A VPN allows remote users to securely access a private network by establishing an encrypted connection over the public internet. There are three main types of VPNs: client access, intranet, and extranet. Security risks include attacks on the transmission line or stealing certificates and keys. To use a VPN, one needs OpenVPN software along with client and server certificates and a password. Additional security measures in OpenVPN include TLS encryption, larger RSA keys, larger symmetric keys, and hardening against DoS attacks and port scanning.

Firewallpresentation 100826052003-phpapp02(1)
A firewall is a device or software that protects private networks from unauthorized access. Hardware firewalls protect entire networks at the router level while software firewalls protect individual computers. There are three main types of firewalls: packet filtering routers inspect packets and allow or block them, application-level gateways act as proxies for applications, and circuit-level gateways set up two TCP connections to determine which connections are allowed. A firewall establishes rules to allow trusted traffic to flow automatically while blocking dangerous traffic to protect computers and networks.

Http tunneling exploit daniel adenew web
HTTP tunneling encapsulates other network protocols within HTTP requests to allow communication through firewalls that normally block other protocols. It works by opening an HTTP connection between an application and mediator server, which relays communications between the application and remote host by wrapping the actual data in HTTP requests and unwrapping it. The httptunnel exploit uses this by installing client and server components that establish a telnet connection tunnelled over HTTP, allowing attackers to issue commands to the victim despite firewall blocking of telnet. It is difficult to detect as it mimics normal HTTP traffic patterns. Administrators are advised to patch systems, disable unnecessary services, review firewall logs for unusual patterns, and monitor for abnormal HTTP requests.

Virtual Private Network- VPN
This document provides an introduction to virtual private networks (VPNs). It defines the key terms "virtual," "private," and "network" that make up a VPN. The document outlines basic VPN requirements like user authentication, address management, data encryption, and key management. It describes the main types of VPNs: remote access, intranet, and extranet. Remote access VPNs allow mobile users to connect to an organization's network. Intranet VPNs connect organization offices over the internet. Extranet VPNs are similar but connect external users like customers or suppliers. The document also discusses tunneling, which encapsulates data packets for transmission, and lists some advantages and disadvantages of using VPNs.
Wifi Security
Wi-Fi is a wireless networking technology that uses the 802.11 standard developed by IEEE to allow for wireless local area network computer communication in public spectrum bands. Securing wireless networks is important and can be done by securing all wireless devices and educating users, actively monitoring the network for weaknesses, and using stronger security protocols like WPA2 instead of the deprecated WEP. While SSL encryption provides some security, public Wi-Fi connections can still be intercepted using man-in-the-middle attacks, so using a VPN service or SSH tunneling can further improve security when connecting over unknown networks.
Firewall traversals
This document discusses firewalls and firewall traversals. It begins by introducing firewalls and their purpose of securing networks while restricting harmful traffic. It then discusses various methods of traversing firewalls, including SSL/TLS tunneling and proxies. SSL/TLS tunneling involves creating an encrypted tunnel between a client and server through a proxy, while SSL proxies terminate encryption and recreate certificates to provide visibility of encrypted traffic. The document covers the workings and benefits of SSL proxies, as well as types of firewalls and issues they can present.
Fire wall security
This document discusses different types of firewalls including packet filtering firewalls, application gateways, circuit gateways, and dynamic packet filters. It describes how each works and their advantages and disadvantages. Packet filtering firewalls use transport layer information to filter packets and are the simplest but least secure. Application gateways use proxies to filter at the application level for specific protocols like HTTP, FTP, and SMTP. Circuit gateways filter at the TCP level. A dynamic packet filter combines these approaches. The document also discusses firewall configuration and limitations, such as not protecting against inside threats.

VPNs offer security benefits but can be difficult to configure and require high-speed internet connections.
Vpn ppt
Virtual Private Networks (VPN) allow secure connections over public networks like the Internet. VPNs use encryption to create "virtual private tunnels" between devices. This allows remote users to access resources on a private network as if they were directly connected. There are two main types - remote access VPNs for individual users and site-to-site VPNs to connect multiple office locations. VPNs work by encapsulating data packets within encrypted "tunnels" to securely transmit them between endpoints across public networks while maintaining privacy and security.
Vpn-Virtual Private Network
A VPN, or virtual private network, allows users to securely connect to another network over the internet. It encrypts data being sent and received to protect it from being accessed by unauthorized parties on public networks. There are different types of VPNs for various uses, such as intranet VPNs that connect corporate offices, extranet VPNs that connect partners/suppliers, and remote access VPNs that allow individual users to securely access a remote network from anywhere. VPNs provide benefits like security, mobility, and reduced communication costs compared to traditional private networks.
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.
