1 Specific Security Mechanisms. Encipherment is used either to protect the confidentiality of data units and traffic flow information or to support or complement other security mechanisms. … The cryptographic techniques that are used for encipherment are examined in Chapter 5.
What are the security mechanisms?
Security mechanisms are technical tools and techniques that are used to implement security services. A mechanism might operate by itself, or with others, to provide a particular service. Examples of common security mechanisms are as follows: Cryptography.
Which of the following is not the specific security mechanism?
e‐cash is not related to security mechanism. It is also known as electronic cash, it is a digital money product that provides a way to pay for products and services without resorting to paper or coin currency.
Which are pervasive security mechanisms?
– Pervasive security mechanisms, not specific to particular services. Eight types: – encipherment, – digital signature, – access control mechanisms, – data integrity mechanisms, – authentication exchanges, – traffic padding, – routing control, – notarization. Encipherment mechanisms = encryption algorithms.
What is active security mechanism?
Active security is centered around five core capabilities: protect, sense, adjust, collect, and counter. … Part of this is utilizing protection mecha- nisms which provide some level of security against common attack scenarios – e.g., using and configuring a firewall.
Explanation : e‐cash is not related to security mechanism. It is also known as electronic cash, it is a digital money product that provides a way to pay for products and services without resorting to paper or coin currency.
What is meant by steganography?
Steganography is the practice of hiding a secret message inside of (or even on top of) something that is not secret. … It is a form of covert communication and can involve the use of any medium to hide messages. It’s not a form of cryptography, because it doesn’t involve scrambling data or using a key.
What are security design principles?
The security design principles are considered while designing any security mechanism for a system. These principles are review to develop a secure system which prevents the security flaws and also prevents unwanted access to the system.
What is pervasive security?
Pervasive means secure access everywhere applications may be, from SaaS applications in the cloud to legacy applications on-premises, and throughout the infrastructure in between that connects users to those applications.
What are the security attacks?
A security attack is an unauthorized attempt to steal, damage, or expose data from an information system such as your website. Malicious hackers can go about this in a variety of ways, including the ones listed below.
What is the relation between security mechanisms and attacks?
One approach is to consider three aspects of information security: Security attack – Any action that compromises the security of information owned by an organization. Security mechanism – A mechanism that is designed to detect, prevent or recover from a security attack.
