With the increasing complexity of cyber threats and data breaches, businesses must implement robust measures to protect their networks. That is why a network security policy must be in place to create security guidelines for devices that transport and store company data.
An introduction to network security.
Every company's network is made up of devices that transmit and store information. This can include internal and external systems, whether company-owned or leased.
To protect company data and reputation, it is essential to ensure that the network is protected from unauthorized access, data loss, malware infestations, and security breaches. This must be done through systematic end-to-end controls.
Key Components of an Effective Network Security Policy
With a comprehensive network security policy, an organization can protect its data, reduce the risk of cyber threats, and maintain the trust of its customers and stakeholders.
A company's network security policy should include robust network security measures, such as guidelines on configuration, physical security, operating system security, application security, and procedural security.
For example, a policy should clearly state that workstations, laptops, servers, switches, routers, firewalls, mobile devices, and wireless access points must have access and security logs enabled, and that these logs must be protected from tampering or erased, whether deliberately. or accidental. Whenever possible, it is recommended to keep these logs in a central location (via syslogging on a management server, for example) and back them up periodically. Security alerts should be sent to IT staff via group notifications rather than to individual recipients, and all alerts should be acted upon and documented immediately.
There should also be concise guidelines on protecting computer hardware and software from misuse, theft, unauthorized access, or environmental hazards. Therefore, all devices should be kept in physically secure areas whenever possible: servers, backup devices, switches and routers located in a closed data center and wireless access points in locked cabinets, etc. Only authorized persons are permitted to enter these secure areas. and all access must be logged as necessary. Where possible, biometric controls, such as fingerprint or retina scanners, should be used.
Finally, the policy should cover compliance with periodic review of the environment to decommission all devices that are no longer in use. Ensure backups are performed consistently and reliably so that data can be restored if it is altered, lost, stolen, or maliciously breached.
