An administrator has been working within an organization for over 10 years. He has moved between different IT divisions within t
he company and has retained privileges from each of the jobs that he's had during his tenure. Recently, supervisors admonished him for making unauthorized changes to systems. He once again made an unauthorized change that resulted in an unexpected outage and management decided to terminate his employment at the company. He came back to work the following day to clean out his desk and belongings, and during this time he installed a malicious script that was scheduled to run as a logic bomb on the first day of the following month. The script will change administrator passwords, delete files, and shut down over 100 servers in the datacenter. What could have discovered problems with this user's account while he was employed
User permissions and access control. Explanation: The question describes a situation where a former employee returned to the office and installed malicious software on a computer that was set to execute a logic bomb on the first day of the next month. This script is designed to alter administrator passwords, erase files, and shut down over 100 servers within the data center. Issues related to that account might include unauthorized access by users who have permissions to system resources. If such individuals gain unauthorized access, they could easily alter or damage the system's operations. Additionally, the firewall may need to be disabled to recognize the harmful script, highlighting the necessity of keeping firewalls operational to prevent attacks from unauthorized users. Furthermore, if user roles are not clearly defined, it increases the risk of unauthorized modifications to the system, potentially leading to unforeseen outages.
a. Current disks do not reveal the actual locations of logical blocks.
Clarification:
Modern disks incorporate scheduling algorithms within the disk drive itself. This presents challenges for operating systems trying to optimize rotational latency. All scheduling methods end up having to perform similarly due to potential constraints faced by the operating system. Disks are typically accessed in physical blocks. Modern technology applies more electronic control to the disk.

The type of session hijacking attack that Sean is illustrating is Blind Hijacking, option C.
Explanation:
This is because he is inserting harmful data or commands into the compromised communications within the TCP session, regardless of the source-routing being turned off. He is capable of sending the data or commands, but does not have the ability to view the responses.
EMI, or Electromagnetic Interference, can also be referred to as Radio-frequency Interference (RFI) within the radio frequency domain.
An unshielded ethernet cable, made from copper, might function as an antenna; any external noise that interferes with it can corrupt the data signal, resulting in data integrity issues and distorted signals.
