Network engineers are technical experts with the skills necessary to plan, implement, and monitor computer networks that support voice, data, video, and wireless services within the company.
The terms Network Engineer and network administrator are sometimes used interchangeably, but the network engineer generally has more responsibility than the network administrator. The engineering side of things tends to be more about planning, design, and technical specifications, while the management side of things focuses on daily maintenance, management, and problem-solving efforts.
Titles can also be distinguished by education and income. Network engineers are often more educated and earned than network administrators.
5 Common Network Security Problems and Solutions.
Many companies experience numerous network security problems that don't actually happen. Worse still, if these issues are not resolved, an attacker could compromise the corporate security infrastructure and steal data, wreaking havoc.
There are too many potential problems to elaborate on an online publication. Therefore, this article describes the most common network security problems and how to solve them.
Problem # 1: Unknown Asset On The Network
There are many companies that do not have a complete inventory of all the IT assets linked to their network. This is a big problem. How can I make sure my network is secure if I don't know all the assets?
The simplest solution to this is to check all the devices on your network and identify all the different platforms they run on. This will give you an idea of all the different access points on your network and which ones require the most security updates.
Problem # 2: Exploiting User Account Privileges
According to data cited in the Harvard Business Review, "60% of all attacks were perpetrated by experts" in 2016. An honest mistake (incorrect sending of information to the wrong email address or loss of your working device), disclosure Intentional or misuse of account privileges, user account data from phishing campaigns or other social engineering attacks. People within your business, such as identity theft due to rapes, represent one of the biggest security issues you will face.
Because these threats originate from trusted users and systems, they are also one of the most difficult to identify and stop.
However, there are ways to minimize the risk in case of internal attacks. For example, if your company uses a Least Privilege Policy (POLP) for user access, you can limit the damage caused by misuse of user accounts. With POLP, everyone's access to the various systems and databases on the network is limited to what they need to do their jobs.
Problem # 3: Security Vulnerability Not Patched
Many companies are concerned about "zero day" abuse. These exploits are unknown issues regarding the security of programs and systems that have not yet been used by anyone. However, zero-day vulnerabilities are not an issue. The problem is a known vulnerability that has not been patched.
As I mentioned in a CSO online article, "About 6,300 unique vulnerabilities occurred in 2015. According to Symantec, only 54 were classified as zero-day."
This is because the use of "zero day" exploits is a known issue that software vendors can start working on and can discover. The more exploits are used, the more likely they are to be discovered and patched. It also takes a lot of effort to uniquely discover completely unknown vulnerabilities in the system.
Therefore, attackers generally prefer to use known exploits. In fact, as noted in the OSC article, "Verizon Data Breach Report 2016 revealed that most of the vulnerabilities detected were due to vulnerabilities through 2007. The next one is 2011. It was."
Problem # 4: Lack Of Complete Protection
In the end, the day will come when attackers can successfully compromise network security, despite doing their best. However, how much damage this attacker can do depends on the structure of the network.
The problem is that some companies have an open network structure where an attacker can log in to a trusted system and have free access to all systems on the network.
If your network is structured with strong segmentation and separates all the different pieces, slow down attackers to prevent them from entering critical systems while security teams identify, contain, and eliminate breaches. There's a chance.
Problem # 5: Inadequate It Security Management
Another problem common to many companies is that, even if you have all the best cybersecurity solutions, you may not have enough people to manage them properly.
When this happens, critical cybersecurity alerts are lost and successful attacks are not eliminated in time and the damage cannot be minimized.
However, finding an internal IT security team large enough to handle all of your needs can be a costly and time consuming process. Qualified professionals are in demand and know it.
To rapidly grow their IT security staff, many companies rely on the services of dedicated partners like Compuquip Cybersecurity. This gives these companies access to a full team of experienced cybersecurity experts for a fraction of the cost of hiring full-time at the company.
Some companies use these cybersecurity solution partners to strengthen their IT security department in the short term while preparing their internal cybersecurity team.
