A penetration test (Pen Test) is one of the best ways a company can test their IT assets for vulnerabilities that a hacker could exploit to access sensitive data (customer, internal IP, passwords, etc.). Many internal IT teams assume that a pen test is a time-consuming nightmare, but, with the right communication and preparation, a pen-test is an effortless, vital, and valuable procedure for any business.
Penetration tests are simulated cyberattacks against an IT system by security professionals to find exploitable vulnerabilities a hacker would use to infiltrate an organization. Finding these vulnerabilities allows you to address the gaps in your network defense and enhance your overall security posture. Additionally, it provides you with an opportunity to assess your active protection systems, incident response, and on-going security monitoring.
Why does a company need a penetration test?
- To detect and remediate vulnerabilities before an adversary exploits them
- Upper management may want a better understanding of their current security posture
- It may be a regulatory requirement of the industry, or a legal requirement to do business with another company
- Data protection increases customer confidence
Who will be involved in the Pen test?
- Management and authorized technical leaders of the company.
- The internal IT teams.
- The external penetration testing company.
Ask these questions before you start the Pen Test
Our experience testing over 1000+ application and 500+ networks. Based on their experience, they recommend asking and discussing the questions below. The details should be agreed upon by your team and the penetration testing team before commencing the tests.
- Will the test include DoS, DDoS or Brute forcing?
- How will the security team perform the intrusive test?
- Will the test team exploit vulnerabilities they find or just identify them?
- How long will it take to perform the pen test?
- What will be included in the report? If possible, ask for drafts or interim reports for longer engagements.
- Will there be regular meetings to discuss test progress and concerns?
- Will they provide an escalation matrix for both teams?
- When will they notify all stakeholders regarding the test and get necessary approvals?
- Will there be legal documentation between stakeholders and test team?
How should you prepare for the Pen Test?
If you plan to run a penetration test on your IT system, it’s important that you, your IT team, and staff prepare for it. It’s possible to prepare for a pen test in a few hours, but it helps if you know what to do. Here are 6 ways your company can prepare for a Pen test –
- Identify and communicate your scope and objectives with the security professionals conducting your pen test
Prepare an inventory of your technology assets and assign values to each based on business impact. This will help you to identify and prioritize the assets that should be tested. It would be ideal to discuss the scope with the penetration testing company and/or compliance teams.Spend time with the IT team and security testing company and create a concise and realistic project description with objectives and expectations. For example, do you want to test your company’s ability to detect intrusion attempts? Or see how well your IT team responds to a possible breach? Make these goals clear to the IT Team and penetration testing company.
- Decide on the best time to conduct the test
Pen testing is a time-sensitive process and can take longer thank expected if issues arise. It’s best to run this test during a time of low business activity. Depending on the business, weekends might be ideal to perform this exercise.
- Backup your data
Your IT team should make a backup of all configurations, data, and codes before the test begins. It’s possible that the pen test may cause a system to crash or data to be lost. If this happens, the data can be restored to pre-test configurations. Your internal IT or support team should be readily available to resolve technical issues with the testing company during the testing phase.
- Ensure that your internal IT team is available
Your internal IT team or support team should be readily available to resolve technical issues with the asset during the testing phase.
- Explain what you want to see in the report
- Do you want to see an Executive summary that describes the work done in a way that management can understand and act on?
- Do you require mapping of the findings to a regulatory, or compliance standard like PCIDSS, HIPAA, HITRUST, etc.?
- Do you want to see a detailed record of the findings of the test?
- Would you like any specific metrics to be included in the final risk rating of the findings?
- Mitigating common vulnerabilities
Security is an ongoing process, so it is helpful to mitigate common vulnerabilities before you go ahead with the test to ensure optimal results. More than 67% of detected vulnerabilities are common and can be mitigated through basic security measures.
- Applying missing patches
- Restrict access to management or administrative interfaces
- Disable insecure encryption standards and ciphers
- Decommission obsolete software, services, and systems
- Ensure password strength is maintained across all assets (network and application)
- Validate all inputs on the server side
What is included in the Pen Test report?
A detailed report that includes:
- The goals and scope of the penetration test
- The methodology used by the security company
- The timeline of the penetration test.
- Detailed list of vulnerabilities, risk ratings, and evidence
- Recommendations to improve overall security
Penetration testing is not a one-time activity. In 2018, there were 16,412 common vulnerabilities and exploits released, which is why penetration testing and vulnerability assessments need to be an ongoing process as most attackers leverage known exploits and vulnerabilities to attack organizations. It is important to ensure that penetration testing is a part of the development cycle and at a minimum be carried out before every major release if not biannually.
