Security involves the authorization, authentication and privacy and it can be achieved by implementing a security solution in your network.
A network is susceptible by various internal and external threats such as viruses, Trojans, spyware, adware, hackers and physical security threats. The insecure and unmanaged communication may results into the loss of data, identity theft and the loss of the private information. The following techniques should be implemented to make your communications secure.
Access Control
Controlling and authorizing the access to the network resources is another way to secure your network. You can permit or deny any user or group of users based on your pre-defined criteria. Access control technique is used to maintain the physical resources of an organization.
Cryptography
Cryptography is a security technique that is used to convert the data into unreadable form. It involves the encryption and decryption of the data. Cryptography can be classified into the Symmetric key system and the public key system. By using the cryptography, your transmitted information is encrypted and the destined recipient must have the key to decrypt the information in order to read it.
Antivirus
Antivirus is the most important security solution for a single computer to a big network. Every online computer is susceptible to viruses and spyware so there should be properly configured antivirus software that can deal with the viruses. There are many vendors that provide the antivirus solutions such as Symantec, McAfee, Panda and Trend Micro. You need to install an updated antivirus and regularly scan your network computers with it.
SSL
SSL stands for secure socket layer and it is a security mechanism that is used between the client/server communications. It is a standardized security technology that is used to establish the secure link between the web browser and web server.
Authorization
Authorization is a security technique that is used to authorize the users. It involves the use of passwords and other security protocols that allow the access to the network users only to the authorized users.
Filtering
Filtering is the technique that is used to block the unwanted contents and traffic on a network and internet. There are different filtering techniques and technologies that can be used secure your network.
IPSec
IPSec stands for Internet Protocol Security and it ensures the secure communications over the IP networks. IPSec was developed by IETF and it has been widely used in the VPNs. The sending and receiving network devices must have a public key to exchange and information. IPSec uses two encryption techniques i.e. Transport and Tunnel.
