In this article I will discuss how virtual patching solutions can help your company to better protect its most valuable asset: its network. Although firewalls and antivirus programs are very effective at stopping hackers from invading your network, they are not always reliable or effective in correcting errors and vulnerabilities that might be present. Many of these errors and vulnerabilities can be completely hidden. This means that hackers may be able to use a vulnerability to gain access to your network without your knowledge or approval.
Many businesses are choosing to implement virtual patching solutions for several reasons. One of these reasons is to reduce the cost of patching servers for critical systems. By separating critical system software from non-critical systems, virtual patching solutions can be more cost effective. Each system on your network should have its own patch software and it should be updated whenever there is a vulnerability found or an error created. This way you can ensure each machine has the correct software and can be updated at any time.
The second reason companies are using virtual patching solutions is because they allow you to better manage the distribution of patches. Because there are only a handful of machines on your network that need to be patched every time there is a vulnerability discovered, it is easy to distribute patches across your network in batches. You can determine the number of patches to put out based on current usage. By putting out fewer patches, you reduce the risk of your network being penetrated as well as reducing the time it takes to resolve the problems.
It is also possible to use virtual patching solutions to address application vulnerabilities. This can come in the form of patching your application servers, database, or any other vulnerable application that makes your network vulnerable. By isolating each vulnerability and distributing the patch over your entire network, you can greatly reduce the number of security issues that make your system vulnerable.
While many people use virtual patches as a form of prevention against security issues, there are a few instances where virtual patches can help you better secure your network. If your company has several data centers, each with their own network of servers, you can install the patches on each server separately. For this very purpose, it is often easier to use virtual patching solutions. Since the patches are contained only within the software and can’t be pulled by hackers from a stand-alone computer, there is less risk of the vulnerability becoming known and of the threat spreading.
The last reason companies choose to use virtual patching solutions is to address security issues that arise from poorly designed security policies. When a company allows all computers in a network to connect freely to the internet, it opens the door for a variety of security issues including denial of service attacks, which send numerous spoofed online attacks to a single server. By using the latest technology, a company can ensure that its most secure networks remain so, by applying a virtual patch that prevents a variety of security problems from occurring.
Because many companies don’t always understand the vulnerabilities that their networks contain, it can be difficult for them to determine what they should do in the event that a vulnerability is found. In many cases, it is also difficult for IT professionals to pinpoint exactly which security issues may exist, and what they mean to the overall security posture of the network. However, by using virtual patching solutions, it is easy to see all of the vulnerabilities that exist on your network and what the easiest way to remedy them would be. Without the patches, your network would still be vulnerable, since the issues would be unknown to you.
A good example of how a web application firewall can help a company prevent vulnerabilities is when a hacker finds a hole in one of the software’s security measures and creates a hole in your network. By implementing a complete web application firewall, you can close the security hole before any viruses or other malware can make it into your network and begin executing on it. Since you never have to actually install any patches over the air-garden, your company can save a lot of money in the process, since the price of having a complete security solution in place is much less than the cost of purchasing and maintaining a large number of costly patches. If you want to protect your business, consider adding virtual patching solutions to your overall security plan.
