Question 151: 

What functionality does FortiGate web proxy caching provide for performance optimization?

A) No caching capabilities

B) Content caching reducing bandwidth consumption and improving response times

C) Blocking all cached content

D) Removing proxy features

Correct Answer: B

Explanation:

Web proxy caching stores frequently accessed content locally reducing bandwidth consumption and improving user response times through local content delivery. FortiGate web proxy caching capabilities maintain caches of web objects, images, scripts, and other cacheable content serving subsequent requests from local storage without requiring origin server retrieval. The caching proves particularly valuable for bandwidth-constrained environments or geographically distributed users accessing common content where local cache delivery substantially improves performance.

Content caching stores HTTP responses meeting cacheability criteria. Cache-Control headers indicate content cache eligibility specifying freshness durations. Static content including images, stylesheets, and JavaScript files represent ideal caching candidates with extended validity periods. Dynamic content with appropriate caching headers receives time-limited caching. The intelligent caching respects origin server directives ensuring served content remains appropriately fresh.

Cache hierarchy support enables multi-tier caching architectures. Branch office proxies cache locally while utilizing regional or central caches for cache misses. The hierarchical approach optimizes bandwidth across distributed networks reducing redundant downloads across multiple locations. Parent cache relationships define cache request forwarding when local caches lack requested content.

Bandwidth savings result from eliminating redundant content transfers. Popular content accessed by multiple users downloads once then serves from cache for subsequent requests. The bandwidth conservation proves valuable for expensive WAN links or metered internet connections. Organizations with hundreds of users accessing identical content achieve substantial bandwidth reductions through effective caching.

Response time improvements derive from local content delivery eliminating network latency. Cache hits return content within milliseconds compared to hundreds of milliseconds for internet round trips. The performance enhancement improves user experience particularly for high-latency connections. Media-rich websites with numerous images benefit substantially from caching.

Cache size configuration balances storage capacity against hit rates. Larger caches retain more content improving hit rates but consuming more storage. Intelligent eviction policies remove least-recently-used content when cache capacity fills. The size optimization ensures cache provides maximum benefit within available resources.

Negative caching prevents repeated requests for non-existent resources. Failed requests receive short-duration negative caching preventing redundant failed requests for temporarily unavailable content. The negative caching reduces unnecessary traffic for missing resources.

Cache bypass capabilities exclude specific content from caching. Dynamic authenticated content requires bypass preventing inappropriate content sharing between users. Transactional content unsuitable for caching receives bypass. Configurable bypass rules accommodate diverse content caching appropriateness.

Question 152: 

Which FortiGate mechanism provides protection against man-in-the-middle attacks?

A) No MITM protection

B) Certificate validation with pinning support and anomaly detection

The validation prevents attackers from successfully presenting forged certificates without detection.

Certificate pinning support enables applications validating expected certificates for critical services. Pinning specifies expected certificate characteristics including public keys or certificate hashes. Connections presenting unexpected certificates despite valid CA signatures receive rejection. The pinning provides enhanced protection for high-security applications knowing expected certificate attributes.

SSL version enforcement prevents downgrade attacks forcing legacy SSL versions with known vulnerabilities. Minimum TLS version requirements ensure modern secure protocols. Weak cipher suite blocking prevents cryptographically weak encryption negotiation. The protocol security ensures strong cryptography resistant to cryptanalytic attacks.

Certificate transparency monitoring examines certificate issuance through public CT logs. Unexpected certificate issuance for organizational domains suggests compromise or unauthorized certificate acquisition. The CT monitoring provides early warning of potential MITM preparation through unauthorized certificate obtaining.

Anomaly detection identifies suspicious SSL behaviors suggesting interception attempts. Certificate changes for previously known sites warrant investigation. Unexpected certificate authorities for major services suggest interception. Self-signed certificate appearances for normally CA-signed sites indicate potential MITM. The behavioral detection complements validation providing additional indicators.

HSTS enforcement prevents SSL stripping attacks downgrading HTTPS to HTTP. Strict Transport Security headers enforce HTTPS usage preventing protocol downgrade. HSTS preload list integration enforces HTTPS for known HSTS-enabled sites. The enforcement maintains encryption preventing cleartext exposure through downgrade attacks.

Public key pinning validates expected public keys for critical sites. Browser-based pinning validates server public keys against expected values. Unexpected key changes suggest certificate substitution attempts. The key-level validation provides granular certificate verification beyond CA trust validation.

Question 153:

FortiGate DLP watermarking capabilities insert visible or invisible watermarks containing user identity, timestamp, document classification, or organization information. The watermarking provides accountability and investigation support when sensitive documents leak identifying responsible parties or leak channels supporting insider threat investigations and external breach analysis.

Visible watermarking applies conspicuous markings to document content. Headers, footers, or background text display user names, classifications, or warnings. The visible markings deter unauthorized disclosure reminding users of document sensitivity. Screenshot captures retain watermarks maintaining attribution through informal sharing. The psychological deterrent effect prevents some intentional leaks while providing attribution for leaks that occur.

Invisible watermarking embeds hidden information undetectable through casual inspection. Digital watermarks encode data within document structures or content using steganographic techniques. The hidden watermarks survive format conversions and electronic transmission. Forensic analysis extracts embedded information from leaked documents. The covert approach prevents watermark removal while maintaining full attribution capability.

User attribution watermarks identify document recipients uniquely. Individual user identifiers embedded in watermarks enable leak source determination. Multiple recipients receiving identical documents with unique watermarks enable distinguishing leak sources through watermark examination. The attribution supports investigation identifying specific users responsible for leaks.

Timestamp watermarking records document access times. Temporal information helps narrow leak timeframes during investigations. Access logs correlation with watermark timestamps validates leak timeline. The temporal attribution provides investigation context identifying when sensitive access occurred.

Classification watermarking embeds document sensitivity levels. Confidential, secret, or proprietary classifications appear in watermarks. The classification reminders reinforce handling requirements. External parties receiving leaked documents understand sensitivity through embedded classifications.

Organization identification watermarks assert document ownership. Company logos, names, or proprietary statements embedded in watermarks establish intellectual property claims. The organizational attribution supports legal actions against unauthorized disclosure or competitive intelligence theft.

Behavioral indicator aggregation combines multiple risk factors into composite scores. Failed authentication attempts increase risk scores. Access to sensitive resources outside normal patterns elevates scores. Unusual application usage contributes to risk assessment. Geographic anomalies including impossible travel scenarios substantially increase scores. The multi-factor assessment provides comprehensive risk evaluation.

Risk score calculation applies weighting to different indicators reflecting relative significance. Critical security events receive heavy weighting substantially impacting scores. Minor anomalies contribute modest score increases. The weighted calculation ensures scores meaningfully reflect actual risk levels rather than treating all indicators equally.

Baseline comparison evaluates current behaviors against established normal patterns. Deviations from baselines increase risk scores proportionally to deviation magnitude. Completely unprecedented behaviors receive maximum score increases. Minor variations cause smaller increases. The baseline-relative assessment accounts for legitimate behavioral variations across user populations.

Temporal analysis considers risk indicator timing and patterns. Clustered suspicious activities within short timeframes suggest coordinated attacks. Isolated anomalies separated by normal behavior periods represent lower risk. The temporal context refines risk assessment improving accuracy.

Risk score persistence implements decay reducing scores over time when suspicious activities cease. Recent indicators contribute more heavily than historical events. The decay prevents permanent high scores from isolated incidents enabling score recovery as behaviors normalize.
