Firewall - ZADIG Smart

How it Works!

Block harmful internet traffic
Block suspicious data packets
Remember ongoing conversations and generate alerts
Ensure digital security

When you connect to the internet, your computer is exposed to various traffic, including harmful elements like viruses and hackers. Without precautions, this traffic can reach your machine. Firewalls act as internet security guards, positioned between your computer and the web. They inspect incoming data, allowing safe data and blocking suspicious or dangerous content, similar to a security guard protecting a building's entrance.

A firewall acts as a digital gatekeeper for your computer or network’s security by performing the following functions:

Traffic Monitoring: It watches incoming and outgoing data packets on the internet, similar to a security guard overseeing traffic on a busy road.
Packet Inspection: The firewall inspects each data packet, examining its source, destination, and content.
Rule-Based Filtering: It follows a set of rules that determine which data is allowed and what should be blocked. Trusted sources and legitimate requests are permitted.
Conversation Tracking: Firewalls remember ongoing conversations between your computer and the internet, increasing the likelihood of allowing legitimate data.
Suspicious Activity Blocking: If data packets don’t meet the rules or seem suspicious, the firewall blocks them to prevent harmful content like viruses or hackers from infiltrating.
Alerts and Logging: In uncertain cases, the firewall can generate alerts or logs, allowing you or a network administrator to review and make future traffic decisions.
Outbound Protection: It monitors data leaving your computer to prevent unauthorized information leaks, especially sensitive data.

In summary, a firewall acts as a crucial digital security measure, examining and regulating all data entering and leaving your computer or network to safeguard against potential internet threats. Firewall functionality is completely configured on ZADIG Smart service. You can use it without any additional set-up!

What are the risks?

Browsing the internet without a firewall expose you to a wide variety of risks.

Malware Infections

A malware infection refers to the unauthorized presence and activity of malicious software, commonly known as "malware," on a computer, device, or network. Malware infections can occur through various vectors, such as downloading infected files, clicking on malicious links or email attachments, visiting compromised websites, or exploiting software vulnerabilities . There are some different types of malware like: viruses, worms, trojans, ransomware, spyware.

Hacking Attempts

Hacking attempts involve unauthorized attempts to gain access to computer systems, networks, or data for malicious purposes. These attempts can come from individuals, groups, or even automated scripts and can take various forms. Here are some common types of hacking attempts: Brute Force Attacks, Phishing Attacks, Malware Attacks, SQL Injection, Cross-Site Scripting (XSS), Man-in-the-Middle (MitM) Attacks, Password Cracking, Social Engineering and File Upload Vulnerabilities.

Data Theft

Data theft is the act of stealing digital information stored on computers, servers, or electronic devices to obtain confidential information or compromise privacy. The data stolen can be anything from bank account information, online passwords, passport numbers, driver's license numbers, social security numbers, medical records, online subscriptions, and so on. Once an unauthorized person has access to personal or financial information, they can delete, alter, or prevent access to it without the owner’s permission. The malicious theft of employee data often occurs without the victims ever knowing about it, as a result of their accounts or personal devices being compromised by hackers capitalizing on poor password management or unsecure networks.

Unwanted Traffic

Unwanted traffic refers to any data or network activity that is not desired or intended by the recipient or administrator. Unwanted traffic can encompass a variety of activities and sources, and it can have negative consequences, including network congestion, security risks, and resource consumption. Here are some common examples of unwanted traffic: spam emails, unwanted network scans, distributed denial-of-service (DDoS) attacks and phishing attacks.

Lack of Privacy

Lack of privacy refers to situations where sensitive or confidential information transmitted over a network is at risk of being intercepted, accessed, or disclosed by unauthorized parties. Network security is essential for protecting data privacy. A firewall can filter incoming and outgoing network traffic, preventing unauthorized access and protecting data privacy.
