There are several steps that can be taken to improve network security management. These include limiting physical access, filtering network traffic, and educating staff on the importance of security. Ideally, your network security management strategy will combine these steps.
Network access control limits the scope of malware and cyber threats by assigning the right roles to users and devices. It can also restrict lateral movement within the network. It can help limit the damage of a cyber attack by requiring devices to re-authenticate themselves to the network. In addition to security, access control enhances performance. For example, it can be used to ensure that employees can access the Internet but that guests are not allowed to use the entire network. By segmenting employees and guests, you can limit the scope of risk and improve performance.
The security administrator can reduce risks by implementing network security management topped with additional measures, including biometric and multi-factor authentication. These additional measures can significantly reduce the risk posed by unauthorized users.
Filtering Network Traffic
Filtering network traffic is an effective way to manage network security. It can be broad or granular, depending on your network’s security requirements. Broadcast packets, for example, may only be allowed to reach a single IP address, while unicast packets may be directed toward various machines. You can also devise rulesets to restrict network traffic to specific IP addresses or prevent access to certain machines.
You will ensure that only necessary data is sent to network tools by filtering network traffic. This way, network security tools won’t waste time analyzing irrelevant network traffic.
Restricting Physical Access
Restricting physical access to networks and information systems can be critical to effective network security management. Enterprises can minimize risks by limiting physical access to networks and information systems. These controls ensure that only authorized individuals can access systems, operating environments, and equipment. In the digital age, however, physical access to systems has changed. Now, more than ever, employees are working remotely and relying on digital technologies to accomplish more than ever. However, with this increased efficiency comes the increased risk of cybercrime and hacking. As a result, networks and information systems must be secured from cyber-attacks.
Physical access can come in several forms, from physical barriers to security guards to video cameras. These controls can help prevent unauthorized access and create a forensic-friendly data environment. Ultimately, the goal is to secure sensitive information from unauthorized users.
Educating Staff On The Importance Of Network Security
One of the best ways to increase cybersecurity awareness among your staff is to offer regular training and refresher courses. The right training should cover various topics, from different hacking methods to cybercrime, from malware to passwords and desktop security. It should also include a simple assessment process, showing where your staff stands regarding cybersecurity awareness. If they feel they are unaware of security issues, you can tailor a program to their level of knowledge and abilities. Educating staff on cybersecurity is vital because it is your company’s first defense against cyber threats. They need to know how their actions affect the company, and they need to work together to secure company data.
Implementing A Company-Wide Security Policy
Implementing a company-wide security policy is one of the best ways to ensure that your organization is protected from security threats. A policy covers various topics and should be easy to read and understand. It can also help create an atmosphere of accountability and a “security first” culture. Once the policy is in place, it should be reviewed and approved by the executive leadership. A good policy should also include incident response.
When implementing a security policy, you should ensure that everyone knows about it and understands the importance of security.
