The nowadays ubiquitous and effortless digital data capture and processing capabilities offered by the majority of devices, lead to an unprecedented penetration of multimedia content in our everyday life. To make the most of this phenomenon, the rapidly increasing volume and usage of digitised content requires constant re-evaluation and adaptation of multimedia methodologies, in order to meet the relentless change of requirements from both the user and system perspectives.
The methods for human identity authentication based on biometrics â€“ the physiological and behavioural characteristics of a person have been evolving continuously and seen significant improvement in performance and robustness over the last few years. However, most of the systems reported perform well in controlled operating scenarios, and their performance deteriorates significantly under real world operating conditions, and far from satisfactory in terms of robustness and accuracy, vulnerability to fraud and forgery, and use of acceptable and appropriate authentication protocols. ...
As multimedia-enabled mobile devices such as smart phones and tablets are becoming the day-to-day computing device of choice for users of all ages, everyone expects that all mobile multimedia applications and services should be as smooth and as high-quality as the desktop experience. The grand challenge in delivering multimedia to mobile devices using the Internet is to ensure the quality of experience that meets the users' expectations, within reasonable costs, while supporting heterogeneous platforms and wireless network conditions. ...
"This book covers not just the glamorous aspects such as the intrusion act itself, but all of the pitfalls,contracts, clauses, and other gotchas that can occur. The authors have taken their years of trial and error, as well as experience, and documented a previously unknown black art."
-From the Foreword by Simple Nomad, Senior Security Analyst, BindView RAZOR Team Penetration testing--in which professional, "white hat" hackers attempt to break through an organization’s security defenses--has become a key defense weapon in today’s information systems security arsenal.
The Threat Analyzer is used for the analysis of the alerts detected by your McAfee®
Network Security Platform [formerly McAfee®
] Sensors as well as those
processed by an integrated Host Intrusion Prevention Server. The Threat Analyzer works
in conjunction with the policies applied to your McAfee®
Network Security Sensor and Host
Intrusion Prevention Sensors. For more information on policies, see IPS Configuration Guide.
Network reconnaissance cannot be prevented entirely. If Internet Control Message Protocol
(ICMP) echo and echo-reply is turned off on edge routers, ping sweeps can be stopped, but
at the expense of network diagnostic data. However, port scans can easily be run without
full ping sweeps; they just take longer because they need to scan IP addresses that might
not be live. Intrusion detection systems (IDSs) at the network and host levels can usually
notify an administrator when a reconnaissance attack is underway.
