Do not trust any security related answers you see on StackOverflow/Security.StackExchange. Not from me, not from anyone. There are very smart people on SO/SE and there are excellent answers given, although the right answer is almost never chosen. Test everything, trust no one.
I have been writing exploit code for a while. There is no perfect system, vulnerable code will always exist.

Why can we not block DNS Amplification attack by blocking UDP packets or DNS response packet? @Steel City Hacker Cloudflare has had problems with neighboring nodes becoming initiated with traffic. However, this does not change the solution. CERT suggests restricting DNS clients to 5 resolutions per second... that times 27 million hosts is still a massive amount of traffic. A real solution is to segregate the internet, HTTP servers do not need UDP traffic routed to them. In the highly unlikely event of a Neighbor node to your Amazon EC2 host goes down, then that is their problem, they should consider segregation. |

How to prevent restrict access to a web application to authorized devices only? Will never be possible! This question has been asked over 9,000 times, and everyone who asks it doesn't understand even the most basic concepts of security. |

What can be used to keep xp_CmdShell in SQL Server disabled? luckily there isn't down-votes for comments, but seriously now, why would they allow shell access from SQL injection? Seriously, why? Oah Microsoft, why do you eat the glue? |
