Cyberattacks are becoming more frequent and sophisticated, posing a serious threat to the security and privacy of individuals, businesses, and organizations. According to a report by IBM, the average cost of a data breach in 2020 was $3.86 million, and the average time to identify and contain a breach was 280 days. Moreover, cyberattacks can damage the reputation and trust of a company, as well as expose it to legal and regulatory risks. To protect themselves from cyber threats, more companies are taking proactive measures to strengthen their cybersecurity posture. One of these measures is penetration testing, also known as pen testing or ethical hacking. Penetration testing is a simulated cyberattack on a computer system, performed by authorized security experts, to identify and exploit vulnerabilities that could be exploited by malicious hackers. The purpose of penetration testing is to evaluate the security of a system and provide recommendations for improving it.
How does penetration testing work?
Penetration testing can be performed on various types of systems, such as web applications, networks, servers, APIs, mobile devices, etc. The process of penetration testing can be divided into five stages.
- Planning and reconnaissance: This stage involves defining the scope and goals of the test, such as the systems to be tested, the methods to be used, and the expected outcomes. It also involves gathering information about the target system, such as its architecture, functionality, technologies, etc.
- Scanning: This stage involves analyzing the target system to understand how it responds to different inputs and attacks. This can be done using static analysis tools that inspect the code of the system, or dynamic analysis tools that interact with the system in real time.
- Gaining access: This stage involves launching various attacks on the target system, such as cross-site scripting (XSS), SQL injection, brute force, etc., to exploit its vulnerabilities and gain unauthorized access to its data or functionality. The testers then try to escalate their privileges, steal sensitive information, compromise other systems, etc., to measure the impact of the attack.
- Maintaining access: This stage involves trying to maintain a persistent presence in the compromised system, by installing backdoors, malware, or other tools that allow remote access. The testers also try to avoid detection by hiding their tracks or evading security controls. The goal of this stage is to simulate advanced persistent threats (APTs), which are stealthy and long-term attacks that aim to extract valuable data from a system over time.
- Analysis: This stage involves reporting and documenting the findings of the test, such as the vulnerabilities exploited, the data accessed, the duration of the attack, etc. The testers also provide recommendations for fixing the vulnerabilities and enhancing the security of the system.
What are the benefits of penetration testing?
Penetration testing can provide several benefits for a company that wants to improve its cybersecurity, such as:
- Identifying and prioritizing security risks: Penetration testing can reveal the most critical and realistic vulnerabilities in a system that could be exploited by real hackers. This can help a company prioritize its security efforts and allocate its resources accordingly.
- Validating and improving security controls: Penetration testing can test the effectiveness and performance of existing security controls, such as firewalls, antivirus software, encryption, etc., and identify any gaps or weaknesses in them. This can help a company improve its security policies and procedures and implement new or updated controls.
- Demonstrating compliance and trust: Penetration testing can help a company demonstrate its compliance with various security standards and regulations, such as PCI DSS, HIPAA, GDPR, etc., and avoid potential fines or penalties. It can also help a company build trust and confidence with its customers, partners, investors, etc., by showing its commitment to protecting their data and privacy.
- Increasing awareness and education: Penetration testing can increase the awareness and education of a company’s employees, managers, stakeholders, etc., about the importance and challenges of cybersecurity. It can also help them learn from the mistakes and best practices of the testers and adopt a more security-conscious culture.
How often should penetration testing be done?
There is no definitive answer to how often penetration testing should be done, as it depends on various factors such as:
- The type and complexity of the system: Some systems may be more complex or dynamic than others, requiring more frequent or comprehensive testing.
- The level of risk exposure: Some systems may be more exposed or attractive to hackers than others, due to their nature or value of their data.
- The changes in the environment: Some systems may undergo changes in their configuration, functionality, technology, etc., due to updates, upgrades, patches, etc., which may introduce new vulnerabilities or affect existing ones.
- The regulatory requirements: Some systems may be subject to specific security standards or regulations that mandate a certain frequency or scope of testing.
As a general rule of thumb, penetration testing should be done at least once a year, or whenever there is a significant change in the system or the environment. However, it is advisable to consult with a professional penetration testing service provider to determine the optimal frequency and scope of testing for your system.
