The purpose of network penetration testing is to identify potential threats in internet connections, corporate networks, VPNs, local networks, wireless access, and cloud systems. Read more in our Shieldcast expert series.
Role of Network Penetration Testing in Improving Security
Every service-based organization now places a high priority on cybersecurity, as any security loophole can be used as an easy target for malicious attacks. Therefore, concentrating on thorough security testing procedures is the best strategy to secure sensitive data. The major reason network penetration tests are important for an organization's security is that they teach staff how to deal with any form of malicious entity break-in. To find risk factors connected to crucial cybersecurity implementation projects, network penetration testing is necessary. Even though doing penetration tests on a regular basis is important, many people outside of the cybersecurity industry are unaware of its importance.
What Is Network Penetration Testing?
Network penetration testing is an attempt to breach an organization’s network, with the objective of identifying security weaknesses in the network. Modern networks are extremely complex, with a combination of WAN/LAN, servers, workstations, IoT devices, and security technologies like firewalls. The weak link among these will allow attackers to penetrate the network.
Types of Network Penetration Testing
Each kind of penetration test has a different set of skills, procedures, and resources that must be used, and it should be in line with a particular business objective. The types of network penetration testing services that must be performed while evaluating software products are:
Internal Network Penetration Testing: Internal network penetration testing is performed to detect what an attacker could achieve with initial access to a network. It can mirror insider threats, such as employees intentionally or unintentionally performing malicious actions.
External Network Penetration Testing: An external network penetration testing is designed to test the effectiveness of perimeter security controls to prevent and detect attacks, identifying weaknesses in internet-facing assets like web, mail, and FTP servers.
Based on a survey, the most common cyber attacks experienced by US companies are of the following kinds:
Stolen/lost device or records
As per the study, it comes as no surprise that people and organizations are worried about potential hacking situations and information breaches. Other than revenue losses, such varieties of cyber attacks will result in a bad reputation and will subject businesses to strict government rules and expensive settlements.
A network vulnerability is a flaw or weakness in organizational procedures, hardware, or software that, if exploited by a threat, could lead to a security breach. The image below shows some network vulnerabilities:
Types of "Network Security Threats"
If your business is aware of the threat described below, you can develop more thorough policies and procedures to protect your organization’s data security.
Importance of Network Penetration Testing
Be it startups, mid-market, or enterprises, it is critical for organizations of any size to do penetration testing on their systems and infrastructure to make sure that there are no security breaches that might cause harm to reputation or revenue loss. Listed below are some of the most important factors why penetration testing matters:
Penetration tests should be done in order to learn if the security controls you have in place actually work. Pentest gives you real-time experience in dealing with an attack.
Network security penetration testing helps in detecting what vulnerabilities lie in your network. Without prioritization, we can not check which of these vulnerabilities to patch first.
Pentest is done to uncover loopholes in your network. Penetration testing does whatever possible to breach your network in a similar manner as a hacker.
Determine Attack Vector Feasibility
Penetration testing vendors enable security staff to effectively identify and respond to various forms of cyber attacks
Network Security Testing Tools
The best network security testing tools give you a complete picture of your network's security state. Below are the most popular tools to test for session security.
Wireshark is an open-source tool that is used to capture and interpret network packets. The tool is available for various systems, including Windows, Solaris, FreeBSD, and Linux.
Aircrack is an open-source tool that is used for cracking flaws within wireless connections by analyzing data packets for an effective protocol for exporting text files for analysis.
Best Practices for Network Security
As a variety of useful network penetration testing tools are available, system scanning services can be completed quickly and with older, more convenient services. Let us take a look at how you can secure your network from a security breach:
Regular Patching of the System
Organizations must keep software up to date with the most recent security patches. By managing patches, you can make sure that all latest software updates are implemented so that any known vulnerabilities have been fixed.
Use of Strong Encryption Protocol
Security isn't always equated with compliance, but it can offer valuable advice on how to mitigate risks. Organizations can prioritize vulnerability fixes and save downtime by conducting periodic risk assessments.
Effective Firewall Rule
A network firewall should be as effective as possible. In addition to defending your network from external security threats, network firewall settings must also guard against malware that could leak critical data to other networks.
Do Not Use Outdated Software
Installing software or apps is only advised if they come from reliable, well-known sources. Before allowing applications access, confirm what data they will have access to. Keep it updated after installation.
A network vulnerability is a weakness or flaw in the software, hardware, or organizational processes, which when compromised by a threat, can result in a security breach.
