The development of office automation has gone through four stages: the word processing realized from the PC and personal office software is the first stage, this stage is about the 80s to the early 90s, we mainly realize word processing, that is, the office automation of a single machine; The second stage is the emergence of local area networks, which and relational databases have realized file sharing and information sharing, which should be in the early 90s; The third stage, which is characterized by office automation based on groupware technology and aimed at collaborative work and knowledge management. The fourth stage, the collaborative office portal, is characterized by the OA system as the entrance to the internal informatization of the entire organization, as opposed to the external portal (Internet**).

The development of the office system has gone through five stages: the word processing realized from the PC plus personal office software is the first stage, which is probably in the 80s to early 90s of the 20th century, and the role of OA is to realize word processing, that is, the office automation of a single machine; The second stage is the emergence of local area networks, which and relational databases have realized file sharing and information sharing, which should be in the 90s; The third stage, at the beginning of the 21st century, is characterized by office automation based on the noisy technology of groupware, with collaborative work and knowledge management as the goal.

The OA system is an application system invented to meet the needs of more efficient achievement of an organizational goal. Since the beginning of modern civilization, with the development of computer technology and the development of enterprise organizations, the current OA system software has been produced!
The organization is based on the realization of the goal and is structured with a certain relationship, and any instruction information of an organization must be issued by people - just like the human heart directs the flow of blood; The instructions issued must be carried out through the path (meridians); The execution process is the exchange or update of information - blood spine feeding tissue unit, and the tissue unit is a hematopoietic unit. That's how any organization works, and the OA system is designed to help keep the organism in optimal health at all times!
Therefore, we can understand the OA system as: take the goal as the program, the organizational structure as the skeleton, the human heart, the workflow as the meridian, and the knowledge and information as the blood, so that all departments and personnel inside and outside the organization can work together to achieve the organizational goals.
At present, the OA system is a key branch of the management software category, and in addition to the collaboration system (organization management system) software, there is another core branch: ERP system (business management department) software.
In an organization, business software such as ERP is like an organization's military attaché to open up the country for the organization - with business data management as the core; Organizational management software such as OA system is more like an organization's civil officials to do a good job of governance for the organization - with the behavior management of organizational personnel as the core; A good civil official must understand some business, and a good military attache must also understand some civil governance, so there is also an integration requirement between the OA system and ERP business, and both civil and military personnel make organizational collaboration more efficient.

Your network architecture is a medium-sized network, don't use class C IP, change to class B, divide several VLANs, divide the office building into a VLAN, each office is divided into VLAN, and then put the OA and business system server separately into a VLAN, the default VLAN can be, easy to manage, but also can prevent ARP attacks, and then there are ARP attacks can only attack in this VLAN, will not affect the server, you can enable the routing function on the main switch, Support cross-VLAN data exchange, control the direction of data exchange through ACL, how do you usually manage the external network, you can see if you need to change it again, as for ARP detection, your VLAN should be attacked in a certain VLAN after it is divided, you can know which switch under the computer issued the ARP attack, you can then go to the corresponding switch web page through the MAC detection function to detect the attacker's MAC and IP, Even if someone manually changes the MAC and IP, the above will also be recorded, as for what you said can not find the attacker's MAC, it may be manually modified, you can find the attacker's real MAC address and IP through the MAC detection function on the web page, you can easily find out which computer is attacking, in this way, the network is safe, viruses, and human aspects are all eliminated After reading your information above, I feel that your network is a little messy, and you can apply to move the network once, Let's make a rectification and re-plan.
