How to protect your data from ransomware
Good news is, you’ve got plenty of ways to shield yourself from getting slammed by ransomware. Since tech keeps on changing, it’s smart to stick to the basics of cybersecurity and stay one step ahead. That way, you won’t ever have to worry about ransomware messing with you or your business.
Keep data backups
One of the simplest ways to lower the risk is to back up your data on an external hard drive or in the cloud. If ransomware hits, you can just wipe your computer and bring back the files from your backup. It’s best for organizations to make sure they’re backing up their crucial data at least once a day.
Keep everything up to date
Never slack off on updating your operating system, web browser, antivirus, and any other software you’ve got. Malware, viruses, and ransomware are always changing their game, coming up with new tricks that can slip through the cracks of outdated security features. Keep everything patched and up-to-date to stay on top of the security game.
Lots of attackers go after big businesses that are still hanging on to old-school systems that haven’t seen an update in ages. One of the most notorious ransomware attacks happened in 2017 when this nasty software called WannaCry messed up major companies worldwide. It hit NHS hospitals in the UK, the Spanish telecom giant Telefónica, and even made Apple chip supplier Taiwan Semiconductor Manufacturing Co. (TSMC) slam the brakes on operations for four days. Overall, it wreaked havoc on more than 230,000 computers all over the globe.
Install firewalls and antivirus
The go-to defenses against ransomware are solid antivirus and anti-malware software. They’re like the frontline soldiers that can scan, spot, and tackle cyber threats. But, don’t forget to set up your firewall too. Antivirus software only kicks in once the attack is inside the system, so a configured firewall is like having an extra layer of security at the entrance.
Think of firewalls as the bouncers at the club’s entrance, the first line of defense against any outside attacks. They’re the superheroes that shield against both software and hardware-based threats. Every business or private network needs them—they’re the gatekeepers that sift through and block any shady data trying to sneak into the system.

Email protection in necessary
Throughout history, phishing attacks via email have been the main culprits behind malware infections. In 2020, a whopping 54% of managed service providers (MSP) pointed fingers at phishing as the top way ransomware sneaks in. The Federal Bureau of Investigation (FBI) backed this up, naming phishing scams as the big player in cybercrime for 2020, racking up a massive $4.2 billion in losses and theft.
Steer clear of emails from unfamiliar senders – Resist the urge to open messages from unknown sources and don’t click on attachments, files, or links from unauthorized addresses.
Keep your email client apps up to date – Prevent cybercriminals from exploiting security gaps in outdated technology by making sure your email apps are always current.
Leverage Sender Policy Framework (SPF) – Use this email authentication method to specify which email servers are authorized to send outgoing messages.
Implement DomainKeys Identified Mail (DKIM) – Enhance email security by adding an encryption key and digital signature to verify that the email hasn’t been tampered with, spoofed, or forged.
Activate Domain Message Authentication Reporting & Conformance (DMARC) – Further fortify email authenticity by cross-referencing SPF and DKIM protocols to ensure the legitimacy of incoming messages.
