DoS AND DDoS ATTACK
WHAT ARE THEY?
A DoS attack (Denial-of-Service Attack) is a type of an offensive maneuver that targets computer information systems, infrastructures, computer networks, or personal computer devices in which the perpetrator seeks to make any machine or network resource not available to its meant users by momentarily or indefinitely interrupting services of a host connected to the Internet.
DDoS (Distributed denial of service) attacks are a part of DoS (Denial of Service) attacks. A DDoS attack includes multiple connected online devices, that are together known as a botnet, which are then used to overwhelm a target website with fake traffic.
Difference between DoS and DDoS attacks
The major differences between normal and distributed denial of service assaults are quite substantive. Normally in a DoS attack, a person that is going to attack, uses a single Internet connection to either take advantage of a software vulnerability or flood a target with fake requests that are generally in an attempt to wear out the resources of the server (e.g., RAM and CPU).
Unlike the DoS attacks, DDoS (Distributed Denial of Service) attacks are launched from various connected devices that are distributed across the Internet. These multi person, multi device bombardments are normally harder to avoid, mostly due to the huge number of devices involved. DDoS assaults are more likely to target the network infrastructure in an attempt to saturate it with large volumes of traffic, unlike the single sourced DoS attacks.
How are they a threat to you and your business?
DDoS attacks are now enhancing and are being used as a competitive business tool. Some of the attacks are designed to keep a business competitor from participating in some important event, while some others are designed with a motive of completely shutting down online businesses for months.
The ultimate motive or the idea is to cause interruption that will encourage your customers to flock to the competitor while also causing financial and reputational damage. Attacks that are led by business feuds are often funded quite well and executed by pros who conduct early exploration and use proprietary tools and resources to sustain extremely aggressive and persistent DDoS attacks.
In short, the attacks can cause:
- Disappointed users that may never return
- Data loss
- Loss of revenue
- Compensation of damages
- Lost work hours/productivity
- Reputation damages
How to detect the threat?
Keep observing your traffic to look for flaws, including unexplained spikes and visits from any IP address that is suspicious. All hints could possibly mean attackers performing “dry runs” to check your protection to the attacks before committing to a well planned attack. In order to prepare for such attacks, it is crucial to recognize such hints that might look suspicious.
One more way of possibly detecting an attack is that the server might not completely crash, but the services might get too slow for production. It could take way more time than normal to submit a form or even load a page.
Prevention of a possible DoS and DDoS Attack
- Letting customers to use the site normally as much as possible, even when under attack
- Defending the network from breaches during an attack
- Provide an alternative system to work from
Depending on the possible consequences that would do the most harm to your organization, the chosen solution should offer you one or more of these options:
- Firewall failure
- Service Outage
- Website going down or Customer Complains
