What is a DDoS attack?
During a DDoS attack, an attacker uses a network of compromised computers called a botnet to send traffic to your network. The traffic overwhelms consumers network resources and makes services unavailable.
For example, you may have trouble accessing the internet or using an application. Common DDoS attacks include ICMP flood, SYN flood, Ping of Death, Slowloris, and more. Each of these service attacks targets different vulnerabilities and must be defended against in different ways.

The best DDoS Protection Tools & Anti-DDoS Software
DDoS prevention software is designed to block malicious traffic from reaching your network. Each solution is different in its approach due to the variety of DDoS attacks you can encounter on a daily basis. Let’s have a look at some of the best DDoS Protection tools as well as Anti-DDoS software available.
AppTrana is a fully managed WAF, DDOS and Bot mitigation solution from Indusface. The edge service bundle includes a Web Application Firewall, vulnerability scanners, a patching service, and DDoS protection. The service can absorb extreme volumetric attacks and is able to distinguish DDoS from genuine surges in traffic.
AppTrana uses its database to develop rules and alert conditions for your websites. Sites are monitored 24×7 to make sure no attack spills through the net. The software can also automatically detect botnets based on their behavior and block them. This means that the botnet cannot disrupt your site. To keep the network protected from layer 3 attacks, AppTrana has been built on AWS to help resist common volumetric attacks.
The vulnerability scanning service in AppTrana references the OWASP Top 10 Threats and the SANS 25 Vulnerability list. The service immediately fixes any vulnerabilities that it discovers through patching. Vulnerability scans are conducted regularly and automatically. Other features in the AppTrana bundle include SSL offloading and a content delivery network for site acceleration.
There are two editions of AppTrana: Advance and Premium. The Advance service is the edge system described above. It costs $99 per protected app per month. The Premium version is a managed website security service. This includes the services of network security analysts to identify attacks and adapt security protection strategies. While vulnerability testing is included in this plan, those checks are supplemented by human pen testers. The Premium plan costs $399 per protected app per month.
AppTrana Advance edition is available for a 14-day free trial.

DDoS Protection FAQs
Do VPNs protect you from DDoS attacks?
Yes. A VPN will protect you against DDoS attacks in two ways. First, it hides the real address of your device – all traffic goes to the VPN rather than directly to you. Secondly, the VPN has a great deal of connection capacity and so is able to absorb the volumes of traffic that would overwhelm your computer. Get a VPN service with a static IP address if you expect incoming connections.
How long can a DDoS attack last?
Commercial DDoS services offer attack durations for as little as 5 minutes. Hardcore hacker-team DDoS attacks can last 24 hours or even as long as 72 hours.
How long does it take to recover from a DDoS attack?
DDoS attacks don’t cause any physical damage, they just block legitimate users from getting access to your site or service. Technical recovery is immediate because as soon as the fake connection requests stop, legitimate requests will get through. Reputation damage can take a long time to recover from.
Can you reverse a DDoS?
In theory, you can DDoS back to an address that DDoSed you. However, there isn’t much point in doing that because the computer that attacked you is just infected by a bot. You won’t get to the real attacker. Also, a botnet that runs an attack can contain hundreds of thousands of computers so you would tie up your own resources for a long time in revenge attacks on all of them.
