# DDoS Attack Simulation and Security Testing Service **URL:** https://securesys.com.tr/en/services/ddos-test-service ### What Is DDoS Attack Simulation and Security Testing? DDoS (Distributed Denial of Service) attack simulation and security testing is a controlled cyber security exercise that assesses how well an organisation's internet-facing services hold up against high-volume or high-intensity request traffic. Using genuine attacker techniques, we analyse web applications, API services, DNS infrastructure, email systems, VPN services, network devices and internet links under a range of DDoS scenarios. The aim is to identify the weaknesses that could affect service continuity, verify the effectiveness of the existing protection, and find potential outages before an attacker does. DDoS attacks do not only target the internet link. Today the application layer (Layer 7), API services, DNS infrastructure, TCP/IP protocols and cloud services are all targets. Modern DDoS testing must therefore use multi-dimensional scenarios covering the network, application and service layers. SecureSys DDoS security tests are performed with controlled traffic, in line with internationally accepted [methodology](/en/learning/penetration-testing/penetration-testing-process-and-methodology) and vendor guidance. Operational continuity is protected throughout, and every scenario stays within the scope agreed in advance. ### What Is DDoS (Distributed Denial of Service)? DDoS is a class of cyber attack that renders a system, application or network infrastructure unable to serve, by directing intensive request traffic at it from a large number of devices at once. These attacks are usually launched from compromised computers, servers, IoT devices or botnets. The goal is not to steal data but to slow the service, make it unreachable, or interrupt the organisation's operations. DDoS attacks can affect: - Websites - Web applications - API services - DNS servers - VPN infrastructure - Mail servers - E-commerce platforms - Mobile application services - VoIP systems - Cloud environments - Data centres - Microservice architectures ### What Is the Difference Between DoS and DDoS? A DoS attack originates from a single source, whereas a DDoS attack is launched from thousands or even millions of devices simultaneously. DDoS is therefore far harder to block and places serious strain on network infrastructure. | DoS | DDoS | | --- | --- | | A single attack source | Thousands of attack sources | | Lower traffic volume | Very high traffic volume | | Easier to detect | Harder to detect because the sources are distributed | | Easier to block | Requires advanced protection mechanisms | | Limited impact | Can cause service outage and operational loss | ### The Purpose of DDoS Security Testing DDoS security testing is not carried out merely to subject systems to heavy traffic. The real objective is to measure how well the existing security infrastructure withstands a genuine attack, and to surface any weaknesses under control. The following are assessed: - Capacity of the internet connections - Resilience of firewalls and security appliances - WAF (Web Application Firewall) behaviour - Effectiveness of IDS / IPS systems - Load balancer performance - CDN and reverse proxy configuration - Resilience of DNS services - Performance of API services under load - Accuracy of automatic DDoS protection - Traffic filtering and attack blocking processes - Business continuity - Incident response and crisis management processes ### Is a DDoS Test the Same as a Load Test? No. DDoS security testing, load testing, stress testing and performance testing serve entirely different purposes. | Test type | Purpose | | --- | --- | | Load test | Measures performance under the expected user load. | | Stress test | Pushes past capacity to find the breaking point. | | Performance test | Analyses response times, throughput and resource usage. | | DDoS security test | Uses genuine attack techniques to assess the resilience of the security controls and of service continuity. | The fact that a system copes with heavy user load therefore does not mean it is safe against DDoS. DDoS attacks target network protocols, the application layer, API services and security appliances, and behave quite differently from conventional performance testing. ### The SecureSys DDoS Approach SecureSys does not treat DDoS testing as an exercise in generating high-volume traffic. The engagement is planned with multi-layered attack scenarios covering the network infrastructure, security appliances, application layer, API services and cloud architecture. Through controlled simulations modelled on genuine attacker techniques, we assess not