# Prove Check Point is working — first tool + proof field Source: https://ai.techclick.in/blog_checkpoint_evidence_desk Markdown: https://ai.techclick.in/blog_checkpoint_evidence_desk.md Publisher: Techclick Infosec Pvt Ltd How you prove Check Point is working: fw stat, fw log / SmartConsole Logs, fw ctl zdebug drop, cphaprob state, SmartView. Five tickets with first tool and one proof field. Quick answer (say this out loud) fw stat answers “what policy did this gateway actually install, and when?” fw log / SmartConsole Logs answers “what Action , which Rule , which Origin ?” fw ctl zdebug drop answers “why did the kernel drop it when there is no log row?” cphaprob state answers “is this member ACTIVE?” SmartView / the Log Server answers “where do the logs actually live?” A green toast is not a DATE . Cluster green is not an Accept. ## 1. Why “is it working?” is five questions Operators collapse five failures into one sentence. The gateway never took tonight’s package. Policy dropped the 5-tuple. The kernel dropped it before a log row existed. You SSHed the STANDBY member. SmartConsole is pointed at the SMS while the gateways send logs to a dedicated Log Server. Those are five first clicks. This page is the night-shift desk for proof . The factory taught the five stamps (topology, installed policy, access rule, NAT, blade). Here you learn the five tools you actually open, in order, when someone asks you to prove Check Point is working. Hero · five tiles, one ticket Notice: five tiles, not one “SmartConsole dashboard.” You pick the tile that matches the question, then you quote one field. Interview line If they say “prove Check Point is working,” do not say “I opened SmartConsole.” Say: “I prove the install with fw stat POLICY + DATE , the transaction with Logs Action + Rule + Origin , a silent kernel drop with fw ctl zdebug drop , the member with cphaprob state , and the log store with SmartView on the Log Server — not the SMS toast.” ## 2. Mental model — five proof tools Memorise five named objects before you click. Each tool is allowed to prove one thing. Over-claiming a field is how you ship Any-Any at 02:00. #### 1 · fw stat Expert mode on the Security Gateway. Official columns: POLICY (name of the installed policy) + DATE (last policy installation). Does not prove a 5-tuple or who is ACTIVE. #### 2 · fw log / Logs CLI fw log -n -c drop , or SmartConsole Logs & Monitor → Logs (R81.20) / Logs & Events → Logs (R82). Proves one transaction: Action + Rule + Origin . #### 3 · fw ctl zdebug drop Live kernel drop trace (sk167457, R81.20 / R82). Proves the drop reason when Track is None or the drop never became a log. Short window. Stop it. #### 4 · cphaprob state Expert: cphaprob state . Clish: show cluster state . Proof field is member State — ACTIVE, STANDBY, DOWN, READY, INIT. HA Active Up: only ACTIVE forwards. #### 5 · SmartView / Log Server Browser: https://<Server IP>/smartview/ on the SMS or the dedicated Log Server / SmartEvent Server. Empty SMS Logs is often the wrong store, not “the firewall is down.” #### Hard words, once SMS = Security Management Server (design plane). Origin = the gateway object that generated the log. Log Server = dedicated store. Official R81 CLI still documents fw stat ; it also says use cpstat -f policy fw . Flow 1 · five tools, one question each Five proof tools and the one question each is allowed to answer - Write 5-tuple + UTC first · then pick the tool Is Check Point working? five questions, not one fw stat This box installed? POLICY + DATE Expert on the gateway or cpstat -f policy fw not a 5-tuple verdict fw log / Logs This 5-tuple? Action + Rule Origin Logs tab · fw log -c not member State zdebug drop Silent kernel drop? drop reason + Interface / flags fw ctl zdebug drop not a policy editor cphaprob This member? State ACTIVE / STANDBY or show cluster state not an Accept SmartView Where are logs? Log Server /smartview/ not the SMS toast empty ≠ down Empty Logs on the SMS is data. It often means the store, not the blade. Do not invent an Access rule from an empty SMS tab. Start at fw stat, cphaprob, or the Log Server. Read left → right. Each box is allowed one claim. If you cannot name the field, you are not proving — you are guessing. Say this out loud I prove the install, then the log row, then the silent drop, then the member, then the log store. I do not add Any-Any, fail over ClusterXL, or trust the toast until I can quote the field that made