(DDOS) distributed denial-of-service mitigation is the process of protecting targeted networks and servers from attacks. A protection service based on the cloud mitigates the threat by protecting the intended victim. This is a type of cyber attack specifically targeting the most critical systems of the business to disrupt the connectivity or the network service. The result is the user is denied service from necessary resources. The attack combines the power of numerous computers infected with malware with the objective of targeting one system.
The Types of Attacks
There are three key types of attacks. The first is called a volumetric attack. This is when false data requests overwhelm the bandwidth of the network on every single open port available on the device. Once the system has been flooded with malicious requests, the data must be constantly checked. This means legitimate traffic cannot be accepted because there is no room left in the system. The two most frequently used volumetric attacks are ICMP and UDP floods.
The protocol attack damages the connection tables responsible for verifying the connections. This involves sending malformed pings, partial packets and slow pings. This can overload or crash the system because it creates memory buffers. Firewalls are unable to prevent this attack because it has the ability to target the firewalls.
The application layer is in the closest contact with the interaction of the users. An application layer attack is concentrated on the layer responsible for direct traffic from the internet. The potential attacks focus on HTTPS, HTTP, SMTP and DNS. This type of attack makes it difficult to catch the perpetrator due to the smaller amount of machines being used. This means it is possible to trick the server into believing the attack is nothing more than a high traffic volume.
The Importance of Mitigation
A mitigation plan can prevent attacks by making a complete security assessment. This is simpler for smaller businesses because larger companies often have multiple teams and an extremely complex infrastructure. Once the attack has occurred, the time for planning has already been lost. It is critical to ensure prompt reactions to mitigate the possibility of an attack. The first step is the development of a defense strategy. The strategy defines the impact of a malicious attack. The employees must understand their responsibilities and the data center must be ready to execute the plan. This can save the business from the time and expense of a lengthy recovery period while minimizing the chances of a successful attack.
The Most Important Elements of Mitigation
Every company needs to have mitigation in place. This provides the systems with filtering tools, advanced detection of potential threats and protection through software and hardware. Every company needs a response team to make certain the reaction to an attack is efficient, fast and organized. All procedures should be assigned to individual teams. This enables the employees to know where to turn if there is an attack. A complete list of emergency contacts should be posted along with the correct procedures. There must be solid communication between the company, their clients, their security vendors and their provider for cloud services.
Preventing Attacks through Security
The best possible way to prevent attacks is to decrease user mistakes as much as possible. This requires strong security practices. The employees should be required to change their passwords fairly frequently. Secure firewalls and anti-fishing will restrict most outside traffic. This is the basis for good security setup. Multi-level strategies are critical for ensuring the network remains secure. This includes the combination of numerous management and prevention systems including firewalls, a virtual private network (VPN), load balancing, defense techniques and content filtering. This is the best way to locate potential inconsistencies in traffic often resulting in an attack. High quality security can successfully block the attack.
Unfortunately, the majority of standard equipment currently available on the market offers very few options for mitigation. The best recourse is outsourcing to obtain the best possible mitigation available. Many of these resources are cloud based and simple to obtain. This is the ideal solution for both small and medium businesses because they can remain within their budget for security. Mitigation also means having multiple servers. This will provide additional resources if there is an attack on one of the servers. Outsourcing the service will enable the business to further increase security by having their servers in different locations. This makes it a lot harder for the attacker to target the business.
Updating the Systems
When any system is not kept updated, it is at a higher risk for an attack. Mitigation ensures the newest versions of software are installed to tighten the security and decrease the access for potential attacks. The main reason mitigation is so critical is because the attacks are extremely complicated. The system must be able to identify any traffic anomalies immediately to provide the necessary response. When the infrastructure has been properly secured, the threat is automatically minimized. This protects the business from all different types of attacks.
Identifying Unusual Activity
The best way to prevent any attack is with early detection. There are all different types of attacks but there are commonalities. The most common signs there has been an intrusion into the system are a large number of spam emails or a noticeable slowdown in the performance of the network. When these types of issues are noticed sooner, the threat can be successfully blocked. It is critical the employees understand the system and all of the available resources. Mitigation provides advanced resources to protect the system by detecting potential attacks and reacting immediately. Without these resources, the entire network of the business can crash.
Excellent attack prevention is available through DDOS mitigation providers using cloud-based services. This type of service is advantageous for numerous reasons. A private network does not have anywhere near the resources or bandwidth of the cloud. This is critical because so many businesses are strictly reliant on the hardware right on the premises. This makes it easier for an attacker to infiltrate the network. The cloud has apps capable of preventing malicious traffic from reaching their target. Software engineers are constantly monitoring the internet for the newest techniques being used by the attackers. This means they are more aware of what to look for and have the resources to find it faster to prevent the attack. Every company has different needs depending on their network and environment. This does not change the fact that every business must be flexible regarding their security.
The Warning Signs
Every attack has warning signs signaling a potential attack. This includes a slowdown of the network, websites constantly shutting down and issues with the connectivity. Every network can experience issues. When there is a consistent or severe issue with performance, there is a strong possibility an attack is in progress. Action must be taken immediately to protect the network. A service offers increased flexibility for dedicated and cloud hosting and on-premises networks. The components of the infrastructure must be compliant with the highest quality security requirements and standards to be effective. This enables the security to be customized for the specific needs of each business providing the best possible protection against malicious attacks.
The Bottom Line
Unfortunately, there will always be attackers consistently devising new and creative ways to attack a business network. Mitigation is the best way to stay a step ahead of the attacks. Preventing attacks save the business, money, time and a lot of aggravation.
