Network Security Protocols

We can’t imagine internet without network security protocols in a world where the need for privacy and data confidentiality with efficient authentication systems is very increased. Who would give his credit card without ssl protection?

In this context IT infrastructure must be managed with a security approach to protect from modern threats of hackers with very high skills. Why don’t use DNSEC? Why use DNS resolver? How to defense from DDOS and DOS attack? How to monitor attack and web site performance? How to configure a reverse proxy in security?

The mission of this site is to give to internet comunity (I hope at least to young system and network administrators) my knowdlege and experience in IT security management.
