Sexual difficulties can have a negative impact on sexual and psychological wellbeing and interpersonal relationships. Interactive Digital Interventions (IDIs) for sexual difficulties have the potential to provide a convenient, wide-reaching and cost- effective alternative to face-to-face therapy, but research in this area is in its infancy. Currently little is known about their effectiveness, reach and acceptability. Aim To investigate the use of the internet to deliver psychotherapeutic interventions for sexual difficulties, and determine their effectiveness, reach and acceptability Methods 1. A systematic review of the effectiveness of IDIs for adults with sexual difficulties. 2. A secondary data analysis of the data from the third National Survey of Sexual Attitudes and Lifestyles to investigate the potential reach of IDIs and explore the characteristics of people who seek help for their sex lives 3. A qualitative interview study to explore users’ views of an IDI for sexual difficulties before and after using one. Results IDIs can be effective for sexual difficulties, but the current evidence-base is small, and contains studies that are methodologically flawed, so more research is needed to be sure of these effects. With approximately 427,000-762,000 British people reportedly distressed about their sex lives and looking for information and support online, it appears that IDIs have considerable potential to reach their intended audience. The sextherapylondon website appeared to be acceptable to users as it met many of their wants and needs with regards to features, design, usability, user experience and perceived outcomes. Conclusion Overall, this thesis suggests that IDIs could have a valuable place in providing an alternative help source for people with sexual difficulties, especially in the light of further cuts to sexual health services. 4 Conference presentations Hobbs, L., Bailey, J., & Murray, E.

In addition, large-scale cyber attacks have enormously ma- tured and became capable to generate, in a prompt manner, significant interruptions and damage to Internet resources and infrastructure. Denial of Service (DoS) attacks are perhaps the most prominent and severe types of such large-scale cyber attacks. Furthermore, the existence of widely available encryption and anonymity techniques greatly increases the difficulty of the surveillance and investigation of cyber attacks. In this context, the availability of relevant cyber monitoring is of paramount im- portance.

  • Government-Wide Cyber Security
    White Paper Government-Wide Cyber Security Leveraging Network Intelligence Technology April 2009 Enabling True Network Intelligence Everywhere White Paper Government-Wide Cyber Security Executive Summary Governments and multi-government organizations can better support IT network security across applications and government functions with a common technology platform leveraging Network Intelligence building blocks. IT security continues to be the greatest challenge facing government CIOs worldwide. Most experts agree that governments require stronger partnerships between the public and private sectors for both better protection of government IT systems from intruders and for greater visibility into operators’ network traffic to fight crime. However, government systems and intelligence activities constitute a very sensitive information environment. Governments must proceed with caution when forming technology partnerships for hardening their IT network security. Melissa E. Hathaway, who in February 2009 was named to be the Obama Administration’s top cyber security official, points out how government IT organizations should be asking questions such as: Who designed the security technology? Who built the technology? Who operates and maintains the technology? Who upgrades the technology? Who retires the technology?1 Commercial-Off-The-Shelf (COTS) products are not always suited for government network security needs. Governments can better support network security across applications and government functions with a common technology platform consisting of reusable technology building blocks. Such a global approach would enable government organizations to control the development, performance and maintenance of security applications, while preserving the confidentiality of security mechanisms for detecting cyber criminals and protecting information. Qosmos Network Intelligence provides this capability. Qosmos Network Intelligence provides this capability with technology to extract detailed IP metadata from network traffic.

    OPEN SOURCE INTELLIGENCE TOOLS AND RESOURCES HANDBOOK 2020 OPEN SOURCE INTELLIGENCE TOOLS AND RESOURCES HANDBOOK 2020 Aleksandra Bielska Noa Rebecca Kurz, Yves Baumgartner, Vytenis Benetis 2 Foreword I am delighted to share with you the 2020 edition of the OSINT Tools and Resources Handbook. Once again, the Handbook has been revised and updated to reflect the evolution of this discipline, and the many strategic, operational and technical challenges OSINT practitioners have to grapple with. Given the speed of change on the web, some might question the wisdom of pulling together such a resource. What’s wrong with the Top 10 tools, or the Top 100? There are only so many resources one can bookmark after all. Such arguments are not without merit. My fear, however, is that they are also shortsighted. I offer four reasons why. To begin, a shortlist betrays the widening spectrum of OSINT practice. Whereas OSINT was once the preserve of analysts working in national security, it now embraces a growing class of professionals in fields as diverse as journalism, cybersecurity, investment research, crisis management and human rights. A limited toolkit can never satisfy all of these constituencies. Second, a good OSINT practitioner is someone who is comfortable working with different tools, sources and collection strategies. The temptation toward narrow specialisation in OSINT is one that has to be resisted. Why? Because no research task is ever as tidy as the customer’s requirements are likely to suggest. Third, is the inevitable realisation that good tool awareness is equivalent to good source awareness. Indeed, the right tool can determine whether you harvest the right information.

November 2010 Berlin 2010 D 83 ii iii Abstract The Domain Name System (DNS) is a critical infrastructure of the Internet because almost all applications that run on Internet-connected machines depend on the name resolution service it provides to work. The DNS consists of three components: the domain name space, the name servers, and the clients, formally referred to as resolvers. Due to its critical nature, the domain name space and the name servers have been for many years very attractive targets for attackers seeking to inflict widespread damage. To deal with this state of affairs, substantial attention and investment have been directed at enhancing the security of and protecting the DNS to ensure its continuous, reliable and efficient operation. This, in conjunction with a notable shift in the motivation and profile of attackers have led in recent years to a considerable change in the Internet attack landscape. Attacks have gradually become more sophisticated and focused, and financial gain has evolved into the major driving force behind them. In this new era, attackers have realised that misusing the name servers or exploiting the name resolution service comes with greater damage or economic profit than directly attacking the components of the DNS or disrupting the name resolution service.
