PROTOCOL MECHNISM FOR SECURITY ppt
This document discusses wireless sensor networks and network security. It defines what a wireless sensor network is and common applications. It then discusses protocols used for communication between nodes, including what they are, how they perform tasks, and their role in security. The document outlines various security threats like denial of service attacks, and mechanisms to protect against them, including cryptography, key management protocols, and encryption protocols. It emphasizes the importance of security protocols for wireless sensor networks.
Week13
Networks use various forms of encryption like file, data, and link encryption to securely transmit information. File encryption protects central server and storage files by requiring an encryption key to read or modify them. Data encryption uses a pseudorandom key to scramble real data within transmitted network packets, obscuring it from unauthorized access. Additionally, link encryption can be applied between routers to fully encrypt entire data streams as they cross networks.
Week13
Encryption provides security across central servers, routers, firewalls, and VPNs. Central servers encrypt files to protect them from being read or changed. Routers distribute encrypted data packets. Firewalls are certified to slow the spread of fire and contain information. VPNs encrypt links, often across private networks and the Internet.
Transport layer security (tls)
Transport Layer Security (TLS) is the successor to Secure Sockets Layer (SSL) and ensures privacy and security between communicating applications on the internet. TLS encrypts data transmission, works with most browsers and servers, supports flexible encryption algorithms, and is easy to deploy on many systems transparently. It operates directly above TCP and establishes an encrypted connection by negotiating a cipher suite and exchanging certificates and keys between the client and server. Once handshake is complete, both sides can communicate securely until closing the connection. TLS version and cipher suite used can be viewed in browser.

Towards a Security-aware Network Virtualization
This document proposes approaches for improving security in network virtualization. It identifies new security threats that can occur when networking resources are shared with untrusted parties and virtualized network equipment runs untrusted code. The document's proposed approaches are:
1) ELSSA (Extended Label Stream Switching Architecture), a base protocol that combines label forwarding and security protocols like MPLS and IPSec to allow recursive instances for network abstraction.
2) TASec (Traffic Analysis Security), which provides traffic analysis resistance through separate encryption of labels and payloads and an entangled encryption scheme with constant packet sizes, reducing overhead compared to onion routing.
3) The combination of ELSSA and TASec is proposed to meet
Man in The Middle Attack
A man-in-the-middle (MITM) attack intercepts communications between two parties by relaying and controlling messages between them. The attacker eavesdrops and potentially modifies the communication by replacing the keys for their own. This allows them to intercept sensitive transmissions like passwords or financial transactions. A MITM works by spoofing the MAC address of the target to intercept and manipulate traffic between the target and other devices on the network, such as a router. Encrypted connections and careful certificate verification can help prevent MITM attacks.
HTTP vs HTTPS Difference
HTTP is a protocol for sending and receiving data between a web server and client like web browsers. It allows web pages and other files to be transferred but the data is not encrypted, so it can be viewed or intercepted by others. HTTPS encrypts this data transfer using SSL certificates to provide a secure connection and prevent sensitive information from being stolen. The main advantages of HTTPS are that it helps build trust, provides security, and qualifies websites for features like AMP pages.
Algorithms for network server anomaly behavior detection without traffic cont...
A problem of anomaly behavior detection for network server without traffic inspection is discussed. An importance of the problem is proved in a context of broad use of typical communication engines in servers and Internet of Things. A cross-correlation function for request-response characterization is introduced. An applicability of this approach was probed on SSH, DNS, HTTP and HTTPS real traffic. Two algorithms are provided to work with cross-correlation functions: one is based on Pearson correlation coefficient and another based on neural network one class classifier. Traffic of real HTTP and HTTPS servers is used to investigate algorithms and analyze their results. Key features and important parameters of both algorithms are highlighted. Not typical request-response events detection is demonstrated on test traffic series. Actuality and lightweight quality of the approach are emphasized regarding intrusion detection system implementation for typical servers, M2M and IoT applications.
Network traceability
The document proposes a network coding based scheme to preserve privacy against traffic analysis attacks in multi-hop wireless networks. It addresses the disadvantages of existing systems that do not provide message confidentiality or prevent packet flow traceability. The proposed scheme uses homomorphic encryption of global encoding vectors to provide both packet flow untraceability and message content confidentiality, thwarting traffic analysis attacks while maintaining the benefits of random linear network coding.

