The difference between firewall and antivirus is often not understood by many people. This analysis helps you understand the function of both the security infrastructure and the security system you need!
Firewall and antivirus, as many people know, are mechanisms that provide security infrastructure. To make the best use of one or the other, you must consider the distinct limitations of both systems.
A firewall serves as a barrier between the world wide web and your network. It works in the background as a process in your OS and monitors the system’s incoming and outgoing traffic.
It avoids the entry / leaving of ambiguous packets into the network. It does not, however, protect your system or files from viruses, spyware and adware. It can be implemented as a hardware or software. New WiFi routers come with a built-in firewall to protect your network from the rest of the network.
Firewalls are categorized into four types:
Packet Filtering Firewall: It eliminates unwanted network communications and only allows validated access. It is usually deployed on routers.
Application Level Firewall: It uses a series of designed policies to decide if communication to or from the receiver should be blocked or enabled.
Circuit Level Firewall: It is deployed to monitor the connection sessions; it tracks a three-way TCP handshake to verify whether or not a requested communication is valid.
Stateful Multilayer Inspection Firewall: It is a combination of all the other three types of firewalls. It basically implements algorithms and sophisticated security systems, which are design and protocol specific to make the connections and data transfer secure.
Antivirus software is a detective and preventive tool, commonly used in most private PCs and workplaces. The software finds and neutralizes your computer’s malicious content.
The primary function of it is to search, identify, and prevent any uncertain or mistrustful files and data to enter the system. It runs in the background and uses a range of security measures like quarantine, repair, or permanent removal to protect the system when a virus is detected.
Crucial Difference Between Firewall And Antivirus
It can be installed both on hardware and software. To enable it on your computer or devices, check the operating system’s firewall availability or install an antivirus which comes with firewall feature.
It can only be installed on compatible operating systems. You can enable it on a computer, smartphone, or tablet by installing the best antivirus with high-end features on your device, launch & activate the application, and you are protected.
#2. Security Approach
It is deployed as a shield and becomes activated when you go online. The security of the firewall keeps your device and personal information secure from invasion and malicious threats.
It’s clear that a firewall protects your device from hackers ‘ interference and prying eyes while the antivirus removes detected malicious content and viruses from your computer.
Antivirus uses defined or known patterns to search, identify, and prevent malicious content and viruses from entering your computer.
These patterns are usually upgraded by software providers in the latest updates to improve the efficiency of the software.
#3. Prevention And Protection Approach
A firewall acts as a preventive measure; it monitors and prevents malicious content or viruses from entering into your network.
Nevertheless, via spam links, e-mail attachments, USB or other storage devices, viruses can still enter on your computer.
It is an appropriate protection measure against all the spam links, e-mail attachments, USB, or other storage devices containing malicious content or viruses.
Whenever a virus-infected file or malicious content is detected on a computer, the antivirus tries to eliminate the infected file, delete it or notify the user of its presence to take further action.
#4. Which Security System You Need?
To stay secure, you need both the security systems. The firewall helps prevent network attacks on your devices, and if accessed via any channel on your computer or devices, an antivirus can remove the infected files.
You can keep your network protected by installing a firewall on any border network region with different levels of security to filter out malicious data packets that could compromise your network and file security.
You can keep almost any tech device secured; an antivirus must be installed on all computers, smartphones, and tablets to keep the files safe from malicious content or viruses.
After reviewing the complete analysis of the difference between firewall and antivirus, it is suggested that both the security system should be installed and activated to keep files on your devices secure.
Further, a firewall protects the device from unauthorized access by tracking and filtering incoming and outgoing information data packets. An antivirus is a software tool designed to restrict the entry of viruses or harmful files into the system, keeping your device safe at all times.
It is highly recommended to have an antivirus installed on your computer or other tech devices, not just a free version; as such, it only restricts limited harmful files or viruses and lacks proper repair, removal ability of the infected files.
