Network security is crucial for businesses to protect their computer systems from hackers and data loss. A multi-layered security system, managed by the system administrator, including firewalls and anti-malware programs, is essential. Communication between management, administrators, and employees is critical for balancing security concerns with job requirements. Breaches are costly, so a multi-pronged approach is necessary for effective protection.
Network security encompasses the measures a business takes to protect its computer system and is a primary concern for any business that uses computers. Compromised network security means that a hacker or competitor can gain access to critical or sensitive data, possibly resulting in data loss or even complete system destruction.
Appropriate security for a network is achieved when a user has to go through several layers of security before being able to access the desired network. The more layers the system has, the more secure it is.
The system administrator is often responsible for network security as they have administrator privileges on the system. In fact, only the system administrator and his assistants should have administrative access to the mainframe server and related computer terminals. This will help prevent unauthorized people from the company from changing the data on the servers.
A system administrator will also create a secure firewall for the network, which may include a layer of encryption and sentinel software that automatically prevents an unauthorized program from gaining access. The administrator can also place restrictions on employee computers to prevent them from accessing websites that may contain malicious code or malware that will install itself on a user’s computer. Anti-adware and malware programs are available for both individual computers and networks.
One problem that generally arises with this type of security is flexibility. Management needs to balance security concerns with employees’ ability to access websites for their jobs. Communication between management, the system administrator, and employees is critical to the operation of network security and for employees to work with it.
As demonstrated in dealing with past email and network viruses, security breaches are costly and detrimental to production and efficiency. US companies spend millions of dollars each year on network security measures. A company’s best defense against breaches is a multi-pronged attack. Firewalls without a single entry point, smart system administrators, frequent security updates, and early installation of anti-adware will help keep your network safe.
