Speakers at a programme on Saturday underscored the need for countrywide awareness programme to make people alert about cyber security.
They also said many people in the country are getting involved in cyber crime as they are somewhat oblivious about existing laws related to cyber crimes prevention.
The observations came at a workshop on 'Cyber Security for Personal and Professional Safety' organised by the women in leadership (WIL) committee of Institute of Chartered Accountants of Bangladesh (ICAB) at its auditorium in the city's Karwan Bazar.
The programme was also supported by Take Back The Tech and Bangladesh Open Source Network (BdOSN).
Presided over by ICAB president Dewan Nurul Islam, the programme was addressed by WIL committee chairperson Parveen Mahmud, Janata Bank chairperson Luna Shamsuddoha, Dhaka Metropolitan Police (DMP) assistant commissioner Syed Nasirullah, BdOSN general secretary Munir Hasan and Right Time Ltd managing director & CEO Md Tohidur Rahman Bhuiyan.
Speaking at the programme, Luna Shamsuddoha said everybody including women should follow the internet security layers in their computers, laptops, tabs and mobile phones.
Emphasising on locking internet devices in workplace with security code, she said auditors should have secure computer networks in their offices so that unwanted person could not intrude in and hack valuable data.
She also mentioned that now-a-days organisations think about the security of their data before awarding audit works to a CA Firm.
Office data should be protected and archived to avoid cyber threat and loss of data, the Janata Bank chairperson added.
She also urged women to keep secure national ID and not to share their password to anyone.
Referring to recent student protest for road safety in the country, Mr Bhuiyan said, "We should be very careful and responsible about what we share, like or post regarding such events."
He said a nationwide awareness programme is required to inform people about know-how of existing laws on internet use.
Many of the social media users don't know what they are sharing, whether their activities are unlawful or not, Right Time Ltd CEO added.
Responding to a question about personal data privacy, he said it is a citizen's right to protect his/her personal data, but on the other hand, government agencies also have the jurisdiction to seek any kind of information from a citizen when needed.
Speaking at the programme, Mr Nasirullah said mass awareness programme is required to make people conscious about cyber crimes, related laws to prevent it and punishment for such acts.
The person who discloses unauthentic data in the cyberspace will have to take liability for it, he said adding media workers, researchers or social media users should mention proper source if they publish something confidential.
Terming most of the cyber criminals highly educated, he said in Bangladesh they committed the crime without knowing the existing law, an ominous sign for the society.
Stressing the need for mass awareness to prevent cyber crimes, the DMP official working in Cyber Security & Crime Division said every citizen have the responsibility to know the law of the country.
Presenting the keynote paper titled 'Cyber Security in Daily Life', Mr Hasan said every minute about 18 million people send text messages, 187 million send emails and a million uses Facebook around the world.
He mentioned that without knowing the objectivity of a news, 78 per cent users share and press on like button on a post in the social media.
He also said organisations should use safe email ID for their data security.
Department of Robotics and Mechatronics Engineering of Dhaka University chairperson Dr Lafifa Jamal and Robi-Axiata general manager (market strategy & planning) Kaniz Fatema also spoke as panel discussants with the moderation of ICAB member Khondkar Atique-e-Rabbani.
