Was tun Sie, wenn Ihre Netzwerksicherheit optimiert werden muss?

The following steps are taken: 1. Identify the areas that need improvement: This can be done by conducting a security audit or by reviewing your current security policies and procedures. 2. Prioritize the areas that need improvement: Once you have identified the areas that need improvement, you need to prioritize them based on the risk they pose to your organization. 3. Develop a plan to address the areas that need improvement: This plan should include specific steps that you will take to improve your security, as well as a timeline for completing the steps.

Network optimization is an ongoing process. Continuously monitor performance, adapt to evolving threats, and maintain a secure network environment is essential.

1. Assess current security. 2. Set clear security goals. 3. Update all software. 4. Use strong authentication. 5. Encrypt data in transit and at rest. 6. Segment the network. 7. Monitor network traffic. 8. Educate users. 9. Conduct regular audits. 10. Have an incident response plan. 11. Consider expert assistance when needed.

Conduct a Security Assessment: Start by conducting a comprehensive security assessment of your network infrastructure to identify existing vulnerabilities, weaknesses, and potential risks. This assessment should cover all aspects of network security, including hardware, software, configurations, policies, and procedures.

Several years ago in one of my roles as a Network Infrastructure Engineer, we had an open source software firewall which was installed on a server hardware. This provided us with excellent firewall capabilities, including web content filtering/logging. Hoever, as websites migrated to HTTPS, we realised that blocked websites/content are now getting pass the firewall. In the course of my investigation, I realised the software lacked the ability to perform deep packet inpection, hence was not able to handle https traffic. Updating and upgrading the solution solved the problem.

Updates often include patches for known security vulnerabilities, which attackers can exploit to gain unauthorized access to your system. Unless it’s a zero day attack, up to date OSs and AV Softwares usually set up a good defense system.

Benefits of Secure Access: Protects sensitive information from unauthorized access and data breaches. Ensures compliance with regulatory requirements and industry standards. Improves overall security posture and reduces the risk of cyberattacks. Enhances user confidence and trust in the security of systems and data. Implementation Considerations: Risk Assessment: Identifying potential threats and vulnerabilities to determine appropriate security measures.

Secure network access is an important concept, wether as a user accessing network resources or as an administrator configuring and managing devices. MFA is important for the former, as for the later, you can employ access control lists (ACLs) to restrict network access based on user roles, privileges, and other criteria. Only authorized users should have access to specific resources. SSH over Telnet is also a handy point to note.

Mobile VPN could be the solution for most of the problems of this kind. Not just for the efficiency that it provides to the company/campus users but the zero risk. When user is out of the campus, mVPN can ensure a secure connection thanks to the ULCL and in that way avoiding public network hazards.

Several years ago, I once deployed an Intrusion Detection System (IDS) in the organizational netork infrastructure, which helped me to keep an eye on some suspicious inbound traffic. This revealed an open remote desktop port to an internal host - and the port was opened using the standard RDP port 3389, which is not an optimal network security configuration. Monitoring traffic is quite important to ensuring network secutity optimization.

We shouldn´t forget that not only threats are coming from packet core network. Carriers/operators should ensure security in the same way in IMS network by deploying mechanisms to avoid scams in voice calls, a way to enable this "scam detection" is to analyze by some "Call inspector" or TAS the duration, OT&DT, or even the location from them. Only in USA, they receive more than 30 million Scam calls per day...

The cost of a secure network is the constant monitoring, I always use tools like Wireshark to monitor what type of traffic is traveling among the routers and switches, looking for unknown or unauthorized connections, for example, telnet in administrative VLANs, unsuccessfully HTTPS response, and so on, delta time between packets. every behavior that can be suspicious.

Training users on network security is crucial for maintaining a secure digital environment. Basic aspects that you might need to include in the training involve, Phishing awareness, Incident reporting as well as password management.

It is proven that users are the weak link in the security chain, therefore training users to report any thing they find suspicious remains an important factor to consider in optimizing network security.

Incident Response could be help but attention to all CR procedure for Optimization due to solve their exact problem at first and kept Risk to reward ratio in optimum value .

Incident Response is a critical part of any organization's security program. By following a standardized process, organizations can improve their ability to respond to and recover from security incidents, and minimize the impact of these incidents on their operations.
