A CEH skills assessment is also available for credential seekers.
Authentication, authorization and auditing are the most important issues of security on data communication.
An authentication system must provide adequate security for its intended environment, otherwise it fails to meet its primary goal. A proposed system should at minimum be evaluated against common attacks to determine if it satisfies security requirements. We classify the types of attacks on knowledge-based authentication into two general categories: In successful guessing attacks, attackers are able to either exhaustively search through the entire theoretical password space, or predict higher probability passwords i.
Guessing attacks may be conducted online through the Information security credentials essay login interface, or online if some variable text e. Authentication systems with small theoretical password spaces or with identifiable patterns in user choice of passwords are especially vulnerable to guessing attacks.
Fake websites which appear very similar to the original ones are being hosted to achieve this. Phishing is an attempt by an individual or a group to get confidential information such as passwords and credit card information from unsuspecting victims for identity theft, financial gain and other fraudulent activities.
Authentication is the first line of defense against compromising confidentiality and integrity.
The various authentication systems were introduced but even they are also suffering from shoulder surfing and screen dump attacks.
As a result of the astonishingly rapid advancement of various kinds of Internet technologies, more information are transmitted to all parts of the world from everywhere through the net. Some of the objects transmitted online may be important secret images, and in such cases the senders have to take information security issues into consideration before they can trustingly enjoy the speed and convenience that nothing in this world but the Internet can offer.
Cryptography is the study of mathematically related techniques to achieve Information Security in terms of confidentiality, data security, entity authentication and data origin authentication.
However, it is not the only means of providing information security. Cryptography includes a set of techniques to achieve confidentiality amongst others when transmitting or storing data.
Traditional cryptographic schemes require end users to employ complex operations for encryption as well as decryption. An alternative to encrypt messages is Visual Cryptography VCwhere the decryption is completely performed by the human visual system.
Visual cryptography is a new technique which provides information security which uses simple algorithm unlike the complex, computationally intensive algorithms of traditional cryptography. This technique allows Visual information pictures, text, etc to be encrypted in such a way that their decryption can be performed by the human visual system, without any complex cryptographic algorithms.
VC schemes hide the secret image into two or more images which are called shares.
The secret image can be recovered simply by stacking the shares together without any complex computation involved. The shares are very safe because separately they reveal nothing about the secret image.A credential is an attestation of qualification, competence, or authority issued to an individual by a third party with a relevant or de facto authority or assumed competence to do so..
Examples of credentials include academic diplomas, academic degrees, certifications, security clearances, identification documents, badges, passwords, user names, keys, powers of attorney, and so on. Security has become an inseparable issue as information technology is ruling the world.
As a result of the astonishingly rapid advancement of various kinds of Internet technologies, more information are transmitted to all parts of the world from everywhere through the net.
In doing so, information security programs need to move from tactical implementations of technology to strategic partners in business (Wylder, ) Although companies were committed to developing a comprehensive information security program, they may not have integrated them into the framework of their businesses.
2 Security of the information systems 1 Workplace protection Computers/registers will be linked and individual credentials will be used to access them, management and IT staff will write credentials; employee logins/logouts will also be recorded.
Information systems commonly use credentials to control access to information or other resources. The classic combination of a user's account number or name and a . Security Information Essay. down without losing any information that could harm us if in another person’s hands. We need to keep our most valuable assets safe and one way to do this is to tighten our systems security by limiting certain access to these assets via computer systems.
