From spyware that observes and records online activity to ransomware that encrypts company data to leverage payments, there are a wide range of different malware attacks aimed at enterprises. The aim of a malware attacks can simply be to corrupt systems and data. Or, it may be more insidious and involve the theft of confidential information or compromising company devices to use in strikes against other firms.
While malware attacks are a prevalent problem for cybersecurity teams and systems admins at enterprises of all sizes in a wide range of sectors, it is possible to become prepared for possible attacks. In this blog, we’ll detail some key measures that every firm must consider adopting to defend against this threat.
Back up data
Malware attacks are notorious for making data inaccessible to users. Whether it takes the form of computer virus, worms that make information unusable or a ransomware attack that locks enterprises out their systems and files through encryption, being able to restore resources is invaluable.
To this end, ensure that your system is automatically backing up all the data you use as well as your operating systems and stored files. Ensure that a fresh set of data is always kept off-site or in the cloud and well-secured. As a result, if your systems become infected you can remain resilient by restoring your data from clean back-ups.
Maintain rigid update regimens
When software or operating systems receive an update, it is important to install the upgrade immediately. Updates issued by software, application and operating system manufacturers contain important security fixes and patches for known vulnerabilities.
When users fail to update their systems, threat operators can use these system vulnerabilities to gain a foothold on a company network and deploy malware. The best policy is to automate updates so that systems and applications are immediately upgraded and always running the most secure version.
Prevent malware delivery
One of the main paths that malware uses to infect business devices and systems is via email phishing attacks. Use secure filtering systems to blacklist known threat actors and protect employees from phishing traps. It is understood that some well-crafted attacks may still penetrate your defences, so ensure that you install anti-malware on company devices that will isolate infections and stop them spreading throughout your network.
Educate your team on how to identify a phishing email and drill them on best practices for email security. Staff must know to never click on links or download attachments from unknown senders and that they must report malicious emails immediately to IT security. Training staff turns each member of your team into an effective cybersecurity tool and can prevent malware attacks.
