Physical security can be an important aspect of cybersecurity in the current world of ever growing convergence between both because it helps protect against physical threats that could compromise the confidentiality, integrity, and availability of sensitive information and systems. A strong physical security strategy can provide an additional layer of protection against cyber attacks and other security breaches.
Physical Access Control
One way that physical security can strengthen cybersecurity is by restricting access to corporate facilities and data centers. This can help prevent unauthorized access to devices or systems that contain sensitive data, which can be a major risk factor for cyber attacks. For example, if an attacker gains physical access to a computer or server, they may be able to install malware or steal data. Therefore, it is important to implement physical security measures, such as locks, security badges, and security guards, to prevent unauthorized access to faciblities and data centers.
In Nigeria, physical security measures have played a role in helping to prevent data breaches. In 2019, the Central Bank of Nigeria (CBN) implemented a number of physical security measures at its data centers, including biometric access control systems, surveillance cameras, and security guards. These measures have helped to prevent unauthorized access to the data centers and protect against data breaches.
Environmental Controls:
Another way that physical security can strengthen cybersecurity is through the use of environmental controls. Data centers and other critical infrastructure are vulnerable to environmental threats, such as fires, floods, excess moisture and extreme temperatures, which can damage hardware and data. Therefore, it is important to implement measures to protect against these threats, such as fire suppression systems, flood barriers, and temperature control systems. According to a report by the National Institute of Standards and Technology (NIST), environmental threats were the leading cause of data center outages in 2018, accounting for 41% of all outages. By implementing effective environmental controls, organizations can help prevent damage to hardware and data, and reduce the risk of disruptions to critical services.
Physical Security Training:
Physical security training can also play a role in strengthening cybersecurity. Employees who are aware of physical security risks and best practices are better equipped to identify and report potential threats. This can include things like spotting suspicious activity around corporate facilities or data centers, properly disposing of old or decommissioned equipment, and following secure data handling procedures. A study by the SANS Institute found that employee training was one of the most effective ways to prevent data breaches, with organizations that provided regular training experiencing fewer breaches than those that did not.
In Nigeria, employee training has been identified as an area of focus for improving cybersecurity. According to a report by the Nigerian Communications Commission (NCC), most data breaches in the country are caused by employee negligence or lack of awareness. To address this issue, the NCC has recommended that organizations implement employee training programs to raise awareness of cybersecurity risks and best practices.
Secure Disposal:
Secure disposal of equipment is another important aspect of physical security. When old or decommissioned computers, servers, and other equipment are not properly disposed of, they may be accessed by unauthorized individuals who could potentially extract sensitive data. This is why it is important to implement secure disposal practices, such as wiping data from devices before they are disposed of, or using a secure data destruction service.
Secure Disposal of equipment has been identified as a key area for improving cybersecurity. A report by the Nigeria Cyber Security and Infrastructure Protection Agency (NCSIPA) found that many organizations in the country do not have proper disposal policies in place, which puts sensitive data at risk. To address this issue, the NCSIPA has recommended that organizations implement secure disposal practices to ensure that old or decommissioned equipment is properly wiped of data before it is disposed of.
Video Surveillance
Surveillance is another physical security measure that can strengthen cybersecurity. Implementing surveillance cameras and other monitoring systems can help detect and prevent physical security threats, such as theft or vandalism. These systems can also provide a record of activity in and around corporate facilities, which can be useful for investigating security breaches or other incidents. Modern surveillance solutions are now very intelligent being equiped with AI Analytics for detecting threats such as fire, intruder, object disappearance, amd threats classification in real time
In Nigeria, surveillance has played a role in improving cybersecurity at some organizations. For example, the Lagos State Office of Transformation, Creativity, and Innovation (LOTCI) has implemented a surveillance system to monitor and protect its data center. The system includes cameras and other monitoring technologies that help to detect and prevent physical security threats.
Overall, it is clear that physical security can play a vital role in strengthening cybersecurity in a corporation. By implementing measures such as restricted access, environmental controls, physical security training, secure disposal of equipment, and surveillance, organizations can help protect against physical threats that could compromise the confidentiality, integrity, and availability of sensitive information and systems. In Nigeria, these measures have been shown to be effective in improving cybersecurity at some organizations, as it has been identified as part of international best practices.
In conclusion, physical security is an important aspect of cybersecurity that should not be overlooked. By implementing effective physical security measures, organizations can strengthen their overall cybersecurity posture and reduce the risk of data breaches and other security incidents.
