With the advancement of technology we are becoming exclusively dependent on automation and we can see its influence in all spheres of our life. This journey of Internet first started 1960 with the creation of ARPHANET Then it became popular in 1990 when web was used as the medium Following the modern world, Bangladesh was first introduced to internet in 1996. In 2006 Bangladesh got connected with Submarine Cable (SEA-ME-WE 4 Submarine Cable) which afforded targe bandwidth and low cost than ever before.Now we are in 2021. Internet has reached in the distant corner of the country. According to BTRC, number of total internet subscriber is 91.42 million or 9 crore 14 lakh. (Internet Subscriber means subscribers/subscriptions who have accessed to the internet at least once in the preceding 90 days). We can sense the sharp growth of this industry if we know this amount was 8 crore and 10 lakh in 2018 Within a year it has been increased by 1 crore in this sector social networking sites are playing a vital role Int January 2019, total active facebook-users are 3.37.13,000 which is near to 90% of the total the 3 and w But r ed social site users in the country. Beside Facebook, people are using WhatsApp. Viber, Imo, Snapchat, Instagram etc nowadays. People are making new friends, making group of common ground, helping each other, smiling together in national achievement or positive incidents. protesting together against negativity These all are good signs. These are signs of hope and pride. When internet was developed, the founding fathers of internet hardly had any idea that Internet could also be misused for criminal activities. But the fact is that it is happening roughly and largely all over the world Conventional crimes are prima facie territorial and occur in physical world, but cyber-crime is territorially unlimited and in the world which is an electronic or virtual one. These crimes are being committed frequently now-a-days. With the increase of internet user in Bangladesh, crimes are also increasing. We can have a look on the number of cases filed in recent few years. According to Cyber-Crime Department of Bangladesh Police. It was 597, 879. 1028 and 1765 respectively in 2015, 2016, 2017 and2018. These crimes are committed in different forms like cyberstalking, cyberbullying, hacking. fake social media profile, photo manipulation, using one's personal photo or information for blackmailing, insulting comments, mailing threats, sending obscene message or distributing pornographic photos or videos. Nobody is safe in this virtual world. We often see hackers take access to the system and steal or change sensitive information. They are successful because of the unawareness of general people. Actually Bangladesh is going through a transition period. Automated systems are being introduced. People have started using online medium but they are not expert and they don't have much knowledge about the security & privacy issues. There are some security policies that must be followed when we are on virtual world:
1. Don't share your password. Always use the combination of uppercase, lowercase and special sign (<..#.!) as your password. Try to ignore the words like your name, birth year, pet name or the words that exist in the dictionary. Don't use the same password for different social sites or mail address.
2. You have to be very choosy when you are going to believe an unknown person on this virtual world. Don't get access to your mail or other social site account from other's device. Think twice before you are posting a photo, adding a person as your friend.
3. Try to avoid advertisement site. Don't register in this type of sites using your e-mail or password because this sites can be a trap for you. Don't click on the unimportant links that is sent to you by unknown people.
4. Don't share your credit card and other sensitive information on the internet specially in online shopping sites. Because if that website is hacked by hackers, your sensitive information will be in their database. The above-mentioned steps were to keep yourself safe. You must follow some other ethica rules to keep the whole virtual world safe:
1. Don't spread rumors consciously o unconsciously. Justify the news or information before you share it .
2. Don't spread negativity intentionally. This cre breaks down social bonding.
3. Don't make comments to humiliate someone.
4. Install a firewall.
5. Don't try to threaten people using virtual medium. Because you can be traced even if you use VPN.
6.Don't create fake profiles cr edited/manipulated photo that create social instability.
7. Think before you share your location in public Because someone may be keeping eyes on doing harm to you.
Analyzing the incidents happening around us,we can say that, the most important security measure is increasing awareness among all.We have to be more ethical when we are surfing on the internet. Hope we will stay safe in our second world. We just have to remember that "A chinis as strong as it's weakest point".So, we should be concerned about every single privacy issue on the Net.
Welcome; I see this your first post here. You bring up a very important subject: privacy on the Internet. I suggest, however, that you try to divide the long first paragraph into several. It is a too massive piece of text as it is; without doubt, a lot of people will just skip reading it.
