How to prevent a ransomware cyber attack
We are currently part of the ongoing digital revolution that continues to digitalise our society and how we conduct business. Data is becoming increasingly more important to us and acts as a catalyst of growth in addition to the concept of ‘big data’ taking stage in the cyber security environment.
2.5 quintillion bytes of data are created every day
As a result, higher volumes of sensitive data are stored and generated on internal assets as organisations continue to strive to be more technologically advanced and efficient.
But what are the consequences of such a world?
Ransomware is identified as malicious software that uses encryption to hold sensitive data and exploit computer software. In return – it’s victims are forced to submit funds to restore and retrieve their inaccessible data.
As ransomware technology evolves and attackers become more diligent and skilful, these kinds of cyber-attacks are becoming harder to detect as malware has gained a more powerful and hovering presence within data security.
We need to become a more united force and put more into preventing these malicious ransomware attacks. Here are a few simple steps your enterprise should take to be one step ahead:
Educate your workforce
- This may seem like one of the most obvious steps but many businesses consider this a low priority and don’t take the time to educate their workforce on how to sport ransomware attempts. Cyber-attacks can be cut short by employees understanding when a phishing attempt is in view. The simple act of knowing not to click on risky links or attachments and understanding these typical conventions of a scamming email can prevent a cyber breach altogether.
Segregate systems and assets
- Having an effective segregation system in place that separates different systems and assets can be a strong defensive mechanism. If an individual does initiate a spamming attempt, having these types of systems will prevent the virus from spreading throughout other areas of the network.
Have strong, Threat Intelligence software
- It’s essential to ensure you have robust detection tools in place enhanced by threat intelligence to detect and respond to infections. Scam attacks can then be found quickly with the appropriate action taken immediately to minimise impact. Having a strong, reputable antivirus implemented can hold off a ransomware attack.
Always keep a secure backup
- One of the worst impacts of a breach is the loss of important documents. Don’t neglect your back-up process and continue to save data and files in the case of an unforeseen cyber-attack. If breached, it’s better to wipe all computer systems and then reinstall a trusted backup. Save a back-up on an external device that isn’t connected to the internet and consider used cloud services. You can then restore any impacted files from a previous backup.
- Ensure that software downloads are a priority to keep your system up-to-date and fix any vulnerabilities that could leave your data a target. Always download the newest version of software you use within your business as soon as it’s available to ensure security is tight. Regularly look for patches within software to help prevent infection.
- Do not release sensitive information through email platforms. Having filters on your mail servers that can recognise and ignore spam can improve security by content scanning incoming e-mails for threats and risky attachments. If in doubt, always contact a member of your IT department or a co-worker if you deem anything suspicious.
