Steganography As a Means of Attacking Information Systems
Scientific and Practical Cyber Security Journal (SPCSJ) 2(4): 75-80 ISSN 2587-4667 Scientific Cyber Security Association (SCSA) STEGANOGRAPHY AS A MEANS OF ATTACKING INFORMATION SYSTEMS Anna Romanova 1, Sergiy Toliupa 2 1Taras Shevchenko University of Kyiv, Faculty of Information Technology, 2 Taras Shevchenko University of Kyiv, Faculty of Information Technology ABSTRACT. An analysis of steganography methods that are can be potentially used as instruments in attacks on information and communication systems is presented. The possible solutions to ensure resilience to such attacks are presented. Keywords: steganography, TEMPEST, covert channel, information protection Cryptography is widely used as one of the most efficient and approbated methods of critical information resources protection. Nevertheless, in particular cases it might be more effective to hide the communication channel itself instead of making the information within it unreadable. Such a practice, namely concealing data within unsuspicious, innocent-looking containers, is called steganography. Any concept might have a double application. While being primarily considered a means of information protection, steganography can be used with ill intentions, as well. In fact, several high-tech attacks are based on the hidden data transmission, and contemporary methods of counteraction do not provide satisfactory level of resilience to those. These attacks are not always considered to be steganography-based, as they, for the most part, use a variety of features, characteristic for information and communication systems – physical effects, transmission protocols, communication infrastructure, specific features of software, cryptography etc. Nevertheless, the attack requires a classical statement of the task of steganography – how to transmit data so that a potential attacker could not acquire them due to not knowing about the presence of a transmission channel, even if he or she has a suspicion about one and the possible methods are known. -
Threat Defense: Cyber Deception Approach and Education for Resilience in Hybrid Threats Model
S S symmetry Article Threat Defense: Cyber Deception Approach and Education for Resilience in Hybrid Threats Model William Steingartner 1,* , Darko Galinec 2 and Andrija Kozina 3 1 Faculty of Electrical Engineering and Informatics, Technical University of Košice, Letná 9, 042 00 Košice, Slovakia 2 Department of Informatics and Computing, Zagreb University of Applied Sciences, Vrbik 8, 10000 Zagreb, Croatia; [email protected] 3 Dr. Franjo Tudman¯ Croatian Defence Academy, 256b Ilica Street, 10000 Zagreb, Croatia; [email protected] * Correspondence: [email protected] Abstract: This paper aims to explore the cyber-deception-based approach and to design a novel conceptual model of hybrid threats that includes deception methods. Security programs primarily focus on prevention-based strategies aimed at stopping attackers from getting into the network. These programs attempt to use hardened perimeters and endpoint defenses by recognizing and blocking malicious activities to detect and stop attackers before they can get in. Most organizations implement such a strategy by fortifying their networks with defense-in-depth through layered prevention controls. Detection controls are usually placed to augment prevention at the perimeter, and not as consistently deployed for in-network threat detection. This architecture leaves detection gaps that are difficult to fill with existing security controls not specifically designed for that role. Rather than using prevention alone, a strategy that attackers have consistently succeeded against, defenders Citation: Steingartner, W.; are adopting a more balanced strategy that includes detection and response. Most organizations Galinec, D.; Kozina, A. Threat Defense: Cyber Deception Approach deploy an intrusion detection system (IDS) or next-generation firewall that picks up known attacks and Education for Resilience in or attempts to pattern match for identification. -
NSA's Efforts to Secure Private-Sector Telecommunications Infrastructure
Under the Radar: NSA’s Efforts to Secure Private-Sector Telecommunications Infrastructure Susan Landau* INTRODUCTION When Google discovered that intruders were accessing certain Gmail ac- counts and stealing intellectual property,1 the company turned to the National Security Agency (NSA) for help in securing its systems. For a company that had faced accusations of violating user privacy, to ask for help from the agency that had been wiretapping Americans without warrants appeared decidedly odd, and Google came under a great deal of criticism. Google had approached a number of federal agencies for help on its problem; press reports focused on the company’s approach to the NSA. Google’s was the sensible approach. Not only was NSA the sole government agency with the necessary expertise to aid the company after its systems had been exploited, it was also the right agency to be doing so. That seems especially ironic in light of the recent revelations by Edward Snowden over the extent of NSA surveillance, including, apparently, Google inter-data-center communications.2 The NSA has always had two functions: the well-known one of signals intelligence, known in the trade as SIGINT, and the lesser known one of communications security or COMSEC. The former became the subject of novels, histories of the agency, and legend. The latter has garnered much less attention. One example of the myriad one could pick is David Kahn’s seminal book on cryptography, The Codebreakers: The Comprehensive History of Secret Communication from Ancient Times to the Internet.3 It devotes fifty pages to NSA and SIGINT and only ten pages to NSA and COMSEC. -

