Eccouncil Certified Cybersecurity Technician 212-82 CCT Exam Questions

Answer : A

Quantum cryptography is the encryption mechanism demonstrated in the above scenario. Quantum cryptography is a branch of cryptography that uses quantum physics to secure data transmission and communication. Quantum cryptography encrypts data by using a sequence of photons that have a spinning trait, called polarization, while traveling from one end to another. These photons keep changing their shapes, called states, during their course through filters: vertical, horizontal, forward slash, and backslash. Quantum cryptography ensures that any attempt to intercept or tamper with the data will alter the quantum states of the photons and be detected by the sender and receiver . Homomorphic encryption is a type of encryption that allows computations to be performed on encrypted data without decrypting it first. Rivest Shamir Adleman (RSA) encryption is a type of asymmetric encryption that uses two keys, public and private, to encrypt and decrypt data. Elliptic curve cryptography (ECC) is a type of asymmetric encryption that uses mathematical curves to generate keys and perform encryption and decryption.

Answer : B

Performing a vulnerability analysis on a web application involves identifying specific security weaknesses. In this case, the WASC ID 9 refers to 'Application Error Disclosure.'

Vulnerability Description:

Application Error Disclosure: This vulnerability occurs when a web application reveals too much information about internal errors, potentially aiding attackers in crafting specific attacks against the system.

Detection and Mitigation:

Error Handling: Ensure that error messages do not expose sensitive information and provide only necessary details to the end-user.

Logging: Detailed error information should be logged securely for internal review without being exposed to users.

OWASP Top Ten Web Application Security Risks: OWASP

WASC Threat Classification: WASC ID 9

Answer : C

Exception handling is a secure application design principle that states that the application should handle errors and exceptions gracefully and securely, without exposing sensitive information or compromising the system's functionality. Exception handling can help prevent attackers from exploiting errors or exceptions to gain access to data or resources or cause denial-of-service attacks. In the scenario, Miguel identified a flaw in the end-point communication that can disclose the target application's data, which means that the application did not meet the exception handling principle.

Answer : B

Analyzing the executable file to determine the Linker Info value involves examining the file's properties. The Linker Info is part of the metadata within an executable file, often viewed using tools such as PE Explorer, CFF Explorer, or using command-line tools like dumpbin in Windows or readelf in Unix-like systems. Here's a step-by-step approach:

Locate the file: Ensure that ShadowByte.exe is in the Downloads folder.

Use a tool to inspect the executable:

PE Explorer/CFF Explorer: Open the file in one of these tools and navigate to the sections that display header information.

Command-line: Use dumpbin /HEADERS ShadowByte.exe on Windows or readelf -h ShadowByte.exe on Unix-like systems.

Identify the Linker Info: Look for the 'Linker Version' or similar field in the output.

Interpret the value: In this case, the correct Linker Info value is 2.25.

Answer : B

The correct answer is B, as it identifies the type of attack performed by Thomas in the above scenario. Eavesdropping is a type of attack that involves intercepting and listening to the communication between two parties without their knowledge or consent. Thomas performed eavesdropping by sniffing communication between the administrator and an application server to retrieve the admin credentials. Option A is incorrect, as it does not identify the type of attack performed by Thomas in the above scenario. Vishing is a type of attack that involves using voice calls to trick people into revealing sensitive information or performing malicious actions. Thomas did not use voice calls but sniffed network traffic. Option C is incorrect, as it does not identify the type of attack performed by Thomas in the above scenario. Phishing is a type of attack that involves sending fraudulent emails or messages that appear to be from legitimate sources to lure people into revealing sensitive information or performing malicious actions. Thomas did not send any emails or messages but sniffed network traffic. Option D is incorrect, as it does not identify the type of attack performed by Thomas in the above scenario. Dumpster diving is a type of attack that involves searching through trash or discarded items to find valuable information or resources. Thomas did not search through trash or discarded items but sniffed network traffic.

Answer : B

A circuit-level gateway is a type of firewall that works at the session layer of the OSI model and monitors the TCP handshake between hosts to determine whether a requested session is legitimate.It does not inspect the contents of each packet, but rather relies on the session information to filter traffic

Answer : A

To effectively trace unauthorized activities within TechTonic's Windows-based server farm, the best strategy is:

Centralized Logging:

Aggregation: Collect all system logs in a centralized logging server. This ensures that all log data is stored in one place, making it easier to manage and analyze.

Correlation: Correlate logs from different sources to identify patterns and anomalies that might indicate unauthorized activities.

Pattern-Detection Algorithms:

Automated Analysis: Use algorithms to automatically detect patterns that are indicative of security breaches. This can include machine learning models trained to recognize signs of intrusion.

Real-Time Alerts: Set up real-time alerts for suspicious activities identified by the pattern-detection algorithms, enabling swift responses to potential threats.
