Let's say my site was getting DDOS'd. Let's say I suspected I knew the attacker's home IP address. Would there be anything I could do with this information to either end the attacks or penalize the attacker?

I have a VPS that's on the awknet network and I'm receiving DNS DDoS and I don't think they have anything to stop these attacks, how can I prevent these?
View 4 Replies View Relatedone of my costumers server is getting ddos attacks. I solved syn and get attacks with litespeed web server but I have another problem. They started to do udp flood. I m losing connection to my server. I bought new server with 1 gbit port for solving it.

But as mentioned, a lot of attacks can be stopped simply by proper tuning of your IP stack and some simple firewall rules.
My question is as a new Dedicated Server Owner what tuning and rules do I need to implement in order to protect me from these "small scale DDoS Attacks"?
I do not run a DDoS prone site(i hope not lol) but I want to secure myself as much as possible and have a headache free run other than the headaches I cause myself of course.
I want to understand the mechanics of a DDOS attack. I have been doing a lot of reading about them this weekend.
The way I am understanding it, a DDOS attack is done at the network level. It may be requesting that pages from a given website, or websites, are served up, but it basically will effect the entire network. So if 'page display' requests are made to a website(s) that is hosted at ABC Hosting (example only), to the tune of 15GBs then I have to assume that the network will be terribly degraded. If that is so, wouldn't other servers also get taken out?
I believe the architecture of the internet is something like this (example only):
Gnax --> Planet, SoftLayer, RackSpace, etc.. --> Reseller --> Smaller Reseller --> Me
If that is true, is each level along that route using their own networking system or are they all dependent on ones that major Data Center uses?
My current site has been taken offline since it was being ddos attacked, been with my current hosters for 3years at least, but with recent events they gave me the option to shift my site to a dedicated server or me to move of bascially. (impression I get now, since they seem to be taking longer to reply to my messages) I was being ddos attacked since I refused to give a copy of me software to the visitor at my forums/site.
ive been looking round site after site and I cant make up my mind who to shift too, also if that same idiot who ddos attacked me does it again before I can take any action, I would be in the same situation again.
I have multiple domains and all my sites in total are about 5gig in size, cpu usage is avergae and queries roughly about 15/17 the most, I currently pay £130.00 a yr
I have had few bad experiences with hosting companies but learnt along the way, and assumed my current hosters would be a reliable place to stay at. My sites been offline since friday and I would like to get it back up again asap. Last thing I want to do is rush into a hosting package and be stuck in a dud situation.
I would also like to take action upon the person who has been ddos attacking me, I managed to get hold of his details and I also have confirmation that they are correct, what can be done legally?
My sites are getting heavy DDoS attacks.
What's the best firewall? I'm currently using ACH software firewall but the attacks are getting so bad my site's are going down (apache is shutting down/locking) and sometimes my server even crashes.
Anyone recommend a better software firewall or a really cheap but good hardware firewall?
Could my host just use a router or something as the firewall or would that not do? I'm looking for something really affordable as a solution.
Some of my websites have been under a DDOS attack for about a month now. Is there any way I can find who is behind this attack and what their motive is?
How much does it cost to launch a DDOS attack and how long do they usually last?
i have a shared host
my site under ddos attacks!
i want to upgrade to Dedicated Server
i needed to Dedicated Server contains DDOS protection!
btw: Site visitors 2500 in day!
how to prevent my web servers from DoS attacks?
View 12 Replies View RelatedI know there is no device can protect you from ddos attacks, but I wonder which one is the best to help you reduce the attacks? It might be intelligent to "feel" the attacks? Brand names from Cisco, Foundry, Nokia...?
View 2 Replies View RelatedAs many of you already know, not everyone has the money to spend on physical firewalls, for example a cisco firewall. I would like if everyone could share little tips and tricks towards securing a server they learned over time. Nothing in big detail. I thought if we all share our ideas, it would help quite alot of other people. For example, here is a good layout I believe. Please note this is towards a game server setup.
Shorewall Firewall - Block Unneeded Ports + Block Ping
Apache Web server - Installed with "mod_security"
SSH-Faker - Stop thoes bots from trying to gain access to SSH (Guessing Passwords)
DDoS Deflate - For me, does not really work. (I know, mainly for port 80 so webhosting) But still have it installed.
Bash Scripts Monitoring # of connections per ip with Netstat.
PSad - Monitoring and Reporting Port Scans (Optional automatic timed block)
VNStat - Monitor Current/Monthly/Yearly Bandwidth (Does not hog resources)
I'm guarenteed to of left alot out than just the above. If some of you could also share some simple things you do for securing a server, would be great.
Hosting providers and DDoS attacks!
Hello guys! I am looking for a reliable hosting provider! I mean the most important thing for me know is to be sure that my future hosting company will manage to protect my websites against DDoS attacks fully! What hosting company according to your opinion can be considered as the most stable hosting solution against DDoS attacs?
How does Hivelocity deal with DDos Attacks?
Do they have any similar protection to ThePlanet or Softlayer?
I believe that my site is being DDoSed against, and I'm wondering how I can prevent this from happening.
I'm running CentOS 5.3.
Are there any server side scripts of PHP scripts that could be used to dynamically block out IP's that are consuming too many resources on the VPS?
Can you restart the httpd to get the server online again while you are under an DDoS attack?
The reason for asking is that I was told that when restarting the httpd it should start to work again instantly, and so it seems.
But why? doesnt the attack "continue" after the restart?
My host tells me that they have security to stop DDoS attacks and stuff, however today my server load jumped to 17.12 and my site went down giving me a "Network Timeout" error.
My host tells me it's my fault that I am using too many resources. The MOST my site has been on load is 3.06 and that was around lunch time a few weeks back. It's 11:43 and the server load is 17.12? I think my host is pulling my leg. I have not added ANYTHING new to my site and have not changed anything in 3 days. The load has been fine till today.
I use In Motion Hosting.
I am about to get dedicated server with Gigenet.com.
Is this company good as they say they are?
How stable is it?
Can they really handle multi gig DDOS attacks?
One of the sites I run is a forum with a political component, and 4-5 times over the last week we've been seeing DoS attacks. They're not terribly sophisticated -- generally 1-3 compromised servers throwing packets my way -- but they're enough to clog my pipes and take my sites down.
What I'd like to do is put a new server up at a data center that's D(D)oS aware that can hopefully respond to these attacks automatically. My current provider has been giving solid support, but the best they can do is null route the affected IP, rather than filtering the incoming attack.
Can y'all name a few providers I should look into? Right now I'm just looking to move 1 box (or maybe a box and a firewall depending on the setup).
Can someone please recommend a hosting company that offers 24 hours toll free phone support with very good DDOS protection services?
Our server has been attacked for the past couple weeks and current host can just null route the IP being attacked but cannot offer anything beyond that...which does not help us. We are talking about large 3 GBPS attacks.
to day i log my site and see notice :