just bandwidth but security policy, automatic protection mechanisms and operational response processes. Organisations can therefore see in advance which systems would be affected in a DDoS attack, which controls would fall short, and what needs to improve to preserve service continuity. #### Scope of DDoS Security Testing SecureSys DDoS security testing is not a matter of generating traffic against the internet link. The engagement is planned to cover the organisation's network infrastructure, security appliances, cloud services, web applications, API services and every internet-reachable critical system. Controlled scenarios modelled on genuine attacker techniques let us analyse the impact of DDoS attacks at different layers and verify how effective the existing protection really is. #### Network Infrastructure Testing The network infrastructure providing internet access is among the first targets in a DDoS attack. We assess in detail how network devices behave under heavy traffic, together with their connection management and traffic filtering. **Network components tested** - Internet links - Metro Ethernet infrastructure - MPLS connections - SD-WAN infrastructure - Routers and switches - Core network - Edge network - VLAN design - NAT services - Routing protocols - QoS configuration #### Firewalls and Security Appliances One of a firewall's core jobs is to filter malicious traffic and preserve service continuity. During DDoS testing we assess connection management, session tables, traffic filtering policy and automatic protection mechanisms. **Security solutions supported** - Fortinet FortiGate - Palo Alto Networks - Sophos Firewall - Check Point - Cisco Secure Firewall - Juniper SRX - SonicWall - WatchGuard - Huawei Firewall **Principal controls analysed** - Stateful inspection - Connection tracking - Session table management - SYN cookies - Flood protection - Rate limiting - DoS policy - IPS integration #### Web Application Firewall (WAF) Application layer (Layer 7) attacks are most often mitigated by a Web Application Firewall. SecureSys testing assesses how effective WAF policy is against genuine attacks. **[WAF solutions](/en/services/waf-solutions-api-security) tested** - Cloudflare WAF - F5 Advanced WAF - Imperva WAF - FortiWeb - ModSecurity - Azure Web Application Firewall - AWS WAF - Google Cloud Armor #### Controls Assessed - HTTP flood protection - HTTPS flood protection - Bot management - CAPTCHA mechanisms - Rate limiting - Geo-blocking - IP reputation - Behavioural analysis #### CDN and Reverse Proxy Infrastructure Content delivery networks and reverse proxies play an important part in absorbing DDoS attacks. Testing analyses CDN configuration, caching behaviour and traffic routing. **Platforms supported** - Cloudflare - Akamai - Fastly - Amazon CloudFront - Azure Front Door - Google Cloud CDN - Bunny CDN #### Load Balancers and Traffic Distribution Load balancing plays a critical role in maintaining service under heavy traffic. DDoS testing assesses the following. - F5 BIG-IP - Citrix ADC - NGINX Plus - HAProxy - AWS Elastic Load Balancer - Azure Load Balancer #### Areas Analysed - Session persistence - Health checks - Failover - Connection limits - SSL offloading - Traffic distribution #### DNS Infrastructure DNS is among the services most frequently targeted in a DDoS attack. If DNS goes down, web applications, email systems and API services all become unreachable. #### Principal Scenarios Tested - DNS flood - DNS amplification - Recursive DNS security - Open resolver checks - Anycast design - DNS failover - Rate limiting #### API Security API services are the backbone of modern applications, and under high request volumes their performance and security must be assessed together. **Services tested** - REST API - GraphQL API - SOAP services - API gateway - Microservice architectures #### Controls - Rate limiting - Request throttling - JWT validation - OAuth - Back-end resilience - Timeout management - Caching mechanisms #### VPN and Remote Access Infrastructure VPN services are critical systems, particularly because remote staff depend on them for access. DDoS testing analyses how VPN services perform under heavy connection load, along with their security controls. #### Platforms Supported - FortiClient VPN - Cisco AnyConnect - Palo Alto GlobalProtect - OpenVPN - WireGuard - IPSec VPN - SSL VPN #### Email and Communication Systems Corporate email infrastructure can also be affected by DDoS. Controlled testing against SMTP and IMAP services assesses connection limits and service continuity. **Systems tested** - Microsoft Exchange - Microsoft 365 - Google Workspace - Postfix - Exim - Zimbra #### Cloud Infrastructure Even where