Has anyone noticed that IT is no longer the same as it was a few years ago? Apart from the IT team, we are now concentrating on network infrastructure and security. The expectation of today’s work-from-anywhere workforce is for IT to enable seamless and secure connectivity to all devices and for our business tools to be highly personalized and instantly available. They require frequent maintenance and vulnerability patches to ensure that vulnerabilities do not exist. Misconfiguration, incorrect configuration processing, and weak encryption keys can expose the entire network to risk.
In today’s world, generally ensuring network security and safeguarding network equipment is the best option for any company. To protect the company from cyber dangers, it is essential to start implementing security solutions.
Network security with cyber security–
The Zero Trust Paradigm is defined as a security model, a set of systems design principles, a coordinated cybersecurity, and a systems management strategy. The security guidelines presented here will introduce new network designs aimed at more mature zero-trust principles to mitigate common vulnerabilities and deficiencies in existing networks.
In simple terms, Network security is a set of settings and regulations that use software and hardware technologies to protect the integrity, confidentiality, and accessibility of computer networks.
Given the current circumstances and the increasing magnitude of cyberattacks due to the pandemic, everyone working to strengthen network security needs to be aware of network-related cyberattacks. Let’s review the core network infrastructure and security design in more detail.
The six guidelines of network architecture and its design –
We’ll look at the six main elements of network security now that we’ve covered the basics, architecture, and design.
one. Perimeter and Internal Defense Devices to be installed–
Multiple layers of defense against external threats must be created as the strategy is defensive to protect individual components:
• Incoming and outgoing traffic must be logged to a network monitoring service.
• To control traffic, firewalls must be implemented throughout the network.
• An ISP (Internet Service Provider) will be installed to help with external network connection.
• Multiple dedicated remote log servers are deployed.
two. Similar network systems to be grouped – To prevent adversary lateral movement, similar systems within network devices must be grouped together. It is recommended that similar systems be separated into separate subnets, VPNs, or routers. Workstations, servers, and printers, for example, must be kept separate.
3. Tailgate connections to be removed- Backdoor connections are defined as connections between two or more devices in different network zones. It is strongly recommended that all backdoor connections be removed and that care be taken when connecting devices to multiple networks.
Four. Access control perimeter to use – Apply a perimeter rule that specifies which connections to allow, and create rule sets that focus on allowing only those connections and denying any others. The main purpose of this rule is to allow a single rule to deny multiple types of connections. To prevent unnecessary access to the internal network, these access control parameters must be configured with the appropriate laws.
5. NAC (Network Access Control) is a solution – Consider a solution that discovers and authenticates every single device connected to the network. Unauthorized physical connections are prevented and approved physical connections are monitored by a NAC system. An example of this is port security, which seems to be difficult to control.
6. VPN gateways will be limited – The most crucial gateway is a VPN, which can be accessed over the Internet and is vulnerable to brute force attacks, network scanning, and zero-day vulnerabilities. These flaws must be mitigated by removing all unnecessary functionality and implementing strict traffic filtering rules.
Perform regular network tests –
A lots of vulnerabilities and security pitfalls can be avoided by following the aforementioned network security and infrastructure principles. In light of this delicate scenario, it is imperative that we all remain cyber-aware and safe while working. Organizations are expected to take the initiative to provide proper cyber awareness training to employees and help them combat today’s cyber attacks.
With so many security issues and network vulnerabilities attacking the network these days, being proactive and addressing these flaws as soon as possible is the only prudent course of action.
Network assessment and penetration tests can help you find vulnerabilities in your network architecture that could be exploited. As a result, get in the habit of performing network penetration tests on a regular basis to keep your business safe from internal and external threats.
