But the encryption of the website may not necessarily reveal if any malware is stored in it. Medical professionals also send encrypted information while sharing confidential information of patients. Encryption is basically re-writing the information in the form of a code which only one device can understand. The websites usually encrypt your personal information like name, passwords so that the hackers cannot access your data. The importance of encryption is profound. The firewall system first has to decrypt it and this is the tougher task. One of the challenges for companies is to do the ‘deep packet’ checking of the data that comes into the network which is encrypted. That is they do not check the data inside it, unlike some of the modern, more advanced security systems. Another common thing which market products do is that they just check the heading information of the packets. That is what leaves most of the security and data vulnerable.
If they do not and if the first step is clear, they are allowed to pass through the firewall.īut a common flaw in the market is that the firewall only fulfils the first part. The next step includes the firewall inspecting the data to see if they contain any malware or virus.The NAT device in the software first verifies if the IP address is allowed to enter or exit the data from your device.There are a couple of things that primarily happen when it interacts with the firewall. When the information passes through the network in the form of packets, they have to cross the firewall.
In layman terms, a firewall is the first defence barrier laid out by your network. However this is not true as many cybercriminals actually see small businesses to be easy targets due to their lack of security. A common misconception many small businesses have is that they are safe from a cyber-attack because it is only big corporations who are targeted by cybercriminals, so they don’t invest in firewall and virus protection. Many businesses are slowly realizing that this could be the reason why their content and data is not as safe as it should be. People who have experience with using a computer can easily fathom the importance of antivirus software, but not many people would also know why a firewall is important, or what it even is.
