Steganography
Steganography is an ancient technique used by spies during the Revolutionary Way to conceal messages. Unlike other methods such as cryptography, which hide the contents of a message, steganography hides the fact that a message is being sent. Today, this technique is used by creators of cyber-espionage and malware tools. Anti-malware software provides very little protection from steganography.
SSH (Secure Shell) is a security protocol used to secure remote login to a server. It provides a secure session for executing programs and transferring files in server/client connections such as email and database access. Therefore, it protects a network from threats such as DNS and IP spoofing and IP source routing.
Credit card fraud is the main issue facing today’s credit companies and banks. Different stakeholders in the finance sector anticipate the enrolment of the next generation of Credit cards. Unlike the traditional cards, which use magnetic strips to store information, the new smart card will use a metal chip technology embedded in it to save the owner’s information. The new technology is designed to reduce fraud by preventing the copying of stolen cards.
National ID creates a secure digital identity for each citizen. These cards open the gate for trusted online services as they offer additional identification through an effective ID checking process in combination with other authentication methods such as passcodes.
Certificate Authority is a third party entity entrusted to make verifications and issue digital certificates to prove it. Digital certification has relied on two algorithms. First is the encryption algorithm called RSA, and the second is a hash algorithm SHA-1. The current model of the Certificate Authority is severely flawed due to the advancements in cryptanalysis. The model is prone to attackers injecting their root keys (spoofing).