cloud DDoS protection is active, misconfiguration can still cause outages. SecureSys assesses whether the security services offered by the cloud provider are configured correctly, and how they behave against a genuine attack. #### Platforms Supported - Amazon Web Services (AWS) - Microsoft Azure - Google Cloud Platform (GCP) - Oracle Cloud Infrastructure (OCI) - Alibaba Cloud - OpenStack #### Security Services Tested - AWS Shield Standard / Advanced - AWS WAF - Azure DDoS Protection - Azure Front Door - Google Cloud Armor - Cloudflare Magic Transit - Akamai Prolexic - Radware DefensePro - Arbor DDoS Protection #### Application and Service Resilience We also analyse the effect DDoS attacks can have at the application and service level, not just on the network. The resilience of the following is assessed: - Web servers - Application servers - API gateways - Microservices - Database servers - Redis and Memcached - Kubernetes services - Docker container environments - Message queues (RabbitMQ, Kafka and similar) - Authentication services (LDAP, Active Directory, Entra ID) - File sharing services - VoIP and SIP servers #### The SecureSys Approach SecureSys DDoS security testing evaluates every component through a single lens — from the network infrastructure to the application layer, from cloud services to security appliances. The engagement aims not merely to generate attack traffic but to measure the effectiveness of the security controls, the incident response processes, service continuity and how the systems hold up against a genuine attack. This comprehensive approach shows organisations clearly which systems carry the greatest risk during a DDoS attack, whether the existing protection is adequate, and where the infrastructure needs strengthening. #### Types of DDoS Attack DDoS attacks fall into different categories according to the layer they target and the technique they use. Some aim to exhaust internet bandwidth, others target network protocols, and others set out to disable web applications and API services directly. SecureSys DDoS security testing determines the scenarios that suit the organisation's infrastructure and simulates the different attack types safely and under control. This assesses the resilience not only of the internet link but of the security appliances, the application layer and the critical services. #### Volumetric DDoS Attacks Volumetric attacks aim to exhaust the target's internet bandwidth with heavy data traffic. The goal is to fill the link completely so that legitimate users cannot reach the service. These attacks can generate millions of packets per second (PPS) or hundreds of gigabits per second (Gbps), and are usually launched from botnets. The principal attacks tested: - UDP flood - ICMP flood - DNS amplification - NTP amplification - SSDP amplification - Memcached amplification - CLDAP amplification - CHARGEN amplification - WS-Discovery amplification #### UDP Flood A UDP flood is a volumetric attack that sends very large numbers of UDP packets at the target to exhaust the processing capacity of network devices and servers. Because servers attempt to respond to every UDP packet, processor and network resources drain quickly. DNS, VoIP and game servers are particularly badly affected. **Controls tested** - Firewall behaviour - IPS protection - Rate limiting - UDP filtering - Traffic analysis - Anti-DDoS mechanisms #### ICMP Flood An ICMP flood sends large numbers of ICMP echo request (ping) packets at the target, aiming to exhaust the processing capacity of network devices and generate enough traffic to disrupt service. The test assesses how resilient the network infrastructure is to ICMP traffic. #### DNS Amplification DNS amplification is a reflection and amplification attack in which small DNS queries cause much larger DNS responses to be sent to the target. The technique lets an attacker generate very high traffic volumes from very little resource. Testing assesses: - Open DNS resolvers - DNS rate limiting - Recursive DNS configuration - Anti-spoofing controls #### NTP Amplification A reflection attack exploiting features such as "monlist" on NTP servers. A small request becomes a response dozens of times larger, subjecting the target to heavy traffic. #### SSDP Amplification A reflection attack carried out over the SSDP protocol used by UPnP services. Because of IoT devices, large numbers of open SSDP services remain reachable on the internet and can be abused by attackers. #### Memcached Amplification One of the most powerful DDoS attacks, arising from misconfigured Memcached servers. In some cases the amplification factor reaches as high as 50,000×. Testing analyses: - Open UDP Memcached services - Authorisation controls - Internet exposure #### CLDAP Amplification A reflection attack targeting the Connectionless LDAP (CLDAP) services used in Microsoft Active Directory environments. Misconfigured LDAP services can be abused to generate high-volume traffic. #### CHARGEN Amplification A reflection attack over the Character Generator (CHARGEN) protocol, one of the older network services. Rarely used on modern systems, but still a risk on misconfigured legacy devices. #### Protocol (Layer 3 / Layer 4) DDoS Attacks Protocol-based DDoS attacks exploit the way TCP/IP works in order to exhaust server resources. They mostly target firewalls, IPS, load balancers and the operating system's network stack. SecureSys testing can assess the following attacks: - SYN flood - ACK flood - RST flood - FIN flood - TCP fragmentation - Ping of Death - Smurf attack - LAND attack - Teardrop attack - Fragmentation attack - Connection exhaustion - State exhaustion #### SYN Flood The SYN flood is one of the most common DDoS attacks, targeting the three-way handshake that establishes a TCP connection. By sending millions of SYN packets, the attacker forces the server to hold large numbers of half-open connections. The connection table fills up and new users can no longer connect. Testing analyses: - SYN cookie mechanisms - Firewall protection - Connection limits - Timeout values #### ACK Flood An ACK flood sends intensive ACK packets at the target to strain the processing capacity of firewalls and IPS devices. The connection tables of stateful firewalls in particular are tested under heavy load. #### RST Flood An RST flood aims to force TCP connections closed. Heavy RST traffic can terminate existing sessions and cause applications to lose their connections. #### FIN Flood This attack uses FIN packets to target the TCP connection management of network devices. Firewall behaviour and TCP session management are analysed. #### Ping of Death The Ping of Death uses oversized ICMP packets to provoke unexpected behaviour in the target. Most modern systems are protected against it, but it remains a scenario worth checking on legacy devices. #### Smurf Attack A Smurf attack abuses ICMP broadcast so that large numbers of devices respond to the same target. It belongs to the reflection class of attacks. #### LAND Attack A LAND attack sends the target TCP packets whose source and destination IP addresses are identical. Modern operating systems are largely protected, but it remains a scenario worth assessing on older network devices. #### Teardrop Attack A classic technique targeting the errors that can occur while fragmented IP packets are reassembled. It can cause instability on legacy operating systems. #### Connection Exhaustion Connection exhaustion attacks aim to consume a server's maximum connection capacity. This attack is tested particularly against: - Reverse proxies - Load balancers - VPN servers - API gateways - Web servers #### Application Layer (Layer 7) DDoS Attacks Application layer DDoS attacks target web applications, API services, user sessions and application logic directly. Rather than generating high bandwidth, they aim to exhaust the server's processing capacity, its database or its application resources. Because Layer 7 attacks often resemble ordinary user traffic, they are harder for conventional firewalls and network-based DDoS protection to detect. Web Application Firewalls (WAF), behavioural analysis, bot management and advanced threat detection are therefore critical. SecureSys DDoS security testing applies controlled Layer 7 scenarios against web applications and API services to assess how effective those controls really are. #### HTTP GET Flood An HTTP GET flood sends large numbers of GET requests to a web server or application in order to exhaust its resources. Static files, dynamic pages, images or database queries are called repeatedly, placing load on CPU, RAM and the application's worker threads. **Controls tested** - WAF behaviour - Rate limiting - CDN protection - Caching mechanisms - Bot protection systems - Web server performance #### HTTP POST Flood An HTTP POST flood sends intensive POST requests to the server, usually through login forms, order screens, search boxes or API services. Because POST operations generally require server-side processing, they can consume considerably more resource than a GET flood. Testing analyses: - Form security - Application business logic - API services - Database performance - Processing queues #### HTTPS Flood HTTPS floods exploit the TLS/SSL encryption process to exhaust the server's processing capacity. Because encryption and key exchange are computationally expensive, we assess how systems hold up