In the rapidly evolving cyber threat landscape, is becoming paramount to take proactive measures against cyber criminals. One such measure is penetration testing (a.k.a. “pentesting”, “pen-testing” or, sometimes, simply “pentest”), a crucial tool in your cybersecurity arsenal.
From ransomware attacks that lock you out of your own systems, to phishing scams that trick employees into revealing sensitive data, to SQL injection attacks that exploit vulnerabilities in your website or application, the threats are diverse and constantly changing. While traditional security measures like firewalls and antivirus software are important, they can’t keep up with the pace of emerging threats. Pentesting provides a proactive approach to cybersecurity, allowing startups to stay one step ahead of cybercriminals.
Think of pentesting as hiring a friendly hacker who attempts to breach your defenses.
Pentesting simulates cyber attacks on a company’s system to identify vulnerabilities that could be exploited by cybercriminals. Contrary to some beliefs, this practice is not just for mature corporations; it’s equally, if not more, critical for startups that can often face massive consequences from a data breach.
Understanding this involves acknowledging the importance of pentesting, along with its strengths and weaknesses.
Why Your Startup Needs Pentesting
Pentesting is a vital cybersecurity measure that is often overlooked by startups, especially considering that, likely, this activity has never been carried out before.
If pentesting succeeds, there will not be real consequences for your application, customers, or data treasure but any issues found will be reported back to you, offering you a chance to patch up the weak spots before real invaders come. No harm done (and a chance to fix the issues before the real damage happens).
With limited resources and potentially massive consequences from a data breach, startups can’t afford to ignore the power of pentesting.
Another myth is that pentesting is costly and time-consuming. While there is an investment of time and resources, these can be considered the lesser evil, when compared to the cost of a data breach, which can lead to financial losses, reputation damage, and loss of customer trust.
From a business risk point of view, pentesting helps startups to proactively identify and address vulnerabilities, reducing the risk of a costly cyber attack.
To truly understand the power of pentesting, think of your startup as a fortress. Your sensitive data is the treasure, and cybercriminals are the invaders. You’ve put up walls and barricades (your cybersecurity measures), but are they strong enough?
If your pentester succeeds, she won’t steal your treasure but instead report back on how she managed to infiltrate, offering you a chance to patch up the weak spots before real invaders come. It’s a proactive and practical approach to securing your digital assets.
A Typical Pentesting Process
The pentesting process can be broken down into five main stages: planning, scanning, gaining access, maintaining access, and analysis.
- In the planning stage, the scope and goals of the test are defined, and the systems to be tested are identified.
- During scanning, the system is analyzed to identify potential entry points for an attack.
- In the gaining access phase, the pentester attempts to exploit the vulnerabilities identified, just as a hacker would.
- Maintaining access involves seeing if the system vulnerability can be used to achieve sustained access, mimicking advanced persistent threats.
- Finally, in the analysis phase, the pentester compiles a report detailing the vulnerabilities discovered, the data that was at risk, and recommendations for mitigation. This comprehensive process gives a holistic view of your startup’s cyber defenses.
About Ethical Hacking
Ethical hacking, the practice that underpins pentesting, is a powerful protective tool for your startup. Ethical hackers, also known as white hat hackers, use their skills to help, not harm. They employ the same methods as malicious hackers but for a beneficial purpose: to find and fix vulnerabilities before they can be exploited. Through this controlled simulation of a cyber attack, startups can gain a clear understanding of their security posture.
Your actionable insights will allow you to strengthen your startup defenses, ensuring that if (or when) a real attack comes, you are well-equipped to fend it off.
The Cost of Ignoring Pentesting: A Tale of Unfortunate Events
The consequences of neglecting pentesting can be severe. Let’s look at a fictitious company, called HealthStart. They had a promising health-tracking app but overlooked the need for thorough cybersecurity measures, including pentesting. A few months after launch, they suffered a data breach, with thousands of users’ health data being leaked. This resulted in severe reputation damage, loss of customer trust, legal consequences, and significant financial losses. HealthStart serves as a cautionary tale about the importance of pentesting as part of a comprehensive cybersecurity strategy.
