Essay On Blockchain Technology

Cryptography basically makes any transaction secure between two parties. Security is very important, because every person with Bitcoins, their Bitcoins, and every transaction is logged to a public ledger visible by every computer on the

When you are sending your username and password from your computer to bank server it should maintained confidentiality. No third party should be able to hack or share your information. There are few characteristics of confidentiality which are explained in detail as follows: i. Access Control Access control is a type of security technique which is used to identify an authorised user who can view or who will use resources for various data processing activities in a secured environment.

Regular backup of the Magento store: Save regular backup copies on a different server. This saves a copy for oneself in case of any server crashes. Strong password usage: A splashdata revealed '123456 ' as the most commonly used password. It is better to use password with more than ten characters that includes upper case, lower case, numbers and special characters as well. Regular change of password, two-factor authorization is recommended.

Role based access control enables security administrator to easily manage dynamically changing privacy rules. As the permissions are not assigned to the user directly and just inherited through the role, it simplifies such operations as adding a new user or user’s relocation in organization. Performance of composite operations is a considerable advantage of RBAC model compared to DAC and MAC models where only atomic operations are possible. For instance, RBAC enables to make a record “blood sugar level test”, enter a diagnosis, treatment, prescription etc.

Effective password policy is needed to prevent the passwords from being guessed or cracked. The password policy covers the passwords of all types via passwords of users, systems, databases, applications, etc.., while the password policy can be enforced where they are used frequently and by users, it is difficult to enforce for the passwords used in application to application communication. This article talks about the challenges and possible solution to eliminate embedded passwords in application. Credentials used for application to application (A2A) authentication are typically hard-coded or embedded in the configuration files of the applications. These credentials, including SSH keys are easily sought after and can be potentially exploited by cyber attackers when left

To avoid problems of identification and authentication, we need strong authentication over the system. PKG has the main role in authentication because PKG is the trusted third party between users and data owners in the system. PKG gives a public user key (user ID) for each data owner and gives a private key to each user in the system. We will provide two authentication techniques in this simulation; the CAPATCHA and the OTP. The CAPATCHA technique is used to provide the security of the system.

For instance, the UN and Microsoft are partnering and collaborating to design blockchain technology for persons with no physical or electronic identity record. This is an example of how technology enablement can solve other business problems or optimize processes; moreover, by applying blockchain technology to identity systems, this could be a real-world application in a high-risk business area of anti-money laundering, know your customer or KYC where expenses are numerous for banks and the investigation expenditures for regulation and misinformation are also

Barclays faced losses of £1.3 million. The first thing that must be done in order to avoid similar attacks is not much related to cyber security: it is more rigorous physical protection of the computers and servers. Since an attacker like above-mentioned has to firstly get physical access to one of the computers from the network, the first solution is to better control external workers, raise the standards of their inspection and ensure the best possible protection of technological equipment. Another security possibility is to examine every supplier of even the smallest parts of network equipment and to make sure they are reliable, cause their equipment is going to access huge amount of secret data. Moving on to the more cyber-related risks’ solutions, IT specialists should avoid unsecure KVM switches.

However, steganography method is not intended to substitute or replace the cryptography method but rather to complement cryptography. What if we combine both? We can provide more security to our data, right?. So, using cryptography along with the steganography provides more security to our data, that

The key component of Blockchain Technology that is expected to aid in the revolutionization of the insurance market is the previously mentioned “smart contracts”. These contracts that primarily exist on digital wallets and on the cyberweb have the potential to eliminate the need for human administrators when filing an insurance policy (Manelli). Given the commonality of insurance fraud on the side of the policyholder, and the insurance company often outlining conditions in a “vague and non-trivial way”, the elimination of a human administrator would greatly benefit both sides (Manelli). Blockchain has the ability to create more streamline transactions that is clear to all parties without having to deal with the unreliability of a human

now if we use hash and because of its onewayness it is impossible to get back the password. If we use pure hash in the password and encrypt it, it can be broken easily by exhaustive search so that is why we have add some randomness to the password before the hash function is applied. The randomness is stored with the password hash. So now instead of pure hash and pure password we store the hash o/p of password chosen by me and some random number chosen by the system. From now whenever we use the password the system associates with the random number and gives access.

Blended Windows validation is the most secure confirmation. SQL Server validation amid the confirmation secret key is not transmitted in the system messages encoded utilizing the Windows logo. Complex passwords:-Since it is intended to build conceivable passwords. Complexibility applies secret word, the new watchword are sure necessities to be met by no less than 8 characters, not the client name and secret word, date of conception, by 10 premise focuses and is incorporated in the little print.

ANANTH SAI KRISHNA BATTINENI BELLEVUE UNIVERSITY CIS612-T202 – COMPUTER PLATFORMS AND NETWORKING ASSIGNMENT 11.2 Passwords: Passwords provide authorization for a particular user. The correct characters will grant access to operate the system. Every operating system has the option to enable passwords for the computer system to help the user to avoid the unauthorized use of the system. Password Policy:
