Top Pen Testing Tools In 2023 To Secure Systems From Brute Force Attacks

The cost of IT downtime can vary significantly by industry and organization size. What does one minute of downtime look like to your organization? One recent study conducted by IDC on the Fortune 1000 found that the average hourly cost of an infrastructure failure is $100,000 per hour. That’s an expensive affair for 60 minutes, which is why many organizations employ pen testing to secure their infrastructure and information from brute force attacks. API keys and SSH logins are also frequent targets of brute force attacks. The login page of a website is frequently targeted by scripts or bots that employ brute force password attacks.

What distinguishes brute force assaults from other cracking techniques is that brute force attacks do not involve an intellectual plan; they just test various character combinations until the correct one is discovered. This is comparable to a criminal attempting to break into a combination safe by trying every possible number combination until the safe unlocks.

IMPORTANCE OF PEN TESTING

The purpose of a pen test is to strengthen an organization’s defenses against potential threats to better detect, prevent, and respond to security incidents.

Pen testing helps firms evaluate their security by simulating assaults similar to those that hostile hackers would carry out, therefore revealing any vulnerabilities that may go undetected.

To accomplish this, brute-force attackers employ a wide variety of methods. For Penetration, you can use the brute-force attacking tools themselves. “pen testing” is also used to describe this analysis. 

The penetration test involves simulating an actual cyberattack on one’s information technology infrastructure. Through this, you can spot potential vulnerabilities.

STEPS OF PEN TESTING

  1. Preparation and Investigation

The scope of the test, the approach is taken, and any necessary background information for the tester are all things that should be worked out in advance. At this point, both the tester and the target should have a solid grasp of what to expect from one another and what data the tester might have access to.

  1. Searching

Scanning is the action of searching for security flaws. Scanning might be static or dynamic. To determine how an app or other target behaves and is tested, static scanning analyzes its source code at a fixed point. It scans the code or other targets while running and provides a real-time look at any issues that may arise. Dynamic scanning is more complex but provides a more helpful test benchmark because it is not a static image.

  1. Gaining Entrance

When the scanning process is complete, the tester will attempt to breach the system’s or app’s security by using the vulnerabilities discovered during the scan. Depending on the results of the scanning procedure, several tools and approaches may be employed.

  1. Maintaining Access

It’s one thing to break into a system and steal data or cause damage, but it’s another thing to keep that access going for long enough to do any of those things. At this point in the testing process, we’ll know if the flaws allow an attacker to gather information or plant a more serious security risk on the system. A hacker may only need temporary access to a system to plant a backdoor that grants them permanent, extensive access.

  1. Investigation 

After the test has been completed, the data is analyzed to learn more about the system’s vulnerabilities, the information gained by the tester, and the length of time the connection was maintained. Your security team will be able to patch the holes and prevent “real” attackers from taking advantage of them once they have this information.

What to Look for (and Avoid) When Deciding on a Pen Testing Vendor or Service Provider

1. Make sure the team is experienced and properly trained

This is a significant factor to take into account. Finding a pen test firm that employs skilled pen testers is a must when shopping around for a service. Employees, for instance, would have one of the following professional certifications: CEH, GPEN, GWAPT, OSCP, OSCE, or SANS GXPN. It’s also helpful to find out what kinds of prior work experience are preferred throughout the recruiting process, as well as whether or not the organization provides possibilities for continuous training and growth.

2. Prioritize Risk Avoidance

Inquiring about the company’s systems for vetting new hires’ honesty and integrity is just as crucial as asking about their education and work history. Do prospective employees’ pasts being checked before employment? Does the organization have a system in place for regular security audits? Some form of screening and verification is necessary for pen testers since they can access sensitive information about the company’s internal infrastructure.

  1. Go with a firm that doesn’t hide anything about the way they do business

When choosing a vendor to outsource penetration testing to, businesses should make sure they use a tried-and-true penetration testing technique. The team must detail what will be tested, for how long, using what tools and methodologies, how sensitive information will be handled, how data will be accessed, and what kind of reports will be sent. Be sure that the company’s capabilities in terms of the services it can offer are commensurate with the requirements of the business.

Make sure the vendor is trustworthy in their service offerings and can confirm their findings through written documentation or verbal communication that highlights the step-by-step methodology used, which can offer reproducible results and can provide realistic solutions if you’re expecting something like an assessment of the organization’s security posture along with clear recommendations.

  1. Verify if the organization uses cutting-edge practices

Companies can offer a wide range of penetration testing services, using a wide range of pen test tools for different platforms and frameworks that can be modified to suit specific situations.

They should start with the homework. Always hire a company verified as up-to-date in their field with appropriate certificates, credentials, and standards compliance. Verify that while doing security audits, they also employ the most cutting-edge commercial penetration testing tools and methods.

  1. Make sure a well-thought-out contract is drawn out

You should provide the vendor with a specific window to test your network or application and specify which systems will be “off limits” during that time.

If you’re looking for an on-demand penetration testing service, you must specify the turnaround time for each test. Get the vendor and client to sign a “Rules of Engagement” (ROE) document outlining the parameters of the test and the expectations each party has for the results.

  1. Securing Information 

Even after receiving guarantees during contract negotiation, it is prudent to ask pointed questions concerning the transmission, storage, and disposal of data before transferring it to a third party. For what length of time are files kept? Asking whether there have been any hacking attempts against the firm.

  1. Verify that the business carries liability coverage

An insured company provides the added safety net. Suppliers must have liability insurance if something goes wrong during testing or an attempted infiltration causes financial damage. Verify that the vendor doing the pen test has insurance that adequately covers any losses due to a leak or breach of sensitive information.

  1. Verify the credibility of the provider

Pen testing, like any other service, is best sought by established businesses with a solid reputation. In the same way, you would before making any further significant investment, ensure you conduct your due diligence by checking references, reading consumer reviews, and speaking with previous customers if possible.

There is always some degree of danger anytime a third party is granted access to a company’s systems or information, no matter how restricted that access is. Does the vendor have a solid reputation in penetration testing and vulnerability research? Nothing being discussed online in the InfoSec community is a warning sign in and of itself.

  1. Focusing on a Niche

There’s no reason to automatically rule out a pen testing firm just because they claim to have worked in every imaginable setting and testing situation. With so many options, it’s difficult for any expert to be well-versed and experienced in them all, no matter how well-established the company’s infrastructure may be.

Therefore, it is essential to have an early conversation about the systems, software, and setup that the pen testing tools will be expected to work with and to assess the actual level of competence that the pen testing organization can exhibit with similar installations.

  1. Watch out for the super-technical language

While penetration testers need to be thorough in their approach, it’s not ideal if management is flooded with technical jargon when discussing the pen testing processes or when getting incomprehensible findings for the layman.

One of the most desirable qualities in a pen tester is the ability to explain complex ideas so executives with little technical knowledge can understand and act upon them. Look at sample reports, ask questions, and evaluate how nebulous the answers are. Look for clarity and shy away from smoke thrown in your eyes.
