The Internet is a place full of danger. Hackers, malware, viruses, and other cyber threats lurk around every corner and potential intruder can easily access your computer. A firewall is essentially a safeguard that prevents intruders from accessing your computer or network. However, not everyone thinks they need one.
A firewall is basically a security system, which monitors incoming and outgoing traffic on your computer or network and blocks anything it deems as suspicious or untrusted. Because of this, firewalls are an essential part of any security system because they keep out intruders looking to exploit weaknesses in your network or software in order to steal personal information or delete important files. Let’s take a closer look at why you should have a firewall.
You’re at risk of malware and ransomware
If you’ve ever opened a spam email, then you’ve come dangerously close to a malware infection. Malware is basically any harmful software that can damage your computer or steal your data. What’s even more alarming is that a lot of people don’t even know they have malware on their computer. Some of the most common types of malware include viruses, worms, trojans, and ransomware.
Viruses are an infectious piece of code that can hijack your system and delete files, worms travel through networks looking for ways to spread, trojans are a form of malware that disguises itself as something helpful, and ransomware is malicious software that encrypts your personal files so you can’t access them. Malware isn’t always delivered through emails, either. You can also encounter malware in software downloads, advertisements, and when visiting questionable sites. You can protect yourself from malware by installing a reliable firewall, updating your antivirus software, not downloading suspicious software, and staying away from questionable sites.
You put confidential information at risk
If you don’t already have a firewall, then you’re putting your sensitive information at risk. The Internet is a highly public place, meaning that your private information is only as secure as the protection on your computer. If you don’t have a firewall, then anyone can access your computer and access your personal information, like credit card data, social security numbers, and login information for your online accounts. They can also delete important files, steal your identity, and infect your computer with harmful viruses or malware. You’re especially at risk if you use public WiFi, since it’s easy for intruders to break into unsecured networks and access your computer. Your firewall keeps intruders out, so your sensitive information stays safe. It also blocks intruders from accessing your computer, so they can’t view your private information or steal it.
It protects you from hackers
You probably think of a firewall as a way to keep intruders out, but that’s not the only reason to have one. A firewall can also be used as a tool to monitor intruders, like hackers, who have already broken into your network. Having a firewall installed on your computer, or on an entire network, allows you to watch for suspicious activity. If you notice someone is trying to access your system without permission, then you can quickly block them before any damage is done. A firewall will also log any suspicious activity on your computer, like IP addresses, times, and the types of files accessed, so you have a record in case anything happens. A firewall helps you protect yourself from hackers who are looking to exploit weaknesses in your network or software in order to gain access to your system. A firewall is like having a bouncer at your front door. It logs who comes in and out, and blocks anyone who might be a threat.
It prevents unwanted guests from crashing your party
If you have a firewall, then you can control who enters your computer and who doesn’t. This is especially useful when you’re sharing a computer with other people, like in a work environment or a college dorm. You can create user accounts and install a firewall to control who has access to the different accounts and what they’re allowed to do. Doing so helps prevent unwanted guests from accessing your accounts and deleting important files or installing malicious software. A firewall also keeps out unwanted guests who are searching for ways to break into your computer. Having a firewall installed alerts you when someone tries to log into your account, so you can take immediate action to protect yourself and your computer.
It provides an extra layer of protection for your computer
Your computer is only as secure as the protection you put on it. If you have an antivirus software, firewall, and updated operating system, but don’t have a backup system in place, then you’re putting yourself at risk of losing important files. A lot of people assume that their antivirus software will automatically back up their computer, but that isn’t always the case. Make sure you have an external hard drive or online backup account to protect yourself from losing data in the event of a malware or computer crash. You should also make sure your firewall is configured properly so it can do its job properly. Make sure you have the most up-to-date version of your operating system to protect yourself from computer vulnerabilities, and make sure you have a firewall installed to block intruders from accessing your system without your permission.
A firewall is an essential part of any computer security system because it blocks intruders looking to exploit weaknesses in your network or software in order to steal personal information or delete important files. You’re especially at risk of malware and ransomware if you don’t have a firewall installed on your computer. A firewall helps you protect yourself from hackers who are trying to break into your system, too. It also provides an extra layer of protection for your computer to keep you safe in case of a computer crash. If you don’t already have a firewall installed on your computer, then it’s time to get one.
