Most engineers think… Most people picture web-app defence as 'put a WAF in front and you're protected'. That mental model fails you in an interview and in production — a WAF alone cannot absorb a 200 Gbps volumetric flood, and it can be drowned by an encrypted Web DDoS Tsunami before it ever inspects a request. Radware treats it as defence in depth : DefensePro behaviorally scrubs floods at the edge, Alteon load-balances and terminates SSL, the integrated AppWall WAF handles OWASP and app-layer abuse on clean traffic, and Bot Manager reads automation intent to stop scraping and credential stuffing — all managed from APSolute Vision . Each layer owns a distinct threat class; the win is the chain, not any single box. ## ① The threat stack against a web app — why one tool isn't enough Attacks on a web app arrive in different shapes, and each defeats a different defence. A volumetric flood (UDP/ICMP, DNS or NTP amplification) saturates the pipe long before the app sees it. A protocol attack (SYN/ACK floods, TCP state exhaustion, fragmentation) starves the connection table. A Layer 7 'Web DDoS Tsunami' is a high-volume, encrypted HTTPS flood that looks like real requests and exhausts the application. OWASP exploits hunt for bugs (injection, XSS, CSRF), and bots scrape prices and stuff stolen credentials. One tool cannot cover all of that. Radware maps each threat to a layer: DefensePro for volumetric/protocol/L7 floods, the Alteon-integrated AppWall WAF for OWASP and app-layer abuse, and Bot Manager for automated intent. The interview point: name the threat class first, then name the layer that owns it. Legend diagram title threat / attack panel panel border & labels how it works diagram canvas Figure 1 — Four threats, four layers Each web-app threat class is owned by a different Radware layer — no single tool covers all of them. - Four threats, four layers Volumetric flood UDP/DNS amplification — DefensePro scrubs at the edge Protocol attack SYN floods, TCP exhaustion — DefensePro L7 Web DDoS Tsunami Encrypted HTTPS flood — DefensePro X OWASP exploits Injection, XSS, CSRF — AppWall WAF Bots Scraping, credential stuffing — Bot Manager Each web-app threat class is owned by a different Radware layer — no single tool covers all of them. Figure 2 — The Radware defence chain Traffic flows edge-to-app through four layers, each removing a distinct threat class before the app. The Radware defence chain DefensePro behavioral DDoS edge Alteon ADC LB + SSL terminate AppWall WAF OWASP + app-layer Bot Manager IDBA intent Web app clean traffic only Traffic flows edge-to-app through four layers, each removing a distinct threat class before the app. Quick check · Q1 of 10 · Understand Why isn't a single WAF enough to protect a web app? a) WAFs are too slow b) Floods, exploits and bots are different threat classes that need different layers c) WAFs only work in the cloud d) A WAF can only see one IP Correct: b. A WAF inspects HTTP for OWASP exploits but cannot absorb a volumetric flood or an encrypted Web DDoS Tsunami, and it does not read automation intent. Radware maps each threat class to a dedicated layer — DefensePro, AppWall and Bot Manager. 👉 So far: Four threat classes hit a web app — volumetric, protocol, L7 Tsunami and bots — and each needs its own Radware layer; one tool can't cover all of them. ## ② DefensePro — behavioral DDoS at the edge DefensePro is Radware's dedicated DDoS appliance (hardware or virtual). What makes it 'behavioral' is that it learns a normal-traffic baseline automatically and generates real-time signatures for anomalies — so it detects and mitigates in seconds, including zero-day floods, with no manual rules to write. ### What it covers DefensePro spans L3/L4 volumetric (UDP/ICMP floods, DNS/NTP amplification), protocol (SYN/ACK floods, TCP state exhaustion, fragmentation) and L7 (HTTP floods, Slowloris, DNS query floods). DefensePro X adds protection against Web DDoS Tsunami — aggressive, encrypted, high-volume HTTPS L7 floods that evade standard WAFs and network DDoS tools — by decrypting and deep-inspecting L7 headers and adapting mitigation continuously. Figure 3 — How DefensePro stops a zero-day flood Behavioral baselining plus real-time signatures mitigate floods in seconds — no pre-written rules. How DefensePro stops a zero-day flood Baseline learn normal traffic Detect spot the anomaly Signature real-time generated Mitigate block the flood Behavioral baselining plus real-time signatures mitigate floods in seconds — no pre-written rules. 