NS2 Projects on Network Security

Types of Network Security Attacks:

We handled and resolved various types of security attacks in B.E/ B.Tech projects are:

• Passive Attacks:

We handle this attack. It occurred as learning information from transmission content, eaves dropping on transmission, monitoring frequently are followed by this attack.

• Active Attack:

We handle this attack but it is too complicated to prevent user identity. Attacker try different password to access (or) modify network information

Network Security Requirements:

We implement network security projects with following requirements which mentioned from Springer papers are:

• Provide Available Parameter.
• Maintain Confidentiality.
• Need Strong Encryption Algorithm.
• Provide High Security.
• Secret Key Maintained.

Difference between Traditional and Modern Cryptosystem:

• Traditional Cryptosystem:

We implement this system which uses cryptography algorithm for encryption of secure information. This system composed of cipher-text, plain text, and encryption and decryption algorithm.

• Modern Cryptosystem:

We use this method to shift the ordering of letters by efficient encryption algorithm. Information consider as digital format and key length are taken to encrypt and decrypt process.

Security Protocols for Network:

To ensure a security in our project, we use various security protocols which are easily implemented and understood by students are:

• Secure Socket Layer Protocol:

Public key technology and digital certificate are ensured to authenticate certificate from server for secure transactions over internet. It installs the components for secure transmission.

• Secure Electronic Transaction:

SET protocol ensure authentication certificate for customer, merchants and banks. It maintain digital wallet to store card information and identification and not see customers information which transferred to merchant’s bank.

Types of Security Attacks in Networking:

We mentioned various security attacks in networking are:

• Denial of Service Attack:

We handle this attack by various processes. It blocks the network server and inform user as legitimate message, alter route table and share attacks to many computers.

• Viruses:

Viruses are computer program which corrupt network (or) it embedded in other files to destroy the network communication.
