General Purpose Computing And Communications Systems

As we can see, large number people usually come online to use this digital innovation in order to quickly perform their required tasks, it is very important for users of every single level or sophistication which also includes users sitting at home, small and medium range businesses, non-profitable or profitable organizations, education institutions and even large enterprises should have sufficient knowledge related to that cost-effective equipment that could let them stay safe either personally and professionally from cybercrimes. The

Cyber-security demands are ever increasing in the field of Information Technology with the globalization of the internet. Disruptions due to cyber-attacks are affecting the economy, costing companies billions of dollars each year in lost revenue. To counter this problem

Moreover, it is important to note that while cryptography is necessary for secure communications, this report is not by itself sufficient. The reader is advice then, that the topics covered in this paper only describe the first of the many steps necessary for better security in a number of situations.

Security at hardware level is a new trend in security industry; it will accelerate the security at the processor and chip-set level (Vaquero, Rodero-Merino and Moran, 2011:112). Antivirus solution with Computers and Hardware will eliminate antivirus and Firewall security solutions industry. (Bruce Schneier accessed January/9 2013). Intel is planning to move computer security to the hardware level from its current software level, by incorporating security features onto their chips and processors (MEED 2010).This will also hit the IT Security devices market.

The Security architecture logically separates complicated arrangement of end to end system’s security related features into discrete architectural components. This discretion allows a certain systematic way to deal with end to end security that can be utilized for planning of new security solutions and for accessing the security of the current networks. The security architecture gives a complete, top-down, end-to-end point of view of system security and can be connected to network components, administrations, and applications keeping in mind the end goal to distinguish, anticipate, and correct security vulnerabilities.

Since the birth of the computer and the internet we have witnessed almost every business worldwide discard the timely usage of paper documents and filing systems and welcome the use of database servers which has enabled greater productivity, accuracy and availability. Many businesses like banks obtain highly sensitive personal information from their clients which is stored on database servers and encrypted with the goal of protecting their data from unauthorized users. Data being stored on servers creates an illusion of safety with them often being operated from a different geographic location, criminals can no longer physically take this data from a business’s premises as it is not stored locally, although cyber criminals have evolved along with these times and have proven time and time again that data security measures are still very exploitable across networks. The emerging digital age we now live in has become an extremely vulnerable and volatile environment and with networks becoming increasingly vast, it has become apparent with hackers constantly exploiting security measures that our data is never 100% safe. In 2005 a 24 year old Cuban-American by the name of Albert Gonzalez masterminded an attack which saw “over 150 million credit card and ATM numbers between 2005 and 2007” (Ottman, 2011) stolen and subsequently sold on the black market which has been labelled the biggest such fraud in history. Although millions of dollars are spent trying to catch cyber criminals

Generally, computer network security systems and structures considered robust are preceded not by software and hardware but by careful planning. A typical computer network security plan must take into consideration a wide range of security risks and vulnerabilities and from that, develop a road map to reduce such exposure. Given the need to protect the integrity and confidentiality of data as well as other system quality attributes, the need to mitigate exposure cannot be overstated.

Security incorporates a few subsets like checking, border and physical. Likewise, they add to the inclining design in any association. Furthermore, innovation in the space for the system security has gone through a few ways and paths. In addition, new working frameworks of

Hardware is the basis of any computing system and, as such, should be the first part of the system to consider security. The research presented in Trustworthy Hardware from Untrusted Components looks at the present state of hardware security, analyzes the vulnerabilities and possible solutions, and presents an alternative approach to ensure that the end-result of the hardware design process is a secure and trustworthy piece of hardware.

Abstract—Embedded systems being designed are highly reliable, respond well to the real time systems, provide flexible functionality and able to work given low power sources. These various systems currently find their applications in the areas which involve managing very extensive data including location determination, health, bank details and personal information which makes security a vital factor of the embedded system domain. In this paper, the security algorithms involving cryptography has been focused in the area of networks and basic processors. We study the two main classification of cryptographic algorithms namely symmetric-key and public-key ciphers, used to protect communication networks by utilizing the different security protocols as well as protecting data of the computer systems. Symmetric-key ciphers and public key ciphers find their applications in fields governing data encryption, authentication and digital signatures. Further becoming an essential part of the embedded systems involving programmable network devices as there is a rise in the connectivity of the networks which increases the role of cryptography algorithms from servers to sensors and smartcards. We study the implementation of encryption algorithms on System on Chip dual core ARM model. However, majority of

In addition to this, the topic named security issues and vulnerabilities of smartcards is proposed for carrying out this research study as there is an increased popularity of the smartcards in different business organizations due to which attackers poses harm to the security aspects of the applications that are supported by the smartcard technology as it is used for providing security to such applications for the purpose of carrying out different activities smoothly and efficiently. In this context, the following research study concentrates on the security threats and vulnerabilities associated with smartcards and measures to be taken to reduce and eliminate it in order to improve the efficiency and usage of smartcard technology by different business organizations for carrying out different transactions in a secured manner (Pappu, Carvalho and Pardalos

A specialized field in computer system security that involves securing a computer system hardware and software. Security is typically handled by a system administrator who implements the security policy, network software and hardware needed to protect a system and the resources accessed through the network from unauthorized access and also ensure that employees have adequate access to resources. A system security typically relies on layers of protection and also consist of multiple components includes networking monitoring and security software. All components work together to increase the overall security of computer system. Passwords are extremely effective system for improving system security if applied properly. Security is the fundamental component of every system design. When planning, building and operating a system we should understand the importance of a strong security policy. The easier way to protect a network into the computer system from an outside attack is to close it

An end to approach and firm grasp of vulnerabilities are useful in order to secure the modern business infrastructure and IT infrastructure demands. While this kind of knowledge cannot prevent all attempts at system attack or network attack, which can empower network engineers to eliminate general problems, highly reduced potential damages and detects breaches very quickly. With the rise in increasing number and complexity of attacks, vigilant approaches to security in both large and small enterprises are a must. These days even a small sized business organizations as well as medium sized organizations have lot of money due to repeated fraudulent transactions. These are mainly due to the fraudulent electronic financial

The present decade has experienced a rapid growth in the production of electronic devices. These devices have surely increased the accessibility and comfort but they are also subject to security issues. The increase in security of such electronic facility has been a necessity with the introduction of hardware circuits which tamper their behavior. “A Hardware Trojan is a malicious, undesired, intentional modification of an electronic circuit or design, resulting in the undesired behaviour of an electronic device when in operation. It is like a back-door that can be inserted into hardware – a foothold that an adversary can leverage to attack a system” [1]. A hardware Trojan is considered to be an intentional modification in the physical structure of the IC which can render the IC to be either functionless or malfunction. Such conditions can result in disastrous outcomes when it comes to applications of high level security and military usage. A hardware Trojan can either use the existing signals in an IC and corrupt or alter them, hence damaging the data and commands and in turn resulting in improper execution of the hardware. It can also

E-commerce Security is protecting assets of e-commerce from any unauthorized access, modification or deletion. E-commerce Security should follow the basic CIA model i.e. confidentiality, integrity, availability of Information Security. With the growing demand of E-commerce in the market, exploitation of its security is also subjected to increase, thus increasing the potential for white collar crimes. Internet Banking is a flexible and easy mode of online payment provided by banking sectors to e-commerce but as every coin has two faces, the benefits come with some hidden flaws. The possibility of fraud is seen as the major reason why today’s companies are spending billions of dollars on computer security. In this paper we discuss overview