me do it. ## 3. Decision flow — ticket → first tool Flowchart first. Do not open the Access Control editor until a diamond says so. Path · pick the branch before the menu Notice: the diamond is the ticket. The path is the tool. The field comes last. Do not reverse that order. Flow 2 · first-tool diamond Decision diamond from symptom to first proof tool Symptom first · tool second · field third What must we prove? After an install or already a flow? Toast / “is it up?” fw stat POLICY + DATE One flow blocked Logs / fw log Action + Rule + Origin No log row zdebug drop drop reason Cluster “green” cphaprob state member State Logs empty SmartView Log Server fw stat DATE older than the toast → stop. There is no new Rule to chase. Reinstall on this member (or fix FWD). Then re-open Logs. Diamond = decision. Do not add Any-Any from the bottom box. R81.20 labels the view Logs & Monitor. R82 labels it Logs & Events. Same Logs tab. Read the diamond first. Silent drop never starts in the Access editor. Empty SMS Logs never starts as “Check Point is down.” A stale DATE never starts as a new Accept. ## 4. How to choose — first tool + proof field Print this next to SmartConsole. If you cannot recite the proof field, you are not ready to change anything. If the ticket says… First tool (official path) Proof field Do not open first After Install Policy / “is Check Point even working?” Expert on the gateway (ACTIVE member): fw stat . Twin: cpstat -f policy fw POLICY (installed policy name) + DATE (last policy installation) A new Any-Any; the SMS toast One SaaS / 5-tuple blocked after a policy change R81.20: Logs & Monitor → Logs . R82: Logs & Events → Logs . CLI twin: fw log -n -l -c drop Action (Drop / Accept / Reject / Prevent / Block) + Rule + Origin Threat Prevention disable; reboot User fails, Logs empty for that 5-tuple, Track may be None Expert, short window: fw ctl zdebug drop (sk167457) Kernel drop reason (plus Interface / TCP flags on the line) Unfiltered zdebug left running; Any-Any Cluster “green” / empty connections / you SSHed .12 Expert cphaprob state or Clish show cluster state Member State (ACTIVE / STANDBY / DOWN / READY) + Cluster Mode cphastop ; calling ClusterXL the outage SmartConsole Logs empty; toast still green Browser https:// /smartview/ , or Logs tab while connected so you see all Log Servers Same Action + Rule + Origin on the server that actually stores the files Declaring the gateway down from an SMS-only tab Official naming, once R81 / R81.20 Logging and Monitoring: SmartConsole > Logs & Monitor and SmartView at https:// /smartview/ . R82 Logging and Monitoring Clients: the same work lives under SmartConsole > Logs & Events . The Logs view replaced SmartView Tracker. This lesson quotes both labels; do not invent a third menu. ## 5. Runbook Side A → B → C Side A proves the gateway (CLI). Side B proves the log row in SmartConsole / SmartView. Side C is the paste that closes the ticket. On a messy Sev-2, do them in this order until a field lights up. ### Side A — CLI on the gateway #### Name who is ACTIVE before you trust any other command Expert: cphaprob state . Clish: show cluster state . Official ClusterXL / CLI Reference: in High Availability (Active Up), only one member must be ACTIVE ; the peer is STANDBY and does not forward. ACTIVE(!) still forwards but a Critical Device is in problem. Quote State and Cluster Mode. If you are on STANDBY, move. Do not debug an empty connections table on the wrong box. - #### Prove what this box installed On that ACTIVE member: fw stat . Official output headers are HOST , POLICY , DATE . R81 CLI Reference: name of the installed policy, date of the last policy installation, and the interfaces the policy protects ( [>eth0] inbound, [ if you already know the object). Official fw log fields include Action , Origin , IfDir , InterfaceName , src , dst , proto , rule_name / rule_uid , layer_name . -n skips DNS (default, and faster). -c drop is the documented action filter; the command still always prints Control ( ctl ) lines. Alert: spoof is a documented alert type — that is topology, not a missing Accept. - #### If there is still no row, take a short zdebug sk167457 (R81.20, R82): fw ctl zdebug drop views drops on the Security Gateway. It is a live kernel debug — reproduce the 5-tuple, quote the drop reason (and Interface / TCP flags on that line), then stop it (Ctrl+C). Do not leave it running. Do not start here if Logs already named a Rule.

