Hartbleed attack. This sample question is to check if you could do the hartbleed attack.If you’re able to do that I’ll create a question with the price that you ask. Thank you.
Overview
The Heartbleed bug (CVE-2014-0160) is a severe implementation flaw in the OpenSSL library, which enables attackers to steal data from the memory of the victim server. The contents of the stolen data depend on what is there in the memory of the server. It could potentially contain private keys, TLS session keys, usernames, passwords, credit cards, etc. The vulnerability is in the implementation of the Heartbeat protocol, which is used by SSL/TLS to keep the connection alive. The objective of this lab is for students to understand how serious this vulnerability is, how the attack works, and how to fix the problem. The affected OpenSSL version range is from 1.0.1 to 1.0.1f. The version in the SEEDUbuntu 12.04 VM is 1.0.1.
Part 1
You need to submit a detailed lab report, with screenshots, to describe what you have done and what you have observed. You also need to provide explanation to the observations that are interesting or surprising. Please also list the important code snippets followed by explanation. Simply attaching code or screen shots without any explanation will not receive credits. Make sure you explain all your work even the sudo and Unix commands. Make sure you have detailed understandable explanation.
You can download the lab file from:
Part 2
Answer the following questions based on your assignment 5 submission and understanding and relate your answers:
1.What is the purpose of the Heartbeat protocol based on your part 1 report?
2.Describe what the mistake is in the Heartbleed vulnerability.
3.What lesson do you learn from this vulnerability?
4.The figure shows where a malicious Heartbeat request packet is stored in the memory after it is received. The payload length field contains 0x700. Please in detailed explanation describe which credit card numbers will be stolen by the attacker.
5.Assume that the Heartbeat implementation uses the actual payload length when allocating memory for the response packet (i.e., the memory for the response packet will the same size as that for the request packet). However, during the memory copy, the claimed payload length is used. What kind of security problems does it have?
Important Note: You need to show the full screenshot of the terminal window with detailed explanation of code and commands failing to do so you will not be graded and lose 75% of the grade.

You must submit two separate copies (one Word file and one PDF file) using the Assignment Template on Blackboard via the allocated folder. These files must not be in compressed format.
It is your responsibility to check and make sure that you have uploaded both the correct files.
Zero mark will be given if you try to bypass the SafeAssign (e.g. misspell words, remove spaces between words, hide characters, use different character sets, convert text into image or languages other than English or any kind of manipulation).
Email submission will not be accepted.
You are advised to make your work clear and well-presented. This includes filling your information on the cover page.
You must use this template, failing which will result in zero mark.
You MUST show all your work, and text must not be converted into an image, unless specified otherwise by the question.
Late submission will result in ZERO mark.
The work should be your own, copying from students or other resources will result in ZERO mark.
Use Times New Roman font for all your answers.

Becoming a Technical Support Professional
Welcome to becoming a technical support professional! After watching this video, you will be able to define technical support, discuss the importance of technical support, and list reasons for choosing technical support as a career.
Technical support is a good profession for people who like problem-solving and enjoy helping to resolve technology issues. It allows companies to provide helpful solutions to their customers. When companies provide support to their customers, they are viewed more positively and can see an increase in business. Technical support also helps companies to track and troubleshoot their technology, which can lead to product improvement and help companies develop more desirable products.
A career in technical support can help you learn more about technology, develop your professional skills and open the door to many other opportunities and paths in technology-related careers. In this video, you learned that technical support is working with clients and customers to solve technology-related issues. Different kinds of companies from large to small use technical support to assist their customers, and use technology like phones, email, live chat, social media and online community forums to do so. Technical support also allows companies to log and track problems and the actions taken to resolve them.
Skills Needed for Technical Support
To get started in technical support, you need to have a natural curiosity for how things work. It’s a great career choice, whether you have any prior degree or IT experience in the field. Essentially, you require two sets of skills: information technology skills, as well as customer support skills. Employers prefer applicants to have IT-related qualifications. However, a technical support executive must do certifications in the domain they are in.
You can develop these skills by taking courses, getting certifications, completing diplomas, and gaining experience.
CompTIA is an excellent starting point to learn about information technology skills. You can learn about the basics via the web or books. It’s a great way to understand the basics of learning.

Task 6 – Week One Discussion – IPv6 Duplicate Address Detection
Task 6 – Week One Discussion – IPv6 Duplicate Address DetectionHosts on a network use Duplicate Address Detection (DAD) to ensure that no other hosts have the same IPv6 address on the network. This happens no matter how the host received it’s IPv6 address whether it was statically, through DHCPv6 or through SLAAC. In no less than 350 words, describe the process a PC takes to perform a DAD check on the network. Be sure to understand this process as it is a key topic for the CCNA exam.
