Which strategy best mitigates session hijacking?
An attacker decided to crack the passwords used by industrial control systems. In this process, he employed a loop strategy to recover these passwords. He used one character at a time to check whether the first character entered is correct; if so, he continued the loop for consecutive characters. If not, he terminated the loop. Furthermore, the attacker checked how much time the device took to finish one complete password authentication process, through which he deduced how many characters entered are correct.
What is the attack technique employed by the attacker to crack the passwords of the industrial control systems?
As a securing consultant, what are some of the things you would recommend to a company to ensure DNS security?
Which of the following tools can be used to perform a zone transfer?
Which algorithm best protects encrypted traffic patterns?
During an IDS audit, you notice numerous alerts triggered by legitimate user activity. What is the most likely cause?
A financial institution's online banking platform is experiencing intermittent downtime caused by a sophisticated DDoS attack that combines SYN floods and HTTP GET floods from a distributed botnet. Standard firewalls and load balancers cannot mitigate the attack without affecting legitimate users. To protect their infrastructure and maintain service availability, which advanced mitigation strategy should the institution implement?
On performing a risk assessment, you need to determine the potential impacts when some of the critical business processes of the company interrupt its service.
What is the name of the process by which you can determine those critical businesses?
Sam is working as a system administrator In an organization. He captured the principal characteristics of a vulnerability and produced a numerical score to reflect Its severity using CVSS v3.0 to property assess and prioritize the organization's vulnerability management processes. The base score that Sam obtained after performing cvss rating was 4.0. What is the CVSS severity level of the vulnerability discovered by Sam in the above scenario?
Which of the following antennas is commonly used in communications for a frequency band of 10 MHz to VHF and UHF?
While performing a security audit of a web application, an ethical hacker discovers a potential vulnerability.
The application responds to logically incorrect queries with detailed error messages that divulge the underlying database's structure. The ethical hacker decides to exploit this vulnerability further. Which type of SQL Injection attack is the ethical hacker likely to use?
Which of the following DoS tools is used to attack target web applications by starvation of available sessions on the web server? The tool keeps sessions at halt using never-ending POST transmissions and sending an arbitrarily large content-length header value.
These hackers have limited or no training and know how to use only basic techniques or tools. What kind of hackers are we talking about?
Robert, a professional hacker, is attempting to execute a fault injection attack on a target IoT device. In this process, he injects faults into the power supply that can be used for remote execution, also causing the skipping of key instructions. He also injects faults into the clock network used for delivering a synchronized signal across the chip.
Which of the following types of fault injection attack is performed by Robert in the above scenario?
Steve, a scientist who works in a governmental security agency, developed a technological solution to identify people based on walking patterns and implemented this approach to a physical control access.
A camera captures people walking and identifies the individuals using Steve’s approach.
After that, people must approximate their RFID badges. Both the identifications are required to open the door. In this case, we can say:
A red team operator wants to obtain credentials from a Windows machine without touching LSASS memory due to security controls and Credential Guard. They use SSPI to generate NetNTLM responses in the logged-in user context and collect those responses for offline cracking. Which attack technique is being used?
An experienced cyber attacker has created a fake Linkedin profile, successfully impersonating a high-ranking official from a well-established company, to execute a social engineering attack. The attacker then connected with other employees within the organization, receiving invitations to exclusive corporate events and gaining
