6/3/2023 0 Comments Best network scannerNetwork scanners are, for example, Offensity, OpenVAS (open source), Nessus from Tenable or Nexpose from Rapid7.Ī network scanner is usually the best basis for vulnerability scans and can be recommended as a first step. They usually check web applications only superficially and without authentication. These scanners often have their greatest weaknesses in checking web applications (this is also the reason why web scanners have become established as a specialized form of vulnerability scanner). They provide a more comprehensive picture of the vulnerabilities in an IT environment. Network scanners check (at least in theory) all services accessible via the network. These include, for example, the web application scanners from Qualys or Acunetix. What good is it for a company to have a super-secure website if the data can be read and modified via a file server (like FTP) without logging in? Web scanners are specialized vulnerability scanners that are most likely to pay off for software vendors and companies with a particularly large number of web applications. Pure web scanners only check web applications for security vulnerabilities. Often, the attack path also begins at externally accessible systems, allowing the attacker to jump into the internal network. An attacker must be highly aggressive and include serious criminal intent to carry out such an attack. Internal networks are often accessed by attackers via malware that employees download from the Internet or receive by e-mail. They are often the primary target of attack because they are constantly available and can be discovered "by accident" in mass attacks. Systems that are accessible from the Internet can be attacked by attackers from around the world 24 hours a day, seven days a week. Which criteria should you use to decide? And which one is best suited to your use case? This guide tries to help in making a good decision. The choice of vulnerability scanners is vast.
