Little obscurity in Security might actually be a good thing

I kind of agree as long as 

• It is an additional layer
• One does not rely on the obscurity factor fully
• the cost benefit ration is in favor of Obscurity

According to the article:-

Supplementary defenses include

1. Changing a server’s default port 
2. Server header masquerading
3. Use non-standard naming conventions