How To hinder other's attacker?
i have VPS CentOs5 running 2.6.9-023stab044.11-entnosplit with Plesk 8.3 Panel ..
last nigth when i was talking with the support center and i past my root passwd ..
after 10-15 mnts some attacker has change my page (index.html)
the server is new .. i just take VPS server before 3 days .. so there is no way to upload or run any php script ( worm ) in my server kz i didn't install anything there else (.html) pages ..
so i stop my VPS tell today and now i change my password and run the command to find any php files in my Vhosts folder wich content my sites directory...
i didn't find anything there and everything looking as a Defualt..
now the question is there anyway for the attacker to hack NixCore V1.5.0 Support Center ...?
and if there any way to check my server if there any uploading new files? whatever is .php ; .pl ; .rar ; .gif ; etc ...
and what command to show what the user group have the root permission?
I have to deal with a lot of dictionary attacks. One evening, I got fed up with them and decided to do something about it. So, I wrote a service in VB.NET that monitors the Windows event log. I check for too many incorrect login attempts to MS SQL.
If I find someone attempting to dictionary attack, Windows shows the IP address of the invalid login attempt in the event log. So, I parse the event message, grab the IP address, and use IPSec to block the would-be intruder. Excellent!
Ok. That takes care of SQL attackers. But, what about RDC (Remote Desktops or Terminal Services) attackers? I started using 2x's SecureRDP. It works great, but the logging feature is broken. It doesn't accurately log the attackers' IP addresses. So, how can I get the IP address of those attempting to login via RDC? Anyone know? There has to be a way.
Has anyone used Attacker.net for server admin work, especially on FreeBSD? My other Admin team bailed on me, so I am looking for a new team to Secure and Harden my box. I have searched the boards, and have not found a review on them yet.
View 7 Replies View Relatedit's come under my attention that dragonara.net has been ddosing me today since morning from the ip:
194.8.75.229
What's so ironic about it is that the ip is from a UK DDOS protection site so i'm expecting some email with their services in the next hour or so. Stay clear of them they are fakes and e-terrorists.
I'm getting DoS attacks on my new dedicated server and I've had about 600 emails from my server about IP bannings. I can't even access my server via WHM at all at the moment! The sites are still online and the server is up but I can't log into WHM. What can I do to remedy this?
Also I can't quite understand why anyone would conduct a DoS attack in the first place...
I seem to be getting a lot of mail attacks to accounts located on the server. However, most of the email addresses do not exist and therefore the emails are bouncing back and getting stuck in my mail queue manager. There are something like 20 emails per minute getting stacked up in there and it is causing a massive load on the server.
How can I stop these attacks?
my webserver defaced with this persons name all over my site.
I was reading and it said JaMaYcKa does this things through a cPanel bug.
Apparently our entire host has been hacked too. I'm very dissapointed as I was on the verge of starting one of my most biggest projects and now it's gone. :'(
Recently, i hosted my domain with two different servers. but both of them were attacked by malwares and viruses. Google also started showing warning like "This site may harm your computer".
Now i can't open my site on firefox (it gives security warning)... when i open in explorer , my index page is totally changed.
Is there a solution for that? Which linux server will be best to protect my site from malware attacks.
I can see lot of MSSQL Server attacks. In event viewer "Login failed for user 'sa'. [CLIENT: Some IP]"
Most of the attack coming from Chaina. Tipically what I'm doing manually is get that entire IP range and block from Windows Firewall level.
Now I have plenty of blocked IP ranges all over the world.
What would be the best way to avoid from those kind of attacks ?
my VPS provider just rebuilt my VPS after many hack attacks.
From some days I am getting emails from firewall that someone login to my VPS/mySQL using SSH.
I don't know what they do, but they don't disturb any account. Only some downtime feel during this. But last night my VPS stop working so my provider rebuilt VPS.
how I can secure my VPS now. I have Cpanel installed.
