Every Indian enterprise IT leader knows about perimeter firewalls, endpoint protection, and SIEM dashboards. Yet over the past two years, a quieter attack surface has been responsible for some of the most damaging breaches globally — and increasingly across South Asia. That surface is your Application Programming Interface (API) layer.
APIs are the connective tissue of the modern enterprise. Banking apps, insurance portals, ERP integrations, B2B partner feeds, mobile applications — all rely on APIs to transfer data between systems. That makes them enormously valuable to attackers. Compromising one API can expose customer PII, financial records, and internal business logic in a single transaction, often without triggering a single firewall alert.
This post explains why API security deserves its own place on your risk register, how Indian regulatory obligations under the DPDP Act and CERT-In directives apply, and what a layered, SOC-visible API security posture looks like in practice.
Traditional attacks targeted the network perimeter: they scanned ports, exploited unpatched OS vulnerabilities, or phished employees for credentials. Modern attackers are more surgical. They target APIs because:
OWASP’s API Security Top 10 (2023 edition) catalogues the most exploited weakness categories: broken object-level authorisation (BOLA), authentication flaws, unrestricted resource consumption, and mass assignment, among others. Every one of these requires application-aware detection, not just packet inspection.
Two Indian regulatory frameworks directly touch API security in ways that organisations may not have fully mapped.
If your API serves, receives, or routes personal data of Indian citizens — which virtually every customer-facing API does — you are processing data under the DPDP Act. The Act requires “reasonable security safeguards” to prevent data breaches. An API that leaks customer records through a BOLA flaw or an unauthenticated endpoint is a direct compliance exposure. When a breach occurs, the Data Protection Board can levy financial penalties on data fiduciaries. Regulators will ask: was this API inventoried, tested, and monitored? API security documentation becomes audit evidence.
The Ministry of Electronics and IT’s 2022 directions require Indian organisations to report cybersecurity incidents to CERT-In within six hours of becoming aware. An API breach — especially one involving data exfiltration — is a reportable incident. Two obligations flow from this:
Both of these obligations reinforce the same underlying need: real-time API observability with durable, compliant log retention.
Securing APIs is not a single-product problem. It requires controls at multiple layers.
You cannot protect what you cannot see. The first step is a complete API inventory: all endpoints, authentication methods, data types handled, and owner teams. Automated discovery tools — integrated into your application delivery infrastructure — continuously scan for shadow and zombie APIs that may have been missed.
At PJ Networks, we begin API security engagements with a discovery exercise that frequently uncovers endpoints that internal teams did not know were still active.
A properly configured FortiGate Next-Generation Firewall with Web Application Firewall (WAF) capabilities provides the first line of defence for published APIs. Rate limiting per client and per endpoint caps brute-force and scraping attacks. TLS inspection ensures that encrypted API traffic is not used as a blind channel. Geo-IP policies restrict access from regions with no legitimate user base.
FortiGate’s integration with FortiGuard Threat Intelligence feeds means that known malicious IPs, Tor exit nodes, and scanner fingerprints are blocked before they reach your API layer.
The most common API vulnerability class — BOLA — exists because APIs return any object whose ID is guessed, regardless of whether the requesting user is authorised to see it. Fixing this is an application-level control, but the SOC must be able to detect when mass horizontal enumeration is occurring.
Strong authentication — short-lived JWT tokens, mutual TLS for partner APIs, and FIDO2 for human-facing API flows — reduces the blast radius of stolen credentials. Zero Trust Network Access (ZTNA) architecture, as deployed by PJ Networks through FortiZTNA, ensures that API consumers are continuously re-validated rather than trusted on the basis of a session established hours earlier.
This is where SOC visibility becomes critical. A baseline of normal API behaviour — typical call volumes, parameter ranges, response sizes, geographic sources — allows anomaly detection to flag deviations that signature-based tools miss. Machine-learning models trained on your specific API traffic patterns are far more effective than generic rules.