under heavy HTTPS traffic in particular. **Principal controls assessed** - SSL offloading - TLS configuration - Load balancer behaviour - Certificate management - WAF performance #### HTTP/2 Rapid Reset Attack The HTTP/2 Rapid Reset attack is a modern DDoS technique that targets the session management mechanisms in the HTTP/2 protocol. The attacker opens and cancels a very large number of HTTP/2 requests in a short window, exhausting server resources. In recent years this method has been used against several major technology providers and has produced some of the largest Layer 7 attacks in the history of the internet. Testing assesses: - HTTP/2 support - Reverse proxy behaviour - WAF protection - Rate limiting - Connection management #### Slowloris Attack Slowloris is the best known of the low-bandwidth Layer 7 attacks. The attacker opens a large number of HTTP connections but never completes the requests. The web server's connection pool fills up, and legitimate users can no longer be served. This scenario analyses: - Keep-alive settings - Timeout values - Maximum connection limits - Reverse proxy behaviour #### Slow POST Attack In a Slow POST attack the HTTP POST request is transmitted extremely slowly. Because the server waits for the request to complete, connections stay open for a long time and resources are consumed. We assess the behaviour of servers including: - IIS - Apache - NGINX - Tomcat #### Slow Read Attack In a Slow Read attack the client reads the server's response at a very low rate, keeping the connection open far longer than necessary. This is particularly effective at consuming resources during large file downloads. #### HTTP Header Flood HTTP header floods use very large or very numerous HTTP headers to strain the application's parsing mechanisms. Testing assesses: - Header limits - Proxy behaviour - WAF controls - Memory usage #### Cookie Flood Attack Cookie flood attacks send numerous or oversized cookie values to target the application's session management. This scenario analyses: - Session management - Memory consumption - Cookie limits - WAF behaviour #### API DDoS Attacks API services are now among the most critical targets in any modern organisation. Mobile applications, web applications, microservice architectures and third-party integrations run largely on API infrastructure. How well those API services withstand DDoS therefore matters enormously. #### REST API Flood Intensive GET, POST, PUT or DELETE requests are directed at REST API services to target the application layer. Testing analyses: - API gateway - Rate limiting - Authentication - JWT validation - Back-end services #### GraphQL DDoS Attack Because a single GraphQL query can request a great deal of data, complex queries can place serious load on the server. Testing assesses: - Query complexity - Query depth - Resolver behaviour - Timeout controls #### WebSocket Flood WebSocket services used for real-time communication can be targeted with large numbers of concurrent connections. This attack can cause heavy resource consumption on: - Chat applications - Financial systems - Game servers - IoT platforms #### SIP Flood An attack directed at the SIP protocol used in VoIP systems. It is a critical test scenario for the service continuity of IP PBX systems and call centres. #### SMTP Flood Intensive connections to SMTP services attempt to exhaust the resources of the mail servers. This scenario analyses: - Mail gateway - Spam filters - Connection limits - Mail queue management #### Botnet-Based DDoS Attacks Most DDoS attacks today are launched from botnets. Compromised computers, servers, IoT devices and mobile devices are directed by a single command centre to send traffic at the target simultaneously. SecureSys DDoS security testing applies controlled scenarios that imitate botnet behaviour, assessing how effectively the organisation detects and blocks such traffic. #### Botnet Scenarios Available for Testing - IoT botnet simulation - Mirai botnet behaviour - Meris botnet traffic analysis - Residential proxy traffic - Proxy bot simulation - Distributed HTTP bot traffic - Distributed HTTPS traffic - Hybrid DDoS scenarios **How the DDoS Security Testing Process Works** SecureSys DDoS security tests are carried out using controlled traffic, within a scope agreed in advance, and without putting the organisation's operational continuity at risk. Before every test, the target systems, the permitted attack scenarios, the traffic limits and the test windows are planned together with the client. Security controls are therefore assessed against scenarios as close as possible to a real attack, while the production environment stays protected. #### \1. Scoping and Planning