Network Security Projects.
Network Security Projects aims to protect and transmit secure data in a secretive manner and safeguard information from hackers. It allows the information to be accessed only by the authentic user. The service of maintaining user action record is called as accountability and it is also known as AAA expanded as Authentication, Authorization, and Accountability. Network security projects consist of number of policies and rules adopted by a network administrator to prevent unauthorized access, attack, misuse, and modification or denial computer network. Network Security Project relates in explaining network security complexities and gives out answers for network security issues. It is mostly used in networking and computer system. Network security projects are required to all governments, academic organization and business. These areas use data communication by inter connected network. Network security project goal is to protect database files, server and information. Attacking and hacking is prevented using network security projects.
Objectives of Network security:
Main Objective of network security projects is to maintain data integrity and confidentiality of information in a network.
Data integrity: Programs and information network security assures that they are changed by authorized user are changed by authorized user.
Confidentiality: It is classified as privacy and data confidentiality. For authorized user influence or individual control is provided under privacy. An assurance of keeping up confidential information from unauthorized users is provided in data confidentiality.
Network Security Architectures.
Services, network security attacks and mechanism useful ideas are provided.
Security Services: It is referred as enhancing the data processing system’s security. By a protocol layer of communicating open system x.800 provides security services. Specific kind of protection services are provided against security attacks.
Peer entity authentication Confidences of logical connection of entities are provided.
Data origin authentication A connectionless transfer communication provides data that comes from authenticated source and received by authenticated destination.
Access control: Access control refers to prevention of unauthorized access of resources.
Data Integrity: Assurance of received data sent by an authorized entity.
Data confidentiality: Protection mechanism is provided for providing secure maintaining of data from unauthorized user.
Non repudiation: Protects from denial of service attacks.
Security mechanism:This is the process of Preventing or recovering data from security attack.
Security Attacks: Data communication or organization information that is affected by malicious user or virus is known as security attacks.It is classified as
Active attacks:The message can be modified or create false stream over the data stream. They are of 4 categories. They are
- Modification of messages.
- Denial of service.
Passive attacks:Here the information resource is not attacked but information from system is used. It occurs in monitoring, eavesdropping or data transmission.Two types of hacking methods are carried out in passive attacks
- Traffic analysis.
- Observing message content.
Challenges faced in Network Security Projects.
Major necessitous as authentication, non repudiation and confidentiality must be satisfied under network security it is a complicated task as security mechanism do not meet all requirements. Security algorithm develops specific security problems.A complex task is creation, distribution and production of secret key information. Information system in security must be monitored periodically which is a tough job in today’s environment.
Issues of Network Security:
Threat: The accessibility of information is distributed by threats.
External Threat: Hackers try to obtain secured information.
Internal Threat: It affects the network’s security level.
Attack: Attacks are purposeful action done to bring to the system.
Active Attack: Viruses are added to obtain information from outside.
Passive Attack: It monitors and tries to get the information by using password.
Vulnerability: The weakness within the computer is called as vulnerability.
Configuration Weakness: Misconfiguration or faulty configured may lead for attack.
Security Policy Weakness: Misuse of security plans lead to this weakness.
Technology Weakness: Weakness of technology like that of operating system, network and protocol.
Impacts of Network Security:
Interposition: allows user to access host network without password.
Denial of Service: collision of system because of high traffic during packet transmission.
Repudiation: the risk of getting external network to connect with internal network.
Crime information: Rogue users can hack and steal the information.
General attacks entered in Network security systems.
- DOS (Denial-of-Service) attack.
- Identity theft.
- Viruses, worms and Trojan horses.
- Data interception and theft.
- Hacker attacks.
- Spyware and adware.
- Zero-day attacks.
How to Prevent attacks in network security Projects?
Network security projects use the following methods to prevent attack occurred from networks:
- IPSec and SSL
- Anti-Malware software
- Cryptographic systems etc.
Components of Network security projects
- For identifying quick spreading threats like zero-day or zero-hour attacks includes intrusion prevention system (IPS)
- Use anti-virus and anti-spyware
- For providing secure remote access enable virtual private network (VPNs)
- To block unauthorized access to the network utilize firewall concepts.
Attacks are prevented using Network security projects.
- DoS and ip spoofing.
- Email bombing.
- DoS and cookies.
- Systems Boot Record Infectors.
- SQL injection attack.
Benefits of Network Security Projects.
- Shared information is protected from malicious users.
- Private networks are created to secure important information.
- Client’s data are protected from existing networks.
Applications of Network Security projects.
- Applications are developed for access control.
- Email protection from unauthorized user.
- System management.
- Information secured for teleconferencing.
- Ip security.
- Web security standards.
- Authentication applications.
- Data integrity.
- Confidential Information Transformation.
Extraordinary work by the faculty.They are very experienced and made me understand the ideas clearly
I have no idea about my projects. They provide a special training about network security projects.
Excellent project work done by the staffs.I liked your project center very much.Thanks a lot for your support
Doubts were cleared by the staffs patiently.Support was excellent.Thanks a lot.
