Vulnerable points in networking
Netorks are being vulnerable to attck by outsiders but there are some internal factors on which network is based and should give due considertaion to avoid intrusion. The most points to enter your system can bs as follow
1. Modems. The lack of password management can easily allow outsiders to intrude to your system. There must be check on this pont. One can notice many enterprise wifi passwords are not strong enough.
2. Open file transfer. Most organizations use open file transfer to patch network infrastructure. Internal technicians and vendors use this poorly secured, unrestricted access to troubleshoot, apply appropriate fixes and correct problems.
3. Open telnet and SSH ports.Companies that use third parties to remotely access and troubleshoot systems should properly secure or close telnet and SSH ports. Without these protections in place, all a remote technician needs is a single internal IP address to get anywhere on your network without your knowledge.
4. Server console ports. Technicians frequently connect to serial console ports, very often on routers and Linux/Unix servers. To provide scalable access, companies will typically connect to serial console ports using terminal servers. However, terminal servers, by default, offer minimal security.
5. Unmonitored extranet traffic. Extranets provide a convenience for companies, allowing them to open their networks to vendors, customers and partners to support real-time collaboration.
