Cisco 300-725 SWSA study plan
Cisco 300-725 SWSA · Give each week a clear focus.
8 weeks · About 7 hours per week
Describe the Cisco Web Security Appliance (WSA) architecture and deployment options & Configure and verify proxy and transparent traffic redirection
Diagram the WSA data path from the client-side NIC through the proxy engine to the upstream NIC, labeling where transparent redirection, authentication, access policy, and scanning occur.
Compare explicit proxy, transparent proxy via WCCP, and transparent proxy via PBR/L4 redirection, listing which client and network prerequisites each requires.
Configure a WSA network interface pair (M1/P1) with correct routes and DNS, then verify connectivity with the built-in network diagnostic tools.
Build a packet-flow checklist that distinguishes how the WSA handles an explicit HTTP request versus a transparently redirected HTTPS connection.
Your checkpoint
A one-page architecture and redirection diagram plus a written comparison table of explicit, WCCP, and PBR deployment models with prerequisites and failure behavior for each.
Configure and verify proxy and transparent traffic redirection & Configure authentication, identity, and access policies
Configure an explicit HTTP proxy listener and confirm a test client reaches the internet through it, then capture traffic to show the proxy hop.
Configure transparent redirection for HTTP and HTTPS and verify that client browsers with no proxy settings still traverse the WSA.
Configure an authentication realm (LDAP or Active Directory) with a bind account and test user lookup against a directory.
Configure an identd or transparent authentication method and verify that a client IP maps to a username in the access logs.
Your checkpoint
A working lab where one explicit client and one transparent client both authenticate against the directory, evidenced by access log entries showing distinct usernames for each client IP.
Configure authentication, identity, and access policies & Configure and verify web usage controls and Acceptable Use Policies
Write an access policy with identity-based and URL-category conditions, order the rules correctly, and verify the first-match behavior with test traffic.
Configure URL filtering categories and a custom URL category, then verify allow and block outcomes against the policy.
Configure an Acceptable Use Policy enforcement path, including a block page with custom messaging and a time-based or quota-based restriction.
Configure application-level controls (for example, bandwidth limits or application visibility) and verify the effect on test traffic.
Your checkpoint
A policy matrix document mapping each test user and URL category to the expected action, with log evidence confirming every expected allow and block was actually enforced.
Configure and verify anti-malware and advanced threat protection & Configure and verify SSL/TLS inspection and decryption policies
Configure anti-malware scanning with the web reputation and file reputation engines, then verify detection using the built-in test malware URL and confirm the block is logged.
Configure advanced threat protection features (for example, file analysis submission and sandboxing) and verify that a submitted sample appears in the analysis portal.
Configure an HTTPS decryption policy with a certificate authority, deploy the root certificate to a test client, and verify that decrypted traffic is inspected.
Create a decryption exception for a category or domain and verify that exempt traffic bypasses inspection while still being logged.
Your checkpoint
A test-results table showing one blocked malware download, one sandbox submission, one successfully decrypted HTTPS session, and one bypassed decryption exception, each with a matching log entry.
Configure and verify SSL/TLS inspection and decryption policies & Configure and verify anti-malware and advanced threat protection
Troubleshoot a decryption failure by inspecting certificate trust, SNI handling, and the decryption policy match, then document the root cause.
Configure certificate revocation checking and verify behavior when a revocation server is unreachable.
Tune anti-malware and reputation thresholds and verify how a policy change alters the action for a previously allowed file.
Compare decryption policy outcomes for a user in an authenticated identity group versus an unauthenticated guest.
Your checkpoint
A troubleshooting runbook for HTTPS decryption failures listing at least five symptoms, their likely causes, and the exact verification command or log field to confirm each.
Configure and verify data loss prevention and data security policies & Operate, monitor, and troubleshoot the WSA (reporting, logging, upgrades, backups)
Configure a data loss prevention policy with a custom classification (for example, a regex for a national ID or credit card pattern) and verify detection on an outbound upload.
Configure data security controls such as external data transfer limits or file-type restrictions and verify enforcement.
Configure logging to a remote syslog or SIEM target and verify that access, malware, and DLP events arrive.
Schedule and run a configuration backup, then verify the archive can be downloaded and its contents listed.
Your checkpoint
A DLP test report showing one detected outbound upload with the matched classification, plus a successful syslog capture containing at least one access-log, one malware, and one DLP event.
Operate, monitor, and troubleshoot the WSA (reporting, logging, upgrades, backups) & Configure and verify data loss prevention and data security policies
Build a custom report from the reporting engine covering top blocked categories and top malware sources for a test period, and export it.
Trace a single user session end to end using access logs, then correlate it with proxy and DLP logs.
Perform an upgrade path check: identify the current and target AsyncOS versions, review release notes, and stage an upgrade in the lab.
Troubleshoot a simulated proxy failure using packet captures, the CLI diagnostic commands, and service status, and document the resolution.
Your checkpoint
An operations package containing one exported custom report, one end-to-end session trace, and a written upgrade plan with pre-checks, rollback steps, and post-upgrade verification.

Re-run every weekly deliverable against a fresh lab configuration to confirm reproducibility without notes.
Complete timed practice sets weighted toward domains 2, 3, 5, and 6, and review every missed item to its root concept.
Write a one-page cheat sheet covering redirection modes, authentication flows, decryption policy order, and DLP matching logic.
Identify the three weakest objectives from the practice results and rebuild each in the lab until verified.
Your checkpoint
A final readiness scorecard showing practice scores by domain, a completed cheat sheet, and lab evidence for the three remediated weak objectives.
Milestones
Week 2: Both an explicit and a transparent client reach the internet through the WSA, and access logs show a resolved username for each.
Week 4: Malware is blocked, a sample is submitted for analysis, HTTPS traffic is decrypted and inspected, and a decryption exception is confirmed bypassed, all with matching log entries.
Week 6: A DLP policy detects a custom-classification outbound upload, and remote syslog receives access, malware, and DLP events.
Week 8: All eight weekly deliverables are reproducible from a clean configuration, and practice scores exceed 80 percent in every domain with the weakest three remediated in the lab.
