Network Security in an Encrypted World

If current trends continue, we will probably see encryption's use increase. However, the extensive use of encryption affects current conventional security methods in a very profound way, and this is something the security community must consider. Currently, we rely a great deal on security infrastructure such as proxy firewalls and network-based intrusion detection, tools that rely on being able to inspect the traffic that's passing through the network.. . .

Using OpenLDAP For Authentication

There are few tutorials on how to accomplish using LDAP for authentication, and I found them to be difficult to understand or incomplete, and as a result some research and testing was done to setup LDAP-based authentication on Mandrake Linux. This was done using Mandrake Linux 8.2, and while all supported versions of Mandrake Linux should operate in the same way, your mileage may vary. The information here should be enough to get you started, if not help you finish everything off.. . .

Time to Smarten Up About Security

You'd think we would have learned some important lessons about security when WEP was broken last year by products like AirSnort. Unfortunately, we did not. In fact, some of us believed we could simply take a few security components from the cryptographer's tool box, put them together by the book and wind up with a certifiably secure system. . . .

Telco Security Misses Mark

Searching for relief from the pressures of abundant capacity and intense competition for their core services, carriers such as WorldCom Inc. and Sprint Corp. are rushing headlong into the managed security services business.
