The recent identification of serious security vulnerabilities in the PHP programming language has prompted institutions in various countries around the world to take precautionary measures.
This also carries an important message for Bangladesh. The country’s security no longer depends solely on its borders or military strength; the security of databases, financial systems, and digital services is equally important. Even minor negligence in this area can lead to major disasters.
It is known that PHP, a widely used programming language for website development, is employed by countless news outlets, commercial organizations, and online services around the world.
Following the recent discovery of two serious security vulnerabilities in the language, experts have expressed concern that attackers could exploit these weaknesses to execute unauthorized commands on servers remotely, without needing a password.
This could put files, databases, and important documents stored on those servers at risk. However, the use of PHP does not automatically mean that a website will be compromised.
The level of risk depends on the version in use, the installation of security updates, and the overall security measures in place.
According to available information, approximately 36,500 websites under Bangladesh’s National Web Portal are not built using PHP and therefore are not expected to be directly exposed to the current vulnerabilities.
However, this is no reason for complacency. PHP may also be used in various online services outside the National Web Portal, and the actual level of risk cannot be determined without examining the security of all these systems.
In such a situation, should we not look back at Bangladesh’s past experiences? The Bangladesh Bank reserve heist in 2016 demonstrated how vulnerabilities in digital security can cause enormous financial losses.
If an institution connected to the international financial system has flaws in its security arrangements, the consequences can naturally affect the country’s reputation and financial stability as well.
The temporary shutdown of the Bangladesh Bank website in recent times as a precautionary measure over security concerns has also brought these worries to the forefront.
Of course, shutting down a website may be a necessary precaution under certain circumstances. Keeping it closed for days on end, however, is by no means desirable.
What is needed is to identify vulnerabilities, eliminate them, and build the capacity to prevent future attacks.
This is the approach adopted by developed countries. There, cybersecurity is not regarded solely as the responsibility of the information technology department.
Along with issuing timely warnings about various vulnerabilities in cyber systems and infrastructure, they regularly advise organizations operating vulnerable digital systems to conduct security audits, update software, back up data, and maintain effective intrusion detection systems.
Moreover, particular importance is given to taking effective measures to prevent potential cyberattacks on critical digital infrastructure. These include risk assessments, clearly defined responsibilities, emergency response drills, the recruitment of skilled personnel, and continuous monitoring.
The central lesson of all these initiatives is that taking preventive measures in advance, rather than waiting for a disaster to occur, is the wiser course of action. Should we not follow the same path?
A website can be compared to a valuable piece of land. Just as land requires care, irrigation, and protective fencing to produce a good harvest, digital assets also require regular maintenance and a strong protective framework.
We must remember that the cost of negligence in cybersecurity cannot be measured in monetary terms alone. Cyberattacks can jeopardize citizens’ personal information, an institution’s credibility, and the state’s important documents.
Therefore, competent personnel must be appointed to positions of responsibility, accountability must be ensured, and advance warning must become an integral part of institutional culture.
To avoid a situation akin to handing the keys to one’s own house to a stranger, we must take appropriate preparatory and precautionary measures before a disaster occurs, not after it has struck.
