Many IT administrators struggle to protect their company’s server from malware, and one of the most common malicious software that can damage your IT setup is ransomware.
Ransomware is hacking software that cybercriminals use to hold the IT system hostage. If the user of the IT system refrains from paying the ransom that is demanded by the cyber criminals, then your system controls will remain in their possession and you will be left without access.
There are several different ways in which this malware can enter your computer. Below are some tips that can be followed for protecting your IT system.
1. Update backup databases regularly
One of the most effective strategies that companies can follow to protect their servers against such attacks is to have backup databases.
If a backup is created, then you can start your work again easily. In addition to having a backup, the files on the server can be encrypted, so that other users are unable to access the information or use it for other purposes.
Many IT experts recommend companies to transfer data to an external source in the absence of an online connection. This helps in preventing malicious code files from entering the computer software.
2. Check extensions before opening the file
Ransomware can enter the IT system through an extension file that is uploaded.
If the file has been uploaded to the cloud – where the database is kept – then the entire information can be damaged by the malware. Most of the operating systems hide the file extension, which makes it difficult for individuals to check the file’s status and origins. Therefore, IT administrators need to check the extension of any file that they upload to the company’s server.
3. Filter files
Some of the ransomware files can enter your IT setup through emails. In fact, 91% of advanced cyber attacks begin with an email.
To prevent an attack, you need to install a malware filter in the company. Through the filter, the company can check if a particular extension file with suspicious coding pattern has been sent to a company’s email address.
At times, these executable files are sent with normal files, so that the users are unable to detect a problem. Companies can send safe executable files in a compressed folder, so that the files are not immediately opened upon download.
4. Have a system restore option in place
If the company servers have system restore option enabled, then they can get their data cleaned off any harmful coding.
Users need to carefully handle suspicious files, as ransomware can delete shadow files that are used for system restore. Ransomware starts deleting restore files as soon as the executable file is opened. Therefore, it is important to think of a cybersecurity strategy when a suspicious executable file starts working on the computer.
5. Reduce connectivity to the Internet
If you observe that an incorrect and possibly harmful file has been opened, then you need to immediately disconnect the computer from internet access.
This helps in stopping the ransomware file from making contact with the server, so that it can encrypt files on the computer. In some instances, if there is an anti-malware software or firewall installed in the computer, then it can immediately alert you if potentially dangerous executable files are opened by the user.
