In this era of Internet of Things, ensuring that the organizations network traffic is always secure, whether on premises or cloud based has become a critical part of data protection strategies. This ensures that an organization data is safe from landing into unauthorized hands where it can be used to deter the organization. Implementing both secure wired and wireless environment within an organization set up, there are some steps necessary
Microsoft has come up with a number of security technologies to make it easy when it comes to protecting an institutions network. These technologies include, firewall, intrusion detection systems, partitioned LANs, traffic isolation, access control, Azure security center and Multi-tier topology (Karygiannis & Owens, 2012).
The current networked world has been shifting constantly and the devices it connects also change from time to time. The combination of cloud based services, on-premises computation and the mobile workforce armed with the expanding diversity of connectivity devices calls for advanced security systems in network and which are flexible as well as agile to be in a position to detect malware activities and intrusions (Karygiannis & Owens, 2012).
Steps to Implementing Network Security
Organizations must deploy rigid cyber defense systems, systems which must be able to focus on the Meta environment surrounding the organization technology as well as the specific vulnerabilities. The following areas must be considered before implementing windows network security (Karygiannis & Owens, 2012).
Visibility of Traffic
With the virtualization of destinations and origins, the network traffic has grown complicated. The gap between virtual and physical environments implies that it is no more viable to say certain physical systems are secure, simply because both the application and the data served by virtual devices can exist over various physical systems. Security systems therefore are supposed to be in a position to identify, monitor and evaluate traffic, not considering source and destinations (Zhang & Lee, 2015).
Encryption and decryption
The interception techniques available today have made it trivial for intruders to listen to network traffic and therefore making encryption very important than ever before. However, the same encryption protecting data in transit has made it hard to detect malwares hidden in encrypted data. Cybersecurity systems to be implemented should therefore be in a position to decrypt traffic in order to evaluate it while up keeping data confidentiality and security (Zhang & Lee, 2015).
Segment Content Delivery
All content in an organization does not require same threat analysis. The security professionals are therefore supposed to direct different security issues to the systems which are designed to handle such the best. For instance, YouTube videos are evaluated differently from mail chats. Network traffic has to be segmented to allow best utilization of security analysis and bandwidth (Zhang & Lee, 2015).
Inline and Out of Band Security
Inline network is a real time security monitoring standards, but the advanced persistent threats (APTs) have the ability of infiltrating the computing resources and become active after certain period of time. Out of Band Security need to be implemented to allow the analysis of threats that already penetrated the network and probing vulnerabilities with a potential of launching attacks (Zhang & Lee, 2015).
