and malicious activity. EDR stands for endpoint detection and response, which is a solution that provides real-time visibility into endpoint activities and enables security teams to detect, investigate, and respond to advanced threats that may have bypassed EPP defenses. EDR solutions use techniques such as behavioral analysis, threat intelligence, and incident response to flag offending files at the first sign of malicious behavior, contain and isolate compromised endpoints, and remediate the damage caused by the attack. Therefore, the correct answer is D, as having an EDR solution gives an engineer the capability to flag offending files at the first sign of malicious behavior. The other options are incorrect because:

A is false, as EPP focuses primarily on threats that have evaded front-line defenses that entered the environment, not EDR.

B is false, as having an EPP solution allows an engineer to detect, investigate, and remediate modern threats, not EDR.

C is false, as EDR focuses on detection and response at the endpoint level, not prevention at the perimeter. References:

A Trojan malware attack is a type of malicious code or software that disguises itself as a legitimate program or file to trick users into executing it. Once executed, the Trojan can perform various harmful actions on the infected system or network, such as stealing data, deleting files, or installing other malware. There are different types of Trojan malware attacks, depending on their purpose and behavior. Two common types are:

Rootkit: A rootkit is a type of Trojan that hides itself and other malware from detection and removal by antivirus software or system tools. A rootkit can modify the operating system or the firmware of the device to gain persistent and privileged access to the system. A rootkit can also intercept and manipulate system calls, network traffic, or user input to conceal its activities or redirect them to malicious servers.

Backdoor: A backdoor is a type of Trojan that creates a secret or unauthorized access point to the infected system or network. A backdoor can allow an attacker to remotely control the system, execute commands, upload or download files, or monitor the system activity. A backdoor can also be used to install other malware or launch further attacks on other systems or networks.
