...“Reverse engineering is the process of extracting the knowledge or design blueprints from anything man-made. Reverse engineering is usually conducted to obtain missing knowledge, ideas, and design philosophy when such information is unavailable. In some cases, the information is owned by someone who isn't willing to share them. In other cases, the information has been lost or destroyed” (Eilam, 2005). The advantages and disadvantages of reverse engineering are as follows; Advantages * It helps in the evolving of existing computing systems. * “You can change a program's structure and thus directly affect its logical flow. Technically this activity is called patching, because it involves placing new code patches (in a seamless manner) over the original code” (Hoglund & McGraw, 2004). * As a learning tool * As a way to make new compatible products that are cheaper than what's currently on the market. (Schwartz, 2001) * For making software interoperate more effectively or to bridge different operating systems or databases. * To uncover the uncoordinated features of commercial products. Disadvantages * “Manually translated source code often retains the style and flavour of the original implementation”. (Byrne, 1991) * “The most commonly recognized problem with literal translation is summed up as: garbage in, garbage out. If the existing system is not well-structured, both in terms of its architecture and control-flow, then the resulting system will be of the same...

...Cloud computing: benefits, risks and recommendations for information security Cloud computing is a new way of delivering computing resources, not a new technology. Computing services ranging from data storage and processing to software, such as email handling, are now available instantly, commitment-free and on-demand. Since we are in a time of belt-tightening, this new economic model for computing has found fertile ground and is seeing massive global investment. According to IDC’s analysis, the worldwide forecast for cloud services in 2009 will be in the order of $17.4bn1. The estimation for 2013 amounts to $44.2bn, with the European market ranging from €971m in 2008 to €6,005m in 2013 2. The key conclusion of ENISA’s 2009 paper on Cloud Computing: benefits, risks and recommendations for information security3 is that the cloud’s economies of scale and flexibility are both a friend and a foe from a security point of view. The massive concentrations of resources and data present a more attractive target to attackers, but cloud-based defences can be more robust, scalable and cost-effective. ENISA’s paper allows an informed assessment of the security risks and benefits of using cloud computing - providing security guidance for potential and existing users of cloud computing. The new economic model has also driven technical change in terms of: Scale: commoditisation and the drive towards economic efficiency have led to massive concentrations of the hardware resources required to provide...

Forensics is the process of using scientific knowledge for collecting, analyzing, and presenting evidence to the courts. (The word forensics means “to bring to the court.”) Forensics deals primarily with the recovery and analysis of latent evidence. Latent evidence can take many forms, from fingerprints left on a window to DNA evidence recovered from blood stains to the files on a hard drive. Because computer forensics is a new discipline, there is little standardization and consistency across the courts and industry. As a result, it is not yet recognized as a formal “scientific” discipline.

...Cyber Security by American Military University Professor Derrick Thomas June 22, 2014 Cyber security is a difficulty that everyone faces in today’s society. It is defined in a variety of ways by many. One definition is that cyber security focuses on protecting computer networks, systems, data, and programs from unwanted access. Cyber security is sometimes referred to as information security, information network security, cyberspace security, or even computer security. There are many viewpoints by highly educated people on cyber security but the purpose of this paper is to tell my viewpoint on the subject. Every aspect of a persons life has some sort of cyber dimension. People paying for bills online, cloud computing, and even online gaming. This year in 2014, everyone is bombarded with news headlines that say cyber threats are up. Many of these headlines always include some kind of phishing attack trying to steal someones identity, a hacker that breached the network of a company, a new technique that attacks mobile devices like smart phones, or a government trying to monitor and take secrets from another government!!br0ken!! The concern for cyber security is now a real-world concern globally. The concern over cyber security is what is driving the governments worldwide to make it priority one on their list's now. This is so, because technology is growing at a very fast and continuous pace. The technology field itself is very vast and has much variety. Cyber security...

