Cyber ​​Security Specialist Okan Algün is a professional who gives training on security in various institutions. Our paths met recently and ways to browse the internet safely we asked.

Ways to surf the Internet safely

Developing with an unstoppable speed, technology brings the same speed to us by constantly updating the weaknesses in this field.

Internet is everywhere now

The virtual world, where we are online in seconds through many devices and interact with billions of people, has become a danger as well as providing benefits for individuals. As a result of this danger, when we talk about the virtual world, one of the first issues that comes to our mind is security.

I can say that security in the virtual and real world is similar in many respects. I try to explain this subject with various examples in my columns or seminars. One of these examples is that the key to our house is equivalent to the passwords we use on the Internet.

Just as we should not give our house keys to people we do not know, we should not share our passwords with people we do not know, or we should not hide our house keys under a mat that anyone can easily guess, and we should not create passwords that cannot be guessed by everyone.

When we leave our house or workplace, we do not leave our street door wide open. I don’t think anyone will have the thought that “I hope no thief will notice that my door is open”. Remember that valuable materials in our home are equivalent to your data on the internet.

For this reason, we must take the maximum security measures we can within the technological devices we use, similar to the measures we take in our real-life living spaces. Remember that your first line of defense against malicious people is your passwords and security settings.

What can we do to protect internet security?

• Do not download programs or files from sites of unknown origin
• Pay attention to the extension of the site you are searching for from the search engines, and if the site you want to take action is a government agency, make sure that the extension is “gov.tr”. Search and learn about other web extensions on the internet.
• There may be e-mails prepared by social engineers with titles that may arouse your curiosity, do not click on the links in e-mails you do not know.
• Make regular updates of our operating systems
• Change your passwords at certain intervals and do not use the same password in several systems, do not write your passwords on your phone, computer, note papers, prepare passwords created with computer special characters that you can remember.
• Prefer licensed antivirus programs
• Be careful not to log into systems that are important to you, such as banking, from free wifi networks or in areas with guest internet providers.
• If you need to be included in a network with your personal computer, make sure your settings such as the firewall in your operating system are turned on, carefully examine the firewall settings of your modems.
• Prefer sites that require a password on websites and have HTTPS features for your payment transactions.

Internet security is an important area that needs attention in every aspect, whether individually or commercially. Leaving systemic openings by not paying enough attention will cause you to suffer serious financial and moral losses.

The user-level security measures I described in my article will be enough to protect you from the attacks of young people at the Script Kiddie, Lamer Level. If you have company data or valuable material that you think is worthy of a real Black-Hat attack, I recommend that you seek professional support in this regard.

In the first attack that will happen to you afterwards, you may encounter conversations such as “your password was very easy”, “the programs you downloaded to your computer definitely had viruses”, “you did not make the necessary security settings”, “if you had asked someone who knows”. Against these conversations, you rightly say, “Hacker’s not guilty at all?” don’t have to say
