We prefer a very broad definition, saying that a system is secureif its owner ever estimated its probable losses from adverse events, such as eavesdropping.We say that a system issecuredif its owner modified it, with the intent of reducing the expected frequency or severity of adverse events. These definitions are in common use but are easily misinterpreted. An unsupported assertion that a system is secure, or that it has been secured, does not reveal anything about its likely behavior. Details of the estimate of losses and evidence that this estimate is accurate are necessary for a meaningful assurance that a system is safe to use. One form of assurance is a security proof , which is a logical argument demonstrating that a system can suffer no losses from a specific range of adverse events if the system is operating in accordance with the assumptions (axioms) of the argument. continue reading… **Content:** 1 A Framework for System Security … 3 2 Public-Key Cryptography . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21 3 Elliptic Curve Cryptography . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 35 4 Cryptographic Hash Functions . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 59 5 Block Cipher Cryptanalysis . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 81 6 Chaos-Based Information Security . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 91 7 Bio-Cryptography . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 129 8 Quantum Cryptography . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 9 Intrusion Detection and Prevention Systems . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 177 10 Intrusion Detection Systems . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 193 11 Intranet Security via Firewalls . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 207 12 Distributed Port Scan Detection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 221 13 Host-Based Anomaly Intrusion Detection . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 235 14 Security in Relational Databases . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 257 15 Anti-bot Strategies Based on Human Interactive Proofs . . . . . . . . . . . . . . . . . . . . . 273 16 Access and Usage Control in Grid Systems . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 293 17 ECG-Based Authentication . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 309 18 Peer-to-Peer Botnets . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 335 19 Security of Service Networks. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 351 20 Network Traffic Analysis and SCADA Security . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 383 21 Mobile Ad Hoc Network Routing . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 407 22 Security for Ad Hoc Networks . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 421 23 Phishing Attacks and Countermeasures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 433 24 Chaos-Based Secure Optical Communications Using Semiconductor Lasers . 451 25 Chaos Applications in Optical Communications . . . . . . . . . . . . . . . . . . . . . . . . . . . . 479 26 Security in Wireless Sensor Networks . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 513 27 Secure Routing in Wireless Sensor Networks . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 553 28 Security via Surveillance and Monitoring . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 579 29 Security and Quality of Service in Wireless Networks . . . . . . . . . . . . . . . . . . . . . . . 603 30 Low-Level Software Security by Example . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 633 31 Software Reverse Engineering . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 659 32 Trusted Computing . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 697 33 Security via Trusted Communications. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 719 34 Viruses and Malware . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 747 35 Designing a Secure Programming Language . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 771 37 Multimedia Forensics for Detecting Forgeries . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 809 38 Technological and Legal Aspects of CIS . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 829 Go To **Base64** & Decode: ```auto aHR0cHM6Ly9tZWdhLm56L2ZpbGUvamJwaERBTFIjbGg3cG1Ndm1yUC1tOFpWMlBBZTdTVl9tWmxKMWpXNV9WMGp1U2J0bVE5MA== ``` **Enjoy!**
