I would install the Star topology which is the most common type of network topology that is used in offices. Star topology is the best since each node is connected by more than one link basically two connection to reach a node. The speed of most star configurations is hundred megabits of data per second with gigabit hub or switches and NIC cards speeds can be at one thousand megabits per second. In a star topology is possible to have all the important data back ups on the hub in a private folder…

importance of prioritizing the continued security of the power grid should be at the top of the list. There are many different options that can improve security levels of both a physical and logical nature, such as disk drive encryption, digital certificates, Transport Layer Security (TLS), and Virtual Private Networks. Recommendation: Implement Full Disk Encryption Full disk encryption is the ability to convert data into unreadable code that can only be deciphered by authorized people. The…

from a mixture of dangers. You require various layers of security. On the off chance that one comes up short, despite everything others stand. System security is proficient through equipment and programming. The product must be always redesigned and figured out how to shield you from rising dangers. A system security framework as a rule comprises of numerous segments. In a perfect world, all parts cooperate, which minimizes upkeep and enhances security. System security segments regularly…

Configure a VPN Connection in Windows 8.1 A VPN is one common method of extending a private network across the Internet and gain access to network resources from a remote location in a secure manner. A virtual private network (VPN) is a private network that uses public telecommunications infrastructure, usually the Internet, to connect to a private network, such as a company's internal network infrastructure. A VPN remains private by using a secure tunneling protocol and other security…

Any benefits happening by connecting to internet will occur with losing control over our confidential data. In HealthCare Industry, Data is very sensitive, even when you connect to home network, exposes…

VPN A virtual private network is used by organisations to help secure data on a network. It’s very hard to access these private networks meaning that the data becomes much more secure and it can be used across a large area of a network, including many computers. This isn’t an expensive thing to do anyone can do it by using simple publicly available infrastructures. VPN also makes use of encryption firewalls and authentications services when sending data across the web. This data is protected by…

What is a VPN? It stands for virtual private network. Its main purpose is to secure the connections between the host and the server. It fulfills that purpose by using tunneling protocols, encryption, data encapsulation and certified connections to protect the identity of the host. The simplest way to think about it is to compare it to a LAN connection but without wiring. The History of VPN: Early VPNs were often set up to give individual employees secure remote access to their company…

IPsec is often installed on today's IPv4 networks to protect communication over VPN networks. It is used to access VPN, as well as between VPNs. IPv6 transition mechanisms can use this kind of infrastructure to achieve a certain level of protection, even in the absence of IPv6 IPsec. Remote IPv4 hosts access private networks by establishing encrypted VPN access to a gateway device set up for this purpose. If the same host is capable of IPv6, it can break through an IPv6 tunnel over this…
