Ransomware is becoming a main hazard to computer systems in some Managed IT Services in Australia. It is a powerful method of attack that offenders use to infect computers and block the users from retrieving their own data, unless they pay a ransom. It is not a new threat; but, it has become more widely used by offenders because they can gain profit from it.
Here are some guidelines to help prevent being infected by Ransomware:
Assess Backup Process
One of the most useful ways to recuperate from a ransomware attack is to have a complete and updated backup. You must frequently check your backup processes to make sure that all important data are being backed up in a timely manner.
Examine Incident Response Process
You must cultivate a complete incident response process, which includes how to deal with ransomware attack. This process must contain how incidents are prioritized, documented, and escalated where needed.
Execute a Cybersecurity Awareness Activity
Technical controls may not identify and control all ransomware, particularly given the fast changing nature of these risks. During this time, the last line of defense is the end user – who accepts the email or browses the web. Thus, it is important that all handlers are well authorized to recognize security risks and handle them accordingly.
You must examine your recent security awareness activity program to certify that it is properly resourced and that it targets all users. While technical controls may reduce the risk of various threats, the human factor must be continuously managed. If all employees in your IT Services in Melbourne are not mindful of the risks to their systems or how to respond to a suspicious security breach, then the risk of a security breach taking place rises ominously.
Update Your Anti-Virus Software
You must ensure that all computers or laptops have the latest anti-virus software installed and that they are frequently updated with the newest software updates and security features. Moreover, you must guarantee that the anti-virus installed in all your computers or laptops has all the anti-malware features applied so that any unfamiliar activities that may show an infection can be quickly recognized.
Restrict ActiveX in Your Files
You must restrict ActiveX content in your Microsoft Office applications. A lot of computer viruses use functions to take advantage of ActiveX and transfer malware onto the affected computer. This would be mostly recommended to any businesses running devices with any Microsoft operating system earlier than Windows 10.
Upgrade Your Operating System
You must upgrade computers to the latest version of Microsoft Windows. Today, Windows 10 Professional is considered to be one of the most protected desktop operating system.
Execute Network Segmentation
You may want to consider segmenting your network to lessen the chance of risks – whether from ransomware or other threats – to spread quickly from one system to another. This will provide you the capability to remove infected segments of the network and prevent the infection from increasing.
Operate Constant Phishing Examinations
You must operate regular phishing simulations to determine how many would possibly fall victim to such a threat. A phishing simulation is a device to send fake emails to employees with an attachment or link to determine how many of your employees would click on the attachment or link. Since most ransomware threats are the result of phishing emails, this type of examination, combined with an actual cybersecurity awareness activity, may be somehow effective in training your employees not to trust all emails and to be careful when dealing with emails.
