Internet security basics
In this post I will try to give a basic overview about the internet security related issues.
As you may know (or not) your network uses the TCP/IP protocol to communicate. This protocol can be secured with the help of cryptography. The cryptography protocols include SSL and TSL if we talk about web traffic, PGP if we relate to email and IPsec for the network layer security.
I`ll write now about IPsec as this is the protocol suite that secures IP communications with the help of authentication and encryption for each IP packet sent over the network. It is widely used to protect data between multiple hosts, security gateways or between hosts and gateways. There are basic components of the IPsec architecture that are worth mentioning: security protocols (AH and ESP), security for policy management and traffic processing, manual and automatic key management fot the internet key exchange and the algorithms for authentication and encryption.
In the next posts I will tell you more about firewalls, antiviruses, antispyware, email security and much more.