🛡️ DefensePro tap to flip Radware's behavioral, real-time DDoS mitigation appliance for L3–L7 attacks — learns a baseline and generates signatures to stop zero-day floods. 🌊 Web DDoS Tsunami tap to flip An aggressive, encrypted Layer 7 HTTPS flood that evades standard WAFs and network DDoS tools — stopped by DefensePro X. 🧱 AppWall WAF tap to flip Radware's WAF (standalone or Alteon-integrated) with positive + negative security models and full OWASP Top 10 coverage. 🤖 IDBA tap to flip Intent-based Deep Behavior Analysis — Bot Manager's ML engine that judges automation intent, not just request rate. Name the threat class, then the layer In an interview, lead with the threat class — volumetric, protocol, L7 Tsunami, OWASP exploit or bot — then name the Radware layer that owns it (DefensePro, AppWall or Bot Manager). 'It depends what's attacking you' is the wrong answer; the right one maps each threat to its layer. Quick check · Q2 of 10 · Remember What makes DefensePro 'behavioral'? a) It uses only static signature lists b) It blocks all UDP by default c) It learns a normal baseline and generates real-time signatures for anomalies d) It relies on GeoIP blocking Correct: c. DefensePro auto-learns a baseline of normal traffic and generates real-time signatures against anomalies, so it stops even zero-day floods without pre-written rules. 👉 So far: DefensePro is behavioral: it learns a baseline and generates real-time signatures to stop volumetric, protocol and L7 floods, with DefensePro X handling encrypted Web DDoS Tsunami. ## ③ Alteon + AppWall WAF — app-layer protection on clean traffic The WAF can only inspect what it can read, so the Alteon ADC sits in the path as the L4–L7 load balancer and SSL/TLS termination point. It decrypts traffic and hands clean HTTP to the security modules — without that, the WAF and Bot Manager would only see encrypted bytes. ### What AppWall does AppWall is Radware's WAF, integrated on Alteon. It combines a negative (signature) model that blocks known-bad and a positive (whitelist) model that allows only known-good — together giving low false positives plus zero-day coverage. It ships full OWASP Top 10 coverage (injection, XSS, CSRF, broken auth/session, misconfiguration), Auto Policy Generation that builds a tailored policy with little input, API protection (schema enforcement), data-leak prevention (blocks credit-card/SSN leakage) and app-layer DDoS defence (Slowloris, dynamic HTTP floods, login brute-force). It is ICSA-certified, NSS-recommended and PCI-compliant. Figure 4 — Negative vs positive security model AppWall combines both models — block known-bad and allow only known-good — for low false positives plus zero-day cover. Negative vs positive security model Negative (signature) Blocks known-bad patterns OWASP signatures, attack sigs Fast to deploy Misses brand-new attacks Positive (whitelist) Allows only known-good Auto Policy Generation builds it Catches zero-day exploits Needs learning of the app AppWall combines both models — block known-bad and allow only known-good — for low false positives plus zero-day cover. 'Just put a WAF in front' under-sell A WAF cannot absorb a 200 Gbps flood, and an encrypted Web DDoS Tsunami can exhaust it before it inspects a single request. That is why DefensePro scrubs floods upstream and Alteon decrypts SSL first — the WAF only ever works on clean, manageable traffic. Quick check · Q3 of 10 · Apply Encrypted HTTPS traffic must reach the AppWall WAF for inspection. What makes that possible? a) Alteon terminates SSL/TLS and feeds decrypted HTTP to the WAF b) The WAF guesses the payload c) DefensePro decrypts it for the WAF d) Bot Manager forwards the keys Correct: a. Alteon, the ADC, load-balances and terminates SSL/TLS, handing clean decrypted HTTP to the integrated AppWall WAF (and Bot Manager) so they can actually inspect payloads. 