The first stage establishes the scope of the DDoS simulation. Which systems will be tested, which services are critical and which attack scenarios will be applied are all planned together with the client. This stage defines: - IP addresses to be tested - Domains and subdomains - Web applications - API services - VPN systems - DNS infrastructure - Cloud services - Security appliances - Test time windows - Traffic limits - Emergency stop procedures #### \2. Analysis of the Existing Infrastructure Before testing begins, the current network architecture and security infrastructure are analysed. The purpose is not simply to generate an attack, but to understand how the existing defences actually work. The principal components examined: - Internet egress capacity - Firewall policy - WAF configuration - CDN usage - Load balancer architecture - DNS services - Cloud security services - Rate limiting policy - IPS / IDS rules - SIEM and log management #### \3. Risk Analysis and Scenario Design Every organisation has a different risk profile. A bank and an e-commerce platform do not face the same attacks. Equally, the scenarios that suit an API-heavy SaaS platform differ from those for a conventional corporate website. SecureSys specialists therefore build attack scenarios around the organisation's line of business. For example: - HTTP flood - HTTPS flood - API flood - DNS flood - SYN flood - UDP flood - Slowloris - GraphQL flood - WebSocket flood are planned according to the risk analysis. #### \4. Running the Controlled DDoS Simulations Controlled DDoS attacks are launched in line with the agreed scenarios. The attacks stay within traffic limits agreed in advance, and the entire process is monitored live by SecureSys specialists. Throughout this stage we track: - Traffic volume - Packets per second (PPS) - Bandwidth consumption (BPS) - Active connections - CPU usage - Memory consumption - Firewall behaviour - WAF behaviour - Server response times #### \5. Real-Time Monitoring and Analysis During the simulation, both SecureSys specialists and the organisation's own technical teams can observe system behaviour at the same time. The following are assessed: - Firewall logs - WAF logs - SIEM events - Server logs - Network traffic - NetFlow analysis - CPU and RAM usage - Disk I/O - Application performance - API response times - CDN traffic - Load balancer behaviour #### \6. Verifying the Protection Mechanisms One of the most important parts of a DDoS test is not generating the attack but confirming that the defences respond correctly. We analyse each of the following in turn: - Firewall rules - IPS behaviour - Rate limiting - Geo-blocking - Bot protection - CAPTCHA - CDN behaviour - Automatic mitigation - Cloud DDoS protection - WAF policy #### \7. Risk Assessment Once testing is complete, all technical findings are analysed and risk levels assigned. Each finding is assessed against criteria including: - Severity of impact - Likelihood - Effect on business continuity - Risk of service outage - Financial impact - Operational impact Standard CVSS scoring can also be applied to technical findings where it is appropriate. #### \8. Preparing the Technical and Executive Reports Two separate reports are produced at the end of the test. **[Executive summary](/en/learning/penetration-testing/what-a-penetration-test-report-contains)** A report written for senior management that requires no technical background. It covers: - Overall security posture - Critical risks - Assessment of service continuity - Business impact analysis - Recommendations for management - Priority actions #### Technical DDoS Test Report The detailed report prepared for technical teams. It contains: - Attack scenarios executed - Traffic values used - PPS / BPS analysis - System behaviour - Firewall results - WAF results - Server performance - Log records - Evidence screenshots - Remediation recommendations #### \9. Remediation and Retest Once the recommended improvements have been completed, SecureSys can carry out verification testing. The retest checks whether the previously identified gaps have been closed and re-assesses the organisation's current resilience to DDoS attacks. #### Methodologies and Standards Applied SecureSys DDoS security testing is conducted in line with internationally accepted security standards and best practice. The principal reference methodologies: - NIST Cybersecurity Framework (CSF) - NIST SP 800 series - PTES (Penetration Testing Execution Standard) - OWASP Testing Guide - MITRE ATT&CK framework - CIS Controls - ISO/IEC 27001 - ISO/IEC 22301 (business continuity) - ENISA good practices - FIRST incident response best practices #### The SecureSys Testing Approach