In security engineering, security through obscurity is the practice of concealing the details or mechanisms of a system to enhance its security. This approach relies on the principle of hiding something in plain sight , akin to a magician's sleight of hand or the use of camouflage .
This concept is widely embraced by cryptographers, in contrast to security through obscurity, which is not. Kerckhoffs's principle was phrased by American mathematician Claude Shannon as "the enemy knows the system", [ 1 ] i.e., "one ought to design systems under the assumption that the enemy will immediately gain full familiarity with them".
Open security is the use of open source philosophies and methodologies to approach computer security and other information security challenges. [1] Traditional application security is based on the premise that any application or service (whether it is malware or desirable) relies on security through obscurity .
The theoretical and practical assessment of the security level of CDPs, in other words the detector's ability to detect counterfeit attempts, is an ongoing area of research: In, [ 9 ] practical recommendations on printing stability, taking into account scanning quality of the detector, and managing the security of printing facilities.
Digital steganography output may be in the form of printed documents. A message, the plaintext, may be first encrypted by traditional means, producing a ciphertext.Then, an innocuous cover text is modified in some way so as to contain the ciphertext, resulting in the stegotext.
A web application might make use of User-Agent detection in attempt to prevent malicious users from stealing sessions. This however is trivial to bypass, as an attacker can easily capture the victim's user-agent with their own site and then spoof it during the attack. This proposed security system is relying on security through obscurity.
Preservation of secrets is one of the goals of information security. Techniques used include physical security and cryptography. The latter depends on the secrecy of cryptographic keys. Many believe that security technology can be more effective if it itself is not kept secret. [10] Information hiding is a design principle in much software ...
Some encryption systems will claim to rely on a secret algorithm, technique, or device; this is categorized as security through obscurity. [2] Criticisms of this are twofold. First, a 19th century rule known as Kerckhoffs's principle , later formulated as Shannon's maxim, teaches that "the enemy knows the system" and the secrecy of a ...
