Why one should conduct Penetration Testing: Everything You Need to Know

What is a penetration test, and what are its objectives?

A computer security assessment is a unique attack to assess its security. A penetration test aims to identify vulnerabilities that an attacker could exploit and gain access to sensitive data or systems. Pen tests can also assess the effectiveness of security controls, such as firewalls and intrusion detection/prevention systems.

Penetration tests can be conducted using manual or automated methods. Manual testing generally requires more time and resources. Still, it can be more thorough because it allows testers to use their knowledge and expertise to find vulnerabilities that may not be detectable by automated tools. Automated testing is typically less expensive and faster, but it may miss some types of vulnerabilities.

Most penetration tests follow a similar process, which includes surveillance, scanning, exploitation, and post-exploitation. Surveillance is the first stage of an attack and involves gathering information about the target system, such as IP addresses, domain names, and open ports.

Information on the system’s vulnerabilities and configuration can be found manually or by automated tools. The intruder will check for open ports and services after gathering the information. Then, look for any flaws that may have been discovered. Finally, post-exploitation activities are carried out to maintain access to the system and gather sensitive data.

Penetration tests can be conducted internally or externally. Internal tests are conducted by employees of the organization who have authorized access to the tested systems. Third-party security firms conduct external tests without authorized access to the tested systems.

Penetration tests can test the security of any type of system, including web applications, networks, and even physical facilities. Therefore, when choosing a penetration testing company, you must ensure they have experience with the type of system you are testing.

It is also important to note that qualified and experienced individuals should only conduct penetration tests. Attempting to conduct a penetration test without proper knowledge and tools can damage the tested systems.

The first step in conducting a penetration test is reconnaissance. This involves gathering information about the target system, such as IP addresses, domain names, and open ports. This information can be obtained manually or by using automated tools.

Once the information has been gathered, the attacker will scan the system for vulnerable ports and services. Then, exploit any vulnerabilities that are found. Finally, post-exploitation activities are performed to maintain access to the system and collect sensitive data.
