What tests would you perform to determine whether his computer is infected? A. Upload the file to VirusTotal. B. You do not check; rather, you immediately restore a previous snapshot of the operating system. C. Use ExifTool and check for malicious content. D. Use netstat and check for outgoing connections to strange IP addresses or domains.

D. Use netstat and check for outgoing connections to strange IP addresses or domains; The question asks how we would determine if his PC is infected. It does not ask how we'll determine if the file is corrupt or malicious. The only PC tests of these options is D.

Calvin, a grey-hat hacker, targets a web application that has design flaws in its authentication mechanism.

Jane is working as a security professional at CyberSol Inc. She was tasked with ensuring the authentication and integrity of messages being transmitted in the corporate network. To encrypt the messages, she implemented a security model in which every user in the network maintains a ring of public keys. In this model, a user needs to encrypt a message using the receiver's public key, and only the receiver can decrypt the message using their private key.What is the security model implemented by Jane to secure corporate messages? A. Zero trust network B. Secure Socket Layer (SSL) C. Transport Layer Security (TLS) D. Web of trust (WOT)

D. Web of trust (WOT);

When considering how an attacker may exploit a web server, what is web server footprinting? A. When an attacker creates a complete profile of the site's external links and file structures B. When an attacker uses a brute-force attack to crack a web-server password C. When an attacker implements a vulnerability scanner to identity weaknesses D. When an attacker gathers system-level data, including account details and server names

D. When an attacker gathers system-level data, including account details and server names; By performing web server footprinting, an attacker can gather valuable system-level data such as account details, OSs, software versions, server names, and database schema details.

Session splicing is an IDS evasion technique in which an attacker delivers data in multiple, small sized packets to the target computer, making it very difficult for anIDS to detect the attack signatures. Which tool can be used to perform session splicing attacks? A. tcpsplice B. Burp C. Hydra D. Whisker

D. Whisker

George is a security professional working for iTech Solutions. He was tasked with securely transferring sensitive data of the organization between industrial systems. In this process, he used a short-range communication protocol based on the IEEE 203.15.4 standard. This protocol is used in devices that transfer data infrequently at a low rate in a restricted area, within a range of 10-100 m. What is the short-range wireless communication technology George employed in the above scenario? A. LPWAN B. MQTT C. NB-IoT D. Zigbee

D. Zigbee

Which of the following Google advanced search operators helps an attacker in gathering information about websites that are similar to a specified target URL? A. [inurl:] B. [info:] C. [site:] D. [related:]

D. [related:]

You have been authorized to perform a penetration test against a website. You want to use Google dorks to footprint the site but only want results that show file extensions. What Google dork operator would you use? A. inurl B. site C. ext D. filetype

D. filetype

You are a Network Security Officer. You have two machines. The first machine (192.168.0.99) has snort installed, and the second machine (192.168.0.150) has kiwi syslog installed. You perform a syn scan in your network, and you notice that kiwi syslog is not receiving the alert message from snort. You decide to run wireshark in the snort machine to check if the messages are going to the kiwi syslog machine. What Wireshark filter will show the connections from the snort machine to kiwi syslog machine? A. tcp.srcport== 514 && ip.src= = 192.168.0.99 B. tcp.srcport== 514 && ip.src= = 192.168.150 C. tcp.dstport== 514 && ip.dst= = 192.168.0.99 D. tcp.dstport== 514 && ip.dst= = 192.168.0.150

D. tcp.dstport== 514 && ip.dst= = 192.168.0.150; the destination IP address should be set to that of the kiwi syslog machine and the dest port should be 514.
