Don’t Look Now, But You Have Been Hacked!

Most national and commercial offices now have firewalls that separate the internal computer network from the wild outside the Internet. The good news is that firewalls are becoming more complex and configured correctly, which protects your internal network computing devices. Modern firewalls now include intrusion detection and prevention, spam filtering, website blocking, and most can report who did what and when. Not only can they block malicious users outside the network, but they can also control users who log in from within, so they can’t access inappropriate resources on the Internet. You can prevent employees from accessing sites that may lose valuable productivity time or violate security compliance requirements by getting certified ethical hacker courses. The first hour of the office is really not the time to update your Facebook page! We don’t want our medical and financial services staff to use instant messaging to talk to people outside!

Firewalls are the electronic equivalent of the “gateway” of computer networks, and there are endless parade of evil potentials. They paint for your doors and windows and constantly look for ways to enter. A firewall that is properly configured, managed, and updated. It protects your computer network very effectively, whether in the office or at home. Behind the firewall, desktop and desktop servers must have locally installed software firewalls that also protect against viruses. Hopefully if there is anything beyond the firewall, the internal firewall and desktop firewall solution will provide an additional layer of security through certified ethical hacker courses.

The firewall is reasonable and appropriate, but this is bad news. Most of the hackers you listen to and read now are not created by criminals who enter the firewall! Actual damage is caused by people on your network! Malicious users and dishonest employees will always be a pleasure. There is always an unscrupulous employee’s taste to pass credit card information or transfer safety information. However, the real danger comes from users who ignore today’s highly complex security vulnerabilities can be acquired by certified ethical hacker courses. The most honest employees may inadvertently become a source of major security breaches, resulting in the loss of their own personal data or personal and financial data of the customer.

Let’s take an ordinary laptop as an example. How many times have you been to Starbucks and installed this store? Good day, open air, sunny and high speed internet connection, cordless phone and its business as always. If I tell you how easy it is to organize a Starbucks man-in-the-middle attack, you will leave the cafe for the rest of your life. You think you are Starbucks WiFi, but in fact, the person behind Starbucks connects the wireless access point to your USB interface and makes you think this is the door to your Internet. Since he logged in, he has been watching every keystroke on his computer. In fact, he now has your username, password, and everything else on your computer. Now when you get back to the office and log in, you just posted a robot on the company network that will come back later tonight!

If the laptop is not enough, everyone is now walking with a smartphone! Do you know? Does your smartphone list all the WiFi networks you have used recently? Remember when you checked your email while Starbucks waited for this cup of coffee? Now, no matter where you go, your phone will send a tag request that looks like “Do you have Starbucks WiFi?” Waiting for you to receive an answer and automatically connect to the Internet. Do you remember the child we talked about? He decided to answer his tag request, “Yes, I am here, keep going!” Just another attack on “MITM” and what you can do with your smartphone, especially using Androids to make your laptop look Like Fort Knocks!

Sometimes, for entertainment and entertainment, when I sit at the entrance to the airport waiting room, I scan WiFi to identify the number of connected, connected phones, computers and iPads. I am not saying that I am willing, but I think you can launch a Netbios attack in less than five minutes? Surprisingly, how many people left their printers on the web and shared options on the go. More people keep their My Network Places settings in their default settings! The simulation is always the same: mapping the network to see the connected hosts; port analysis of known vulnerabilities; removing the exploit kit, and the rest becoming relatively boring for ethical hackers. Now, credit card thief on the other hand…

Your internet browser may be the biggest enemy of privacy protection. Every website you visit, every email you send, and every subsequent link will follow hundreds of companies. do not trust me? If you are using Firefox, install an extension called DoNotTrackme and research what happened. Assuming you are an ordinary Internet user, you will get a list of more than 100 companies in less than 72 hours, and these companies have tracked every action you take on the Internet. These companies do not work for the National Security Agency, but sell their “digital files” to those who are willing to pay for this information. Where is your GPS? Which websites have you visited, which movies have you seen, which products you have purchased, which search terms you have chosen, all of which were officially reported by you and your staff, without any doubt? Have you ever wondered if your competitor wants to know your vision online?