This document describes a secure cloud storage system that uses erasure coding and threshold proxy re-encryption to allow data forwarding while maintaining security. The system encrypts, encodes, and distributes user data across multiple storage servers. It also allows users to securely forward their data to other users without retrieving it from the storage servers first. The proposal analyzes parameters for the number of data copies and storage servers queried to balance storage needs and robustness.
Encryption
It is about Encryption like Symmetric, Asymmetric and Hashing and what are these, how are these working and what are differences exist among these.
Encrytion ppt
encryption is the process of encoding a message or information in such a way that only authorized parties can access it and those who are not authorized cannot. Encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor.
Encryption
Encryption encodes information to protect it from unauthorized access. It involves two processes - encryption scrambles the information using an algorithm, while decryption reverses the process to restore the original information. There are two main methods: symmetric key encryption uses the same key to encrypt and decrypt, while asymmetric key encryption uses separate public and private keys.
Wiretapping
This document discusses packet sniffing and network monitoring. It defines a sniffer as a tool that can capture and display network data in transit. It explains that sniffers work by putting network adapters in promiscuous mode to listen to all traffic, not just traffic addressed to that system. The document outlines different types of sniffing attacks and protocols that are vulnerable when not encrypted. It also provides examples of sniffer tools and ways to detect and protect against sniffing on a network, such as using encryption, static configurations, and intrusion detection systems.
Man in-the-middle attack(http)
A man-in-the-middle attack intercepts communications between two systems by compromising the connection, such as the TCP connection between an HTTP client and server. Tools like Wireshark and tcpdump can be used to perform a man-in-the-middle attack on HTTP traffic in a LAN network by analyzing packets at the deepest level. Wireshark is used in this scenario to attack vulnerabilities between network nodes.
Man in-the-middle attack(http)
The document discusses man-in-the-middle attacks using HTTP and Wireshark. A man-in-the-middle attack intercepts communications between two systems by compromising the connection between a client and server. Wireshark is a network protocol analyzer that can be used to launch man-in-the-middle attacks on HTTP traffic by inspecting packets at a deep level within a local area network. The attacks are effective because HTTP and its data transfers use plain ASCII text which can be easily read.
Cryptography and attacks ins
The document defines different types of attacks on cryptography systems including passive and active attacks. Passive attacks attempt to learn information without affecting system resources, while active attacks try to alter system operations. The document also discusses cryptography, defining it as the practice of hiding information and converting plain text into unintelligible cipher text. Symmetric key cryptography uses a shared key for encryption and decryption, while asymmetric key cryptography uses public and private key pairs.
How Encryption Works
Encryption is used to encode information so that only those with the key can decode it, providing security for computers and information sent over the internet. There are two main types of encryption - symmetric key encryption where both sides use the same key, requiring the key to be installed on both computers beforehand, and public key encryption which addresses issues with symmetric key using a two-key system that allows encryption and decryption with different keys. A 1976 paper introduced public key encryption as an improvement over symmetric key encryption.
Encryption ppt
Encryption is the process of encoding messages or information so that only authorized parties can read it. There are two main types of encryption: symmetric key encryption which uses the same key to encrypt and decrypt, and asymmetric key encryption which uses a public key to encrypt and a private key to decrypt. While symmetric encryption is faster, asymmetric encryption is more secure since it does not require sharing the same key. Encryption is widely used to provide authentication, privacy, integrity, and accountability of data.
Mexicanos part dos
By 1776, the majority of the population in New Mexico identified as mestizo, of mixed Spanish and indigenous ancestry, as interracial marriage between Spanish colonists and indigenous peoples became common. The Spanish explored and settled the Far North of New Spain, now the Southwestern United States, establishing missions to convert indigenous groups to Christianity and exploiting their labor, while trade developed between Spanish settlers and mestizos with Americans arriving after independence.
Hollywood principle
This document discusses the Hollywood principle, which is a software design pattern that inverts control of objects. It involves a two-step process where objects first register themselves, then wait to be called back later. This pattern results in low coupling between objects and observers. It draws an analogy between actors/actresses being observed in films to objects being observed in code through the Observer design pattern.
Mexicanos p5
This chapter discusses Mexican immigration to the US for labor intensive jobs with low wages in farming, mining, and railroad construction from the early 1900s. It notes that while European immigrants entered legally and permanently to find better opportunities, Mexican immigrants often came illegally and temporarily for work, facing challenges like inability to own property and discrimination due to their illegal status and ethnicity. The chapter contrasts the experiences of Mexican and European immigrants during this period.

