Network Vulnerability

Network vulnerabilities constantly evolve, resulting in the loss of valuable information and revenue from businesses. Though threat actors can find new weaknesses every day, some of their methods remain the same. Hackers have tried-and-true methods for infiltrating a seemingly secure network, and they employ various tricks, devices, and information to get the job done.

Small businesses often do not give their network systems adequate protections, either because their leaders do not incorporate strong security policies or do not fully understand how to guard their systems. Exploitable bugs and weaknesses are always present within networks, but understanding how hackers manipulate them gives businesses a clearer picture of what they must do to prevent authorized users from accessing any valuable digital asset.

Without adequate web security measures, the network becomes susceptible to devastating cyber attacks like distributed denial of service attacks that bring down database servers or restrict authorized user access to block out workers and IT management teams.

Every device within the network can be problematic for a business unless the IT department is aware of them and maintains each one with the most recent firmware upgrades available to patch flaws. Routers are an example of hardware equipment. If the IT department chooses not to use firmware to upgrade the device or if no patches are available to fix a known weakness, they must replace it with the latest model with up-to-date patches.

The easiest way for an intruder to infiltrate a network is by using a device containing a virus or malware directly on a machine already connected to the system. They can install the malware quickly into the equipment using USB drives or download codes. The malicious application will either install spyware or a backdoor code that could capture vital information that would provide access to more sensitive data, like keystrokes or the option to view network traffic.

Firewalls are a must-have measure for all businesses with web networks, whether they are part of a router, separate box, or virtual device. The firewall prevents unauthorized access and blocks blacklisted IP addresses from open ports. Sometimes firewalls upload unnecessary or unwanted services into the network as part of its program.

Another benefit of using firewalls is its ability to block cross-site scripting and SQL injection attempts. SQL injection is a hacking technique that interferes with application queries to view sensitive data. Having multiple firewalls is necessary for segmenting a network containing confidential information beyond the edge of the network, which is more accessible to anyone attempting to hack the system from the outside.

Wi-Fi is a convenience that many businesses use, but it poses a severe vulnerability because it immediately gives users access beyond the firewalls. If it is not password protected, it is accessible to anyone, including intruders looking for ways into networks. With wireless access points, network security is at risk because all devices with an internet connection can read traffic flowing in and out of the network.

As of 2020, there are an estimated 20.4 billion devices connected to the IoT, the "internet of things." The term refers to a collection of objects like thermostats, light bulbs, and locks that can compute and analyze data. They have sensors or software that allow them to connect to a system, network, or device and transmit data over the internet.

Laptops and smartphones also pose threats to the operating system. They are discreet, they have their own complete operating system, and they have Wi-Fi network connections. A laptop or netbook can also use its ethernet port to connect directly to the system.

Outdated software continues to be the root of network vulnerability and subjects your business to a greater chance of a network attack. To circumvent this problem, the security team must install software updates as soon as they are available. The business should also perform a vulnerability scan and conduct penetration testing to ensure network security is up to date.

Employees do not have to be disgruntled to become a network vulnerability. They can risk network security by accidentally accessing a file system without approval, reading confidential information on their monitor without being aware of who is watching, and not verifying intruders in disguise.

Finding network vulnerabilities requires the right vulnerability scanning tools. These tools include the ability to locate and identify network devices, open ports, and software within that network. The vulnerability scanner collects this data from the system and identifies these items. Then, the scanner is able to assess this data and compare vulnerabilities to the known database.

A scanner should also know when new connections and new devices are added to the network. New vulnerabilities can show up with new hardware, new programs, and new devices added to the network. The right scanner should automatically scan whenever something new is connected.

In order to understand network vulnerabilities, it is important to first understand what networks are and how they operate. Networks can be broadly defined as systems of interconnected computers and devices that can share data and resources. The most common type of network is the Internet, which is a global network of computers and devices that allows for the exchange of information between users.

Network vulnerabilities can occur for a variety of reasons. One common reason is when there are flaws in the design of the network itself. Another reason is when there are flaws in the way that the network is configured or implemented. Finally, vulnerabilities can also occur due to weaknesses in the security controls that are in place to protect the network.

Penetration testing, also known as pen testing or white-hat hacking, is the process of simulating a cyber attack on a computer system to check for vulnerabilities that could be exploited by malicious actors. Pen tests can be used to test the security of an entire network or individual systems, applications, or devices.

Your firewall monitors incoming and outgoing network traffic and allows you to set up rules for access that prevents unauthorized sources from entering your network, or from people on your network from accessing security threats. This is an essential part of your security, but it has to be used correctly in order to block threats.

Spam emails are a common vulnerability for a business and an incredibly effective way for a hacker to deliver malware as they are able to mimic and copy reliable sources. As soon as an employee opens the email, they are opening up your network to attack. Instead of risking your organization with every email, installing effective email and spam protection will ensure you and your team are only opening communication from trusted sources.

In this article, I will go over the definition of a network vulnerability, as well as the most common types that businesses have to deal with. So, if you want to find out what they are and what makes them particularly dangerous for your enterprise, keep reading.

An internal network vulnerability is usually caused by misconfigurations, bugs, poorly written code, or even employees. External network vulnerabilities are represented by the devices or platforms a company uses daily.

A common issue with mobile devices relates to physical theft. When an employee connects their phone or tablet to the corporate network and uses them to access sensitive data, this opens up a world of possibilities for cyberattackers. Thus, stealing such devices is an opportunity some malicious actors will take. Some might even resort to using a more intricate strategy based on lookalike apps that trick the user into disclosing private information.

The Internet of Things consists of interrelated computing devices with the ability to transfer data within a network, but are outside the spectrum of what we generally consider as part of the system. An on-premise office makes no exception, as many companies have IoT devices such as smart thermostats, surveillance cameras, or even refrigerators.

The situation becomes even more complicated when the enterprise operates remotely. Your employees can have a variety of IoT devices in their homes, and they can be as small as a smartwatch or as large as an oven. Their commonplace nature is why they are often overlooked as potential network vulnerabilities, but the truth is that IoT security is essential to the digital safety of an enterprise.

After the border router, the firewall is the next line of defense your data has against malicious third parties looking to exploit a network vulnerability. A powerful network security system that blocks unauthorized access to a computer or network, it is used by many organizations and individuals as part of their overall security strategy to protect their data and devices against Internet-based attacks.

This is why a misconfigured firewall can prove fatal for the digital integrity of an organization. This type of situation is usually caused by an error of the network administrator, such as in the case of the 2019 Capital One breach. However, the root of the problem can also be improper firewall patching or management.

A secure Wi-Fi connection can be achieved by using WPA2 encryption, changing the default password and using a strong password, changing the name of the network from its default, and disabling unknown devices from accessing your network. 041b061a72
