What is Ransomware Attack, and How Can You Prevent It?

If you’re concerned about the potential ransomware attacks on your computers, you’ve come to the right place. There are several simple things you can do to protect yourself from them.

Multi-factor authentication (MFA)

In the world of ransomware, multi-factor authentication (MFA) is important in preventing an attack. MFA involves requiring two or more independent authentication factors to access a resource. While not unbreakable, it makes it more difficult for hackers to break into an account.

Multi-factor authentication is a security measure that security experts often recommend. It is not without its limitations, however. For example, confusing a phishing scheme with a multi-factor authentication technique can be easy.

When implemented, MFA prevents malicious code from being sent to an individual. Additionally, it can protect an organization’s reputation by deterring cyber exploits.

MFA protects against other types of attacks, such as social engineering. Social engineering is a method of manipulating human behavior to obtain a desired goal. This is a technique that has become a favorite of hackers.

One of the best ways to prevent ransomware is to use a combination of three or more factors to log into your organization. This is very helpful in terms of ransomware attack prevention. These include a password, a one-time passcode, and an authenticator. Each of these will have a different effect.

A password is a relatively simple factor to crack, but it can still be a threat. However, multi-factor authentication adds a few extra steps to the process, making it much more difficult for hackers.

Another benefit of MFA is that it can help deter hackers from gaining remote access to an organization’s systems. Hackers can access an organization’s network through social engineering, phishing, or hacking. If a company does not implement MFA, its security infrastructure may be compromised, and an attacker can easily take control of the business.

Network segmentation

One of the most effective tools for protecting your business from ransomware attacks is network segmentation. This allows you to protect valuable data from unauthorized access. It also helps to prevent the spreading of infection across your entire network.

Ransomware encrypts critical files and denies them access until the victim pays the ransom. The attackers who carry out this attack usually send fake emails and attachments, which are often embedded with malicious code.

For this reason, it is essential to monitor the network. You can use a software-defined policy management system to push policies to all your network devices. These systems allow you to program security policies based on user activity and the location of the data being accessed.

As with any business operation, you should back up your files if an attacker gains access to your network. In addition, you should ensure that your employees understand the threat. They should also patch digital devices.

Another way to reduce the risk of your organization becoming a victim of a ransomware attack is to restructure your network. Segmentation allows you to keep the most critical assets isolated from the rest. It will also improve the performance of your network.

However, you should remember that separating your assets into segments can be complicated, especially if your organization has multiple departments.

Backups

Ransomware is malware that encrypts or deletes your data and holds it, hostage, until a ransom is paid. It’s essential to ensure backups before a ransomware attack occurs.

To prevent a ransomware attack, you need to take two steps: first, make sure you have a backup system in place, and second, implement a plan for restoring your system in the event of an attack. Once you’ve implemented the strategy, you need to monitor it regularly.

One of the best practices is to have a complete backup done regularly. While many companies use Windows for backup, you should consider Linux or other platforms. Keep the backup on a different media than the file server. This will make it harder for a ransomware actor to access your backup system.

For additional resiliency, consider immutable backups. A firm backup means that your data cannot be altered after it has been written. The advantage of this type of backup is that it adds an extra layer of protection against ransomware attacks.

Using the 3-2-1 rule is the general best practice regarding backups. This consists of having a copy of your data on a disk and a copy on a cloud-based service. Many popular backup products also offer a Linux-based media-server option.

Recovering from a ransomware attack

A ransomware attack is a devastating situation for a business. It can damage your reputation, disrupt your services, and destroy your productivity. In addition, the costs can be catastrophic.

One of the most important things to remember is that there are ways to recover from a ransomware attack. The first step is to contain the attack. You can prevent further damage and downtime by isolating the systems affected by the malware.

Another critical step is to back up your data. Having backups helps ensure you have a record of your data in case you are hit by ransomware. Also, ensure your computers are updated with the latest patches and software.

Once you have secured your environment, you can begin the recovery process. Restoring your entire habitat can take a long time. Therefore, prioritize restoration and recovery based on a predefined list of critical assets.

When you have recovered your data, you can re-establish normal business operations. Depending on your business, this may include restoring from backups.

Using a reputable computer security consultant is also a good idea. These professionals can remove the attacker from your system and help you restore your data.

If you have lost files and your company’s information is compromised, it is crucial to report the attack to law enforcement immediately. Ideally, you should have a 72-hour notice. This will allow your business to begin the process of restoring normal operations as soon as possible.