The vpn
Virtual private networks (VPNs) allow organizations to securely connect to a private network over a shared public infrastructure like the Internet. VPNs work by encrypting data that is sent between devices so that it can only be read by the intended recipient. This creates a secure "tunnel" to transmit data privately across a public network. VPNs provide benefits like extending a private network's reach, improving security, and reducing costs compared to traditional private leased lines. However, VPNs still face security risks such as hacking attacks, weak user authentication, client-side vulnerabilities, and virus/malware infections that could compromise the private network.
Virtual Private Network (VPN).
Virtual private networks (VPNs) allow users to securely access a private network over a public network like the Internet. VPNs use tunneling, encryption, and authentication to provide security. Common VPN protocols include PPTP, L2TP, and IPsec. VPNs allow remote access for users and can connect multiple office sites through site-to-site VPNs. VPNs provide benefits like security, reliability, cost savings, and ability to connect globally but can have lower bandwidth and inconsistent performance compared to dedicated connections.
VIRTUAL PRIVATE NETWORKS BY SAIKIRAN PANJALA
Virtual private networks (VPNs) allow for secure data transmission over public networks like the Internet. VPNs create virtual tunnels between devices to securely transmit encrypted data. There are three main types of VPNs: remote-access VPNs for remote users, intranet-based site-to-site VPNs to connect locations within a company, and extranet-based site-to-site VPNs to connect companies. VPNs use protocols like IPsec and SSL to encrypt data and tunneling protocols to transmit data securely between devices.
Virtual Private Network
Virtual private networks (VPNs) allow users to connect to a private network from a public network like the Internet. VPNs use encryption and other security mechanisms to ensure only authorized users can access the private network and data cannot be intercepted. There are different types of VPNs for both consumers and corporations, with the main ones being IPsec, PPTP, and L2TP protocols. Corporations commonly use VPNs for remote workers to securely access internal networks, while consumers use free VPN services for privacy and accessing censored websites when using public WiFi networks.

Abstract
Virtual Private Networks (VPNs) are beneficial to a company to create secure connections within, and remotely. However, establishing VPN is a complex task that requires making choices on what type of VPN and what VPN technologies to use. There are two types of VPN, but each type serves a different purpose. Further, establishing these types of VPNs require different hardware and software. Therefore, it is important to understand what is required for the type of VPN that one intends to establish. Above all, security is a major concern for VPNs. In addition to enjoying the benefits of VPN companies want to have their connection secure. This means ensuring data confidentiality so that the sent data is seen by the authorized users only. Data integrity defines that the data sent over the network is not altered or tampered with, and authentication entails users of the network to verify their identity. Different protocols provide different aspects of security. In addition, to set up a VPN one should choose the most appropriate protocol that offers the desired security elements. Therefore this paper explores VPN types, hardware and software required for the different types of VPNs and the VPN topologies. The paper starts with an introduction which is followed by a detailed discussion of VPN and the VPN types namely; the remote access VPN and the site to site VPN. VPN technologies continue within the paper and discusses how VPN meets the confidentiality, integrity and availability factors. Under the VPN technologies a more detailed discussion is provided for the IP Sec and GRE tunnelling and SSL VPN.

