Penetration Testing

We are the providers of external and internal network penetration services, which could help reveal vulnerabilities before “real” hackers do. All this in a controlled and secure framework and without exploiting the security gaps found, so you could see the holes in your cybersecurity and fill them with the modern cybersecurity tools – no one unwanted could ever get in.

What is a penetration test?

A week rarely goes by without reports of attacks on sensitive systems. It results in financial damage, and the reputation and trust of customers and partners crumble. 
To protect yourself against attacks, adequate countermeasures must be taken at different levels. Well-trained employees and processes that also take IT security into account are essential for effective protection. However, above all, the security check through a penetration test by an independent third party is an effective means. 
So, what is exactly a penetration test? A penetration test is an authorized, planned, and a simulated cyber attack on a company or a public sector institution. The aim is to identify and eliminate previously unknown points of attack before hackers can use them to steal intellectual property or other sensitive data or otherwise damage an organization.
During the penetration test, trained testers attempt to attack your IT systems using the methods of criminal hackers to determine the vulnerability of systems, after which appropriate protective measures can be taken.


Types and models of penetration testing

There are several types of penetration testing, and the method applied largely depends on the goals of the client and the desired gain in knowledge after the test. The penetration test that is currently most frequently used is an attack via the network. 

    The attack via the network
    Social engineering
    Wireless networks test

    Web application tests
    Cloud penetration testing
    Physical penetration testing

External network penetration testing

Anything exposed to the Internet needs some form of security testing. If an external host is compromised, it can lead to an attacker digging deeper into your internal environment. External network penetration testing is focused on the perimeter of your network and identifies any deficiencies that exist in the controls that protect against remote attackers targeting the Internet-facing systems in your environment. When performing external penetration testing, our penetration testers mimic real scenarios as best as possible to root out all potential vulnerabilities.

Our external network penetration testing techniques include the following:

● Port scans and other network service interaction and queries● Network sniffing, traffic monitoring, traffic analysis, and host discovery● Spoofing or deceiving servers via dynamic routing updates (e.g., OSPF, RIP spoofing)● Attempted logins or other use of systems with any account name/password● Use of exploit code for leveraging discovered vulnerabilities● Password cracking via capture and scanning of authentication databases● Buffer overruns/underruns● Spoofing or deceiving servers regarding network traffic● Alteration of running system configuration except where denial of service would result● Adding user accounts.

This service is designed to identify and exploit issues that can be discovered by an attacker who has gained access to your internal network:

 Internal subnets Domain servers File servers Printers Network devices Phones Buffer overruns/underruns Workstations and laptops

Internal network penetration testing

Whether it’s disgruntled workers, previously terminated employees, or someone trying to steal trade secrets, there is a high chance of potential internal threats. Even without malicious intent, simple configuration issues or employee mishaps can also result in a network compromise, leading to the majority of attacks originating from within. Our internal network penetration tests target the networked environment that lies behind your public-facing devices.

Web applications penetration testing

Web applications are unique constructs, mixing various forms of technology and providing an interactive front for others to use. Some web applications are made public, while others might be internal applications existing on an intranet. No matter the location, there are always security variables. How well does your application handle input? Does it work with backend servers in a secure manner? Will your session management scheme hold up to penetration testing?

Web application penetration testing tests for the following:

● Application logic flaws● Forced browsing● Access and authentication controls● Session management● Cookie manipulation● Horizontal escalation● Vertical escalation● Brute-force password guessing● Poor server configuration● Information leakage● Source code disclosure● Response splitting● File upload/download attacks● Parameter tampering● URL manipulation● Injection attacks for HTML, SQL, XML, SOAP, XPATH, LDAP, Command● Cross-site scripting● Fuzzing

Why do you need a penetration test? 

There are two types of businesses:

    those that have been already hacked
    those that will be hacked once

To effectively protect yourself against hacker attacks, penetration tests can give a clear picture of the system’s security situation. We give eight reasons why organizations need regular pentests.

Protection of data and intellectual property

A penetration test reveals weak points and checks how vulnerable a system is. Together with the customer, security measures are then taken to protect data in the event of an actual attack by malicious hackers.

Protection against Loss of reputation

A penetration test, conducted by an independent third party, reduces the risk of an attack and thus protects against a possible loss of reputation.

Fulfilling legal obligations

Sensitive data require special protection. In the context of IT governance, numerous legal requirements require the proper operation of an information security management system.

Understanding the current threat situation

It is best to find and fix vulnerabilities before criminals find them.

Recommendations for safeguarding measures

Anyone who has a penetration test carried out receives a detailed report that enables your IT management team to understand the risks of the current situation and gives IT specialists recommendations for specific security measures.

Quality management

Many companies set up internal QM systems to ensure the quality of services and products. In addition to code reviews for software products, penetration testing can be used to check and measure the reliability of information technology. 

Certifications and Compliance

For certain industries and processes, it is necessary to meet standards. For example, companies that conduct credit card transactions must comply with the PCI data security standard. To achieve compliance, it is necessary to check systems by an independent third party. A security level proven by a penetration test is a clear competitive advantage here.

Cheaper premiums for cyber risk insurance

Anyone who has implemented sufficient control and protection measures for their systems reduce the risk of a successful attack by hackers. Cyber-risk insurance providers see it that way and calculate their insurance premiums accordingly. Some insurers even only offer their products if there is a minimum level of IT security.


Who needs a penetration test?

If you are not sure how secure your IT environment is, and you would like to know where are the back doors are in your system, you want to prove that data security is important to you, and you would like to prove that the company is managed properly, conscientiously and professionally by the management in the area of IT security, then the penetration testing is the right option for you.

Process and analysis

A penetration test is usually roughly divided into five phases:

Phases 2 - 4 are usually repeated several times.The actual penetration test usually begins with a tool-based scan of the network.

  • Stage 1. Preparation

    Coordination of test objectives, scope, test methods, and devices.

  • Stage 2. Scanning phase

    At this stage, we are looking for open paths to the computers. The system is "touched" for the first time. Here we are attempting to obtain information from different sources.

  • Stage 3. Enumeration

    This phase often runs at the same time as stage 2. Its goal is to get real, useful information through the security check. To carry out the attacks successfully, it is necessary to obtain the most accurate information possible about the system. At this stage, we search for suitable exploits, conduct detailed network analysis, hash cracking, and coordinate further attacks.

  • Stage 4. Exploit phase

    The vulnerabilities found must now be exploited to carry out real attacks on the system. In this way, existing security gaps and weak points are revealed. Here we conduct the verification tests (exploitation of vulnerabilities, circumvention of security measures and active intrusion, man-in-the-middle attacks, post-exploitation, etc.)
    Then we repeat levels 2 to 4.

  • Stage 5. Evaluation and reporting

    To be able to realistically assess the actual security situation, a detailed and comprehensive report is necessary. Management can derive appropriate measures from the management reports to achieve proper IT security. During the final analysis, we evaluate and document the results, make the summary and presentation, and listing of weak points, and give recommendations for countermeasures.
