A penetration testing method that simulates real-world cyberattacks. This activity helps organizations proactively detect and remediate up to 93% of hidden vulnerabilities, while serving as a core tool to meet the strict compliance requirements of the 2025 Cybersecurity Law before it officially takes effect.
In the digital era, as the enterprise attack surface constantly expands across web applications, mobile devices, and cloud infrastructure, relying solely on passive firewalls is entirely insufficient. To ensure absolute safety for core data assets, administrators must clearly understand what is pentesting and how to deploy it effectively.
This is essentially a "fire drill" conducted by cybersecurity experts to pinpoint weaknesses before cybercriminals actually exploit them. This article comprehensively decodes the concepts, international standard execution processes, and particularly the vital importance of pentesting in meeting the newest legal frameworks.
What is Pentesting and what is the core difference compared to Vulnerability Assessment?
Answering what is pentesting, it is a proactive cybersecurity testing method where experts (white-hat hackers) use real-world attack techniques to exploit systems. The biggest difference is that pentesting digs deep to prove the actual impact of a weakness, whereas Vulnerability Assessment (VA) only passively scans the breadth.
Many organizations frequently confuse these two concepts, leading to critical mistakes in budget allocation strategies. Vulnerability scanning can be likened to a routine general health check-up to list symptoms, while penetration testing is akin to a "stress test" aimed directly at the most vulnerable components.
According to cybersecurity standards from SentinelOne, the core differences between these two methods are clearly demonstrated through operational criteria:
Table: Comparison between Penetration Testing (Pentest) and Vulnerability Assessment (VA)
Criteria | Vulnerability Assessment (VA) | Penetration Testing (Pentest) |
Core Nature | Broad scanning (Breadth) to find known flaws like missing patches or misconfigurations. | Deep diving (Depth) to prove exactly what hackers can achieve with those vulnerabilities. |
Level of Automation | Maximum. Relies heavily on the databases of automated scanning tools. | Combines automated tools with the creative mindset of experts to construct complex exploit chains. |
Output | A list of technical flaws accompanied by severity scores (CVSS). | A detailed report on the intrusion methodology, stolen data, and actual business impact risks. |
Execution Frequency | Frequently (Weekly/Monthly) to maintain basic cyber hygiene. | Periodically (Annually) or following major upgrades and architectural changes. |
What are the benefits of Pentesting for businesses and its role in complying with the 2025 Cybersecurity Law?
Thoroughly understanding what is pentesting helps enterprises exploit dual benefits: simultaneously preventing massive financial losses due to data breaches, and directly meeting the mandatory cybersecurity inspection standards under the 2025 Cybersecurity Law (Law No. 116/2025/QH15).
From a business operations perspective, pentesting is a strategic investment that yields a clear Return on Investment (ROI). By pinpointing the exact attack chains that could occur, pentesting helps optimize the Information Technology (IT) budget, ending the scattered investment in ineffective security tools. Concurrently, proving that the system is periodically tested will strengthen the trust of customers and partners, safeguarding the brand reputation from communication crises caused by data leaks.
Specifically, from a legal standpoint, the introduction of the 2025 Cybersecurity Law (officially effective from July 1, 2026) imposes unprecedented compliance pressure. Deploying Pentests directly resolves the following legal hotspots:
Fulfilling cybersecurity inspection requirements (Article 12): The law mandates that information systems of agencies and organizations must be periodically inspected to detect and remove malicious software, remediate security vulnerabilities, and prevent incidents. Pentesting is the most robust due diligence method for this activity.
Ensuring data security (Article 26): Applying technical measures to prevent data security breaches is strictly mandatory. Pentest reports provide irrefutable evidence to regulatory bodies that the organization has proactively implemented rigorous risk prevention measures.
Avoiding severe sanctions: The law requires handling violating information within a maximum of 24 hours, or 6 hours in emergency cases. Without Pentesting to drill and evaluate the Incident Response capabilities of the technical team, enterprises easily fall into delays, facing the high risk of service suspension on the national cyberspace.
What approaches define the depth of a Penetration test?
The depth of a Penetration test is determined by the amount of initial information provided to the experts, categorized into 3 main approaches: Black box, White box, and Grey box. Selecting the correct method enables organizations to accurately simulate risk scenarios originating from both external and internal sources.
Based on guidelines from security experts, each approach provides a completely different perspective on the system's defensive structure:
Black box testing: Experts are not provided with any internal information other than the IP address or domain name. This method most authentically reflects the perspective of an anonymous hacker attempting to breach defensive barriers from the Internet. This process typically demands significant time for the intelligence reconnaissance phase.
White box testing: Experts are granted full access to system information, including source code, network diagrams, and administrative accounts. This approach helps uncover deeply hidden business logic flaws that external scanning tools can never reach.
Grey box testing: This is a perfect blend of the two methods above. Experts are given limited information, such as a low-level user account. The objective is to evaluate whether a malicious internal employee or a compromised account can escalate privileges to sabotage core systems.
What are the most common types of pentests today to protect systems?
To comprehensively protect the attack surface, organizations are deploying the 5 most common types of testing, including: Web applications, network infrastructure, mobile applications, Application Programming Interfaces (APIs), and Social Engineering. Each type requires a specialized set of tools and exploitation mindset.
Because the IT ecosystem is highly diverse, there is no single testing formula applicable to all infrastructures. Experts must flexibly adapt techniques based on the specific target:
Web application Pentest: Targets browsers and online portals directly. Experts will search for critical flaws listed in the OWASP Testing Guide such as SQL Injection, Cross-Site Scripting (XSS), or authentication vulnerabilities.
Network Pentest: Analyzes internal and external networks to identify weaknesses in firewalls, routers, switches, and transmission protocols lacking encryption.
API Pentest: Evaluates the endpoints communicating between software applications. The goal is to detect authorization flaws (BOLA/IDOR), incorrect privilege assignments, and Rate limiting manipulations.
Social engineering: Simulates deceptive email campaigns (Phishing) impersonating superiors or partners to trick employees into clicking malicious links, thereby testing the security policy compliance level of the entire workforce.
What phases does the international standard Penetration testing process include?
An international standard penetration testing process strictly adheres to regulatory frameworks like NIST SP 800-115 or the Penetration Testing Execution Standard (PTES), advancing through 5 core phases: Planning, Reconnaissance, Exploitation, Privilege Escalation, and Reporting. This rigorous process ensures the integrity of the target system without disrupting business operations.
For a drill to achieve maximum efficiency while remaining safe for live data, the execution steps must be strictly controlled:
Planning & reconnaissance: Establishing the Scope and Rules of Engagement. Subsequently, experts conduct Open Source Intelligence (OSINT) gathering regarding the network structure, domain names, and employee lists of the organization.
Scanning: Utilizing powerful tools like Nmap or Nessus to scan for open ports, running services, and mapping published Common Vulnerabilities and Exposures (CVE).
Exploitation: Experts conduct actual attacks by injecting malicious code or intercepting data flows to bypass security barriers, thereby creating Proof of Concept (PoC) to confirm the vulnerability is real.
Post-exploitation & lateral movement: After a successful breach, the next objective is "Lateral Movement" to other servers and privilege escalation to Administrator/Root levels to fully control the database.
Reporting & retest: Upon conclusion, the organization receives a detailed report describing the attack chain, risk levels, and remediation solutions. After the IT team patches the flaws, experts conduct a Retest to ensure the vulnerability has been completely eradicated.