It is still a debug on a production firewall. Filter to the 5-tuple in your head (watch only that src/dst), run it for the reproduce window, stop it. If you need hours of drop history, that is fw log / the Log Server — not a debug left attached to the kernel. ### Side B — SmartConsole Logs (and SmartView) - #### Open the Logs tab, not the Access editor R81.20: left pane Logs & Monitor → Logs . R82: Logs & Events → Logs (or Queries). Official search: click Enter Search Query (Ctrl+F) in the query search bar. Time Period first — match the ticket’s UTC window. - #### Filter with documented fields Working with Logs (rule-log pane) lists Source, Destination, Blade, Action, Service, Port, Source Port, Rule, Origin, User . Searching the Logs (R82) documents the Action filter values: Accept (Access Control allowed), Drop (Access Control blocked, no notify), Reject (TCP RST to the source), Block (URL Filtering / Application Control), Prevent (DLP or Threat Prevention), Detect , Encrypt / Decrypt . Example query: action:Drop origin:CP-LAB-01 src:192.0.2.25 . - #### Read Action, then Rule, then Origin Open the row. Quote Action , Rule (name and/or number / Rule UID), Origin (the gateway object). Add Interface / CLI InterfaceName and, for TCP, the flags you see on the details pane (a Reject officially notifies with TCP RST). If Origin is the STANDBY member, you asked the wrong box. - #### If the SMS Logs tab is empty, change store — not policy Understanding Logging: gateways send logs to the Management Server by default, or to a dedicated Log Server , or keep them local. To see logs from all Log Servers, connect SmartConsole to the Management Server and stay in the Logs tab. SmartView Web Application is the same real-time view in a browser: https:// /smartview/ where Server IP is the SMS or the SmartEvent / Log Server that actually indexed the files. The Install Policy toast never wrote a log row. lab-sms.example · SmartConsole · Logs & Events · Logs Training mock · not live Logs & Events / Logs · R81.20 twin: Logs & Monitor / Logs ### Logs Query search bar action:Drop origin:CP-LAB-01 src:192.0.2.25 Time Period Last 15 minutes Action Drop Origin CP-LAB-01 Time Action Origin Rule Interface Source → Dest 01:41:02 Accept CP-LAB-01 Finance-SaaS eth1 192.0.2.40 → 198.51.100.80 01:42:19 Drop CP-LAB-01 Cleanup eth1 192.0.2.25 → 198.51.100.80 Clear Refresh (F5) Lab identities and RFC 5737 / 192.0.2.0/24 addresses only.

No second Accept until residual control is named. ## 6. Five tickets as full stories These five land every quarter. Memorise first tool + proof field. Times and identities below are lab-only (RFC 5737 / 192.0.2.0/24). Journey · one amber hop is the ticket Notice: SmartConsole can still show a green toast while the DATE on this member is yesterday. That is an fw stat ticket, not an Access ticket. Ticket Symptom First tool Proof field CEVD-01 “Is Check Point even working?” after a 01:10 install fw stat on ACTIVE POLICY + DATE CEVD-02 Finance HTTPS to SaaS fails after a rule change Logs tab / fw log -c drop Action + Rule + Origin CEVD-03 Same 5-tuple fails; Logs empty; Track may be None fw ctl zdebug drop Kernel drop reason CEVD-04 Cluster object looks fine; you SSHed 192.0.2.12 cphaprob state Member State CEVD-05 SMS Logs empty; toast still green SmartView on the Log Server Same Action/Rule/Origin on the real store ### CEVD-01 — Prove the install (fw stat) 01:42 · P2. Change window ended at 01:18. SmartConsole showed Policy installed successfully. Finance still hits yesterday’s cleanup. L1 already drafted Any-Any. First tool: SSH the ACTIVE member (prove that with cphaprob state if you are not sure), then fw stat . If DATE is old: quote POLICY + DATE . The toast published a recipe. This box did not take it. Next is per-member install result / FWD — not a new Access rule. If DATE matches 01:18: the package is live. Now you are allowed to open Logs for the 5-tuple. fw stat is not Action . Trap Do not trust a colleague’s fw stat from the STANDBY member or from last week’s change notes. The proof is this gateway, this minute. Official twin if your site retired fw stat : cpstat -f policy fw → Policy name + Install time. ### CEVD-02 — Prove the transaction (Logs) 02:05 · P2. Outlook-adjacent SaaS (lab dest 198.51.100.80 ) fails from 192.0.2.25 after last night’s cleanup tidy. Someone wants “another Accept for Any.” First tool: Logs & Events → Logs (R82) or Logs & Monitor → Logs (R81.20). Query src:192.0.2.25 dst:198.51.100.80 in the last hour. CLI twin: fw log -n -l -c drop . Proof field: Action = Drop, Rule = Cleanup (or the named rule that actually hit), Origin = CP-LAB-01. That name is the ticket. Change that one rule — or the object it missed — Publish, Install, then re-read the same three columns. If Action is Prevent, you are in Threat Prevention, not Access. If Action is Reject, the source got a TCP RST — quote that; do not call it “the app is down.” Close I would not add a second Accept. I would quote Action + Rule + Origin on the failing 5-tuple. Install is not proof until the same filter returns Accept from the same Origin. ### CEVD-03 — Prove the silent drop (zdebug) 02:20 · P1. Same 5-tuple. Logs query is empty. The hit rule’s Track column is None, or Anti-Spoofing / an implied path never wrote a row the indexer sees. L1 wants Any-Any “so we get a log.” First tool: on ACTIVE, fw ctl zdebug drop (sk167457). Reproduce once. Quote the drop reason. Stop the debug. Proof field: the kernel reason — Address spoofing (topology; factory stamp 1), out-of-state TCP (flags on the line), SecureXL / chain drop, or the implied/rule path. Official Anti-Spoofing: a packet whose source does not belong behind that interface is blocked; configure it under Gateways & Servers → gateway → Network Management → interface Topology / Perform Anti-Spoofing based on interface topology. That is not a missing Accept at the top of Standard. Close Empty Logs is the clue the drop never became a Track=Log row. Quote the zdebug reason + Interface. Fix topology or the Track column, then wait for an Action row. Do not leave zdebug running and do not add Any-Any to “generate evidence.” ### CEVD-04 — Prove the member (cphaprob) 02:40 · P2. Cluster object in SmartConsole looks fine. You SSHed 192.0.2.12 because it answered first. Connections look empty. Two apps “fail.” L1 wants cphastop . First tool: cphaprob state / show cluster state . Proof field: State . Lab: 192.0.2.11 ACTIVE 100% load, 192.0.2.12 STANDBY 0% load, Cluster Mode High Availability (Active Up). Official table: STANDBY waits for the Active member to fail before it forwards. Empty logs / empty fw tab -t connections on STANDBY are expected. Retest the 5-tuple on ACTIVE. DOWN means a Critical Device reports problem — that is a different ticket than “add a rule.” Trap Cluster green is not application recovery. cphastop is change-control. Reading Logs filtered to the STANDBY Origin will lie to you. ### CEVD-05 — Prove the store (SmartView / Log Server) 03:00 · P3. Helpdesk connected SmartConsole to the SMS, opened Logs, saw nothing, typed “Check Point is down.” The toast from 01:18 is still in the screenshot pack. First tool: confirm where the gateway sends logs (Understanding Logging: Management Server, dedicated Log Server, or local). Then open https://203.0.113.20/smartview/ (lab Log Server) or stay in the SMS Logs tab only after you know that tab queries every Log Server. Proof field: the same Action + Rule + Origin row, now visible on the server that indexed it. Official note: SmartView and SmartConsole Default Time Frames are not synchronized — do not export “last 15 minutes” from one and argue with “last 7 days” from the other. Close I would leave policy alone. I would paste the SmartView URL + the three fields. Empty SMS Logs plus a live fw stat is a store problem or a forwarding problem — not “the firewall is down.” ## 7. Traps + close-the-ticket proof Proof · named field, then Closed Notice: the close is a named column on a timestamp, not a screenshot of the Install Policy toast. You see Weak close Strong close Green Install Policy toast “Check Point is working” fw stat POLICY + DATE on ACTIVE fw stat DATE is old A new Accept at the top Quote DATE; reinstall / fix FWD on that member Logs Action = Drop, Rule = Cleanup Second Any-Any Quote Action + Rule + Origin; change that rule Action = Prevent “Access is broken” Threat Prevention / DLP — not a new Accept Action = Reject “The app is down” Official: gateway notified with TCP RST. Quote Reject. Empty Logs, user still fails Any-Any “to get a log” zdebug drop reason, then stop the debug Alert / reason Address spoofing Missing Accept Topology / Anti-Spoofing on that Interface. Rule 0 is not cleanup. Cluster object green, SSH .12 “ClusterXL is down” cphaprob State = STANDBY; retest