Securing library information system: Vulnerabilities and threats
Threats and vulnerabilities in computers and networks are common nowadays since computers are widely used by the
public. The risks of computer threats and vulnerabilities are high since most computers are connected to the internet.
Library Information Systems is also vulnerable to attack since it is a public access institution. Majority of users are naive when it comes to computer and network securities. Some breaches in Library Information System are intentional and some are unintentional. Risks analysis should be done to find the threats and risks in designing the Library Information System. Threats are made possible due to lack of proper procedures, software flaws and policies. The administrators should anticipate all the possible attacks and their mitigation techniques. In this paper, we will try to address various issues arise from this vulnerabilities and threats. We will also describe how we can reduce and overcome this vulnerabilities and threats
Experimental Case Studies for Investigating E-Banking Phishing Techniques and Attack Strategies
Phishing is a form of electronic identity theft in which a combination of social engineering and web site spoofing techniques are used to trick a user into revealing confidential information with economic value. The problem of social engineering attack is that there is no single solution to eliminate it completely, since it deals largely with the human factor. This is why implementing empirical experiments is very crucial in order to study and to analyze all malicious and deceiving phishing website attack techniques and strategies. In this paper, three different kinds of phishing experiment case studies have been conducted to shed some light into social engineering attacks, such as phone phishing and phishing website attacks for designing effective countermeasures and analyzing the efficiency of performing security awareness about phishing threats. Results and reactions to our experiments show the importance of conducting phishing training awareness for all users and doubling our efforts in developing phishing prevention techniques. Results also suggest that traditional standard security phishing factor indicators are not always effective for detecting phishing websites, and alternative intelligent phishing detection approaches are needed
The development of IT and Telnet and its Impact in Business Security (non Security)
During the years, the people are more hungry for faster doing processes and works. There always is high possibility for loss business and markets by different attacks in different layers. In this paper is presented which are the challenges faced with information security on businesses during the rapid development IT and Telnet. This challenge requires stable technology, the standard platform and especially policies and rules for implementation security steps through those rapid changes in technology. In the paper are presented some of statistical review about the causes of information damage, which are advantages and weaknesses using new information technology. At the end is presented a model with seven attributes which has impact in information system security for every kind of the business.The paper has descriptive-narrative, statistical and inductive nature
A Survey on Wireless Security: Technical Challenges, Recent Advances and Future Trends
This paper examines the security vulnerabilities and threats imposed by the
inherent open nature of wireless communications and to devise efficient defense
mechanisms for improving the wireless network security. We first summarize the
security requirements of wireless networks, including their authenticity,
confidentiality, integrity and availability issues. Next, a comprehensive
overview of security attacks encountered in wireless networks is presented in
view of the network protocol architecture, where the potential security threats
are discussed at each protocol layer. We also provide a survey of the existing
security protocols and algorithms that are adopted in the existing wireless
network standards, such as the Bluetooth, Wi-Fi, WiMAX, and the long-term
evolution (LTE) systems. Then, we discuss the state-of-the-art in
physical-layer security, which is an emerging technique of securing the open
communications environment against eavesdropping attacks at the physical layer.
We also introduce the family of various jamming attacks and their
counter-measures, including the constant jammer, intermittent jammer, reactive
jammer, adaptive jammer and intelligent jammer. Additionally, we discuss the
integration of physical-layer security into existing authentication and
cryptography mechanisms for further securing wireless networks. Finally, some
technical challenges which remain unresolved at the time of writing are
summarized and the future trends in wireless security are discussed.Comment: 36 pages. Accepted to Appear in Proceedings of the IEEE, 201
UK security breach investigations report: an analysis of data compromise cases
This report, rather than relying on questionnaires and self-reporting, concerns cases that were investigated by the forensic investigation team at 7Safe. Whilst removing any inaccuracies arising from self-reporting, the authors acknowledge that the limitation of the sample size remains. It is hoped that the unbiased reporting by independent investigators has yielded interesting facts about modern security breaches. All data in this study is based on genuine completed breach investigations conducted by the compromise investigation team over the last 18 months
PALPAS - PAsswordLess PAssword Synchronization
Tools that synchronize passwords over several user devices typically store
the encrypted passwords in a central online database. For encryption, a
low-entropy, password-based key is used. Such a database may be subject to
unauthorized access which can lead to the disclosure of all passwords by an
offline brute-force attack. In this paper, we present PALPAS, a secure and
user-friendly tool that synchronizes passwords between user devices without
storing information about them centrally. The idea of PALPAS is to generate a
password from a high entropy secret shared by all devices and a random salt
value for each service. Only the salt values are stored on a server but not the
secret. The salt enables the user devices to generate the same password but is
statistically independent of the password. In order for PALPAS to generate
passwords according to different password policies, we also present a mechanism
that automatically retrieves and processes the password requirements of
services. PALPAS users need to only memorize a single password and the setup of
PALPAS on a further device demands only a one-time transfer of few static data.Comment: An extended abstract of this work appears in the proceedings of ARES
