DDoS Believe it or not but DDoS attacks can be very irritating and it can cost you. organizations are constantly under attack, do you have a 24/7 security professionals team to fight the prolonged attack campaigns attackers are deploying, more attack tools and more attack vectors in each attack making the attacks more difficult to detect and mitigate.
Are You Ready to Prevent and Prepare for DDoS Attacks.?
Basically the idea is an attacker recruit an army of bots… a lot of bots to flood the targeted website or network resources unavailable to it’s intended users.
In order to turn a computer into a bot, attackers develop specialized malware, which they spread to as many vulnerable computers as possible. Malware can spread via compromised websites, email attachments, or through an organization’s network.
Many users, tricked into running such malware, will unintentionally turn their computer into a bot and provide an access point for attackers to their computer.
Once a computer turns into a bot, it connects to the attacker’s command and control servers and it begins to accept orders from the centralized machines.
The orders from the command and control servers include directions for launching an attack from the bot’s malware to a particular target using selected attack methods.
An army of bots is named a botnet and usually consist of thousands of bots.
Any time the botnet owners want to launch an attack they send messages to their botnet’s command and control servers with instructions to perform an attack on a particular target. Any infected machines in the botnet will comply by launching a coordinated, well-timed distributed attack known as a DDoS attack.
Launching a large scale DDoS attack is not a difficult task to carry out. DDoS services are available. Anyone using such a service can launch a powerful DDoS attack on a target of their choice for anywhere from $5 to $200 per hour depending on the attack size and duration.
An average duration of a DDoS attack is about 24 hours.
The motivations behind DDoS attacks can be financially driven (pursuit of crippling a business competitor), hacktivism (political), or even just for fun.
No one, however, should doubt the potential cost of a successful attack. The business impact of a DDoS attack is substantial and can involve financial losses, reputational damage, customer agitation, and legal repercussions.
Can you detect and mitigate?
Multi-vector DDoS attacks such as UDP, ICMP and TCP floods are commonly known to consume large bandwidth but today’s application level attacks that don’t consume large bandwidth can easily take down online services.
Can you protect your online services from http flood attacks from DNS attacks from low-and-slow attacks SSL based attacks are hackers favorites because they are easy to launch and very difficult to stop.
Secured online services from SSL based attacks in 15% of DDoS attacks the internet pipe of the customer becomes saturated, can you protect your internet pipe from saturation in 32% of attacks the firewall, the IPS and the ADC become the first network elements to fail
Can you protect your firewall IPS and ADC from a DDoS attack? Can you afford downtime ?how quickly can you detect and mitigate a DDoS attack? how much will a DDoS attack cost you? can you sustain a DDoS attack for over a day, a week, a month? 52 percent of organizations could only fight an attack for a day or less because they are not ready. are you ready?
Arm yourself against DDoS[Prevention]
- Improve Internet and Server Capacity: The main reason your website become unresponsive after a DDOS is because it doesn’t have the capacity to handle the volume of traffic sent by the attacker.
- Use Web Application Firewall(WAF): A firewall is a security system that monitor every incoming and outgoing traffic based on a predefined rules. it can detect and block unusual traffics. it’s a great way to protect a large enterprise-level application.
- Network Defense: Protect your network from DDoS attack by limiting the requests and also dropping all half-open connections.
- DDoS Protection Service: The way this service work is that they route all the traffic through a filter so that only genuine traffic reach your website or application.
- Content Delivery Network(CDN): Using a CDN means that your website is hosted on multiple IP’s; So even an attacker bring down one IP, you still have a few backups that can keep your website running.
- Deploy a Reverse Proxy: A collection of reverse proxy’s can act as a “bouncer” and monitor who is allowed into your network.
- Enable Rate Limiting: When a user surpasses a certain amount of bandwidth you will be notified.
- IP Tables Rules: Write a rule to limit packets and connections per IP, such that, 3 or 5 packets per second and if more than that detected then it has to block that specific IP address and also drop all further connections from that specific IP address.
- Hosting: Choose a host which is reliable and responsive in such situation.
- When such attacks occur, not only your website but all the websites on that server will be affected and most likely they will be down until the issue is sorted. Get in touch with them and ask them if they can migrate your installation to another server.
- Backups: Keep Backups. Both the files and database should have backups.
- Google Project Shield: Project Shield is a free service that Google offers to nonprofit organizations to protect there website from DDoS. The service helps to reduce the traffic request and absorb potential DDoS attacks. To reduce website downtime, it display cashed content to the visitors.
