what are the some remedies for internet security issues?

Answer:
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.
Because these threats come from trusted users and systems, they’re also among the hardest to identify and stop.
However, there are ways to minimize your risk in case of an insider attack. For example, if your company uses a policy of least privilege (POLP) when it comes to user access, you can limit the damage that a misused user account can do. In a POLP, every user’s access to the various systems and databases on your network is restricted to just those things that they need to do their jobs.
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.
So, attackers generally prefer to stick to known exploits. In fact, as noted in the CSO article, “The Verizon Data Breach Report 2016 revealed that out of all detected exploits, most came from vulnerabilities dating to 2007. Next was 2011.”
In other words, vulnerabilities that were almost a decade old accounted for most of the breaches in 2016. Let that sink in.
The easiest fix for this problem is to maintain a strict schedule for keeping up with security patches. Also, gradually changing the programs and operating systems on your network to make them the same can simplify this process. For example, if every system is Windows-based or Mac-based (rather than a hodgepodge of Mac, Windows, Linux, etc.), then you only have to keep track of Mac OS or Windows OS security patch schedules and alerts.
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.
