Protect Against Ransomware Also With Protection
Updated on October 21, 2022, by Xcitium
How to Protect Against Ransomware
To protect against ransomware, organizations should use layered cybersecurity defenses including endpoint protection, offline backups, phishing prevention, zero trust access controls, multi-factor authentication (MFA), employee security training, and real-time threat detection. Effective ransomware protection also requires continuous monitoring, patch management, and rapid incident response capabilities.
Ransomware is a multi-million-dollar cybercrime that strikes both individual users and businesses. Hackers use ransomware to encrypt your computer or critical files until you pay a ransom. It’s such a profitable cyberattack that traditional cybercriminals are dropping their old tactics of making money by stealing credit card numbers and banking credentials—in favor of ransomware.
Ransomware targets businesses or organizations that depend on daily access to critical data. Those organizations which can’t afford to lose access to their valuable data during the time it would take to respond to a ransomware attack are at high risk. This includes large corporations, banks, government agencies, etc.
Individual users are also at risk of ransomware attacks. Below are some of the steps you can take to protect against ransomware.
10 Best Practices to Protect Against Ransomware
- Maintain offline and immutable backups
- Enable multi-factor authentication (MFA)
- Train employees to recognize phishing emails
- Patch operating systems and applications regularly
- Use advanced endpoint protection
- Restrict administrative privileges
- Implement zero trust security architecture
- Monitor networks for suspicious behavior
- Segment critical systems and networks
- Create and test an incident response plan
Protect Against Ransomware: Back Up Your Critical Data on a Regular Basis
The leading defense against ransomware attacks is by taking normal backups of your data. By this way, you don’t get to worry about the threats postured by ransomware. Even in case your systems or files get encrypted, you don’t have to pay to ransom to see your data again.
Some ransomware variants search and encrypt backup systems too. Such ransomware variants gain entry to a computer system and then manually work their way through the network to get to servers.
So if you back up your data on a local storage device instead of a network shared drive, you can protect your data from ransomware. Ransomware or the cybercriminals behind that ransomware can’t reach your local storage device since they stay offline most of the time (not directly connected to computer systems).
Protect Against Ransomware: Avoid Suspicious Emails and Links
One of the primary methods by which ransomware infiltrates a system is through phishing attacks. When a user opens a malicious attachment in a spam email or clicks on a malicious URL, ransomware gets installed on their machine.
Cybercriminals have also adopted another method known as malvertising to spread ransomware. In this method, Advertiser’s network gets compromised, and it delivers ransomware through the ads. When you click on such malware-embedded advertisements, ransomware infiltrates your computer. You can prevent ransomware by avoiding such emails and links.
Why Backups Are Critical for Ransomware Protection
Ransomware attackers increasingly target backup systems to prevent recovery. Organizations should maintain:
- offline backups
- encrypted backups
- immutable storage
- cloud disaster recovery systems
- regularly tested restoration procedures
Air-gapped and immutable backups help organizations recover data without paying ransom demands.
How Ransomware Attacks Work
Most ransomware attacks follow these stages:
| Stage | Description |
|---|---|
| Initial Access | Attackers use phishing emails, malicious downloads, or exposed RDP |
| Execution | Malware installs silently on the device |
| Privilege Escalation | Attackers gain deeper system access |
| Lateral Movement | Malware spreads across the network |
| Data Encryption | Files and systems are encrypted |
| Extortion | Attackers demand payment and may threaten data leaks |
Zero Trust Security for Ransomware Prevention
Zero trust security helps prevent ransomware by continuously verifying users, devices, and applications before granting access. Unlike traditional security models, zero trust assumes threats may already exist inside the network and limits unauthorized lateral movement.
Key zero trust principles include:
- least privilege access
- identity verification
- device trust validation
- microsegmentation
- continuous monitoring
Common Ransomware Infection Methods
| Attack Vector | Description |
|---|---|
| Phishing Emails | Malicious links or attachments |
| Remote Desktop Protocol (RDP) | Exploited remote access services |
| Software Vulnerabilities | Unpatched applications and systems |
| Drive-By Downloads | Malicious websites and downloads |
| Supply Chain Attacks | Compromised third-party software |
What to Do During a Ransomware Attack
- Isolate infected systems immediately
- Disconnect compromised devices from the network
- Activate the incident response plan
- Identify the ransomware variant
- Restore systems using clean backups
- Notify security teams and stakeholders
- Conduct forensic investigation
- Patch vulnerabilities and strengthen defenses
Antivirus vs Ransomware Protection
| Feature | Traditional Antivirus | Modern Ransomware Protection |
|---|---|---|
| Signature-Based Detection | Yes | Yes |
| Behavioral Analysis | Limited | Advanced |
| Zero-Day Detection | Weak | Strong |
| Rollback Ca pabilities | Rare | Common |
| Lateral Movement Detection | No | Yes |
| Real-Time Threat Hunting | Limited | Advanced |
Protect Against Ransomware: Patch Your Systems And Applications
Many ransomware attacks are based on known vulnerabilities in software applications, as well as in operating system and plug-ins. Therefore it is critical for you to patch your software applications as and when the patches are available.
The ever-evolving cyber threats landscape ceaselessly presents modern challenges. Ransomware is one of those challenges. Indeed organizations that exercise ideal cybersecurity practices may fall prey to ransomware attacks.
With that in mind, our engineers at Xcitium have deigned Xcitium Advanced Endpoint Protection (AEP). Unlike other endpoint protection software that follows “Default Allow” security posture, Xcitium AEP uses “Default Deny” security posture. Along with it, it uses powerful Containment engine which can quickly contain both known and unknown (new) malicious software including ransomware.
Xcitium AEP is a complete endpoint protection platform that can disarm even the potent malware such as the ransomware. Get Xcitium Advanced Endpoint Protection today and secure your endpoints against ransomware and other malware threats.

Frequently Asked Questions
What is the best protection against ransomware?
The best protection against ransomware includes layered security controls such as endpoint protection, backups, MFA, employee training, and zero trust architecture.
Can antivirus stop ransomware?
Traditional antivirus alone is not enough. Advanced ransomware protection requires behavioral analysis, threat detection, and real-time response technologies.
What are signs of a ransomware attack?
Common signs include encrypted files, ransom notes, unusual system behavior, inaccessible data, and suspicious network activity.
Should companies pay ransomware demands?
Law enforcement agencies generally discourage paying ransom because payment does not guarantee data recovery and may encourage future attacks.
How do backups help against ransomware?
Backups allow organizations to restore encrypted data without paying attackers.
