Internet Protocol Security

IPsec is the short abbreviation for Internet Protocol Security which is referred to as the protocol suite used in securing the Internet Protocol (IP) network communications through encrypting and validating each IP packet (data sent over the internet) of a communication session. Internet Protocol security comprises procedures and protocols used in establishing a reciprocated authentication or verification procedure between artificially intelligent agents at the commencement of the interconnection period and the intercession of cryptographic keys to be used by the network user during the given time lease period (Black, 2000).
Internet Protocol security can be used in guarding data and ...

Abstract— This paper tries to explain the concept of hash tags and how the trending hash tags are determined by Twitter. To explain the working we have tried to analyze and algorithm from a source and on the basis of that we are trying to understand the steps taken in computing the trending topics on twitter. We are also presenting with some methods for users to find the trending topics on twitter.

It’s the age of Internet. Twitter is the new singing birdie. Twitter allows us to know not only what’s hot in our area but ...

In 1991, The National Institute of Standards and Technology (NIST) developed Digital Signature Algorithm (DSA) and it was put forward for use in Digital Signature Standards (DSS). It is actually a Federal Information Processing Standard used in digital signatures. It was accepted as FPIS in 1993 and since then it has undergone several improvements with the latest FPIS 186-4 was done in 2013. DSA is used to create a 320 bit signature that contains 512-1024 bit security. Digital Algorithm Signature is advantageous over RSA since it faster and smaller as compared to RSA. It was approved by the government of United ...

Introduction:

As information technologies evolved and became more important for business and home use, users demanded for ways of directly connecting to systems in different locations. From large internet service providers, operators of bulletin board systems, to businesses getting critical data to road warriors in a timely manner, remote system access and networks became critical services that administrators were required to provide. However, it was necessary to ensure that only authorized users could access the provider’s resources, they could only access the resources they needed, and the administrators could track the users’ activities and access time for purposes of ensuring ...

In the present era influenced by ideological and social revolutions, the rapid growth of technology has enabled social media to interconnect the minds of individuals with no need of their physical presence. This kind of innovative communication method is gradually changing the way we interact with others thus nurturing a new form of community called virtual community. Currently, Sina Weibo is an extremely popular social media website in China. By the third quarter of 2015, this micro-blogging site had 222 million registered users and 100 million daily active users. Sina Weibo gathers a lot of posted ...

Abstract

The use of encryption and decryption techniques for securing communication is as old as the art of communication. Technically, a code is used instead of data which is a signal for intent to keep data secret. In order to recover the contents from an encrypted signal, accurate decryption key is needed. The key is basically an algorithm that is used to reverse the work of the encryption technique and get original form of data. There is always a potential threat from hackers to decode encrypted signal, to avoid such issues specialized intellectuals have worked hard and defended these threats by developing more ...

Thesis: Social media is increasingly becoming a fundamental tool for fostering political awareness and action in Saudi Arabia.

Introduction
Saudi Arabia has one of the most repressive media regulations in the world with a score of 83/100 in the most recent survey by the Freedom House, where 0 represents the best score while 100 represents the worst score. The authorities mugged the freedom of the media, further, in 2014 with the passage of the antiterrorism legislation and a series of arrests that silenced some of the most vocal critics (Freedom House). The fragile environment from which journalist operate from has led to a high level of suspicion on the mainstream media which is controlled by powerful government ...

The information at hand does not conclusively determine if a crime has been committed or not. It is thus important to secure the scene of crime.
The plan for include developing the infrastructure to determine if an attack really happened and what are the extent. This will ascertain the validity of claims of breach and if confirmed take appropriate steps to retrieve reliable digital evidence that can be used sufficiently to sustain a case at the court of law. Before the start of digital investigation, time on all the servers was synchronized with NTP.
Verification of suspected crime will ...

- Introduction
Over the centuries, there has been the need to transmit secret information between a sender and a receiver. So many techniques have been developed and used in order to achieve this aim. One popular technique is cryptography; an art that encodes information as a cipher and can only be accessed by the sender or a receiver that knows the decryption code. The mere sight of coded information raises a lot of curiosity and suspicion. Anybody interested in such information may then commence efforts at deciphering the code. In order to eliminate this development, there was the need to transmit covert information ...

When scientific methods are used in the process of preserving, collecting, validation, identification, analysis, interpretation, documentation, and presentation of digital evidence from digital sources, then the process is called digital investigation. The evidence may be used to facilitate the construction of events deemed to be criminal or are in contrast with the laid down procedures.
Digital investigations for an organization differ to digital investigation for law enforcement because of the procedure adopted. Different models of operation have been suggested depending on the complexity of the situation.
Digital investigations arise as a result of an occurrence suspected, attempted or ...

Plan for Processing a Potential Crime Scene

Identifying the Potential Digital Evidence
Processing a crime scene will involve following standard procedures used in assessing a digital crime scene. According to Wile and Reyes (2011), the process of identifying the potential digital evidence will require a series of investigations to be done. Thus, this will involve assessment of the case, asking the affected parties questions, locating the evidence and documenting the results with the goal of identifying where the crime was exactly committed. In this case, the first clue to potential evidence will be to assess the intrusion detection logs. Additionally, it is important to note that network intrusions ...
