Ransomware Attack Prevention: Steps On How To Prevent This

By: Osinachi
Published: April 2, 2022

Ransomware attacks are becoming a major issue in virtually every sector and at all levels of business. Federal authorities in the United States have described it as one of the country’s most dangerous challenges. Perpetrators have targeted institutions, shipping companies, healthcare groups, drug research, and more in recent years. Given the potential for these attacks to have a global impact, security researchers must rethink how they defend their systems, communications, and software.

Ransomware is a sort of virus that prevents users from accessing a system, device, or document until they pay a ransom. Ransomware accomplishes this via encrypting files on the backend, demanding to delete files, or preventing access to the network. Ransomware attacks against hospitals, emergency call centres, and other important infrastructure can be highly troubling.

What Is The Definition Of A Ransomware Attack?

Ransomware is a form of the virus that encrypts information in exchange for a ransom payment. It has the ability to cause significant harm as a means of assault. Phishing emails are a typical way for ransomware to be transmitted, but it may also be propagated via drive-by downloads, which occurs when a customer accesses a malicious site. Sophisticated assaults penetrate devices in seconds, and ransomware attacks harm your systems and infrastructure in seconds.

Hence why it’s crucial to make sure your company is ready. As ransomware assaults get more sophisticated, the consequences go beyond economic losses and lost productivity caused by downed networks.

Attempts at attacks and data compromises are unavoidable, and no business aims to be compelled to choose either paying a ransom or sacrificing critical information. Thankfully, those aren’t your only choices. The wisest course of action is to avoid being compelled to make that choice in the first place. This strategy necessitates a tiered security model that combines proactive global threats intelligence-driven networks, endpoint, program, and data-centre measures.

We take a deep dive into ransomware, including what it really is, how to prevent it, and what to do if you become a target.

The Most Important Things To Remember In Order To Avoid Ransomware Attacks

1. Data Backups

All of your systems and data should be backed up and stored off the network for your firm. These backups must also be examined to guarantee that they can be restored correctly.

Nevertheless, there are several factors to look at. Your backup copies should be properly safeguarded and saved offline or out-of-hand so that hackers cannot access them. Many cloud providers keep prior copies of files, enabling you to scale back to an unlocked copy in the event of a ransomware infestation. Always be careful to test backups for reliability on a regular basis. Whenever scaling back in the event of an attack, be sure your backups aren’t contaminated.

2. Endpoint Device Security

Popular antivirus programs aren’t always effective, and they can’t consistently catch up with evolving attacks. Using an endpoint detection and response (EDR) solution and other technologies, businesses must ensure that endpoint devices are properly protected.

Innovative assaults can infect endpoints in minutes or seconds in today’s threat landscape. Since manual inspection and replies are required, first-generation EDR technologies simply cannot keep up. They’re not only too slow for today’s lightning-fast attacks, but they also create a huge number of warnings, which adds to the workload of already overburdened cybersecurity teams.

Next-generation EDR technologies, on the other hand, provide enhanced, real-time threat information, transparency, assessment, control, and control for endpoints – both before and after they have been infected with ransomware. These EDR solutions can identify and neutralize possible threats in real-time, reducing the system vulnerabilities and assisting in the prevention of malicious programs, as well as automating action and cleanup operations.

3. Ensure That Your Systems Are Up To Date.

Ensure that all of your company’s operating servers, apps, and data are kept up to date. By installing the most recent updates, you may help close the security flaws that cybercriminals are attempting to leverage. Turn on auto-updates whenever possible to ensure that you have the most recent security fixes.

4. Email and Sandbox Testing

Amongst the most common attack routes for malicious attackers is email. Advanced comprehensive security against the complete spectrum of email-borne dangers is provided by a secure email gateway system. Sandboxing adds an extra degree of security. Before it hits your system or mail server, any email that surpasses the email filter but still has unidentified hyperlinks, senders, or file kinds can be examined.

