6 Common Network Security Problems and How to Fix Them

Today’s modern technology and the increasing use of hosted solutions have brought major changes to application and network infrastructures.

While such changes have empowered businesses with more functionality, some suffer countless network security issues without realizing it. Worse, when such issues go unaddressed, they can create pathways for attackers to breach your organization’s security infrastructure to wreak havoc and steal your data.

Fortunately, by working with managed service providers CloudSecureTech in Boston, you can ensure that your network security is strong. But to better protect your network, it would be helpful to know about the issues it might be facing as well. Below are some of the common issues you should be aware of and ways to fix them.

1. Ransomware


It is one of the most dreaded and unpredictable network security issues as it causes costly damage to businesses. Usually, attackers infect systems, encrypt data, and threaten to delete or corrupt files if they don’t receive an expensive ransom.

The best way to defend against and resolve ransomware is to use anti-virus software, educate team members to distinguish phishing attacks, and update your system’s security patches. To minimize the impact, focus on the importance of network security and create a solid recovery and backup strategy.

2. Insufficient Network Security Team

Another common network security issue for many companies is that even when they have the best cybersecurity solutions, their team may not have enough staff to properly manage those solutions. Once this happens, your team may miss some critical cybersecurity alerts and cyberattacks may not be prevented in time to reduce damage.

Finding enough people for your internal network security team to handle your needs can be time consuming and expensive. Take note that most qualified professionals are in high demand. Working with a dedicated partner who offers quality services or solutions would be a good option to build a team that can quickly handle your network security issues.

3. Unknown assets on your network

More often than not, most companies do not have a complete inventory of digital assets tied to their network, which can become a major issue over time. If you have no idea what your network assets are, how can you keep it safe?

The best possible solution for this is to go through all the devices connected to your network and determine the different platforms they use. Once done, you will know the access points in your network, which will help you determine which ones need security updates.

4. Insider Threats

Today, most attacks are actually carried out by insiders. Whether it’s misuse of account privileges, intentional leaks, honest mistakes made by sending information to the wrong email addresses, or identity theft due to a phishing campaign that compromises user account data, your team members could be one of the security issues you will face.

Since insider threats come from trusted systems and users, they are also the most difficult to stop and identify. However, there are ways to reduce your risk in the event of insider attacks. For example, if your company uses a policy of least privilege (POLP) for user access, you can limit the damage that misused user accounts can cause. In this type of strategy, users’ access to the various databases and systems on your network is limited to what they need to do their jobs.

5. Lack of Defense

Lack of defense is another common network security issue. You must remember that despite your best efforts, attackers can manage to breach your network security. But the damage they can cause may depend on the security of your network. For this reason, you may need a multi-layered defense.

Usually the problem is that several companies have an open network structure where attackers are in the trusted system, giving them access to systems in your network. If your network has strong segmentation to keep its discrete parts separate, it is possible to slow down attackers enough to keep them away from crucial systems. At the same time, your security team can work to identify, contain, and eliminate the breach.

6. Unpatched security vulnerabilities


Most companies worry about zero-day exploits, which are unknown security issues in systems and programs that haven’t been used against anyone yet. But a zero-day vulnerability is not the problem. The main issue is a known, unpatched vulnerability.

The easiest solution to this network security issue is to adhere to a strict security patch schedule. Gradually changing the operating systems and programs on your network to make them the same can simplify the whole process. For example, if all of your systems are Mac- or Windows-based, you should follow those operating systems’ security patch alerts and schedules.


Network security issues can arise at any time. The good news is that there are ways to fix them immediately. As long as you are armed with network security knowledge, you can be prepared for the inevitable. If you think you can’t handle the situation, don’t hesitate to work with network security experts to get the best possible solutions to the problem.