SecureSys does not treat DDoS testing as a technical exercise in generating high-volume traffic. The engagement follows a complete methodology covering **planning, controlled simulation, real-time monitoring, verification of the security controls, risk analysis, reporting and remediation**. Organisations therefore see not only their current resilience but also receive the technical and operational recommendations that will improve service continuity. **What You Receive at the End of a DDoS Security Test** Once the test is complete we prepare a detailed technical report the engineering team can act on, together with an executive summary that lets senior management assess the risks quickly. The reports set out not only the findings but their effect on business continuity, their risk level and the remediation you can apply. #### Executive Report A summary report written for senior management that requires no technical background. It presents: - The organisation's overall DDoS resilience - Critical security risks - Effects on business continuity - Service outage scenarios - Priority areas for improvement - Recommendations at management level #### Technical DDoS Security Test Report The detailed analysis report that technical teams can use directly. It contains: - Test scope - Attack scenarios executed - Traffic types used - PPS (packets per second) analysis - BPS (bits per second) analysis - Connection statistics - Firewall behaviour - WAF analysis - CDN performance - API behaviour - DNS resilience - Server performance analysis - CPU and RAM usage graphs - Event logs - Proof-of-concept screenshots - Risk assessments - Technical remediation recommendations #### Risk Prioritisation Every finding is prioritised on its technical significance and on its effect on business continuity. Risk is assessed against the following levels: - Critical risk - High risk - Medium risk - Low risk - Informational #### Which Organisations Need DDoS Security Testing? DDoS attacks are a significant risk for any organisation delivering services over the internet. Regular DDoS testing matters particularly in sectors where service continuity is critical, because it prevents operational outages. This service is recommended especially for: - Banks and financial institutions - Insurance companies - E-commerce platforms - Public sector institutions - Defence industry - Telecom operators - Healthcare providers - Energy and infrastructure companies - Logistics companies - Data centres - Cloud service providers - SaaS and technology companies - Gaming platforms #### Technical Remediation Recommendations Actionable technical recommendations are provided against the findings. For example: - Firewall policy optimisation - WAF rule improvements - Rate limiting configuration - CDN optimisation - DNS security configuration - API protection mechanisms - Bot management - Traffic filtering - Cloud DDoS protection services - Network architecture improvements #### Proof of Concept Every attack scenario executed is reported with verifiable technical evidence. Evidence may include: - Traffic graphs - Firewall logs - SIEM records - WAF logs - Server performance screens - Network analysis - Packet captures (PCAP) - System logs #### Retest Once the improvements are complete, verification testing is carried out on request to confirm the effectiveness of the measures taken. #### Why SecureSys? DDoS security testing is not a matter of generating high-volume traffic. A successful assessment requires the attack techniques to be applied correctly, the security controls to be analysed in detail, and service continuity to be evaluated under realistic attack scenarios. Our DDoS security testing follows a multi-layered approach covering not only the internet link but the network infrastructure, security appliances, web applications, API services, cloud platforms and the application layer. Through controlled simulations grounded in real adversary behaviour, we analyse not only the organisation's current security posture but also its incident response processes and operational resilience. #### The SecureSys Difference - Expert penetration testing under TSE TS 13638 - Layer 3, Layer 4 and Layer 7 DDoS attack simulation - Controlled execution of volumetric, protocol and application layer attacks - Comprehensive test scenarios for API, DNS, web, VPN and cloud services - Effectiveness analysis of firewall, WAF, CDN and anti-DDoS solutions - Controlled traffic simulation based on genuine attacker techniques - Risk-driven assessment with prioritised remediation guidance - Comprehensive reporting at both technical and executive level - Post-remediation retest support - Support for a live, observable DDoS platform
