Threats are rapidly evolving. This has made it crucial for organizations to implement powerful software so that no hackers have the capability to harm an organization’s network. To protect a network from unknown access, firewalls are installed. Over the years, the concept of firewalls has also changed, and there are now a number of firewalls available in the market. Firewalls are categorized into software and hardware firewalls. A software firewall is installed on the desktop, whereas a hardware firewall is a physical device that is installed between a network and connected devices.
All firewalls function in the same way, but UTM software firewalls are quite popular among organizations because of their excellent features. And in UTM software, there are multiple tools that are available to small businesses as well as large businesses. Among all of them comes a very renowned tool, Check Point Firewalls.
In this article, we will discuss in detail what a checkpoint firewall is, how dangerous ransomware is, and what best practices one should implement to protect their network against ransomware.
Check Point Firewall
The Check Point firewall is a famous security solution that acts as a barrier between a private internal network and the public internet. It filters all the incoming and outgoing traffic. With certain features, it can allow or block a specific network from accessing private information.
Features of Check Point Firewall:
· Antivirus and Antimalware protection
To identify threats, Check Point firewalls make use of signature-based detection and behavioural analysis techniques. As soon as it detects the threats, it blocks them to safeguard networks from harmful threats. This shows that Check Point Firewall provides real-time protection against viruses.
· Network Address Translation
This is one of the unique features that differentiates Firewall Partner. NAT translates a private IP address into a public IP address to hide an organization’s network from outside networks.
· Secure Web Gateway
This feature filters the web traffic to prevent users from accessing malicious websites. It automatically blocks a website that is likely to cause harm.
· Sandboxing
Check Point firewalls allow IT administrators to detect untrusted code. It creates a separate environment within a network where one can run the code and check whether it is appropriate or not. It is always considered a safe place where no risk is involved while running suspicious code.
· Stateful inspection
Stateful inspection Technology is used by Check Point Firewall. It tracks all the network connections to ensure that only authorized networks have a tendency to access the network.
· VPN
With the increasing concept of working remotely, it has become quite essential for organizations to install a firewall that can support VPN (virtual private network). A VPN allows registered users to access a corporate network easily from anywhere and at any time. Thus, increasing security.
Importance of Checkpoint Firewalls in Organisations
Those businesses that are new and have not yet installed a firewall are on red alert, as anytime their information can be stolen, which can lead to financial loss, damage to public relations, and legal complications. Therefore, to protect an organization, one needs to install a Check Point firewall, which has all the essential features to safeguard a network from unknown threats. Let us discuss some more of its importance:
1. Secures confidentiality:
Businesses can control the access to their networks by setting up particular rules and policies. This will help them prevent unauthorized access to a network. Thus, securing the confidential information of organizations.
2. Acts as a Gateway:
The Check Point Firewall acts as a gateway between a private and public network. It has the capability to identify and block harmful traffic. Besides, Check Point Firewall uses intelligent algorithms to filter outgoing and incoming traffic. It continuously keeps on analysing the traffic.
3. Secures Communication:
With Checkpoint Firewall, business communication remains secure as it includes the feature of a virtual private network. VPN support allows employees to work from remote locations.
4. Strengthens network infrastructure:
A checkpoint firewall has the capability to detect packets at the application layer to ensure that all network traffic is aligned with the organization’s security policies. This activity prevents unauthorized users from interfering with a private network. Thus, strengthening a network’s infrastructure.
This shows how important it is to install a Checkpoint firewall. It does not only protect against unknown threats but also secures confidential information about organizations. If you want to buy a Check Point firewall, look for various Check Point vendors across India.
Ransomware
Ransomware attacks are the most expensive attacks that happen. According to the research conducted by Sophos, it was found that in 2021, around 66% of organizations were affected by ransomware attacks. It caused a lot of harm to the organizations.
Before we move on to a deep understanding of ransomware, let us understand what ransomware is.
Meaning of Ransomware
It is a kind of malware attack in which cybercriminals lock and encrypt the important data of a victim and then demand money to release the data from encryption. And if a victim is unable to pay them within a certain period of time, the data is gone forever. It is a scary issue that is faced by a number of organizations across the world.
Types of Ransomwares
There are three main types of Ransomwares and those are:
A. Scareware
These are the fake messages that appear randomly on a victim’s computer. A message will show that it has detected malware on a system, and to remove that malware, you need to pay a certain amount, which will for sure remove the malware from devices. If an individual does not take any action, it will continue to show warning alerts. People who already have security software will not have to pay an extra fee for it.
B. Screen Lockers
In this type of ransomware, the victim’s computer is locked, preventing them from accessing their data and information. And they demand money in exchange for leaving your data. A full-size window appears, which shows the following information related to the amount you are bound to pay: However, your screen officially does not get locked until anything illegal is detected.
C. Encrypting Ransomware
Those criminals who have attacked a victim’s computer and stolen information usually demand money, and if a victim does not pay an amount, they must forget about the data. And if they pay, there is also no guarantee whether they will give your data and information back or not. This is also the most dangerous type of ransomware, where all of your data can vanish within a few seconds.
How is Ransomware distributed?
Cybercriminals are very wise, and they adopt different methods to distribute ransomware across devices. Anyone can fall into the trap, and by mistake, a victim can click on a link or visit a webpage that may include malicious codes. And on the other hand, it also happens when one installs a specific file that is harmful. Let us see what other ways of distribution there are:
Ø Phishing Email – Clicking a link in an email can land you on a suspicious webpage.
- Social media – All around the world, billions of people use social media, and cybercriminals take advantage of this. They mention malicious links on social media pages like Twitter, Facebook, or Instagram. Anyone who clicks falls into a trap.
2. Corrupted programs – There are some programs that are corrupted, and unknowingly, some individuals install programs that involve malicious codes.
3. Malvertising – In a day, a number of ads are run by Google. But the ads that contain malicious code are known as Malvertising. It distracts a person from clicking on the link, and when a person does that, it destroys information in a system.
Practices to avoid data breaches
To avoid all kinds of risks, it is better to implement the best practices that can protect an organization from data breaches. Let us discuss what measures an individual can take to prevent a ransomware attack from attacking their information:
· Network defences
It is better for an organization to use a firewall like the Check Point UTM firewall, which includes an intrusion detection system.
· Ransomware detection
Install software that allows you to detect the ransomware quickly. Make use of deception-based detection, which has the capability to quickly analyse the ransomware attacks.
· Whitelisting and blacklisting
Make sure that you have streamlined the settings according to your business needs and have not forgotten to whitelist and blacklist the websites that are safe and unsafe. Also, deactivate macros in word processing.
· Endpoint Protection
An anti-virus that can only protect against a ransomware attack is like a myth, as it is unable to avoid most of the other attacks. So, it is recommended to install various endpoint protections that provide next-generation antivirus which protects against advanced fireless attacks like WannaCry or zero-day malware.
How Check Point firewall prevent Ransomware attacks?
Check Point’s firewall has exceptional features and policies that have the potential to block all kinds of ransomware attacks. Features such as blocking the unknown IP address, filtering URLs in advance, intrusion detection prevention systems that detect unusual traffic, and application control features that prevent an individual from installing an unauthorized application can stop the ransomware attacks from spreading.
This is how the Check Point firewall, with its advanced features, prevents ransomware attacks from happening. Thus, making it necessary for the organizations to install a powerful firewall that can enhance security.
