Network Infrastructure Security This is typically used in enterprise IT environments and involves the installation of preventative measures to block unauthorized access to, modify, delete, or steal data and resources. Access control is one example of security measures. Application security Firewalls, virtual private network (VPN), behavioral analysis Intrusion prevention systems Wireless security.
What is the security of Network Infrastructure Security?
Network Infrastructure Security is a comprehensive approach that includes ongoing processes and practices. This will ensure that the infrastructure remains secure. When deciding which methods to use, the Cybersecurity and Infrastructure Security Agency recommends that you consider multiple approaches.
- Segment and segregate networks, functions The overall infrastructure layout should be given special attention. Segmentation and segregation are a good security measure to prevent potential intruder exploits spreading into other parts. Hardware such as routers can be used to separate networks and create boundaries that filter out broadcast traffic. These are micro-segments The network can be further restricted or shut down if attacks are detected. Virtual separation works in the same way as physical separation, but without the hardware.
- Avoid unnecessary lateral communication Peer-to-peer communication within a network is important. Intruders could be able to freely move from one computer to the next if there is unfiltered communication between peers. By installing backdoors and applications, attackers can establish persistence in the target network.
- Harden network devices -Network security can be improved by hardening devices. It is recommended to follow industry standards and best practices in network encryption, available service, securing access, strong usernames, protecting routers and restricting physical access. Backup configurations are also important and to test security settings periodically.
- Secure access to infrastructure devices –Administrator privileges are granted to trusted users to gain access to resources. Multi-factor authentication (MFA) is used to verify the authenticity of users. It also allows for management of privileged access and administrative credentials.
- Manage out-of-band networks (OoB). OoB management uses dedicated communication paths to remotely manage network devices. This increases the effectiveness of OoB management. Network security Separate user traffic and management traffic
- Verify the integrity of software and hardware Gray market products can be a threat to IT infrastructure, as they provide a way for hackers to attack a network. Illegitimate products may be preloaded with malicious software that can be used to infiltrate networks. It is important that organizations regularly conduct integrity checks of their software and devices.
What is Network Infrastructure Security?
Hackers and malicious programs that attempt to take control of the routing infrastructure are the greatest threats to network infrastructure security. All components of network infrastructure include routers, firewalls and switches as well as load-balancers, intrusion detection system (IDS), domain names system (DNS) and storage systems. Hackers can gain access to these systems to install malicious software on target networks.
- Gateway Risk Hackers can gain access to gateway routers and monitor, modify and deny traffic within and outside the network.
- Infiltration Risk Hackers can gain more control over the internal routing devices and switching devices and monitor, modify and deny traffic among key hosts within the network. They also have the ability to exploit the trusted relationships between internal hosts in order to move laterally to others.
While hackers can do a lot of damage to a network, it is important that you secure and defend the routing infrastructure in order to prevent system infiltration.
What are the benefits to Network Infrastructure Security?
When implemented correctly, network infrastructure security can provide several key benefits for a business’s networks.
- Cost savings can be achieved through improved resource sharing Multiple users can use the network’s resources without being threatened, which ultimately reduces the overall cost of operation.
- Licenses for shared sites: Site licenses are cheaper than each machine licensing because of security.
- File sharing improves productivity: Files can be securely shared across the network by users.
- Secure internal communications Internal email and chat systems will not be accessed by prying eyes.
- Secure files and compartmentalization Users files and data are now more secure than machines shared by multiple users.
- Data protection Backup of data to local servers can be simple and secure. This protects vital intellectual property.
What are the various types of Network Infrastructure Security?
There are many ways to secure your network infrastructure. It is important to use multiple methods to strengthen your network defense.
- Access Control It prevents unauthorized users from accessing the network.
- Application Security Hardware and software security measures are implemented to protect against potential vulnerabilities.
- Firewalls Gatekeeping devices are used to control traffic and allow it to enter or leave the network.
- Virtual Private Networks (VPNs): VPNs secure connections between endpoints, creating a “tunnel” of encrypted communications over the internet.
- Behavioral Analytics These tools detect network activity that is different from normal activities automatically.
- Wireless Security Wireless networks are less secure that hardwired networks. With the proliferation of mobile apps and new devices, there are more ways to infiltrate networks.