5. Security And Firewall Technologies For Web Applications

By screening and monitoring Network access to and from a webserver, a web application firewall (WAF) aids in the protection of web apps. It serves as the initial layer of defense towards cyberattacks, making it a critical security component. Organizations frequently enhance the attack surface when they implement new digital projects. Online server flaws, server extensions, and other flaws might expose new web applications and application programming interfaces (APIs) to harmful data. A WAF aids in the security of these applications and the information they handle.

6. Sharing Of Threat Intelligence

To help prevent unknown dangers like FortiGuard Labs, organizations need real-time valuable intel. To create a preventive response, information must be communicated between the many encryption techniques and devices in your system. Additionally, this information sharing must apply to the entire cybersecurity sector outside of your firm, such as CERTs, ISACs, and industry alliances like the Cyber Threat Alliance. The only approach to effectively respond to threats and terminate the cyber death cycle before it evolves or extends to other networks or businesses is to share information swiftly.

7. Integration Of Minimal Trust

Anyone or everything attempting to gain access to the network is assumed to be a viable threat in the zero trust concept. Nobody inside or outside the network should be authorized except their identity has been thoroughly examined, according to this network security theory. Threats from both the outside and inside the system are pervasive, according to zero trust. These beliefs shape network managers’ thinking, forcing them to devise rigorous, untrustworthy safety mechanisms.

When using a zero-trust strategy, every person or machine attempting to access the system or software must go through rigorous proof of identity before being permitted entry. Multifactor authentication (MFA) is used in this validation, which enables users to give multiple credentials before being permitted permission. Network Access Control (NAC) is another component of zero trust, and it is used to prevent unwanted people and devices from gaining entry to a corporate or private network. It guarantees that only validated people and machines are allowed access to the network, as well as that they are compliance with security regulations.

8. Spam Blocker

Malicious hackers send thousands of dangerous emails to random companies and people, but a good spam filter that improves over time, along with a cloud-based security intelligence center, can block well over 100 percent of them from accessing personnel’ computers.

9. Set Up An IDS.

The Intrusion Detection System (IDS) compares network data records to patterns that flag recognized malicious behavior to hunt for harmful activity. An effective IDS will regularly update identifiers and notify your company if it finds potentially dangerous behavior.

Set Up An IDS.

10. Anti-Ransomware Software Should Be Updated

As previously stated, system software must be updated on a regular basis. This is certainly relevant if you already have an intrusion detection and prevention system (IDPs), antivirus, and anti-malware installed.

Numerous security companies offer items that range from emails and network monitoring to intrusion detection and prevention systems (IDPs) and risk assessment technologies. While there are multiple consumer-facing anti-ransomware providers, below is a partial list of suppliers and tools for IT purchasers to consider:

  • Norton

  • Bitdefender

  •  Webroot SecureAnywhere

  •  Malwarebytes

Whereas the solutions listed above provide pre-attack security, an increasing number of companies are searching for fast response features. Coveware, situated in Connecticut, for instance, provides free restoration alternatives, security threat agreements, blackmail resolution, and guarantees that data will be retrieved and disruption will be minimized.

11. Strong Security Passwords Should Be Enforced

Firms must improve their IT privacy to lower the likelihood of cybercriminals effectively breaching systems and private data. Surprisingly, the majority of it begins with basic multifactor authentication.

For every one of your profiles, we encourage you should use complex passwords. At least ten characters with a mix of upper and lowercase letters, digits, and symbols are preferred. Attackers will have a harder time encrypting accessing your profile with this approach, and you’ll be less vulnerable to malicious attacks.

Your account will almost certainly be stolen or auctioned on the dark web if your login is simple and entirely weak. Apart from basic brute force attempts, hackers can also use auxiliary efforts to gain access to the network where the ransomware will be installed.

Multi-factor authentication should be used. Even if fraudsters obtain your passwords, they won’t be able to access the information because the system will demand a second set of verification codes that will be issued solely to your email or cell phone
