What is the Dos Protection Method?
DDoS can bring down your website or even your entire network, so it is a prime target for many companies looking for the best DDoS defense method. As a DDoS attacker, you want to maximize your chance of attacking a server that will bring down your website, right? Well... It's complicated! First, there are multiple mitigation methods for every possible attack. While every method has pros and cons, some methods are not always available, so it is important for you to understand each method and weigh your mitigation options.
Commonly used by: Bandwidth control tools such as FreeDDoS or ICAST software are often used by DDoS attack mitigation tools. These tools analyze and adjust packet filtering and rate-limiting for optimal results during an attack. Some common tools include FreeDDoS, Epping, and others. Most ITSPs have the ability to block or modify ports based on user authorization. In addition to being able to block or modify traffic, many IP phones also feature do-not-forward policies, which prevent calls from going to a known attacker or server.
Popular DoS protection services include Webroot and ZoneAlarm. Webroot offers several commercial products including Webroot Insulation. ZoneAlarm offers several commercial products as well including Flood Protection for Small Online enterprises, Data Center Preservation and Data Center Reliability, EAP Testing for Your Business and Enterprise Application Performance, Real Time Protection for Large Applications and High Availability. If you have applied for a Small Business Internet Service (SBSI) or other service plan and are concerned about security, then these companies can help you! Webroot can provide support for both the desktop and server applications.
Common types of threats in today's world are: directory attacks, spam, viruses, phishing, spoofing, and more. A good way to protect yourself against most of these is to enforce smart access rules. Smart access rules are like policy rules that dictate how users gain access to a file. For instance, a file containing a virus should be inaccessible to anyone except those who have been granted permission by the user. The file itself should be checked for viruses before it is opened. If a virus is found, the user would be asked to either cancel the action or find another location to download the file.
Many companies that offer commercial firewall programs often recommend using the "traditional" for protection method. This has the advantages of allowing IT personnel to familiarize themselves with the system and implement custom settings if necessary. However, it is recommended that companies switch to a rate-based protection in order to protect against network attacks that utilize scripts that run at different levels of priority. These scripts would be denied in a rate-based protection mode.
One example is when a scripting agent is trying to access a web page that should only be accessed from an authenticated user. When this web page is accessed, the scripts will receive an ICMP Echo Request message that contains an IP packet with the header of an ICMP Echo Reply. If the script then proceeds to execute the requested packet, it will cause the ICMP Echo Request message to be returned. The ICMP Echo Reply will contain a suspicious control flow detection packet that has the destination port set to an incorrect port. The packet will be sent to the user's destination port and will cause the packet filter to generate a reply that is matching the ICMP Echo Reply.
Rate-based scanning detects and removes these attacks from your network. The software works by performing a quick scan of the system and reports any irregularities it discovers. It can be configured to perform a full or detailed scan. This allows you to fine-tune the protection settings to prevent or stop the most common Dos attacks.
A detailed scan will identify not only the target program but also the method by which it has been installed. It will report any malicious programs or scripts that have been found on the system and will list the ports under attack. If multiple programs are being attacked, the software provides a list of all of the processes that have been infected and will allow you to isolate and remove them. With a comprehensive scan, you can easily disable or protect against the most common forms of malware and Ddos attacks.
