Nt1310 Unit 3 Data Analysis

It is risky. Online criminals and hackers could easily crack such passwords. However, you can use the first letter of each word in a long phrase to create strong passwords. You can also strengthen such passwords by making some letters uppercase and by swapping out some letters with numbers and symbols 7. Don’t use passwords that are less than eight characters.

At least one character should be a Digit. 4. Symbols and Non alphabetic characters. Reversible Encryption:

Public key cryptography is an asymmetric method that use a pair of keys for encryption: a public key which is used to encrypt data, and private, or secret key is used to decryption. It requires that a person must have a pair of public key and private key. The public key is distributed in the open so that anyone wishing to communicate with that in a secure way than he can use the receiver’s public key to convert the plaintext into cipher text. This cipher text cannot be converted into same plaintext using same public key. Therefore, there is no issue if some other person knows about public key.

The blocks and their content are protected by cryptography, so transactions cannot be destroyed or forged. This means that the ledger and network are trusted without an intermediary. Cross-border Payments The objective for financial institutions should be to deliver cross-border payment services in near real time and at a more competitive price. While maintaining their margins

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.

If the request is valid then it is further checked for other attacks, otherwise it is blocked and stored in the log with the attack type that is found in that request. In HTTP request smuggling attack, a malicious request contains multiple start lines that are not allowed in one HTTP request (violation of RFC 2616). When the hacker tries to assign multiple start lines to one request, it will be detected by the system analyzer and reported as an HTTP request smuggling attack. A buffer overflow is the computing equivalent of trying to pour two liters of water into a one-liter pitcher, some water is going to spill out and make a mess.

CHALLENGES OF PROLIFERATION BIOMETRIC TECHNOLOGY Despite the numerous benefits of deployment of biometric technology to identification systems, it major disadvantage is that it is prone to vulnerabilities attacks either at the user interface or between modules or on the database template. Some of these attacks (Anthony & Mary, 2011)are highlighted as follow:  Replay attacks  Spoofing  Tampering  Substitution attacks  Trojan Horse attacks  Overriding yes/no  Masquerade attack

Federated identity management makes use of an authentication mechanism known as single sign-on. Users only make use of one set of credentials and are automatically granted access to multiple systems. Federated identity management introduces increased concern for security and privacy as “it shares valuable information across domains using loosely coupled network protocols” (Maler & Reed, 2008). The internet is an interconnection of networks and is not owned by anyone, therefor anything that operates on the internet is a concern for security.

Abstract Now a days, security of the confidential information of the organization or an individual become a serious issue. Because of vulnerability of system allow to unauthorized person to access the confidential information or data . Because of unauthorized access the confidentiality of information get break. So, biometrics is a good technique to maintain the security of the confidential data.

Cryptography is a technique or method to secure personal data from unauthorized user. In cryptography two types of operation are performed. (i) Encryption and (ii) Decryption. To encrypt and decrypt data a secret key is used. After encryption original data is converted into another format known as cyphertext, which is not easy to understand.

Q5) (a) Password policy: SQL Server verification server login and secret key approach can apply. Login and secret word are not the same regarding security is extremely viable. SQL new businesses • SQL server administration studio gives three choices for the above logins • Implement secret key strategy • Keeping in mind the end goal to keep up the security of information, we can change the secret key or are made, when the need to put a touch befuddling. • at the point when the approach is empowered all the prerequisite ought to be meet • Eight characters ought to be in the secret word •

The government, criminals, ... Although the exit node providers don 't know who is sending & requesting the traffic being redirected through their node, they can use the data they can "phish" this way against you anyway. Furthermore it is pretty easy to figure out who you are by simply interpreting the recorded packages. An alternative to Tor and similar services are VPN services.

\section{Building Blocks} \subsection{Access Structures} \textbf{Definition 3.8.}(Access Structure\citeup{beimel1996secure}) \emph{Let $\{P_1, P_2,...,P_n\}$ be a set of parties. A collection $\mathbb{A}\subseteq 2^{\{P_1,P_2,...,P_n\}}$ is monotone if $B\in\mathbb{A}$ and $B\subseteq C$ implies $C\in\mathbb{A}$. An access structure is a monotone collection $\mathbb{A}$ of non-empty subsets of $\{P_1,P_2,...,P_n\}$, i.e., $\mathbb{A}\subseteq 2^{\{P_1,P_2,...,P_n\}} \setminus\{\emptyset\}$. The sets in $\mathbb{A}$ are called the authorized sets, and the sets not in $\mathbb{A}$ are called the unauthorized sets}. In our settings, attributes will play the role of the parties such that the access structure $\mathbb{A}$ will contain the authorized

1.3 How do local area networks (LANs) differ from wide area networks (WANs) and backbone networks (BNs) Local area networks are limited within an organization Wide area networks extend over a large geographical distance and may be privately owned or rented Backbone network are the part of network infrastructure that feeds the connected networks 1.8 Describe the seven layers in the OSI network model and what they do. Application – this layer is specific to applications and provides services such as email, network software services and file transfers Presentation - In this layer, the data is formatted in a schema that network understands, and also manages data encryption and decryption Session – this layer establishes and controls the data communication between
