Network Security Requirements – Network security is the activity of preventing and protecting data and information in a network system. which usually exists within a corporation, from unauthorized interference or not part of the access to legitimate info or data. Includes technology, tools and processes to secure everything on the network system.
In the use of internet and cloud-based networks, secure data and information are of prime importance. Cloud or network that is used fast and easily accessible will remain in vain if it is not safe in it.
Reasons for the Importance of Network Security
Creating this involves five reasons, namely confidentiality, integrity, availability, authentication (data authentication), nonrepudiation (minimal denial), and access control (access control). Confidentiality requires that information or data in the system can only be accessed by a number of authorized parties. Integrity requires that information can only be changed by authorized parties.
In addition, availability requires that information is only available to the authorities when needed. Authentication requires that the sender of the information can be properly identified and not a fake user. Nonrepudiation requires that the sender and recipient of the information cannot deny or reject the sending or receiving of information. Access control is an attempt to manage access by using a combination of user ID and password or other complicated mechanisms so that they are not easily hacked.
Types of Attacks on Network Security
As something related to security, there are several types of attacks or disturbances that are capable of attacking, namely interruption, interception, modification, and fabrication. This attack or interference can endanger data or information in the system.
In detail, interruption is an attack so that a secure system is no longer available or used by genuine or authorized users. Interception is tapping data in a network hacked by parties in the form of programs, systems, to individuals. Modification is a change in the value of data or information so that it does not contain things that should be. While fabrication is sending fake messages or data to others for fraudulent purposes.
Important Elements of Network Security
In practice, the elements of the formation of network security are contained in two main elements. A safety wall in physical or virtual form functions as a protector. While the security plan is an implementation to protect against various risks of hacking.
Network Security Requirements
For good network security, there are three conditions that can be declared safe protected. There are prevention, observation, and response. These three conditions are very necessary in order for a network system to remain safe from interference.
Prevention is an attempt to stop unwanted access in a network system. This can be done by choosing the configuration service carefully. Observation is a maintenance process in the form of seeing the contents of the log whether there is abnormal activity or not. This can be done via the IDS system as part of the observation process. While the response is the action taken when there is hacking or infiltration in the network system.
Basic Things You Must Have in Network Security
Network security must consist of the fundamentals for safe and good. Network security must have protection (detection), detection (detection), and reaction (reaction). Protection is a network system configuration that must be accurate. Detection is an identification of when configuration changes must be made and monitoring of network traffic that shows or is not a problem. While the reaction is to identify the problem quickly respond and return it to the safe condition as before.
In strengthening network security, there are several types of techniques and types that you should recognize and know. By knowing these types and types, you can choose and master the most appropriate and safe for the network system that you protect.
There are access controls, anti-malware, application security, behavioral analytics, data loss prevention, email security, Firewalls, intrusion detection and prevention and intrusion prevention), mobile devices and wireless security (network devices and wireless security), network segmentation, information security and event management (information security and event management – SIEM), VPNs, and web security (web security).
Everything and details about network security methods must be well studied because this method has an important role. One of the professions required to learn this method is the administrator. The tasks and roles of the network security administrator can be seen in the following details.
Important Tasks of Network Security Administrators in Network Security
In maintaining network security, there is an important role that must be present in securing this network system, namely network security administrators. Network administrators are individuals or groups who manage and maintain all the elements that exist on and within the network system to make it more effective and efficient work. Certainly, the task of the network administrator also plays an important role in the strength of network security.
Network Security administrator or network security administrator must have general skills and abilities, namely basic and technical knowledge about computer theory and practice, knowledge of various computer network hardware including how to work, install, and configure devices, and have an understanding of routing or system configuration. including about computer security systems and their networks. All of these skills must also be packaged with good professional ethics.
An important task of network security administrators is to deal with networks, hardware, and applications. Specifically, the task of network security administrators is dealing with security management that deals with network security. To be able to achieve good security management, a network security administrator must master the firewall (the permissions system and network traffic), user access (log in information with password control), and resource access (limiting the use of network systems by giving access rights to several people only ).
The use of network security requires regulation at the physical and non-physical levels. This arrangement involves the control process. The process of controlling network security that must be understood by network administrators involves controlling corporate strategic (controlling strategic companies in the form of assets), controlling complexity (controlling plurality of systems), improving service (increasing service usage), balancing various needs (balancing various needs), reducing downtime (reducing termination), and controlling costs (controlling costs incurred).