👉 So far: Alteon terminates SSL and feeds clean HTTP to AppWall, whose positive + negative models give full OWASP Top 10, API and data-leak protection with low false positives. ## ④ Bot Manager — stopping scraping and credential stuffing Rate limits alone cannot tell a careful bot from a human. Bot Manager uses Intent-based Deep Behavior Analysis (IDBA) plus device/browser fingerprinting, machine learning and collective bot intelligence to model the intent behind each request. That lets it cover the OWASP automated threats: account takeover, credential stuffing, content/price scraping, payment (carding) abuse and denial of inventory . Its mitigation actions are graded, not just allow/deny: Allow, JS Challenge, CAPTCHA, Block, Throttle, Feed Fake Data, Drop, Redirect, Session Termination, Log Only . It protects web, mobile (SDK) and API channels, and can run integrated with AppWall on Alteon so the WAF handles exploits while Bot Manager classifies automation. Everything — DefensePro, Alteon, AppWall and Bot Manager — is managed and reported from APSolute Vision . Figure 5 — APSolute Vision over the whole stack One management plane drives policy and reporting across every Radware layer protecting the app. APSolute Vision over the whole stack APSolute Vision central management DefensePro (DDoS) Alteon (ADC) AppWall (WAF) Bot Manager (IDBA) Web / mobile / API One management plane drives policy and reporting across every Radware layer protecting the app. Meera, IT lead at 'KartBazaar' in Bengaluru, faces this During a Diwali sale the login page slows to a crawl, the fraud team reports a spike in 'wrong password' lockouts and unfamiliar logins, and app-server CPU is pinned even though human traffic looks normal. Likely cause A credential-stuffing botnet is hammering /login with millions of stolen username/password pairs, plus low-and-slow HTTPS requests that the network DDoS view never flags as 'volumetric'. Diagnosis In APSolute Vision the /login cluster is classified by IDBA as 'bad bot — automated tool', with one device fingerprint reused across thousands of IPs; AppWall logs show brute-force rate alerts on the same URL. APSolute Vision ▸ Bot Manager ▸ Analytics (filter path /login) + AppWall logs Fix In Bot Manager ▸ Policy ▸ Mitigation set the /login action to CAPTCHA/JS Challenge for suspected bots and Block for known-bad fingerprints, and enable AppWall's brute-force / rate-based protection on the login form. Verify Failed-login rate drops about 95%, IDBA 'bad bot' volume on /login falls off the dashboard, app-server CPU returns to baseline, and legitimate shoppers (passing the challenge silently) keep checking out. Prove it from the analytics, not a hunch Never close a bot ticket on 'should be fine'. APSolute Vision and Bot Manager Analytics show the IDBA classification, the reused fingerprint and the exact path. That single read tells you whether it's a human spike or a credential-stuffing run — without guessing. ### ▶ Watch a credential-stuffing run get stopped at /login How one bad-bot request is handled end-to-end. Press Play for the healthy path, then Break it to see the classic failure. ① Request A bot posts a stolen username/password pair to /login over HTTPS, blended into Diwali-sale traffic. ▼ ② SSL terminate Alteon load-balances the connection and terminates SSL, handing decrypted HTTP to the security modules. ▼ ③ IDBA classify Bot Manager fingerprints the client and IDBA flags it as an automated tool reusing one device across thousands of IPs. ▼ ④ Challenge + log The bot is served a JS Challenge/CAPTCHA (or blocked); the verdict is logged in APSolute Vision with the path and fingerprint. Press Play to step through the healthy mitigation path. Then press Break it . ▶ Play Next ▶ ⚠ Break it ↺ Reset Quick check · Q4 of 10 · Analyze A botnet is hammering /login with stolen credentials at a human-like rate. What stops it best? a) Volumetric scrubbing b) SSL offload c) DNS protection d) Bot Manager intent detection (IDBA) plus a challenge or block Correct: d. Credential stuffing is automated bot abuse that may not look volumetric. Bot Manager's IDBA and fingerprinting flag the automation intent, then challenge, block or throttle it — rate-based tools alone miss low-and-slow bots. 👉 So far: Bot Manager uses IDBA and fingerprinting to read automation intent across web/mobile/API, with graded actions (challenge, throttle, fake data, block) — all managed from APSolute Vision. ### 🤖 Ask the AI Tutor Tap any question — instant, scoped to this lesson.

