Introduction to network
Introduction to networkDhani Ahmad Networks connect two or more computers using various mediums like cables or wireless signals. They allow for sharing of files, data, and applications between systems without needing to physically transfer anything. Networks can be configured in a client-server model where some computers act as servers providing resources and other computers act as clients accessing those resources. Alternatively, networks can use a peer-to-peer model where each computer both acts as a client and server, allowing all systems to share directly. Networks can operate within a single location or span multiple geographic areas. Hardware like network interface cards and cables form the physical infrastructure while networking software manages communication and resource sharing.
Data security in local network using distributed firewall ppt 
Data security in local network using distributed firewall ppt Sabreen Irfana Distributed firewalls provide data security in LANs by enforcing security policies at network endpoints rather than a single centralized firewall. This overcomes issues with traditional firewalls like single points of failure, restricted topologies, and an assumption that inside users are trusted. A distributed firewall uses a central management system to define security policies which are then enforced by policy agents on endpoints using public key certificates for authentication. This allows filtering of both internal and external traffic according to the security policy.

Root via sms. 4G security assessment 
Root via sms. 4G security assessment Sergey Gordeychik Having developed a test set, we started to research how safe it is for clients to use 4G networks of the telecommunication companies. During the research we have tested SIM-cards, 4G USB modems, radio components, IP access network. First of all we looked for the vulnerabilities that could be exploited remotely, via IP or radio network.
And the result was not late in arriving. In some cases we managed to attack SIM-cards and install a malicious Java applet there, we were able to update remotely USB modem firmware, to change password on a selfcare portal via SMS and even to get access to the internal technological network of a carrier.
Further attack evolution helped to understand how it is possible to use a simple SMS as an exploit that is able not only to compromise a USB modem and all the communications that go through it, but also to install bootkit on a box, that this modem is connected to.

VPN - Virtual Private Network
VPN - Virtual Private NetworkPeter R. Egli Overview of VPN protocols.
VPNs (Virtual Private Networks) are often viewed from the perspective of security with the goal of providing authentication and confidentiality.
However, the primary purpose of VPNs is to connect 2 topologically separated private networks over a public network (typically the Internet).
VPNs basically hook a network logically into another network so that both appear as one private local network.
Security is a possible add-on to VPNs. In many cases it makes perfectly sense to secure the VPNs communication over the unsecure public network.
VPN protocols typically employ a tunnel where data packets of the local network are encapsulated in an outer protocol for transmission over the public network.
The most important VPN protocols are IPSec, PPTP and L2TP. In recent years SSL/TLS based VPNs such as OpenVPN have gained widespread adoption.
