Penetration testing involves frequent internal security audits conducted by a team of trained employees or IT professionals. The experts who perform penetration testing are called “pentesters.” Pentesters have the technology and hacking skills to fake a hack of your system, network or application. The information gathered during the planning phase helps network experts conduct the actual penetration testing. The testing process is based on variation and identifies different aspects in the software applications and environment that are being varied.
This helps ensure that software applications work under both reasonable and unreasonable circumstances. When penetration testing is done correctly, network experts can use the results to make recommendations on how to fix the problems discovered during the penetration test in the network. The main goal of penetration testing is to improve network security and protect the entire network and connected devices from future attacks. Cybersecurity professionals use penetration testing to improve an organization’s security posture and eliminate vulnerabilities that leave it vulnerable to attack. External scenarios simulate that the external attacker has little or no specific knowledge about the target and operates solely on assumptions.
Penetration testing can be very valuable, but it requires a lot of work and expertise to minimize the risk to the affected systems. Penetration testing can damage or disable systems, although it is beneficial for the organization to know how an intruder might disable a system. Although experienced penetration testers can mitigate this risk, it can never be completely eliminated. Penetration testing should only be conducted after careful consideration, notification and planning. As websites and web applications increase in number, their weak security measures make them easy targets for hackers attacking larger networks.
As networks, applications, and information needs become more complicated and critical to business and government operations, these systems become more targeted and vulnerable. Pen testers are at the forefront of technical expertise and operate closer to the role of potential attackers. The best pen testers are highly regarded by information security stakeholders today, and there is no indication that this view will change in any way. Penetration testers are hired by network system operators and web-based application vendors to look for vulnerabilities that hackers can maliciously exploit to obtain secure data and information. In external network penetration testing, pentesters hack into your systems without first gaining access to your network. In other words, pentesters using this testing method access vulnerabilities in your network from the periphery of your systems.
Care must be taken when conducting physical security checks: Security personnel must know how to verify the validity of the auditor’s actions, such as through a point of contact or documentation. Another non-technical attack method is the use of social engineering, such network security as posing as a help desk employee and calling to request a user’s passwords, or posing as a user and asking for a password reset. It should be part of a continuous monitoring system to ensure the security of organizations through various types of security testing.
Therefore, ethical hackers and ethical hacking play an important role in today’s cybersecurity landscape. Candidates gain penetration tester skills by working in entry-level IT positions, including security and systems or network administration roles. After 1 to 4 years on the job, aspiring professionals typically have the knowledge and experience needed to obtain a penetration tester position. Davis’ book, “The Art of Network Penetration Testing,” addresses the skills he learned during his career as a “professional hacker,” Davis said. Through ongoing cyber monitoring and regular cybersecurity training for employees, internal network penetration testing can help your organization prepare for this very real possibility. The goal of network penetration testing is to identify vulnerabilities that put your organization at risk of a data breach before hackers can discover and exploit them.
Web sites that provide domain name registration information (e.g., WHOIS) can be used to identify the owners of address spaces. Because the tester’s traffic typically passes through a firewall, the amount of information obtained from the scan is much less than if the test were performed from an internal perspective. After the testers identify the hosts on the network that can be accessed from the outside, they attempt to compromise one of those hosts. If successful, this access can be used to compromise other hosts that are not normally accessible from outside the network.
Penetration testing allows organizations to assess the overall security of their IT infrastructure. An organization may have solid security protocols in one area while being deficient in another. The high cost of a successful cyberattack means that no company should wait for a realistic scenario before going on the offensive. Using penetration testing to uncover vulnerabilities in an organization allows security professionals and pen testers to address vulnerabilities before they become a critical liability.
Network security professionals are well-trained in other security controls used on your company’s network. Controls include encryption procedures, firewalls, data loss prevention, layered security procedures, and more. A network security specialist has the knowledge and experience to perform appropriate penetration testing to ensure that network security controls are working. Penetration testing is performed by ethical hackers who have been given permission to perform simulated attacks on an organization’s web applications or network security. Legal permission is required because penetration testing is often performed by third parties that provide penetration testing services. The security team builds on the foundation established in the previous phases and begins penetration testing.