Q5 · Remember Which Radware product is the dedicated behavioral network/volumetric DDoS engine? a) AppWall b) DefensePro c) Bot Manager d) Alteon Correct: b. DefensePro is the dedicated DDoS appliance — it uses behavioral baselining and real-time signatures across L3–L7. AppWall is the WAF, Bot Manager handles automation, and Alteon is the ADC. Q6 · Understand AppWall's two security models are: a) Inline + out-of-band b) Positive + negative c) Hardware + cloud d) L3 + L4 Correct: b. AppWall combines a positive (whitelist, allow only known-good) model and a negative (signature, block known-bad) model — together giving low false positives plus zero-day coverage. Q7 · Apply Credential stuffing on a login page is best stopped by: a) Bot Manager intent detection plus a challenge or block b) Volumetric scrubbing c) SSL offload alone d) DNS protection Correct: a. Credential stuffing is automated bot abuse, often at a human-like rate. Bot Manager's IDBA and fingerprinting flag the intent, then challenge, throttle or block it. Volumetric and DNS defences don't see it. Q8 · Analyze Why must Alteon terminate SSL before traffic reaches AppWall and Bot Manager? a) To save bandwidth b) To reduce latency only c) So the WAF and Bot Manager get decrypted HTTP they can inspect and fingerprint d) Because TLS is insecure Correct: c. The security modules can only inspect what they can read. Alteon terminates TLS and hands clean HTTP to AppWall and Bot Manager; without it they'd see only encrypted bytes. Q9 · Evaluate An interviewer asks how Radware defends one web app end-to-end. Best answer? a) Buy one bigger WAF b) Layer DefensePro (edge DDoS), Alteon+AppWall (SSL + OWASP WAF) and Bot Manager (IDBA), managed from APSolute Vision c) Block all traffic and allow-list IPs d) Use DNS filtering only Correct: b. Defence in depth: DefensePro scrubs floods, Alteon terminates SSL into the AppWall WAF for OWASP/app-layer, and Bot Manager reads automation intent — all centrally managed by APSolute Vision. Each layer owns a distinct threat class. Q10 · Evaluate Which capability specifically targets aggressive encrypted Layer 7 HTTPS floods (Web DDoS Tsunami)? a) DefensePro X b) AppWall Auto Policy Generation c) Bot Manager Feed Fake Data d) Alteon FastView Correct: a. DefensePro X adds Web DDoS Tsunami protection — it decrypts and deep-inspects L7 headers and adapts mitigation to encrypted high-volume HTTPS floods that evade standard WAFs and network DDoS tools.

Then compare with the expert version. Compare with expert answer Expert version: Because a web app faces several distinct threat classes that no single tool can cover. A WAF inspects HTTP for OWASP exploits but cannot absorb a volumetric flood, can be drowned by an encrypted Web DDoS Tsunami, and does not read automation intent. So DefensePro behaviorally scrubs floods at the edge, Alteon terminates SSL and feeds the integrated AppWall WAF clean traffic for OWASP and app-layer abuse, and Bot Manager uses IDBA to stop scraping and credential stuffing — all managed from APSolute Vision. The value is the layered chain, each layer owning a threat class, not any single box. ### 🗣 Teach a friend Best way to lock it in — explain it in one line to a teammate.