Integrating API gateway logs, FortiGate traffic logs, and application event data into your SIEM gives analysts a unified view. When an API key suddenly starts making calls at 3 AM from an unrecognised ASN, the SOC sees it in minutes, not days.
Long-term API security requires embedding security practices into the development and release pipeline: API specification reviews, automated security testing in CI/CD, and secure coding standards for authentication and input validation. PJ Networks works with enterprise development and platform teams to operationalise these controls alongside SOC-facing detection.
Mature SOCs use MITRE ATT&CK to structure detection coverage. API attacks map clearly to this framework:
Detection rules mapped to these ATT&CK techniques, correlated with API-layer telemetry, allow SOC analysts to build attack storylines rather than investigating isolated alerts.
Detecting API attacks at scale requires a platform that can ingest high-volume API telemetry, correlate it across sources, and drive rapid response — all while meeting CERT-In’s retention and reporting obligations. PrahiX Ora is the unified SecOps platform that PJ Networks deploys and operates for enterprise clients.
SIEM — Correlated Visibility Across the API Stack: Ora’s SIEM ingests logs from API gateways, FortiGate firewall sessions, web application proxies, and application servers into a single correlation engine. Detection rules are mapped to MITRE ATT&CK techniques, so an API enumeration attack surfaces as a named technique rather than a raw log anomaly. Graph-based attack storyline reconstruction links the initial reconnaissance scan to the credential stuffing attempt to the eventual data pull — giving analysts the full picture, not disconnected alerts. Tiered hot/cold/archive retention supports CERT-In’s direction on 180-day in-country log retention, keeping investigation data accessible without ballooning storage costs.
NMS — Network Context for API Traffic: API traffic does not exist in isolation. Ora’s Network Management System provides unified observability across FortiGate firewalls, switches, wireless APs, and SD-WAN links using LLDP/CDP topology discovery. When an anomalous API call pattern emerges, SOC analysts can immediately trace the network path — from which interface the traffic entered, through which segments it transited — and correlate it with network-level anomalies flagged by ML-based detection. In multi-vendor environments, where NOC visibility is often fragmented across vendor-specific consoles, this unified topology view is operationally significant.
Video Surveillance (VMS) — Physical and Digital in One Operations View: For manufacturing, retail, and multi-site organisations, physical security events can correlate with digital attacks. Ora’s video surveillance (VMS) capability manages ONVIF, Hikvision, and Dahua cameras with video analytics from the same operations console as network and security monitoring. An unauthorised physical access event at a data centre can be correlated with a simultaneous spike in privileged API calls — a connection that siloed systems would miss.
SOAR — Closing the Six-Hour Reporting Window: CERT-In’s six-hour incident reporting requirement is achievable with automation, but challenging with manual processes alone. Ora’s SOAR module provides pre-built playbooks and automated response actions including pushing blocklists directly to FortiGate. When an API key is identified as compromised, automated revocation, customer notification initiation, and CERT-In incident log generation can all begin within minutes of detection — making the six-hour window realistic rather than aspirational. PJ Networks’ 24/7 SOC team operates and fine-tunes these playbooks to reduce false positives and ensure analyst-approved actions.
If your organisation is dealing with fragmented API visibility or struggling to meet CERT-In’s reporting timeline, we are happy to walk you through how the platform operates in practice.
Across our engagements with Indian enterprise and mid-market organisations, a consistent set of gaps recurs:
If you are beginning to formalise API security, the following sequence is effective:
APIs are not an emerging risk — they are a current one. Indian enterprises that have invested in perimeter security, endpoint protection, and SOC operations need to ensure that API-layer visibility is not the missing piece in their security architecture. The DPDP Act and CERT-In’s reporting requirements make this a regulatory obligation as well as a security necessity.
PJ Networks helps Indian enterprises design, deploy, and operate API security controls across FortiGate WAF/NGFW, ZTNA, and the PrahiX Ora SecOps platform. Our 24/7 NOC/SOC team provides the continuous monitoring that makes API attack detection operational rather than theoretical.
