Thousands of DDoS attacks are now reported each day, and most are mitigated as a normal course of business with no special attention warranted. But cyber attackers are capable of increasing the scope of the attack \u2014 and DDoS attacks continue to rise in complexity, volume, and frequency. This presents a growing threat to the network security of even the smallest enterprises.<\/em><\/p>\n\n\n\n Gartner, What is Cybersecurity<\/a><\/p>\n<\/blockquote>\n\n\n\n Since DDoS attacks disrupt services that customers rely on, they pose a significant threat to your organization\u2019s reputation, customer satisfaction, and revenue. Therefore, it\u2019s important to take preventive measures against DDoS attacks.<\/p>\n\n\n\n The key principle behind DDoS attacks is to overload the internet bandwidth, CPU, and RAM capacity of targeted networks and services in order to make them inaccessible.<\/p>\n\n\n\n Unlike simple denial of service (DoS) attacks, which come from one system, DDoS attacks leverage multiple systems or devices together. Cyber attackers access these systems by infecting various user devices with phishing attacks and other mass infection techniques. Called a botnet<\/em>, these hundreds or thousands of bots await the malicious server\u2019s command.<\/p>\n\n\n\n Once the command is given, the infected devices try to access the targeted resource all at once, overwhelming the system\u2019s technical capacity to respond to legitimate requests. The flood of traffic consumes bandwidth and system resources, causing the target system to slow down, become inaccessible, or crash altogether.<\/p>\n\n\n\n It is extremely difficult \u2014 and frequently impossible \u2014 to filter out malicious traffic, as it usually comes from regular users\u2019 infected devices widely distributed across the internet.<\/p>\n\n\n\n There are several types of DDoS attacks, most of which fall into four main categories based on the component of the network connection they target.<\/p>\n\n\n\n\t\t Types of DDoS Attacks<\/p>\n\n\n\n\t\t Volumetric attacks<\/p>\n\n\n\t\t\t \n\t\t<\/div>\n\t\n \n\t\t\t\n\t\t<\/div>\n\t\n\n\n\t\t Protocol attacks<\/p>\n\n\n\t\t\t \n\t\t<\/div>\n\t\n \n\t\t\t\n\t\t<\/div>\n\t\n\n\n\t\t Application layer attacks<\/p>\n\n\n\t\t\t \n\t\t<\/div>\n\t\n \n\t\t\t\n\t\t<\/div>\n\t\n\n\n\t\t Multi-vector attacks<\/p>\n\n\n\t\t\t \n\t\t<\/div>\n\t\n \n\t\t\t\n\t\t<\/div>\n\t\n \n\t\t<\/div>\n\t\n\n\t\t\t \n\t\t<\/div>\n\t\n\n\n Examples of volumetric attacks include UDP floods<\/a>, ICMP floods<\/a>, and DNS amplification<\/a>.<\/p>\n\n\n\n Volume-based DDoS attacks are measured in bits per second (bps).<\/p>\n\n\n\n Protocol DDoS attack examples include SYN floods<\/a>, Smurf DDoS attacks<\/a>, and IP fragmentation attacks<\/a>.<\/p>\n\n\n\n Protocol DDoS attacks are measured in packets per second (pps).<\/p>\n\n\n\n Examples of application layer attacks include HTTP floods<\/a>, DNS query floods<\/a>, and Slowloris attacks<\/a>.<\/p>\n\n\n\n Application layer DDoS attacks are measured in requests per second (rps).<\/p>\n\n\n\n If there are signs your network is under a DDoS attack, act fast, as hackers can make your organization vulnerable to other cyberattacks and threats.<\/p>\n\n\n\n Preparing your organization ahead of time is key to prompt detection and response. To prevent a DDoS attack, consider the following best practices:<\/p>\n\n\n\n Detecting a DDoS attack may be challenging as most malicious traffic is usually dispersed and blended into legitimate traffic. However, there are general signs that can help you spot a DDoS attack on your organization:<\/p>\n\n\n\n Monitoring your traffic in real time, establishing network baselines, and leveraging automated traffic alerts can help you recognize these deviations and detect DDoS attacks early on.<\/p>\n\n\n\n In the event of an attack, the following DDoS mitigation techniques will help you stop an assault or reduce its impact on your organization:<\/p>\n\n\n\n To maximize the effectiveness of your DDoS protection efforts, it\u2019s vital to support them with other cybersecurity tools, processes, and services to help you fight other cyber threats.<\/p>\n\n\n\n Consider implementing Syteca<\/a> \u2013 a comprehensive cybersecurity platform. Syteca helps you secure your organization\u2019s inside perimeter by monitoring user activity in real time<\/a>, proactively managing employee access<\/a>, and automatically responding to security events<\/a>.<\/p>\n\n\n\n\t\t Want to try Syteca?
