Spoofing attack

1. How can ARP spoofing attack be controlled permanently? What are the drawbacks of S-ARP protocol, Static MAC Entries, Kernel based patches? Answer: 1.1.1 Secure ARP Protocol (S-ARP) This has been proposed as a replacement for the ARP protocol in [10]. The S-ARP protocol is definitely a permanent solution to ARP spoofing but the biggest drawback is that we will have to make changes to the network stack of all the hosts. This is not very scalable as going for a stack upgrade across all available

and pocketing the different into the employee’s own paycheck. A lack of encryption controls and authentication, were determined by the IT department, to be what allowed the employee to hack into the HR system. 2. Notification Different types of attacks required different processes and procedures. Due to

hackers, virus attacks, misuse and prevents unauthorized access. The importance of learning and becoming aware of network security is important for protecting yourself and others around you. I will be discussing the common type of attacks, methods to protect your computer from harm and discuss what the future may hold for network security. There are many attacks that can be associated with network security, eavesdropping, viruses/malware and Trojans, phishing, IP spoofing attack and lastly denial

incident. One of the areas that were not identified was how the network system allowed the spoofing and was not caught much earlier. Were permissions already in place? Do they have a network logging system that analyzes the logs? The lack of other system checks were not addressed in this scenario. 2.  Outline the other attacks mentioned in the scenario that were not noticed by the organization. An attack that was not mentioned in the scenario was social engineering. The employee that manipulated

group dedicated to AOL including warning on all its email and messaging software to send alert to the users regarding potential phishing abuse.

We decided to prank call a family

employee was able to hack into the computer system and gain access to the financial payroll system, human resources and even email system. This employee used several methods in order to gain access into the system: IP spoofing, Data modification, Man in the middle attack and compromised-key attack. As a result the employee was able to tamper with payroll system. An auditor discovered the discrepancies and tried to make upper management aware of the situation through email, but the email was intercepted

Account hijacking - again, this attack’s severity is high because the attacker had access to finance record accounts on the finance information systems. Email spoofing attack - email spoofing is a medium severity attack because it is an easily mitigated attack; it is mostly a nuisance to most organizations. MITM attack - the severity of an MITM attack is medium since the attacker used it to intercept messages between the auditor and the finance department; it can be easily mitigated with network and VLAN

Perform a post event evaluation of how the organization’s IT staff responded to the attack described in the scenario by doing the following: A1. Describe the nature of the incident. An employee succeeded in unauthorized access to human resource record system and modified financial record that changed the employee’s base salary rate to obtain a raise. The inconsistency was detected by the auditor, after two paychecks has been processed and paid to the employee. The auditor notified some individuals