Red Team, Blue Team: The Pentesting Actors You Should Know
In the world of pentesting, you may hear the terms ‘Red Team’ and ‘Blue Team’.
Why is pentesting sometimes called a “red teaming exercise”?
- A Red Team is a group of ethical hackers who simulate cyberattacks on an organization. The goal of a Red Team is to expose vulnerabilities and assess the effectiveness of the existing security measures.
- On the other hand, the Blue Team is responsible for defending against these simulated attacks, using their skills to detect and mitigate threats.
These two teams work together in a controlled environment to provide a comprehensive evaluation of a startup’s cybersecurity posture.
Fun fact: sometimes these teams together are also called “purple” as red and blue make this color.
Pentesting Tools
Pentesting involves the use of specialized tools that help ethical hackers carry out their tests. A pentester uses these tools can scan for vulnerabilities, simulate attacks, analyze network traffic, and much more.
Common tools include Nessus for vulnerability scanning, Wireshark for network analysis, and Metasploit for developing and executing exploit code against a remote target machine. While the specific tools used may vary depending on the scope and nature of the pentest, they all serve to provide a detailed and accurate assessment of a system’s vulnerabilities.
Tools aside, real pentesting should go beyond the results of automated tools and would require a human to actually use the information gathered to craft more targeted and “intelligent” attacks.
Types of Pentesting: Which One is Right for Your Startup?
There are several types of pentesting, each with its own focus:
- Network pentesting aims to uncover vulnerabilities in a network’s infrastructure.
- Application pentesting focuses on finding security flaws in software applications.
- Social engineering pentesting tests an organization’s defenses against human manipulation.
- Physical pentesting checks for vulnerabilities in an organization’s physical security.
When you hear the term white-box or black-box pentesting, it simply means whether the red team will have access to inside information (e.g. the source code, if it is for an application) or not. Which one of the two do you think it’s a black-box pentesting?
The right type of pentesting for your startup depends on your specific circumstances, such as your business model, the nature of your data, your infrastructure, and the threats you’re most likely to face.
Pentesting and Regulatory Compliance: A Mandatory Duo
Pentesting is not just a security best practice; it’s also often a regulatory requirement. Compliance standards like the Payment Card Industry Data Security Standard (PCI DSS) and the Health Insurance Portability and Accountability Act (HIPAA) require regular pentesting.
Remember that non-compliance can lead to penalties and can also impact your startup’s reputation. By incorporating pentesting into your security strategy, you demonstrate a commitment to safeguarding sensitive data and building trust with customers, partners, and stakeholders.
Making the Most of Your Pentest: Post-Test Actions
A pentest provides valuable insights, but its true value is realized only when those insights are acted upon. Once vulnerabilities have been identified, the next step is to address them. This might involve patching software, tightening network security, training staff on security best practices, or implementing new security measures. Following up with a retest can confirm that the issues have been effectively resolved. Remember, the goal of pentesting isn’t to pass a test—it’s to improve your security posture.
Setting Up a Pentesting Schedule: Timing is Everything
The frequency of pentesting can vary depending on several factors, including the size and nature of your startup, the sensitivity of the data you handle, and your regulatory environment. However, a good rule of thumb is to conduct a pentest at least once a year. More frequent testing may be necessary if you make significant changes to your systems or if you handle particularly sensitive data. Regular pentesting ensures that you stay on top of new vulnerabilities that may emerge over time.
Choosing a Pentesting Provider: Key Considerations
When choosing a pentesting provider, consider their expertise, reputation, and the scope of services they offer. They should have a strong track record of working with businesses of your size and in your industry. They should also provide a comprehensive service that includes both the testing phase and a post-test analysis with actionable recommendations. Also, consider their communication skills—your provider should be able to explain their findings in clear, understandable language.