ACTIVE SMS Logs empty, fw stat live “The firewall is down” SmartView / dedicated Log Server Accept in Access, still fails “Firewall cannot be the cause” Accept is permission to inspect. Read blade Action / NAT next. Proof checklist before you leave the bridge - UTC window written next to the tool you opened. - Member proved: cphaprob state State on the box you used. - Install proved when the ticket is “is it working?”: fw stat POLICY + DATE (or cpstat -f policy fw ). - One transaction quoted: Logs Action + Rule + Origin , or one zdebug drop reason (debug stopped), or SmartView on the real Log Server. - Interface + TCP flags attached when the reason is spoof or out-of-state. - Next tool named — or change-control owner named. No Any-Any without residual control. Interview close I name the question, then the first tool, then one official field. fw stat proves the install. Logs prove the 5-tuple. fw ctl zdebug drop proves a silent kernel drop. cphaprob state proves the member. SmartView on the Log Server proves the store. I do not change topology, the rulebase, or ClusterXL until that field is on the ticket. Factory model: the SMS toast is not the gateway . ## Knowledge check Six night-shift judgments. Each maps to a first tool or a proof field. Check answers, then Reset if you picked the wrong surface. Q1 01:40. “Is Check Point even working?” Install Policy just toasted green. You have not opened the rulebase. First proof? Add Any-Any at the top of Standard and reinstall On the ACTIVE member run fw stat — quote POLICY + DATE (or cpstat -f policy fw Policy name + Install time) Disable Threat Prevention for the cluster Paste the SMS toast into the ticket and close Correct: b . Official fw stat columns are the installed policy name and the date of the last policy installation. The toast is the SMS. Re-read Side A step 2 and CEVD-01. Q2 A cleanup change shipped an hour ago. One finance host cannot reach SaaS on tcp/443. Which proof field closes CEVD-02? Logs (or fw log): Action + Rule + Origin on that 5-tuple Cluster Mode string only The Install Policy dialog screenshot SmartView User Preferences time frame, with no row Correct: a . Official Logs filters include Action, Rule, Origin. Cluster Mode is membership, not a verdict. Re-read Side B steps 2–3 and CEVD-02. Q3 The same 5-tuple still fails. The Logs query is empty. Track on the suspected rule is None. First tool + field? Add Any-Any so a log appears Declare the gateway down from the empty SMS tab Short fw ctl zdebug drop on ACTIVE — quote the drop reason, then stop the debug cphastop to force a failover and hope a log shows up Correct: c . sk167457 is the official drop viewer when the indexer has nothing. It is a live debug — short window. Re-read Side A step 4 and CEVD-03. Q4 You SSHed 192.0.2.12 because it answered. Connections look empty. The cluster object in SmartConsole is green. First tool + proof? Install Policy again on a single member to “wake it” cphaprob state (or show cluster state): quote member State — STANDBY does not forward in HA Active Up fw ctl zdebug drop left running overnight Add Any-Any because the member you are on has no user logs Correct: b . Official State table: STANDBY waits for Active to fail. Empty tables on STANDBY are expected. Re-read Side A step 1 and CEVD-04. Q5 fw stat DATE matches the change window. SmartConsole connected to the SMS shows no rows. What do you do first? Unload local policy so traffic bypasses the gateway Disable Anti-Spoofing on all interfaces Reboot both members to flush logs to the SMS Leave policy alone. Open SmartView on the dedicated Log Server (or the Logs tab that sees all Log Servers) and quote Action + Rule + Origin there Correct: d . Official: logs may live on a dedicated Log Server; SmartView is https://<Server IP>/smartview/. Empty SMS is not “down.” Re-read Side B step 4 and CEVD-05. Q6 fw stat DATE is yesterday. The Install Policy toast from 01:18 is in the channel. What is that DATE allowed to mean? This gateway did not take tonight’s package — do not hunt a new Access rule first; reinstall / fix FWD on this member, then re-read fw stat Threat Prevention Prevented the toast ClusterXL State is automatically DOWN SmartView User Preferences overwrote the policy Correct: a . Official fw stat DATE is last policy installation on that Security Gateway. The toast is the management plane. Re-read Flow 2 bottom box and CEVD-01.
