MD5 Checksum Utility The goal of this paper is to define and explore the MD5 checksum utility. It is also my goal to discuss how to use MD5 checksums to support Incident Response. First off, I will start with talking a little about MD5 and where it stems from. In relation to cryptography, MD5 stands for Message Digest Algorithm 5. It is also known as RFC 1321. Cryptography is the basis for secure communications .It is by definition, a science of writing or reading coded message. MD5 falls

Data Encryption Shiqi Luo(701794770) The definition and importance of data encryption Data encryption refers to the process of transforming electronic information into a scrambled form that can only be read by someone who knows how to translate the code. In nowadays business world, it’s the easiest and most practical way to secure the information that we stored and processed, and it’s significant for our sensitive information. For example, as electronic commerce is popular now, the vendors and retailers

Technology is constantly changing, and as the capabilities change, so do the issues in Forensic information technology (FIT). FIT is defined as the scientific use or application of information technology (IT) that is used to generate and present digital evidence to be used in courts, legal or other formal proceedings (Volonio). While the use of technology helps get things done faster, it also can present many issues if the proper procedures and tools are not used and followed. An existing issue in
Application Level: An example of a highly important protocol which will be utilized at application level, is HTTP or hypertext transfer protocol. HTTP is the protocol used within web browsers and the entire internet to send and receive specific web page data. HTTP is a controlling protocol, as it determines how documents should be sent, and what the browser should do in response to commands. When accessing a web page, a HTTP command is sent to the pages web server, so that the server may send that
User Datagram Protocol is one of the transport layer protocol which offers limited amount of service when messages are exchanged between hosts. Data is further subdivided into data grams for transmission across the hosts. UDP does not allow retransmission of the damaged or lost packets and there is no acknowledgement for the packet which has been sent. DGRAM_SOCK is the type of socket used for transmission of data. Unlike TCP, however, UDP does not provide the service of dividing a message into packets
Introduction In the OSI model of computer networking, the data link layer is layer two of seven and corresponds to the host-to-network layer of the TCP/IP reference model. Its main aim is to reliably transfer data between two adjacent machines whilst efficiently detecting and correcting errors in transmission. Packets from the network layer are packed into frames and transferred to the network layer on another machine. Data link layer protocols respond to the network layer and issue requests to
Computer Viruses and their Effects on the Computer In our health-conscious society, viruses of any type are an enemy. Computer viruses are especially pernicious. They can and do strike any unprotected computer system, with results that range from merely annoying to the disastrous, time-consuming and expensive loss of software and data. And with corporations increasingly using computers for enterprise-wide, business-critical computing, the costs of virus-induced down-time are growing along with
The Power On Self Test When the system is powered on, the BIOS will perform diagnostics and initialize system components, including the video system. (This is self-evident when the screen first flicks before the Video Card header is displayed). This is commonly referred as POST (Power-On Self Test). Afterwards, the computer will proceed its final boot-up stage by calling the operating system. Just before that, the user may interrupt to have access to SETUP. To allow the user to alter the CMOS
having 64KB blocks. A chunk is identified by its handle called the chunk handle and each chunk is replicated thrice by default. Each block in a chunk consists of a 32-bit checksum. The HDFS file content is divided into 128MB blocks. A node called the namenode holds the blocks replica as two files, one for data and another for checksum and stamp generation. In GFS client accepts the request for a read operation and sends the request to the master, the master then generates a chunk handle and replica
In addition, some means must be in place to detect any changes in data that might occur as a result of non-human-caused events such as an electromagnetic pulse (EMP) or server crash. Some data might include checksums, even cryptographic checksums, for verification of integrity. Backups or redundancies must be available to restore the affected data to its correct state. For example, if you were sending an online money transfer for $100, but the information was tampered in such
According to [3], game design refers to “something to program about.” When creating games, one must take into account the flow and structure of a game. These cannot be ignored since a domino effect follows: poor design will lead to a poor implementation of the game. A poorly implemented design would then lead to a program that is vulnerable to both simple and complex attacks. [1] mentions that loopholes or bugs in games may occur as a product of poor game design. This brings another point: poor design

Discuss the current health status comparisons between Indigenous and non-Indigenous Australians and interventions to remedy these inequalities.” Charmine A Hines 25171720 Aboriginal and Torres Strait Islanders have some of the worst health outcomes in comparison to any other indigenous community in the world

Networking is another way that advances in computer engineering and software has paved a way for the advancement of communication, industry, and our lives in general through technological advancements. Just as the utilization of fire and carving of the wheel gave us advantages over the perils of life, the networking of computers has brought an unreachable far off world closer to each and every one of us. First and foremost we are now able to nearly instantaneously share information with an unreachable
Cryptography Cryptography is the science of using mathematics to encrypt and decrypt data. Cryptography enables you to store sensitive information or transmit it across insecure networks so that it cannot be read by anyone except the intended recipient. While cryptography is the science of securing data, cryptanalysis is the science of analyzing and breaking secure communication. Classical cryptanalysis involves an interesting combination of analytical reasoning, application of mathematical tools
Most small to mid-size corporations cannot afford a complete Computer Emergency Response Team (CERT). A lot of large outsource this operation as well. The team being internal or external makes a significant difference in the first stages of an investigation. We will assume that we are working as a forensic contractor. Given the most opportune situation our forensic team should consist of multiple job titles, but some of these may be held by the same person. One very important position is a legal
The WPS protocol relies on an eight digit Personal Identification Number (PIN) to allow the authentication of users on to the network. The protocol further relies on a session of eight Extensible Authentication Protocol (EAP) messages that are followed by a final message which identifies the successful completion of the session. WPS automatically configures the network name (SSID) and the WPA security key for the access point and the WPS enabled client. The benefit is that a user does not need to
COS0013-LAB TEST 1 1. What is a “honeypot”? It is a trap set in computer system is used to detect unauthorized access and to collect information regarding intruder or attacker in the system. Honeypot is considered as one of the security technique used in the computer to trap the attacker. 2. What is “blackholling”? Blackholling is used to stop the denial of attacks and malware based attacks. It is a technique used by the internet service providers to block the data coming from certain ip addresses
