What is a firewall?
A firewall is equipment or software that is placed between a trusted internal network and an untrusted external network, such as the Internet. Its purpose is to protect the internal network from attacks originating from the external network. Firewalls can be either hardware- or software-based, and they are often used in conjunction with each other.
A hardware firewall is a physical device that is placed between the trusted and untrusted networks. Hardware firewalls are typically used to protect larger networks, such as corporate networks or networks that provide Internet access to multiple users. Common hardware firewall features include the ability to control traffic based on specific criteria, such as the source or destination of the traffic, and the ability to block specific types of traffic, such as Internet Protocol (IP) address or port number.
A software firewall is a program that is installed on a computer that is connected to the untrusted network. Software firewalls are typically used to protect individual computers, such as those used by home users or small businesses. Common software firewall features include the ability to control traffic based on specific criteria and the ability to block specific types of traffic.
Firewalls can be used to protect both computers and networks from attack. However, they are not a perfect solution, and they should not be the only defense against attack. Firewalls can be bypassed, and they can be configured incorrectly. In addition, some attacks, such as those that exploit vulnerabilities in application software, can pass through firewalls without being detected. Therefore, it is important to use other security measures, such as antivirus software and intrusion detection systems, in conjunction with firewalls.View it
What is phishing?
Phishing is a type of online fraud in which criminals pose as a reputable organization and attempt to trick people into providing personal or financial information. Phishing scams can take many different forms, but they all typically involve some form of email or website that looks legitimate but is actually a fake.
One of the most common types of phishing scams is what’s known as a “spoofed” email. This is where a criminal will send an email that appears to be from a legitimate organization, but is actually a fake. The email will usually include a link that takes the recipient to a fake website that looks identical to the real thing. The goal is to trick the person into entering personal or financial information, which the criminal can then use for their own purposes.
Phishing can also happen through instant messages, text messages, and even phone calls. In each case, the goal is the same: to trick someone into giving up personal or financial information.
Phishing is a serious problem because it is becoming increasingly difficult to tell the difference between a legitimate email, website, or message and a fake one. Criminals are getting better at creating fake versions of real websites, and many people have fallen victim to these scams.
If you receive an email, message, or phone call that you think might be a phishing scam, the best thing to do is to simply delete it. Do not click on any links, and do not reply to the message. If you believe you may have already given your information to a phishing scam, you should contact your bank or credit card company immediately to report the fraud.