It was then that consideration was given to a proposed agenda for the forthcoming European Heads of Training Conference to be held in Scotland in June that same year. Many such conferences, in all disciplines, provide useful guidance and information to those in attendance. Often however there is little or no resultant legacy in terms of actual and tangible continuous development. -

Offensive Capabilities
GCHQ and UK Mass Surveillance Chapter 5 5 Beyond signals intelligence: Offensive capabilities 5.1 Introduction Documents released by German magazine Der Spiegel provide a much richer picture of the offensive activities of the NSA and its allies, including the UK’s GCHQ.i The global surveillance infrastructure and hacking tools described in the previous chapters are not only used for obtaining information to be fed into intelligence reports and tracking terrorists. The agencies are also developing cyber-warfare capabilities, with the NSA taking the lead within the US armed forces. This militarisation of the internet saw U.S. intelligence services carried out 231 offensive cyber-operations in 2011ii. The UK's National Strategic Defence and Security Review from 2010 made hostile attacks upon UK cyberspace a major priorityiii. It is fair to assume that many countries are following suit and building cyber-warfare capabilities. Der Spiegel terms the development of these aggressive hacking tools as Digital Weapons. In their view D weapons which should join the ABC (Atomic, Biological and Chemical) weapons of the 20th century because of their indiscriminate nature. Here lies a fundamental problem. The modern world with connected global communications networks means that non-state actors such as civilians and businesses are now affected by the agencies’ activities much more frequently than before. The internet is used by everyone – cyberspace is mainly a civilian space – and the opportunity for collateral damage is huge. The papers leaked to Der Spiegel appear to show that signal agencies have little regard for the security and wellbeing of anyone who gets caught in the path of their operations. -
Unclassified Summary Special Study of NSA Controls to Comply With
NATIONAL SECURITY AGENCY/CENTRAL SECURITY SERVICE INSPECTOR GENERAL REPORT Unclassified Summary Special Study of NSA Controls to Comply with Signals Intelligence Retention Requirements 12 December 2019 OFFICE OF THE INSPECTOR GENERAL Pursuant to the Inspector General Act of 1978, as amended, and in accordance with NSA/CSS Policy 1-60, the NSA/CSS Office of the Inspector General (OIG) conducts independent oversight that promotes Agency respect for Constitutional rights, adherence to laws, rules, and regulations, and the wise use of public resources. Through investigations and reviews, we detect and deter waste, fraud, abuse, and misconduct and promote the economy, the efficiency, and the effectiveness of Agency operations. AUDIT The Audit Division comprises three sections: Cybersecurity and Technology, Financial Audits, and Mission and Mission Support. The Division’s audits and evaluations examine the economy, efficiency, and effectiveness of NSA programs and operations; assess Agency compliance with laws, policies, and regulations; review the operation of internal information technology and controls; and determine whether the Agency’s financial statements and other fiscal reporting are fairly and accurately presented. Audits are conducted in accordance with auditing standards established by the Comptroller General of the United States. INSPECTIONS The Inspections Division performs organizational inspections and functional evaluations to assess adherence to regulations and policies and to promote the effective, efficient, and economical management of an organization, site, or function. OIG inspection reports recommend improvements and identify best practices across a broad range of topics, to include mission operations, security, facilities, and information technology systems. The Inspections Division also partners with Inspectors General of the Service Cryptologic Elements and other Intelligence Community (IC) entities to jointly inspect consolidated cryptologic facilities. -
Introducing Traffic Analysis
Introducing Traffic Analysis George Danezis and Richard Clayton January 26, 2007 1 Introduction In the Second World War, traffic analysis was used by the British at Bletchley Park to assess the size of Germany's air-force, and Japanese traffic analysis countermeasures contributed to the surprise of their 1941 attack on Pearl Harbour. Nowadays, Google uses the incidence of links to assess the relative importance of web pages, credit card companies examine transactions to spot fraudulent patterns of spending, and amateur plane-spotters revealed the CIA's `extraordinary rendition' programme. Diffie and Landau, in their book on wiretapping, went so far as to say that “traffic analysis, not cryptanalysis, is the backbone of communications intelligence" [1]. However, until recently the topic has been neglected by Computer Science academics. A rich literature discusses how to secure the confidentiality, integrity and availability of communication content, but very little work has considered the information leaked from communications ‘traffic data' and how these compromises might be minimised. Traffic data records the time and duration of a communication, and traffic analysis examines this data to determine the detailed shape of the communication streams, the identities of the parties communicating, and what can be established about their locations. The data may even be sketchy or incomplete { simply knowing what `typical' communication patterns look like can be used to infer information about a particular observed communication. Civilian infrastructures, on which state and economic actors are increasingly reliant, are ever more vulnerable to traffic analysis: wireless and GSM telephony are replacing traditional systems, routing is transparent and protocols are overlaid over others { giving plenty of opportunity to observe, and take advantage of the traffic data. -
