Understanding Digital Security
Digital security refers to the protection of digital data, systems, networks and devices from unauthorized access, theft, damage or disruption. It encompasses measures to prevent and respond to cyber threats and attacks that could compromise the confidentiality, integrity and availability of digital assets.
The main pillars of robust digital security include:
Access controls and authentication (e.g. strong passwords, multi-factor authentication)
Data encryption to protect information both at rest and in transit
Network security controls (firewalls, VPNs, intrusion detection/prevention)
Malware protection through antivirus/anti-malware software
Regular software updates and patching to fix vulnerabilities
Security awareness training for individuals and staff
Incident response planning for cyber attacks
Some prominent digital security risks in Bangladesh include:
Phishing attacks aimed at stealing login credentials or financial information
Spread of malware like viruses, worms, trojans and ransomware
Hacking attempts to breach systems and data
Identity theft and online fraud
Denial of service (DoS) attacks on websites/networks
Social engineering tactics to manipulate people
For individuals
Financial losses from identity/data theft or fraud
Privacy violations and personal data exposure
Emotional distress and reputation damage
For organizations
Business disruption and loss of productivity
Financial losses, fines and legal issues
Theft of proprietary data or intellectual property
Damage to brand reputation and consumer trust
Maintaining digital security is crucial to protect against these detrimental impacts in Bangladesh's growing digital landscape.
Current State of Digital Security in Bangladesh
Bangladesh has taken some initial steps to build a digital security infrastructure, however, there are still significant gaps and room for improvement:
The government has established a Computer Incident Response Team (CIRT) under the Bangladesh Computer Council to monitor and respond to cyber threats.
The Bangladesh Telecommunication Regulatory Commission (BTRC) has guidelines for cybersecurity frameworks for telecom operators.
Financial institutions are required to maintain certain security standards set by Bangladesh Bank.
There are a few private computer emergency response teams (CERTs) and cybersecurity firms in operation.
However, Bangladesh lacks an overarching national cybersecurity strategy and legal/regulatory framework.
Despite the emerging infrastructure, individuals and organizations in Bangladesh face several digital security challenges:
Low cybersecurity awareness and lack of training among general public
Inadequate technical capabilities of many organizations to implement robust security
Widespread use of pirated/unlicensed software which isn't updated regularly
Lack of local security tools, technologies and skill development opportunities
Insufficient budget/investment allocated towards cybersecurity by many entities
Absence of data protection laws and security breach notification requirements
The government has recognized the need for enhanced digital security and taken some policy measures:
Bangladesh's 8th Five Year Plan (2020-2025) prioritizes cybersecurity capacity building
The National Cyber Security Strategy (NCSS) 2021-2023 was introduced, but lacks implementation
Plans announced to enact laws on cybersecurity, cybercrimes and data protection
Allocated budget to establish a Cyberthreat Detection and Mitigation Center
Public awareness campaigns conducted on safe internet practices
However, most initiatives are still in nascent stages with slow progress
While initial steps are positive, Bangladesh has much work ahead to develop a robust, coordinated and comprehensive national cybersecurity posture.
Best Practices for Individuals
Using strong, unique passwords for all accounts is crucial to protect your digital identity and data. Follow these password best practices:
Use long passwords of 12+ characters with a mix of letters, numbers and symbols
Avoid common words, phrases or personal information in passwords
Use a different password for each account/website
Consider using a password manager tool to securely generate and store passwords.
Phishing emails/texts and social engineering scams try to trick you into revealing sensitive information or installing malware. Stay vigilant:
Verify the source of any communication requesting personal/financial details
Don't click suspicious links or attachments from untrusted sources
Check for misspellings, strange phrasing or suspicious sender details
Never provide credentials or sensitive data in response to unsolicited requests.
Exercise caution while browsing online to reduce risk exposure:
Avoid visiting untrusted/suspicious websites which could be malicious
Use secure "https" connections when possible for safer web browsing
Don't enter sensitive information on unsecured public WiFi networks
Clear browser cache/history regularly and use incognito/private mode
Disable browser option to automatically log into sites.
Encryption scrambles data to prevent unauthorized access:
Use encryption tools like file/disk encryption or encrypted messaging apps
VPNs (virtual private networks) encrypt your internet connection for added security.
Software updates often include critical security fixes:
Keep all software (OS, apps, browsers etc.) updated to the latest version
Enable automatic updates, or regularly update manually
Use authentic software from trusted/verified sources only
Implementing these digital hygiene practices can greatly enhance your personal cybersecurity posture.
Best Practices for Organizations
Organizations should have comprehensive, well-documented cybersecurity policies covering areas like:
Acceptable use of IT systems and data
Access controls and authentication requirements
Data security and encryption standards
Incident response protocols
Regular policy reviews and updates
Enforcing these policies through technical controls and employee training is crucial.
Since human error is a major cyber risk factor, ongoing security awareness training for all employees is vital:
Educate on cyber threats like phishing, social engineering, malware etc.
Teach best practices for passwords, internet use, data handling etc.
Run simulated phishing tests to identify gaps
Keep employees updated on latest cyber risks and protection measures
Protecting organizational networks and systems is paramount
Implement firewalls, intrusion detection/prevention systems
Use secure VPNs for remote connectivity
Apply the principle of least privilege for access controls
Regularly update/patch software and systems
Deploy antivirus/anti-malware defenses
Perform penetration testing and vulnerability assessments
Safeguarding sensitive data is critical for organizations:
Encrypt databases, documents and communications containing sensitive data
Maintain secure, encrypted backups in case of data loss/breach
Implement access controls on sensitive data stores
Have secure processes for data disposal/deletion
Have strategies in place to swiftly detect, respond to and recover from cyber incidents:
Develop detailed incident response and disaster recovery plans
Assemble dedicated cybersecurity incident response teams
Conduct periodic testing/simulations of the incident response plans
Have systems in place for timely security patches and fixes
Securely store backup data that can be used for restoring systems
Implementing a multi-layered, holistic cybersecurity approach based on best practices can help organizations preempt and mitigate cyber risks effectively.
Emerging Technologies and Trends
