Using Deception to Enhance Security: A Taxonomy, Model, and Novel Uses -- The...

Mohammed Almeshekah

As the convergence between our physical and digital worlds continue at a rapid pace, securing our digital information is vital to our prosperity. Most current typical computer systems are unwittingly helpful to attackers through their predictable responses. In everyday security, deception plays a prominent role in our lives and digital security is no different. The use of deception has been a cornerstone technique in many successful computer breaches. Phishing, social engineering, and drive-by- downloads are some prime examples. The work in this dissertation is structured to enhance the security of computer systems by using means of deception and deceit. Deception-based security mechanisms focus on altering adversaries’ perception of computer systems in a way that can confuse them and waste their time and resources. These techniques exploit adversaries’ biases and present them with a plausible alternative to the truth bringing a number of unique advantages to computer security. In addition, deception has been widely used in many areas of computing for decades and security is no different. However, deception has only been used haphazardly in computer security. In this dissertation we present a framework where deception can be planned and integrated into computer defenses. We posit how the well-known Kerckhoffs’s principle has been misinterpreted to drive the security community away from deception-based mechanisms. We present two schemes that employ deception to protect users’ passwords during transmission and at rest when they are stored on a computer server. Moreover, we designed and built a centralized deceptive server that can be hooked to internet-facing servers giving them the ability to return deceptive responses. These three schemes are designed, implemented, and analyzed for their security and performance. The use of deception in security, and in computing in general, shows some fruitful results. This dissertation discusses some of the unique advantages of such mechanisms and presents a framework to show how they can be integrated into computer defenses. Also, it provides three practical schemes that employ deception in their design to address some existing security challenges. We postulate that the use of deception can effectively enhance the effectiveness of current security defenses and present novel ways to address many security challenges.

Planning and Integrating Deception into Computer Security Defenses

Mohammed Almeshekah

Deceptive techniques played a prominent role in many human conflicts throughout history. Digital conflicts are no different as the use of deception has found its way to computing since at least the 1980s. However, many computer defenses that uses deception were ad-hoc attempts to incorporate deceptive elements in them. In this paper, we present a model that can be used to plan and integrate deception in computer security defenses. We present an overview of why deception fundamentally works and what are the essential principles in using such techniques. We investigate the unique advantages deception-based mechanisms bring to traditional computer security defenses. Furthermore, we show how our model can be used to incorporate deception to many part of computer systems and discuss how we can use such techniques effectively. A successful deception should present plausible alternative(s) to the truth and these should be designed to exploit specific adversaries’ biases. We investigate these biases and discuss how can they be used by presenting a number of examples.

Excel Data Reporting: Assignment 3 Data Analysis (Feasibility Study Data Reporting) Assignment Checklist: ☐ Am I submitting my Excel workbook AND delivery of strategy (delivery can be a paper or a podcast)? ☐ Did I place all of my files into a folder and then compress that folder to upload to the FSO platform? ☐ Did I include messages in my chart titles to persuade my audience? ☐ Did I use projection formulas as well as percent change formulas to analyze the company's financials? ☐ Did I review the Worksheet Design Guidelines before submitting my Excel workbook? ☐ Did I use the correct chart types for my data? ☐ Did I properly format my axes so my audience will know how the data is being measured? (For example: dollar figures include dollar signs, percentages show the percent symbol) ☐ Do the Excel Data file and delivery form I'm presenting tell a persuasive story? ☐ Did I include citations and references for all of the sources I used for my data? Your introduction to the topic provides background information and prepares the reader for what follows. After discussing the OS vulnerabilities, you describe the threats to your environment. As you say, you can prevent weak password by setting up the security policies to enforce strong policies and this is so easy to implement that you can remove the threat right away. Instead of 'Week', try 'Weak'. You have very good material. The only item missed was the prioritization of the threats to decide which ones to mitigate. Good references and citations. Grade: 05/05 – Document Organization 15/15 – OS for Security 35/35 – OS Security Risks 34/35 – Mitigation Strategy 10/10 – Mechanics 99% Operating System Security Operating system security can be defined as the various sets of protection mechanisms or techniques employed by system administrators to prevent information theft and unauthorized resource access. All systems and especially in distributed systems require some measure of security that only allows authorized data manipulation and availability to employees of a company. Jinx will also need to secure its system to prevent both external and internal threats. Services that are mostly focus on in system security include; · Authentication: This is the validation of system servers or the identity of users or information/data senders within an organization. · Availability: Authorized users of a system should be able to access information freely in addition to withholding it from unauthorized access. This also includes shared resources in the system. · Authorization: This can also be referred to as Access Control. Organizations can limit the number of people access the network resources by simply verifying users when logging into the system. Using passwords and usernames is one way of controlling unauthorized access to computers and the system. However, authentication does not always guarantee a user full access to network resources or da ...

Running Head: 2 Week #8 MidTerm Assignment 1 The database is the most tender segment of the information technology (IT) infrastructure. The systems are susceptible to both internal and external attackers. Internal attackers are workers or individuals with the organization which uses data obtained from the organizational servers for personal gain. Organizations like Vestige Inc. holding nesh data for varying organizations require absolute security and sober database security assessment for effectiveness. The database security assessment is a process that scrutinizes system database security at a specific time or period (Ransome & Misra, 2018). Organizations offering data storage hold crucial information like financial data, customer records, and patient data. This type of information is of significant value to attackers and hackers highly target such information. It is thus crucial to perform regular system security assessments within the organization as the primary step to maximizing database security. Regular assessment eases bug identification offering promising results on the reliability of the systems. The current paper will highlight the significant process of carrying out database security assessments for the organization's system architect to ensure that it does not pose a danger to the parent organization database system. The database security assessment should consider using such techniques that do not exploit the system, which may result in system error or collapsing. As a primary assessment measure, the database architect considers susceptibility evaluation as the first action during the security assessment process. In this case, as adopted in the case of Vestige Inc., the security measurement occurs concerning known attackers. As a system architect, I will carry out an assessment based on knowledge of unsophisticated attackers. From this point, identification of areas across which vulnerabilities emanate from like weak or open database password policy and software coding error get identified and assessed vulnerabilities. Each component identified gets rated and reports on the different vulnerabilities generated and presented in infographics. The assessor will take the vulnerabilities and improve database security based on the obtained results. Architecture, threat, attack surface, and mitigation (ATASM) is a unique process that I will apply when assessing the security of the database systems. The procedure is essential for beginners as it keeps track of data within the system and follows a unique procedure to attain quality results and secure the systems (Schoenfield, 2015). With the model, the primary procedure will be understanding the logic and components of the system and highlighting communication flow together with vital data moved and stored in the database. The other adopted process on threats would be; listing possible threat agents and the goals of each threat model. Identify and formulate a ...
