Twelve Varieties of Digital Protection Strategies
In today's digital age, cybersecurity has become a paramount concern for businesses across the globe. The European Union (EU) has taken significant steps to strengthen cybersecurity, with the institution that developed the NIS2 cybersecurity guideline being the EU itself.
One of the key aspects of a robust cybersecurity strategy is saving all visits and maintaining a record of all activities. This is coupled with limiting worker access with a badge system and creating multiple security zones. Each user is only allowed to access the information they need to perform their missions, ensuring that sensitive data remains secure.
To further enhance security, an Intrusion Detection / Prevention System (IDS/IPS) is employed to monitor all communications. This system helps in detecting and blocking potential threats, providing an additional layer of protection.
External media players such as USB sticks are checked for viruses before they are connected to a computer. All connections to the corporate network are secure and encrypted, ensuring that data remains confidential during transmission.
The use of Virtual Private Network (VPN) connections from endpoints is restricted, and sensitive or confidential data is transmitted only in encrypted form. Secure applications and protocols are used to further bolster security.
Physical access to servers and network components is logged, and unused accounts are disabled immediately. Security logs on servers and firewalls are kept for a period of at least 1 month, providing valuable insights for incident analysis and response.
An alert-based analysis and alerting system for detecting malicious behavior (SIEM) is also implemented. This system helps in identifying and responding to potential threats promptly.
To respond effectively to incidents, businesses should have an incident management plan in place. This plan outlines the steps to be taken in the event of a security breach, ensuring a swift and effective response.
In addition, a business continuity plan is essential to preserve the business in the event of a major incident. This plan outlines the steps to be taken to ensure business operations can continue, even in the face of a security breach.
To further protect the business, all workers must know the point of contact to report an incident. This ensures that incidents are reported promptly, allowing for a quick response.
Physical security of the computing environment is also crucial for system protection. All computers connected to a server form a network in the workplace, and laptops, smartphones, and tablets are never left unattended. Workstations and unused mobile devices are locked automatically.
Enterprise Wi-Fi is protected with WPA2 encryption, and unused ports and services are closed. The public Wi-Fi network is separate from the corporate network.
To reduce the number of security breaches, continuous training of employees and the implementation of security technologies are crucial. Strong authentication is used when connecting from outside public networks, and passwords must be at least 10 characters long and a combination of character types.
Default passwords should be changed, and the "Autorun" function of external media is disabled. Passwords must be changed periodically or whenever there is a suspicion of compromise.
A reliable backup and recovery solution is the second and most important layer that gives businesses the ability to reboot quickly in the event of a major incident. This solution ensures that data can be restored quickly, minimizing downtime and reducing the impact of a security breach.
In conclusion, developing a strong, multi-layered security strategy using each of the 12 types of cybersecurity can save a business. This strategy, coupled with continuous training of employees and the implementation of security technologies, provides the first line of defense and significantly reduces the number of security breaches.
