Post date: November 25, 2005, 21:11 Category: Security Views: 3761 Comments
Tutorial quote: Is your server as secure as it could be? Sure, you use a firewall, mandate strong passwords, and patch regularly. You even take a proactive approach by performing security audits with tools such as nmap and Nessus. Yet you may still be vulnerable to zero-day exploits and privilege escalation attacks. If these possibilities keep you awake at night, you're not alone. The sleepless folks with the grsecurity project have developed an easy-to-use set of security enhancements to help put your fears to rest.

Building an LDAP Server on Linux, Part 1

Post date: April 15, 2005, 17:04 Category: Network Views: 3321 Comments
Tutorial quote: Your network is growing in size and complexity. It's taking on a life of its own, spreading and growing and absorbing everything in its path. You're tearing your hair out trying to keep track, and your users have somehow discovered your secret phone number and are pestering you with endless questions and demands--where do I find this; I don't want to keep track of a dozen different passwords; nothing works like it should.

Of several possible solutions, consider two: 1) find a new hiding place, or 2) implement an LDAP server. While finding a new hiding place might sound ideal, it's an option we're going to have to save for a future article. This series will instead explain what LDAP is good for, detail how to build an LDAP server, and cover what you can do with it.
