A network infrastructure ready for cyber attacks is ideal for every organization. You should conduct penetration tests on your network regularly to identify and fix vulnerabilities against new cyberattack tactics. It is much less costly than the damage that will occur due to being exposed to risks. Security for Everyone has experience in network security testing services and always keeps your organization safe from up-to-date attacks, using the most up-to-date technology.
Our experts first understand your expectations and define the scope of the network security testing services. You get a service tailored to your organization and business goals.
Network security testing services experts use the latest technology to discover your network infrastructure's details. A useful discovery enables the right action plan for a penetration test.
After a successful weaknesses discovery, our experts start their penetration tests to determine your network infrastructure's vulnerabilities.
Our experts produce a report including key findings and suggestions to fix these weaknesses and improve network security.
You can find the list of the vulnerabilities we encountered the most while pentesting a network by connecting to an internal or online network.
It would be beneficial to look at the list even though the vulnerabilities are not limited to listed below.
Not installing security patches of the services accessible over the internet is one of the most common vulnerabilities we encounter with. Among the known vulnerabilities, this is the one for network infrastructure, especially those whose exploit codes have been published. It is one of the most dangerous ones.
Most time, both client-side and network-level firewalls are not configured with the best practices. Firewalls still do many things to prevent an attacker from gaining access and making lateral movement at the network layer.
We do not know why, but during our network security testing services, we generally find an outdated OS in the IT infrastructure (for OS infrastructure, this may be understandable).
Almost all network services use passwords for authentications. Therefore, a hacker with network access can use a brute force or dictionary to access the network services.
Vlans are used to separate devices and manage access control at a network level. Even a tiny misconfiguration in the network devices can make hackers access other VLANs..
If necessary hardening is not done on the server, processor, and network devices, hackers would not only break into the systems but also can perform malicious transactions as well as progress horizontally or authorization escalation.
Failure to do sufficient logging and monitoring cause the inability to catch how and by whom the event occurred. Additionally, insufficient logging makes it hard to detect a cyberattack, impossible even for most of the time. Therefore, in the network security testing services performed by S4E Team, suggestions are made to fully collect the necessary track records by working with the customer.
