Logout5 Common Network Security Problems and Solutions
- Problem #1: Unknown Assets on the Network.
- Problem #2: Abuse of User Account Privileges.
- Problem #3: Unpatched Security Vulnerabilities.
- Problem #4: A Lack of Defense in Depth.
- Problem #5: Not Enough IT Security Management.
Problem #1: Unknown Assets on the Network
There are many businesses that don’t have a complete inventory of all of the IT assets that they have tied into their network. This is a massive problem. If you don’t know what all of the assets are on your network, how can you be sure your network is secure?
The easiest fix for this is to conduct a review of all the devices on your network and identify all of the various platforms they run. By doing this, you can know what all of the different access points are on your network and which ones are most in need of security updates.
Problem #2: Abuse of User Account Privileges
According to data cited by the Harvard Business Review, for the year of 2016, “60% of all attacks were carried out by insiders.” Whether it’s because of honest mistakes (accidentally sending info to the wrong email address or losing a work device), intentional leaks and misuse of account privileges, or identity theft arising from a phishing campaign or other social engineering attack that compromises their user account data, the people inside your business represent one of the biggest security problems you’ll ever face.
Problem #3: Unpatched Security Vulnerabilities
Many businesses are concerned with “zero day” exploits. These exploits are those unknown issues with security in programs and systems that have yet to be used against anyone. However, zero day vulnerabilities aren’t the problem—unpatched known vulnerabilities are the problem.
As noted in one CSO online article, “around 6,300 unique vulnerabilities appeared in 2015. Symantec says that only 54 of them were classified as zero-days.”
This is because when a “zero day” exploit is used it can be discovered—becoming a known issue that the software vendor can begin working on. The more often the exploit is used, the more likely it is to get discovered and patched. Also, it takes a lot of effort to independently discover a completely unknown vulnerability in a system.
Problem #4: A Lack of Defense in Depth
Eventually, despite all of your best efforts, there will be a day where an attacker succeeds in breaching your network security. However, just how much damage this attacker will be capable of depends on how the network is structured.
The problem is that some businesses have an open network structure where once an attacker is in a trusted system, they have unfettered access to all systems on the network.
If the network is structured with strong segmentation to keep all of its discrete parts separate, then it’s possible to slow down the attacker enough to keep them out of vital systems while your security team works to identify, contain, and eliminate the breach.
Problem #5: Not Enough IT Security Management
Another common issue for many companies is that even when they have all of the best cybersecurity solutions in place, they might not have enough people in place to properly manage those solutions.
When this happens, critical cybersecurity alerts may get missed, and successful attacks may not be eliminated in time to minimize damage.
However, finding a large enough internal IT security team to manage all of your needs can be an expensive and time-consuming process. Qualified professionals are in demand, and they know it.
To build up IT security staff quickly, many businesses use the services of a dedicated partner such as Compuquip Cybersecurity. This allows these businesses to access a full team of experienced cybersecurity professionals for a fraction of the cost of hiring them full-time internally.
