Ransomware is undoubtedly one of the most harmful types of virus attacks for any corporate network. When a computer system is infected with the malware, it locks down all the files stored on the local hard disc, demanding a certain amount of ransom from the victim to get access to the data. Over the last few years, ransomware attacks have increased and have become a lot more targeted. Therefore, you need to stay proactive and protect your network from getting infected with this malware.

Here are some steps you need to take to ensure that your network is ransomware proof:

Perform Regular Backups

Though this is the most basic defense against ransomware, performing regular backups goes a long way in minimizing the consequences you have to face in the event of an attack. Create and implement a policy that requires the employees to backup their files at frequent intervals. When you have a copy of the files, your business activities would not be hampered due to a ransomware attack.

Disable Remote Access

In most cases, ransomware exploits the vulnerabilities in the computer systems or mobile devices used to access your network remotely. Though remote access allows employees to work from anywhere, it also increases the chances of a hacker being able to infiltrate the corporate network. Therefore, you should disable remote access, particularly on the systems where it is absolutely not required.

Deploy A Firewall

Install a reliable firewall software to prevent ransomware from getting access to your network. When you have set the rules on what type of content can or cannot be accessed on a computer system, you can significantly limit your network’s attack surface. It will also scan all the file downloads in real time and block the ones that potentially contain a malicious code.

Setup correct file and folder level permissions

Just like a firewall software protects you from external attacks, setting up file and folder permissions is important to secure your network internally. Make sure that the employees have access to only those files which they need to perform their tasks. For instance, marketing employees should not be able to view, modify or share the HR department folder. This will not only provide protection from ransomware, but lead to a more secure network environment on the whole.

Continuous network monitoring is one of the core elements of maintaining a secure and efficient IT infrastructure within an organization. As network systems have evolved over the past few years, it is essential to manage the configuration of all the network devices, servers and services to ensure timely detection as well as removal of the potential threats.

Given below are some of the tips for implementing a successful network monitoring strategy:

Note the baseline network performance

In order to identify any problems in the network infrastructure, it is important that you have an idea about its normal performance. Documenting network functionality over a period of time can help you to set accurate thresholds and receive alerts when the network is not performing up to the mark. Base-lining also facilitates proactive troubleshooting and prevention of downtime before it causes problems to the users.

Inventory management

You need to have an in-depth understanding of the IP devices, routers, switches and servers that make up your network. Make a detailed inventory of all the items you need to manage and add them in your network monitoring software. Categorize all devices on the basis of usage, vendor, location, data center and other parameters. Create a map and form connections between the system so that it represents your network architecture. This will give you a visual idea about how the inventory should be maintained.  

Monitor and report at every level

Every element in diverse corporate network operates on a separate layer to contribute to its overall functionality. In the event of a system failure, it is critical to identify the layer at which the data connection has been interrupted. Therefore, your network monitoring system should focus on observing and reporting problems at all layers. This will make it easy for you to detect if the issue has been caused due to malfunctioning of hardware, router, bandwidth or any other component.

Prepare for network expansion

With the expansion of your organization, your network also needs to evolve and incorporate new technological upgrades. This, in turn, will also increase the number of devices, network bandwidth and storage space required. Therefore, make sure you choose a scalable monitoring system that allows you to include more devices and interfaces as and when they are added to the network.
