-===== Intrusion Detection System ===== 
  
-==== What does an IDS do? ==== 
- 
-An Intrusion Detection System monitors a network, detecting malicious activity and blocking the bad attempts for a fixed period of time. 
- 
-==== How much does this cost? Who built the platform? ==== 
- 
-Our IDS platform is included at no additional cost and protects our locations as a whole. 
- 
-The platform itself was built in-house over the years.  
- 
-==== What does it protect against? ==== 
- 
-The current revision of our platform best effort monitors for the following network wide activities: 
- 
-^ The 'naughty' list ^^^ 
-^ Activity ^ Port ^ Note ^ 
-^ Daemons, etc ^^^ 
-| SSH account brute forcing | 22 | Common. 20+ blocks a day | 
-| FTP account brute forcing | 21 | Not very common. 1 - 5 blocks a day | 
-| NetBIOS exploits (Windows) | 445 | "God dammit Gates!". 250+ a day | 
-| Mail Server brute forces | 25, 110 | Fairly common. 5+ a day | 
-^ Abused protocols ^^^ 
-| NTP Amplification | 123 | Extremely common | 
-| DNS Amplification | 53 | Extremely common | 
- 
-Remember, this is is a best effort platform. Our IDS does not monitor for directed attacks (read: someone decides they want to brute you directly). We always recommend you change your SSH port when possible and **always** keep your applications up-to-date. 
-==== Can I be excluded from the IDS? ====  
- 
-No. 
- 
-Previously we used to allow users to opt-out but after countless people getting compromised after requesting such, we've revised this policy. 
-==== Does the IDS protect from bot spam? ==== 
- 
-Kind of. As of right now our IDS monitors for HTTP connections which will stop some bot spam. 
- 
-We're currently considering importing [[http://stopforumspam.com|stopformspam.com]]'s blacklist into our IDS platform. If you wish to voice your opinion/concerns about this, just email [[admin@frantech.ca|admin@frantech.ca]] or [[https://my.frantech.ca/|log a ticket]]. 
- 
-==== Does this IDS sniff my traffic? ==== 
- 
-For the most part, **no**. 
- 
-Our IDS works off of a cluster of traps setup throughout our deployments. When one of them is tripped 
-by exploit scanners, the offending IP is nullrouted for a set amount of time. 
- 
-For NTP & DNS amplification, we monitor for specific packets at the node side and block them 
-before they ever get to your virtual server. 
- 
-We've publicly discussed, and shared, how we handle NTP amplification at [[https://vpsboard.com/topic/3564-howto-stop-ntp-amplification-attacks-from-reaching-your-nodes/]].
