Nt1310 Unit 3 Network Security

Password policies are in place for a variety of reasons. These policies are to establish a standard for strong password creation, the protection of the passwords, and the frequency at which it is changed. The Virtual Private Network (VPN) extends a private network across a public network like the internet. It enables users to send and receive data across shared or public networks. This is done as if they were directly connected to the private network.

Security monitoring allows: 1. Effective security protection on the network 2. Controlling of various malicious activities on the network 3. Detailed understanding of security infrastructure of the network

It can also use to authentication the data and identify the sources of messages that received from sender. Email authentication is important to prevent unauthorized messages come in and make damaging to hack your personal information. Chapter 4 Proposed Technique Proposed technique is the technique that can be suggest to users to solving the existing problems at above.

P8.4. a. Preventive controls such as authentication so anyone trying accessing the system has to provide credentials and verify their identity, encryption so sensitive information cannot be accessed, and have a strong internal environment that educates employees on security measures. Detective controls such as log analysis could be used to show determine if someone is trying to log on to a system and is unsuccessful. Corrective controls such as having an effective CIRT that can access the laptop and block or delete important information so the theft cannot access the laptop.

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

When encryption and physical data protection is in place for individuals who use their personal mobile devices to communicate private health information or to access sensitive patient data in the course of their work. Keeping text messaging HIPAA compliant is done by “secure texting”, which is a process in which encrypted messages are transmitted from a secure server which stores all sensitive data locally, and which prevents the cell phone network that carries the message from keeping a copy. Secure messages can be accessed at any time in any location where there is an Internet connection, unless they have been programmed to expire automatically or recalled to protect the integrity of private health information. HIPAA is a set of basic national privacy standards and information practices. It protects the privacy of all patients and residents of the United States who receive any kind of healthcare services.

Cryptography is one of widely used technique of secret writing which is the term used for data and information security and protects that information from various attacks. Cryptography is the process of converting a known text or plaintext into a human unreadable format called cipher text by encoding the original message using some encoding technique. Security is concerned with the protection of the network and data transmission over the network. Data Security is the most essential aspect of secure data transmission over the network. But to achieve complete data security is a challenging issue of data communication.

If you think your phone is secure, it is still vulnerable to pilfer your data. Now a day’s hacker does not need physical access to the phone. They can infect your device with the virus or steal your personal information using malicious applications remotely. You can keep away your phone from hackers by taking the 10-smartphone security steps. Step 01:

We must keep a check and monitor our applications from time to

In this vein, it is discussed the importance of having a control banks' public and private data, following principles serve as landmarks in the data collection and its purpose as the principle of correction in collecting and processing information, the principle of accuracy data collected, the principle purpose of data collection, the principle of publicity of the databases, the principle of individual access and the principle of security. It is salutary that the user is aware that the data entered in the computer system because the storage capacity in clouds, it becomes almost permanent, and the privacy is not assured. The inviolability of the confidentiality of data is related to the fundamental right to privacy.

4. Strong collision: given a message M1, it is not possible to find two distinct messages such that h (M1’) = h (M1). The probability of this collision is 2n/2.

Which method does not involve password travel across the internet ? a) E commerce b) Manipulation system c) Challenge–response system d) Responce system Answer:c 8. In Assymmetric Encryption, a message encrypted with the Public Key only be decrypted with the receiver’s appropriate Private Key. Justify?

The interlocking door control system only allows a single individual at a time to enter the “trap”, the individual is than required to provide credential such as smart card, biometric verification, PIN and key fob in order to gain access to company grounds. All traffic in and out of the mantrap can be monitored via surveillance cameras for auditing and log activity. Another alternative would be the implementation of a security guard and surveillance cameras, which is a lower cost option but poses higher risk of theft

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.

Explain the growth trend in this area With any network, you need to provide several resources for your users, but chief among them is security. Security starts with ensuring that only the right people have access to your network, and that they only have access to what they are supposed to have access to. Next comes the ability to ensure that communications are protected, and systems are inspected for vulnerabilities and threats. Identity as a Service (IDaaS) is a solution that provides authentication infrastructure as a cloud service. IDaaS is a service that provides Identity and Access Management (IAM) functions for a company in place of a local solution like Active Directory.