...Abstract: Advanced cyberattacks on the public and private sectors at the local, national, and international level have prompted an increase in funding and support for the study of emerging cybersecurity technologies. The considerations for this paper are to discuss the emerging technologies and strategies that can be integrated across the public and private sector to improve cybersecurity on a local, national, and international level. New technologies need to dynamically assess networks real-time such as with the use of Remote Agents and Real-time forensic analysis. These technologies also need to make the attack space less predictable and constantly evolving such as through the use of moving target defense. Emerging Cybersecurity Technologies The E-government Act of 2000 was signed by President Bush to move toward a more 24-7 government. The dream was to eliminate the need to have to stand in line at the DMV for half a day just to pay annual vehicle registration fees (Barker, 2011). Security was certainly a concern, but it was not at the forefront of the move as government agencies would go through massive changes in equipment, manning, and practices in order to move information and programs online. Now, over a decade later we still see moves and changes taking place, such as the department of Veterans Affairs recently moving all of their applications, forms and records online. The expensive cost of getting the government caught up was expected with such an overhaul...

...Unit-4 (ICS -305) Information security Information security (ISec) describes activities that relate to the protection of information and information infrastructure assets against the risks of loss, misuse, disclosure or damage. Standards that are available to assist organizations implement the appropriate programs and controls to mitigate these risks are for example BS7799/ISO 17799, Information Technology Infrastructure Library and COBIT. Information security management (ISM) describes controls that an organization needs to implement to ensure that it is sensibly managing these risks. Security Challenges The risks to these assets can be calculated by analysis of the following issues: Threats to your assets. These are unwanted events that could cause the intentional or accidental loss, damage or misuse of the assets Vulnerabilities. How vulnerable (prone or weak) your assets are to attack Impact. The magnitude of the potential loss or the seriousness of the event.

Since electronic evidence is fragile and can easily be modified, finding this data, collecting, preserving, and presenting it properly in a court of law is the real challenge. There is a need for use of semantic analysis to discover underlying security policy requirements and internal power structures and institutionalization of anti cyber attack, antimoney-laundering and regulatory schemes. The first responders to cyber security incidents often than always are an organization ICT personnel who are technically sound though may be deficient in investigative skill.

...Digital Forensics: Uganda’s Preparedness Dennis Tusiime Rwatooro 2014-M142-2002 Dept of Computer Science Abstract — The more our lives continue to depend on digital communication networks and media to perform daily activities such as communication, access to information and critical services such as health, financial transactions, entertainment, and public utilities like electricity, the more we get exposed to security risks. These security risks include breach of confidentiality of communication and transactions, violation of personal privacy, crime and fraud, disruption of services, and distribution of inappropriate content, among others. The goal of digital security is to research into and develop mechanisms to address these security risks. In this paper we briefly survey some of the emerging issues in digital security. The literature shows that while some domains in digital security have remained unchanged over a long time, for example cryptography, new areas have emerged including steganography. Keywords – digital forensic techniques, volatitle data extraction, digital image forensics, malware investigations, email security, symmetric key cryptography, asymmetric key cryptography, public key cryptography. Introduction Forensic science is defined as the application of the sciences as it pertains to legal matters or problems (Gialamas, 2000). One of the branches/fields of forensic science, namely criminalistics, is the profession and scientific discipline oriented...

...Computer Intrusion Forensics Research Paper Nathan Balon Ronald Stovall Thomas Scaria CIS 544 Abstract The need for computer intrusion forensics arises from the alarming increase in the number of computer crimes that are committed annually. After a computer system has been breached and an intrusion has been detected, there is a need for a computer forensics investigation to follow. Computer forensics is used to bring to justice, those responsible for conducting attacks on computer systems throughout the world. Because of this the law must be follow precisely when conducting a forensics investigation. It is not enough to simple know an attacker is responsible for the crime, the forensics investigation must be carried out in a precise manner that will produce evidence that is amicable in a court room. For computer intrusion forensics many methodologies have been designed to be used when conducting an investigation. A computer forensics investigator also needs certain skills to conduct the investigation. Along with this, the computer forensics investigator must be equipped with an array of software tools. With the birth of the Internet and networks, the computer intrusion has never been as significant as it is now. There are different preventive measures available, such as access control and authentication, to attempt to prevent intruders. Intrusion detection systems (IDS) are developed to detect an intrusion as it occurs, and to execute countermeasures when detected...
