# Types of Penetration Testing

**URL:** https://securesys.com.tr/en/learning/penetration-testing/types-of-penetration-testing

No two information technology systems share the same architecture, the same risks or the same attack surface. The vulnerabilities found in a web application are entirely different from the weaknesses in a corporate Active Directory infrastructure or the security risks in a mobile application.

There is therefore no such thing as a **one-size-fits-all penetration test**. The organisation's sector, the technologies it uses, its internet-facing systems, its business processes and the regulations it is subject to all have a direct bearing on the scope of the test.

A professional engagement answers not only the question "which systems will be tested?" but also "which attack scenarios will be applied?". Properly planned work reveals the organisation's real risks while avoiding wasted time and cost.

Below are the most widely applied types of penetration test in use today.

### Web Application Penetration Testing

### VoIP (IP Telephony) Penetration Testing Service

VoIP (Voice over IP) systems are critical communications infrastructure, carrying an organisation's voice traffic over IP networks. VoIP infrastructure containing vulnerabilities can lead to serious risks: unauthorised call access, eavesdropping, account takeover, toll fraud, service outages and corporate data breaches.

The **SecureSys VoIP Penetration Testing Service** assesses your IP telephony infrastructure from a genuine attacker's perspective, measuring its security level, identifying weaknesses and verifying that your communications infrastructure meets international security standards.

SIP servers, IP PBX systems, IP handsets, the VoIP network infrastructure, voice traffic, authentication mechanisms and management interfaces are all analysed comprehensively during testing. The vulnerabilities identified are verified and reported in detail, together with remediation recommendations that can be put into practice.

#### Service Scope

- SIP (Session Initiation Protocol) security testing
- IP PBX security analysis
- VoIP server security testing
- IP handset security analysis
- SIP authentication and authorisation checks
- SIP registration hijacking testing
- SIP enumeration analysis
- Toll fraud risk analysis
- Voice traffic eavesdropping scenarios
- RTP / SRTP security analysis
- TLS configuration checks
- Default password and account security checks
- Management panel security analysis
- Voicemail security testing
- DoS and DDoS resilience testing
- VoIP VLAN and network segmentation analysis

#### Test Methodology

VoIP penetration tests carried out by SecureSys follow these international standards:

- NIST SP 800-58 (Security Considerations for Voice over IP Systems)
- NIST SP 800-115
- PTES (Penetration Testing Execution Standard)
- OWASP Testing Guide (management interfaces)
- CIS Controls
- MITRE ATT&CK Framework

#### Deliverables

VoIP penetration testing simulates realistic attack scenarios in which attackers target IP telephony infrastructure for unauthorised access, call interception, service disruption or system exploitation. Testing assesses not only the technical vulnerabilities but the VoIP architecture, the communication protocols, the access controls and the management processes. The findings are verified, and a practical set of improvement recommendations and a technical action plan are provided to raise the security level of your communications infrastructure.

For the scope of this test, the methodology applied and the deliverables provided, see our [VoIP Security Testing Service](/en/services/voip-security-test-service) page.

### Continuous Vulnerability Assessment Service

Cyber threats and vulnerabilities change constantly, and new weaknesses emerge every day. Security testing carried out once a year is often not enough to keep track of an organisation's changing attack surface.

The **SecureSys Continuous Vulnerability Assessment Service** scans your internet-facing and internal systems at set intervals, automatically and with expert verification, identifying newly emerged vulnerabilities at an early stage. Critical weaknesses can therefore be closed before attackers exploit them.

Servers, network devices, operating systems, web applications, services and other IT assets are monitored continuously; new vulnerabilities are analysed regularly and delivered to you in prioritised reports.

#### Service Scope

- Continuous [vulnerability scanning](/en/services/cyber-security-software)
- Security analysis of internet-facing systems
- Security scanning of internal network assets
- Operating system security analysis
- Server and service security scanning
- Web application vulnerability analysis
- API security scanning
- Network device security analysis
- Misconfiguration detection
- Security patch status analysis
- CVE-based vulnerability detection
- SSL/TLS configuration checks
- Security header analysis
- Asset inventory and attack surface monitoring
- Automatic detection of newly added systems
- Risk prioritisation and trend analysis
- Reduction of false positives through expert verification

#### Test Methodology

Continuous vulnerability assessment carried out by SecureSys follows these international standards:

- CVSS v3.1 (Common Vulnerability Scoring System)
- CVE (Common Vulnerabilities and Exposures)
- CWE (Common Weakness Enumeration)
- NIST National Vulnerability Database (NVD)
- NIST SP 800-40 (Patch Management)
- CIS Controls
- PTES (Penetration Testing Execution Standard)

#### Deliverables

- Executive Summary
- Continuous vulnerability assessment reports
- Critical / High / Medium / Low risk distribution
- CVE and CVSS-based risk analysis
- List of affected systems and assets
- Trend and comparative security reports
- Remediation priority list
- Technical improvement recommendations
- Management panel and dashboard access
- Periodic executive presentations

#### Benefits

- Newly emerged vulnerabilities are identified early
- The attack surface is reduced through continuous visibility
- Critical weaknesses are prioritised and closed quickly
- The effectiveness of patch management processes is improved
- Misconfiguration is checked regularly
- The development of the security level over time can be tracked
- Compliance work for ISO/IEC 27001, KVKK, PCI DSS, DORA and NIST requirements is supported
- Cyber risk is reduced through a proactive security approach

The Continuous Vulnerability Assessment Service analyses your IT infrastructure at set intervals using automated methods with expert verification, monitoring new vulnerabilities, misconfiguration and risk on an ongoing basis. Weaknesses are therefore identified before attackers exploit them, prioritised, and reported together with improvement recommendations that can be put into practice — raising the organisation's cyber resilience continuously.

### Which Penetration Test Is Right for Your Organisation?

Every organisation needs a different scope.

For an e-commerce company the priority may be web application and API security; in a manufacturing plant the OT/ICS systems may be more critical. In the financial sector Active Directory and internet-facing systems come to the fore, while for a technology company offering SaaS, cloud security and API testing matter more.

A successful penetration test is therefore planned not from an off-the-shelf checklist but around the organisation's assets, its threat model and its business processes.

The systems tested are not the only thing determining whether a penetration test succeeds. **The scope of the test and the perspective it takes** matter every bit as much.

**So how is scope determined when a penetration test is planned? Which IP addresses, applications, user roles and systems are included? How are the boundaries drawn, and why does good planning matter so much?**
