Security Testing: Essence

IT security testing is aimed to detect and analyze security vulnerabilities in software, IT infrastructure, security policies (including access control, communication, incident response, disaster recovery policies etc.) and procedures (user authentication, sensitive data encryption and disposal, etc.). Depending on a company’s specific needs, in-house or outsourced security testing professionals carry out vulnerability assessment, penetration testing, security code review, compliance testing or security audit. Regular security testing is the best practice for a company to ensure compliance with cybersecurity regulations and enhance its IT security posture.

Security Testing Set Up Plan

With many industry- and company-specific considerations, a cybersecurity testing set up plan asks for a case-by-case approach. ScienceSoft has outlined commonly applicable guidelines for an in-house and outsourced IT security checkup, based on our experience in security testing.

1. Security testing planning

Duration: 2-3 weeks.

  • Assigning a security testing manager to plan and oversee the security testing project.
  • Defining the scope of cybersecurity testing: the targets (networks, applications, servers, security software, physical security); the testing types and timeframe. Depending on the testing needs, one or several of the following security testing types may be planned:

Vulnerability assessment

Automated extensive identification, analysis and prioritization of software and IT infrastructure vulnerabilities.

Penetration testing

Detection and in-depth exploration of software and IT infrastructure vulnerabilities and their impact on the company. Simulation of life-like cyberattacks.

Security code review

Analyzing application source code to detect security flaws, such as encryption errors, buffer overflow, XSS and SQL injection vulnerabilities.

Compliance testing

Checking if a company’s information security policies as well as the security controls in software and IT infrastructure meet regulatory standards (PCI DSS, HIPAA, GLBA, GDPR etc.)

Security audit

A full-scale assessment of a company’s cyber defense. IT infrastructure and software security tests along with evaluating the information security policies, security awareness of the staff, physical hardware access.

ScienceSoft’s tip: A company should plan at least 1 penetration test per year and 1 vulnerability assessment per quarter. Ideally, a security test should follow any major change in software and/or IT infrastructure.

  • Estimating the budget of the security testing project.
  • Designing the data handling policy: collecting, storing, sharing, and deleting test data.
  • Planning a mitigation strategy for possible risks related to the IT infrastracture and software security testing (e.g., unintentional data exposure, server or network outages, productivity loss).
  • Optimizing the plan to ensure against redundant efforts and expenses.

2. Security testing preparation

The sourcing model that a company chooses defines the preparation stage.

In-house security testing preparation

Duration: up to 12 weeks if it is necessary to hire and/or train security testing professionals.

  • Building a qualified team knowledgeable about the security techniques and tools to be applied.
  • Holding additional training, if needed.
  • Selecting security the testing approach and techniques: e.g., internal or external, black box, gray box or white box testing, destructive (SQL injections, DDoS attacks, buffer overflow, application level floods, brute-force attacks, etc.) or non-destructive (network mapping, OS fingerprinting, social engineering, network sniffing, vulnerability scanning) techniques.
  • Selecting appropriate open-source or/and commercial security testing tools:

Vulnerability assessment

Host-based, network-based, wireless, application, database scanners.

Penetration testing

Network protocol analyzers, network mapping, password recovery tools, fuzzer, web crawler,dynamic application security testing (DAST), etc.

Security code review

Static application security testing (SAST).

Compliance testing

Sensitive data finders, automated evidence collection tools, compliance scanners.

Security audit

Computer-aided audit tools (CAAT).

  • Deciding if test environment is needed. This can be a reasonable solution if the security testing team applies intrusive techniques that may damage production environment or disrupt critical business activities.
  • Providing the team with the required access to the target assets and data for security test execution.

Vendor selection for outsourced security testing

Duration: up to 12 weeks (to search, study and compare the security testing providers on the market).

Choosing a provider to take over the security testing process in your company, you may be guided by:

  • Credentials and testimonials. Certifications (ISO 9001, ISO 27001, CEH, etc.) and real people reviews serve as tangible quality proof.
  • Portfolio.
  • Security testing team expertise: preferably dedicated specialists skilled in automated and manual techniques.
  • Comprehensive deliverables. Security testing reports must include a sound analysis of identified vulnerabilities and their causes, as well as offer remediation guidance for each finding.

3. Security testing launch and execution

Security testing launch and execution will differ depending on the testing scope and, consequently, on the testing type:

Vulnerability assessment

Duration: 1-2 weeks

  • Running automated scans on the target software, networks or devices to identify existing vulnerabilities.
  • Manual review of scanning results to eliminate false positives.
  • Analyzing detected vulnerabilities and their causes, evaluating their severity.
  • Reporting on the results with recommendations on how to fix the vulnerabilities.

Penetration testing

Duration: 1-3 weeks

  • Vulnerability scanning: identifying exploitable vulnerabilities.
  • Vulnerability exploitation: simulation of true-to-life attacks.
  • Analyzing the exploited vulnerabilities and their impact on compromised software and IT infrastructure, as well as on the company’s business in general.
  • Reporting and remediation guidance.

Security code review

Duration: 1-8 weeks

  • Automated scanning of the application source code.
  • Manual review.
  • Analyzing detected vulnerabilities.
  • Reporting on the findings and recommendations on enhancing application security.

Compliance testing

Duration: up to 10 weeks

  • Running vulnerability scanners, reviewing application source code using penetration testing techniques to find security flaws in software and IT infrastructure.
  • Defining deviations from industry regulatory standards and advising on their mitigation.
  • Report on Compliance and/or Attestation of Compliance.

Security audit

Duration: up to 14 weeks

  • Analyzing security policies and procedures.
  • Interviewing employees to assess their security awareness.
  • Incorporating vulnerability assessment, penetration testing, code review and compliance testing, depending on the audit scope.
  • Examining physical access to hardware.
  • A report with detailed description and analysis of all findings as well as recommendations how to fix revealed security gaps.

  • In-house testers can quickly launch a new security testing project or conduct re-testing after remediation.


  • Security testing skills may be limited.
  • The need to update security testing toolkit and hold training for the testers.
  • Salaries and maintenance cost.

Security testing management and implementation are completely outsourced


  • Solid experience and best practices: a wide choice of advanced cybersecurity testing technologies and skills.
  • Cost effectiveness and reduced TCO.
  • The vendor takes over planning, preparation and implementation of security testing project.
  • An independent expert view: impartial insights into your company’s security policy and infrastructure.


  • It may be complicated to choose a reliable security testing vendor among the multitude of offers on the market.
  • Exposing your IT infrastructure to a third party may be risky, unless you deal with a reliable vendor.