Secure VPN ConnectionsIntroduction
The world is changing rapidly every day, more so in the technology industry. Businesses are now forced to cope with regional concerns in addition to their local ones. Many businesses are forced to consider the global markets and logistics. These organizations have established branches in different regions of the country or the world. Additionally, these companies need to be secure, fast, connected, and able to communicate effectively.
Until recently, communication between distant branches has been done using leased lines in a Wide Area Network (WAN) form of connection. Leased lines used have ranged from optical carrier-3 which has a speed of 155Mbps or ISDN with a speed of 144Kbps (Comer, 2015). These WAN networks have been advantageous in that the security, performance and reliability resulting in high proficiency. However, setting up and maintaining WAN networks over a large area using leased lines is expensive. Further, leased lines are not viable in terms of mobility .
IRJET- A Survey of Working on Virtual Private Networks
This document provides an overview of virtual private networks (VPNs). It discusses VPN architecture, including remote access VPNs that allow single users to connect from remote locations, and site-to-site VPNs that connect two private networks. The document explains how VPNs work by encrypting data packets and encapsulating them within IP packets to allow transmission over the public internet in a secure manner. Key advantages of VPNs are lower costs compared to leased lines and scalability to connect multiple office locations.
Vpn
A VPN creates a secure connection over a public network like the Internet by using encryption, authentication, and tunneling. It allows remote users to securely access a private network. There are different VPN protocols like PPTP, L2TP, and IPsec that use encryption, encapsulation, and authentication to securely tunnel network traffic over the public Internet. VPNs can be used for remote access VPNs, intranet VPNs between offices, or extranet VPNs for partners and suppliers.

This document provides an overview of virtual private networks (VPNs). It defines a VPN as a private network that uses public telecommunication networks like the Internet instead of leased lines. It discusses the main types of VPNs including remote access, site-to-site intranet, and site-to-site extranet. The document also covers VPN protocols, security features, devices, advantages like reduced costs, and disadvantages like reliance on internet connectivity. It concludes that VPNs provide a secure and cost-effective private networking solution for many companies.
Vpn presentation
Virtual private networks (VPNs) allow users to securely access an organization's intranet from remote locations using public networks like the internet. VPNs use encryption and tunneling protocols to securely transmit data and authenticate users, providing privacy and access similar to a private network. The main benefits of VPNs are reduced costs compared to dedicated private networks, as VPNs can leverage existing broadband internet connections instead of expensive leased lines. Common VPN protocols include PPTP, L2TP, and IPsec, with "tunneling" referring to the encapsulation of packets within other protocol packets to create and maintain virtual connections.

- 1. How Encryption for String Security Works ・ Encryption ・ VPN ・ WAN ・ FIREWALL
- 2. Encryption When you exchange digital data through the network, convert data so that others do not steal a glance while communicating and it is falsified according to set regulatios.
- 3. Virtual Private Network(VPN) Public circuit.. completely.. lease line as if use service. It is used for the connection of the network in the enterprise between bases etc , and the cost is suppressed to the introduction of the lease line.
- 4. WAN Abbreviation of "Wide Area Network". ● The line and the lease line are used. ● The computer is connected mutually.
- 5. FIREWALL I control a particular computer network and communication with the outside, and the fire wall (a fire wall) is hardware equipped with software aimed at maintaining the security of the internal computer network or the software. I compare the cracking act that is going to invade from the outside an internal computer network to a fire and use expression called the fire wall as a thing checking it.
