Steganography Critical Review - 721 Words

Purpose This critical review is to investigate steganographic studies and their methods to either exfiltrate data or defend against data exfiltration. Steganography has one main purpose, to conceal data. Huang’s (2011) method, embedding steganographic data in inactive frames of low-bit rate audio streams went against the norm (Aoki, 2008), (Wu et al., 2006), used active frames of high-bit rate audio streams. Active high-bit rate audio streams have higher least significant bit counts, which presents added frames to conceal steganographic payloads (Huang et al., 2011). Howbeit, Huang (2011) demonstrated a new algorithm he administered to (VOIP) inactive frames of low-bit audio streams, which could carry higher capacity payloads than†¦show more content†¦Nagaraja’s (2011) research purpose was to initiate future studies into defensive measures against botnets. Botnets have a unique ability to coordinate the sending and receiving of new commands to bots that grant the botmaster immense power to execute criminal activities, such as, phishing attacks, DDoS attacks, and ransomware attacks (Nagaraja, et al., 2011). Which have intensified to where presently botnets control hundreds of thousands of hosts and produce millions of dollars in revenue for their creators (Nagaraja, et al., 2011). Contrary to traditional botnets, Stegobot’s communication traffic does not open new communication endpoints between the bots (Nagaraja, et al., 2011). Stegobot takes advantage of social media networks by operating along the edges, while utilizing image steganography techniques to hide covert communication during the interchanging of images among users (Nagaraja, et al., 2011). Network traffic visualization method designed by Mazurczyk (2012) focuses on network anomaly detection principles. Mazurczyk’s main purpose of doing his research was to detect anomalies in network traffic flow, that can cause malicious actions that could compromise network s ecurity. Typical anomaly detection methods instituted across networks focus on discovering illegal activities orchestrated by probable attackers (Mazurczyk, et al., 2012). Current security devices lack the effectiveness needed in today’s immense traffic volumes that need current real-timeShow MoreRelatedSteganography Analysis : Steganography And Steganography1592 Words   |  7 Pages1 Steganography and its introduction Steganography comes from the Greek word â€Å"Steganographia† (ÏÆ'Ï„Î µÃŽ ³ÃŽ ±ÃŽ ½ÃÅ'-Ï‚, ÃŽ ³Ã ÃŽ ±Ãâ€ -ÃŽ µÃŽ ¹ÃŽ ½) which means â€Å"covered writing†. It is the art and science of concealing a secret information within a cover media preventing unauthorized people to know that something is hidden in it, so that the message can only be detected by its intended recipient. Cryptography and Steganography are ways of secure data transfer over the Internet 1.1.1 Cryptography and Steganography CryptographyRead MoreSecurity Issues and Principles Research Paper6107 Words   |  25 PagesSECURITY ISSUES AND PRINCIPLES STEGANOGRAPHY [n. stÉ™ nà ³ggrÉ™fi] Steganography (literally meaning covered writing) dates back to ancient Greece, where common practices consisted of etching messages in wooden tablets and covering them with wax, and tattooing a shaved messengers head, letting his hair grow back, and then shaving it again when he arrived at his contact point. Steganography comes from the Greek steganos, or covered, and graphie, or writing.

Attacks that lead to death or bodily injury, explosions, plane crashes, water contamination, or severe economic loss would be examples. Serious attacks against critical infrastructures could be acts of cyberterrorism, depending on their impact. Attacks that disrupt nonessential services or that are mainly a costly nuisance would not.

Amazon created a website where you could search for products (originally books/music); purchase them remotely; have them shipped to your door; and, review them all on-line. The company evolved into the 3-rd party distribution market which allowed vendors to sell their products through Amazon’s web store and with Amazon handling the transactions for a per-sale commission.
